个人计算机(PC)为仪器仪表的专家们提供了用于数据采集和控制的廉价的多功能的信号处理工具。在 PC 的早期应用中,其障碍是用户必须开发自己的输入/输出(I/O)接口到传感器和执行机构。而今天许多厂商都有了现成的 I/O 硬件和软件,象终端或其他普通外部设备一样易于安装和使用。
Personal computers (PCs) provide instrumentation experts with inexpensive multi-purpose signal processing tools for data acquisition and control. In the early days of PCs, the obstacle was that users had to develop their own input / output (I / O) interface to sensors and actuators. Many vendors today have off-the-shelf I / O hardware and software that are as easy to install and use as terminals or other common external devices.
