CHZ海洋重力仪的多通道数据采集系统设计

Designing a Multichannel Data Acquisition System for CHZ Sea Gravimeter

介绍了24位A/D转换器AD7714的性能、特点,以及它与AT89C2051单片机构成的CHZ海洋重力仪多通道数据采集系统。用VisualBasic6 0实现了视窗界面的各通道测量数据的实时图形显示、存储和打印。

The properties of the AD7714,a 24-bit A/D converter,are simply introduced in this paper.A multichannel data acquisition system of CHZ sea gravimeter is developed using the AD7714 and AT89C2051.Graphic displaying,storing and printing of the data obtained in each channel are implemented by using Visual Basic 6.0.
