Electronic parking charge system not the three key technologies

2023-09-08 00:00:00
electronic parking charge system is not often said ETC (ElectronicTollCollection), it USES radio frequency identification technology, the toll booth to install card reader, the vehicle assembly of the radio frequency card, so toll station in a certain range can be carried out on the vehicle identification, and automatically on the binding of IC card or bank account in advance to deduct the corresponding cost, need not stop payment.Because of its no artificial cost, no parking charge, charge for quick and easy, widely used in highway charging, and bridge (tunnel).

not achieve parking charge system has three key techniques: recognition technology, data transmission and database management, we detail below.In addition, here as an aside, electronic parking charge system is the key to the charge, and is not without a stop.

1. The vehicle identification

no parking charge for electronic technology using radio frequency identification technology, the vehicle identification system consists of rf card reader and, at the toll booth to install card reader, the vehicle configuration of the radio frequency card, exchange data through wireless, between them for identification.If someone will ask, radio frequency card without power identify not to come out, how to do?There’s no need to worry, because the radio frequency card use is passive radio frequency card, without power supply, it through the way of inductive coupling, microwave energy can be transformed to work energy.

2. Data transmission

security is the key of data transmission.In the process of the recognition of vehicle, namely data acquisition phase, rf technology transmission speed quickly, only a fraction of a second, and because the microwave radiation, low frequency, the security is guaranteed.In the process of transmit the data to the data center, we adopt the way of encryption is dedicated, ensure the safety of data transmission.

3. Database management

in a no parking charge system, the data center has two parts: the system data management unit and bank data management unit.System data unit is mainly management vehicle related data collection, the cost of operation, system security management, vehicle tolls split, the related report management, etc.;Bank data management unit with radio-frequency card card is dealt with, mainly to undertake withholding tolls and other services.Database management is quite complicated, here we are simple, no parking charge system USES is prepaid way, users should be stored in the radio frequency card cost, through the toll station automatically debit card.At the same time can also with bank card, credit card binding, such as consumption in advance, the system periodically and bank reconciliation.
