For the flat fare system, before the system is started, the bus validator has downloaded a level of charge amount (the card is set when the card is issued), and the passenger pays the same fare no matter where the passenger gets on the bus.
When the passengers get on bus, the card is shaken in the sensing area in front of the device. After the bus validator detecting the card, the card legality is first verified. After the verification is passed, the fare is deducted. When the above operation is completed, and the fare collection is completed for the passenger and he can take the bus.
The bus validator stores all transaction records that occur within one business day, and sends all transaction records to the server backend through the collector within a specified time.For the zonal fare system, a bus validator+ a driver keyboard mode can be used: the driver is equipped with a special keyboard for setting the deduction amount of the "bus validator". The keyboard and the "bus validator" are connected by physical lines. When the deduction amount of the "bus validator" needs to be changed, the driver controls through the keyboard. The way to tap card when get on and off the bus: mark the card when get on bus and compare the mark to deduct fare automatically when get off the bus. Mainly consists of: GPS automatic bus announcer, bus validator host device, bus validator sub-device, the working principle and process are as follows -1, install the host and the sub-device separately at the front and rear vehicle door"; 2, collect the GPS information of each station in advance with GPS automatic bus announcer; 3. set the price between each station in the system software, and upload the price standard to the “bus validator”. "; 4, passengers on the bus and tap card on the host device to mark the card; 5, "GPS automatic bus announcer" automatically change station, and trigger the "bus validator" to identify the site to change the fare; 6, When you get off the bus, tap card on the sub-device . After the system compares the results automatically, the bus fare is deducted from the IC card.
