　　Introduction of RFID technology home-school communication system

　　1. System introduction

　　The home-school communication security short-message system is a world-leading comprehensive information management system developed by using high-tech long-distance radio frequency identification (RFID) technology, mobile phone short message service platform and computer information processing technology. Parents provide an information service platform.

　　Using long-distance RFID technology and low-frequency activation technology, the low-frequency activator of readers is installed at the school gate, and students will be activated to read when they carry tags in and out. The tags are usually in a dormant state to save power and increase the life of the tags. The reader uploads the tag ID and the activation antenna ID to the system server via RJ45, WIFI or GPRS, and the home-school communication system can determine specific information (such as: personnel name, location, time of appearance, etc.) after processing, and send students The information of entering and leaving school is sent to the parents of students through short messages, so as to provide effective management methods for parents to keep abreast of student trends and school conditions. The system server can also sort out various attendance reports during this time period (such as late/early leaving records, non-attendance time, etc.) according to the information of personnel entering and exiting the school gate during the period of school and end of school.

　　Student Card: Use a semi-active tag as a student card. The tag is usually in a dormant state. When it enters the activation area, it will automatically send the tag ID and the activation antenna ID number every 200ms (parameters can be set). After leaving the activation area, the tag will automatically sleep;

　　Reader installation: Install two directional readers at the school gate, one reader is installed outside the school, and the other reader is installed inside the school. Through the identification tag ID and the corresponding activation antenna ID, the student’s status can be effectively judged. In and out state.

　　Activator installation: Install a 125K low-frequency activator (with two different ID125K coils) at the school gate, one antenna inside and outside the school gate, working synchronously.

　　Data transmission: The reader will transmit the recognized student card information to the school's server via RJ45, GPRS or WIFI, and the system can judge the student's entry and exit status based on the returned information.
