文档介绍：摘要
煤矿的运输系统对保证矿井正常生产起着非常重要的作用。为了保证煤矿运输系统可靠安全运行,对带式输送机进行集中监视和控制很必要。本文以新疆哈密煤矿主斜井及地面胶带输送机为背景,设计出了以PLC技术为核心的集中控制系统,提高了运输系统的监测和控制水平。
文中首先介绍了本次设计的背景,然后设计了胶带输送机集中控制系统的结构和应具有的控制功能,参数的检测和故障保护装置,确定了各故障检测传感器的类型及安装位置。在此基础上采用SIEMENS的S7-300系列PLC对系统进行硬件和软件设计,其中包括PLC的模块配置及外部连线,梯形图程序设计。最后提出PLC控制系统的主要干扰源,并设计了抗干扰的措施。

ABSTRACT
Coal transport system to ensure normal production of mine played a very important role. In order to guarantee coal mine safety and reliable operation of the transport system, the belt conveyor to focus on surveillance and control is necessary. In this paper, the Xinjiang Hami Coal Mine inclined conveyor belt and the ground as the background, to design the PLC technology as the core of the centralized control system to improve the transport system of monitoring and control level.
First introduced in the text of this design background, and then design a conveyor belt on the structure and control system should have the control, fault detection and parameters of the protection device, identified the fault detection sensors and installation of the type of position. On this basis the use of SIEMENS S7-300 series PLC to the system hardware and software design, including the PLC module configuration and external connections, ladder program design. Finally, PLC control system the main source of interference and the design of the anti-jamming measures.
Keywords: Belt conveyor; S7-300; Centralized control system
