    The invention generally relates to interlocking systems for a switch section of a railway track, in particular an interlocking system for a switch section of a railroad track. a railroad tramway.
    A known interlocking system is shown in FIG.
    System 1 equips a lane with a switch. This path comprises successively an upstream section 4, a switching section 10 and first and second downstream sections, 26 and 28.
    The switching section 10 has an input section 14, whose input corresponds to the output of the upstream section, the switch 15 itself, and an output section 17, whose output is common to the first and second downstream sections.
    The system 1 comprises an engagement device 30, which is a calculator disposed near the track portion incorporating the switch, and a plurality of equipment to the track, controlled by the interlocking device.
    The plurality of track equipment comprises: a communication equipment 40 of the short-range type, comprising an antenna disposed between the rail wires of the upstream section 4. The antenna is intended to pick up a control signal emitted by a tramway antenna when it passes over the ground antenna; - A first detection equipment 41 of the presence of a tramway on the input section 14. This equipment is constituted either by a track circuit, or by an axle counting device. It is capable of generating a detection signal of the presence of a tramway on the input section, which is a binary signal taking the value zero when no tramway is detected on the input section, or the value 1 when a tram is detected on the input section. - A signaling equipment 44, consisting of a light placed at the right of the switch and to indicate optically to the driver of the tramway the state of the switch section 10 and the current engagement position of the switch 15 ; - An actuating equipment 42 of the switch, for switching the switch in an interlocking position in the right lane, for the circulation of a tram from the upstream section 4 to the first downstream section 26, or in a switch-on position in deviated way, for the circulation of a tram from the upstream section 4 to the second downstream section 28. - A second detection equipment 46 of the presence of a tramway on the exit section 17. This equipment incorporates a coil ground sensor located on the track. When a tramway passes over this detector, the inductance of the coil is modified by the metallic masses of the tramway. This detector is capable of generating a presence detection signal of a trolley which is a binary signal taking the value zero when no trolley is detected on the output section and the unit value when a trolley is detected on the trunk. exit section.
    In this document, the term track equipment refers to both the sensor (antenna, axle counting device, etc.) or the actuator (motor to move the switch needle) and its low-level electronics. , which allows for example to digitize the analog signal delivered by a sensor or to apply a signal adapted to a supply of the actuator.
    Such a latching system operates in the following manner. At the approach of the switching section 10 from the upstream section 4, and knowing that it wishes for example to pass on the second downstream section 28, the driver triggers, through a suitable interface, the transmission, by the tramway, a control message requiring that the switch is placed in the position of engagement in deviated way.
    While the tram passes directly above the antenna, the latter picks up the control message and the communication equipment 40 transmits the corresponding command to the interlocking device 30.
    Upon receipt of the command, the interlock device 30 first verifies that certain security conditions are verified. In particular, the interlocking device 30 verifies that the switching section 10 is in the "not engaged" state. The non-switched state of the switching section is developed at each moment by the interlocking device 30 from the detection signals of the presence of a tramway generated on the one hand by the first upstream detection equipment and on the other hand. secondly by the second downstream detection equipment. The switching section will be said in the "not engaged" state if neither of these two detection devices detects the presence of a tramway. In all other cases, the switch section will be in the "on" state.
    If, at the time of receipt of the command issued by the tramway, the switching section 10 is indeed in the "not engaged" state, the interlocking device executes the command requiring that the switch be placed in the position in the deviated way.
    For this, the interlocking device 30 reserves the switching section 10 by placing it in the "on" state.
    Then, the engagement device 30 emits an actuation signal to the actuating equipment 42 so as to switch the switch 15 to the required position, in this case the deviated position. The interlocking equipment checks the current switching position of the switch and switches the switch needle, if necessary, to the deflected position for moving the tramway from the upstream section to the second downstream section. The actuating equipment 42 emits a confirmation signal from the switch-on position of the switch to the interlocking device 30.
    The latching device then transmits a signaling signal to signaling equipment 44 to indicate the current engagement position of the needle. Noting from the signposting equipment that the section was reserved for passage and that the switch is in the required interlocking position, the tram driver engages the streetcar on referrals.
