TELEPHONE CALL INSPECTION SYSTEM OF ELEVATOR

PROBLEM TO BE SOLVED: To perform the inspection work of a telephone set installed in a car efficiently without burdening both an operator and a person in charge of maintenance at a remote monitoring center. SOLUTION: A monitoring device 11 on an elevator 10 side and a remote monitoring device 14 on a monitoring center 13 side are connected to each other through a communication line 12. The monitoring device 11 inspects whether a call function of the telephone set 17 installed in the car 16 is normal or not to record the result of the inspection in an inspection result table T1 of a memory 25. The monitoring center 13 accesses the monitoring device 11 at optional timing to inspect whether a communication line between the monitoring device 11 and the monitoring center 13 is normal or not and obtain data of the result of the inspection from the monitoring device 11 at the same time. As a result, the inspection work of the telephone set can be efficiently performed without burdening both the operator and the person in charge of maintenance at the remote monitoring center.
