    INTELLIGENT SYSTEM AND METHOD FOR INSPECTING OFFSHORE OILAND GAS PIPELINES
    TECHNICAL FIELD The present invention relates to the field of pipeline geographic information measurement technologies, and in particular, to an intelligent system and method for inspecting offshore oil and gas pipelines.
    BACKGROUND Pipelines are not only important carriers for transporting various onshore and offshore oil and gas resources, but also the fastest and most economical and reliable transportation method at present. However, most pipelines are buried underground or under the seabed at a certain depth. Underground pipelines are susceptible to terrain changes caused by man-made excavations and natural disasters. Submarine oil and gas pipelines work in complex marine environments. Subject to high pressure and salinity, large temperature differences, and erosion of biological growth for a long time, these pipelines can be easily corroded, damaged, and cracked. Failure to promptly detect pipeline damage can not only lead to huge economic losses, but also cause immeasurable damage to the marine ecological environment.

To achieve the above objective, the present invention provides an intelligent system for inspecting offshore oil and gas pipelines. The system includes a controller, an underwater inspection device, and a storage device. The controller is communicatively connected to the underwater inspection device in a wired manner.

    Preferably, the controller is communicatively connected to the underwater inspection device through an umbilical cable.
    Underwater communication using medium- and long-distance umbilical cables allows data exchange between a local area network and the underwater inspection device. When the underwater inspection device cannot be controlled or the communication is interrupted by accident, it can be manually pulled back by using the umbilical cable to avoid property loss. A length of the umbilical cable can be adjusted based on an underwater pipeline depth.
    Preferably, the controller includes a plurality of data acquiring channels for receiving the underwater pipeline information acquired by the underwater inspection device for parallel processing. This accelerates data processing.

The drive module is configured to drive the movement of the underwater inspection device.
    Preferably, the underwater inspection device further includes a housing made of a transparent polyvinyl chloride material. An antifouling paint is further provided on the surface of the housing.
    The transparent polyvinyl chloride material has stable physical and chemical properties and certain mechanical strength. It is heat- and pressure-resistant and is difficult to be corroded by acids and alkalis. The antifouling paint can prevent various subaguatic organisms from attaching to the surface of the housing of the underwater inspection device and affecting normal operation of the underwater inspection device.
    Preferably, the controller is further connected to a smart terminal through a network. The smart terminal receives, through the network, underwater pipeline detection information sent by the controller.
    In a specific example, the system uses the spreadsheet function of the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) to store, read, and write data. Data information obtained after processing is saved on the storage device for big data and cloud computing analyses to implement data fusion. In addition, the system further supports historical data query. The data information on the controller 1s uploaded to the storage device. The smart terminal reads the data information on the storage device through the network for display. Specifically, the storage device includes a remote database cloud and/or a network server.
    The present invention further provides an intelligent method for inspecting offshore oil and gas pipelines, including the following steps: A controller sends a control command to an underwater inspection device based on a preset parameter, and controls the underwater inspection device to acquire underwater pipeline information.
    The controller receives and processes the underwater pipeline information, and displays and saves data information obtained after the processing.
    The controller compares the preset parameter with the data information obtained after the processing, and outputs and displays alarm information when the data information obtained after the processing is greater than the preset parameter. Critical valves of a plurality of pipeline information parameters are set. The controller sends the alarm information to prompt a user when the acquired pipeline information data exceeds the critical values.
    Preferably, a smart terminal reads, through a network, the data information saved by the controller.
    Preferably, the controller uses a plurality of data acquiring channels Lo receive the underwater pipeline information acquired by the underwater inspection device for parallel processing.
    Preferably, the controller is communicatively connected to the underwater inspection device through an umbilical cable.
    Underwater communication using medium- and long-distance umbilical cables allows data exchange between a local area network and the underwater inspection device. When the underwater inspection device cannot be controlled or the communication is interrupted by accident, it can be manually pulled back by using the umbilical cable to avoid property loss. A length of the umbilical cable can be adjusted based on an underwater pipeline depth.
