摘要：本文介绍了送料小车控制的基本形式。在现代社会中，送料小车的控制在人们的日常生活中和工业生产过程中发挥着重要的作用。随着社会经济的快速发展，早期对送料小车的控制方式已经不能适应现代快节奏的生活和工业生产。如何将PLC应用于送料小车的控制中，并运用其来改善送料小车控制的工作效率使之适应现代化生活和生产的需要，已经成为竟相研究的课题。

　　　本设计中采用日本三菱公司FX2N系列PLC对送料小车进行控制。通过设计启动和停止按钮控制程序的运行和运行。同时，在本设计中引入九个中间继电器分别控制送料小车的各个环节，使送料小车顺序进行，以此提高控制系统的工作效率并使控制系统更加有条理。本设计显示采用三菱FX2N系列PLC 对送料小车进行控制，程序运行可靠且编制简便易行。同时其内部定时器资源丰富，可对送料小车进行精确控制。

Abstract：This paper introduces the basic form of the feeding trolley control. In modern society, the feeding trolley control in people's daily life and industrial production process plays an important role in. With the rapid development of social economy, early on the feeding trolley control methods can not adapt to the fast-paced modern life and industrial production. How to apply PLC to feed the control car, and using it to improve the feeding trolley control efficiency to adapt to modern life and the needs of production, has become a research topic of unexpectedly.

　　　This design uses the Japanese Mitsubishi FX2N series PLC on the feeding trolley control. Through the design of start and stop button control procedures of the operation and operation. At the same time, the design was introduced in nine intermediate relays respectively control the feeding trolley each link, so that the feeding trolley sequentially, so as to improve the control system work efficiency and make the control system more organized. The design of display using the Mitsubishi FX2N series PLC on the feeding trolley control, reliable operation and simple preparation procedure. At the same time its internal timer is rich in resources, can accurately control the feeding trolley.
