Energy-saving and power-saving binary output flash flood sensing device

Abstract

The invention discloses an energy-saving and power-saving binary output type mountain torrent sensing device which comprises an independent water flow sensor and an independent water level sensor. The water flow sensor consists of a water flow impact sensing device and a tension measuring device, and the water level sensor comprises a water level follow-up device consisting of an outer floater, a crown block and inner and outer connection pull ropes. Short circuit plate electrodes are mounted in the water flow sensor and the water level sensor respectively and provided with electrodes with the minimum dimension delta or delta', measurement binary output range 2N and measurement length output range delta*2N, and all electrodes with equal weights are in short circuit connection. The short circuit plate electrodes in the water flow sensor include a high-order short circuit plate electrode and a low-order short circuit plate electrode. Numbers are outputted according to short circuit relation between short circuit plates and short circuit connecting lines of short circuit plate electrodes. Energy is saved by external arrangement of a rain starting switch device and a regular brief starting switch device. The energy-saving and power-saving binary output type mountain torrent sensing device which adopts binary output is simple and reliable in structure and easy to popularize.

Description

[0001] (1) Technical field [0002] The invention belongs to the category of geological disaster monitoring, and relates to a mountain torrent sensing device, in particular to an energy-saving and power-saving binary output mountain torrent sensing device. [0003] (two), background technology [0004] In the mountainous and hilly areas of our country, many natural disasters such as flash floods and mudslides occur every year, causing huge losses to people's lives and property. Prediction and forecasting of flash floods is particularly important. Sichuan University Journal, Volume 42, 2010, Supplement 1: 155-160, "Several Suggestions on Mountain Flood Prevention and Flood Prevention and Early Warning System Construction" written by Huang Hua et al., describes the main monitoring methods for mountain torrent prevention and control at present, from It can be seen from the article that in terms of monitoring means, there is no suitable flash flood sensor to warn and forecast the ...
