In the above embodiment, the smart card management apparatus includes the main controller 1, the serial peripheral interface control module 2 in communication connection with the main controller 1, and the plurality of card strip control modules 3 in communication connection with the serial peripheral interface control module 2, each card strip control module 3 is in communication connection with the plurality of smart cards 4, the main controller 1 sequentially sends access requests to the corresponding card strip control modules 3 through the serial peripheral interface control module 2, and then reads the execution results stored in the card strip control modules 3 in a polling manner, so as to implement parallel processing of the plurality of smart cards 4, thereby implementing management of a large number of smart cards 4, and improving the processing efficiency.
In a possible implementation manner, the serial peripheral interface control modules 2 are respectively in communication connection with the main controllers 1 through serial peripheral interface buses and control buses, and each main controller 1 can be connected with a plurality of serial peripheral interface control modules 2 through the serial peripheral interface buses 6, so that parallel processing of batch access requests is realized. As an example and not by way of limitation, as shown in fig. 2, the first control unit 10, the second control unit 20, and the third control unit 30 are respectively connected to the serial peripheral interface bus 6 through one serial peripheral interface control module 2, so that multiple smart cards 4 can be controlled, and a single master controller 1 controls multiple smart cards 4, thereby reducing the device deployment cost and improving the deployment efficiency. The second control unit 20 and the third control unit 30 are identical in structure to the first control unit 10. Meanwhile, the signal transmission speed of the serial peripheral interface bus can reach 18Mb/s at most, so that the main control 1 can send access requests to all the card strip control modules 3 and read execution results within the time when the intelligent card 4 finishes processing a single command, and the communication efficiency is improved.

Therein, the command or query flag may take two values, 0xaa and 0x00, respectively, for identifying the execute command and the query command, respectively. The command sequence number is the unique identifier of the command, and is used for finding out that the command with the same sequence number corresponds to the command when the command is received. The command length is used to indicate the number of bytes of the command. The SIM card position is the position of the SIM card in the card strip, for example, 0 to 7, and the card strip control module 3 finds the corresponding SIM card according to the SIM card position. The read/write card command is the command content. The CRC check is used for checking all data of the command to ensure the correctness of the command.

The main controller 1 comprises a service layer and a communication layer, after the main controller 1 obtains the access request of the intelligent card, the service layer starts one or more threads according to the concurrent number of the services, decomposes the services into a series of commands for the card and sends the commands to a sending queue according to the access request of the intelligent card, and simultaneously searches whether a response is received from a receiving queue at regular time. The communication layer enables a data sending thread and a data receiving thread to send and receive commands. When detecting that the sending queue is not empty, the data sending thread sends a command of the sending queue to the card stripe control module 3 through the serial peripheral interface control module 2. The card stripe control module 3 puts the received commands into a command processing queue and sequentially executes the commands. After the command execution is completed, the card strip control module 3 sends command response information or command error information according to the command execution result, and moves the command response information into the SPI data sending area to wait for sending. The main controller 1 searches whether a command to be received exists from the receiving queue in a timing query mode, and if the command to be received exists, sends a query command according to the command serial number, retrieves all response information and realizes efficient read-write operation.
In one possible implementation, the spi control module 2 further comprises a signal driver 7, e.g., a signal amplifier, connected between each first switch 21 and the main controller 1, so that signals can be enhanced and signal interference can be reduced, so that the spi bus 6 can be transmitted at a high rate further, so that the device size can be enlarged and more smart cards 4 can be supported.
