AI Technical Summary
In existing technology, when the elevator hall door lock malfunctions, the main board cannot identify the specific floor where the problem occurs, which requires maintenance personnel to check each floor one by one, resulting in low efficiency and reduced elevator utilization.
By connecting the elevator controller with the signal processing device on each floor, a fault search signal is sent. The fault code is displayed by illuminating the call button, and the faulty floor is quickly located. By combining software judgment and hardware control, the call button is kept lit for a long time. With the help of software and hardware switch operation, rapid fault location is achieved.
Quickly identifying the floor where the hall door lock is faulty reduces the workload of maintenance personnel and improves elevator utilization efficiency, especially significantly improving maintenance efficiency in multi-story elevator systems.
