Design of a Multi-channel and Multi-parameter Fuze Test System

Abstract

The fuze is used as the detonation control system for ammunition to directly determine the damage performance of the weapon system. During the flight of the long-range rocket, the normal communication between the fuze and the guidance cabin directly affects whether the fuze can work normally. This paper designs a test system for fuze self-state information detection and data reception and feedback with the guidance cabin. The system is based on two C8051F310 single-chip microcomputers to record the flight status of the fuze pin, detonator and other parameters, through the RS422 chip signal modulation to complete the communication between the test system and the guidance cabin. This paper expounds the basic principle of the fuze test system, designs the test system circuit and program, and performs cross-linking of two MCU information according to strict timing. The system realizes multi-channel and multi-test point data test under low power consumption conditions, and provides data support for fuze design improvement.
