摘要许多企业中，尤其在煤矿中的煤炭传输，皮带传输至关重要，如若在斜巷煤炭运输过程中皮带传输这一环节有较大问题时，那么将会造成生产线停产甚至有可能直接造成不可估量的损失。因此，我们会对皮带传输进行集中监控与控制来确保运输中方便可靠。本文采取简单方便的PLC编程语言为核心来进行系统的设计，在硬件电路设计中，完成PLC选型和相关外部电器的选择，同时进行有关的硬件连接图的参考设计，给出相关的要求，使得硬件符合并且能够达到我们所预期的效果；软件设计情况下，我们画出相应的有关的程序流程图。我们将两者结合，使得我们所设计的该系统更加的稳定、可操作、更实用，使得它能够符合我们最初的展望和设计的目标。75153

Integrated Protection System Of Inclined Roadway Based On PLC

Abstract Many enterprises, especially in coal mine in the coal transmission, crucial for belt transmission, if in inclined roadway in coal transportation belt transmission this link is a big problem, so will cause production line shutdown even may directly cause immeasurable loss。 Therefore, in order to ensure the transportation convenient, safe and reliable。 We're going to centralized monitoring and control of belt transmission, this paper adopts simple and convenient PLC ladder diagram programming language on the belt conveyor control system design。 In the hardware circuit design, complete selection of PLC selection and relevant external appliances。 At the same time the hardware connection map of the reference design, presented the relevant requirements, which makes hardware with and can achieve the effect we expected; software design, we draw relevant program flow chart。 We combine the two, which makes the system more stable, more operational and more practical, so that it can meet our initial expectations and design goals。
