In recent years, the development of intelligent robots has been more and more advanced, and the results have been well developed in various fields, so that it has been proposed to use an intelligent inspection robot instead of a human to perform work for the above technical problems, but there are many problems when using an intelligent inspection robot instead of a human, such as:

1. the power supply power problem of the robot, when the robot carries out work in the GIL pipeline, because the robot self volume is limited to the function that needs to accomplish is more, therefore the electric power very easily appears inadequately.

2. When the robot needs to be overhauled, the sealing cover of the GIL pipeline still needs to be manually opened to put in or take out the robot, which is contrary to the original intention.

3. Because the GIL equipment is all metal shielding, therefore, the robot of present patent all need to carry out the exhaust to GIS or GIL equipment in using, and the processing of uncapping just can ensure control signal's transport.

It can be seen that there is a need for a device that can interact with robot information without opening the pipeline.
