PURPOSE:To perform elevator group operation control efficiently by outputting an assignment signal of floor call to an elevator other than an assigned one only in case a passenger on a floor makes a call when the assigned elevator is being closed and the passenger fails to enter the assigned elevator. CONSTITUTION:A floor call is inputted at a call button set 3 through a floor call output control unit 4 when a door open command is off, and latching is made with a register request flag at the down edge of gate signal. Then, existence or absence of the register request flag is detected at the down edge of a floor call cancel signal. If a register request flag is set up, a floor call special mask is kept turned on until this routine is started next time. At the moment when the assigned elevator has been closed, this floor call special mask becomes equivalent to the condition where a floor call has been registered, the floor call lamp grows again, and an assignment command is given by a floor call assignment control task to an elevator other than the assigned elevator which is starting. |
