The hardware includes the transmitting antenna, receiving antenna, antenna tuners,acquisition and long-range radio frequency card; the software includes application software and embedded firmware. They achieve the functions of information collection,storage, identification analysis,data transfer and information dissemination.

 

Features of Solution

1、 Low Power Consumption and Dual-mode Active RFID Card When the “Campus Card”through thelow frequency antenna coverage zone, it will trigger the RFID card high-frequency circuits and initiative launch high-frequency carrier signal encryption (which has target ID) to acquisition instrument. Though this system, it can make sure RFID card in lowpower mode in most of the time.

2、Barrier-free Open-channel Model “Campus Security Guards” management system changes the traditional swiping Card management system. When students equipped with the "Campus Card", they don't need to swipe their cards.

The wireless system uses channel isolation technology. Multiple devicescan work without disturbing each other. The system operate safe, stable, and reliable. The front-end have high recognition rate, and the error rate has minimum bit. The wireless system has information anti-collision function. The communication mode”RS485” can identify 100RFcard in the same time. 

 

Application Cases

Datang Telecom participate in the construction of Internet of things application projects----Xi'an Branch of China Telecom "Campus Guards" project has been accepted successfully, which is the first large-scale campus Internet of things. The project includesthe construction of "Campus Guards" system in 136 primary and secondary schools. It is the first large-scale RFID technology campus application demonstration projects. The project has RFID collection and Identification equipment,distributed server, integrated service platformand other projects.

When students get in or out of school with their  "Campus Guards" card, two loggers will read the information of RFID card. Through telecomplatform, computer sends SMS to their parents. Their parents can use integrated platform read the information about homework, exam results, notices, children’s performance, and so on.
