[Abstract]:In recent years, with the rapid development of information technology such as computer and network communication, multi-function, low energy consumption, miniaturization and low cost embedded wireless terminal equipment have been widely used in the fields of environmental monitoring, security protection, industrial control, intelligent home and medical care. This lesson is designed to meet the needs of users, that is, rapid development of wireless sensor terminals. The ZigBee wireless protocol module XBeePro. is used to define the details of the physical layer PHY and the media access layer MAC. The network layer NWK can provide the application interface function for the application layer APL to serve the [1].ZigBee protocol technology because of its specification, maturity and high security. As one of the important technologies of wireless sensor networks, technical characteristics are widely used, and its development prospects are very broad.
This paper, based on S3C6410 development board, embedded Linux platform, connects ZigBee wireless transceiver module XBeePro, CMOS camera OV9650, designs and develops embedded wireless terminal equipment and sets up wireless sensor network, realizes the real-time monitoring of the target site and uses ARM11 kernel architecture in the kernel of.A3C6410 processor, and its extended interface can be used with CM. OS camera OV9650 and wireless module XBeePro are convenient to connect; the open embedded Linux platform provides great convenience for the transplant and development of applications.
This paper systematically analyzes the principle of ZigBee protocol stack, the development environment of embedded Linux platform, the use of V4L2 interface and LIBJPEG library, and the use of Linux network programming technology to control the acquisition, processing and storage of the terminal equipment through the instruction and receiving of instructions, and realizing the transmission of the image on the TCP/IP network architecture; and using the Linux system. The serial port programming technology controls the ZigBee wireless module, and controls the terminal equipment to accomplish the above process by sending and receiving commands, and realizes the transmission of images on the wireless ad hoc network.
