Design of "Campus Guards" System Based on Dual-frequency RFID
Liu Zhong-wu · The Internet of Things · 2011
The Campus Guards system is based on dual-frequency technology to realize the RFID card awakening and identification function. This system includes management sub-system, short message management sub-system and acquisition sub-system. The RFID card carried on by the pupil will be automatically (retained) in the dormant state, producing zero radiation, and it is helpful to ensure the health of the pupils. Only when the pupils approaching the school gate for entrance into the school campus, the RFID cards being carried by them will be activated and start sending pupils information to the reader installed at the gate location. Through RFID data acquisition and processing, the Campus Guards system will realize the technique security management. The introduction and application of the system will effectively improve the security management of the school.
