Business overview
The School News Ping An SMS system is an information interaction platform commonly used in primary and secondary schools in China. This solution can ensure the safety of primary and secondary school students, increase the communication between teachers and parents, and promote the informatization construction of schools and education departments. However, the short-distance swipe card attendance method adopted in the traditional school news communication solution also highlights its shortcomings in actual use: the traffic of school gates during the school and the school gate increases sharply, and there is a phenomenon of long lines of students swiping card attendance, which is serious Affect the efficiency of swiping cards.
With the development of technology applications, we are now able to completely solve this problem. The 2.4G school news access barrier-free attendance program adopts the data interaction method of long-distance inductive card reading. Students only need to walk through the school gate to complete the attendance, without queuing in and out of the school as in the past. This solution also supports swiping a card on the school’s communication terminal to make a family call, which greatly saves the user’s investment cost.
Construction necessity
◆Campus safety needs
The campus is a paradise for the healthy growth of children, but now it is facing the threat and destruction of many social insecurity factors. The country attaches great importance to the safety of students’ campuses. The Ministry of Public Security and the Ministry of Education jointly convened an emergency video conference to strengthen the safety and security of schools and kindergartens, focusing on further strengthening the security of schools and kindergartens for re-mobilization and redeployment. State Councilor and Minister of Public Security Meng Jianzhu emphasized at the meeting that it is necessary to further implement the spirit of the instructions of the central leadership comrades, further implement the inspection and rectification measures for hidden safety hazards in schools and kindergartens, and further implement the security prevention and control measures around schools and kindergartens. , To further implement the safety responsibilities of schools and kindergartens, and effectively maintain the safety and stability of schools and kindergartens.
The prevention and control of campus safety accidents not only requires the participation of society, schools, and parents, but also effective technical means. The schoolpaper’s safe SMS system uses advanced methods such as radio frequency technology and wireless communication technology to ensure the safety of students entering and leaving the school. welcome.
◆Customer’s needs
At present, the school’s business is developing rapidly, and its business functions are recognized by the majority of elementary and middle school students, parents, schools, and education management departments. With the deepening of business, users’ application requirements for the system have gradually increased and become more diversified. In order to better meet user needs and enhance mobile’s brand awareness, it is urgent to improve the school’s business system.
1. The existing card-swiping method of attendance requires students to “actively” participate, and there will be the phenomenon of forgetting to swipe the card, and the accuracy of the data will be affected.
2. During the peak hours of attendance at school and after school, there may be queues for swiping cards due to excessive concentration of personnel, and the swiping efficiency is low.
3. Every time attendance requires a series of actions such as finding the card, swiping the card, and putting it back, which is not humane enough today when barrier-free technology is mature.
Technical solutions
◆Scheme overview
“Campus 2.4G Barrier-Free Time Attendance Solution” (hereinafter referred to as this solution) is a major performance improvement made by Guangdong Tianbo Information Technology Co., Ltd. on the basis of the existing school communication system. This solution uses advanced 2.4G UHF RFID signal interaction technology to realize long-distance non-contact personnel attendance. Significantly improve the attendance passability, and the operation is more user-friendly. This program represents the development direction of campus information management.
This program is mainly for school attendance information management. When a student (or teacher) wears a 2.4G active composite card to enter or leave the school through the school gate, the long-distance card reader will read the data of the student card and transmit it to the school’s school communication terminal through the RS485 cable. The communication terminal sends attendance records to the school communication platform through the mobile GSM/GPRS channel, and the platform sends safety short messages to the parents’ mobile phones. This program retains the original family phone function of the school paper communication system, and the 2.4G active composite card integrates the ID card function, and students can directly swipe the card on the terminal to make a phone call.
◆Scheme features
1. Long-distance recognition: Using 2.4G RFID long-distance sensing technology, people do not need to actively swipe their cards when they pass, as long as the card is hung in front of the chest or in the schoolbag, and they can be identified directly after passing.
2. Humanized fast channel: People don’t need to stay and wait, they can pass directly. It can identify >100 cards at the same time, and the distance can be up to 80 meters.
3. High recognition rate: The recognition rate is within 80 km/h, the recognition rate can reach 100%, and the bit error rate is one in ten million, which can meet the high recognition rate requirements.
4. Real-time data reporting: Attendance records are reported to the platform in real-time via the School News Terminal, which is convenient for query management.
