Problems solved by technology
Traditional water monitoring methods consume a lot of manpower, material resources and financial resources, but there is still no simple and feasible way to collect rainfall during the flood season, and the collected data is not accurate enough
In order to realize the real-time monitoring of the water level in the reservoir area, in recent years, automatic water level measuring devices such as magnetic floating beads, pressure, and ultrasonic have been successively introduced at home and abroad. Due to the strict requirements of rain sensor price and energy, it is still blank so far

Embodiment Construction
[0088] Below in conjunction with accompanying drawing and embodiment, the present invention is further described:
[0089] 1. For the flood monitoring system of ordinary medium and large reservoirs, according to figure 1 , figure 2 implement.
[0090] 1. Sub-area node group 1
[0091] There are many nodes distributed in each sub-area, and wireless communication between nodes. Nodes include two types: rain sensor node 1A and sink node 1B, where rain sensor node 1A is used to collect rainfall data in the sub-area (see ZL 200610019165.9); sink node 1B is a rain sensor without the rain sensor and signal conditioning circuit The node is used to process the rainfall and water level data transmitted from the rain sensor node 1A and the adjacent electronic water level scale 2 in the sub-region, and transmit the processed data to the sink node 1B which is closer to it in the next sub-region water regime data.
[0092] The sensor nodes in the n sub-regions usually remain in a dorm...

The system for monitoring flood of reservoir includes node cluster in sub area, electronic water gauge, RS232 interface circuit, terminal data processor (TDP), sensing node, and terminal concourse node (TCN). Rainfall sensing nodes and electronic water gauges in the node cluster in sub area transmits collected rainfall data and water level data to concourse node in the place located respectively.Then, the data are fed back to TCN in data center of flood terminals according to flooding mode or mechanism of geographical energy active route (GEAR) along direction of data transmission grads. Flood of reservoir is obtained in real time after processing by TDP. The invention can collect rainfall amount of reservoir area in real time, water level, and information of runoff. Advantages are: reliable communication, good real time performance, accurate measure, minor power waste, and low cost.
Description
technical field [0001] The invention relates to a reservoir flood situation monitoring system, in particular to a reservoir flood situation real-time monitoring system and method based on a wireless sensor network. Background technique [0002] For a long time, the contradiction between flood control and prosperity of reservoirs in our country has been very acute. For example, when there is heavy rain in the early part of the flood season, the reservoir is afraid to store water for the sake of safety, and there is often no water to store in the later period. Therefore, the safe use of flood resources and optimal regulation have become one of the topics of great concern to water conservancy workers. Its main contents include: [0003] 1. Realize the analysis of weather trends according to the facing time period; [0004] 2. Real-time monitoring of water regime changes and flood season rainfall in the reservoir basin; [0005] 3. According to the rainfall in the flood seaso...
