Embodiment Construction

[0012] Such as figure 1 As shown, the present invention sets a signal detection mechanism, which is installed at the entrance and exit of a specific place where people counting is required. The signal detection mechanism includes two opposite and vertical installation panels 1 located on both sides of the entrance and exit, wherein a first infrared emitter 2 and a second infrared emitter 3 are installed on one of the installation panels, and the first infrared emitter Emitter 2 and described second infrared emitter 3 are spaced at a certain distance in the horizontal direction, and a certain height above ground; The second infrared receiver 5 relative to the infrared emitter; the first infrared receiver 4 and the second infrared receiver 5 are respectively connected with a serial server 6 through a switch circuit, and the serial server 6 is through a TCP / IP network 7 is connected with PC machine 8.

[0013] For example, at the entrance and exit of a meeting room or a library...

Abstract

The invention relates to an infrared bi-transmitting person counting method. One side of an entrance and exit of a special place is provided with two infrared transmitters, the other side is provided with two infrared receivers, the two infrared receivers are connected with a serial port server via switching circuits respectively, and the serial port server is connected with a PC via a TCP / IP network. The serial port server converts signals of the infrared receivers, the signals are transmitted to the PC via the TCP / IP network, the PC receives signals transmitted by the serial port server, if the signals are firstly received by the second infrared received close to the outdoor and later received by the first infrared receiver close to the indoor, the number of persons indoors is added by one; and otherwise, if the signals are firstly received by the first infrared receiver close to the indoor and later received by the second infrared received close to the outdoor, the number of persons indoors is reduced by one. Thus, the number of persons entering or exiting the room can be accurately counted.

Description

technical field [0001] The invention relates to a counting method, in particular to a method for counting and counting the number of people entering and leaving a specific place by using infrared rays. Background technique [0002] Chinese patent CN201010114826.2 discloses a method of head detection using a parallel multi-class classifier to determine the heads in the current image; track the determined heads to form the trajectory of the head target; The direction of the trajectory is used to count the flow of people. This method counts more accurately, but the cost is too high and the structure is complicated, which is not conducive to popularization. Contents of the invention [0003] The purpose of the present invention is to improve the above-mentioned scheme with high cost, and provide a people counting method with simple control, low cost, and high accuracy and reliability. [0004] Technical scheme of the present invention is: [0005] A method for counting the ...
