Close distance visual blind area human body detection method, device and related methods

Abstract

The invention discloses a close distance visual blind area human body detection method. A hardware system comprises a main control end and detection terminals, a wireless communication network is formed and deployed on a service object or an adjacent area totally or partially, at least one detection terminal comprises a human body detection sensor module, the main control end receives detection data sent by the detection terminals through wireless communication modules of the detection terminals through wireless communication modules of the main control end, and detection results are shown on showing modules after the data are processed. Functions of the main control end and the detection terminals can be integrated, detection capacity and energy consumption are improved further, and wireless communication modes of the method are replaced by wired communication modes totally or partially. The invention further discloses a detection device manufactured according to the method. The detection device adopts a ZigBee chip and uses a light-emitting diode (LED) lamp and a horn to show the detection results. The invention further discloses a deploying method of one electricity-saving working mode and two kinds of detection terminals and a detection data analysis method.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and also belongs to the field of traffic and security, and in particular relates to a method and a device for detecting a human body in a near-distance visual blind spot. Background technique [0002] Near-distance blind spots are very common in daily life. The most typical example is the near-distance blind spots of motor vehicles. There was a case reported in the media that a father crushed his own child to death. The young child secretly followed the father to the car. In addition to the above situation, large vehicles have a more dangerous situation, that is, when turning, because of the inner wheel difference (the difference between the turning radius of the inner front wheel and the turning radius of the inner rear wheel when the vehicle is turning) Poor) is relatively large, forming a blind spot in the rear view, and related accidents are seen in the media from time to time....

AI Technical Summary

Problems solved by technology

[0007] The present invention aims to solve the problem of life and health dangers to people caused by near-distance visual blind spots. In the present invention, short-distance refers to the range within 15 meters from where danger may occur. Visual blind spots include absolutely invisible blind spots caused by occlusion. , also includes relatively invisible blind spots caused by the limited natural visual range and the influence of attention factors
