Technical Field

The invention relates to the field of live-fire practice training, in particular to a double-conductive-layer target plate for live-fire practice training.

Background

The conductive target board is a target board which can conduct a conductive layer through a shot target board to form a pulse signal to realize automatic target reporting. The main working principle is that the target plate is composed of at least two conductive layers and an insulating layer between the conductive layers, when a metal shot penetrates through the target plate, the two conductive layers of the target plate are conducted, pulse signals are formed on corresponding signal lines, and shooting signals of the target plate are automatically captured. Description of the automated design of conductive targets in articles such as "electronic measurement technology" design and implementation of an automatic target scoring system "in 5 th month 5 of 2008.

At present, in the engineering and production processes of the conductive target plate, aiming at the requirement of combining tactical training and assessment training of troops, the conductive target plate needs to simultaneously realize simultaneous target reporting of shooting chest rings and shooting directions. There are three ways to implement products on the market:

1. each chest ring conducting layer is cut according to the shape of the chest ring and forms a loop with a complete grounding conducting layer to be used as a chest ring target reporting unit. The azimuth target-reporting unit is designed in the same way, and the chest ring and the azimuth target-reporting unit are bonded in a series connection mode, so that simultaneous target-reporting of the chest ring and the azimuth is realized.

2. The chest ring layer and the azimuth layer share the same complete grounding conductive layer, the metal shot is sequentially conducted with the chest ring layer and the grounding layer, and the grounding layer is conducted with the azimuth layer, so that the chest ring and the azimuth target plate are simultaneously realized. Compared with the former mode, the method can reduce one grounding conductive layer and realize cost saving.

3. The chest ring layer is cut according to the direction, so that the chest ring layer is divided into a chest ring and small direction blocks, and a loop is formed by the chest ring layer and the complete grounding layer. According to the mode, the chest ring position layers are integrated, and the chest ring position is reported simultaneously by adopting two layers of conductive materials. However, in this method, the number of the conductive layers in the chest ring direction is too large, so that the service life of the target plate is greatly influenced.

In summary, in the prior art, the processing method adopted at present is that every two conductive materials are conducted, and only one conducting signal is output. When the chest ring and the azimuth are separately arranged, at least three conductive layers are needed to form a target scoring unit, and when the chest ring and the azimuth are integrally arranged, the elastic life of the conductive layer in the chest ring azimuth is low, and engineering is difficult to economically realize.
