Speed Control System In Coal Flow Direction Based On Coal Amount Detection

In coal mining,coal transport system is composed of multiple transport lap belt system,which involves many high power motor.And in the process of running because few coal feedback not accuracy of speed,at the same time because of using inverse coal flow comprehensive protection control mode in basic raw coal transported in place when the belt is idle,the energy consumption after the accumulation of waste is very big,the other in a number of working face along the trough belt production control,unable to collect real-time coal information,caused the main transportation belt design capacity is big,but because of security risk has been transport cannot achieve large amount,reduce the operation of coal mine economic benefit.Along the coal flow control and speed system,is a kind of in order to be able to realize comprehensive energy-saving solutions.Basic principle is based on the coal flow in position to realize the flow in the coal starting,and based on the size of the coal flow of the whole transportation system in the belt motor speed control,as well as to the production control system provide the production information of coal mining work face,for the entire economic operation of coal mine dispatching data.This topic introduces the flow in the coal,the principle of the control system present situation and research content and significance,and its control logic and the implementation of the system are expounded in detail,including the key equipment of coal amount detection device design points in detail.This paper mainly do the following content.First of all,the present situation of flow in the coal industry control system and experimental Shenhua Guojiawan coal mine system analysis,put forward the problems existing in the current.Second,in view of the flow in the coal control system overall scheme design,and the one of the key equipment of coal amount detection device to a general function and principle analysis.Third,this paper introduces the coal amount detection device of each unit circuit and the interface design,software design and structure design,at the same time,in view of the detection device is simulated experiment and data analysis.Fourth,the system reform of the experimental mine design,through the experiment,the implementation of the control system of mine validation flowdetection device based on coal amount in the control system.For energy saving data before and after the system operation and the economic operation efficiency were analyzed.
