摘要
现阶段在无线顶板压力监测系统中,无线压力传感器存在整机功耗高、电池更换频繁的缺点,且大多需要由本安电源供电的中继器安装在液压支架间进行数据中继,从而不能真正意义上解决有线方式中存在的传输线易被砸断、维护困难的问题。基于此,提出了一种基于SmartMesh IP无线传感网络的低功耗无线压力传感器设计方案。该方案中传感器由内置一次性锂电池供电,每个传感器都具有路由功能,无需专门的中继器进行中继传输数据且具有低功耗、数据传输可靠性高的特点。从而实现真正意义上的无线传输,解决了无线压力传感器的现存问题。
At the present stage of wireless roof pressure monitoring system, wireless pressure sensor presences shortcomings of high power and frequent battery replacement, and mostly need for data relay router which supplied by intrinsically safe power, installed between the hydraulic support. So it not really solves the problems of data transmission cable is easily be cut and equipment difficulty to maintenance which present in wired system. Based on this, we propose a design of low-power wireless pressure sensor based on SmartMesh IP wireless sensor networks. The sensor supplied by in-house disposable lithium battery, each sensor has routing function without dedicated repeater to relay data transmission and has low power consumption, high data reliability features. Therefore, we achieve real sense of wireless transmission and solve the existing problems of wireless pressure sensor.
