In virtue of the interference of strong electric magnetic field to communication caused by the electric explosion wire automatic spraying device during the electric explosion, this paper designs an automatic wire-feeding system based on Modbus communication protocol to improve the reliability and stability of the system. The following schemes are proposed: In the automatic wire-feeding system, RS485 and RS485 to RS232 interface are used to improve the anti-interference ability of the data in the strong electric magnetic field by shielded twisted-pair connection and Modbus RTU transmission mode. The automatic wire-feeding system is composed of the master equipment with STM32F746 main control chip as the core and several slave equipment with C8051F020 single chip microcomputer as the core. Modbus communication protocol is utilized to actualize the communication between master and slave equipment. The stable transmission of long distance data between master and slave equipment of the automatic wire-feeding system is proved by experiments to ensure the effective operation of the experimental device.
