A kind of design and implementation about safety RTU

Abstract

This paper introduces the whole structure design of RTU, describes in detail the realization method of telemetry acquisition module, signal acquisition module, control module, encryption/ decryption module and communication module. Through the use of encryption and decryption chip, a communication mechanism based on SM2 encryption algorithm is designed, a design scheme of remote terminal unit with secure communication function is proposed, and the data security and reliable transmission problems of RTU in monitoring system are solved.
