| The logistics monitoring system is an important aspect of the modern logistics information construction,it can provide strong technical support for logistics enterprise management information through the vehicle data terminal,wireless communication network and logistics monitoring platform.Logistics monitoring platform is the management center of the whole logistics monitoring system.It uses spatial analysis and decision making technology of geographical information system for real-time monitoring and scientific scheduling of logistics vehicles.Web GIS combination of network technology and GIS technology,the resulting Web GIS is currently one of the hot spots in the GIS industry research.Users can quickly and intuitively access and share geographic information using Web GIS,relative to the logistics monitoring platform based on the traditional GIS,the information sharing of logistics monitoring platform based on Web GIS is more convenient,the load calculation is more balanced,data access is more efficient,and the cost is more economicalIn this paper,we design a set of logistics monitoring system solutions based on Web GIS platform.This scheme greatly reduces the difficulty and cost of developing map,reduce the pressure of server by using Map Xtreme as the development technology of Web GIS.At the same time,a distributed multitier architecture is constructed based on J2 EE system framework,it reduces the code coupling,improves the reusability of the program,and reduces the development cost.The database connection pool mechanism is also introduced to improve the data access efficiency.The scheme is divided into four modules: system setting module,vehicle monitoring module,data management module and data management module.Finally,the scheme is realized by software engineering technology and application and a logistics company,the test shows that the system is far superior to the source system in terms of accuracy and efficiency. |
