    [0001] FIELD OF THE INVENTION The invention relates to the general field of portable electromagnetic metal detectors.
    [0002] Such detectors are mainly used for leisure, looking for coins, jewels, treasures, but also by professionals for demining, ballistics research, or the search for pollutant metal pipes or particles in industry and industry. food sector.
    [0003] BACKGROUND OF THE INVENTION - PRIOR ART A wide variety of metal detectors are commercially available, commonly used for research and discrimination of buried or masked metal objects by vegetation covering the ground. The metal detectors most commonly used, especially for leisure, operate in the frequency domain. They use the now well-known principle of phase measurement between a low-frequency alternating electromagnetic signal emitted by a coil powered by an electrical voltage, and the signal received by another coil close to the first. Other less common alternative technologies are also used, for example the pulsed induction type, which are no longer working in the frequency domain but in time. These metal detectors, qualified for the sake of clarity in the description of "common metal detectors" in the remainder of the text, are usually composed of 3 parts: a detection head, or detection disk, generally disposed in a plane, - a support rod, which may or may not be telescopic, at the end of which is mounted the detection head, - an electronic control unit which manages the switching on and off of the detector, which generates the electrical signal of excitation of the transmitting coil housed in the detection head and retrieves and analyzes the signal detected by the receiver coil and which signals to the operator via a display and an audible warning that an object has been detected in the field area covered by the sensing coil. The control box of the usual metal detectors is generally connected to the detection head by a wired connection which allows the transmission of the excitation signal to the coil which equips the detection head and the recovery, for exploitation, of the signal detected by the detection head. Very generally also, these detectors comprise an audio headphone headset that allows the electronic unit to transmit to the operator an audible signal when an object is detected. The buzzer present on the case can then be cut, for reasons of discretion in particular. Depending on the device considered, the control box can be fixed on the support rod. Alternatively, it can be configured to be worn on the belt or slung in a suitable case or bag. There is currently on the market of conventional metal detectors also equipped with a radio link enabling the control box to wirelessly transmit an audio detection signal to a headset equipped with a radio receiver. There are also on the market metal detectors equipped with multipoint radio links making it possible to dispense with any wired connection, the control box managing over all the elements of the detector described above by radio link. The multipoint radio link is also configured to allow the detection head to be controlled either by the control box, or, in the absence of the latter, by the operator's helmet. Such equipment is described in particular in the French patent published under the reference FR2916055 and owned by the applicant. This type of equipment has the advantage of a great modularity, insofar as the protocol that manages the radio links allows according to a configuration chosen by the operator, or implicitly determined by the elements of the detector in service at the moment. considered, to communicate the various elements (considered as subscribers on the radio link) with each other, so as to ensure the best possible ergonomics for the operator while still ensuring the main function of detection. In general, the usual detectors proposed on the market generally have a satisfactory sensitivity, so that as soon as one approaches an object of interest, they react by signaling to the operator by an optical or audible indication that an object has been detected in the area covered by the electromagnetic field established by the coil of the detection head.
    [0004] However, these detectors offer a very approximate target location, and do not allow to precisely target the position of the object. To access this object and seize it is usually obliged to leave the detector aside and clear, a little blind, the area where the object is presumed to be and, if necessary, to dig the ground.
