Embodiment Construction

[0009] The working principle of the preferred embodiment of the control method of the multi-card system of the present invention is as follows:

[0010] When a card is inserted into a multi-card system, the inserted card detects the working status of similar cards. As long as it is detected that a card of the same type is in an active state, the inserted card is set to a waiting state, and the information that it is in a waiting state is transmitted to the control card. If no activated card of the same type is detected, the plug-in card cannot determine its own working state only through communication with the card of the same type. At this time, the plug-in card sends a request to the control card for inquiring about the working status of similar cards, and records the time t1 when the request is sent for the first time. In this embodiment, for a multi-card system including n types of cards, an n-dimensional array T1[n] is set, which is used to store the maximum request dura...

Abstract

The invention provides a control method of a multi-card system, comprising the following steps: after being inserted into the multi-card system, a card detects the working modes of similar cards; if activated similar cards are detected, the inserted card is set to be in waiting mode; otherwise, the inserted card puts forward a request of inquiring the working modes of the similar cards to a control card; the control card feeds the working modes of the cards similar to the inserted card back to the inserted card; the inserted card determines own working mode after receiving the working modes of the similar cards; if the inserted card does not receive the feedback information from the control card within preset time after putting forward the request to the control card, the inserted card is activated. The control method of the multi-card system can avoid system information spillover because the cards are mis-activated during abnormal connection among cards and improve the stability of the system.

Description

technical field [0001] The invention relates to a control method for a multi-card system, in particular to a control method for the working state of cards in the multi-card system. Background technique [0002] The multi-card system regulates multiple different types of cards through one control card. Different types of cards are independent of each other, and each type of card contains multiple cards of the same type. This can not only increase the stability of the system, but also realize different services and increase the flexibility of the system. Generally speaking, only one card of each type of card can be activated. If two or more cards of the same type are activated at the same time, system information will overflow. [0003] When the card is inserted into the multi-card system, it detects the working status of the same card. As long as one card of the same type is detected as being activated, the card will be set to a waiting state; if no card of the same type is ...
