The application of RS-485 communication interface in KJ93 monitor and control system of mining safety and production

Abstract：The KJ93 system of mining safety and production is a distributed computer monitor and control system. According to the characteristic of the distributed system and engineering requirements, the RS?485 communication interface standard is applied to this system. It also has the features of hardware opening, strong anti_disturbance, ESD protection and building computer network easily. The application of RS?485 communication interface in KJ93 monitor and control system of mining safety and production is discussed.
