The GPN pipeline crawling endoscope is one kind of collection modern optics precision machinery electronic technology computer technology may revolve 360 degree to body photoelectricity instrument this instrument camera in the pipeline to turn over 180 degree to be able to carry on the inspection to each kind of pipeline internal surface specially to be able because to wash out to the long-term use the fluid the mechanical crack and the corrosion perforation pipeline which function and so on electrochemistry corrosion appears carries on not damages the examination to be able to avoid finally causing the transportation efficiency to reduce accident the and so on transportation medium revelation occurrence therefore uses in the pipeline to crawl the endoscope to carry on the periodic inspection to each kind of pipeline promptly to discover in the pipeline appears the flaw and carries on the service not only to be able to avoid the accident the occurrence enhancement working efficiency also bringing significantly The economic efficiency and in the social efficiency pipeline crawls the looking glass controller to use the portable operation handle with to grasp the liquid crystal display monitor integration also to be able to observe on the picture control power source during operation to have the video output to be allowed to connect the monitoring device or the computer enters the picture processing system.
