ZIGBEE-Based And Real-Time Database Technology For Wireless Data Acquisition System

The birth of wireless sensor networks had solved the difficulties of wiring the region, members of the region do not reach the issue for data collection, At the same time simplifying the cable network also brought about by the planning layout, the default interface, line detection, line capacity and transmission channels, such as a series of tedious work-related. At present, wireless sensor network market is almost occupied by foreign firms, which seriously hindered the acquisition of China's wireless data systems. At present, as an emerging ZigBee wireless communication technology with a combination of real-time database will be wireless real-time data acquisition system played a significant role in promoting, At the same time, real-time wireless data collection system to enhance the development of the operational efficiency of enterprises, improve the competitiveness of enterprises, reduce operating costs is also a very important role.The main purpose of this paper is to design a set of basic applications to achieve real-time wireless data collection system to validate the ZigBee technology and the fact that a combination of database technology feasibility, in order to lay the foundation for future research. The characteristics of the system is designed to be simple, real-time system is stable. Its functions include data acquisition node for analog signal acquisition, ZigBee wireless network of wireless transmission of data, Real-time database data management, and management features include real-time data display, data mapping curve, data alarm and data storage, etc. Staff can monitor the host computer to monitor data as shown by the system reports, as well as the curve of the measured report to the police state of the corresponding object, the timely and efficient manner. Subject to CC2430 chip ZigBee wireless networking as the core of the entire wireless network to adjust the normal operation of the network; real-time database as the core of PC is responsible for the entire data acquisition system in real-time data storage, network and wireless PC data exchange; configuration software through the wireless sensor networks and real-time database connectivity and generates a friendly man-machine interface,as well as have a friendly interactive interface to facilitate management of data management, data collection site to keep abreast of the situation.In this paper, the major work done:1,in the study based on IEEE802.15.4/ZigBee agreement to build a ZigBee wireless communication network star, achieved ZigBee basic star network applications. 2,the completion of the ZigBee network nodes of the hardware design, including schematic node hardware design, hardware anti-jamming measures node, node hardware, as well as the production of PCB board circuit debug hardware.3,the completion of the network node communication software design, including data collection procedure terminal nodes and each node of the preparation of software designed to communicate with each other to achieve the end-nodes of the collection of ambient temperature, as well as star-shaped network of communication between each node.4,Configuration software through the completion of the wireless sensor networks and real-time database systems, real-time database system for data management, such as: real-time data display, data mapping curve, data such as alarm and data storage.This system's function has been verified.,for example real-time systems, data transmission, as well as the correctness of the stability of the system through many times the actual tests.
