Aiming at the problem of low efficiency and high cost in the current oil and gas pipeline detection equipment location system, a location management system of oil and gas pipeline detection equipment based on APP is proposed. The system can automatically real-time detect the whether the equipment has passed the set point in real time and passes the location map of equipment and related information to the sever of project management side. At the same time the information is passed to the engineering staff in order to let them know the equipment position. Therefore this system can greatly reduce the labor intensity and cost, improve work efficiency, facilitate the management and have a good value of promotion. Induction The oil and gas pipeline has a very important position in the energy transportation. With the increase of energy demand in China, the exchange between China and energy producing countries is becoming more and more frequent, therefore the construction quantity and demand of long distance oil and gas pipeline are increasing gradually [1-4].To the end of 2015 the total mileage of China's onshore oil and gas pipeline is up to 120 thousand km [5, 6]. In order to ensure the normal operation of oil and gas pipelines, the detection equipment is needed to detect and clean the pipeline regularly [7]. Pipeline inspection equipment needs real-time positioning in the process of operation. When the equipment fails, pipeline defects and other conditions needs to be positioned timely and accurately in order to take measures to eliminate the trouble [8-10]. The existing positioning system of oil and gas pipeline detection device is still backward in engineering practice. Because oil and gas pipeline detection device is always running, its position needs to be determined in time to avoid device failure. Traditionally, workers use cars to carry many receivers and lay the receiver along the pipeline at a certain distance. Once the oil and gas pipeline detection device through a certain receiver, the receiver will alarm and notice staff the device has passed this point. Then the receiver is taken back. This method is repeated until the end of the test. Another way it to set and shallowly bury the receiver along the pipeline at a certain distance. The marker for staff identification is inserted at the location of buried receiver. According to the operation speed of the device, the staff can estimate about what time to reach which receiver and then go to see whether it has passed. If a receiver is not passed within a predetermined time, blocking phenomenon may occur. This requires staff to take the receiver to find the specific location of oil and gas pipeline detection device in the blocking distance. In this way the workload is still small in short distance, but it will be unimaginable when the pipeline distance is less than tens of kilometers, more than a few hundred kilometers and even thousands of kilometers.
