1. Program overview
The school’s RFID remote attendance system is a technology that combines RFID cards and smart attendance. This system changes the traditional management mode of swiping cards in the past. When students wear student cards to enter and exit the school, they do not need to perform any operations (no need to actively swipe cards, No need to stop, you can even sit in the school bus and directly enter the gate of the school) The system will automatically recognize the student card information, automatically recognize whether you are arriving or leaving school, and automatically send a text message/WeChat app to the parents of the students to notify the parents that the children are safe Arriving or leaving school.
2. Solution advantages
1) Long-distance recognition, barrier-free, no need to queue.Students get in and out quickly, avoid gathering at the school gate, eliminate safety hazards, and reduce school management burden
2) Real-time notifications via SMS/WeChat app for leaving school, parents and schools can keep track of students’ entering and exiting dynamics in time to meet the supervision needs of their children.
3) One card for multiple purposes; in addition to RFID remote attendance and dormitory management, RFID student cards can also be applied to campus all-in-one cards to realize campus access control, dining hall consumption, library borrowing and returning books, school bus rides and other functions. It can also be used as an electronic student card to realize bus rides, etc.;
4) Do not change the original communication method; if the school’s original short-distance swiping platform, there is no need to change the original system, just connect to 2.4G long-distance products directly
3. Product advantages
Strong card endurance: Most student cards on the market use button batteries. Due to the characteristics of button batteries, the consistency of the power supply of student cards is not good, and the service life is only 1-2 years. Our student card uses a soft pack battery, and the card has a lifespan of 5 years.The company provides a 2-year warranty
Product adaptability: In daily life, the application environment of the school is simple and complex, and it is necessary to test the ability of product manufacturers as accurately as possible.Our products use a unique algorithm to make judgments and identifications more accurate and stable during actual use, greatly improving the use of the school environment. Comprehensive product series: due to the different school environments, the school environment is harsh and complex In the case of

6. Application scenarios and solutions
Due to the complex application environment of the gates of various schools and the different behaviors of students, it is difficult to achieve precise coverage area control with 2.4G RFID signals. 2.4G single-frequency technology cannot meet the application conditions of all schools. For situations where the school gate environment is more complicated or where dormitory attendance needs need to be taken into account, it is recommended to adopt a 3-band product solution.
6.1. Dual frequency solution
For schools with a long distance between the teaching building and the school gate, a dual-frequency scheme can be adopted. The dual-frequency solution product consists of a communication gateway, a long-distance card reader, and an electronic tag, and cooperates with the operator or channel provider’s own platform to realize value-added service applications such as SMS/WeChat app;
6.1.1. System framework diagram
School News Communication Platform Server
1) Students bring long-distance student cards in and out of the school;
2) According to different school regulations, install two card readers at each school gate, one is installed inside the school gate, and the other is installed outside the school gate.
3) When a student enters and exits the school, the reader automatically recognizes the student card information, and then transmits the collected student card information to the communication gateway. The communication gateway encrypts the data and sends the result of the in and out judgment to the school or school. School Card Platform
4) The school news communication platform sends the attendance report SMS/WeChat app to the parents.
6.2. Three-band scheme
For complex school environments (such as the school building is very close to the school gate, there is a turnaround road at the school gate, etc.), or the school needs to take into account the needs of dormitory management, it is recommended to adopt a three-frequency RFID product solution. The main products of this program are composed of communication gateways, long-distance readers, low-frequency calibrators and electronic tags.
6.2.1. System Framework
1) According to the school scale and management accuracy requirements, install a certain number of scalers inside and outside the school gate to form the coverage area of the school gate identification label.
2) At the same time, install a reader inside and outside the school gate
3) Students bring their student cards in and out of the school gate
4) When a student enters the coverage area outside the school gate, the calibrator starts to trigger the card, and stores the calibrator ID, time and other information on the card. The reader will read the calibrator and student ID, etc. The information is sent to the communication gateway
5) The communication gateway performs calculation and judgment on the relevant data, and sends the judgment result and other information to the school paper or school card platform
6) The school news platform sends safe SMS/WeChat app to parents
6.2.2. Advantages of the three-band solution
1) 100% accurate identification and access judgment, suitable for any school environment.
2) According to the requirements of school management, it can be expanded to realize comprehensive campus personnel positioning and dormitory management functions, accurate and fast
3) Reduce maintenance costs
7. Dormitory Management
Dormitory management is implemented with a three-frequency solution. A low-frequency scaler (underground lamp or wall-mounted type can be used), readers and communication gateways are deployed at the door of the dormitory to realize automatic attendance of students in and out of the dormitory.
The application icons are as follows:
8. Long-distance RFID parking lot management
In order to facilitate school attendance management of faculty and staff, and strengthen campus traffic safety management, a long-distance RFID parking lot barrier system is implemented based on our company’s 3-frequency product solution. On the basis of retaining the functions of the traditional parking lot, the system focuses on realizing the automatic identification management of vehicles, improving the efficiency and safety of vehicles, and enhancing the user experience.
8.1. System Features
1) The reading rate is high, and there is no special requirement for the card placement, and it can be placed at any position on the bridge or on the person.
2) Not affected by weather. It can be read under strong light or rain and snow.
3) Solve the problem of following the car before and after. There is no card in the front car, and there is a card in the rear car, so the brakes will not be misread.
4) Solve the problem of adjacent channel interference. For multiple entry and multiple exit lanes, there will be no misunderstanding and misjudgment.
5) The construction and debugging are very simple, install and use, and one-key configuration.
6) The electronic label card has ultra-low power consumption, uses a large-capacity battery, is maintenance-free, and has a service life of more than 5 years.
