Embodiment Construction

[0022] The invention is used in the bus intelligent management information service system. Passengers are the service objects of the bus, and their distribution in time and space plays a decisive role in the dispatching management of the bus, so it is very important to know the passenger flow on the line in real time for the bus dispatching management. The statistics of the passenger flow of public transport vehicles mainly include two aspects: the number of boarding and the number of getting off. By detecting the number of people getting on and getting off, the real-time number of people on board is calculated.

[0023] Such as figure 1 As shown, the present invention includes human body infrared sensor array 1 and infrared reflective switch array 2 placed above the upper and lower car doors, multiplexers 3, 4, 6, human body infrared sensor conditioning circuit 5 and CPU control circuit 7, Among them, above the door of the bus, there is a human body infrared sensor and an i...

Abstract

The invention discloses a bus passenger flow real-time counting method, above a bus door, vertically downward equipped with a human body infrared sensor-infrared reflecting switch array, each point of the array is composed of a human body infrared sensor and an infrared reflecting switch bound with each other; the human body signals sensed by the array are amplified, filtered and compare- converted through multichannel selector and signal conditioning circuit into electric pulse signals, which are read in from I / O ports of a CPU, and the data is stored into a data memory, and the CPU judges the directions of getting on and off and counts the number of passengers getting on and off by a certain algorithm according to the number of read array-sensed pulses and the read pattern, and finally the serial port of the CPU sends the number of counted passengers getting on and getting off at each station, to a vehicle terminal or control center, which real-timely counts total number of passengers.

Description

technical field [0001] The invention discloses a method for real-time counting of bus passenger flow, which is suitable for counting the number of people getting on and off at each bus stop and the number of passengers carried in real time. Background technique [0002] In order to effectively count the passenger flow of buses in real time, certain sensing elements must be used to sense the signal of the human body when passing the door. At present, the methods that can obtain the human body signal and convert it into an electrical signal include pressure sensors and human body infrared sensors. , infrared photoelectric switch, camera and bus IC card, etc. The difficulty of bus passenger flow is that there are many irregularities or abnormalities in which the human body passes through the doors. The main manifestations are: the height and weight of the human body are different, the speed of the human body movement is different, and the human body gets off from the upper door...
