Abstract: The present invention provides an intelligent charging system and method for use in a parking lot. The system comprises a detecting unit, an on-board unit and a corresponding means of payment. The on-board unit is disposed on a vehicle and configured to acquire a parking time parameter, derive a parking fee according to the parking time parameter and a rate parameter stored in the on-board unit, and deduct the parking fee from the means of payment. The detecting unit is configured to, through information interaction with the on-board unit, determine whether the on-board unit operates normally. The present invention can be used to reduce the investment cost and improve the monitoring management of public parking lots.

Abstract: The present invention relates to the smart card field, and more specifically to a smart card operating system and method, to avoid the failure of non-contact communication of the smart card operating system resulting from its inability to obtain the information of access to the non-contact field in the prior art. In the present invention, the communication state control module detects whether the smart card operating system enters and/or leaves the a non-contact field; and sets the communication state of the non-contact communication module of the smart card operating system based on the detection result. By applying the technical scheme of the present invention, we can avoid the communication failure which results from the non-contact communication module inability to respond properly to the inquiry from the non-contact terminal when the smart card operating system re-enters the non-contact field.

Abstract: A dual usage smart card of CPU and logical encryption and its data synchronization method. Said method comprises that a CPU command processing module controls an accessing control module for the logical encryption storage region to read the data in the logical encryption storage region to a data format conversion module; said data format conversion module transmits the data to the CPU control storage region; the CPU command processing module controls the CPU control storage region again to transmit the data of CPU card to the accessing control module for the logical encryption storage region through the data format conversion module; and said accessing control module for the logical encryption storage region writes the data of CPU card into the logical encryption storage region.

Abstract: An equipment and method to implement the adaptive functions of communication protocols are provided so that the smart card operation system can adaptively select the corresponding communication protocol according to that of the terminal. The equipment includes: a communication protocol setting module; a communication protocol detecting module; a communication protocol selecting module. The method includes: setting communication protocol for the smart card operation system; judging whether the communication protocol type of the smart card operation system is identical with that of the terminal; if not identical, selecting communication protocol for the smart card operation system. Therefore, the communication protocol of the smart card operation system can be adaptively selected according to the protocol of the terminal.

Abstract: The present invention relates to a smart card operating system and process, when the system is powered on, the operation mode selecting module judges the power supply manner for the system, and selects a first operation mode when the power is supplied from a non-contact power source, and selects a second operation mode when the power is supplied from a contact power source; in the first operation mode, a command processing module separately processes a non-contact command received by a non-contact communication module; in a second operation mode, the command processing module processes in parallel a contact command received by a contact communication module and a non-contact command received by a non-contact communication module. The smart card operating system is able to support simultaneously a contact communication and a non-contact communication in use of the technical solution of the present invention, which greatly enhances the application flexibility of the smart card.
