  However, in the above-described elevator system, the passengers who are located behind the car are only notified that there are passengers getting off the passengers in the car.

  In other words, if there are many passengers in the car, simply making an announcement may cause the passengers in the back of the car to close before they get out of the car. There was a problem that passengers behind the car could not get off safely.

  In addition, in order to get off the passengers in the rear, the passengers in the front once came out to the landing, urged the passengers from the rear to get off, and then boarded again. It is also supposed to generate extra actions such as opening the door again by operating the door opening button in the car. As a result, when the passenger in front of the vehicle gets off before arriving at the destination floor, the door opening time or the like takes longer than usual, and the travel time to the destination floor becomes longer.

  Therefore, according to the embodiment of the present invention, even when the car is full or nearly full, it is possible to safely prompt passengers to get out of the rear and to extend the door opening time. An object of the present invention is to provide an elevator control device and an elevator system that can prevent an unnecessary operation such as a re-opening operation.

  In order to achieve the above object, an elevator control device according to an embodiment of the present invention includes a plurality of passenger detection devices that are installed in a car and detect passengers, and a door opening and closing control unit that controls opening and closing of a car door. , A storage unit that stores in advance the detection order of detection signals output from the plurality of passenger detection devices, and detection signals from the plurality of passenger detection devices that receive detection signals from the plurality of passenger detection devices. When the determination is made that both are coincident with each other as a result of the comparison of the getting-off determination unit, the getting-off determination unit for comparing the detection order of the detection signal and the detection order of the detection signals stored in the storage unit, A door opening extension command signal is output to the door opening / closing control unit.

Next, after the output signal from the passenger detection device 7 is turned off, the passenger detection device 6 detects the passenger, and the ON signal is output to the getting-off determination unit 9. Thereafter, the output signal from the passenger detection device 6 is turned off. Then, the passenger detection device 5 detects the passenger and an ON signal is output to the getting-off determination unit 9.

  And the getting-off determination part 9 compares the pattern of the output signal from each passenger detection apparatus 5-7 with the output pattern at the time of the passenger's getting off previously memorize | stored in the memory | storage part 10 as mentioned above. As a result of the comparison, when the output pattern stored in the storage unit 10 matches the pattern of the output signal received from each of the passenger detection devices 5 to 7, the getting-off determination unit 9 indicates that the passenger is getting off. Judge.

  When the getting-off determining unit 9 determines that the passenger is getting off, the door opening / closing control command for extending the door opening time of the car door 2 is output to the door opening / closing control unit 11. By this, it is possible to grasp the passenger's disembarkation situation in the car, and when it is getting off, by performing control to extend the door opening time, if the passenger can not get off and is left in the car, It becomes possible to prevent the door from being opened again when the door is closed before getting off.

  On the other hand, when the getting-off determination unit 9 determines that the output pattern of the output signals from the passenger detection devices 5 to 7 is different from the output pattern stored in the storage unit 10, it is determined that the passenger does not get off and the door is opened. Perform normal door opening / closing control without time extension control.

  Therefore, user convenience can be enhanced by performing door opening / closing control according to the passenger's situation.
