Research on State Interactive Diagnosis and Assessment of Power Cable Lines in Utility Tunnels based on Mobile Sensing System

This paper discusses research and trial application of mobile sensing and interactive diagnostic technology for power cable lines. The comprehensive construction of intelligent operation and maintenance system combined with the modern information technology, intelligent technology and the traditional technique is an urgent demand. The mobile sensing and interactive diagnostic technology for power cable lines integrates technique of conventional statue detecting, on-line monitoring, tunnel monitoring and patrol robot, supported by the internet of things technology and combined with RFID technology, individual mobile terminal technology, multiple states sensing technology, patrol robot technology, the distributed diagnosis technology and data interactive technology. The whole system makes operation staffs conveniently acquire operation indicators and preliminary analysis of power cables lines and tunnels in the process of patrol and maintenance, master and update realtime operational information of power cables lines and tunnels, such as operating state, fault prediction, risk level and maintenance recommendation by communicating with control center platform. Further application of the technology will innovate maintenance mode and promote intelligent level, efficiency and effects of operating management and maintenance of power cable lines comprehensively.
