Study On Universal Platform Of Ocean Data Collection And Real-time Transmission Based On Iridium Data Communication

Recently, the development of ocean explorations and researches brings higher requirement to the technology of ocean data collection and transmission. Various kinds of marine sensors have come forth, and ocean data transmission is developing towards global coverage, all-weather capability and real-time transmission.By analyzing the present situation and existing problems of the technology of ocean data collection and transmission, a new concept of universal platform of ocean data collection and real-time transmission based on Iridium is raised. This concept aims to improve the universality and practicality of the system of ocean data collection and real-time transmission. The universal platform of ocean data collection and real-time transmission is compatible with different marine sensors, and flexibly shifts among different working mode of the marine sensor, so that different users' demands on data collection and transmission can be fulfilled. Moreover, the concept of universality also lies in the compatibleness with work station of different application services for the MCU controller.In this thesis, the working principle and technical points of the platform is introduced, then the hardware and software design of system controller is emphasized discussing. The design follows two main principles: universality and low power consumption. The part of hardware design includes design for power management circuit, the interface design for MCU controller and marine sensor and the interface design for MCU controller and Iridium modem, etc. As for the software part, a command system which is independent of marine sensor and application services of remote work station is designed.Our design has been applied to the realization of ocean data collection and transmission. The platform performed well on the sea trial and has promising applications.
