Research And Design Of Embedded Image Monitoring System Based On GPRS

With the rapid evolution of digital image and embedded computer, embedded image monitoring system becomes a new researching interest. Nowadays the wire monitor systems occupy the monitor system market.But the applications are limited by the physieal disadvantages in some difficult situations,such as the monitors, points distribute broadly.The wireless monitor systems are the just solutions . This paper deals with the exploiter of a wireless image monitoring system based on GPRS .GPRS is based on Packet-switch, it only occupies wireless resource when there have data transfer and receive.Wireless data transmission system based on GPRS can realize long- distance data transmission, and this mode is very easy and flexible for combining network.The monitoring system described in this paper is based on S3C2410 and WinCE.The system is composed of an embedded host an USB camera and a GPRS modem, takes charge of image gathering, processing and transmission.Firstly, this paper introduces characteristic of the GPRS technique then briefly presents the system's realization scheme.Based on this,the whole system design is divided into hardware design and software design two parts.In hardware design part,explains especially the inierface of S3C2410 CPU chip with memory and network controller chip.The software design is divided into the migration of embedded Real-time Operation System in detail and application design. Analyzes the design of BSP, it coniains BootLoader, OAL, and so on, and then some functions in BootLoader are shown in this part at migration of embedded Real-time Operation System. Introduces the cut out of operate system, the buildup of SDK and the development of the camera driver.At last this paper explains especially the design of data transmission in GPRS.Finally, experiment result shows that the system realizes the function of remote monitor and control in GPRS and reaches the predetermined target.
