AUTOMATIC CARRIAGE SYSTEM, AUTOMATED CARRIAGE CAR, CONTROL METHOD OF THE AUTOMATED CARRIAGE CAR AND MEDIUM IN WHICH PROGRAM IS RECORDED

摘要

PROBLEM TO BE SOLVED: To protect an automatic carriage car from becoming incapable of running due to the discharging of a secondary battery which is a power supply. SOLUTION: A secondary battery is mounted on an automatic carriage car 12 which is capable of running on a predetermined track as a power supply, The current of the secondary battery 62 is successively detected by an ammeter, and a current signal is transmitted to a host computer with a modem 20. The host computer calculates the residual capacity of the secondary battery based on the current signal. When the residual capacity of the secondary battery is reduced to a value, which is a limiting capacity with which the automatic carriage car 12 is still able to run, the host computer forcibly discontinues the power feed from the secondary battery.