    [0005] In such a context to facilitate this final phase of the recovery of the detected object, it can be used, to precisely locate the object, to a "pocket" detector, or pointer, having a small diameter detection head to the interior of which is placed a detection coil and dimensions comparable to those of a flashlight, which is moved above the presumptive zone while the vegetation and / or the ground layer are cleared which covers the object. Such a locating device, commonly called "pinpointer" according to its Anglo-Saxon name is of interest, because of its small size, to be easily moved closer to the field on the area determined by means of the main metal detector to which he is associated. Moreover, because of the geometry and dimensions of its electromagnetic head, it has the advantage of covering a narrow detection zone around the pointed direction, so that it offers a high location accuracy. This avoids, advantageously, to unnecessarily clear a too large area of land. For the sake of clarity following the presentation, such a proximity locator will be described as "pointer" in the text that follows, with reference to English terminology. There exist on the market different models of pointers which implement detection means similar in their operation to those used by conventional metal detectors, such as those described above. These pointers generally have a rudimentary user interface which is limited to a start-up indicator and has means for signaling the detection of a target to the operator, the action of which is summed up by the transmission of a signal. warning sound emitted by a buzzer, usually accompanied by the vibration of the wall of the device. Consequently, when for reasons of discretion with regard to the surroundings, the operator decides to cut off the sound emission produced by the buzzer, the detection of an object is only indicated by the vibration of the walls of the pointer. . However, unlike the signal emitted by the buzzer whose intensity can be modulated according to the intensity of the signal received, the vibration generated by the pointer only reports the intensity of the detected signal very approximately. The pointer is then of a more delicate use. The pointers also have independent operation independent of any other detection equipment. Consequently, in a context of searching for objects on a given area, a conventional detector, which acts as a main detector, is first used to detect the possible presence of objects. Then when the presence of an object is detected, a pointer is used to accurately determine where the object is located in the detection zone covered by the detector head of the main detector. The two devices are thus implemented independently of each other, so that when one or other of these detection devices is used alternately, attention must be paid to the operating disturbances. that these two devices can generate one vis-à-vis the other, if they are active simultaneously. In such a context, the operator is generally forced to deactivate one of the two detection means, either by disabling the detection signal produced by the main detector, not used at the instant in question, or by cutting off the detector. feeding of the latter. Thus, in all cases, when using its proximity locator, its pointer, the operator only has an isolated location device, without any possible functional interaction with the main detector 35 used to detect the near presence of an object. The pointer can not benefit from any of the features that can be offered by the latter, especially in the case where the main detector used is equipped with a radio link allowing some of its elements to exchange information, such as this is the case of metal detectors equipped with wireless-link headphones, or detectors equipped with a multipoint radio link, such as those mentioned previously. PRESENTATION OF THE INVENTION An object of the invention is to propose a metal object locating equipment comprising a proximity locator, or pointer, capable of operating at least partially integrated with a conventional metal detector having at least one metal detector. a radio link between its control box and an operator's helmet.

The pointer 11 includes, in known manner, an end 12 in which is housed the detection coil and a gripping zone 13, a handle, by which the operator holds the pointer 11 in hand, which body contains in particular the batteries that supply the pointer. On the handle 13 are placed means making it possible to use the pointer according to the invention as a conventional "Pinpointer", in particular an on / off button 14 making it possible to put the pointer under tension, as well as a buzzer emitting a signal. sound signaling to the operator the detection of an object, a signal whose sound level can be adjusted, by means of a level control 15 for example, and that means for the vibration of the handle 13 of the pointer, vibration intended in particular to alert the operator of the detection of an object in the case where the latter, for reasons of discretion in particular, decided to inhibit the sound signal. However, unlike commercially available devices, this pointer also includes control and control means associated with radio link communication means. These means, not visible in the figure, are preferably housed in the handle 13. It also comprises an operator interface, also housed at the level of the handle 13, which allows, after powering on the pointer 11, to activate the radio link. such that the pointer 11 can exchange information with a remote device having communication means compatible with those who equip it. This interface consists, for example, of one or more control buttons 17, 18 making it possible to access the various functionalities that can be implemented by the control and control means, as well as a display 16 allowing the user to operator to take cognizance of the different information delivered by the same means of control and control.
    [0008] The control and control means, as well as the means of communication associated with them, may, depending on the embodiment considered, be configured to perform more or less complex operations.
    [0009] Thus, for example, in a simple embodiment of the device according to the invention, the control and control means can be configured so as to ensure autonomous operation and operation of the pointer 11 and to transmit only, via of the radio link, a detection information which can for example take the form of a beep of a given duration or an acoustic signal whose duration corresponds to that during which the detection of an object takes place. Similarly, in another embodiment, the control and control means can be configured to also provide the transmission of status information which indicate for example the operating frequency of the pointer 11 or the state of charge batteries that feed it. Similarly, in another embodiment, the control and control means may be configured to also receive control information from a remote device, the on and off control of the control device. transmission of the pointer 11, or the control of its transmission frequency for example. Depending on the equipment with which the pointer 11 exchanges information, the radio link used is of a variable nature.
