The displacement sensor, temperature sensor and oil pressure sensor convert the collected signals into voltage and current signals that can be received by the PLC in real time and transmit them to the PLC for data processing. When the gate relay is activated and the corresponding oil pressure sensor pressure is greater than the set "oil pressure threshold for judging the gate opening", after the set "gate opening timeout detection delay" time. If a gate gap value is always less than the set "gap threshold for judging the gate opening" within the set "gate opening fault filtering time", the system reports a gate opening timeout fault. The fault relay outputs a fault signal. When the detection data exceeds the protection setting value, it outputs a fault signal and issues a voice alarm, prompting maintenance personnel to promptly troubleshoot the alarm fault. By real-time monitoring of the gate opening timeout parameters on the touch screen, fault indication, fault recording and historical curve viewing, the operating status of the hoist can be clearly judged, which greatly ensures the normal operation of the hoist braking system and ensures the safety of mine hoisting. This is the entire working process of the mine hoist gate opening timeout fault detection device.
