Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments to assist understanding of the invention. The method used in the utility model is a conventional method if no special regulation is provided; the raw materials and the apparatus used are, unless otherwise specified, conventional commercially available products.

Shown by fig. 1-4, the utility model provides a simple and easy advertisement machine of taking people's flow monitoring, it includes backlight unit 1, and backlight unit 1's bottom is equipped with light sensor, and light sensor includes infrared lamp 2 and infrared receiver 3, and infrared lamp 2 and infrared receiver 3 pass through the switching subassembly to be fixed in backlight unit 1's lower part. Monitoring statistics is carried out to the flow of people who comes and goes through setting up light sensor, conveniently monitors the publicity effect of advertisement machine, with two unifications of advertisement machine and flow of people statistics function.

Specifically, the switching assembly comprises a PCB (printed circuit board) 4, a fixing support 5 and a metal protection cover 6, the infrared lamp 2 and the infrared receiver 3 are sequentially fixed at the front end of the PCB 4 in parallel, and the photosensitive parts of the infrared lamp 2 and the infrared receiver 3 face towards the same direction as the liquid crystal screen of the advertising machine. Fixed bolster 5 is L shape, and the front end fixed connection of screw and PCB board 4 is passed through to the one end of L shape hem, and it has the notch to dodge infrared lamp 2 and infrared receiver 3 to open with the L shape hem of one side, and the other end of L shape hem passes through the bottom fixed connection of screw and metal protection cover 6, all fixes infrared lamp 2, infrared receiver 3, PCB board 4, fixed bolster 5 in metal protection cover 6.