    The interlocking device 30 then checks the following sequence of events: - that the presence detection signal of a tramway by the first detection equipment changes from the value zero to the value one, indicating that the front of the tramway advanced on the entrance section; - that the detection signal of the presence of a tramway by the second detection equipment changes from the value zero to the value one, indicating that the front of the tram has advanced on the exit section, the tramway being in to cross the switch; - that the detection signal of the presence of a tramway by the first detection equipment passes from the value one to zero, indicating that the rear of the tramway has left the input section; and - the detection signal of the presence of a tramway by the second detection equipment changes from the value one to zero, indicating that the rear of the tramway has left the exit section.
    Noting that the two upstream and downstream detection signals are again zero, the interlocking device 30 places the switching section 10 in the "not engaged" state.
    If, at the time of receipt of the command issued by the tramway, the switching section 10 is in the "on" state, the latching device 30 does not execute the command, but stores it in memory. It will try to run it periodically until the security constraints are checked.
    As long as the command is not executed, the signaling equipment 30 displays a signal by default indicating the driver not to advance the tramway on the switch section.
    This interlocking system is quite complex and requires a large number of track equipment.
    However, particularly in tram depots, many switches are planned over a relatively small area. The result is a need for simplification of interlocking systems to reduce cost, simplify installation and maintenance, and facilitate operation.
    For this purpose, the subject of the invention is an interlocking system for a switching section of a railway track situated between an upstream section and first and second independent downstream sections, the switching section comprising an inlet section. , a switch, and an output section, the system comprising an interlocking device and a plurality of track equipment located along the switch section and connected to the interlocking device, characterized in that the plurality of track equipment comprises: equipment for actuating the switch in a first position or a second interlocking position; signaling equipment at the turnout and showing a state of the switch section and a switch-on position; and a railroad vehicle presence detection equipment equipping the output section and capable of generating a detection signal, the detection equipment comprising a coil-type detector, the interlocking system being devoid of a detection device. detection of the presence of vehicle upstream of the switch.
    According to particular embodiments, the interlocking system comprises one or more of the following characteristics, taken separately or in any technically possible combination: the interlocking device comprises a radio communication module allowing the exchange of messages with a module of radiocommunication on board rail vehicles authorized to operate on the switch section. the interlocking device is able to reject a control message from the switch emitted by a railway vehicle, when the command contained in said message can not be executed immediately, the radiocommunication module of the railway vehicle repeating the transmission of the message of command until the corresponding command is executed. the engagement device is devoid of means for storing a command that can not be executed immediately, or processing means commands that have been rejected and stored. the interlocking device updates an interlocking state of the switching section only from the current value of the interlock state and the values of the detection signal generated by the presence detection equipment of a vehicle, located downstream of the switch. the plurality of track equipment further comprises a manual interlocking control panel connected to the interlock device, the interlocking device being clean, upon receipt of a command to change the interlocking position of the switch generated from said panel, to emit an actuation signal to the switch actuating equipment. the system further comprises a second equipment for detecting the presence of a railway vehicle comprising a coil mass detector and installed downstream of the detection equipment. The invention also relates to a method of using the preceding interlocking system, comprising the steps of: periodically updating, by an interlocking device, the state of a switching section from a current state of the switching section and the signal generated by a detection equipment; verifying that a command, transmitted from a tramway and received by the interlock device, and requesting that the switch be placed in a required interlocking position, can be executed; executing the accepted command so as to place a pointer needle in the required latching position, an actuating equipment emitting a confirmation signal of the current latching position of the switch to the latching device; modifying, by the interlocking device, the state of the switching section towards the "switched on" state; transmit a signaling signal to the signaling equipment to display the current switching position of the switch.
    Preferably, the step of updating the state of the switching section consists of checking whether the current state is the "on" state or the "non-on" state and, in the case where the current state is the "engaged" state, to check if the detection equipment detects the presence of a tramway and then detects the absence of a tramway, if the switch section passing in the state "Not engaged".
