Abstract


As the development of communications and information, network, physical electronics and other electronic technologies, the use of electronics on measurement and testing physical quantum of the real world becomes more and more popular. Using communications and networks to monitor and control environment has been widely applied. With the rapid development of the Internet, it provides a timely and convenient way to get the latest information, for its access can be at anytime and anywhere. It is this convenient way for WSN to achieve transmission of collected information to the control center, where the information is processed and treated and showed to reflect the real situation. WSN obtains information by distributing the sensor nodes in a certain region, where WSN builds wireless network by wireless to transmit the collected information. And then the information is gathered and sent into Internet.This article focuses on data transmission and processing of WSN and its flow. Three main transport modules are included: Data communication of WSN based on ZIGBEE protocol and its test tools of data transmission, UART communications between data transfer device and sink node, remote communications and network PC programming and their related theories. As these three modules communicating with each other and operating well, data transmission system of WSN is built up. Ultimately, the physical quantum of the real world is displayed and saved at our PC software, and valuable computing is carried out, that intelligent human-computer interaction is achieved.This system was implemented in numerous filed tests, and had showed its reliability, stability, real-time data transmission and so on. The data transmission system has been achieved by target if it is used in environmental monitoring. And the frame of its PC software can be widely used in great data transmission program in Internet. The system has great prospects on applications of modern intelligent control.
