摘　　要：该波浪数据采集系统应用重力测波仪作传感器,由IBM—PC/XT微型计算机控制,将模拟信号经过A/D转换器进行波浪数据采集。采集到的数据按设计格式存入软盘,以便用处理程序进行统计和谱分析。本系统的数据采集程序在1987年9—11月西太平洋热带海域考察中得到应用,取得了较好的效果。By applying a gravity wave-measuring device as its sensor and controlled by an IBM-PC/XT micro-processor, the simulated signals coming from the sensor pass an A/D converter to collect wave data in the Wave Data Acquisition System. According to the designed requirements, the collected data are stored into a disc. By using processing programs, statistic values of wave data and spectral analyses can be acquired from the stored raw data. Data acquisition of the present system is completed through software, which has been applied in the West Pacific Tropical Expedition,and has proved satisfactory results.
