Binary output landslide monitoring sensor

Abstract

The invention discloses a binary output landslide monitoring sensor. The binary output landslide monitoring sensor is composed of sensing rods, a pull rope and a displacement tension sensor. The displacement tension sensor is composed of a displacement tension sensing device and a displacement measuring device. A displacement tension connecting rod, a guide wheel and a sliding brush are arranged in the displacement tension sensing device. The displacement tension sensing device is mounted in the displacement measuring device. The displacement measuring device is provided with an insulated outer surface, short-circuit electrode plates and a stress spring. The short-circuit electrode plates are provided with electrodes, wherein the minimum size of the electrodes is delta, the measured binary output range of the electrodes is 2N, the electrodes with the same weight are connected through a short-circuit connecting line, the short-circuit electrodes corresponding to the short-circuit connecting line with the output weight smaller than N / 2 are distributed on the low-order short-circuit electrode plate, and the short-circuit electrodes corresponding to the short-circuit connecting line with the output weight larger than or equal to N / 2 are distributed on the high-order short-circuit electrode plate. A rain starting switch device and a regular transience starting switch device are arranged to save electricity. According to the binary output landslide monitoring sensor, binary output is adopted, output data are more accurate, and an accurate quantization basis is provided for geologic structure change.

Description

(1) Technical field [0001] The invention belongs to the category of geological disaster monitoring and relates to a landslide monitoring device. (two), background technology [0002] In our country, there are vast areas of mountains and hills, and roads are generally built along the mountains. This has just caused many natural disasters caused by landslides. The occurrence of geological disasters such as side slopes and tunnel collapses will cause huge property losses every year, and even endanger life safety. [0003] In order to solve geological disasters such as landslides and landslides, the state has invested a lot of manpower and material resources. The equipment and technical means for monitoring disasters have been continuously updated. However, due to the frequent occurrence of geological disasters such as mudslides and landslides in our country, the situation varies greatly from place to place, and the detection devices that can effectively provide solutions are...

However, due to the frequent occurrence of geological disasters such as mudslides and landslides in our country, the situation varies greatly from place to place, and the detection devices that can effectively provide solutions are not satisfactory

Chinese patent 201010195972.2 "Detection device based on omnidirectional tilt sensor and omnidirectional visual sensor" provides a debris flow and landslide detection device, which solves the problem of manual detection of debris flow and landslides in the past

This device has greatly improved the forecasting effect of geological disasters, but it still cannot fully meet the needs of forecasting and forecasting, especially in the digital output mode of resistance value, which needs to be improved to meet the needs of modern digital monitoring and management
