Ultrasonic sensor array type automatic people counting detection system

Abstract

The present invention relates to an ultrasonic sensor array type automatic people counting detection system, which comprises an ultrasonic sensor array type automatic people counting detection system motherboard arranged on a support vertical surface, an ultrasonic transmitter array set and an ultrasonic receiver set, wherein the ultrasonic transmitter array set and the ultrasonic receiver set are arranged on an area support plane above people, and the ultrasonic sensor array type automatic people counting detection system motherboard is respectively connected with the ultrasonic transmitter array set and the ultrasonic receiver set. According to the present invention, the microprocessor is adopted as the core, such that the exact number and the exact position of people in the area can be rapidly and automatically detected, the conditions that the people come in the area and move away from the area and the people movement condition within a certain time can be subjected to automatic statistics, and the system can be used for detection of the number of the waiting people at the bus station, detection of the number of the people waiting for elevators outside the elevators in high-rise buildings, detection of the number of people in elevators and other vehicles, detection of the conditions that people come in the area and move away from the area in the area, and other occasions.

Description

technical field [0001] The invention relates to an automatic detection system, in particular to an ultrasonic sensor array type automatic detection system for the number of people. Background technique [0002] At present, some crowd detection systems have been applied to the detection of the number of passengers in buses and the detection of the number of people waiting in elevators. Among them: the detection speed of the crowd detection technology using the principle of image recognition is relatively low, and the detection equipment is complicated; the detection system error using the infrared human body sensor is relatively large; Due to limitations such as small area, the detection error is also relatively large, and the optical detection method also has the disadvantage of being easily interfered by the external light environment. [0003] Although some ultrasonic array measurement systems currently exist, which are installed on mobile devices, such as for mobile robo...
