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...

Embodiment Construction

[0036] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] In this embodiment, a temporary exhibition site is taken as the implementation object to illustrate the sensor carpet, system and monitoring method for crowd density monitoring in public places of the present invention. There are three exits at the temporary exhibition site. In order to ensure the safety of the flow of people, it is necessary to monitor the flow density of each exit to avoid safety accidents such as overcrowding and stampedes. However, the opening time of the temporary exhibition is relatively short. If infrared and video monitoring equipment are used , not only the technology is complicated and the investment is high, but also the installation and commissioning time is relatively long, which affects the passenger flow of the exhibition site, and it needs to be dismantled soon after the installation, whi...
