Problems solved by technology

[0004] Method 1 is a temporary, but relatively accurate counting and statistics method. However, this manual method has a large workload, high cost, and is difficult to use for a long time. Method 2 can only calculate the total number of passengers who do not hold a bus monthly pass for one bus per day. The number of people, the number of people getting on and off at each platform and the number of people holding monthly bus tickets can be calculated. Method 3 can calculate the total number of passengers who do not hold bus IC cards on one bus a day and the number of different IC card holders on each station. Quantity, you can't get the number of passengers who put coins on each station, and you can't get the number of people getting on and off at each station

Abstract

The invention relates to a device for automatically monitoring passenger on bus in each stop at each time period by infrared detector. The sensors output ends are connected to A / D converter in the signal detector. The output end of the A / D converter is connected to the digital signal processor whose output end is connected to signal processor in the signal processing circuit. The signal processoris connected to memory as well as emitter-receiver and IC card reader. The infrared sensors are installed on the door frame side by side. 'RXD, TXD' ends of single-chip IC in signal processor are connected to the signal wire for reading card in the card reader devices on the bus.

Description

1. Technical field: [0001] The utility model relates to a method and a device for automatically recording the number of passengers on and off a bus, in particular to a method and a device for automatically recording the passenger flow of a bus at each station and at each time period. 2. Background technology: [0002] With the acceleration of urbanization and the improvement of people's living standards, the urban population and vehicles, especially the number of private cars, have increased sharply. Traffic jams are very serious, and urban traffic problems have become increasingly prominent. Therefore, many people of insight strongly advocate the vigorous development of urban public transportation to ease the traffic pressure in the city and reduce urban pollution. [0003] But how to carry out scientific public transportation planning, how to arrange bus routes, and passenger flow distribution data are the foundation. There are mainly three methods for the statistics of t...
