1. System Significance
Home-school security SMS system is the requirement of the whole teaching industry’s safety work. It can provide parents with accurate information about their children’s arrival and departure from school and school. At the same time, it is also a scientific campus management method, which can improve campus safety and security. The modern management level of the campus.
1) For schools: Informatization of attendance management and informatization of student management.
2) For students’ parents: real-time and convenient access to students’ entry and exit information.
3) For students: Family phone, students can establish free phone communication with their parents through the communication platform.
Carry electronic resume, credit payment for consumption, students can use electronic student ID card at the designated consumption field of the school
consumption within the premises.
2. Explanation of system architecture and scheme
The Home-School Link Ping An SMS System is a semi-active system adopted by Shanghai Renwei Electronic Technology Co., Ltd.RFIDTechnology, to monitor the card reading of personnel entering and leaving the campus, realizes the need to queue up to swipe the card for attendance, and can accurately know the students’ arrival and departure time to supervise and manage the safety of students. At the same time, parents are notified in combination with SMS platforms, so that they can obtain the status of students, and can respond to some special occasions. It is a good solution to the management of automatic entry and exit judgment of students in school, student attendance management, and safe SMS management. It greatly improves the safety and management efficiency of students in school, improves management efficiency, and reduces the work intensity of managers. At the same time, the system has an open interface and has various expansion functions, such as linkage with video surveillance system to achieve refined management.

2.2 Explanation of the plan
Installation location
The activator is installed in the guard room or around, and leads out two 125K coils; the No. 1 activation antenna and the No. 2 activation antenna respectively. When students with dual-band electronic tags enter the school gate, the distance from the No. 1 activation antenna is 1-3.5 meters. When the range is reached, the low-frequency activator will emit electromagnetic waves, which will be received by the dual-frequency electronic tag. The dual-frequency electronic tag receives the energy carried by the electromagnetic wave and activates the 2.4G active electronic tag. After the active electronic tag is activated, the electronic The ID information of the tag itself and the ID of the activator are sent to the reader at a certain rate,ReaderReceive the radio frequency signal and the IP of the activator from the dual-frequency electronic tag and transmit it to the background through the 485 or TCP/IP interface; as the students gradually enter the inside of the gate, the electromagnetic wave energy carried by the activator gradually weakens until it can no longer activate the dual-frequency signal. The B activator starts to activate the electronic tag. After the electronic tag is activated, the ID information of the electronic tag and the IP of the activator are sent to the reader at a certain rate, and the reader receives the radio frequency signal from the dual-frequency electronic tag. And the IP of the activator and passed to the background through the 485 or TCP/IP interface, the background makes judgments according to the sequence of reading the low-frequency activator and the ID numbers of different activator antennas;
