Design Of Configuration MAP Service And Its Application In Sensor Device Management

With the gradual integration of Internet of Things(IOT)applications and geographic information system(GIS)technology,it becomes a major trend to apply network GIS to sensor management in the IOT environment.Web map service(WMS)is an important part of GIS.The combination of WMS and IOT focuses on location-based sensor management,but visualization of real-time dynamic updates of sensor data is not implemented.Configuration technology is a key technology for Internet of Things applications,mainly be used in real-time monitoring and control of the actual situation in industrial field,and has been gradually applied widely.Therefore,the WMS and configuration techniques are put forward to realize the real-time dynamic update of sensor data for visualization and provide a more convenient and quick method for the sensor device management.This paper analyzes the current status of WMS management of sensor devices and real-time monitoring of configuration technology,and studies WMS and configuration technology and realtime visualization of sensor data.First of all,by analyzing the characteristics of SVG graphic elements,this paper designs SVG as the WMS map output format,based on the traditional SVG map symbols,combined with the configuration technology WMS has been extended,based on the sensor data and SVG map The mapping rules of symbols form the specific mapping between the sensor data and the graphic elements in the WMS map instance and realize the change of the map graphic driven by the change of the sensor data through the script.Then,using the Geo Tools tool to achieve the process of publishing the WMS,the server compiles mapping rules of the map symbols and the sensor data into scripts during the process of configuring the WMS to form the map instance of the map.When the sensor data changes,the configuration WMS instance uses scripting to change the drawing parameters of the SVG map symbol,so as to realize the real-time dynamic update and visual expression of the sensor data.Finally,the performance of WMS configuration test,study the test program,the traditional WMS and configuration WMS test results were compared.The thesis verify the application of WMS method in sensor management system.The design framework of this sensor management system is Spring MVC and Hibernate.Complete the function display of the sensor management system,realize the operation of adding,deleting,checking and correcting the sensor in the system and real-time visualization of the sensor data.The experimental results show that the configuration map service not only can utilize geospatial data to publish maps to meet the needs of basic map operations,but also can obtain real-time dynamic data of sensors and real-time visualization of sensor data on the map.The combination of configuration technology and WMS can be widely used in real-time communication and monitoring management of sensor devices in the environment of geographic information systems.
