[Abstract]:As the key equipment of offshore oil and gas exploration, the reliable and stable work of underwater production system is the premise and guarantee of underwater safety production. The underwater control system can collect the parameters of seafloor production process in real time and upload it to the water control station to realize the real-time monitoring of the working condition of underwater production. Power line carrier communication is to modulate the data information to a certain frequency of high frequency carrier and coupling it to the power line for transmission and transmission. Therefore, the power line communication transmission technology based on umbilical cord cable can adapt to the working characteristics of deep water production system. It not only solves the problem of long distance transmission, but also reduces the complexity of submarine wiring and saves the production cost. However, the research of underwater power carrier communication technology in our country is still in its infancy. In this paper, the research on underwater power carrier technology is carried out, and the following gains are obtained: (1) the topological structure of underwater production system is introduced. This paper expounds the function of each node module of underwater power carrier transmission, and analyzes the influence of EPU, umbilical cord cable power line and underwater control system modulation and demodulation on underwater power carrier data transmission. The characteristics of underwater power communication are summarized. (2) based on the discussion of spread spectrum and orthogonal frequency division multiplex (OFDM) communication technology, the spread spectrum phase modulation carrier chip Mi200e and the main control single chip microcomputer are selected. The hardware circuit of underwater power carrier data transmission system is designed. After the sensing signal on the oil tree tube is collected by the main controller through the signal amplification circuit, the A / D conversion is carried out, and the data transmission between the main controller and the carrier chip is realized by using SPI serial communication. The carrier chip modulates the received data by QPSK, and passes through the Mi200e built-in power signal amplification circuit and the designed narrow band filter coupling circuit. The transmission and reception of data in umbilical cable power line is realized. (3) based on the analysis of the communication protocol of carrier chip Mi200e, the transmission and reception flow of underwater power carrier communication is described in detail. According to the transmission characteristics of the power supply network, zero-crossing detection technology is used to send three data packets in AC half-cycle 10ms. To ensure the reliability of data transmission. (4) in the experimental test part, the serial port debugging assistant software is used to debug the system, and the circuit parameters are fine-tuned by collecting waveform analysis. The change of load characteristics has a great influence on the amplitude of the waveform, but the waveform is complete, which achieves the purpose of QPSK phase modulation. Finally, the feasibility of the design is proved by the operation and debugging of the underwater data transmission system. The whole system realizes the acquisition of seven sensing signals on the pipeline of the oil production tree model, and the accuracy is more than 0.2. The stability and reliability of the system are verified by the continuous operation of the system in the whole underwater test platform for a long time.
