Description

Technical Field

[0001] The invention relates to the field of shooting, and in particular to a high-precision conductive target plate. Background Art

[0002] When shooting with pistols and rifles, the military and police forces often use a conductive target plate with an embedded conductive aluminum foil. Usually two layers of conductive aluminum foil are used to provide level signals. The conductive aluminum foil is hard and inconvenient to process. It is mainly used to realize whether the projectile hits. At the same time, the perforated part of the aluminum foil will open backwards, and it is easy to form adhesion between the two layers, which will cause the target to be unable to be reported normally. The average number of bullets received by the target surface is no more than 2,000. Another type of conductive target plate that uses conductive cloth to provide area and direction is difficult to achieve high-precision reporting (providing the location of the specific impact point). In traditional conductive medium target reporting equipment, the power supply and data transmission at the end are transmitted in the form of wires. When the wires are hit by bullets or fragments, they cannot be used immediately. It takes an average of more than 10 minutes to replace the wires. Summary of the invention

The criss-cross conductive areas are used to meet the high-precision target reporting requirements of less than 5mm. At present, the diameter of the bullets commonly used by our military and police is above 5.8mm, ensuring that the target reporting accuracy is less than one bullet diameter; the single-chip microcomputer above MSP430 is used to realize the coordinate solution, as well as the solution of the number of target rings and the direction, and the solution speed is less than 0.01S; the fan blades located at the lower end of the target rod and the generator located at the upper end of the target rod are used for wind power generation to solve the problem of the fragility of the conductive wire.

[0104] It also comprises a longitudinal coding layer, wherein the longitudinal coding layer is a conductive cloth divided into a plurality of longitudinal regions.

[0105] It also comprises a transverse coding layer, wherein the transverse coding layer is a conductive cloth divided into a plurality of transverse areas.

[0106] The longitudinal coding layer and the transverse coding layer are arranged at certain intervals to achieve the positioning of the longitudinal and transverse areas.

[0107] The decoder performs rapid loop number and direction calculation on the conductive fabric in the vertical and horizontal areas to achieve a high precision guarantee of ≤5mm.

[0108] Position determination:

[0109] like Figure 3 As shown in the figure, a longitudinal coding layer is designed. Each conductive area is 50mm wide and 50mm apart, and each impact point is located within the longitudinal range of 50mm. There are 5 longitudinal coding layers of the same type, and they are translated to the right by 10mm in sequence, and the longitudinal position encoding is performed left and right in sequence. When the impact triggers multiple coded information, it is processed based on the principle of being close to the center of the 10 rings as valid information, and the regional information with a longitudinal deviation of ≤5mm is realized.

[0110] like Figure 6 The institute designs a transverse coding layer. Each conductive area is 50mm wide and 50mm apart, and each impact point is located within a 50mm range in the longitudinal direction. Each effective conductive area is 50mm wide and 50mm apart. There are 5 transverse coding layers in total, which are evenly distributed up and down at intervals of 10mm, and the longitudinal position is encoded in sequence up and down. When the impact triggers multiple coded information, it is processed based on the principle of being close to the center of the 10 rings as valid information, and the regional information with a lateral deviation of ≤5mm is achieved.
