Research and Implementation of Collision Detection Based on Modbus Protocol

Abstract

In order to solve the communication errors resulted by traditional working condition multi-platform device communication using the custom protocol communication and link congestion malpractice brought by retransmission, it ensures network communication using time-sharing communication conflict detection based on mature Modbus protocol. Thereby it enhances the stability of the entire system during operation process, and provides simple, efficient, stable business specification interface for the future expansion of the system. After a comprehensive evaluation and analysis of system communication messages before and after improvement, system comprehensive evaluation target has improved. While the system is more flexible to modular design, develop transparent, structure open side and has a broad application prospects.
