过去的井下漏电保护装置之间的通信都是采用现场总线通信，通信介质采用电缆，由于井下的特殊环境，通信很容易受到外界的干扰，造成漏电保护装置的拒动作或误动作，给煤矿造成安全隐患。为了解决这些问题，本文设计了一种应用于井下漏电监护系统的光纤通信系统，介绍了通信单元的实现，基于485总线通信。

In the past, the communication between underground leakage protection device are based on field bus communica-tion.But due to the special environment of the underground, communication is very susceptible to outside interference, which will result in leakage protection device refused action and malfunction, and pose a security risk to the coal mine.In order to solve these problems, this paper designs a kind of fiber communication system for underground leakage monitoring system and mainly intro-duces the communication unit of the leakage monitoring controller .It uses the superior performance of the 485 -bus communica-tion.
