All-weather water flow monitoring and early warning system based on Internet of Things

Abstract

The invention discloses an all-weather water flow monitoring and warning system based on the Internet of things. Electricity is generated using a solar panel and a water power generation device so as to provide energy for the whole device. The water power generation device is equipped with an infrared transmitter and an infrared receiver inside. The water speed is judged by the speed of the wheel propeller. A foundation pillar is equipped with multiple water sensors to judge the water level, and is equipped with a temperature sensor and an air pressure sensor to judge the meteorological condition. The device is internally equipped with a GSM antenna, a GSM communication circuit, an SIM card, a MCU processor, an A / D converter and a memory to send data and warning information to the staff. The geographic information of multiple water flow monitoring devices and captured water flow condition data constitute an Internet-of-things system. All-weather monitoring and warning are carried out on a monitored water area.

Description

technical field [0001] The invention relates to the field of natural disaster monitoring devices, in particular to an all-weather water flow monitoring and early warning system based on the Internet of Things. Background technique [0002] Floods are rivers, oceans, lakes and other water bodies that rise above a certain water level, threatening the safety of relevant areas, and even causing disasters. A natural phenomenon of rapid rise. Compared with historical data, the frequency and severity of floods are fairly consistent with population growth trends. It has to be admitted that my country's rapid population growth, expansion of arable land, reclamation of lakes, deforestation and other man-made damages are constantly changing the state of the surface, changing the confluence conditions, and aggravating the degree of floods. Flood disaster is a natural disaster with high frequency, wide range of damage and the most serious impact on the national economy in my country. ...

Problems solved by technology

[0005] Existing water flow monitoring devices are mainly divided into two categories. Traditional ones rely on checking water level scales to monitor water level changes, and some add cameras to transmit image information to staff. The disadvantage is that it consumes manpower and requires manual viewing of monitoring images around the clock, which is less efficient. Low and low reliability; Another method uses satellite remote sensing technology to monitor large rivers. The disadvantage is that the small fluctuations of the river are difficult to be captured by satellites, which costs a lot of money and has low accuracy.
