A liquid volume monitoring device and monitoring method

Abstract

The invention relates to the technical field of monitoring, in particular to a liquid volume monitoring device and monitoring method. The liquid volume monitoring device comprises an external corrector, and a liquid volume monitor is in communication connection with the external corrector; the liquid volume monitor comprises a first cover body and a second cover body which cover each other, a circuit board is arranged between the first cover body and the second cover body, the circuit board and the second cover body bond closely to form a closed air chamber, and an air vent is formed in the first cover body; a first detecting device and a second detecting device are arranged on the circuit board, and a third detecting device used for detecting the liquid volume flows out of a medical kit is arranged on the external corrector; a processor used for processing detection numerical values of the liquid volume monitoring device is arranged on the circuit board. According to the liquid volume monitoring device, through the intensity of pressure of the closed air chamber detected by the first detecting device and the ambient atmosphere detected by the second detecting device, liquid level information of the medical kit can be obtained through the difference value between the intensity of pressure of the closed air chamber and the ambient atmosphere.

Description

technical field [0001] The invention relates to the technical field of monitoring, and more specifically relates to a liquid volume monitoring device and a monitoring method. Background technique [0002] The agricultural plant protection UAV combines unmanned helicopter technology and pesticide application technology. It has the advantages of small size, no need for a special airport, flexible control, can take off and land in the field, and the downwash airflow can improve the effect of target drug application. , Pest control in small fields or local precision application of pesticides in large fields are attracting more and more attention from all walks of life. [0003] The medicine box is a key component of the plant protection UAV. During the plant protection operation, the medicine box is in a state of variable quality, and the amount of medicine in it gradually decreases as the operation progresses, which is a process of dynamic change. Therefore, in order to carry ...

Problems solved by technology

However, there are still some differences between the liquid level and the liquid volume. The liquid level cannot directly represent the liquid volume information. In addition, the single-pressure liquid level monitoring device needs to be calibrated repeatedly when the atmospheric pressure of the external environment changes.
