A water level monitoring device

Abstract

The invention provides a water-level monitoring device which comprises a floating body module, a water level early-warning module, an information acquisition module and a processor module. The floating body module comprises a first magnet and is used for floating on a water surface to float up and down according to the water level. The water level early-warning module comprises a plurality of ironsheets which are in series connection and a second magnet, and the second magnet is constructed to have weak attractiveness effect on the multiple iron sheets in series connection to enable the ironsheets and the information acquisition module to be disconnected. The first magnet of the floating body module is constructed to approach the iron sheets along with rising of the water level so as tohave a strong attractiveness effect on the iron sheets, and therefore different iron sheets in the multiple iron sheets in series connection are connected with the information acquisition module. Theprocessor module is constructed to be electrical signals from the information acquisition module to generate water level monitoring signals. The water-level monitoring device has the beneficial effects of being intelligent, low in cost, convenient to mount, and good in flexibility.

Description

technical field [0001] The invention relates to the technical field of electronic measurement applications, in particular to a water level monitoring device. Background technique [0002] Building tunnels can reduce the traveling distance of vehicles and the cost of road construction, and shorten the distance of roads and railways. Reduce travel time, thereby increasing passenger capacity and developing the transportation network. In addition, tunnels also have many functions, such as tunnels for urban underground drainage or water supply, tunnels for laying gas pipelines or large-scale power transmission lines, subway tunnels, water diversion tunnels for agricultural irrigation, and water tunnels for agricultural irrigation. Special tunnels for national defense and military, etc. However, tunnel accidents are also increasing year by year. Due to the special geographical location of the tunnel, it is difficult to know the situation inside the tunnel from the outside. situ...

Problems solved by technology

[0003] At present, the Internet of Things technology is developing rapidly. The Internet of Things can realize intelligent monitoring between things, which greatly facilitates various industries in society. Therefore, monitoring devices based on the Internet of Things have become a development trend, but the use of electronic devices to measure Water level situation and realization of transmission display have not been reported at home and abroad
