摘要
针对大面域屋面,研发了一种具有雨量触发机制的无线水位监测系统。首先基于超声波测距原理开发了水位设备,组建了无线通信网络,并搭建了水位监测系统云平台;然后分析了水位设备测量精度的主要影响因素,通过水位设备测量标定试验,验证了水位设备的稳定性;最后将无线水位监测系统应用于北京大兴国际机场航站楼屋面。提出的无线水位监测系统具有稳定性强、自动化高和无线监测的特点,提供了一种面向大面域屋面的水位监测手段。
A wireless water level monitoring system with a rainfall trigger mechanism was developed for large surface area roof.Firstly,based on ultrasonic distance measurement principle,a water level device was developed to establish a wireless communication network and set up a cloud platform for the water level monitoring system;then,the main factors affecting the measurement accuracy of the water level device were analyzed to verify the stability of the water level device through calibration tests and finally,the wireless water level monitoring system was applied to the roof of the terminal building of Beijing Daxing International Airport.The proposed wireless water level monitoring system features high stability,high automation and wireless monitoring and provides a means of water level monitoring for large surface area roof.
