基于RS-485的串行通信在电梯呼梯系统中的应用

The application based on serial communication of RS-485 in calling elevator system

主要阐述了RS-485作为串行呼梯中数据传输的标准接口如何可靠地在电梯呼梯系统中的应用,以及呼梯信号在通信线缆中传输的可靠技术。应用该通信方式和技术的产品已经大量应用到了生产实践中。从目前来看,该产品可靠性高,具有很好的经济效益与推广价值。

This text mainly explains that RS - 485 is used in serially calling elevator system as standard interface of data transmission, and the reliable technology that the signal of calling elevator is transmitted in the communication cable. The productions that used this communicate way and technology already largely apply to production practices, qhis product has high reliability, and has very good economic benefits and value to popularize at the present time.
