    The present invention relates to a method of firing an electronic detonator, and an electronic detonator implementing the firing method.
    In general, a set of electronic detonators is connected to the same control system, the control system being configured to manage the operation of the electronic detonators, as well as to power them.
    Each electronic detonator is connected to the control system by means of electrical conductors (corresponding to the son of the detonator, the bus line and the firing line), and includes in particular an explosive or detonator charge, a primer or ignition module to electronic control, and means for memorizing a firing delay time, this delay time corresponding to the time to be counted between the reception by the electronic detonator of a command or firing order and the firing well said.
    Thus, an electronic detonator further comprises electronic circuits configured to reproduce the firing delay time, for example by performing a count corresponding to the delay time from the receipt of the command or the order of setting. traffic light.
    In some cases (for example, when the electrical conductor wires have been cut by one of the previous detonations), once the control system issues a firing command, the electronic detonators are no longer powered by the control system. supply of each electronic detonator being ensured by onboard energy storage means in each detonator.
    The energy storage means on board an electronic detonator make it possible, in addition to feeding the various electronic circuits in the detonator such as the circuits reproducing the delay time, the storage of the energy necessary for firing the electronic detonator. .
    If the energy stored in the energy storage means decreases so that the means of the electronic circuits are not powered, the ignition delay time is not reproduced, the firing of the electronic detonator does not occur. not being implemented.
    Similarly, the electronic detonator is not fired if the energy stored in the energy storage means decreases so that the energy required for firing is not sufficient in the storage means of energy, especially once the delay time has elapsed.
    Failure in firing an electronic detonator presents a significant safety risk.
    The present invention aims to provide a method of firing an electronic detonator, and an electronic detonator in which the security is improved. In this regard, the present invention aims in a first aspect a method of firing an electronic detonator comprising energy storage means, the method comprising receiving by the electronic detonator a firing order.
    According to the invention, the method comprises the following steps implemented as long as a delay time associated with the electronic detonator has not elapsed from said reception of the firing order: - measurement of a energy stored in the energy storage means, and - firing the electronic detonator when the measured stored energy is less than or equal to a predetermined energy.
    Thus, as soon as the electronic detonator receives a firing command and as long as the delay time associated with the electronic detonator has not elapsed, the energy stored in the energy storage means is monitored so as to firing the electronic detonator if the measured stored energy is less than or equal to a predetermined energy.
    Therefore, the method allows an electronic detonator to be fired although the delay time associated with it has not elapsed since the receipt of the firing command.
    This represents a means of controlling the firing of the electronic detonator other than by the countdown of the delay time and thus to improve the security relative to the electronic detonator.
    For example, the predetermined energy corresponds to a minimum energy required to power and to ignite the electronic detonator.
    Therefore, when the energy stored in the energy storage means reaches a minimum value that no longer allows the supply and / or firing of the electronic detonator, the firing of the electronic detonator is implemented without waiting the lapse of the delay time.
    Indeed, when the stored energy is greater than the predetermined energy, the energy storage means contain the energy necessary to power the electronic detonator and for the actual firing.
    On the contrary, when the stored energy reaches the predetermined energy or is lower than the predetermined energy, there is a risk of not firing the electronic detonator.
    Thus, the electronic detonator is fired as soon as the energy stored in the energy storage means reaches the predetermined energy in order to prevent the electronic detonator from ever being fired.
    Note that if the stored energy is lower than the predetermined energy, the delay time count can not be implemented and therefore the electronic detonator will never be fired although there is still energy necessary for the firing, the countdown of the delay time can be implemented but the energy remaining in the storage means is not sufficient for the firing, or there is no energy left for the firing. neither for the firing of the electronic detonator.
    According to one characteristic, the firing process further comprises a step of comparing the measured stored energy with the predetermined energy.
    According to one characteristic, the step of measuring the stored energy comprises a step of measuring a voltage across the energy storage means, and the comparing step comprises a step of comparing the measured voltage with a predetermined voltage representative of the predetermined energy.
