Problems solved by technology

Some people also try to place the detector on the side of the moving direction of the person, use the Fresnel lens to detect the facial signal of the human body, and identify the moving direction of the human body; some people arrange the sensors in a matrix to identify the moving direction of the human body through the sensor response sequence, but these The human body information collected by the method is messy. Even after processing, the human body signal will not have strong regularity, so the sensitivity and accuracy of recognition are not high, and there is still a big gap from the actual application.

Embodiment 1

[0026] A method for counting people based on an embedded system, comprising:

[0027] a. Signal acquisition: place the detector of the signal acquisition device on the top of the human body passing area, the modified optical system, the infrared pyroelectric sensor only responds to the human body signal in the limited detection area, and transforms the collected irregular signal is a regular signal recognized by the processor;

[0028] b. Signal processing: After inputting the identifiable regular human body infrared signal into the core processor, use the fuzzy recognition algorithm to identify the moving direction of the human body, perform real-time statistics of the number of people, and automatically store them in the external memory;

[0029] c. Use the USB controller that comes with the embedded microprocessor to build a system USB transmission interface, and the user can transfer the data of personnel information in the memory through the USB interface.

[0030] In th...

Abstract

The invention relates to personnel counting method and equipment based on an embedded system. Information collected by adopting the traditional mode for collecting human body information is messy. The method comprises the following steps of: collecting signals: placing a detector of a signal collecting device at the top of a human body passing area, only responding human body signals limited in a detection area by an infrared pyroelectricity sensor through a reformed optical system, and converting the collected irregular signals into regular signals which can be identified by a processor; processing the signals: after the identifiable regular human body infrared signals are inputted to the core processor, indentifying the human body moving directions by adopting a fuzzy identification algorithm, and then counting personnel quantity in real time and automatically storing in an external memory; and establishing a system USB transmission interface by utilizing a USB controller of an embedded microprocessor so that users can transfer the data of personnel information in the memory through the USB interface. The invention is used for counting personnel in messy streams of people.

Description

technical field [0001] The invention relates to a system which utilizes human body infrared signals to identify the moving direction of people and counts and counts the number of passing people in real time, belonging to the field of electronic detection and signal processing. Background technique [0002] At present, the statistics of the number of personnel in places with personnel flow at home and abroad still adopt the traditional manual operation statistics method in most cases. Some people also try to place the detector on the side of the moving direction of the person, use the Fresnel lens to detect the facial signal of the human body, and identify the moving direction of the human body; some people arrange the sensors in a matrix to identify the moving direction of the human body through the sensor response sequence, but these The human body information collected by the method is messy, and even after processing, the human body signal will not have strong regularity,...
