Mobile Internet parking management method and system

InactiveCN105825707AEasy dockingRealize data integration managementTicket-issuing apparatusReservationsPaymentSystem maintenance
The present invention relates to a mobile Internet parking management method and system. The mobile Internet parking management method includes the following steps that: a server receives a reservation parking request sent by a client and generates reservation information according to the reservation parking request and allocates a reserved parking space; when a reservation automobile arrives at the entrance of a parking lot according to a reservation, the server searches the reservation information according to automobile information uploaded by the entrance of the parking lot and instructs the entrance of the parking lot to carry out parking according to the reservation information; when the automobile leaves, the server calculates parking fees of the automobile and sends fee payment information to the client so as to prompt the user to pay the fees; and after the server receives online fee payment of the client, a current parking process is terminated. With the mobile Internet parking management system of the invention adopted, the user can carry out registration and make a reservation in advance, the registration and reservation are directly recorded through the system, an unoccupied parking space is reserved; and when an automobile is being parked, the system automatically identifies whether the automobile is a reservation automobile. With the mobile Internet parking management method and system adopted, a situation that a large number of parking space guidance and automobile searching devices are installed in a parking lot can be avoided, investment cost and system maintenance cost can be saved.

Vehicle remote diagnostic system and diagnostic method

The invention proposes a vehicle remote diagnostic system and diagnostic method. The system includes a configured device, an in-vehicle diagnostic unit and a remote diagnostic unit. The in-vehicle diagnostic unit is connected with the remote diagnostic unit through a wireless communication network. The in-vehicle diagnostic unit includes a vehicle-mounted information entertaining system, an in-vehicle bus and the wireless communication module. The configured device is connected with the vehicle-mounted information entertaining system through the in-vehicle bus. The vehicle-mounted information entertaining system is used for receiving a diagnosis command of a user, acquiring diagnostic data and sending diagnostic data packets to the remote diagnostic unit through the wireless communication module and at the same time receiving and displaying diagnostic result data transmitted back by the wireless communication module. Through integrating a diagnostic module into the vehicle-mounted information entertaining system which is necessary for a vehicle, the vehicle remote diagnostic system and diagnostic method avoid outfitting and installation of a single diagnostic device and reduce the cost of the whole vehicle. Diagnoses can be realized through simple operations on the vehicle-mounted information entertaining system so that professional requirements for the vehicle diagnoses are reduced and at the same time, remote-diagnosis performance and efficiency are improved greatly at the same time.