    Thus, when the voltage measured at the terminals of the energy storage means is less than or equal to the predetermined voltage, the firing step of the electronic detonator is implemented before the delay time has elapsed.
    Indeed, if the voltage measured at the terminals of the energy storage means is less than or equal to the predetermined voltage, the electronic detonator is fired before the energy stored by the energy storage means is no longer sufficient. for the electronic detonator to be fired.
    Thus, the electronic detonator is fired while there is enough energy to power it and to initiate the detonator charge of the electronic detonator.
    It follows that as long as the voltage measured at the terminals of the energy storage means is not lower than the predetermined voltage, the countdown of the delay time continues and the firing step of the electronic detonator is set implemented once the delay time associated with the electronic detonator has elapsed.
    According to one embodiment, when the measured stored energy is less than or equal to said predetermined energy, the method further comprises a step of determining the time difference existing between a period of time elapsed from the reception of the firing order and the delay time associated with the electronic detonator, said firing step being implemented when said time difference is less than a predetermined time value.
    Thus, according to this embodiment, although it has been found that the measured stored energy is less than or equal to the predetermined energy, it is checked whether the time difference between the associated delay time and the elapsed time since the reception of the firing order is less than a predetermined time value, the firing step being implemented only, if the time difference is less than or equal to the difference value of predetermined time.
    On the contrary, if the time difference is greater than the predetermined time value, the countdown of the delay time associated with the electronic detonator continues.
    In one embodiment, the step of measuring the stored energy comprises a first step of measuring the energy stored in first energy storage means and a second step of measuring the energy stored in seconds. energy storage means, the firing of the electronic detonator being implemented if the stored energy measured at the first measurement step is less than or equal to a first predetermined energy or if the stored energy measured at the second step of measurement is less than or equal to a second predetermined energy.
    In this embodiment, the first predetermined energy corresponds to a minimum energy required to power the electronic detonator and the second predetermined energy corresponds to a minimum energy required to ignite the electronic detonator.
    In addition, the comparison step comprises a first step of comparing the stored energy measured at the first measurement step with the first predetermined energy and a second step of comparing the stored energy measured at the second measurement step with the second predetermined energy.
    In this embodiment, the energy storage means of the electronic detonator thus comprise two different energy storage means, the firing of the electronic detonator being implemented when the stored energy measured in the first measurement step is less than or equal to the first predetermined energy and / or the stored energy measured at the second measurement step is less than or equal to the second predetermined energy.
    It is thus possible to separately monitor the minimum energy required to ignite the electronic detonator and the minimum energy required to power the electronic detonator.
    When one of the energies reaches a minimum value, the electronic detonator is fired by anticipation.
    The present invention aims according to a second aspect an electronic detonator comprising energy storage means and means for receiving a firing order.
    According to the invention, the electronic detonator further comprises: - means for measuring an energy stored in the energy storage means, and - firing means configured to implement the firing of the detonator electronics before a delay time associated with the electronic detonator does not flow, when the stored energy measured by the measuring means is less than or equal to a predetermined energy.
    According to one characteristic, the electronic detonator comprises means for comparing the stored energy measured by the measuring means with said predetermined energy.
    According to one characteristic, the means for measuring the energy stored in the energy storage means comprise means for measuring the voltage at the terminals of said energy storage means, and the comparison means comprise means for comparing the energy a voltage measured by the measuring means at a predetermined voltage representative of the predetermined energy.
    In one embodiment, the energy storage means comprise first energy storage means configured to store the energy required for the supply of the electronic detonator and second energy storage means configured to store the energy. energy required for firing the electronic detonator.
    Thanks to the different energy storage means for storing the energy necessary for supplying the electronic detonator and for storing the energy necessary for firing the electronic detonator, it is possible to measure the voltage at the same time. terminals of each of said energy storage means and firing the detonator when one of the voltages is less than or equal to a predetermined voltage.
    According to one characteristic, the energy storage means comprise a capacitor.
    The present invention aims according to a third aspect, a detonation system comprising a set of electronic detonators according to the invention and implementing the firing method according to the invention.
