Device and method for detecting the number of people based on pressure sources

Abstract

The invention discloses a device for detecting the number of people on based pressure sources. The device includes a carrying platform, an installation plate, multiple pressure sensors and a processorused for analyzing signal transmission, the carrying platform is used for supporting multiple pressure sources, the multiple pressure sensors are laid on a surface of the installation plate; multiplesupport columns used for supporting the carrying platform are arranged on the surface of the installation plate; the processor is electrically connected to multiple sensors, and the processor is usedfor receiving, analyzing and processing information acquired by the multiple sensors. The device for detecting the number of people based pressure sources enables the pressure sensors arranged on thelower surface of the carrying platform to have a small amount of deformation through the pressure on the carrying platform, the pressure sensors then transmit the number of their received pressure sources to the processor, the processor analyzes, processes and calculates the transmitted information, and compares the transmitted information with two neighboring groups of data, and if an obtained result is in an error range, sends the processed data to a control terminal. The device realizes real-time detection for the number of people in a station and reasonable scheduling of school buses.

Description

technical field [0001] The invention relates to the technical field of management machinery, and more specifically relates to a device and method for detecting the number of people based on a pressure source. Background technique [0002] Our country has a large student population. According to statistics, the total number of students in various higher education schools in the country has reached 36.99 million. The large population has caused great pressure on campus management (especially safety management). In recent years, the continuous occurrence of campus accidents has aroused the general concern of the whole society on campus safety, among which traffic safety on campus is one of the main concerns. [0003] For colleges and universities in Chongqing ("Mountain City"), due to the large ups and downs of the terrain, most students will choose to take the school bus on their school trips. The demand for school buses is large. Therefore, the safe operation and optimal mana...

Problems solved by technology

[0004] Through the investigation of the operation of school buses in colleges and universities and the process of queuing and waiting for students, it is found that at the transportation stations set up in schools, some stations often have more people waiting in line, while some stations are basically empty. At the same time, there are situations where school buses run empty. Existence, only when the school bus driver sees this result, he will temporarily adjust the school bus dispatch according to the number of people, which often leads to long waiting time in queue, and the students have already left when the school bus arrives, resulting in low utilization of school bus resources; especially This phenomenon is especially serious during the beginning of school, commuting to and from get out of class, and during meals.

[0005] At present, there are several ways to detect the number of people at the site, such as weight measurement, camera measurement and mechanical measurement, but there are different defects in these methods; the detection method of weight measurement is often due to the weight of the person There are large differences, which lead to large measurement errors and low accuracy; the camera measurement method avoids the problems existing in the weight measurement method, and the detection is carried out by transmitting pictures through the camera, but the detection range of this method is limited, and the later image processing is cumbersome , and when the camera is blurred, the accuracy of the measurement is greatly reduced; the mechanical measurement method does not have the problems of the above two detection methods, but the mechanical measurement method has problems such as blocking the road and being unsightly
