[Abstract]:With the development of microelectronic technology, communication technology and industrial Ethernet technology and the deepening of national attention to coal mine safety production, coal mine equipment is intelligent. As the core part of the whole coal mine safety production guarantee system, the coal mine electric power monitoring system directly covers the power supply of the underground mining equipment and the safety production guarantee equipment. It is necessary to ensure the stability and reliability of the underground power supply network in coal mines and to ensure the safety and security of the underground power system. Therefore, the use of more modern and intelligent equipment to reduce the power supply accidents caused by human factors, It is of great practical significance to establish a perfect and reliable network of coal mine electric power monitoring system to strengthen the management of coal mine power equipment production, to provide stable and reliable power supply and to ensure the safety and reliability of coal mine production. In order to achieve this goal, this paper consulted a large number of related papers of electric power monitoring system, analyzed and summarized the domestic and foreign development status and shortcomings, through the actual investigation of coal mining enterprises, This paper puts forward the design scheme of coal mine electric power monitoring system based on FPGA ARM, and emphatically discusses the electric power monitoring system composed of programmable logic device and embedded microprocessor. The system design mainly includes underground communication sub-station and high voltage integrated safeguard switch signal acquisition system. As an important part of the information system of coal mine, the communication sub-station should be able to transmit a large amount of information in real time to ensure the high efficiency of the downhole data transmission. Reliability and stability. The high voltage integrated safeguard switch signal acquisition system adopts the double CPU structure of FPGA ARM, the system carries on the logic control through the FPGA, completes 10 channels AD signal synchronous acquisition, realizes the current, The voltage signal monitoring .arm microprocessor mainly processes and communicates the collected data. It can switch tasks by embedding the operating system and the network communication protocol stack. The paper has completed the design of the communication sub-station and the signal acquisition system of HV HV switch. The system makes full use of the advantages of programmable logic device and ARM microprocessor to realize the data measurement of underground power network in coal mine. Control and monitoring. Test results show that the system meets the design requirements.
