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

A device for recording the passanger throughput of bus at each stop by ultrasonic detector is composed of a sensor (ultrasonic detector) and a signal processing circuit. Said ultrasonic detector is composed of an ultrasonic transmitter and an ultrasoic receiver which is connected via A / D converter to the signal processing circuit connected to memory and card reader.

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...
