The Design Of Home Monitoring Terminator Using GPRS Based On Embedded Linux

With the development of computer technology and communication technology, the improvement of people's living standards, new technologies bring the growing of the profound changes in lifestyle. Embedded systems technology, wireless communication technology combined with wireless remote video surveillance system as possible. The many advantages of wireless monitoring will significantly change people's lifestyles and ways of thinking and enrich the family means of achieving security, the future of home security technology must develop in the direction towards the wireless monitoring.Existing wireless radio technology, Bluetooth technology, wireless LAN technology, wireless technology can not solve the transmission distance, transmission rate and cost issues. Has covered a wide range of high transfer rate, access time is short, always online, according to the characteristics of GPRS meter fees are to meet the needs of wireless monitoring system. And also the further development of existing resources, the full utilization of existing resources, but also an important manifestation of energy conservation.The main work as follows:1,Achieved through the principle of GPRS technology and in-depth research, design, embedded Linux-based home control GPRS terminal, the design of the hardware platform, which S3C2410A processor hardware core based on the circuit, including: the clock circuit, reset circuit, power circuit, JTAG interface circuit and the memory expansion circuit; peripheral interface includes: image acquisition module connected with the USB interface circuit, and audio modules in the IIS interface circuit and the GPRS module connected with the serial circuit.2,Complete the monitoring terminal software platform development, Embedded Linux operating system migration: UBoot transplantation, embedded Linux operating system, compiler and transplantation, cramfs root file system build; hardware driver development: NAND FLASH Driver design, the design of the serial driver, USB driver design; of the driver development process and content in detail.3,Control terminal application design, image acquisition module: image compression module implementations; GPRS wireless transmission: GPRS module network, GPRS connection with the PDP context activation, GPRS PPP dial-up access and transfer agreements; short of information and communication: short information processing module to send and receive text messages on the process. Hardware and software platform for integrated test system to verify the effectiveness of the system design.。...
