Problems solved by technology

The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a master-slave cooperative control system in large-scale IC card manufacturing equipment. For writing COS data, the system uses concurrent reading and writing, and for personalized data, it is still Point-to-point, which can solve the problems of slow writing COS data packets and weak parallel processing ability in the current card making process, thus greatly improving the overall card making efficiency

Embodiment 1

[0058] A master-slave cooperative control system in large-scale IC card manufacturing equipment, such as figure 1 , including host, industrial Ethernet switch, database server, FIFO concurrent unit and card writing unit. Both the FIFO concurrent unit and the card writing unit are embedded microprocessor systems based on the Linux operating system. The host is an industrial PC, directly connected to the switch; the switch is externally connected to multiple FIFO concurrent units, multiple card writing units, and a database server for saving all data through the network port. One FIFO concurrent unit is connected to one network port of the switch, so multiple network ports of the switch can be connected to multiple FIFO concurrent units, and at the same time, the other end of one FIFO concurrent unit is connected to multiple card writing units. The output of the FIFO concurrent unit is connected to the FIFO memory module on each card writing unit. The system consists of the ho...

Embodiment 2

[0071] A master-slave cooperative control method in large-scale IC card manufacturing equipment based on the system in Embodiment 1. The master sends instructions to each slave through broadcast technology, so that multiple slaves can simultaneously accept instructions and execute corresponding actions according to the instructions. Task. The tasks include making cards and feeding back node status information (feedback the state of the current embedded processor system, including: whether it is making cards, the progress of making cards, heartbeat messages, error messages, etc.).

[0072] For the COS data APDU command, the host first reads the COS data packet of the IC card from the database server, takes out the COS data APDU command one by one from the COS data packet, and then broadcasts the COS data APDU command to the FIFO concurrent unit, and the FIFO concurrent unit will The data is sent to other card writing units in the same group to realize data sharing. The card wr...

Abstract

The invention discloses a master-slave cooperative control system and method in a large card making device of IC cards. The system comprises a master, a FIFO concurrent unit, a card writing unit, a database server and an industrial Ethernet switch used for interconnection. Each of the FIFO concurrent unit and the card writing unit consists of an embedded type processor system and the FIFO concurrent unit and the card writing unit are connected with each other through FIFO. The master serves as a main control end of the system. The FIFO concurrent unit and the card writing unit serve as slaves of the system. The master sends COS data APUD commands and personalized data APDU commands to the slaves by use of the broadcasting technology and the unicasting technology. According to the invention, a problem of slow data reading and writing speed in the current card making processes can be solved, so the whole card making benefits are greatly improved.

Description

technical field [0001] The invention relates to the technical field of IC card production, in particular to a master-slave cooperative control system and method in large-scale IC card production equipment. Background technique [0002] IC cards can be divided into logical encryption cards and CPU cards according to their organizational structure. The CPU card is also called a smart card. The integrated circuit in the card has a microprocessor, a memory and a chip operating system COS (Card Operation system). The CPU card equipped with COS is equivalent to a microcomputer, which not only has the function of data storage, At the same time, it has functions such as command processing and data security protection. IC cards mentioned below refer to CPU cards. Due to its inherent information security, portability, relatively complete standardization and other advantages, IC cards have been used more and more in fields such as identity authentication, telecommunications, banking,...
