  • Patent number: 8839914
    Abstract: An elevator system capable of an efficient evacuation using an elevator in case of a fire, and capable of confirming an evacuee remaining status in a case that an evacuation operation using the elevator is discontinued. An evacuation-call response-order setting section sets a priority order of a response to an evacuation special call registered in an evacuation special call registration section, based on fire occurrence information received by a fire situation reception section. A responding floor is selected based on the priority order. The evacuation operation running section controls an operation of the elevator so as to direct a car to the responding floor selected in this manner. In a case that the evacuation operation availability determination section determines that the evacuation operation is not available, the evacuation operation terminating section causes an evacuation special call remaining floor display section to display a remaining evacuation special call registration floor.

  • Patent number: 5196656
    Abstract: An elevator door control apparatus includes an alternating current motor for opening and closing an elevator door. An inverter for converts a DC voltage from a first DC power supply into an AC voltage and supplies it to the motor. A first switching device for connects and disconnects the inverter and the motor, and a second switching device connects and disconnects a second DC power supply and the motor. A detection device detects at least one of an abnormality of the first DC power supply and an abnormality of the motor. A control device, at normal times supplies an AC voltage from the inverter to the motor by means of the first switching device and cuts off a DC voltage from the second DC power supply to the motor by means of the second switching device.

  • Patent number: 5175400
    Abstract: An apparatus for controlling an elevator door based on controlling an electric motor for driving the door with a microcomputer and resetting the microcomputer when the power supply fails has a voltage monitor which detects the power source voltage and a braking circuit forcibly brakes the motor if the power source voltage detected by the voltage monitor is lower than a prescribed voltage. The motor is forcibly braked when the detected power source voltage is between the prescribed voltage and the lower limit of the range of voltages at which the microcomputer can operate.

  • Patent number: 5131506
    Abstract: A system for controlling operation of an elevator car door includes a torque command output device for outputting a torque command for controlling a car door driving motor on the basis of a difference between a speed command commanding the operating speed of the motor and the actual speed of operation of the motor, a door position detector for detecting the position of the car door in terms of the number of pulses in a pulse train produced by an encoder connected to the motor, and a memory for storing torque limit values as a function of the door position. The system also has a controller which reads the torque limit value corresponding to the car door position detected by the door position detector. The controller then compares the read torque limit value with a torque command output from the torque command output device and generates a reversing instruction to be given to the motor upon determining that the torque command is not smaller than the torque limit value.
