一种基于水介质传输数据的新型山区河水流量监测装置

针对现有流量测量装置在山区使用中存在的缺陷和江西省山区地形复杂,河流多的特点,提出了一种适合山区河流流量监测的方法,利用音频信号在水介质中衰减小的特点,采用双音多频通信技术,通过水介质、大地和缆道钢丝循环索构建传输回路,设计了一种基于水介质传输数据的新型流量监测装置。水下数据采集装置利用水来触发电源开关,设计思路巧妙,功耗小,成本低,解决了当前山区使用面临的数据接收不到和难于实施五点法规范测量等实际问题,对山区落后的水情监测系统的升级换代起到了积极的推动作用。

THE NEW MONITORING DEVICE FOR TRANSFERRING THE FLOW OF RIVER IN MOUNTAIN AREAS BASED ON WATER MEDIUM

In order to solve the problem that defects of current flow measuring device in the mountain areas and complex topography, many rivers in Jiangxi province, we put forward a new method which is suitable for the application to mountain areas. We present a new monitoring device for transferring the flow of river in mountain areas by water medium. Based on the characters of audio signal in water is less attenuation, using Dual-Tone Multiple Frequencies （DTMF）, through the water, the land and cableway wire loop cable construct a transmission circuit. Device of data acquisition underwater uses water to trigger power switch. The designation makes the monitoring device low cost, portability, steady performance, and it solves some actual problems, such as the data receiving less in mountain areas and hard to carry out five point method. It has played an important role in the development of hydrological monitoring system in mountain areas.
