Design Of Wireless Sensing Network System Based On Embedded Platform

With the improvement of people's living standards,there is a realistic need for community security monitoring and intelligent building control,and wireless sensing networks can achieve these functions well.How to improve the transmission rate,reduce the power consumption and break through the limited transmission distance has become the focus of the wireless sensing network system.This paper proposes a research on the construction of wireless sensing network system based on embedded platform and Zigbee technology,and studies the design and implementation process of the system.This paper successfully developed a wireless sensing network system with the Linux embedded platform as the core.The Ubec UZ2400 Zigbee chip with IEEE 802.15.4 standard and the microcontroller MCS8051 were used to develop wireless sensing network communication and control nodes.The MCS51 provides an IO device with a maximum of 16 pins on the peripheral and a set of UART interfaces to adapt to different needs in the future.In the sensing network system part,the embedded system is used to control and record the entire domain name,and the CGI web interface is provided so that the user can monitor each wireless sensing network node through the network connection anywhere.The system can send and receive commands to and from the IO device,and the terminal node sends its information to the embedded system.When the embedded system knows this information and records it at the same time,the correct result can be seen on the web page.The control information can also be accessed through the web page,and the information is sent to the target node via the judgment of the embedded system.The Zigbee standard wireless sensing network studied in this paper effectively extends the standby time of nodes and improves the transmission distance.By using the embedded system as the management host and running the CGI web page on the embedded system,the construction cost is effectively reduced,and the stability of the system operation and the convenience of the manager are improved.Therefore,the research of this subject has very important application value.
