　　RFID technology home-school communication system background service:

　　1) The background system sends the student's entry and exit information to the parents through the SMS modem or SMS platform operator, so that the parents can know the student's school status well.

　　2) The system administrator can record student information through the home-school management system network platform. Such as test scores, rankings, class information, etc. Parents can view student information through the online platform.

　　3) Parents, teachers and school administrators can communicate by logging in to the school's online platform. Parents can know the learning situation of their children in school in time.

　　The working principle of FID technical home-school communication system

　　The activator is installed in the guard room or the surrounding area, and two 125K coils are led out; they are the No. 1 activation antenna and the No. 2 activation antenna. When students with dual-frequency electronic tags enter the school gate, they are 1-3.5 meters away from the No. 1 activation antenna. When in the range, the low-frequency activator will emit electromagnetic waves and 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. The reader receives the radio frequency signal from the dual-frequency electronic tag and the IP of the activator and transmits it to the background through the 485 or TCP/IP interface; with the students When gradually entering the inside of the gate, the electromagnetic wave energy carried by the activator gradually weakens until the dual-frequency electronic tag can no longer be activated, and the B activator starts to activate the vehicle electronic tag. After the electronic tag is activated, the ID information of the electronic tag itself and the activator The IP is sent to the reader at a certain rate. The reader receives the radio frequency signal from the dual-frequency electronic tag and the IP of the activator and transmits it to the background through the 485 or TCP/IP interface. The background is based on the read sequence and difference of the low-frequency activator. The ID number of the activator antenna to make a judgment;
