Description

Technical Field

[0001] The present invention relates to the technical field of oil and gas data, and in particular to a method for uploading comprehensive data of an offshore oil and gas platform in real time using a single optical fiber. Background Art

[0002] The ocean is rich in oil and gas resources, and the intensity of oil and gas development in the ocean is increasing. With the discovery of offshore oil fields, the number of offshore drilling platforms is increasing. The number of offshore drilling platforms reflects the development strength of a country's offshore oil and gas resources, and the comprehensive data of offshore oil and gas platforms often needs to be uploaded.

[0003] The rapid development of data processing technology and sensor technology has made multiplexing and high-definition a trend in data application development. The surge in the amount of comprehensive data not only poses a severe challenge to the computing power of the processing platform, but also creates great difficulties for the high-speed transmission of data between chips in the processing architecture.

[0004] Moreover, when data is generally transmitted through a single optical fiber, a large amount of data influx easily causes data accumulation, and the reliability of data transmission is not high. Therefore, a single optical fiber real-time upload method for comprehensive data of an offshore oil and gas platform is proposed. Summary of the invention

[0005] 1. Technical issues to be resolved In view of the shortcomings of the prior art, the present invention provides a single optical fiber real-time upload method for comprehensive data of offshore oil and gas platforms, which solves the problem that a large amount of data influx easily causes data accumulation when data is generally transmitted through a single optical fiber, and the reliability of data transmission is not high.

[0006] (II) Technical solution To achieve the above object, the present invention provides the following technical solutions: A method for uploading comprehensive data of an offshore oil and gas platform in real time through a single optical fiber comprises the following steps: S1: Data collection, collecting images, videos, texts, and voice data from offshore oil and gas platforms; S2: Data preprocessing: Separate the collected voice data and video data according to the frequency band and time node, and complete the format conversion during the separation process; allocate multiple buffer queues to the transceiver buffer queues on the coprocessor and the core processor, and predefine the target data storage address of the core processor; S3: Internal transmission, when there is no less than one segment of data in the buffer queue and there is no read request at this time, the data is sent. When the coprocessor sends data to the core processor, when the transmission of one segment of data is completed and there is no read request at this time, a response operation is sent to notify the core processor to process the received current segment of data; when the coprocessor reads data from the core processor, when the core processor has processed two segments of data, a response operation is sent to notify the coprocessor to read the first segment of data. The amount of data in the buffer queue received by the coprocessor and the response operation sent by the core processor to the coprocessor are used as trigger conditions. When there is more than one segment of remaining space in the buffer queue, a read operation is formed to complete the reading of one segment of data; S4: Setting up a transmission channel, placing two unidirectional optical fiber data transmission cards at the transmitting end and the receiving end of the data transmission equipment on the offshore oil and gas platform respectively, and connecting the two unidirectional optical fiber data transmission cards by a single optical fiber through an optical fiber transceiver, thus completing the setting up of the transmission channel; S5: Single optical fiber transmission, the data to be transmitted in the core processor is transmitted through the transmission channel set up; S6: Add a packet header. When sending data, the sender adds a private protocol information packet header to the data to be sent; S7: Data parsing. After receiving the data, the receiving end parses the transmission packet header information and determines whether it can be recognized during parsing. If the format cannot be recognized, the data is discarded and a warning is issued. If the format can be recognized, the correctness of the data is verified using the transmission packet header information. If it is correct, the data is continued to be transmitted. If it is incorrect, the data is considered to be damaged during transmission and is discarded. S8: Data isolation: A 0° WDM filter and a hemispherical lens are set at the receiving end to isolate the optical signal.

[0007] As a further solution of the present invention, the data collected in S1 includes basic data and reference data, the basic data includes integer type, floating point type, character type and Boolean type, and the reference data includes type and interface type.

[0008] Furthermore, the S5 includes an amplification module, and the amplification module amplifies the optical signal through an amplifier.

[0009] On the basis of the above scheme, in S5, a timer is set during data transmission. When a data transmission request is received, no response request is made immediately, but the timer is started and a waiting period is entered. If the data corresponding to the request is detected to be updated during the waiting period, it is updated immediately and the updated data is transmitted to the client.

[0010] Furthermore, the private protocol information packet header in S6 includes but is not limited to the data length of the data to be sent, the data source, the destination to which the data needs to be sent, and version information.

[0011] As a further solution of the present invention, when verifying the correctness in S7, the verification information obtained by calculating the data is consistent with the verification information carried in the data packet header information parsed from the data. If they are consistent, it is judged to be correct, otherwise it is judged to be incorrect.

[0012] (III) Beneficial effects Compared with the prior art, the present invention provides a method for uploading comprehensive data of an offshore oil and gas platform in real time using a single optical fiber, which has the following beneficial effects: 1. In the present invention, multiple buffer queues are separated to avoid the situation where the data processing program cannot process all the data when the data volume is too large, resulting in data accumulation and congestion of the transmission link, saving the transmission overhead of a large amount of data between chips, reducing memory resource usage, and reducing software and hardware design.

[0013] 2. In the present invention, the optical signal is amplified by an amplifier so that the stimulated light is taken into the optical fiber together with the signal light beam, and the signal light beam is amplified, thereby improving flexibility and reducing costs. It can ensure that the data can be sent to the client in time when it is updated, that is, the real-time performance is guaranteed, and avoid the waste of server resources caused by the client constantly and regularly sending requests to the server.

[0014] 3. In the present invention, by transmitting packet header information, it is possible to determine whether the data transmission process is damaged and accurate, thereby ensuring the reliability of data transmission during large-scale data transmission, improving the transmittance of working band optical signals, and effectively isolating non-working band optical signals, thereby greatly improving communication quality.
