Present situation and developing trend of coal mine automation and communication technology

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.

Wideband Wireless Communication

Ultra-wideband wireless communication technology is brought, in the coal mine communications in this paper in order to raising the safe level of communication in coal mine. Ultra-wideband wireless communication is a system which is transmitted by the extremely narrow pulse transmission. An avalanche transistor is the core of extremely narrow pulse circuit. Narrow pulse wave form can be simulated by multisim software. Acquiring the results of simulation is the extremely narrow pulse whose pulse amplitude ranging from 10 v to dozens v and pulse width is about 3 seconds. In addition to this circuit carries on the theoretical analysis, the results is quite consistent with the simulation value in this paper.
