文档介绍
购买后包含有 CAD 图纸和论文,咨询 Q401339828 1 车运原煤自动采样系统设计摘要论文阐述了可编程控制器 PLC 在车运原煤自动采样系统中的应用。主要介绍了车运原煤自动采样的 PLC 控制系统总体方案设计,设计出了硬件控制电路、软件程序梯形图及指令表,并给出了系统组成框图和程序流程图。我设计的是对汽车所运原煤进行采样的自动小车控制系统,实现小车的横向、大车的纵向移动以及采样螺旋探头的上升、下降过程。系统采用可编程控制器控制。采样工作过程如下: 当载运车辆到达采样点时,人工启动采样系统,采样小车先横向运行指定时间后停止,然后大车进行纵向运行,到指定位置时停止,螺旋采样筒旋转,采样头下降并旋转进入汽车煤层,到达一定深度后稍做停留,将车载原煤载入采样筒上方的采样斗中;然后采样头上升,大车小车后退回原位,采样头料门打开,煤样流入料斗,取样完成。入厂原煤采制样装置是洗煤厂入厂原煤质量分析中的重要设备。利用可编程序控制器,实现对入厂原煤采制样装置的自动控制,不仅简化了操作,而且提高了系统的可靠性。关键词∶可编程控制器; 采样系统;自动控制购买后包含有 CAD 图纸和论文,咨询 Q401339828 2 Abstract The thesis elaborated the programmable controller PLC in car carry automatic sampling system of raw coal of application. The thesis mainly introduced the total project design of PLC control system that the car luck raw coal automatically sample, design the hardware control electric circuit, software procedure trapezoid chart And the instruction gage, and give the position block diagram and the procedure flow chart. What I design is an automatic and small car control system that samples to the autocar raw coal progress carry, carry out the small car of transversal and big car travel and sample the rising that screw stretch forward and descend the process lengthways. The system adopts the programmable controller control. Sampled the process of operate as follows: When transport the vehicle to arrive the sampling spot, the artificial start sampling system, sample the small car to traverse the running first to stop after specify time, then the big car progress circulates lengthways, while arriving to specify the place stop, the screw sampling tube revolution, sample the prinipal to descend and revolve into the coal seam, coalbed of autocar , make to stop over slightly after arriving the certain depth, carry car the sampling bucket that the raw coal loads in to sample on the above of the tube. Then sample the rising of prinipal, the small car of big car recoil to return to home position, sampling the prinipal to anticipate the door to open, the coal sample flows
