The angle being supported on inner-walls of duct, and second camera is opened, second camera alignment fault location is precisely shot, is obtained
The picture of defect is taken, on the bank after control system display defect data, return unit will be balanced in empennage income housing, and bascule is extensive
Initial condition is answered, then technical staff's continuation control diving robot advances in the duct, completes the pipe detection of the pipeline section, then
Same pipe detection is carried out to next section of pipeline section；
(e) defect location and maintenance：For the data in control system on the bank, image detection, editor, note is carried out to pipeline inside
Record, playback, position real time record to defect of pipeline, confirm the classification of defect of pipeline, it is determined that the elaborate position of maintenance, arranges exclusive
Technical staff carries out maintenance work.
8. a kind of sewage network according to claim 7 is dived under water robot detection method, it is characterised in that：It is described to set up pipe
In road information station operation, the length range of pipeline section is detected in 0～120m, length is accurate to 0.1m.
9. a kind of sewage network according to claim 7 is dived under water robot detection method, it is characterised in that：The subaqueous pipe
In road detection operation, the speed of a ship or plane of the diving robot is controlled in 0～10m/min, and the diving robot is in underwater operation
Time control is in 0～1.5h.
10. a kind of sewage network according to claim 7 is dived under water robot detection method, it is characterised in that：The defect
In positioning action, the location positioning precision of defect of pipeline is 1cm, and the scope of positioning resolution is in 0.05～0.1m, pipeline detection
Distance is 150m.
