The Design And Development Of A Mobile Operational Control Instrument For Deck

Facing the increasing depletion of land resources and from the pressure ofincreasing energy demand, marine resources began to concern for countries, hasbecome an important strategic base for national economic development. With therapid development of offshore oil and gas exploration technology, the CSEM methodis paid more and more attention in the marine oil and gas exploration. Method offoreign research institutions and related oil and gas company application of controlledsource electromagnetic exploration has reached the practical level in technologyresearch and development, equipment manufacturing, but foreign for marine oil andgas exploration only provide related technical services do not provide equipment.However, our country began marine controlled source electromagnetic explorationmethod is relatively late, equipment manufacturing and foreign some distance.Therefore, developed with independent intellectual property rights of the marinecontrolled source electromagnetic exploration equipment has become an importanttask at present.This thesis is supported by national high technology research and developmentprogram (863Program) subject "marine controlled source system equipmentdevelopment and theoretical research" and the Shandong province science andtechnology development project "deep field observation system key technologyresearch", the method of CSEM, according to the project requirements and convenientoffshore construction site and to meet the needs of the instrument timing, school andother special requirements, design and implementation of deck mobile controllersystem function more perfect.This paper introduces the deck mobile controller function definition, systemplanning, deck controller hardware circuit design, software design, man-machineinterface programming and program design. The main function of deck mobilecontroller includes: a signal waveform generating function, GPS timing, timingfunction, wireless data transmission function, high speed data export and storagefunction. The system controller is used in the STM32F series processor ofSTMicroelectronics. According to the acquisition station clock synchronization workrequirements, the GPS timing method. For the construction operation convenient seafield, radio transmitting command, with access to the transmission of large amounts of data. For large amounts of data recorder acquisition requirements quickly deducedelectromagnetic problems, using USB method to realize the high speed. At the sametime in order to ensure the data fast, reliable storage, flexible static memory controllerwith STM32F207processor provides the hardware (FSMC) interface and the externalstorage medium is connected with the CF card, file operating system software datastorage. Based on the relevant functions, in order to reduce the power consumption ofthe system, considering the low power consumption chip and module in the deviceselection, at the same time in the equipment is arranged in the normal mode, sleepmode.Finally, the deck mobile controller related physical map and system debuggingand testing results are given. The test results show that, the good performance of thesystem, the flexible of man-machine interface operation, can be effective in themanagement of related equipment acquisition stations and improve the efficiency ofthe operation of offshore engineering. The function of this system meets thefunctional requirements of acquisition station.
