ZigBee Of Wireless Location-based Application

ZigBee is a wireless positioning system detected by the signal strength to calculate the coordinates of the mobile node information corresponding to the map coordinates of a position to know the current location of mobile node. Before work in the system need to deploy and configure the entire system, major components, including the reference node configuration, location and the coordinator node, configuring the parameters, the system will be timely collection reference node coordinates and signal strength information to calculate the coordinates of the mobile node information and then coordinate messaging mobile node to the Analysis Server, Analysis Server Wireless Location Manager in analysis of these data, the mobile node can generate the specific location on the map information, by observing the location of mobile node changes, managers can learn real-time production operations and personnel activity status information, which can make the process work more safely and efficiently.Test results show that the positioning accuracy is 5m, the best set of test data, the error is only 0.3m, so the accuracy of its credibility is relatively high, however, through the ZigBee protocol wireless location solution is feasible. This article mainly includes the following:Introduction describes the significance of wireless location system and the research status and development trends, and cited the more popular current positioning system was implemented.System design in part by the composition of the hardware and software design. Hardware design parts, hardware features, communications frame format used when positioning theory and the respective description is given. Software design gives the overall system architecture design, function and implementation of various components, the last part also focuses on the introduction of the system processing core module, and put forward the improved location algorithm. System design part is the focus of the full text, through which part of the system has to know the function, function realization principle, and the whole system process. Through system design and implementation, and testing we got the final conclusions, and some improvements later thinking.
