The information processing module 1 is internally provided with a time calculating unit 1 a.
The information processing module 1 is also connected with a storage battery 1b, and the access control system can be normally used under the condition of power failure. The use in case of power failure is specifically: the storage battery ensures the synchronism of the time computing unit 1a and the time line of the mobile terminal 2, after the access control system receives the password input by the user, taking the time of the access control system as the main time, the time calculating unit 1a takes the integral time of a certain minute of a certain time of a certain day of a certain month of a certain year as a time node algorithm (the default takes 10 minutes as a time node, namely 00, 10, 20, 30, 40 or 50), meanwhile, a rounding algorithm is adopted (rounding here means rounding for 10 minutes, such as the current time: 12:01, 12:09, rounding for 12:00, such as 13:22, 13: 23, rounding for 13:20, and the like), the pass password (the password defaults to 6 digits, and the password digits can be modified according to the use requirement) corresponding to the time period is dynamically calculated through the unique number of the access control system for comparison, and the pass can be performed if the pass password is completely matched; considering that a certain error exists in the time of the access control system or the mobile terminal 2, a certain time difference (the time difference is 1-10 minutes) exists in the process of allowing the user to generate the password and input the password.
When the access control system determines the current hour to be 10 minutes, the previous 10-minute hour and the next 10-minute hour of the 10-minute hour are taken (for example, the hour is 13:20, the previous 10-minute hour is 13:10, and the next 10-minute hour is 12:30), and if one of the two calculated passwords is matched with the received password, the access is allowed. (default round 10 minutes, for subsequent functional needs, integer values of 1, 5, 20 minutes, etc.).
The working mode of the invention is as follows: before use, a database and a notification information generation rule corresponding to a service classification result are preset in the information processing module 1; the information processing module 1 is networked, a target user inputs the identity identification information of the target user in the access control system through the mobile terminal 2 or through an access control system manager, a database of the information processing module 1 records the service data of the target user, then the information processing module 1 extracts the service data, and the target user is classified and calculated through rules to obtain the service classification result of the target user; the classification result comprises a common user and a management user; the common user only has the right of opening the entrance guard electronic lock 6 in the entrance guard system to enter and exit aiming at the common target user, and the management user has the right of modifying and controlling the entrance guard system aiming at the manager.
After the information processing module 1 classifies the service classification result of the target user, a two-dimensional code or a door-opening password is automatically configured and generated to the target user holding the mobile terminal 2 through an APP or a small program on the mobile terminal 2 according to the difference of the target user, and an access control system manager manufactures an IC card for the target user through a card writer; the data information in the door opening password, the two-dimensional code and the IC card is encrypted data, and the data information comprises passage authority, passage valid period, the number of buildings of a target user and floor number information; and the target user only needs to open the APP or the applet for the first time to obtain the door opening password and the two-dimensional code data from the information processing module 1, and then the door opening password and the two-dimensional code data are automatically stored locally, so that the door control electronic lock 6 in the door control system can be opened by normal use even if the mobile terminal 2 does not have a network in the subsequent use process, the bidirectional offline operation is realized, and the defect that the door control electronic lock 6 in the door control system cannot be normally opened due to poor network signal quality and unstable signal connection is effectively overcome. In order to prevent the target user from unlimited passage of time by modifying the mobile terminal 2, the time limit is specially made on the electronic key (digital password and two-dimensional code) in the information processing module 1 and the APP or the short-range on the mobile terminal 2, namely after the target user uses the mobile terminal 2 for networking for obtaining the electronic key for the first time, the target user starts to calculate the time from the last offline of the APP or the short-range, the electronic key stored offline on the mobile terminal 2 defaults to the longest 2 days (the storage time can be prolonged by operating and proposing a request to change in the APP or the short-range on the mobile terminal 2 as required), and due automatic clearing is realized, so that the offline normal use of the electronic key by the mobile terminal 2 is ensured to pass, and the unlimited use of the electronic key is also prevented.
In the using process, the safety problem is considered, the two-dimensional code data generated by the APP or the applet on the mobile terminal 2 are changed in real time, the time (accurate to second) of the user mobile terminal 2 is obtained to participate in the encryption calculation of the data, the encrypted data generated every second are different, the variability of each encrypted data is guaranteed, and meanwhile, the passing operation is also carried out for preventing external illegal simulation data. The access control system reads the two-dimensional code data, and the encrypted data in the two-dimensional code is intercepted and compared with the data calculated by the access control system to determine whether to open the electronic lock 6 for releasing.
In the process of generating the two-dimensional code on the mobile terminal 2, the current time of the mobile terminal 2 is taken as the main time, 5 minutes are taken forward in the current time to make the two-dimensional code generation time, and 5 minutes are taken backward to make the two-dimensional code expiration time (for example, 12:00, 11:55 in the first 5 minutes, and 12:05 in the last 5 minutes); and the access control system compares the equipment number in the received correct two-dimensional code data with the number of the current equipment. In order to solve the problems that the reading rate is influenced and the reading data failure is increased due to overlong data of the two-dimensional code, the length of the data is made to be the shortest as possible under the condition of meeting the functional requirements through the combination of the case differentiation of 26 letters, the numbers from 0 to 9 and other special characters (!, @#, #, … …). For example: the door lock system reads whether the read data is complete or not according to the length, and judges the legality according to the verification of the encrypted data; when the two-dimensional code contains the number of the current equipment and the passage is allowed in the valid time (judged by the generation time and the expiration time in the two-dimensional code data), otherwise, the passage is not allowed; under the condition that all have the equipment authority of passing, support simultaneously that the entrance guard electronic lock 6 among a plurality of entrance guard equipment of same two-dimensional code opens the pass.
After the access control system reads the information of the IC card, encrypted data in the IC card are subjected to encryption verification, whether the current equipment number exists in the IC card data or not is judged after the verification is passed, and if the current equipment number exists in the IC card data, the access control electronic lock 6 is opened and can pass, otherwise, the access control electronic lock 6 is not opened and refuses to pass.
The access control system disclosed by the invention completely works offline, and does not interact with a server background, and the IC card records complete data encryption information, so that the safety of interactive data is effectively ensured, and the phenomenon that the external world simulates data passing operation in an illegal mode is avoided; carry out data interaction through the two-dimensional code, when guaranteeing that data satisfies the integrality of function, consider that access control system reads the two-dimensional code data and probably fail, lose the scheduling problem, can support multiple type two-dimensional code, for example: a common two-dimensional code, an administrator two-dimensional code, and the like. Under the conditions of offline of the door lock system and offline of the mobile terminal 2, the timeliness and usability of the two-dimensional code and the random password in the using process can be judged and processed, and the problem that normal passing is influenced due to possible time errors of the access control system and the mobile terminal 2 is solved.
