The Design And Implementation Of RSSP-? Safety Communication Interface

With the rapid development of the railway industry,high-speed railway has become one of the indispensable means of transport.Since the running speed of the high-speed railway has reached nearly 500km/h,it is not realistic simply relying on the driver's driving.The safety of the train running depends on a series of communication signal equipment.Communication signal equipment is usually realized through the security system,adopting many error proofing measures to improve the reliability and security of the system.One of the most common measures is hardware redundancy.In addition,the information security of the communication signal equipment is particularly important;the RSSP-? security communication protocol is to guarantee the safety of the ground equipment through the use of train control system.The main content of this paper is to construct the secure communication interface based on the three module redundancy simulation system.In other words,both the simulation of RSSP-? protocol and observation for the communication process and the failure of RSSP-? protocol are to be realized through the integration of redundant technology and the RSSP-? security communication protocol,which is of great significance for the study of safety system and safety communication.In order to achieve secure communication interface,this paper firstly analyzes the safety communication protocol and the redundancy technology.Then the paper introduces the working principle of the protocol and key technology,the protocol's security protection process,and the related algorithms used in the protocol.Furthermore,with the use of thriple modular redundancy technology,the architecture of the safety communication interface and the function of each module are designed on the basis of RSSP-? safety communication protocol.Finally,the safety communication interface is realized with VC++6.0 as its development platform.The experiment results show that the safety communication interface introduced in this paper realizes the RSSP-? secure communication protocol,and can operate normally in the case of the failure of redundant system.
