Design of environmental monitoring system of power distribution room based on modbus protocol

It is difficult to monitor indoor environment with wired monitoring for power distribution room in distribution automation system. For solving this problem, the wireless monitoring based on radio frequency technology is an effective method. An environmental monitoring system based on Modbus protocol is designed in this paper for power distribution room. The proposed system consists of wireless data transceiver module, wireless sensor module and concentrator modules. And working principle, hardware design and software design of each module was introduced. The practical application results shows that the real time wireless remote monitoring, for indoor environment in the power distribution room, is achieved by the designed environmental monitoring system, which has the good characteristics of fast response, high precision and reliability.
