[0066] There are 4 sets of hydraulic lifting components, each set consists of a first lifting cylinder, a first top moving latch cylinder, a first bottom fixed latch cylinder, and a first horizontal latch cylinder, so there are 16 sets of cylinder stroke sensors.
[0067] The data-driven vertical lift complex monitoring system mainly includes the following four aspects: 1. Mechanical mechanism fault alarm and diagnosis The fault alarm of the mechanical mechanism monitors the vibration frequency of the mechanism, and comprehensively compares the measured vibration data of the mechanism with the fault judgment standard recommended by GB6075 and the monitoring baseline value measured and learned by the system under normal working conditions of the machine equipment. When the vibration amplitude exceeds the alarm standard, a fault alarm signal or an alarm signal is output.
[0068] When the system issues a mechanical mechanism fault alarm, it automatically compares the frequency spectrum of the monitored mechanism vibration signal with the vibration spectrum of the normal operation of the machine and the typical fault spectrum, and outputs the possible cause of the fault.
[0069] 2. Hydraulic system fault alarm and diagnosis Hydraulic system failures are mainly caused by single characteristics of the hydraulic system (such as temperature, pressure, liquid level, etc.). The data measured by the sensor is compared with the design value, and a fault alarm is output when the design limit value is exceeded. System failures are compared with the design indicators of the machine hydraulic system and the overall operation data of the machine through monitoring. When the design value cannot be met, a hydraulic system failure is output.
[0070] 3. Electrical system fault alarm and diagnosis The faults of electrical systems mainly include single characteristics of electrical systems (such as voltage, current, temperature, etc.). The data measured by the sensor is compared with the design value, and a fault alarm is output when the design limit value is exceeded. The faults of electrical systems directly give the cause of the fault and the solution through the data of the sensor.
[0071] 4. Product system fault diagnosis and diagnosis There is also a system failure, which outputs a system failure when the overall operating function or performance of the machine cannot meet the design value through monitoring.
