Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings.

[0046] like Figure 1~3 As shown, an automated wireless monitoring and early warning device for debris flow is characterized in that it includes: a field monitoring device and an indoor monitoring device connected by wireless communication;

[0047] The field monitoring device includes a laser displacement sensor 2, a rain gauge 3 and a strain gauge 4 that are all connected to the wireless transmitting module 1, and the laser displacement sensor 2 includes a laser transmitter 5 and a laser receiver 6 that are arranged oppositely. The transmitting module 1, the rain gauge 3 and the laser receiver 6 are all arranged on the stable rock mass; the laser transmitter 5 is arranged on the landslide body 10; the strain gauge 4 is arranged in the area where debris flow easily flows through;

[0048] The indoor monitoring device includes an antenna installed at a high place in a b...

Abstract

The invention discloses an automatic debris flow wireless monitoring prevention and early warning device. The automatic debris flow wireless monitoring prevention and early warning device is characterized by comprising a field monitoring device and an indoor monitoring device, wherein the field monitoring device and the indoor monitoring device are in wireless communication connection. The field monitoring device comprises a laser displacement sensor (2), a rain gauge (3) and a strain gauge (4), wherein the laser displacement sensor (2), the rain gauge (3) and the strain gauge (4) are connected with a wireless transmission module (1). The laser displacement sensor (2) comprises a laser transmitter (5) and a laser receiver (6), wherein the laser transmitter (5) and the laser receiver (6) are arranged in an opposite mode. The wireless transmission module (1), the rain gauge (3) and the laser receiver (6) are arranged on a stable rock mass, the laser transmitter (5) is arranged on a sliding mass (10), and the strain gauge (4) is arranged in a region which debris flow easily flows through. According to the automatic debris flow wireless monitoring prevention and early warning device, field monitoring and indoor monitoring are combined, multiple prevention and early warning measures are taken, the prevention and early warning effect is remarkable, and the requirement for early warning of debris flow in a remote mountain area can be met.

Description

technical field [0001] The invention relates to an automated wireless monitoring, prevention and early warning device for debris flow, in particular to an automatic, low-cost and systematic wireless monitoring, prevention and early warning device for debris flow, belonging to the technical field of wireless monitoring, prevention and early warning. Background technique [0002] Landslides and debris flows are geological disasters or engineering geological disasters that often occur in mountainous areas, on both sides of roads, on both sides of river valleys, and road construction sites. They erupt suddenly, cause great damage, and are difficult to control and predict. If the prediction is not timely, it will cause huge casualties and material damage. loss. Due to the complicated conditions for the formation of debris flow such as topography and geology in my country, at present, the forecast of debris flow can only be done regionally and on a large scale, and it is not possi...
