I. Demand Analysis

It has been long headache in many elementary schools and middle schools all

over the world. Every morning, kids go to school and parents go to work. What

if kids dont get into school safely? What if they play truant? How can parents

know? If there is a system that can inform parents whenever their kids arrive or

leave school, then the problem is solved. Fortunately, our student

arriving/leaving safely message service system is designed for such purpose

and much more.

We all know, basically both school and parents want to know:

Safety: whether or not arrive and leave school safely

Attendance check: whether or not arrive and leave school on time, be late

or leave early

Behavior in school and at home: grades, attitude, etc.

Moreover, how to build channels for school and parents to make

communications simpler, more efficient and more effectively? How to let

parents get chance to know more about their kids in school? How to let

teachers know about kids behavior at home? All these problems have been

noticed for long time and people has found many ways to try to solve these

problems from different angles.

superRFIDs student arriving/leaving safely message service system combines

advanced RFID technology and widely used cell phone message service

provided by telecom companies, to build a powerful and convenient tool for

school and parents.

II. System brief description and designfundamentals

1System function1.1 Send message to inform parents their kids have safely arrived or left

school

Arriving: each student wears a tag with unique ID . When he enter the gate,

reader nearby detect tag ID immediately and upload information to system to

inform his parents

Leaving: When student leave school, the reader nearby detect tag ID

immediately and upload information to system to inform his parents

1.2. Student attendance checking

Students dont have to stop to slide card one by one and the system

automatically record all attendance information.

1.3. through message system, teachers and parents can communicate

conveniently

School notice: teachers can inform them parent meeting, payment, etc.

Student status notification: teachers send evaluation of students, such as

behavior in class, homework, behavior comments, exam grades, recent statusto parents

Notes from parents: parents send message to teachers in charge of class or

school principals

1.4 . assistant mobile office

Meeting notice: send message to teachers through message inside school

Personal reminding: customize personal time message to remind in time

2System scenario Realize message transmission and receiving through message CAT or

gateway of mobile communication service provider

Reader is installed near the gate and connected to server. Students

wearing tags will be detected automatically when passing school gates,

and message will be sent accordingly

If campus LAN is available in the school, then server can be connected to

it. Staff can log on to system software through IE to communicate withparents by sending messages

2. System Hardware

2.1 Summarization

Long reading range tags are issued to students and reader is installed above

the school gate. When students wearing tags pass the gate, reader will detect

those tags automatically and send there IDs to server, and finally send

message to their parents. There is no need for student to stop to slide cards as

usual and reader can detect multiple tags at the same time, so students do not

have to pass the gate one by one.

2.3 brief description

Each student wears a wireless tag. When they pass school gate, the reader

nearby will detect those tags, judge his direction (coming in or going out), then

send information to computer. The computer will send corresponding message

to parents. For example, Daddy, I am in school now or Daddy, school is over

and I will be home in one minute. The same information is also backed up in

computer and made into report forms for future reference. On the other hand,

we can store students personal information in tags, such as blood type,

emergency phone number, in case needed. Such system is very popular in

North America and Europe, useful and convenient. Our systems have been

successfully put into use in many schools in Inner Mongolia, Chengdu,

Xinjiang and worked stably for a couple of years. Such system can also find

applications in prison management and customers feedbacks proved our

success.

Compared with other companies, our products have some outstanding

features: with longer identification range, students can pass the gate without

having to stop to slide cards on machines. Therefore, it is much more efficient

when many students try to pass the gate at almost the same time. Moreover,even if many students pass the gate simultaneously (up to 200) or the card is

blocked by another student or his own body, the tag can still be detected

accurately and timely, no chance of miss reading. Besides, with ultra low

power consumption, one single card will be enough for each student from first

enrollment to graduation, no need to change battery during the whole school.

2.4 System features

long reading range: tags can be detected within 50 meter range. There is

no need to slide cards or get into a small required area to make sure tag is

detected. All processing is automatic. As long as students wear tags, they

can pass the school gate freely without any extra operation. We can see

benefits clearly at rush hours.

Anti-collision: up to 200 students can be detected simultaneously, walking

in or on school bus.

Support identification of fast moving objects with speed up to 200

kilometers

V. Case Study

1. summarization

A typical school is composed of two gates, two teaching buildings and an office

building. Central computer control room is in office building. Mail room is

besides gate 1, while there is a parking lot besides gate no. 2. the simple

diagram is as follows:

In this case, long reading range solution is chosen. Therefore, all processes

are automatic. As long as students wear tags as required, they do not have toslide cards to enter school gates.

System network is as follows:



Page 19 of 25


20/25

SUPER-RFID

At gate 1, reader is installed on the wall (under ceiling) and power is provided

from mail room. At gate 2, reader is installed on the top of the external wall ofparking lot and power is provided from parking lot.

Reader is connected with switching machine through RS485 IP converter

to realize IP packaging and transmission. Each reader need to be equipped

with one converter and between reader and converter, RS485 cable is applied.

Notice the cable must be covered with PVC casing. Network wire is used

between converter and switching machine.

Optical cable laid by telecom service providers enter into central computercontrol room and is connected to system server. Data communication

between control room and No. 1, No. 2 office buildings are fulfilled by campus

network.

Once system hardware installation and software deployment are finished, we

need to do system function and performance testing, including signal coverage

testing, interface testing, data transmission flow testing and converter data

flow testing.
