[Abstract]:The development and utilization of marine resources, marine energy, ocean and global environment, climate change, marine environment and earth ecology are the key to human being's survival and development, and to expand the living space. The most feasible way to make the most of the earth's only rich treasure. The exploitation of the ocean requires a wide range of accurate and reliable data of the marine environment, as well as seabed exploration, underwater construction and other tasks. This will require a range of ocean development technologies, including ocean remote sensing, deep-sea exploration, ocean navigation and so on. In recent years, seabed boundary layer in situ monitoring technology has been attached great importance and rapid development. The seabed boundary layer is a complex region with physical and chemical interactions. The environmental data include PH value, dissolved oxygen, temperature, conductivity, flow rate, carbon dioxide, methane content and pressure. Submarine in-situ monitoring technology is a kind of underwater observation technology which integrates various marine equipment and electromechanical technology and can be used to continuously monitor the variation of many physical and chemical parameters in the seabed boundary layer. However, more accurate and detailed seabed boundary layer data can be obtained by collecting the microsection data on the seabed. The research and development of in situ monitoring technology of deep seabed boundary layer is of great significance for promoting the innovation and progress of deep sea scientific research and exploration and development of seabed resources. The system takes Atmel Company AT91SAM9263 as the control core, MSP430 single chip microcomputer as the power control module core, based on the Linux2.6 software platform, adopts double ARM redundant control and data storage design, integrates the deep-sea sensor, step motor and other equipment. The system works at three different heights through the stepper motor control sensor frame, thus realizing real-time, automatic and stable micro-profile data acquisition and control management functions. This paper first introduces the development of deep seabed boundary layer monitoring technology at home and abroad, explains the importance and urgency of developing seabed monitoring technology in China, and puts forward the basic design framework of seabed in situ monitoring system. Secondly, the hardware and software components of the submarine in situ monitoring system are discussed in detail. The hardware part introduces the composition of the hardware circuit of the embedded data acquisition system, the composition of the power supply control system circuit, the various performance parameters and operation methods and commands of the deep-sea sensor, and gives the schematic diagram and the physical diagram of the key circuit. The software part introduces the construction of embedded Linux software platform, including boot program U-boot transplantation, kernel Linux2.6.30 compilation and migration. Then the key part of the application program of the microprofile data acquisition system is introduced in detail. The application program is written in embedded C language and multithread programming is adopted to improve the running efficiency of the program. The program is mainly divided into 3 threads. The main thread is mainly responsible for the control of the whole system, including the communication between the master and slave ARM boards, the control of the power supply of the equipment and the monitoring of the running state of the system by sending instructions to the single chip microcomputer. The data acquisition thread is mainly responsible for controlling the deep-sea sensors for data acquisition, receiving and storing the data sent by the sensor into the SD card on the ARM board. The data upload thread is mainly responsible for the communication between the system and PC, and uploads the collected data. Then, the physical diagram of the monitoring system of the seabed boundary layer in situ microsection is given, and the experimental debugging diagram is given. Finally, the work of the paper is summarized and prospected.
