Problems solved by technology

[0004] However, when there are disturbances such as vehicles passing by and nearby trees shaking in the external environment, the microwave monitoring method in the prior art may misjudge the above disturbances as the movement of the target object, resulting in inaccurate judgment results

Embodiment Construction

[0045] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

[0046] In the prior art, the microwave detection sensor converts the collected analog signal into a digital signal, and the MCU collects the digital signal, and then judges whether the value of the collected digital signal exceeds the preset value. It is determined that a moving object is detected. However, when there is interference such as vehicles passing by and nearby trees shaking in the externa...

Abstract

The present invention provides a method and device for monitoring the movement of an object. The method includes: acquiring N groups of feedback signals collected in N time periods, wherein each group of feedback signals includes M feedback signals, where N is an integer greater than or equal to 2, and M is an integer greater than or equal to 2; Perform preprocessing on each group of feedback signals in the N groups of feedback signals to obtain N preprocessing results; according to the sequence of time periods, calculate the difference between the preprocessing results corresponding to each two adjacent time periods to obtain N -1 difference; according to the absolute value of the N-1 difference, it is determined whether the object moves; the influence of environmental factors and sudden factors on the judgment result is reduced, and the accuracy of the judgment result is improved.

Description

technical field [0001] The present invention relates to communication technology, and in particular, to a method and device for monitoring object movement. Background technique [0002] Microwave refers to electromagnetic waves whose frequency is in the range of 300MHz to 300GHz and the wavelength is in the range of 1m to 1mm; the principle of microwave monitoring is: the microwave detector continuously emits microwave signals and receives the microwave signals reflected by objects; The frequency difference between the emitted microwave signal and the reflected microwave signal triggers the judgment of whether there is a moving object approaching, the size and moving speed of the moving object, etc.; microwave monitoring has been widely used in various fields, such as alarm probes and other security products and automatic Door sensors, etc.; improving the accuracy of the above trigger judgment is an urgent problem to be solved in the current microwave mobile monitoring proce...
