Social contact alarm system based on laser ranging

Abstract

The invention discloses a social contact alarm system based on laser ranging. The system comprises a laser ranging module, a central control module and a warning module, wherein the central control module is connected with the laser ranging module and the warning module; the laser ranging module is used for detecting the spacing distance of target human bodies through laser; the central control module is used for driving the warning module to send out an alarm signal when the spacing distance is smaller than a preset safety distance. The system can detect the spacing distance of the target human bodies through the laser, and automatically sends out the alarm signal when the spacing distance is smaller than the preset safety distance to prompt the target human bodies to keep the safety distance, so that people are prevented from getting close to each other, and virus propagation is avoided. The system can be widely applied to windows of banks, hospitals, governments and the like where face-to-face business handling is needed, automatically remind customers and workers to keep an enough safe distance, and can effectively reduce the risk that the customers and the workers suffer from virus infection in the business handling process in the virus prevalence period.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a social alarm system based on laser ranging. Background technique [0002] People need to keep a safe distance of more than 1 to 2 meters when handling business at the counter. In response to this safety requirement, a reminder is given when the separation distance is smaller than the safety distance, so that the separation distance can be adjusted in time to reduce the risk of mutual infection of diseases. [0003] Prior art all is to remind customers to keep a safe distance by broadcasting voice in the lobby. But relying on voice prompts alone has a limited effect. Contents of the invention [0004] The main purpose of the present invention is to provide a social alarm system based on laser ranging, so as to solve the problem that the existing way of prompting to maintain a safe distance through voice broadcast has limited effect. [0005] The present invention is achie...
