It should be noted that, in the actual application process, the allowed entering personnel may need to enter and exit the passage many times in the state of task execution, and if the allowed entering personnel needs to pass the verification each time, the working efficiency will be low, therefore, the entrance guard passing instruction is sent to the identity database 103 for storage, when the allowed entering personnel is in the state of task execution, the entering passage can be passed only after the identity verification is successful, and if the task execution time is expired, the state is interrupted or suspended in the task execution, the corresponding entrance guard passing instruction needs to be deleted, so that the entering personnel can be subjected to identity verification and pass verification again.
Further, the system further comprises a qualification auditing module, wherein the qualification auditing module is used for performing qualification auditing on the successfully matched to-be-identified identity information based on the qualification information prestored in the identity database 103, and is also used for judging whether the access permission instruction is valid according to a qualification auditing result, if the qualification auditing result is that the auditing is passed, the access permission instruction is valid, and if the qualification auditing result is that the auditing is not passed, the access permission instruction is invalid.
It should be noted that after the identification information to be identified is identified and successfully matched, qualification audit can be performed on the identification information, items of the qualification audit can include job qualification, historical violation information and risk rating, a qualification audit score result is obtained by scoring each item of the qualification audit, if the qualification audit score is higher than a predetermined score, qualification audit is passed, if the qualification audit score is lower than the predetermined score, qualification audit is not passed, entry of a station entering person into a channel cannot be passed, and an access permission instruction is invalid.
Further, the identity recognition sub-module 102 is further configured to generate an identity audit instruction and send the identity audit instruction to the instruction sending module 300 when matching of the identity information to be recognized fails, where the identity audit instruction includes the identity information to be recognized, which is failed to match;
