Design of health condition monitoring system of mine hoisting equipment

In view of problem that health condition monitoring system of existing mine hoist equipment uses a single signal for condition monitoring which easily leads to misjudgment, health condition monitoring system of mine hoisting equipment based on signal fusion was designed. The system collects spindle torque signal, bearing vibration signal and wire rope tension signal during operation of mine hoisting equipment respectively. The signal fusion method of decision level was used to calculate and fuse in host computer, and fusion judgment result was displayed. The test results show that the system can effectively monitor health condition of mine hoisting equipment.
