Abstract:

In order to ensure the reliability and safety of the hydraulic brake system of the mine hoist during operation, an online monitoring device for the hydraulic brake system of the mine hoist based on LabVIEW was designed. LabVIEW and programmable logic controller (PLC) were combined, and the powerful data processing capability of LabVIEW was fully utilized to detect the state parameters of the hydraulic brake system and then analyze and evaluate the device's working condition. A new type of disc spring seat sensor was used to establish the mathematical model of brake positive pressure and strain. By analyzing the fault parameters of the hydraulic station and brake, the fault diagnosis expert system was adopted to diagnose the fault of the hydraulic brake and realize the safety early warning of the hydraulic brake system of the mine hoist. The results show that the online monitoring device of the hydraulic brake system of the mine hoist monitors eight functional modules in real time and uses a hydraulic system fault tree to make real-time fault diagnosis of the system, which is of great significance to ensure the safety and reliability of the mine hoist, extend the service life, improve the mine production efficiency, and reduce maintenance cost.
