SWITCH SIGNAL DIAGNOSTIC DEVICE FOR VERTICAL TRANSPORTATION DEVICES AND MAINTENANCE PLANNING SYSTEM FOR VERTICAL TRANSPORTATION DEVICES

摘要

Provided is a switch signal diagnostic device for vertical transportation devices which is capable of properly diagnosing deterioration states of switches. This switch signal diagnostic device for vertical transportation devices comprises: a deterioration state sampling unit which measures the states of switches disposed in a vertical transportation device at a deterioration state sampling period that is shorter than an operation control sampling period for use in operation control of the vertical transportation device; a deterioration state diagnostic unit which diagnoses the deterioration states of the switches on the basis of the states of the switches measured by the deterioration state sampling unit; and a deterioration state recording unit which records information related to the deterioration states of the switches diagnosed by the deterioration state diagnostic unit.
