Based on the Online Monitoring and Fault Diagnosis System of the Main Hoist for Mine

According to the reality, an online monitoring and fault diagnosis system of the main hoist for Mine was designed in this article. The system adopts the signal acquisition and processing, fault diagnosis, Web visualization, network real-time database and other related technologies, Real-time monitoring the current, voltage, temperature, speed, vibration and other parameters of the main elevators to Achieve the goals that Increasing efficiency by downsizing, protecting the safe operation of equipment, reducing the maintenance costs. The main hoist shoulders the important task of transportation, which is one of the key equipment in the coal production. However, there are many failures in the main hoist system, they are even hidden and unpredictable. Once the hoist is out of control in operation, hoist speed, paper and other incidents will occurs, thus affecting the normal production of mine, even causing injury or significant economic loss. In order to improve the operation of hoist reliability and resolve the elevator trip, speed control problem, doing research on the mine hoist-line monitoring and fault diagnosis system has great significance. According to Luan ring can Ltd's wang zhuang coal of the actual situation, the paper designs a Web-based mine main hoist online monitoring and fault diagnosis system. The system real-time monitoring the motor, gear box, drum, sheave and other major equipment, sending the system's signals to the industrial machine through data communication technology. Then adopting computer data analysis techniques to record,collect and analyze the key parameters in the process of running and dynamic variation in real time, diagnosing the fault, thus determining the possible site of an accident reason, degree of degration and the corresponding maintenance measures, and then executing remote control.
