Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a schematic flow chart of an offline control method for an access control device according to the present invention. An off-line control method for access control equipment comprises the following steps:
A. writing authorization information into the user card, wherein the authorization information comprises user codes, authorization validity periods, pass masks and card issuing times;
B. reading a user card, and judging whether the user card is legal or not through an equipment key; if the device keys are not matched, the user card is an illegal card, and the operation is ended; if the equipment keys are matched, the user card is a legal card, and the authorization information in the user card is read;
C. judging whether the authorization requirement is met or not according to the authorization validity period and the pass mask in the authorization information; if the authorization requirement is met, the next step is carried out; if the authorization requirement is not met, the authorization of the user card is illegal, and the operation is ended;
D. reading a user code in the authorization information, and judging whether the card issuing times corresponding to the user code is equal to the equipment storage times or not; if the card issuing times are equal to the device storage times, the user card is legal and authorized, and the access control device is controlled to be released; if the card issuing times are larger than the device storage times, the user card is a reissued card after loss report, and the access control device is controlled to update and store the card issuing times of the user card and release the card issuing times; if the card issuing times are smaller than the equipment storage times, the user card is a loss report card, and the access control equipment is controlled to issue an alarm.
In step a, the user card of the present invention uses a readable and writable smart card with an embedded memory module, such as a 13.56MHz M1 card or a CPU card, and writes the user code, the authorized validity period, the pass mask code, and the card issuing times into the memory module of the user card through a card writing device. The card writing equipment is matched with the offline access control equipment, and each user needing card issuing is numbered, and the number corresponds to the storage unit of the offline access control equipment.
In the step B, the off-line access control equipment reads the user card, verifies whether the authorization of the personnel is legal or not in the reading process, and specifically judges whether the user card is legal or not through the equipment key; if the device keys are not matched, the user card is an illegal card, and the operation is ended; and if the equipment keys are matched, the user card is a legal card, and the authorization information in the user card is read.
In step C, the present invention determines whether the authorization requirement is met according to the authorization validity period and the pass mask in the authorization information, where the pass mask is a special pass code of the offline access control device, and the pass mask is specific on an item, for example, if there are 6 channels in the community gate, the pass mask of the 6 channels is a 1.
In step D, when the authorization information meets the authorization requirement, the offline access control device reads the user code of the user card and compares the number of times of issuing the card by the card storage module, and there are three cases in comparison:
1. the card issuing times stored on the offline access control equipment are equal to the card issuing times stored under the card storage module; if the situation is a legal user, the offline access control equipment outputs a door opening signal;
2. the card issuing times stored on the offline access control equipment are less than the card issuing times stored under the card storage module; in the case, after a user loses a card, the card is supplemented, the offline access control equipment updates the stored card sending times of the user, and simultaneously, the offline access control equipment outputs a door opening signal;
3. the card issuing times stored on the offline access control equipment are greater than those stored under the card storage module; this situation is a card that has been reported lost, the card is illegal, and the device sends an alarm signal.
