Intelligent infrared people counter bus passengers counting  


SF-TK   bus passenger Counting system can automatically, intelligently, accurately gather the number of passengers getting on / off,time statistical control for passenger flows at every station,and the information detection managementsystem of vehicle operation analysis.


Product Description


SF-TK  bus passenger counting system includes tranducers,door switch and processor.equipments need to be installed according to the size of bus door,in general,there are one processor,one door switch,3 tranducers in front doors, one processor,one door switch,2 tranducers in rear door. Tranducers are responsible for catching information of passenger passing and sending to processor.

Door switch is for inspecting the state of bus doors,door switch is mounted on the door frame to check the state of door,start or close detecting function of processor.when the magnetic departs from door switch,door opens,the indicator goes off,at this time,processor starts counting function.otherwise,the indicator flashes. processors are for receiving information from tranducers and counting.

1.Operating Principle


Respectively install the vehicle-mounted passenger flow counter and baffle-board at the two sides of the car door. When there no passengers going on and off, the infrared signal launched by the built-in launcher of the vehicle-mounted passenger flow counter reflects and is received through baffle-board and the infrared signal strength is strong enough and can penetrate through the glass of car door. Therefore, the vehicle-mounted passenger flow counter and baffle-board can be installed behind the glass of car door, but it’s necessary to purchase door contact switch component separately to be used in case of errors arising from the activity of filter car door. When the passengers keep out the infrared signals reflected by the baffle-board while getting on and off, the vehicle-mounted passenger flow counter will count the number of the direction of getting on or off once according to the direction that the passengers keep out the infrared signal. The data will be displayed through LCD display screen according to the set direction.




2.Installation Requirements




2.1. The vehicle-mounted passenger flow counter is installed at one side the car door that is as high as 800-1300mm away from the footboard of the car door; in case that the car door is equipped with the multi-step footboard with large slope, it is necessary to reduce the installation height. It should be installed according to the actual gesture chest height of the passengers when getting on the car, but it should not be installed in the position for the fixed installation with the scope of the activity of the door leaf of the car.




2.2. The distance between the baffle-board and the passenger flow counter should not longer than 3000mm.




2.3. In case that the car door footboard refers to the stair-type footboard, it is necessary to appropriately reduce the installation height to ensure the passenger flow counter is appropriately in the position of the chest of passengers when they get on the car and their body bends forward.




3. Installation of baffle-board


After completing installation of passenger flow counter, install baffle-board according to the position corresponded by that of passenger flow counter. Baffle-board is applied to reflect the infrared beam launched by the passenger flow counter in order that the passenger flow counter could detect the infrared beam signal. The infrared beam is invisible light. Whether the baffle-board is in the correct position can be determined according to the two LD indicator lamps on the panel, which is as shown by the following Fig.:


When baffle-board is within the scope of infrared beam, the two action indicator lamp on the passenger flow counter panel will be off, through which whether the baffle-board is in the correct position can be determined.





4. Count testing




When the passengers get on the car and pass by the testing side between the passenger flow counter and baffle-board, the counting indicator lamp of the passenger counter will flash once and the counting indicator lamp will indicate according to different walking directions.
