Problems solved by technology

Single-point water leakage detectors can be divided into liquid level meter method, photoelectric method, etc., which place the probe in the place where liquid leakage may occur, and send a signal when there is water; its disadvantage is that it has requirements for the installation location, and existing equipment Sufficient water is required

The microwave method uses the sensitivity of microwaves to the dielectric constant of the medium to detect. Because the moisture content of each material is different, the dielectric constant is different. Therefore, the location of the leak can be detected by microwaves, which is also called the microwave moisture measurement method; its disadvantages The coverage area is small, and it is basically ineffective for the material of the steel structure

Water leakage detection line is divided into two types: non-positioning and positioning. Generally, it is a multi-core line. When water flows through the detection line, the resistance value of the detection line will be changed, and the controller can detect the change of the signal; the disadvantage is the cost of the detection line. High, especially the positioning detection line, which is mainly foreign products, can reach 100 yuan per meter, which is difficult to apply to water leakage detection in small places

In addition, although various existing mature technologies are suitable for industrial-grade applications, they generally have extremely high hardware requirements, occupy a large space, consume high energy consumption, high costs, and difficult maintenance. They cannot be directly applied to automobiles at all, so they need to be reconsidered. A New Type of Liquid Leakage Detection Device
