Considering the problems such as lack of real-time monitoring for robot, unified management in signal and video data for the traditional monitoring system, a new kind of remote monitoring system for inspection robot is developed based on C#.NET framework, including C# language and SQL Server2008 database technology. It was used of local area network (LAN) as the network platform and TCP/IP as the network protocol. The system was designed in modularization and feature-based. It was composed of precision location module、sensor status display module、pose status display module、power display module、automatic and manual control module、database management module and video monitoring module, and etc. These modules were respectively designed and the implementation process was given. The practical test result shows that the system has strong real-time performance, good stability and good human-machine interaction (HMI) function, which can meet the functional requirements of inspection robot remote monitoring system.
