1. System background and implementation significance
1.1, the background of the system
In recent years, many off-campus crime incidents have occurred in our country’s schools, especially in recent months. Criminal cases are extremely frequent. How to strengthen the safety management of students and the personal safety of students at school? How can parents and school teachers be effective in dealing with the situation of students at school from time to time The mastery has been placed in front of the parents of each student, school leaders, and leaders of competent departments at all levels. Such problems involve the future of the country, the vital interests of schools and students, and the establishment of a harmonious society to maintain stability and unity. Therefore, we should do everything possible to solve these problems. However, due to the large number of students in the school and the high mobility within the school, it is difficult for ordinary teachers to grasp the situation of each student’s visit to the school in a timely manner. Parents cannot know in time whether their children go to school and leave school on time. Once a child skips class and does not go to school or after arriving at school, the teacher and parents are unable to understand the specific situation in real time, which will bring great difficulties to the management of the students and the education of the children. It can be seen from this that the school Xuntong management system is a requirement for the safety of the entire teaching industry. It can provide parents with accurate information about their children’s arrival and leaving school. At the same time, it is also a scientific campus management method that can improve the campus. Safety guarantee and modern management level of the campus.
The issue of school safety is currently an issue of widespread concern to the whole society. Due to the lack of effective communication between the school and the parents, a “vacuum zone” has also appeared in the growth and education process of young people. It is precisely because of this that many elementary and middle school students are exposed to some bad phenomena in the society prematurely, which has a bad influence on their growth. Frequent school violence incidents are the most direct manifestation. It is urgent to establish an effective communication platform between schools and parents, to curb the occurrence of school violence, and to create a good environment for the growth and education of young people.
For the growth and education of primary and middle school students, teachers need to communicate with parents in a timely manner. Whether the child arrives (leaves) the school on time, and how the school life is like, is the information parents need to know accurately. The school Xuntong system mainly uses the universal application of mobile phones and text messages in the masses and the characteristics of mobile phone text messages to establish a communication platform for parents and schools. Its core concept is “advanced technology, mature application, to solve the most concerned problems of schools and parents.” With School Express, as long as parents have a mobile phone, they can receive text messages sent by the school, realizing real-time communication between the school and the parents.
1.2. Implementation significance
In the early stage of the promotion of the “Xiao Xun Tong” business, students may be out of curiosity or under pressure from the school to swipe the non-contact RF ID/IC card on the “Xun Xun Tong” terminal every day, so that students can go to school or leave school. SMS attendance.
With the passage of time, the enthusiasm of students taking the initiative to swipe the card on the “School Xuntong” terminal will gradually diminish, and the number of students who evade or refuse to swipe the card will gradually increase.
At this time, as an operator, you may face the following problems…
1) The monthly amount of card swiping for the “School Xuntong” business is gradually decreasing?
2) How to expand the monthly tasks of the “School Xuntong” business?
3) Can the monthly KPI assessment complete the indicators?
4) How to effectively solve the attendance problem of students going to/from school?
Just imagine: In a relatively long period of time, if parents’ mobile phones do not receive or rarely receive students’ attendance information, do you think that parents will pay for the “School News” business for a long time?
In order to relieve your troubles, please choose 2.4G-RFIDThe overall solution for long-distance credit card attendance!

2.2. System network architecture diagram
2.3. The working principle of the system
1) 2.4G radio frequency card carried by students: The working mode of this card is active, powered by the battery inside, and the battery life is 2-3 years. Active identification cards continuously actively send out radio signals (3 times per second, the transmission power can be modified according to user requirements), and can transmit a long distance, the wireless signal is coded, each identification card The code is unique.
2) Entrance and exit card readers, according to the school regulations, install one or two card readers at each door.
3) When a card reader is installed at each door of the school, there is no need to install a directional antenna, and the entrance and exit of students can be judged by time (the school stipulates that a certain period of time is the school time, a certain period of time is the school time, and the normal time is not allowed. In and out).
4) When a two-year card reader is installed at each door of the school, one is installed inside the school door and the other is installed outside the school door. A directional antenna must be installed for each reader to shield the other half. signal of. Judge whether to enter the school or leave the school by reading the sequence of the 2.4G card. For example, if it is read by the card reader installed outside the school gate and then read by the card reader inside the school gate, it means that you have entered the school; otherwise, the opposite is true.
5) The card reader transmits the information of reading the tag to the school’s server (computer with network) through the interface line, and judges the information to be transmitted based on the time coming or going in and out.
6) The school xuntong server stores the basic information of students. This server can be prevented by the school xuntong platform and SMS platform. And can communicate with each other. The server transmits the student information to the SMS platform.
7) SMS platform, through this platform, you can send text messages to parents. Let parents know the situation of students in school well.
8) The system administrator can use the school Xuntong management system to go online to modify the student’s information. Such as test results, rankings, class information, etc.
9) School Xuntong management system. School Xuntong management system can record school and student information. Parents, teachers, and school administrators log on to the school news platform to communicate. Know your child’s learning situation at school from time to time.
2.4, actual case
The school Xuntong management system first installs several card readers in the school’s intersections, main passages, and key monitoring sensitive areas. The specific number and installation location are determined according to the actual working conditions on site and the functional requirements to be achieved. Connect with the computer in the control center through wiring or wired/wireless network. At the same time, distribute an electronic tag to each school personnel and visitors who enter the school temporarily. When the person wearing the personnel card is in each area of the school, he/she only needs to pass through or approach any card reader placed in each area to read The card reader will immediately sense and upload the corresponding electronic tag number, reader’s own number and time to the computer in the monitoring center. The historical status and time) of a specific person to determine the current status (location, whether in the school, stay time in the school, stay time in a specific area), statistical information of the entire school and a specific area (number of people online ) And trigger events (for example, someone enters or leaves the school, someone stays in the school for overtime, someone does not follow a pre-designated route, someone goes to an area that shouldn’t go), and displays this information at the same time Display the screen on the computer and back it up to the database. The administrator can click on a certain location in the school or select the entire area according to the distribution diagram on the computer display screen, and the computer will sort and display the information of all personnel in this area. The administrator can also select a time period (a certain day or a certain few days) and a report type (attendance report, warning report for entering and exiting a certain area), recording report, personnel history tracking report, and violating the predetermined security policy. Get the required report. In addition, once an accident occurs in the school, the personnel at the accident site can be found immediately based on the personnel distribution information in the computer. The processing of temporary visitors is basically the same as that of permanent personnel, except that additional information is added to cancel and re-authorize the electronic tags.
