Abstract

The invention provides a distance measurement method and device, a pesticide box, operation equipment, electronic equipment and a medium, and relates to the technical field of measurement and control. The method comprises the steps that a first digital echo signal is received, the first digital echo signal is obtained by processing an original echo signal, and the original echo signal is an echo signal of a measurement signal sent by a signal receiving and sending module to a measured target; analyzing the first digital echo signal to obtain frequency spectrum information of a plurality of frequency points corresponding to the first digital echo signal; according to frequency spectrum information of a plurality of frequency points corresponding to the first digital echo signal and frequency spectrum information of a plurality of frequency points of at least one second digital echo signal before the first digital echo signal, echo cancellation processing is carried out, and a target frequency point is obtained; and according to the frequency of the target frequency point of the first digital echo signal, determining the distance of the measured target relative to the signal transceiving module. By applying the embodiment of the invention, the accuracy of the distance information of the measured target relative to the signal receiving and transmitting module can be improved.

Description

technical field [0001] The present application relates to the technical field of measurement and control, in particular, to a distance measurement method, device, medicine box, operating equipment, electronic equipment and media. Background technique [0002] The radar level gauge is a non-contact distance measuring device, which can measure the distance of the measured target (such as liquid, granular object) through electromagnetic waves, and is not affected by environmental factors such as temperature and air pressure. The measurement principle of the radar level gauge is to send a microwave signal to the measured target through the signal transmitting module, and then process the reflected echo signal to obtain the distance between the measured target and the signal transmitting module. [0003] However, the microwave signal emitted by the radar level gauge inevitably propagates along one direction, which will cause signals generated by other objects other than the measu...
