The input / output unit 25 of the elevator monitoring device 2 has the same functions as the line control device 32 and the data conversion device 33.

Next, the operation of this embodiment will be described. The MPU 21 of the elevator monitoring device 2 constantly inputs a predetermined control signal from the elevator control device 1 according to the program in the ROM 22 to determine whether or not a failure has occurred. When it is determined that the elevator has a failure, the MPU 21 transmits the failure state as a failure signal from the input / output unit 25 to the center apparatus 3 via the telephone line 4. The transmitted failure signal is received by the line control device 32 of the center device 3 and converted into a digital signal by the data conversion device 33. The processing device 31 takes in the failure signal and extracts the assistance data corresponding to the failure represented by the failure signal from the assistance data storage device 34.
