使用离心机模拟现场实验,解决实际工程问题,是一种行之有效的方法。本文介绍离心机数据采集系统。该系统采用主从式两级系统。前端机用单片机实现数据采集;主机使用具有RS-232C 通讯接口的紫金Ⅱ微机完成系统控制、转速测量、数据处理等功能。主、从机间传送数字信号。本章介绍了系统硬件配置,主要电路和软件模块。 Using centrifuge to simulate field experiment and solve practical engineering problems is an effective method. This article describes the centrifuge data acquisition system. The system uses master-slave two-level system. The front end uses the single-chip computer to realize the data acquisition; The host computer uses the Zijin-Ⅱ microcomputer with RS-232C communication interface to complete the functions of system control, speed measurement and data processing. The main, from the machine to send digital signals. This chapter describes the system hardware configuration, major circuits, and software modules.
