[0031] In a specific implementation method, when in use, for fixed in-and-out personnel such as students, teachers and other school staff who are convenient to enter the database, first collect their facial information and enter it into the database, and then collect the facial information in real time through the face recognition module when entering and exiting, and compare the facial information with the facial information in the storage module to obtain the result of whether the person exists in the database;

The power of the main radar detection module is normally off. When the main control module receives a signal from the auxiliary radar detection module that there is a moving human body, the main control module controls the power of the main radar detection module to power on, and then the main radar detection module enters the working state. It can convert external human body signals into electrical signals and input them to the main control module, so that the main control module records situations such as human bodies approaching or staying or intrusion within a specified range.

[0036] The face recognition module extracts facial features based on people, and then compares them with known facial features. The power of the face recognition module is normally off. When the main control module outputs the main radar detection module to record that a human body is approaching the set distance, the main control module controls the face recognition module to power on, and then the face recognition module enters the working state. It can convert the recognized facial features into electrical signals and input them to the main control module, so that the main control module records and determines whether the face has access permission, etc. After the main control module completes recording the input signal of the face recognition module, it turns off the power of the face recognition module, and then the circuit enters a low power consumption state;

[0037] Scanning module, the main control module wakes up the scanning module according to the detection signal of the face recognition module. The power of the scanning module is normally off. When the main control module outputs that the face recognition module determines that the face has access authority, the main control module controls the scanning module to power on, and then the scanning module enters the working state and performs metal detection on the detection area. The scanning module converts the detection result into an electrical signal and feeds it back to the main control module. The main control module integrates and records the operation process of the scanning module. When the face recognition module cannot detect the human body, it outputs a signal to the main control module, allowing the main control module to turn off the power of the scanning module, and then the circuit enters a low power consumption state;

[0038] The main control module outputs a driving signal to the access control driving module according to the detection signal of the scanning module, and the access control driving module controls the access control gate to open according to the control information;

[0039] A voice broadcast module, wherein the voice broadcast module is connected to the main control module by signal, and the main control module controls the voice broadcast module to broadcast corresponding voice based on the recognition information of the recognition module;

[0040] The sound and light alarm is installed on the access control gate. The main control module controls the opening and closing of the sound and light alarm based on the identification information of the identification module. The sound and light alarm used is a sound-controlled light. When criminals break into or enter the campus, a sound alarm and a light alarm are issued to deter criminals. The scanning module, through its metal detector, will make a sound when encountering metal to remind law enforcement personnel, so that criminals entering and leaving the place can be easily and quickly captured.

[0041] In summary, the utility model realizes the role of providing different types of identification methods for different types of personnel through the identification module and the scanning module. For fixed in-and-out personnel such as students and teachers, the face information database can be entered in advance, and then the identity can be identified and the gate can be opened through real-time collection and comparison. For non-fixed in-and-out personnel who are allowed to enter the campus during special time periods, such as takeaways or parents of students, they can enter the campus by swiping the card by obtaining the form of identification cards through personal information entry. Moreover, the identity information of such non-fixed in-and-out personnel will be uploaded to the management terminal for easy archiving and management. In addition, the camera set on the identification module is also connected to the management terminal through a wireless communication module or a network module, and the surveillance video acquisition of the whole day, all time periods or part of the time period can be realized through the camera, and the entry process of each person entering and leaving the campus can be further recorded, realizing the archiving and management of the surveillance video. The scanning module is used to prevent the entry of controlled knives into the campus. Through radar recognition, face recognition and metal scanning, illegal off-campus personnel and controlled knives can be checked while commuting normally, ensuring the safety and daily consumption of teachers and students in the school.
