Smart Campus WeChat Electronic Code Gate Push System - Face Recognition Solution "Innovation Technology"

Children are the future of the motherland and the hope of their parents. Children's safety is a very important part of the entire social security work. It is directly related to whether children can grow up safely and healthily, and it is related to the happiness of thousands of families and social stability. Campus safety has become a hot issue of concern to all sectors of society. Protecting every child and reducing accidents to a minimum has become an important part of education management in kindergartens, primary and secondary schools.

2. System Overview.

The Smart Campus WeChat Push System is launched to address campus safety issues in my country, and is mainly designed for kindergartens, primary and secondary schools. It relies on new AI technology, combines face recognition with Internet technology, and works with school staff and parents to efficiently supervise the safety of students entering and leaving the school.

The entrance and exit of the school gate is a line of defense for security protection. Effective supervision and recording of people entering and leaving the school gate is the key to implementing safety precautions. Face recognition uses advanced deep learning algorithms to effectively judge students and non-school personnel and prevent non-school personnel from entering the school. Information push adopts the deployment mode of WeChat WeChat official account. Parents do not need to install APP on their mobile phones. They only need to pay attention to the identity information of their children bound to the school's WeChat official account to receive the time when their children enter and leave the school and the photos taken on site.

The third is the highlight of the WeChat push system.

★ Cost-effective: Parents use the audience WeChat application to receive information, and can send text, pictures and other multimedia information for free. WeChat is completely free and can receive information in real time.

★ School WeChat WeChat official account push: Pushing student entry and exit records and photos is completed by the school's own WeChat WeChat official account, not in the name of a third-party platform. Parents only need to pay attention to the school's WeChat WeChat official account, and they can easily scan the code to bind their children's identity information. The WeChat official account can show the style of the school and is managed by the school independently. Unlike some third-party platforms, it will push business information from time to time, affecting the parent experience.

★ In-body detection: In-body detection prevents criminals from using mobile phones, photos, etc. Cheating endangers student safety.

★ Simple operation: The WeChat push system adds the WeChat WeChat official account push function on the basis of face recognition access control. The school only needs to register student information, and parents only need to scan the code to follow and bind their children's identity information. The operation is simple and suitable for all ages.

★ All-round push information: The information received by parents includes name, time, school entry and exit status, on-site snapshots, etc., so that parents can grasp the information at one time.

★ Efficient face recognition: The face recognition terminal uses Huawei HiSilicon industrial AI chips, embedded systems, and high-definition wide dynamic AI camera lenses. It can show superior performance in strong light, backlight, indoors and outdoors, allowing students to pass efficiently and orderly. It also supports card swiping and is compatible with ID cards and IC cards.

★ Time-limited function: The system can set multiple time periods, and different access permissions for students and faculty can be set according to students and faculty to prevent students from leaving school privately during class.

★ Stranger alarm function: After the face device detects a stranger, it will issue a stranger language alarm to remind the security guard.

★ Voice broadcast function: After identifying the student, broadcast the student's name, and the voice can be customized.

★ Large screen statistics function: The TV can expand to display the actual student data of each class.

★ Ultra-large capacity: The face recognition terminal supports 20,000 students.

★Batch import function: supports batch import of student face database photos, which greatly improves work efficiency.

Fourth, the working mode of the WeChat push system.

School side

1. The school is responsible for providing the school's WeChat official account. The WeChat official account must be a service account and must be certified by the official WeChat. Uncertified WeChat official accounts cannot open the push interface.

2. Register student information into the system, and the system will assign a QR code to each student. The QR code can be generated in batches according to the class and distributed to the corresponding parents by the teacher. Each QR code can only be bound once and will become invalid after binding.

3. Delete the permissions of transfer or graduation students.

Parent group

Use the WeChat that needs to receive the child's entry and exit push information, follow the school's WeChat official account, and scan the QR code provided by the teacher to bind. When the child enters and exits, he can receive push messages in time, and contact the school in time if abnormalities are found.

Student group

Face recognition in and out of the campus gate. When entering and leaving the campus, the camera will take pictures of the scene. This information will be pushed to the parents' WeChat through the server, and the data will be stored on the school server.

Verb (abbreviation of verb) Face collection

Requirements for face photos.

You can import face pictures pre-stored on the computer into the camera as a template library for the camera to compare faces. These photos can be taken with a mobile phone or a camera. In addition, you can use a USB camera to take face portraits on the spot. The pictures uploaded to the face database must have only one face. Below:

Note: When registering a portrait, the following situations should be avoided to avoid multiple registrations and comparison success!

Sixth, the advantages of face recognition

Non-mandatory features: The recognized face image information can be actively obtained without being detected by the individual being tested. Face recognition uses visible light to obtain face image information, but unlike fingerprint recognition or iris recognition, it requires the use of electronic pressure sensors to collect fingerprints, or infrared to collect iris images. These special collection methods are easily detected by people and are therefore deceptive.

Intuitive: Face recognition technology is based on human facial images, and the face is undoubtedly an intuitive information source that can be distinguished by the naked eye. "Judging people by appearance" conforms to the cognitive laws of human beings. At the same time, it is convenient for later manual confirmation and has obvious advantages such as reuse.

Natural advantage: The so-called naturalness means that this recognition method is the same as the biological characteristics used by humans in individual identification, that is, to distinguish and confirm identities by observing and comparing faces; the natural recognition in the system includes voice recognition and body recognition, while fingerprint recognition and iris recognition are not natural, because humans cannot distinguish individuals through such biological characteristics.

Non-contact advantage: Compared with other biometric technologies, face recognition is non-contact, and users do not need to directly contact the device. At the same time, it can meet the needs of sorting, judging and identifying multiple faces in actual application scenarios.

Not easy to forge: Face recognition technology requires that the object to be identified must be personally at the recognition site, and others cannot forge it. The unique active recognition ability of face recognition technology ensures that others cannot deceive the recognition system with inactive photos, puppets, wax figures or even avatars.

VII. Composition of face recognition WeChat push system

The WeChat push system is designed based on the campus security needs by combining AI technology with the Internet on the basis of the conventional face recognition access control system. It is easy to install, simple to deploy and flexible to operate.
