In order to solve the defects of the low level of intelligence, poor scalability and low communication rate of the point-to-point protocol converter in the traditional E-workshop. Based on the existing CAN/RS485/Ethernet protocol, a workshop communication system based on STM32F4 control chip is designed. The communication interface of CAN/RS485/Ethernet and the software implementation of protocol conversion are given. The simulation and experimental results show that the data transmission rate of the communication system is significantly better than the traditional point-to-point protocol converter, and the data transmission is accurate and the bit error rate is low. Therefore, the communication system is more in line with the development needs of manufacturing communications.
