High-frequency isolation measurement digital water level gauge for car water tank

Abstract

The invention provides a high-frequency isolation measurement digital water level gauge for a car water tank, and relates to water level detection of the car water tank. The digital water level gaugeis provided with a water level sensor, a water level converter, a water level display and a power supply. The water level sensor is arranged at the outer bottom of the car water tank. The output end of the water level sensor is connected with the input end of the water level converter. The output end of the water level converter is connected with the water level display. The water level display islocated in a cab. The power supply is connected with the water level sensor, the water level converter and the water level display. The water level sensor is used to generate a high frequency measurement signal. The water level converter is used to receive a single bus level signal of the water level sensor. The water level display is use to receive data transmitted from the water level converter. The digital water level gauge is convenient for a driver to use, so that the driver can concentrate on driving without worrying about the water level of the water tank. The safety of driving is effectively improved. The digital water level gauge has the advantages of simple installation, safe use, saved water saving cost, convenient use and accurate measurement.

Description

technical field [0001] The invention relates to the detection of the water level of an automobile water tank, in particular to a digital water level gauge in a high-frequency isolation measurement mode for the automobile water tank. Background technique [0002] Large trucks need to brake frequently or for a long time when driving on hilly areas or slopes, which will cause the temperature of the brake drum (disc) and brake shoe to rise sharply, and the temperature of the wheel hub will increase. High enough to make the tire pressure too high to cause a blowout phenomenon and cause a safety accident. Studies have shown that the brake temperature is often above 300°C, and can reach 600-700°C in an instant. When the temperature of the friction lining in the brake rises, the friction coefficient will decrease significantly, resulting in a significant decrease in the braking torque, which will cause the thermal decline of the braking efficiency, that is, the constant decrease of...

AI Technical Summary

Problems solved by technology

[0008] All of the above methods must be stopped for inspection, and it is impossible to grasp the water volume (or water level) in the water tank in real time during driving, and if it is a pneumatic water tank (because the water tank is completely airtight to ensure airtightness), it is impossible to accurately judge the water volume. How much (water level) is there, which brings great inconvenience to the driving of the majority of drivers and friends
