Design Of Remote Gateway Based ARM

Along with the communication and networking's development, we causes through the network to be possible very convenient to carry on the long-distance real-time monitoring to the scene. The remote monitoring's significance is not only can complete under the adverse circumstance the monitor task, can the very convenient constitution wireless sensor point, omit wiring troublesome at the same time more importantly also to be able according to the function demand fluctuation point.In the remote supervisory system, the remote gateway is at the core position, is various terminals point always controls the platform. Therefore the remote gateway's design is very important. This article mainly introduced one kind independently designs based on ARM processor's remote gateway system's concrete realization. The paper main research work is as follows:Acts according to the remote supervisory system's request, the development remote gateway system. First takes ARM7 TDMI nucleus 16/32 RISC processor S3C44B0X MCU, and completed various periphery chip shaping which according to the S3C44B0X characteristic the system needed, the hardware design has mainly included: CPU module, GSM module, pronunciation module, Jennic module, keyboard and LCD module. Completes Bootloaer in the hardware platform foundation the transplant, the uClinux reduction and the transplant, the first floor driver design as well as the correlation application procedure design, and has designed the driver for each main periphery module, built system's software platform. How in view of the Zigbee network and the ethernet close fusion's question, this article proposed one kind based on ARM the platform Zigbee gateway's design proposal, in studies the Zigbee protocol standard and the Zigbee equipment and in the network foundation, has completed based on the ZigBee agreement stack's wireless module procedure development, causes between the net the address, the agreement to unify in the application layer and very easy to expand to other networks. Finally separately joints shake down testing two aspects from the hardware debug and the software and hardware to test the gateway system's reliability and the stability.In brief, this article develops the remote gateway's design proposal while satisfied between the net data exchange highly effective, transparent also to realize the easy extension.