    The electronic detonator and the detonation system have advantages similar to those described above with reference to the firing method according to the invention. Other features and advantages of the invention will become apparent in the description below.
    In the accompanying drawings, given as non-limiting examples: FIG. 1 schematically represents a detonation system according to an embodiment comprising several electronic detonators; FIG. 2 represents an electronic detonator according to one embodiment of the invention; FIG. 3 illustrates a flowchart representing the method of firing an electronic detonator according to one embodiment of the invention; and FIGS. 4a, 4b and 4c show examples of changes over time in the voltage at the terminals of the energy storage means.
    FIG. 1 represents a detonation system comprising several electronic detonators 1,2, ..., N.
    The electronic detonators 1, 2, ..., N are connected to a firing unit or control system 20 through electrical conductors son 30.
    The electrical conductors 30 comprise detonator wires, a bus line, and a firing line.
    The control system 20 is responsible in particular for supplying the electronic detonators 1, 2, N, to verify that they function properly and to manage their operation, for example to control their firing.
    To do this, the control system 20 comprises electronic circuits necessary to manage the operation of all the electronic detonators and to communicate with them.
    Thus, the firing unit or control system 20 generates supply signals as well as control signals, for example test signals or firing signals. These signals are sent via the electrical conductor wires 30 to the electronic detonators 1, 2,.
    Each electronic detonator 1,2, ..., N has a delay time associated with it, for example by receiving through the electrical conductors 30, the delay time from the firing unit 20, or by receiving by other wired or non-wired means from another unit, such as a console or programming unit (not shown in the figure).
    FIG. 2 represents an electronic detonator 1 according to one embodiment of the invention.
    The essential means for the implementation of the invention are shown in FIG. 2.
    The electronic detonator 1 comprises a heating resistor R intended to ignite a detonator charge (not shown in the figure) during the firing of the electronic detonator 1.
    The electronic detonator 1 further comprises energy storage means 100 necessary in particular for the supply of the electronic detonator 1 in the case where it is not powered by the firing unit 20, as well as for the firing proper of the electronic detonator 1.
    It should be noted that before a firing command is issued by the firing unit 20, the electronic detonator 1 is fed through the electrical conductor wires 30. In particular, a supply signal coming from the firing unit 20 is straightened by a rectifier bridge 300 connected to the input of the electronic detonator 1, the power supply signal charging the energy storage means 100.
    In the embodiment shown in FIG. 2, the energy storage means 100 comprise first energy storage means 101 configured to store the energy required to power the electronic detonator 1, and second energy storage means energy storage 102 configured to store the energy required for firing the electronic detonator 1.
    According to other embodiments, the first and second energy storage means 101, 102 may be replaced by single energy storage means storing the energy required for feeding the electronic detonator 1 and for its Firing.
    In the embodiment shown in FIG. 2, the first and second energy storage means 101, 102 respectively comprise a capacitor.
    The capacitor of the first storage means 101 is called the supply capacitor 101 and the capacitor of the second storage means 102 is called the firing capacitor 102.
    Thus, the supply capacitor 101 has the energy necessary to maintain the supply voltage of the electronic detonator 1 and, in particular, the electronic circuits necessary for the operation of the electronic detonator 1, for a period of time.
    The firing capacitor 102 stores the energy required to maintain a voltage necessary for firing the electronic detonator 1.
    The electronic detonator 1 further comprises a control module 200 comprising electronic circuits necessary for managing the operation of the electronic detonator 1.
    For example, the control module 200 controls the opening and closing of the switches T1, T2 respectively for charging the firing capacitor 102 and for connecting the firing capacitor 102 to the heating resistor R when the electronic fuse 1 is turned on. traffic light.
    For example, the control module 200 comprises a microcontroller 201 configured to manage the operation of the electronic detonator 1.
    In particular, the microcontroller 201 comprises means for receiving a firing order. This firing order is received from the firing unit 20. It further comprises means for counting the delay time associated with the electronic detonator 1, that is to say the time elapsed since the electronic detonator 1 receives the firing order of the firing unit or control system 20 and to initiate the firing once the time count reaches the delay time associated with the electronic detonator 1.
