The Study And Implement Of Multi-functional Communication Terminal And Short Message Service Based On ARM

At present, wired image monitoring system is widely used in the field of imagemonitoring system, but the function of wired image monitoring system is to be restrained inlocations where equipments are widely distributed, where is so remote that no people tocollect data. However, with the development of mobile communication technology, theWireless Remote monitoring system gradually broke through such limitations. This paper putforward a multi-functional communication terminal used in remote data monitoring system.This multi-functional communication terminal uses the ARM processor as the coreand usescamera to capture picture and transfers data through GPRS network thus to achieve thepurpose of remote monitoring.In this paper, according to general application of the monitoring system, it put forward aset of design applicable multi-functional communication terminal to remote wirelessmonitoring system. Through the establishment of embedded Linux cross compiler, compiledevelopment-board U-boot, Linux kernel transplantation and clipping, making Linux root filesystem to complete for embedded Linux development platform. On this basis, it realized USBcamera data of camera collection process based on V4L2. In-depth analysises of the SMSsending and receiving process and coding standard, it implemented completely the design ofSMS module. It raised a transmission module of MMS data by use of the GPRS networks toaccomplish image data transmission based on the protocol of WAP.The entire system includes the design and the implementation of the hardware structure,the software system and the application software. This time, the hardware design ofMonitoring System is consist of the series of ARM9’s processor called S3C2440produced bySamsung Corporation as the core, USB camera with the chip of ZC0301, and the GPRSmodule SIM300from SIMCOM. It accomplished the function of the realization of wireless system transmission.
