[0002] Traditional preventive measures mainly include manual inspections, video surveillance, alarm systems, etc. These measures can prevent and combat oil and gas theft to a certain extent.

[0003] After searching, the Chinese patent publication number CN113759972A includes: a satellite system, which uses the satellite images provided to pre-analyze the disaster area and screen out the areas that have been affected by the disaster; an unmanned aerial vehicle system, which is used to shoot and collect oil and gas pipeline information and conduct inspections according to the buried routes of the oil and gas pipelines; an inspection vehicle, which is used to receive the images taken by the unmanned aerial vehicle system and send the images to the ground station; if it is found that some pipeline areas in the images taken by the unmanned aerial vehicle system are affected by the disaster, the inspection vehicle is operated to go to the affected area to detect the underground buried oil and gas pipelines, and if the oil and gas pipelines are found to be abnormal, an alarm signal is sent to the ground station. After various disasters occur, the present invention can quickly inspect the oil and gas pipelines in the disaster area, evaluate the status of the oil and gas pipelines, and then determine whether there are safety hazards in the oil and gas pipelines.
