System and method for counting people based on grid-type intelligent identification unit

Abstract

The invention provides a fast, efficient and low-cost head counting system based on grating-type intelligent recognition units. The system comprises a control terminal and at least two grating-type intelligent recognition units. Each grating-type intelligent recognition unit includes a hollow frame; two side walls of the hollow frame is provided with a first infrared sensor module and a second infrared sensor module; the first infrared sensor module and the second infrared sensor module are arranged along the traffic direction at intervals; the bottom plate of the hollow frame is provided with a pressure sensor; the hollow frame is also provided with a microprocessor; and the microprocessor of each grating-type intelligent recognition unit is in communication connection with a control terminal. The invention has the following beneficial effects: dual detection of infrared sensors and pressure sensor is employed, and the infrared sensors are in reasonable position layout, and two groups of infrared sensor modules are set up for self correction, so as to effectively prevent false triggering and realize high accuracy and low cost.

Description

technical field [0001] The invention relates to a system and method for counting people based on a grid type intelligent identification unit. Background technique [0002] For the occasions where the police need to carry out regular counting of the number of people, in order to prevent the escape of the supervised personnel, such as prisons, detention centers and drug rehabilitation centers, etc., the regular, regular or irregular, heavy manual counting method is time-consuming and laborious, which greatly increases In order to manage costs and police workload, providing a fast, efficient and low-cost personnel counting system and counting method has become a difficult problem to be solved in these fields. At present, some people propose to carry out inventory by setting a radio frequency tag (active RFID) on each person in the supervised population. Due to the large environmental interference and high system cost, it is difficult to implement and it is difficult to populari...
