一、数据采集系统的主要组成 图1为系统框图。HP3054A是以微机支持的一种自动数据采集和控制系统,可以自动采集模拟量,数字量和脉冲数;也可以输出模拟量、数字量和模拟量、系统配有为稳态测试用的高精度数字电压表HP 3456 A和为周期性瞬态讯号测试用的高速数字电压表HP3437A.图1中虚线部分为高精度多路测压系统。
First, the main components of data acquisition system Figure 1 for the system block diagram. HP3054A is a computer-based automatic data acquisition and control system that can automatically capture analog, digital and pulse number; can also output analog, digital and analog, the system is equipped with high-precision for steady-state testing The digital voltmeter HP 3456 A and the high-speed digital voltmeter HP3437A for periodic transient signal testing are shown in Figure 1. The dotted line in Figure 1 is a high precision multiway pressure measurement system.