    The electronic detonator 1, and in particular the control module 200, furthermore comprises means for measuring the stored energy 202 in the energy storage means 100 and means for comparing the stored energy measured with an energy predetermined.
    In one embodiment, the means for measuring the energy stored in the energy storage means 100 include means for measuring the voltage at the terminals of the energy storage means 100 and the means for comparing the energy stored energy measured at a predetermined energy comprises means for comparing a voltage to a predetermined voltage.
    Thus, in the embodiment shown in FIG. 2, the measuring means comprise means for measuring the voltage at the terminals of the supply capacitor 101 and at the terminals of the firing capacitor 102.
    The measurement of the voltage at the terminals of the supply capacitor 101 makes it possible to know if it contains the energy necessary for the supply of the electronic detonator 1, in particular for the supply of the electronic circuits managing its operation 200.
    The measurement of the voltage at the terminals of the firing capacitor 102 makes it possible to know whether it contains sufficient energy for the firing itself of the electronic detonator 1.
    In one embodiment, the stored energy measurement means 202 comprise an analog digital converter 202 (CAN or ADC in English nomenclature for "Analog Digital Converter"). Thus, the voltage at the terminals of the supply capacitor 101 and the firing capacitor 102 is measured by means of the analog-digital converter 202.
    In this embodiment, the electronic detonator 1 comprises a single digital analog converter 202 for sampling the voltages at the terminals of the supply capacitor 101 and the firing capacitor 102. Thus, in this embodiment, the control module 200 comprises a multiplexer 203 having two inputs 203a, 203b and an output 203c.
    Of course, the electronic detonator could include two digital analog converters instead of a multiplexer.
    In other embodiments not shown, the energy measuring and comparison means may comprise other means, for example analog voltage measurement and comparison means.
    In the embodiment shown, the first input 203a of the multiplexer 203 is connected to the supply capacitor 101 and the second input 203b is connected to the firing capacitor 202. The output 203c of the multiplexer 203 is connected to the input 202a of the converter digital analog 202.
    The voltage across the supply capacitor 101 and the voltage across the firing capacitor 102 is sampled by the analog digital converter 202, each in turn.
    In particular, the microcontroller 201 provides for measuring the voltage across the supply capacitor 101 and the firing capacitor 102 periodically and of course only one at a time. Conventionally, the voltages at the inputs 203a, 203b are transmitted at its output 203c each in turn.
    Thus, when the microcontroller 201 controls the measurement of the voltage across the supply capacitor 101, the first input 203a of the multiplexer 203 is selected and the voltage at this first input 203a is transmitted to the output 203c of the multiplexer 203. that is, at the input 202a of the analog-to-digital converter 202.
    In the embodiment described, the voltage measured across the power supply 101 and firing capacitors 102 can be compared with a predetermined voltage representative of a predetermined energy, respectively.
    Of course, the predetermined voltages for the supply capacitor 101 and the firing capacitor 102 may have different values.
    The measurement and comparison of the voltages will be described later with reference to FIG.
    The output of the digital analog converter 202b is sent to the microcontroller 201 where the comparison means will compare the voltage received from the analog digital converter 202 to a predetermined voltage representative of a predetermined energy.
    In one embodiment, the predetermined energy corresponds to the minimum energy required to power the electronic detonator 1 and to ignite it.
    It will be noted that the predetermined energy takes into account a margin corresponding to the time elapsed between the moment when it is found that the electronic detonator 1 must be fired in advance and the moment of the actual firing.
    In another embodiment not shown in the figures, the energy storage means comprise a single capacitor in which the energy required makes it possible to maintain an adequate voltage for supplying the electronic detonator and for firing it.
    In this embodiment, the digital analog converter directly samples the voltage across said capacitor, without the need for a multiplexer.
    FIG. 3 represents a flowchart representing the method of firing an electronic detonator according to one embodiment of the invention. The electronic detonator is as shown in FIG.
