Abstract

The invention discloses a CO2 concentration-based method for counting and managing pedestrians in a building evacuation passage, which comprises the following steps of: 1, monitoring personnel densityand CO2 concentration in the building evacuation passage in real time to realize real-time acquisition of data; step 2, processing the acquired data to obtain a curve graph of personnel density changing with time and a curve graph of CO2 concentration changing with time; step 3, carrying out function fitting on the obtained curve graph to obtain a quantitative relational expression of CO2 concentration changing along with time and a quantitative relational expression of personnel density changing along with time; 4, obtaining a quantitative relation between the personnel density and the CO2 concentration; and step 5, carrying out program compiling on the obtained quantitative relational expression, embedding the quantitative relational expression into a computer host, and finally completing statistics on the personnel density and the personnel flow in the pedestrian passage.

Description

technical field [0001] The present invention relates to the statistical technology of pedestrians in the entrances and exits of various public buildings, passageways, etc., and specifically relates to a method for counting and managing pedestrians in building evacuation passages based on CO2 concentration, which can be widely used in subways, stations, gymnasiums, exhibition halls, Pedestrian passages in shopping malls and other places, for people counting and pedestrian management. Background technique [0002] With the rapid development of economy, more and more people are pouring into cities. Many public facilities in the city, such as shopping malls, subways, exhibition halls, etc., will usher in peak pedestrian flow in a short period of time, especially during holidays. In recent years, there have also been stampede casualties caused by overcrowded pedestrian flow in various places. Therefore, it is very important to carry out real-time statistics and pedestrian flow m...
