Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a land mine detection system, and more particularly to a land mine detection system for detecting a land mine which is embedded in a complex manner by combining a metal detection system and an underground radar device.

[0002]

2. Description of the Related Art In conventional landmine detection, a metal detector using a magnetic method is mainly used, and in recent years, it has become possible to detect even a metal as large as a needle that is buried.

[0003]

In the conventional landmine exploration method using a metal detector, when the metal detector shows a reaction, the reactant is buried in a region substantially corresponding to the detection coil portion of the metal detector. It can be understood that the land mines can be removed within a few meters at most on the day because the work of carefully locating the buried position of the reactants is performed while inserting the probe and inserting the probe.

An object of the invention according to the present application is to provide a land mine detection system capable of quickly and clearly finding a buried position of a land mine.

[0005]

The structure for achieving the object of the invention according to the present application is a metal detector in which a detection coil portion is provided at a tip portion of a support arm, and a detection area of the detection coil portion of the metal detector. In the landmine detection system, the ground mining radar device has an electromagnetic wave irradiation area, and the ground surface radar device has a display unit for displaying a situation in the ground in the irradiation area.

In the above structure, the ground radar device is detachably mounted on the metal detector.

The ground-penetrating radar device having the above-mentioned structure is characterized in that a plurality of sensors are arranged in an array.

1 is a diagram showing a schematic configuration of a land mine detection system according to the present invention, and FIG. 2 is a diagram showing an outline of the ground radar device of FIG.

Reference numeral 1 denotes a metal detector, which has a ring-shaped detection coil 3 attached to the tip of a support arm 2, and magnetically detects if a metal is buried in the ground below the detection coil 3. Then, the signal sound amplified by the amplifier (not shown) is heard through the headphones (not shown), and it is determined whether or not the metal is buried. As long as the land mines that can be detected have a small amount of metal, it is possible to sufficiently detect the metal itself even if it is a plastic landmine. In addition,
The amplifier and the power supply battery may be separately connected to the detection coil 3 and the signal line as a unit, or may be internally provided in the support arm 2.

Reference numeral 4 is an underground radar device. For example, a sensor 5 in which a transmitting circuit, a transmitting / receiving antenna, a receiving circuit and the like for generating electromagnetic waves are highly integrated in a case 5 having a size of a cigarette box. The sensors are arranged in an array, and each sensor receives electromagnetic waves emitted toward the ground through a receiving antenna of each sensor and is received by a receiving circuit. Therefore, by adjusting the number of arranged sensors or making them staggered, one sensor 5
It becomes possible to handle as one pixel, and by performing image processing by a microcomputer or the like, a plane image can be displayed on the display 6 such as a liquid crystal display, and also a plane image at a desired depth can be obtained. it can. Further, when the size of the buried object detected by one sensor 5 exceeds a predetermined size, a light emitting element such as an LED corresponding to the sensor is turned on, and the set of the light emitting elements that are turned on produces a contour of the buried object. The position can be displayed.

Therefore, when the metal detector 1 shows a reaction, when an electromagnetic wave is struck by the ground radar device 4 toward the ground surface in the region where the reaction has occurred, what shape the object is embedded in and at which position. It is possible to surely determine whether there is an eye. For this reason, the displayed buried position is searched with a probe rod or the like, and if this is a land mine, the removal work can be immediately performed, so that the land mine can be removed safely and quickly.

Further, the subsurface radar device 4 can be mounted on an existing metal detector if the sensor array part in which a plurality of sensors 5 are arranged in an array or the display can be detached from a support arm or the like. You can

Further, the power source of the underground radar device may be prepared as a battery separately from the metal detector, but the power source battery of the metal detector may be used.

[0014]

According to the invention of the present application, when the metal detector reacts, the underground condition in the area where the underground radar device reacts can be visually grasped, so that it can be safely judged whether or not it is a landmine. And it can be done quickly. Further, by making the underground radar device removable to the metal detector, the existing metal detector can be used.