    Of course, the firing method according to the invention can be implemented in electronic detonators according to other embodiments.
    In a detonation system as shown in FIG. 1, the electronic detonators 1,2,, N are powered or energized EO by the firing unit 20 by means of the electrical conductors 30.
    When the electronic detonators 1, 2, N are energized, they are listening to detect receipt of a firing order.
    The electronic detonators 1, 2, N are thus placed in this listening step E1 of a firing order.
    Of course, the electronic detonators 1, 2, ..., N can implement other tasks while listening to a firing order.
    The detection of the reception of a firing order is implemented during a verification step E2 of the reception of a firing order.
    When the reception of a firing order is detected during the verification step E2, the firing process includes a step of measuring an energy stored in the energy storage means 100.
    In the embodiment described, the step of measuring the stored energy comprises a step of measuring the voltage E3 across the energy storage means 100.
    This step of measuring the voltage E3 across the energy storage means 100 is implemented as long as a delay time associated with the electronic detonator 1 does not flow from the reception of the order of placing fire (or detection of receipt of the firing order at the verification step E2).
    In the embodiment described, corresponding to an electronic detonator such as that shown in FIG. 2, the measurement of the voltage E3 at the terminals of the energy storage means 100 comprises a first measurement across the terminals of the supply capacitor 101 and a second measurement across the firing capacitor 102.
    Of course, when only one energy storage means is present in the electronic detonator 1, 2, N, only one voltage measurement is implemented.
    In addition, the firing method according to the invention comprises a step of comparing the measured stored energy with the predetermined energy.
    In the embodiment described, the firing method comprises a comparison step E4 of the voltage measured at a predetermined voltage which is representative of a predetermined energy. The predetermined energy corresponds to a minimum energy necessary to power and to ignite the electronic detonator 1,2,, N.
    In an electronic detonator such as that shown in FIG. 2, the comparison step E4 comprises a first step of comparing the voltage measured across the supply capacitor 101 with a first predetermined voltage Va (FIGS. 4a, 4b and 4c). ) and a second step of comparing the voltage measured across the firing capacitor 102 to a second predetermined voltage VT (Figures 4a, 4b and 4c).
    Of course, the values of the first predetermined voltage Va and the second predetermined voltage Vj may be different or equal to each other.
    The first predetermined voltage Va corresponds to the minimum energy required for the supply of the electronic detonator. The second predetermined voltage Vj corresponds to a second minimum energy necessary for firing the electronic detonator.
    Of course, in the case of an electronic detonator comprising unique means of energy storage, a single voltage is measured at the terminals of the energy storage means, this voltage being compared to a single predetermined voltage corresponding to a minimum energy necessary to power and ignite the electronic detonator 1,2, ..., N.
    If at the comparison step E4 of the stored energy measured at the predetermined energy, the measured energy is less than or equal to the predetermined energy, a firing step E7 is implemented (early firing ).
    In an electronic detonator such as that shown in FIG. 2, if, at the comparison step E4 of the voltage, the voltage measured at the terminals of the supply capacitor 101 is lower than the first predetermined voltage Va, and / or the voltage measured at the terminals of the firing capacitor 102 is less than or equal to the second predetermined voltage Vj, the firing step E7 is implemented.
    Thus, when one of the voltages measured at the terminals of the supply capacitor 101 and the firing capacitor 102 is less than or equal to the corresponding predetermined voltage Va, Vj, the firing step E7 of the electronic detonator 1 is executed. without waiting for the delay time associated with the electronic detonator to have elapsed.
    In the embodiment shown in FIG. 3, when it is determined in comparison step E4 that at least one of the measured voltages is less than or equal to the corresponding predetermined voltage, the firing process comprises in addition a determination step E8 of the time difference existing between a period of time elapsed from the reception of the firing order, and the delay time associated with the electronic detonator 1,2, ... , NOT.
    When the determined time difference is less than a predetermined time value during this determination step E8, the firing E7 of the electronic detonator 1,2, .... N is implemented.
