Based On The Research Of ZigBee Wireless Monitoring Network System

In modern wireless communication and network technology, the technology is proposed based on ZigBee wireless monitoring and control network technology. As electronic technology and embedded technology, communication technology requirements of the industry is getting high, wired communications technology from the previous to the current wireless communication technologies, particularly the more advanced of the current monitoring and control of wireless network communication technology . Knowledge of wireless technology through, this technology was designed based on ZigBee wireless monitoring and control of the network. ZigBee wireless network is based on the ZigBee technology and constructed a low-power, low cost, high-speed wireless communications network. In the current domestic and international communications industry, wireless network communication technology in all fields has been widely used. In particular, the wireless monitoring and control network technology at home and abroad is a concern in the current research topics. Wireless monitoring and control network technology includes computer technology, communication technology and sensor technology. Currently the field of electronic communications, there are many wireless technologies, such as: Bluetooth, wireless near field communications, UWB and ZigBee technologies. Moreover, ZigBee technology is an emerging wireless communication technology, although the ZigBee technology in the domestic market of late, but based on its low-power, short delay, low-cost, short distance transmission and so on. ZigBee wireless technology in the wireless communications industry is very fast. Therefore, all current wireless technologies in the field, ZigBee technology development very fast. It is mainly used in industrial control, intelligent home networks, defense industry, automotive industry and environmental monitoring.This paper introduces wireless monitoring and control network system development and current research trends at home and abroad. Based on this analysis technique based on ZigBee wireless monitoring and control network technology. Wireless communication technology in a variety of options, the final selection of the ZigBee technology as the core of the basic communications protocol. ZigBee technology introduced in detail the development and background, protocol stack structure, network topology and the CC2430 chip. ZigBee protocol stack and using technology to achieve the wireless monitoring and control network systems. Based on this platform for a tree, star network topology and network type.Second, the study of the wireless network based on ZigBee technology, the working principle and protocol stack structure, and analyzes the physical layer, network layer, medium access control layer and application layer. This selection of the latest chip CC2430 ZigBee chip technology and the use of wireless microcontroller core, HFZ-SmartRF04EB as the main control unit. While CC2430 is configured, set up a low-cost wireless communication module, using RS232 serial communication and PC machines connected to the interface design of communication protocols between them, and use this technology to achieve a simple point to point wireless communication technology test. CC2430 chip through the network and node network and the success of retirement to join the network. Remote monitoring can be achieved among the parameters of the environment, this platform was designed in coordination node, the router node and terminal node binding and data transceiver functions. Verify the stability of ZigBee wireless technology.Finally, combined with the latest ZigBee technology ZigBee communication standard design of the networking mode protocol stack technology. In the laboratory of ZigBee technology, point-based experiments and tree topology wireless communication network experiments, and certainly based on the ZigBee wireless sensor network technology, the feasibility and stability. After the system test software and hardware co-debugging, experimental results show that the design of ZigBee-based wireless communication technology for wireless monitoring and control network, system stability, basically meet all the system requirements.
