矿用无线甲烷传感器的设计要求

摘要

分析了目前对矿用甲烷传感器在显示值稳定性、响应时间、误差范围等方面的性能要求,指出矿用无线甲烷传感器除了要符合矿用甲烷传感器的性能要求外,其供电电池及通信信号也要符合设计要求,即应采用定时唤醒接收方式、降低占空比、提高无线收发速率来降低功耗,并设计成小型化本质安全设备;介绍了矿用无线甲烷传感器设计中常见的问题及对策;最后从感知矿山物联网适应性、无线通信、后备电源、天线、遥控功能等方面提出了确保矿用无线甲烷传感器甲烷检测性能及安全性能的设计要求.%The paper analyzed performance requirements of mine-used methane sensor about stability of rndisplayed value, response time and error limit at present, pointed out battery and communication signal of rnmine-used wireless methane sensor should accord with certain design requirements besides performance rnrequirements of mine-used methane sensor, namely, timed wakening and receiving way should be used,rnduty cycle should be decreased and wireless transceiving rate should be improved to decrease power rnconsumption, and mine-used wireless methane sensor should be designed as small-sized intrinsically safe rndevice. It introduced common problems in designing mine-used wireless methane sensor and corresponding rncountermeasures. Finally, it put forward design requirements to insure measuring performance and safety rnperformance of mine-used wireless methane sensor in terms of adaption of Internet of things of sensor rnmine, wireless communication, backup power supply, antenna, remote control function and so on.
