Research on the Application of Web Inspection System Based on CORS in City Inspection

摘要

The traditional GPS RTD applied in city inspection has some shortages that inspection information cannot be returned to the control center real-time, data cannot be shared and inspection track cannot be monitored, so this paper designs the Web inspection system based on inverse RTD which adds one Mid-Server between CORS system and PDA, Mid-Server receives differential information and conducts differential correction, then the result returns to PDA which has no differential function, but should increase bidirectional communication module to receive the result returned from Mid-Server and upload the attribute information of inspection points to Mid-Server, indoor workers can get inspection information through Web platform real-time. Testing results indicate that this technology has the advantages that information can exchange real-time, user can use cheaper PDA without differential function and can develop appropriate coping strategies timely, so its application in city inspection can avoid the shortages of traditional technology.
