Researchon On Security Controller By ARM

The security system is a technical prevention system established for the purpose of security.It includes kinds of physical equipment.This equipment,by physical and electronic technology,can detect intrusion damage,have a sound and light alarm to deter criminals recording images and sound to provide a certificate case,remind the staff on duty to take appropriate measure.In recent years,with the development of the national economy,people's living standards significantly improved,the use of security system was increasingly broad.Security industry gets more and more attention.With the development of security industry,there are more and more types of security equipment,security equipment manufacturers are also becoming more.But the provider of security systems are basically independent of the development and in the development of control software,they generally did not consider a wide range of integrated security devices.In order to obtain a wide range of integrated security systems,people to build security systems are often best suited to the purchase of security equipment provider,and then by their own employment or other companies to develop a set of software for their own use,the equipment will be integrated together,constitute a system suited to their needs.While it is free to choose a variety of outstanding security equipment,has a great deal of flexibility,but also have bring a lot of problems to the management and maintenance of equipment.Based on the problems of current security system,this paper designed a security controller.Adding a series of such controller in the security system,the whole security system is divided into pieces of small security unit which is easier to manage and maintain.This small security unit can be a separate small-scale security systems under the management of security controller,but also with other security units and upper management platform components together into a comprehensive security system.In this paper,the security controller is a small and intelligent management controller.It bases on the ARM core processor chip,the software of controller embedded in the Windows CE operating system platform.And considering the compatibility with security equipment and the expansibility of controller function,the software of controller us athree-tier framework.The descriptive process of this paper as follows:ChapterⅠ:The security of the system and the principle of building and the components of the security system,introduce the current situation and development trend of security system.ChapterⅡ:introduce Windows CE embedded operating system and it customization,make foundation for the selection of hardware controllers and software designed.ChapterⅢ:The overall design of the structure of security controller focuses on the associated hardware. ChapterⅣ:The upper programs of the controller of,introduce the detailed design of the controller application interface layer and the central control layer.ChapterⅤ:introduced USB and serial port communication in the WINCE-driven communications structure,and the achievement of the interface class of control equipment layer.The main task of the author is to:1.Custom and install Windows CE embedded operating system for the security controller.2.Research on overall design of security controller.3.Research the interface application layer and the central control layer of the controller software.4.Research the interface class of device and the corresponding device based on the ARM9 platform WINCE Embedded System environment.
