Description

Technical Field

[0001] The utility model relates to water depth monitoring, in particular to water depth monitoring based on a pressure sensor. Background Art

[0002] The water gauge is an ancient and classic measuring tool with a wide range of applications. It is not only used for agricultural irrigation and river water level detection, but also plays an important role in construction, navigation, geographic surveying and other fields. Nowadays, the water gauge is still a commonly used measuring tool in water conservancy projects. In the hydrological monitoring of rivers, lakes or reservoirs, the water gauge can provide simple and intuitive water level measurement data. At present, the liquid level value is mainly read by human eye observation, which will result in inaccurate readings, and the requirements for real-time observation are high for operators, which will increase the work cost and workload of the staff.

[0003] Existing patent document CN 208653583 discloses a marine digital water gauge, which includes a digital display handle, a ruler, a ruler retracting and releasing device and a ruler weight. A signal processing device is provided inside the digital display handle and the signal processing device is connected to a pressure sensor on the ruler weight. After the pressure sensor generates an electrical signal, the electrical signal is transmitted to a signal receiving unit to obtain liquid level data, and the display screen displays the liquid level data. This method improves the accuracy of the water gauge reading, but the energy required increases and the implementation cost increases; Existing patent CN 116718251 discloses a video visualization water gauge, which includes a water gauge, a pressure sensor and a monitoring camera, etc., and uses the buoyancy of the water body and a marking plate to perform visual reading of the water gauge. This method reduces the technical problem of high labor intensity caused by operators going to various sites, but manual reading will increase the reading error; Existing patent CN 106768164 discloses an electronic water gauge, which includes a motor, an air pump, a pressure sensor, and a controller. By conveying gas to the cavity in the water gauge and then using the principle of a communicating vessel, the water level value is calculated. This method solves the problem that the electronic water gauge is easily affected by water quality, but the implementation cost increases; the existing patent CN 102910254 discloses a portable water gauge marking device, which includes a pressure sensor, a wireless data transmission module, an embedded device and a display module. This method can intelligently obtain a marking device for the ship's waterline, and has the characteristics of being light and easy to carry, and having strong mobility. However, this method requires manual placement of the water gauge, and the operation is complicated; the existing patent CN 207487767 discloses a contact electronic water gauge based on a thin film pressure position sensor, which includes a thin film potentiometer, an AD conversion circuit, a processor, a power supply and a communication circuit. This method can be very conveniently applied to various environments, but the implementation cost increases.

[0004] It can be seen that the prior art still lacks a complete and mature invention device for the problem of water depth monitoring. Utility Model Content