    More preferably, the step of verifying that the received command can be executed consists of checking the current value of the state of the switching section, the command being rejected when the switching section is in the state " engaged, "and. possibly, the current value of the detection signal generated by the detection equipment, the command being rejected when the detection equipment detects the presence of a tramway. The invention and its advantages will be better understood on reading the detailed description which follows of a particular embodiment, this embodiment being given solely by way of non-limiting example. This description is made with reference to the accompanying drawings, in which: - Figure 1 is a schematic representation of a latching system according to the state of the art; FIG. 2 is a schematic representation of a simplified interlocking system according to the invention; and FIG. 3 is a block representation of the operating method of the interlocking system of FIG.
    Referring now to Figure 2, a preferred embodiment of an interlocking system 101 according to the invention will be presented in detail.
    As in the state of the art, the system 101 equips a railway 2 having a switch. This channel 2 comprises successively an upstream section 4, a switching section 10 and first and second downstream sections 26 and 28. The switching section 10 comprises an input section 14 whose input corresponds to the output of FIG. the upstream section 4, the switch 15 proper, and an outlet section 17, the output of which is common to the first and second downstream sections 28 and 26.
    The system 101 includes an interlocking device 130 and a plurality of track equipment implanted along the track.
    This plurality of devices comprises at least: an actuating equipment 42 making it possible to place the switch 15 either in the position of engagement in deviated way, or in the position of engagement in the right lane; - Signaling equipment 44, placed at the right of the switch 15 to visually indicate to the driver of the tramway if the switching section 10 is in the "engaged" state or in the "not engaged"> > and when in the "unplugged" state, the current engagement position of the switch 15; and, detection equipment 46 for the presence of a tramway on the output section 17. This equipment comprises a coil mass detector. When a tramway passes over this detector, the inductance of the coil is modified by the metallic masses of the tramway. This equipment is capable of generating a presence detection signal of a tramway which is a binary signal taking the value zero when no tramway is detected on the output section 17 and the value one when a tramway is detected on the exit section.
    The interlocking device 130 is, for example, constituted by a computer rather than by a relay type automaton integrating a plurality of switches. This computer comprises calculation means, such as a processor 132, and storage means, such as a random access memory 134, the storage means storing computer program instructions adapted to be executed by the processor 132.
    The device 130 also comprises a plurality of input / output interfaces 142, 144 and 146, to which the different equipment of the plurality of channel equipment are connected.
    Preferably, the device 12 is also equipped with a radiocommunication module 150 allowing the exchange of messages between a tramway and the interlocking device 130, instead of a short-distance communication equipment of the type comprising an antenna along the way. Tramway T is therefore also equipped with a radiocommunication module 151 for the establishment of a temporary wireless link with module 150. For example a connection according to the WiFi protocol can be implemented.
    The device 130 comprises a communication bus 160 connecting the different components.
    The device 130 is therefore programmed differently to take into account this minimum set of track equipment and peripherals. The device 130 is programmed to implement the operating method which will now be described with reference to FIG.
    The operating method 200 comprises a step 210, during which the device 130 periodically updates the state of the switching section 10 according to a current state of the switching section 10 and the signal generated by detection equipment 46 only. The device 130 checks in particular whether the current state is the "engaged" state or the "not engaged" state and, in the case where the current state is the "engaged" state, if the equipment detection 46 detects or not the presence of a tram.
    More specifically, if the current state is the "engaged" state and if the detection equipment 46 detects the presence of a tramway followed by the absence of a tramway, the switching section 10 passes into the state "not engaged".
    Otherwise, the switching section 10 remains in the "on" state.
    If the current state is the state "not engaged", the device 130 waits for the reception of a command message for the switching on of the switch 15. At step 220, when the section is approaching referral 10 from the upstream section 4, and knowing that he wishes for example to pass on the second downstream section 28, the driver of the tram triggers, through a suitable interface, the transmission, by the radiocommunication module 151 embedded on board the tramway, a control message requiring that the switch 15 is placed in the position of engagement in deviated way.
