WAITING-TIME DISPLAY CONTROL METHOD AND WAITING-TIME DISPLAY CONTROL METHOD OF SKY PARKING FACILITY

摘要

PURPOSE: To display a waiting time more accurately by comparing an arithmetic waiting time up to the completion of subsequent operation and the waiting time of a waiting-time display section and correcting a reference clock every time operation in one process is completed. ;CONSTITUTION: A control section 13 has a waiting-time arithmetic section 14 arithmetically operating a waiting time until a called pallet reaches an entering and leaving port, a waiting- time subtracting section 16 subtracting the waiting time of a waiting-time display section 11 on the basis of the clock signal of a clock generating section 15, a reference clock setting section 17 for changing clock-period setting, and a comparison section 18 transmitting a clock setting signal over the reference clock setting section 17 by the result of the comparison of the waiting time of the waiting-time display section 11 and an arithmetic waiting time arithmetically operated by the waiting-time arithmetic section 14. The time until the called pallet reaches is arithmetically operated and compared with the current waiting time of the waiting-time display section every time operation in one process is completed, the reference clock is set at a value shorter or longer than one sec in response to the waiting time longer or shorter than the arithmetically operated time, and set in one sec when both equalizes, a waiting-time subtracting process and a reference-clock correction process are repeated until the called pallet reaches, and the waiting time of the waiting-time display section is subtracted successively.;COPYRIGHT: (C)1996,JPO
