摘要:

以光学浮标为控制对象, 以工作稳定、低功耗为目的, 设计海上工作控制硬件。采用嵌入式PC/104 CPU主板和以单片机为核心多功能板组合, 由PC/104 CPU主板完成采集数据、保存数据、通讯等工作, 多功能板实现计数、I/O控制、A/D转换、定时等功能。单片机结合日历时钟和电源总开关组成二级“看门狗”, 实现了海洋光学浮标控制系统无人值守、全天候、全过程独立工作。

Abstract:

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.

Key words: marine optics, control system, buoy
