Research And Implementation On Visualized Monitor Technology For Indoor Real Time Location Systems

Real-time positioning system are widely used in the asset management, production line automation, traffic control and other fields. In real-time location systems, visual monitoring is an important feature. With the development of Zigbee technology, Zigbee-based indoor positioning system are becoming more and more . As the Zigbee network capacity is large and has the self-organizing feature, how to visually display the position data of ZigBee blind node and track position in the map is a serious problem. In addition, Zigbee-based indoor positioning accuracy is about 2-5 meters, in a complex indoor environment; it needs to increase the detection of RFID-based point to correct positioning error. By setting an RFID-based detection point in the important position in the indoor environment can achieve monitoring of persons and asset. How to mark test points on the map and monitor the area, how timely processing of location data from the Zigbee and RFID monitoring data triggered by monitoring events, how to detect and locate events and handling events and monitoring the timing of events and other business association, is the visualization monitoring technology of real-time indoor positioning system need to be resolved.To address the above issues, this paper in the backround of the indoor Real Time Location System for the actual project development, studies such as visual display method of monitoring objects, Eagle Eye diagram navigation, complex event processing, visual surveillance monitoring and other key technologies, and in this based, design and implemente visual monitoring subsystem and event processing subsystem. Visual monitoring subsystem with test points and the logical area drawing, real-time location point display, location data history path replay, Hawkeye map navigation and other functions; event processing subsystem has wizard-style event subscription and monitor alarm and other functions. Finally, the article describes the visual monitoring subsystem, test of event processing subsystem and the application of the babysecurity system in the hospital. The results of test and pplication show that the visual surveillance technology is feasible and effective. Compared with other systems, this paper has the following features:(1)Propose a checkpoint monitoring mechanism combining with Zigbee and RFID regional monitoring. Including visualized configuration and run-time editing of detection point and its monitoring range in the vector map; Zigbee positioning data of monitoring object in vector map displaying and monitoring of objects with RFID location data correction.(2)Propose personal and asset monitoring mechanism based on complex event processing engine.personal and asset location data become monitoring event, with CEP Engine.Find and process monitoring events and the timing of events and other business association.(3)Design and implement a visualized indoor Real-time location system, which based on the mechanism above, with Eagle-eye map navigation.This system is used in a hospital for baby security.
