Mine main fan automatic monitoring system

System introduction
The main mine fan automatic monitoring system adopts bus industrial control system, which integrates advanced technologies such as industrial computer, PLC, intelligent data acquisition, calculation and control, graphic display, image monitoring and network communication.It has the functions of graphic display, centralized display of all kinds of information data, automatic recording of historical data, automatic generation of data report, abnormal alarm and protection shutdown, information networking, printing and so on. It is a set of comprehensive, high reliability, strong universality, good open performance monitoring system.The system has the advantages of high reliability, fast processing speed, high monitoring accuracy, convenient operation and low maintenance cost.
Main Fan Automatic Monitoring System for Coal Mine

System Functions  
  • 1. Centralized control function.Realize the system interlock, start, stop control, protection, ventilator working state online monitoring and data communication and other functions.At the same time, in order to ensure the safe operation of the system when PLC exits or fails, the system has complete manual control and alarm instruments such as motor, fan bearing and motor stator temperature.
  • 2. Conduct online monitoring of fan working status. Collection and display various technological parameters of the equipment operation ventilation room, electrical parameters, electrical equipment running status. Monitoring parameters include inlet static pressure, air volume, gas concentration, fan bearing temperature, motor bearing temperature, motor winding temperature, fan vibration, motor power, current, voltage and power factor. Fan gate switch state, brake switch state, fan main motor start and stop signal and positive and negative turn signal, high voltage cabinet circuit breaker closing and breaking position, spring mechanism energy storage state, ground switch and experimental position, fault alarm, accident trip, abnormal protection device and other signals. Real-time display of fan operating point and efficiency.
  • 3. It can monitor data in real time and display them in dynamic graphics and figures. It can draw characteristic curve of fan performance and output it through printer.
  • 4. Storage and query of various monitoring data. The system saves the data of 365 days from the day, in which the average value of one hour is stored for every hour, and records the average value of all kinds of monitoring data and the trend chart of various parameters of 24 hours a day.
  • 5. Display, accident alarm and recall functions of each working condition can be realized. The operating point of the fan can be shown on the performance curve of the fan. When the fan runs abnormally, the system can give alarm prompt on all relevant interfaces, and record various parameters, dates and times within one hour from the current moment for later analysis.
  • 6. High voltage electric control cabinet can be overvoltage, undervoltage, overcurrent, overload, leakage monitoring, alarm and reverse control.
  • 7. The system has the function of fault self-diagnosis, and analyzes and judges the fault. Printing operation report (shift, day, month, year) and alarm and fault real-time report.
  • 8. Network with the mine dispatch room: transmit the operation status of each equipment in the ventilation room to the mine dispatch center in real time through high-speed industrial Ethernet.
  • 9. Double monitoring is adopted for the bearing at both ends of the motor, the motor stator (three-phase) and the bearing temperature at both ends of the fan.
System characteristics
  • 1. The system can quickly and accurately monitor the operating parameters of the equipment, including important parameters such as temperature, pressure, flow, voltage, current, power, electric quantity, etc. The system can quickly analyze and process the operating monitoring parameters, and timely alarm and protection actions when abnormal conditions are found, so as to prevent major safety accidents.
  • 2. Convenient maintenance and low operating cost.The system is convenient to expand, and can increase or decrease nodes at any time according to the needs to meet the enterprise's all-round needs.
  • 3. The application of computer monitoring system realizes remote data monitoring, control monitoring and other functions, and meets the working conditions of on-site unmanned duty.
  • 4. The monitoring system can connect the site with local area network of the mine through data transmission network, so as to control equipment and browse data from afar, improve the monitoring efficiency, meet the requirements of information management of the whole mine and even the whole world, and ensure the timely deployment of emergency plans in case of failure of the ventilation system.
  • 5. The system adopts industrial-grade computer and modular intelligent data acquisition device to meet the long-term stable and reliable uninterrupted operation in harsh environment, and a set of system can monitor multiple devices at the same time.
  • 6. The system has remote control function. The fan can be started/stopped manually/automatically on the remote computer.
  • 7. Display the running state of the equipment with dynamic graphics, which is intuitive and easy to watch.
  • 8.With digital display, analog instrument, trend curve display equipment operation data, report forms and so on a variety of forms, and automatically deposited in the database for long-term preservation, can consult at any time, guarantee the authenticity, validity of data, reduce the impact of human factors, is conducive to help formulate perfect economic operation plan and find the problems in time, nip in the bud.
