Abstract:
In the process of data transmission of electricity meters, due to the influence
of the characteristics of the transmission channel medium and the interference of the
external environment, data transmission errors are caused. This paper introduces the
principles of several common communication error control coding methods and gives
the corresponding implementation methods.
在电能表数据传输过程中,由于受传输信道介质自身特性和外界环境
干扰的影响,导致数据传输错误,为提高通信的可靠性,常采用差错编码方式
纠错。介绍几种常用的通信差错控制编码方式的原理,并给出相应的实现方法。
