[Purposes]This paper introduces a power tunnel monitoring and inspection monitoring system,which aims to solve the problems of low level of intelligence,low operation and maintenance efficiency and high danger when overhauling the operation and maintenance status of cable transmission channels and carriers in urban power tunnels and comprehensive pipe corridors.[Methods]By circulating current and optical fiber temperature measurement online monitoring of the cable body in the tunnel,the system completes the real-time collection,analysis and early warning of cable data and enhances the reliability of power cable operation;by carrying out status perception and control of supporting equipment such as video surveillance,environmental temperature and humidity,toxic and harmful gases,access control,drainage,fans,and lighting in the tunnel,the system improves the intelligent level of the tunnel environ-ment and auxiliary equipment.In addition,the mobile inspection equipment can measure the infrared tem-perature of the cable and conduct self-inspection according to the inspection task,thus enhancing the abil-ity of intelligent inspection and rapid response.[Findings]Based on the B/S architecture,the system,wide spreading and easy to maintain,is able to realize the simultaneous operation by multi-user and multi-touch,which is more user-convenient.[Conclusions]Electric tunnel monitoring and inspection monitor-ing can quickly improve the operation and maintenance overhaul ability of power tunnel auxiliary equip-ment as well as cable transportation,and achieve intelligent and efficient operation and maintenance over-haul in power tunnels.