    [0010] It is preferably a link using a standard communication protocol, a Bluetooth TM link or a TM wifi link, for example. However, it may also be a link implementing a specific protocol, allowing the pointer 11 to communicate with the equipment or the system, a system setting radio communication different equipment within a private network for example. In addition to the pointer 11, as described in the preceding text, the device according to the invention may also comprise, in a particular configuration, illustrated in particular in FIG. 2, an operator helmet 21 equipped with radio communication means configured to be compatible , in terms of waveform and communication protocol, the radio communication means which equip the pointer 11. The helmet 21 may according to the case and according to the configuration of the pointer with which it is associated, simply dispose of means of communication. communication allowing it to receive by radio a detection beep emitted by the pointer, or have more sophisticated means of communication, associated with an appropriate user interface 22, allowing for example the operator to start or cut the excitation of the coil of the pointer 11, to inhibit the buzzer mounted on the latter or to control the frequency the excitation signal and display on a display 23 the operating configuration of the pointer 11. In this configuration, the operator thus has an autonomous set pointer - headset that allows him for example to inhibit the buzzer 15 of the pointer 11 so as to operate in a discrete manner, while receiving in the helmet 21, in the form of a beep of amplitude or variable repetition frequency, for example, the warning signal generated by the latter when a metal object is detected. In a particular embodiment, illustrated in FIG. 3, the operating helmet 21 may moreover comprise an audio input 24 enabling the operator to connect his headphones, by means of a cable 25, to the audio output of a given equipment, the control box 32 of a conventional metal detector 31 for example. It is then preferably provided with a switching control, a touch control or a switch control 26 as illustrated in FIG. 3, allowing the operator to select the sound source connected to the earphones of the headphones: the audio channel transmitted by the cable 25 or the radio link with the pointer 11. In such an embodiment the headset can also be configured to automatically inhibit the audio input from the moment it is in radio communication with the pointer 11. In this case, the reception of the detection signals that can come from the pointer 11 is by priority priority if it is running, except if the operator decides otherwise. In its configuration where it comprises both a pointer 11 and an operator's helmet 21, the device according to the invention can be used alone, independently of any other equipment, the sound signal characterizing the detection of an object then being transmitted to the user. operator by radio link rather than being issued by the buzzer that equips the pointer 11, so that the operator can conduct his research in any discretion, without disturbing his entourage. However, as illustrated in FIG. 4, the equipment according to the invention can advantageously be integrated into the operation of a larger system, such as a wireless metal detector 61 equipped with a multipoint radio link connecting the various elements. constituting the detector, provided that this connection is compatible with the radio link connecting the operator's helmet 21 to the pointer 11 of the locating equipment according to the invention.
    [0011] In such a mode of operation, the helmet 21 may be configured, as illustrated in FIG. 4, to replace the helmet normally used by the operator in the context of the implementation of the wireless metal detector 61. furthermore, be configured to substitute, in the context of a simplified mode of operation of the main metal detector 61, with the control box 62 and directly drive the detection disk 63 and the pointer 11, as illustrated by FIGS. and 6. Similarly, in one mode of operation, the pointer 11 may be configured, as illustrated in FIGS. 7 and 8, to substitute for the control box 62 and manage both the operation of the detection disk 63 and that of its own detection coil, for example by operating alternately either the detection disc 63 or its detection coil, or by processing only the detection signals transmitted by one or the other of the detection heads according to the choice of the operator 60. The detection information from the detection coil of the pointer 11 or the detection disk 63 of the metal detector 61 are then, by example, managed by the control and control means of the pointer 11 and transmitted to the headset 21 in the form of a beep. Similarly, the configuration information of all the equipment is then managed by the control and control means of the pointer 11 and displayed at the display 16 which equips the latter.
