DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The technical scope of the present invention is that of exercise mines and devices enabling the simulation of the action of a mine.
Simulation devices are known which implement complicated means to materialize the action of a mine on a vehicle or person.
Therefore, more often than not, the mine is not present on the ground, but occupies a theoretical assigned position by a check point which is radio linked to receivers carried on the vehicles and/or persons.
The position of the latter is known by means such as global positioning systems (commonly termed GPS) or inertial navigation plates. The check point compares the actual position of the vehicles and individuals with that of the mines and sends them a signal when one of them triggers a mine.
Such devices are complicated to implement. They necessitate the use of positioning means which may not be accurate enough and involve onerous computation means. In practice, they can only be implemented on specially prepared areas of land which are equipped with suitable infrastructures.
These devices are also incomplete since they do not allow the actual positioning of a mine field to be simulated.
Exercise mines are known elsewhere which comprise inoffensive pyrotechnic charges (smoke-generating, noise-generating) which are triggered by the approach of a vehicle or person. The advantage of such mines is that they enable the realistic simulation of the activation of a real mine. However, they are expensive as they involve the use of a pyrotechnic charge and detection means for a real mine.
Moreover, although their effect is theoretically danger-free, such mines can not be left in the ground undetonated. Their use therefore necessitates a long and costly operation to demine the area of land after the training exercise.
SUMMARY OF THE INVENTION
The aim of the invention is to solve the above problems by proposing, on the one hand, an inert exercise mine at a low cost but which enables the realistic simulation of the effect of a real mine, and on the other, a device to simulate the action of the mine and which implements such an exercise mine.
The invention also proposes a device to program such an exercise mine which enables a given exercise mine to be given different detection characteristics.
The invention lastly proposes a device to simulate a demining operation, a device which also implements an exercise mine according to the invention.
According to the invention, an exercise mine it comprises at least one passive oscillating circuit tuned to a certain frequency, and a circuit designed to be detected by at least one active oscillating circuit carried by a person or by a vehicle.
The passive oscillating circuit will comprise at least one fuse or destructible part.
The passive oscillating circuit can comprise at least one inductive resistor whose terminals are connected to at least two circuit arms, each arm being formed of a capacitance and a fuse or destructible part connected in series.
The passive oscillating circuit can be made in the form of a rigid printed circuit attached to the mine. It can also be made in the form of a flexible printed circuit fastened to the mine. The passive oscillating circuit is formed of a serigraph of conductive paint.
This serigraph can be carried on a label stuck onto the mine.
A further subject of the invention is a device to program such a mine. Such a device it comprises an active oscillating circuit which generates a signal at an adjustable frequency and strength, an active circuit enabling the determination of the oscillation frequency of the passive circuit carried by the mine, and includes a switch controlling the generation of a power signal at this oscillation frequency, the signal designed to melt a fuse integral with the passive oscillating circuit of the mine.
The invention also relates to a device to simulate the action of a mine, the device it comprises means to detect at least one passive oscillating circuit carried by an exercise mine, the means including at least one active oscillatin
