便携式数据采集与处理系统的研究

Research on Data Acquisition and Signal Processing System

研究 了一种以笔记本型通用微机为核心,并通过其打印机并行口与外部硬件电路进行通信而构成的便携式信号数据采集与处理系统。介绍了硬件电路的组成和工作原理以及系统软件构成,给出了一生产现场封闭母线温升测试应用实例。该系统配置不同的传感器,可适合于多种生产现场信号的采集与处理工作,具有携带方便、组成灵活、通用性强、性能价格比高等特点,是生产现场信号数据采集与处理的理想便携式仪器。

A data acquisition and signal processing system composed of printer LPT and external circuit by note computer are introduced in this paper. The composition of circuit, system operation principle and system software are also introduced. One application for detecting wiped-generatrix temperature is applied. This system could supplied to venial by changing the sensor. This system hase the charactors such as easy-carrying,flexable composition, high capability ratio to its price. It is and ideal instrument for operation place.
