Problems solved by technology

[0003] The current monitoring method mainly relies on the upstream rainfall monitoring station. Using the comprehensive rainfall data reported by the upstream rainfall monitoring station to estimate the intensity of mountain torrents requires a lot of work and a lot of investment
In addition, sending people along the railway line to conduct actual inspections on bridges and tunnels, the workload is heavy and very difficult

Embodiment

[0014] A1, A2, A3, A4 buoy position sensors are hung on the launching side of the pier at a certain distance. The water wave line indicates the current water level, the buoy position sensors A1 and A2 are already in the floating position, A3 is floating, and A4 is still in the hanging position because the water level is not enough. A1, A2, A3, and A4 are all placed in a basically airtight box, on the one hand to avoid damage to the buoy position sensor by water flow and sundries; on the other hand, there is an opening on one side of the box and an inward-opening valve, the opening can detect or Replace the buoy position sensor, and because the valve opens inward, it is easy for water to enter the box, and the water will be discharged slowly, so as to avoid the water level rising and falling too frequently due to the waves of the water, which will cause the radio module of the buoy position sensor to work too frequently, and the battery will be drained. Lots of electricity. It...

Abstract

The invention provides a flash flood water level monitoring and pre-warning system, a monitor sensor of which is a buoy position sensor. The buoy position sensor is a digitally coded wireless electric module, wherein a conductive suspended hammer or a conductive rod, a conductive ring and a conductive contact are arranged in the buoy; generally, the conductive suspended hammer or conductive rod is not contacted with the conductive ring, and the sensor does not consume electricity; and when the buoy is inclined to a certain angle due to water level rising, the conductive suspended hammer or the conductive rod is contacted with the conductive ring, the wireless electric module is electrified to work, a coded wireless electrical signal is sent out and received by a monitoring center and a warning station of a protected region through a relay station, and an alarm is sent out. When the weight completely floats in the buoy position sensor, the conductive ring is separated from the conductive contact, the circuit is disconnected, and the sensor does not consume electricity, so the system can work repeatedly. The water level monitoring and pre-warning system can warn the absolute height of water level, and warn the instant strength of flood.

Description

Technical field: [0001] The invention relates to an early warning system for monitoring the water level of mountain torrents. It can effectively monitor the real-time absolute height of the water level. It can also monitor the real-time intensity of flash floods. In particular, monitoring the immediate intensity of flash floods is important because it is the intensity of flash floods that is most damaging. Obviously, for a bridge, for example, if the water level rises by 1 meter within an hour during a flash flood, and if the water level rises by 1 meter within 10 minutes, there must be a big difference in the impact and damage to the bridge. The same is true for downstream residential areas. Knowing the actual intensity of flash floods can provide accurate warnings and effectively protect the lives and properties of downstream residents. [0002] The invention can effectively monitor the real-time absolute height of the water level, and can effectively monitor the outbreak ...
