Abstract

The embodiment of the invention discloses a liquid level monitoring device and a vehicle oil level monitoring system. The liquid level monitoring device is used for measuring the liquid level of liquid in a liquid storage device. The liquid level monitoring device includes a liquid level monitoring module and a control module; the liquid level monitoring module is arranged in the liquid storage device and electrically connected with the control module, and comprises a shell, a floater arranged in the shell and a liquid level sensing block arranged on the floater, a liquid inlet is formed in the bottom of the shell and used for balancing the liquid level in the shell and the liquid level in the liquid storage device, the floater is used for floating on the liquid surface, and the liquid level sensing block is electrically connected with the control module and used for detecting liquid level information and providing the liquid level information for the control module; the control moduleis arranged outside the liquid storage device and used for receiving the liquid level information. The liquid level monitoring device can accurately monitor the liquid level of the liquid in the liquid storage device.

Description

technical field [0001] The embodiments of the present invention relate to liquid level detection technology, in particular to a liquid level monitoring device and a vehicle oil level monitoring system. Background technique [0002] Existing liquid level detection technologies include ultrasonic, liquid pressure and gas pressure measurement methods. The ultrasonic measurement method is mainly to calculate the distance according to the return time when encountering the medium through the sound wave transmission. The liquid pressure measurement method is to measure the liquid level depth by means of the pressure principle. The gas pressure measurement method is to use the principle that the gas can be compressed by the liquid to test the air pressure. Calculate the liquid level height. [0003] Ultrasonic liquid level measuring devices are bulky and have requirements for measuring distance accuracy. Generally, it is difficult to measure distances within 20cm, so they are suita...
