Beacon Lights Wireless Remote Monitoring Terminal System

Pharos is an important aid to navigation for ships. However, its management and maintenance is stereotype with little automation, which brings low security , great manpower and material consumption , low efficiency to ship. This thesis analyzes the demand of pharos management and researches a radio remote terminal for monitoring the pharos on-line using new technology. The project studies can promote the automatic and digital building of sea-route, even to the traffic. It has great theory significance and practical value.The thesis analyzes and constructs the terminal system by separating the monitor task into several modules. The terminal system consists of controller, light check module, position module, radio communication module and power management module, which combine radio communication, Satellite position, computer control, switch power and some other technologies.Model construction and realized method of pharos radio remote monitor terminal system are discussed in the thesis-, feasibility and rationality is analyzed for every module. The system selects micro control unit and programmable logic device as the core of controller, GSM terminal module as communication device, GPS as position equipment, A/D sampling for voltage and current checking, solar battery as power supply, switch DC-DC as power voltage conversion, and so on.GPS position technology has been developed with growing position precision. Many kinds of products were manufactured in some electronic company and the cost and price of these products was increased in ratio by they position precision. Considering the precision and cost of sea-route in our country, GPS OEM board was selected positioning for system in stand-alone model (not DGPS). There is abundant time to processing and optimizing data for GPS receiver because the reactive speed of pharos is onhour level contrast to strict real time. Heighten precision and veracity of GPS position with numerical process and optimization is a critical emphasis to the research.Only regeneration energy can be selected for system power supply for complex and across distribution of rivers, which brings to the system power consumption an outstanding problem, optimization for power consumption was full considering in this thesis.
