- control means 15 includes an activity duration control device 20.
- This device includes a memory 22, inside of which is introduced (for example with a keyboard 23) a duration of activity for exercise mines.
- the clock is set at the start of the exercise so that time 0 corresponds to the supposed placement of mines.
- the solid state relay 24 is in the normally closed position. So when a mine is detected by the variation 14, the signaling means are controlled like before.
- comparator 25 causes the static relay 24 to open.
- the signaling means are not more actuated when the vehicle (or the individual) meets a mine of exercise.
- the activity duration control system 20 is carried out using the microprocessor which manages the operation of the control means 15.
- Figure 7 shows a simplified electrical diagram of a simulation device according to a third mode of realization of the invention.
- the detection means contained in this device have two generators 13a and 13b, each supplying a different active oscillating circuit formed by an inductor (lla, llb) and a capacity (12a, 12b). Each active circuit is tuned to a different frequency.
- This simulation device is implemented with exercise mines with a passive oscillating circuit 5 of the type of the one which is shown schematically in figure 7.
- This circuit oscillating comprises an inductance 6 at the terminals of which two circuit branches are mounted, each branch being formed by a capacity (7a, 7b) and a fuse (19a, 19b) mounted in series.
- the active oscillating circuit (11a, 12a, 13a) will be chosen as that it be tuned to the resonant frequency Fr1.
- the active oscillating circuit (llb, 12b, 13b) will be chosen as that it be tuned to this resonance frequency Fr2.
- the variation detectors 14a and 14b are connected by means control 15 which in this embodiment comprises a duration of activity control device 20.
- This device comprises a clock 21 and two memories or registers 22a, 22b.
- Each memory is intended to receive a number representative of a theoretical duration of mine activity of exercise used.
- the memory 22a will receive a duration of activity which will be associated with an exercise mine whose passive circuit has the resonance frequency Fr1, the memory 22b receives a duration of activity which is associated with a mine whose passive circuit at the resonance frequency Fr2.
- the memories are programmed by means of the keyboard 23 or a serial link.
- Switching means for example static relays 26a, 26b
- Each means is found in normally open state. It is controlled by the detector variation 14a, 14b associated. Detection of a mine exercise of a certain type thus causing the tilting relay 26a, 26b associated with this type of mine.
- An OR logic gate 27 groups the memory outputs 22a and 22b downstream of the static relays 26a, 26b. The exit of this door gives the contents of memory 22a or 22b which corresponds to the mine detected by the oscillating circuits assets. This content is compared (comparator 25) to the value of time provided by the clock 21.
- Static relay 24 will be here in a normal state open. When the life of the detected mine (T1 or T2) is not exceeded, the static relay 24 closes and causes actuation of the signaling means 16,18.
- a relay closing time will then be provided static 24, to allow the vehicle to be moved away from the mine considered so as to allow consideration by the vehicle of another type of mine whose duration of activity is not yet over.
- We can replace such delay by detecting the distance from the circuit oscillating previously detected (return to the initial state of the active oscillating circuit).
- the activity duration control system 20 will still be achieved using the microprocessor which manages the operation of the control means 15.
- the control means can transmit as before by the antenna 17 parameters relating to the detected mine, for example the contact details of the bearer during the meeting of the mine, the nature of the mine encountered (frequency of passive circuit or code associated with this frequency). This transmission can be ordered, only the duration of activity of the mine either passed or not. Information relating to nature of the mine could for example be taken at the exit from the door OR 27.
- This embodiment of the invention has been described with a passive circuit with two capacity / fuse branches connected to the terminals of the inductor and with a device simulation consisting of two active oscillating circuits. he it is of course possible to define a passive circuit, carried by a label stuck on the mine, and with several capacity / fuse branches. Such a passive circuit could have as many different resonant frequencies as it has branches carrying a capacity. We will choose one of these frequencies by blowing a number of fuses.
- a programming device which includes a circuit oscillating active (similar to that used on the vehicle) but it is possible to vary the frequency and the amplitude of the signal transmitted.
- This active circuit allows everything first determine the oscillation frequency of the circuit passive. Once the circuit has been tuned to this frequency, the operator operates a switch which controls generating a power signal at this frequency oscillation. As previously described, this signal blows the fuse in the branch having the maximum value capacity, thereby changing the natural frequency of the passive circuit.
- Resonant frequency search operations then of power signal generation are repeated as much as many times as necessary to melt different fuses of the passive circuit and give it the natural frequency desired.
- the programming of the passive circuit by mechanically cutting the branches which must be excluded from the passive resonant circuit.
