Sensing carpet, method and method used for monitoring pedestrian flow density in public place

Abstract

The invention discloses a sensing carpet, a system and a method used for monitoring pedestrian flow density in a public place. The monitoring of the pedestrian flow density is realized through the communication between the sensing carpet and a monitoring terminal by taking the sensing carpet as sensing equipment of the pedestrian flow density. A sensing detection circuit of the sensing carpet mainly comprises a detection module, a communication interface and a plurality of compression detection devices arranged in the sensing carpet in arrays; the sensing detection circuit is simple in structure, low in cost and easy to realize; the sensing carpet can be paved in various public places at any time, can be used and installed immediately, and is very convenient to install, detach and move; and the monitoring terminal can be realized by any terminal with communication, data processing and display functions, can realize portable monitoring. The processing flow of the overall system is simple, the programming difficulties of software programming personnel are reduced, the hardware performance requirements on a sensing carpet detection module and the monitoring terminal are reduced, and both the manpower and resource cost of system development can be controlled effectively.

Description

technical field [0001] The invention belongs to the technical fields of public transportation system management and electronic information technology, and in particular relates to a sensor carpet used for monitoring the density of people in public places, a system using the sensor carpet and a monitoring method. Background technique [0002] Passenger hubs, stadiums, theaters, supermarkets and other large public places often have excessive concentration of crowds, which leads to safety accidents. Therefore, it is necessary to monitor the flow density of these public places in real time to facilitate management and avoid accidents. [0003] At present, infrared, laser sensing technology or video image analysis technology are mostly used to monitor the flow density of public places. For example, the Chinese invention patent "Automatic Passenger Counting Instrument" with application number 03115817.X uses infrared sensors to detect changes in the distance directly in front of i...

Problems solved by technology

For example, the Chinese invention patent "Automatic Passenger Counting Instrument" with application number 03115817.X uses infrared sensors to detect changes in the distance directly in front of it, and judges whether people pass by, thereby counting the number of people in the flow; but infrared sensors are very vulnerable The influence of light affects the detection and judgment of infrared sensors

At the same time, the Chinese invention patent "Entrance and Exit People Counter" with the application number of 200510025186.7 uses the image of the entrance and exit captured by the camera to analyze the image, uses the image recognition technology to identify which is the head in the image, uses the motion recognition technology to analyze the behavior of the personnel, and finally Statistical analysis of the number of people and calculation of crowd density; however, video technology has the disadvantages of complex equipment composition, high difficulty in algorithm development, cumbersome calibration and debugging, and high cost. The recognition success rate is not high, and the image recognition accuracy is also easily affected by light

In addition, the crowd density monitoring system based on infrared sensing technology and video image analysis technology has one thing in common, that is, the equipment in the system usually needs to be fixed and installed in advance, the application is not flexible, and it cannot be quickly set up and used in temporary public places
