Design And Research On Wireless Remote Forest Fire Prevention System Based On ZigBee And GPRS

With the increased awareness of the people of forest fires, the forest fire prevention technology is also put forward higher requirements. People constantly apply advanced technology to the forest fire prevention system, is the inevitable trend of development of forest protection technology. At present, the forest fire prevention technology still stays in the wireless video monitoring technology level, although it effectively solve the disadvantages of the traditional human management, nursing forest, however, when the forest environmental conditions is more complex, such as wind or fog, its control effect is not ideal. Therefore, this article designs a forest fire prevention system based on Zig Bee and GPRS technology. It not only can solve the problems, but also can add video monitoring to the system when it is used, in order to achieve the enhancement purpose to the effect of objective monitoring system.Firstly, this article describes the design of forest fire prevention system idea and composition, the basic knowledge of Zig Bee technology related to the system, and designs the Zig Bee node hardware circuit and software program. Secondly introduces the basic theory of GPRS technology, the hardware circuit of SIM900 B and SCM procedures, and designs GPRS short message and the gateway between Zig Bee network and GPRS network. And then it summarizes the related technologies used in the monitoring center design, designs the system of the backstage database and the user interface, and has carried on the system of alignment. Finally,the paper pays attention to the key problems of the node deployment,positioning and data fusion.
