Development Of Central Control Unit Of Marine Dynamic Properties Auto-Monitoring System

"Marine Dynamic Properties Auto-monitoring System"(MDPAMS) is a project of China national 863 programs. It emphasizes the technology of uninterrupted monitoring marine dynamic properties and real-time data transmission. Wave, water level, ocean current, temperature, salinity and some others are to be monitored.As a part of MDPAMS, this thesis focuses on the development of Central Control Unit and Integrated Data Analysis Software. For the system is required to work under water more than 120 days uninterruptedly, low power-consumption becomes vital for the system design. And the methods to lower system power-consumption are provided in both hardware and firmware way.Major work of this dissertationUtilizing MSP430 to design the Central Control Unit, schematic and PCB are accomplished. The serial port communication protocol between Central Control Unit and other modules is designed. And the firmware of Central Control Unit is implemented.Integrated Data Analysis Program based on Excel database is developed to handle the data collected by MDPAMS.Major innovation of this dissertationLowering system power consumption. Methods are provided in both hardware and firmware way.Multi-channel data transmission. A novel protocol is designed for 1-N serial port communication.Large data capacity. Two level FLASH is combined with same data and address bus.Power supply controller. Every module of the system is powered only when needed.
