Novel unmanned plant protection aerial vehicle liquid level detection device

Abstract

The invention discloses a novel unmanned plant protection aerial vehicle liquid level detection device and belongs to the technical field of agricultural plant protection. The detection device comprises an installation base, a gas inlet valve, a circuit case, a measuring tube and a mobile magnet ring, and the device is installed on a liquid storage tank of the unmanned plant protection aerial vehicle; the measuring tube and the mobile magnet ring are combined to achieve the function of slide rheostat; the gas inlet valve is installed on the installation base; the circuit case comprises a round shell body and a circuit board; powered by an external power supply, when the device works, the mobile magnet ring floats on the liquid level of the liquid storage tank and slides vertically along the measuring tube as the liquid level changes, and the circuit board conducts measurement on a resistance of the measuring tube which is converted into a voltage and a current signal through a circuit. The novel unmanned plant protection aerial vehicle liquid level detection device can provide accurate, intuitive and reliable data of the liquid level of the liquid storage tank for unmanned plant protection aerial vehicle work, improves efficiency of plant protection work, and facilitates monitoring of unmanned plant protection work.

Description

technical field [0001] The invention is a novel unmanned plant protection aircraft liquid level detection device. More specifically, it is a liquid medicine detection device used on a liquid storage tank of an unmanned plant protection aircraft. Background technique [0002] With the development of land intensification and the advancement of the rural land transfer system, large-scale cultivation has become the normal state of agricultural cultivation. The plant protection aircraft has an efficiency that cannot be achieved manually in chemical spraying. At present, most of the plant protection unmanned aerial vehicles cannot detect and display the liquid level of the liquid storage tank in real time during the spraying operation, and are often calculated based on experience or other parameters such as flow rate. It can be concluded that direct liquid level data cannot be obtained. Aiming at this problem, the present invention provides a simple and reliable liquid medicine d...
