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.
