摘要/Abstract

摘要： 为提高配电房的环境监控力度和运维管理水平，设计了一款能实时监测多种气体浓度和温湿度的多功能传感器。对传感器的原理、电路设计、软件设计和功能参数等进行了详细介绍。传感器以STM32L151RDT6微处理器为主控芯片，以先进光谱和电化学技术为原理对多种气体同时进行检测，使用基于ZigBee（一种短距离无线传输协议）的无线传输模块和485有线网络实现传感器与监控中心之间的数据传输和通信，通过上位机对配电房运行状态作出判断和预警。经过测试：设计的KIS-GTH5A型多功能传感器的气体检测精度在量程的±3%之内，温度和相对湿度检测精度分别在±0.5 ℃和±3%之内。具有性能高、体积小、功耗低等优点，符合配电房气体的浓度和温湿度的检测要求。

Abstract: A multifunctional sensor which can monitor a variety of gases, temperature and humidity in real time is designed to improve the environmental monitoring and operation management level of the distribution room. A detail introduction is made to the sensor’s schematic, hardware circuit design, software design and functional parameters. The sensor uses the STM32L151RDT6 microprocessor as the main control chip, and the advanced spectrum and electrochemical technology as the principle to detect a variety of gases at the same time. Based on ZigBee's wireless transmission module and 485 wired network, the data transmission and communication between the sensor and the monitoring center are realized. The operation state of the distribution room can be judged and forewarned through the upper computer. Performance testing results show that the designed KIS-GTH5A multi-functional sensor has a detection accuracy of ±3%FS for gas, ±0.5 ℃for temperature and±3%RH for humidity. Therefore the designed sensor has the advantages of high performance, small volume and low power consumption, and meets the requirements for gas, temperature and humidity detector in distribution room.

Key words: multifunctional sensor, real-time monitoring, spectrum measurement, single chip microcomputer, wireless transmission
