PROBLEM TO BE SOLVED: To appropriately correct a learning recording width according to the amount of gain or loss of a timepiece per day. SOLUTION: In a step 1-5, a learning width correcting program 10 calculates the amount (x) of gain or loss (sec/day) per day from a difference dt (sec) between the time t0 to be calibrated and in-device time (t) and the calibration interval dd (day) to the day of the previous calibration, and if in a step 10-6 a learning recording width L (sec) that is the sampling interval of learning shows a value not greater than the amount (x) or gain or loss per day, corrects the learning recording width L in a step 10-7. Using the corrected learning recording width L, a learning means learns time-related data about elevator operation. Therefore, reliability can be enhanced as to learning of the time- related data about elevator operation. |
