Design of Multi-channel Parallel Test System Based on 485 Bus

In order to solve the problems of automatization and low efficiency in the circuit test of the trial product of a certain type of fuze in the scientific research stage, as well as the application requirements of batch testing in the later production stage, a multi-channel parallel test system based on the 485 bus was designed. The parallel test system can realize the parallel test of 100 fuze circuits at a time, and on the premise of ensuring the test accuracy, the automation degree and efficiency of the fuze circuit test are improved.
