Abstract


Ocean with its vast space, abundant resources and special political status is increasingly becoming an important strategic area of ??national attention. Oceanographic key point is that real-time, to learn about the state of the oceans, to the study of marine provide reliable first-hand information. Situ, real-time, continuous detection is to carry out marine research, especially abnormal marine environment efforts to detect key trends and a key marine competitive advantage. In situ chemical sensors based on laser spectroscopy of deep-sea came into being in this trend. In support of the National 863 Program, Ocean University of China to carry out the work on the development of self-contained deep-sea in situ laser Raman spectroscopy system (Deep Ocean Compact Automatic Raman Spectrometer, referred to as DOCARS), as part of the R \u0026 D work, the paper focuses on the system software research and development in order to achieve the purpose of the spectrum detection, image acquisition, working environment monitoring. The DOCARS system consists of hardware and software systems. In this paper, for the specific requirements of the device and a combination of hardware system design and development of software systems, to upgrade the software system and the working conditions in the laboratory tests and sea trials. The hardware system includes a controllable power supply, spectral detection and image acquisition, single-chip control of three subsystems. Controllable by the deep-water battery, power converters, solid state relays and switching power supply power supply subsystem powered optical spectrometer, IPC devices; MSP430 microcontroller to control spectrometer, the IPC and laser working condition and read take the cabin temperature and humidity; controlled by PC104 IPC spectrometer MSP430 microcontroller and camera spectral and image data acquisition, storage, and communications. According to the functional requirements of software written for the system is divided into two parts Water communication control system software and underwater control system software is based on the Visual Studio 2005 integrated development environment, developed using C # language. Through the control of the software system to achieve the DOCARS self-contained cabin environment monitoring, data file transfer and management, the setting of the operating parameters and interactive work. Underwater control system software control by the spectrometer to accomplish the purpose of spectrum signal acquisition; video capture card and camera control access to system photos; on SCM measurement tasks packet write; communication and control systems and development of water software with interactive, data export and post-processing features such as single-chip communication. In the implementation of the deep-sea field trials, prototype of DOCARS experiment must go through a laboratory machine debugging, pressure test deck transfer system, debugging into the water, shallow water test and testing process to ensure the smooth implementation of the deep-sea trials. Accompanied by prototype testing process as one of the key elements of the prototype testing, DOCARS software system testing. Software testing process from the laboratory machine FBI found that the lack of software systems to be improved. Subsequently 40MPa environment software system testing different operating modes. Through the deck into the water before transfer system, to ensure the system into the water. After the trial of the two sea for a long time, the functions of the software system design in the deep-sea field trials has been fully realized, the sea water in the deep-sea environment Raman signal, and took work Photos of the system. Finally, on the basis of summing up the work done, for future work to carry out the prospect, and talking on the further direction.
