Self-propelled Artillery Aimer Training Evaluation System Design And Implementation

Modern military struggle preparation, all kinds of high technology of new typeweapons and equipment of Fielding troops, making to enhance our national defensecapabilities. But, how will the new weapons and equipment quickly into fightingcapacity is a significant problem facing the forces, the training evaluation is apeacetime army to improve training quality, skilled in weapon equipment’s importantway.Gunner training evaluation system is mainly composed by sensor acquisitionsystem, wireless transmission the receiving system, voice system and trainingevaluation system, can complete on self-propelled guns aimed at hand trainingassessment. System by using high precision displacement sensor, the use of a magnetis installed on the self-propelled guns, a minute to complete tear open outfit, andcalculations and analyses the influence of terrain tilt to shoot Angle and the directionof impact, greatly improve the accuracy of the system; Using wireless transmissiondevice and the built-in lithium battery, the artillery side does not plugged into a powersupply, avoid the large bundle of cumbersome wires erection. Training evaluationsystem, through the voice system password instructions, and receiving artillerydetermined the yuan, according to army military training assessment outline ofevaluation results.This paper mainly to solve the problem are as follows:1, the displacement sensor with high precision, can be installed on theself-propelled guns for aimer training, implements the live-fire training assessment;According to the structural characteristics of self-propelled guns, using powerfulmagnets to choose the right position to install remove displacement sensor, can becompleted within one minute tear open outfit, use very convenient operation, greatlyimproving the training effect.2, pull type displacement sensor in the go online using the device structure,ensures that each pull out and retract, is the only line of the coil position. In addition,the anchor adopted special stainless steel and plastic structure, tension deformation, toensure the repeatability of the system. 3, through calculation analysis terrain inclination to give shoot Angle and thedirection of the error analysis and correction of the self-propelled guns determinedinfluence each other between the markings and direction, in addition, the systemacquisition is cannon gun tube height and direction of momentum, solved the artilleryempty back to bring the error of the timing gear, thus accurate get cannon gun tubeand the Angle on the horizontal direction and height, and use that to determine workprecision aimer, truly satisfied the new outline of aimer training assessmentrequirements.4, with the method of wireless transmission, the system power supply, solve thefield under the condition of wire trapped but cannot be connected to the mains,erection problems, using ISM frequency band, the frequency of430m, the obstacleshave strong diffraction function. Wireless data transmission module USEShigh-performance FEC forward error correction technology, with stronganti-interference ability. The voice system in the form of password notification examand enhance the practicability of the system.
