Description: 近年来，随着计算机技术的发展和互联网时代的到来，我们已经进入了信息时代，也有人称为数字化时代，在这数字化的时代里，学校的教学管理都受到了极大的挑战。Internet技术持续迅猛的发展，也给传统的办学提出了新的模式。通过设计和建设网络拓扑架构、网络安全系统、数据库基础结构、信息共享与管理、信息的发布与管理，从而方便管理者、老师和学生间信息发布、信息交流和信息共享。以现代计算技术、网络技术为基础的数字化教学主要是朝着信息化、网络化、现代化的目标迈进。作为新型的办学模式，它们具有对于教育、教学过程来说极为宝贵的特性，可以为新型办学模式的建构提供理想的环境。在此开发的大学信息学院管理信息系统，旨在探索一种以互联网为基础的办学模式。通过这种新的模式，为信息学院营造一种新的办学环境，使管理突破时空限制，扩大教学规模，提高工作效率和办学水平，使学校管理者、教师和学生可以在任何时候、任何地点通过网络进行学习与交流。-In recent years, with development of computer technology and the advent of the Internet era, We have entered the information age, it was also known as the digital era, and in this digital era, schools have been teaching management a great challenge. Internet technologies continue rapid development, but also to the traditional school of new models. Through the design and construction of network topology architecture, network security system, database infrastructure, information sharing and management, information publishing and management, thus facilitating administrators, teachers and students between the release of information, exchange of information and sharing of information. With modern technology, network technology based on the Digital Teaching is mainly towards information technolo

Description: Radio Frequency Identification [RFID]
systems have become popular for
automated identification and supply chain
applications. This article describes the
technical fundamentals of RFID systems
and the associated standards. Specifically,
we address the security and privacy aspects
of this relatively new and heterogeneous
radio technology. We discuss the related
security requirements, the threats and the
implemented mechanisms. Then the current
security and privacy proposals and their
enhancements are presented. Finally we
discuss the role of this technology in
Ubiquitous Computing-The automated identification of objects
with electromagnetic fields is the major
purpose of the RFID [Radio Frequency
Identification] technology. An RFID system
basically consists of transponders [tags],
readers [scanners] and application systems
for further processing of the acquired data.
There is a large variety of different RFID
systems: they may use low, high or ultra
high frequencies, the transponder may emit
only a fixed identifier or possess
significant memory and processing
capabilities. Transponders may incorporate
no security features at all or realise
effective security protocols similar to
smartcards. Most transponders are
passively powered by the radio field
emitted by the reader but there are also
active tags with a separate power supply.
The transponder design is also little
uniform: there are e.g. tiny tags with a size
of several millimetres, very thin “smart
labels” or standard ID-1 cards

Description: Hello guys,
I ve built this GSM security system as my semester project using T290i mobile and controlled my car using it. Please leave your comments about it.
If any one needs help in implementing such a system, I can help.
Some of the functions it can perform are:
* start and stop the engine (without using the key)
* stop the engine if somebody starts it with a key ( by cutting off ignition)
* lock and unlock the doors
* send a text message to the owner if an intruder is detected (by monitoring the doors)
* switch the heater/air conditioner on and off

Description: This project aimed to develop a wireless system to detect and allow only the authorized persons. The system was based on Radio Frequency Identification (RFID) technology and consists of a passive RFID tag. The passive micro transponder tag collects power from the 125 KHz magnetic field generated by the base station, gathers information about the Tag ID and sends this information to the base station. The base station receives, decodes and checks the information available in its Database and Manchester code was used to send those information. The system performed as desired with a 10cm diameter antenna attached to the transponder. The Base Station is built by using the Popular 8051 family Microcontroller. It gets the tag ID and if the tag ID is stored in its memory then the microcontroller will allow the person inside.
RFID Reader Module, are also called as interrogators.

Description: 基于AT89S52的GSM安防系统
本人最近弄了个基于AT89S52的GSM安防系统，想到当初由一个新手开始做这个的时候在找案例参考基本都看不懂。所以我做好这个项目后，就把它无私贡献给大家。希望对有兴趣的朋友有所帮助。这是一整套的成品，里面有说明文档，99SE的原理图和PCB，还有全套代码。在这里需要说明一点的是，由于本人孤军做此项目，所以很多地方都不是很完善。
该程序已经实现发生警报，然后通过GSM发送短信到目标号码，然后由目标再回发相应的控制短信去控制。
更多请查看附件里面的说明文档-AT89S52 based on the GSM security system
I recently broke a AT89S52 of GSM based security systems, originally thought of starting from a novice to do this when looking for the basic reference case are read. So I do this project, put it selflessly to the party. Want to help friends who are interested. This is a set of finished product, which has documentation, 99SE schematic and PCB, have a complete code. Need to point out here is that, because I alone in doing this project, many places are not quite perfect.
The program has been achieved alarm occurred, and then send text messages to the destination GSM number, and then issued by the goal of returning to the corresponding control messages to control.

Description: The TMS Security System facilitates the definition of user rights on a menu or form level. In its user management features the TMS Security System relies on user/group profiles stored in a database.
The users can be grouped and can inherit rights in this way. Thereby you can integrate a highly sophisticated and close grained user management that closes all potential loopholes via shortcuts with minimal effort. Only if the user has been granted the specific right by the administrator he can see or use the specific function assigned by the administrator.
The administrator can configure the rights at run-time thereby preventing a restart of the program when changing assignments. For doing so he can use an easy to handle, intuitive GUI that enables the administrator to create new users or to group or delete them directly from the application.
