摘要: 在分析RS232和RS485串行通信接口工作原理和特点的基础上,确定了矿用馈电开关远程数据通信采用RS485标准接口的串行通信方案,实现了馈电开关和上位PC机的双向通信功能。实验表明该串行通信方法通信距离长,传输数据准确可靠,具有一定的实用价值。Abstract: On the basis of analysis of the working principle and characteristics of RS232 and RS485, serial communication method was confirmed that the long distance data communication of mine-used feeder switch can be realized by adopting RS485 serial communication standard interface. The switch can communicate with upper PC. The experiments showed that the method is long distance in communication and reliable in data transmission and has practical value.
