精品文档---下载后可任意编辑摘要PLC 是以计算机技术为核心的通用自动控制装置，也可以说它是一种用程序来改变控制功能的计算机。随着微处理器、计算机和通信技术的飞速进展，可编程序控制器 PLC 已在工业控制中得到广泛应用，而且所占比重在迅速的上升。PLC 主要由 CPU 模块、输入模块、输出模块和编程装置组成。它应用于工业混合搅拌设备，使得搅拌过程实现了自动化控制、并且提升了搅拌设备工作的稳定性，为搅拌机械顺利、有序、准确的工作制造了有力的保障。本文所介绍的多种液体混合的 PLC 控制程序可进行单周期或连续工作，具有断电记忆功能，复电后可以继续运行。另外，PLC 还有通信联网功能，再通过组态，可直接对现场监控、更方便工作和管理。关键词：PLC，液位传感器，定时器精品文档---下载后可任意编辑Automatic LiquidMixingDeviceThe of PLCControl System DesignABSTRACTPLC is a general-purpose computer technology as the core of the automatic control device, you can also say that it is an application to change the control computer. With the microprocessor, computer and communications technology, the rapid development of programmable logic controller PLC is widely used in industrial control, and the rapid rise in the proportion. Mainly by the PLC CPU module, input module, output module and the programming device composition. It is used in industrial mixing equipment, making the mixing process of automated control, and work to enhance the stability of the mixing device for mixing machine smooth, orderly, and accurate work to create a strong guarantee. This paper described a variety of liquids can be mixed in the PLC control program for single-cycle or continuous work, with power and memory function, can continue to run after restoration. In addition, PLC communication networking functions as well, and through configuration, can be directly on-site monitoring, work and management more convenient.KEY WORDS:PLC, level sensor, timer目 录前 言...
