Abstract

The invention discloses a system for judging the moving direction of a human body, and the system judges whether the output voltage of an amplification circuit module is negative first and then positive or positive first and then negative through a micro central processing unit module, and further judges whether the human body enters a shop or goes out of the shop, a voice broadcast circuit module is controlled to carry out welcome broadcast or not carry out broadcast when going out or carry out other voice broadcast, so that the user experience is improved, and meanwhile, the labor of shop assistants is reduced.

Description

technical field [0001] The invention and the sensor field specifically relate to a system for judging the moving direction of a human body. Background technique [0002] There is an infrared detector at the entrance of many small shops nowadays, which is used to detect whether people come in or out. Come out, this will affect the user's experience. Contents of the invention [0003] The invention provides a system for judging the moving direction of the human body, which solves the problem of high cost of the existing sensor structure and the inability to adjust the angle, which is not conducive to sensing key areas, and the relative difference between the two feeding ports of the existing antenna design in the production process Problems that increase, are unstable, and cannot reduce the fault tolerance rate in production. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a system for judging the moving directio...
