Design and realization of wireless communication interface of portable single vehicle simulation tester

In order to solve the problems of complex circuit debugging and inconvenient operation, wireless communication technology is adopted and the USR-WIFI232-B2 module is used to complete the data transmission and reception between the single vehicle simulation tester and the upper computer. The hardware circuit and software flow of the portable single vehicle simulation tester are described, the wireless communication module is configured, and the laboratory test and on-site debugging are completed. It greatly facilitates the operation of the workers and improves the debugging efficiency.
