Research on Acquisition Technology of Artillery muzzle velocity reduction value Based on Proteus

A signal acquisition system for the number of projectiles in the fire control system based on Proteus's AT89C51 single-chip microcomputer is proposed. Take 89C51 microcontroller as the control core, Tested and analyzed the projectile signal of a tank gun with its rich peripheral interface and I/O resources. Then, the amount of initial velocity reduction is determined according to the number of projectiles of each type of artillery. The system has completed the collection, storage and calculation of a certain type of tank gun projectile signal, and has an interface for communication with the host computer. It can complete the information transmission with the fire control computer, and has the advantages of small size, simple structure and easy implementation. It has certain application value for the automatic correction of the initial velocity reduction of tank guns. It also provides some reference for the system design of the military department.
