The Design And Implementation Of Ethernet Safety Communication Module

As the high-speed railway is developed rapidly and the highest speed for railwaypassenger traffic can even reach481km/h, it is obviously impossible to steer one trainbarely by a driver, but by a system for safety purpose. Considering that there are manyindividual safety platforms according to different safety systems, to save resource anddevelop systems effectively and efficiently it is necessary to provide a universal andcompatible safety platform for varied safety systems. Since this universal safetyplatform will need to communicate with various equipments, it is a demand that theremust be an Ethernet Safety Communication Module to communicate with EthernetSafety Equipments.After analyzing the Ethernet Safety Communication Module in different aspects,ranging from system structure, safety protocol compatibility, communication way, tothe security of operating system,2oo2system structure is adopted and RSSP-â…  safetyprotocol, RSSP-â…¡ safety protocol and TCP-IP protocol is designed under no operationsystem condition. With a voting mechanism to insure the correctness of data thathaving been processed, it is fulfill the requirements of communication safety throughEthernet Safety Communication Module and universality for various safety systems.
