Problems solved by technology

However, the weather forecast can only obtain one of the two necessary conditions for the formation of debris flow, that is, the water source condition.
And another necessary condition, i.e. the provenance condition (source of solid matter), is more complicated, and it will take some time before it is practical.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] Such as figure 1 In the structural block diagram shown, on-site monitoring equipment (1), transmission network (2), monitoring center server (3), and monitoring center client (4).

[0014] The on-site monitoring equipment (1) is composed of a telemetry intelligent rain gauge (11), a debris flow infrasound alarm (12), an ultrasonic mud level gauge (13) and an image monitoring equipment (14). Responsible for the collection and processing of on-site rainfall, debris flow infrasound, mud level, images and other information. The telemetry smart rain gauge (11) is placed in a certain place in the mudslide basin (the place is an indicator place where the mudslide flow is formed in the basin), and the rain gauge can record, store and send the hourly (in minutes) rainfall in real time to early warning system. The structural block diagram of telemetry intelligent rain g...

Abstract

The invention discloses a mud-rock flow early alarm system. The system consists of field monitoring equipment (1), a transmission network (2), a monitoring centre server (3) and a monitoring centre client (4), wherein the field monitoring equipment (1) consists of an intelligent remote measuring rain gauge (11), a mud-rock flow infrasound alarm (12), an ultrasonic mud level meter (13) and image monitoring equipment (14); the monitoring centre server (3) consists of a rainfall information receiving and processing system (31), an infrasound information receiving and processing system (32), a mud level information receiving and processing system (33) and an image receiving and processing system (34); and the monitoring centre client (4) consists of an information display unit (41), a data analysis unit (42) and a threshold configuring unit (43). The mud-rock flow early alarm system integrates rainfall monitoring, mud level monitoring, mud-rock flow infrasound monitoring and image monitoring together, and expresses according to the integration of the information, of rainfall, mud level, infrasound and image, which shows that the mud-rock flow is coming or comes to achieve the effect of signal compensation and comprehensive judgment.

Description

Technical field [0001] The invention belongs to the early warning system for monitoring mud-rock flow, especially in the field of manufacturing mud-rock flow early warning devices whose lead time is not as good as the forecast but far greater than the alarm. Background technique [0002] At present, the forecast part of the research on debris flow early warning system at home and abroad relies too much on weather forecast. However, the weather forecast can only obtain one of the two necessary conditions for the formation of debris flow, that is, the water source condition. And another necessary condition, i.e. provenance condition (source of solid matter), is more complicated, and it will be a long time before it is practical. As for the current various alarm methods (such as ground sound method, mud level method, disconnection method, impact force method, etc.), they all have their limitations, so people are willing to integrate them together to complement each other (or m...