    On the contrary, when the deviation determined in the determination step E8 is greater than a predetermined time value, the firing process continues with the step of counting the delay time E5.
    Thus, in this embodiment, when a voltage across the energy storage means 100 is less than or equal to a predetermined voltage and the time gap exists between a period of time elapsed from receipt of the firing order and the delay time associated with the electronic detonator 1, 2, N is less than a predetermined time value, the firing step E7 is implemented although the delay time associated with the detonator electronic 1 has elapsed from the receipt of the order of the firing.
    If at comparison step E4, the voltages V-10-i, V102 (FIGS. 4a, 4b and 4c) measured at the terminals of the supply capacitor 101 and the firing capacitor 102 are respectively greater than the first predetermined voltage VA , and at the second predetermined voltage Vj, the countdown of the delay time E5 associated with the electronic detonator 1,2,, N continues.
    During a verification step E6, it is checked whether the delay time associated with the electronic detonator 1 2,... N has elapsed from the reception of the firing order. In the positive case, the electronic detonator 1,2, ..., N is fired during the firing step E7.
    Note that the firing of the electronic detonator 1, 2, ..., N once the delay time associated with it has elapsed, represents a case of firing implemented normally.
    As long as in the verification step E6 of the delay time associated with the electronic detonator 1,2,..., N, it is not observed that the delay time has elapsed, the measurement step E3 the voltage at the terminals of the energy storage means 100 (supply capacitor 101 and firing capacitor 102 in the embodiment described) as well as the comparison step E4 of the measured voltage with the predetermined voltage (first voltage predetermined VA, and second predetermined voltage VT) respectively is implemented.
    FIGS. 4a, 4b, 4c illustrate curves representative of the voltage values measured at the terminals of the supply capacitor 101 and at the terminals of the firing capacitor 102 as a function of time.
    FIGS. 4a, 4b and 4c represent a level of a first predetermined voltage VA representing the minimum energy required for the supply of the electronic detonator 1, 2,..., N, and a level of a second predetermined voltage Vj representing the minimum energy required for the actual ignition of the electronic detonator 1, 2, ..., N.
    The curve V101 represents the voltage at the terminals of the supply capacitor 101, and the curve referenced V102 represents the voltage at the terminals of the firing capacitor 102. The instant of time ti represents an instant at which a firing order is received by the electronic detonator 1,2, N (detection of the reception of a firing order during the verification step of the reception E2). Thus, at this instant of time t-ι, the countdown of the delay time associated with the electronic detonator 1,2, N begins.
    The second instant of time t2 shown in the figures represents the moment at which the electronic detonator 1, 2, ..., N is no longer powered or is partially powered by the firing unit 20.
    The third instant of time t3 represents the instant at which the countdown of the delay time associated with the electronic detonator 1, 2, ..., N has elapsed, at which moment the electronic detonator 1, 2,. to be fired.
    In FIG. 4a, the voltage at the terminals of the supply capacitor V101 and the voltage at the terminals of the firing capacitor V102 decrease from the second time instant t2 and remain always higher than the predetermined voltages VT, V0 for the supply capacitor 101. and for the firing capacitor 102 until the delay time has elapsed.
    Thus, in this case, the electronic detonator 1, 2, ..., N is fired at the firing step E7, once the delay time associated with it has elapsed .
    In the case represented in FIG. 4b, the voltage at the terminals of the firing capacitor 102 decreases very rapidly so that, at a time t3A, this voltage reaches the second predetermined voltage Vj corresponding to the firing capacitor 102. this instant t3A, the electronic detonator 1,2, ..., N is fired in advance, that is to say before the delay time elapses (time t3).
    In the case shown in FIG. 4c, the voltage at one terminal of the supply capacitor 101 decreases very rapidly so that it reaches the first predetermined voltage Va before the delay time associated with the electronic detonator has elapsed. (moment t3).
    The electronic detonator 1,2, N is thus fired at this time Î3a in advance, that is to say before the associated delay time has elapsed (time t3).
