[0055] Such as figure 1 As shown, a kind of intelligent elevator control system operation failure prediction method of the present invention comprises the following steps:
[0056] Step 01: Define the typical faults of the elevator control system as three types: failure of the elevator traction machine brake, abnormal contactor action, and abnormal shaft switch. The corresponding specific fault types are as follows: figure 2 shown.
[0057] Step 02: Collect and summarize the experience in judging elevator abnormalities or elevator failures accumulated by the technicians of elevator factories and maintenance companies in the process of repairing and maintaining elevators. Analyzing and extracting the abnormal data that can cause the elevator to run in a state of illness from the accumulation of experience, and using the judgment statement and some status polling instructions to realize the code conversion of the necessary factors that constitute its abnormal state.
