Embodiment 1

[0063] A component fatigue degree monitoring method for special machinery, especially for vertical elevators, (see attached figure 1 ), including the following steps:

[0064] Step 1, installing information data collection equipment for each component at the set position of the target equipment;

[0065] Step 2: For the target device, establish a baseline model and a fault model for the overall state of the target device on the cloud server, and perform training and iterative updates respectively;

[0066] Step 3, collecting the operating feature data of the target device and uploading it to the cloud server;

[0067] Step 4, constructing a mechanical state baseline through the baseline model on the operating characteristic data collected by the information data collection equipment on the cloud server;

[0068] Step 5: Use the established mechanical state baseline to compare and carry out fatigue warning, and use the operating characteristic data of the target equipment to ...

Embodiment 2

[0115] This embodiment is basically the same as Embodiment 1, the difference is:

[0116] The target device targeted by this embodiment is an escalator, and the target device monitored by the information data collection device includes a driving device, a step guide rail system, a handrail driving device and a safety protection device. The operation characteristic data of the collected target equipment includes the characteristic data of sound, vibration, current and temperature during the operation of the elevator, as well as the health data, sub-health data and fault data of the elevator, as well as the basic information data of the elevator and the actual operation data of the elevator. For the driving device, the information collected by the information data collection equipment includes data such as the sound, vibration, temperature, etc. of the driving host; the friction between the main drive chain and the driving wheel, and the running sound;

[0117] For the step guid...

Embodiment 3

[0121] This embodiment is basically the same as Embodiment 1, the difference is:

[0122] The target device targeted by this embodiment is a sliding amusement device, and the target device monitored by the information data collection device includes a power lifting device, a transmission device, a vehicle body, and a vehicle connection device. The operation characteristic data of the collected target equipment includes the sound and vibration data during the operation of the scooter, as well as the health data, sub-health data and fault data of the scooter, as well as basic information data and actual operation data. For the power lifting device, the information collected by the information data collection equipment includes the sound of the motor running, vibration information, and the sound of the friction of the reducer and the coupling;

[0123] For the transmission device, the information collected by the information data collection equipment includes the sound of tractio...

Abstract

The invention relates to a component fatigue degree monitoring method for special machinery, which solves problems in the prior art, and is characterized by comprising the following steps of 1, installing information data acquisition equipment for each component at a set part of target equipment; 2, aiming at the target equipment, establishing a baseline model and a fault model aiming at the overall state of the target equipment in a cloud server, and respectively carrying out training and iterative updating; 3, collecting operation characteristic data of the target equipment and uploading the operation characteristic data to the cloud server; 4, performing mechanical state baseline construction on the operation characteristic data acquired by the information data acquisition equipment through a baseline model at the cloud server; and 5, performing comparison by using the constructed mechanical state base line to perform fatigue early warning, and performing calculation by using the operation characteristic data of the target equipment through a fault model to realize early warning before a fault.

Description

technical field [0001] The invention belongs to a method for monitoring equipment, and relates to a method for monitoring the fatigue degree of components used in special machinery. Background technique [0002] Special equipment refers to boilers, pressure vessels, pressure pipes, elevators, hoisting machinery, passenger ropeways, large amusement facilities and special motor vehicles that involve life safety and are relatively dangerous. When special equipment breaks down, it is very easy to cause personal injury to uncertain personnel, and even serious fatal accidents. Therefore, it is necessary to ensure the safe and stable operation of special equipment. For this reason, the state has strict regulations on all kinds of special equipment from the three links of production, use, inspection and testing, and implements full-process supervision and mandatory maintenance. At present, the quality inspection of special equipment in the production stage is relatively complete. ...
