Hardware design for control system in optical buoy
光学浮标控制系统硬件设计

A stable and low power electric control system was designed for marine optical buoy. A low power PC104 embed-ded computer was used as the core in the electric control system to implement data acquisition and storage automatically. Real-time data and instructions could be transmitted by CDMA and GPRS wireless network. A customized multi-functional board was used to implement data counting, I/O control, A/D conversion and timing. Two-stage “watch-dog” was built up by a single-chip controller in conjunction with calendar clock and power master switch. The electric control system can ensure the marine optical buoy to work independently for a long time under an unmanned situation.