- the simulation device carried by the vehicle (or by an individual) will then have three active circuits tuned on these three possible frequencies.
- FIG. 7 describes an embodiment in which mines could have different durations of activity, each duration being associated with a different frequency from passive circuit.
- the simulation device used in this case is close from that described with reference to FIG. 7. It differs therefrom what the outputs of memories 22a, 22b after the relays 26a and 26b are not compared to the clock signal (suppression comparator 25 and OR gate 27).
- "mine type” information (provided for example by memories 22a, 22b) is used to control the means of signage 16.18. These means may be different for each type of mine.
- An "anti-tank” mine causing by example vehicle stop and an anti-personnel mine just a beep. As before, the means can transmit the contact details of the vehicle and the characteristics of the mine encountered.
- Such an embodiment is particularly advantageous since it allows with a single passive circuit model to simulate different types of mines.
- Figure 8 shows a simplified electrical diagram of the simulation device according to a fourth mode of realization of the invention.
- This device is also shown associated with a circuit passive 5 with at least two capacity / fuse branches placed in parallel across the inductor 6.
- the active circuit differs from the circuits described above in that the detection means comprise a generator 28 frequency swept connected to a transmitting coil 29.
- the sweep frequency generators are well known to humans of career. They provide a signal whose frequency varies periodically between two fixed limits.
- Such generators are commonly used in electronic for example to adjust the tuned circuits radio or television receivers.
- the generator is coupled as before to a detector variation 14, itself connected to the control means 15.
- These include a computer 30 which receives the signal from the variation detector (link 32) and the signal supplied by the generator (link 31).
- the computer thus determines the frequency value F emitted by generator 28 and for which a coupling with passive circuit 5 has been detected.
- the static relay 24 will for example be normally open and its closing will be controlled by the comparator 25 if the duration of mine activity has not expired.
- Figure 9 shows a simulation device according to a fifth embodiment of the invention.
- the means of detection comprise, on the one hand a generator 36 containing an active oscillating circuit and coupled to a transmitting coil 37, and on the other hand a take-up reel 41 connected to a receiving amplifier circuit 40.
- a bandpass filter 38 receives the signals transmitted by the generator 36 and those received and amplified by circuit 40. It isolates in the signal received by the coil 41 the lines which are due to the magnetic field emitted by the coil 37, this in order to avoid disturbances due to outdoor fields.
- the filter could for example be a synchronous filter whose the principle is well known to those skilled in the art.
- the filter is connected to a variation detector 14 which is itself connected to a control means 15 which can be made according to any of the forms described previously.
- the field emitted by the coil 37 When the device passes near a mine according to the invention carrying a passive circuit 5, the field emitted by the coil 37 generates a current in the passive circuit 5.
- This current causes a change in the magnetic field at near the passive circuit. This change results in a variation of the amplitude of the voltage across the take-up reel 41. This variation is detected by the detector 14 and it causes a mine to be taken into account by the control means 15 and the possible triggering signaling means 16,18.
- Another advantage of this variant is that it allows place the take-up reel and the take-up reel at different places.
- the simulation device advantageously place the two coils under the vehicle at the level of a front part of it, each coil being arranged in the vicinity of a different side of the vehicle.
- the coils are preferably oriented such that the emitting coil 37 emits its field magnetic towards the ground under the vehicle, the take-up reel 41 being oriented so as to receive a magnetic flux maximum of the soil.
- the device according to the invention thus provides a simulation even closer to reality operational.
- generator 36 a generator frequency swept (combination of this embodiment with that of figure 8).
- the invention also relates to a device for simulation of a demining machine. Such a device is described with reference to Figure 9.
- This simulation device is implemented with exercise mines according to the invention, that is to say equipped with of a passive oscillating circuit comprising one or more capacities (7a, 7b).
- the generator comprises a generator 13 coupled to a transmitting coil 29.
- the generator frequency can advantageously be adjusted by the control means 15 (connection 34).
- the generator is still connected to a variation detector 14 whose output signal is applied to a computer 30 of control means 15.
- the memories or registers 22a, 22b each receive a number representative of a duration theoretical activity of the exercise mine used.
- the computer checks whether a detected mine is active or no and it possibly controls signaling means 16a, 16b when the mine is "active".
- the intensity of the signal emitted by the generator will be chosen sufficient to melt the worn fuse (s) by the passive circuit. Practically although the intensity is permanently strong enough to neutralize circuits passive, approaching such a circuit will cause a disturbance of the transmitted signal which is sufficient to ensure a detection and allow the emission of a signal (by sound example) informing of the destruction of a mine.
