Method and device for realizing adaptation of communication protocol of intelligent card

Abstract

The invention discloses a method and a device for realizing the adaptation of a communication protocol of an intelligent card. According to the technical scheme, the accuracy and the reliability of the adaptation of the communication protocol of the intelligent card can be improved without user participation. The main technical scheme comprises the following steps: acquiring operation state information about a currently configured communication protocol of the intelligent card; and converting the currently configured communication protocol of the intelligent card into a predetermined communication protocol when the configured communication protocol of the intelligent is determined not to match a terminal support communication protocol according to the operation state information.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for realizing self-adaptation of a smart card communication protocol. Background technique [0002] All communication systems are composed of two parts: software system and hardware system, and the communication protocol is a very important basic link in the software system. It can be understood as the key interface between software functions and specific hardware and the realization of software functions. Platform, based on the communication protocol, the communication system completes the transmission and interaction of information. [0003] In the field of smart card communication, there are currently many types of communication protocols, such as TypeA, TypeB, TypeC, and TypeD. Existing smart card chips can generally support TypeA and TypeB communication protocol types, and some can also support other types of communication protocols including Typ...

Problems solved by technology

Under normal circumstances, after the smart card chip jumps out of the standby state, a flag for identifying errors is set, but if the smart card receives a data frame different from the current protocol type but does not jump out of the standby state, the flag for identifying errors If the position is set, it will not be set, resulting in receiving multiple instructions different from the current protocol type and unable to adapt, thus affecting the normal communication of the user

[0007] In fact, in many practical applications, due to the electrical characteristics of the smart card chip itself and the differences in the specific environment (such as magnetic field strength, modulation depth, timing, etc.), the stability of the adaptive application is guaranteed solely by the characteristics and stability of the chip itself. is not enough, and often encounters situations where the adaptive success rate is very low

For example, if the same method is applied to different smart cards, it is likely that some smart cards can be self-adaptive due to differences in the characteristics of smart card chips, while others cannot; Ineffective

Similarly, it may also be due to the use of the environment, the same smart card can be adaptive in some environments, but not in other environments; the adaptive effect is good in some environments, but in others Adaptive effect is not good in the environment

[0008] To sum up, in the existing smart card communication protocol conversion method, the conversion effect is poor and the user operation is inconvenient for the mode that requires user participation; Problems with normal user communication
