Description

Maintenance System for Passenger Transfer Apparatus The present invention relates to a maintenance system for a passenger transport device. Generally, various types of high-rise buildings constructed for residential, office, or commercial purposes are equipped with elevator systems to facilitate smooth inter-floor movement for passengers entering and exiting the building. The elevator device comprises an elevator car that moves passengers up and down along a vertical shaft formed inside a building while passengers are on board, a mechanical unit equipped with a motor unit that generates a predetermined power and a hoisting machine that moves the elevator car to a corresponding floor according to the operation of a passenger's button, and an elevator control unit that controls the mechanical unit according to the passenger's button operation to ensure the elevator car operates smoothly and stably. Since breakdowns in these elevator devices are unavoidable during operation, the speed at which repair work is carried out in the event of a breakdown is a crucial factor in elevator maintenance. Generally, when a malfunction is reported in an elevator system, a maintenance worker is dispatched to the machine room to connect a serial cable to the control panel and check the generated error code. The worker then analyzes the error code to identify the cause of the malfunction and proceeds with the repair work. In this case, since the error code can only be checked and analyzed after the maintenance worker is dispatched to the site, the cause of the failure cannot be identified in advance, and consequently, necessary parts or equipment according to the cause of the failure cannot be prepared during the dispatch process. Therefore, since additional parts or equipment required for the repair work must be prepared after the site is dispatched and the site is verified, there are problems such as the repair work procedure being cumbersome and the repair work taking a long time.
