摘  要
本文介绍了砌块砖成型机PLC自动控制系统的功能、硬件和软件的设计、元器件选择和操作说明。砌块砖成型机是墙砖压制成型的关键设备，是集机、电为一体的现代化高技术设备。我国的压砖机设计制造技术已有了显著进步和提高，为了克服传统的控制手段接线复杂，机械触点多，可靠性低的局限性和缺陷，通过采用可编程序控制器(PLC)予以克服和弥补。PLC是20世纪60年代末随着计算机的发展而发展起来的一种新型工业通用控制器，它可以借助工程技术人员非常熟悉的传统继电器梯形图进行程序设计，以满足不同设备多变的控制要求，使控制系统具有极大的柔性和通用性，因而可以有效地取代传统的继电器控制系统和其它类型的顺序控制器。本设计选用日本三菱公司FX系列PLC进行控制，软件部分，根据硬件接线图以及I/O地址表运用日本三菱公司的FXGP-WIN-C使用STL的编程方式完成系统组态及编程画出梯形图以及对应的语句表，包括自动程序、手动程序、故障报警程序。

Artificial
Brick Shaper PLC Automatic Control System
Abstract: This article introduced the artificial brick shaper PLC automatic control system function, the hardware and the software design, the primary device choice and operation showing. The artificial brick shaper is the essential equipment which the wall brick suppresses takes shape, is the collection machine, the electricity is a body modernization high-tech equipment. Our country brick press design manufacture technology had the remarkable progress and the enhancement, but its control section still used traditional the control method, for example the black-white control system, caused the wiring complex, the mechanical electronic contact many, the reliability was low. These limitations and the flaw may through use the programmable foreword controller (PLC) to overcome and to make up. PLC is the 20th century at the end of 60s one new industry universal controller which develops along with the computer development, it may draw support from the engineers and technicians extremely familiar tradition relay trapezoidal chart to carry on the programming, satisfies the different equipment changeable control request, enable the control system to have the enormous flexibility and the versatility, thus may effectively substitute for traditional the black-white control system and other types sequence controllers. This design selects Japan Mitsubishi Corporation FX series PLC to carry on the control, software are partial, uses STL according to the hardware wiring diagram as well as the I/O address table using Japan Mitsubishi Corporations FXGP-WIN-C the programming way to complete the system configuration and the programming draws the trapezoidal chart as well as the corresponding sentence table, including the automatic procedure, the manual procedure, the breakdown reports to the police the procedure.
