Design and implementation of pharos information system along Yangtse River
A remote terminal unit of pharos monitor system based on double MCUs is developed to lower its power cost down to 30 mA/4 V. Multi-buffer and multi-class are used to deal with pharos's data. RTCM is transferred through GPRS VPN to improve accuracy of GPS up to 0.9 m. The extended GIS based on S-57 is the platform for users. The system has been running in the Three Gorges along Yangtse River for almost 4 years, and it still works well.