    When, in step 230, the radio communication module 150 of the device 130 receives the command message for the switching on of the switch 15, it extracts the command from it and transmits it to the processor 132 of the device 130. At the step 240, the device 130 verifies that the received command can be executed.
    This check consists of checking the current value of the state of section 10.
    If the switching section 10 is in the "on" state, the device 130 rejects the command and transmits, in step 250, to the tramway a refused control message.
    Advantageously, this verification also consists in checking the value of the signal generated by the detection equipment 46. If the detection equipment 46 detects the presence of a tramway, the device 130 rejects the command and transmits, at the step 250 , towards the tramway T, a command message refused.
    Alternatively other additional security conditions may be verified in step 250 by the device 130, to determine whether the received command can be executed.
    The radiocommunication module 151 on board the tramway is then invited to reissue the control message regularly until the command is accepted by the device 130.
    When the device 130 accepts the command, it executes it immediately.
    For this, in step 260, it applies an actuation signal to the actuating equipment 42 so as to place the needle of the switch 15 in the engagement position required by the command received from the tram. In step 270, the equipment 42 checks the current position of the switch and switches if necessary it in the required position, in this case the deflected position to move the tram from the upstream section 4 to the second downstream section 28. The actuating equipment 42 transmits a confirmation signal from the current position of the switch 15 to the interlocking device 130. In the step 280, the device 130 modifies the state of the switch section to the "on" state. In step 290, the device 130 transmits a signaling signal to the signaling equipment so that it displays the current engagement position in which the switch 15 is located so that the driver of the the tramway is informed and can check that its order has been taken into account and that the switch is in the position adapted to the desired movement.
    Then at step 300, the tram T advances on the switching section 10, first on the input section 14, then the switch 15 and finally on the output section 17. At this time, the detection equipment 46 of the presence of a tram generates a detection signal taking the value one (detection of the presence of a tram).
    The tram continues its journey and returns to the second downstream section 28.
    When the rear of the tram has left the exit section 17, the detection equipment 46 generates a detection signal again taking the value zero (detection of the absence of tram). In step 310, noting the change of the value of the detection signal from zero to one, then from one to zero, the device 130 releases the switching section 10 by changing the state thereof and by replacing it at the value "not engaged". Those skilled in the art will therefore find that the interlocking system described above has a simplified structure compared to a system according to the state of the art, since it only has one single presence detection equipment. a tramway.
    In addition, in the particularly advantageous embodiment variant, in which the communication between the tramway and the interlocking device is effected by means of a radiocommunication link instead of using a near-field communication device, the communication device The trigger requests the tram to repeat the command message when it has been rejected, instead of saving the rejected command and attempting to execute it later. It is therefore possible to simplify the logic implemented by the interlocking device, the device no longer having to memorize a command that would not have been executed immediately or to have a loop allowing the account to be taken into account. stored commands and possibly a priority management mechanism between the rejected orders and the new orders received.
    Alternatively, as shown in dashed lines in FIG. 2, and in a known manner, the system may be equipped with a manual control board 48 for engagement. This is a board that is placed near the track and can be manually operated by an operator to change the switch engagement position. This panel is connected by a suitable interface 148 to the interlocking device and constitutes additional track equipment.
    When actuating a button provided on this table, the device 130 immediately modifies the switching position of the switch. In the state of the art, when a manual interlocking command is received by the interlocking device, the latter first checks whether one or the other of the first and second detection equipment transmits a detection signal. of value one, that is to say of detection of the presence of a tramway.
    It is not certain that the interlocking system that has just been presented can meet all the safety constraints imposed by a particular existing tram line, in particular the tramway lines in their portion of passenger transport by opposition to the deposit portions. However, it is certain that the present system responds to reduced safety conditions, such as can be found on the deposition portions, on which vehicles travel at a reduced speed and do not embark passengers.
    For implantation along the track so as to meet the safety criteria associated with the transport of passengers, it is envisaged to add to the interlocking system described above a second detection equipment incorporating a coil mass detector. and to implant it downstream of the device 46.
