| 为了获取海洋连续稳定的气象和水文数据，作者设计了基于Linux的气象水文浮标采集系统，多线程同时测量海面的气象参数（温度、湿度、气压和风速、风向）和海下的水文参数（不同深度的水温和盐度），监控浮标的电压、漏水和开舱状态，测量和监控原始数据自动备份到系统的数据库，通过CDMA/GPRS或卫星与岸站接收系统通信，实现采集数据实时回传、自动备份和数据补发功能。目前已经在近海和远海各布放2套，气象数据和水文数据采集与接收正常。实验结果表明，该方案解决了近海和远海的海洋气象数据和水文数据的同时采集与传输，具有高度的可扩展性，获取的海洋气象和水文数据连续稳定可靠。 |

| Abstract: |
| To obtain the continuous and stable meteorological and hydrological data of the ocean, a meteorological and hydrological buoy acquisition system based on Linux is designed. The meteorological parameters (temperature, humidity, air pressure, wind speed, and wind direction) of the sea surface and the underwater hydrological parameters (water temperature and salinity at different depths) are measured simultaneously through multithreading. The voltage, water leakage, and cabin opening state of the buoy are monitored, and the original data are measured and monitored. An automatic backup of the system database is performed, and communication is ensured with the shore station receiving system through CDMA/GPRS or satellite to realize the functions of real-time data collection, automatic backup, and data reissue. At present, two sets of meteorological and hydrological data have been distributed in offshore and open sea, respectively; the collection and reception of meteorological and hydrological data are normal. Experimental results show that the scheme solves the problem of simultaneous collection and transmission of meteorological and hydrological data in the offshore and open seas. The scheme also has high scalability. Furthermore, the obtained meteorological and hydrological data are continuous, stable, and reliable. |
