前面几讲我们已经系统介绍了数据采集系统的设计方法。实际上,“数据采集”既是实现测量与控制的技术工具,又是发展计算技术与通讯技术不可缺少的手段。现代科学技术的发展已在速度、分辨率、精度、接口能力、抗干扰能力以及系统结构方面对数据采集系统的设计提出了越来越高的要求。微电子技术的一系列成就以及微型计算机的广泛应用,不仅为数
In front of a few we have systematically introduced the design of data acquisition system. In fact, “data acquisition” is not only a technical tool for measurement and control, but also an indispensable means for developing computing technology and communication technology. The development of modern science and technology has set higher and higher requirements on the design of data acquisition system in terms of speed, resolution, accuracy, interface capability, anti-interference ability and system structure. A series of achievements of microelectronics technology and the widespread use of microcomputers, not only in numbers
