OPC has been widely applied to coal mine automation control system as an industry standard of communication between the field control substation and PC in the control system. In this paper, through the analysis and design for the transport system of coal mine belt conveyor, communication between the PC and S7-300 PLC is realized by using OPC technology. This paper gives the configuration scheme of OPC Server and develops the OPC Client program. The actual operation shows that the system is stable, reliable of communication and high of data real-time.

Dc Motor Drives

The DC motor has good characteristics of large starting torque and good traction and strong overload capacity, traditional battery motor vehicle often adopts DC motor drives as driving system and uses the series resistance to adjust speed. However, in actual coal production, since motor vehicles are often placed in wet, explosive and dusty environment, the speed control system of motor vehicle has strict proof and moisture requirements, however, the inherent characteristics of the DC motor make it a serious shortcoming in the coal mine production, there is an urgent need to improve the structure to meet today's actual demand for coal mine automated production. This article is in this context, to compare the DC motor speed control system with AC speed control system of the mine car, discussing today's mainstream technical programs of AC speed control system, focus on the analysis of the great differences over performance and economic efficiency of the speed control system of mine motor vehicle after adopting AC speed control system.

This Paper introduced a water storage bucket chain conveyor cleaning machine used in coal mine to clean up the underground water storage, which was mainly made up of the mechanical structure and electrical control system. The mechanical structure consists of walking flatbed, walking drives, chain bucket conveyor. Here focuses on the special structure, the working principle, the work process, the electrical control system, the working condition, the main features and the purpose of the chain bucket convey-cleaning machine. The machine structure was reasonable, the stress was even, the vibration was small, the movement was steady. It can not only adapted to a large water content of coal slime, but also adapted to dry coal slime. It overcomes the low efficiency of spiral roller clearance dealing with the large water content of the slime and the weakness when vacuum suction-type pneumatic conveyor is to clean the dry slime.

The paper deals with the problems of vibration damping and limiting dynamic loads in the electromechanical system of a belt conveyor by means of an adjustable electric drive. A conveying unit is represented as a three-mass ring system, which corresponds to a conveying unit with cinematically closed tape. The development of the structure of the control system for electric drives of belt conveyors with limited dynamic loads in elastic elements will reduce the dynamic loads on the belt and therefore the wear of the belts. Conditions of damping of oscillations in electromechanical system of belt conveyors are defined.

Communication Method

The communication method of the automatically drainage monitoring system for underground coal mine is researched. The advanced PLC control technology and visual InTouch human-machine interface are used to design the control system. The information which is measured by downhole monitoring device can be real-timely transmitted to the ground monitoring stations through the Ethernet optical fiber communication system.The monitoring system can realize on-site manual and automatic control, also can realize remote monitoring and management.This paper mainly describes the implementation process and implementation principle of the data transfer between control unit and remote host computer via Ethernet technology.
