Description

  The present invention relates to an elevator control device.

  There is known a multicar elevator in which a plurality of cars are provided in one hoistway, and these cars move up and down in the hoistway (see, for example, Patent Document 1).

  In general, in the event of a fire, except for special elevators such as emergency elevators, the normal elevator control system for ordinary passengers can stop the elevator after it has been transported to the evacuation floor and then use the elevator. Control operation control is performed to prevent the occurrence of secondary disasters. If an elevator is used as a means of transportation in the event of a fire, when the door is suddenly opened to the floor filled with non-combustible gas and oxygen in the cab is sent to the floor, an explosion occurs and a backdraft occurs. Getting passengers to the fire floor can present an unexpected danger to personnel in the car. The multi-car elevator is not allowed to be used as a moving means when a resident evacuates.

  2. Description of the Related Art Conventionally, an elevator operating device has been proposed that can perform rapid control operation during earthquake control operation and fire control operation (see, for example, Patent Document 2). Patent Document 2 discloses that in a one-shaft double-car elevator, after the control operation of the lower car is completed, the lower car is moved to a floor below the evacuation floor, and then the upper car is controlled.

  In addition, a multi-car elevator has been proposed that enables passengers to be efficiently transported to all floors in other cars without stopping the operation of all cars when the car breaks down (for example, Patent Document 3). reference).

Furthermore, operation floor changing means 29 (change means) for outputting a command to the operation control unit 27 is provided so that the car 4 is arranged on a floor below the floor where the fire occurred.

  In the multi-car elevator 1 having such a configuration, the operation control unit 27 accepts and registers calls from the hall call operation panels 23 and the car operation panel 19 at normal times. The operation control unit 27 moves to the floor registered in the car 3 in the upper zone and moves to the floor registered in the car 4 in the lower zone.

  Next, a fire occurs on either floor. When the fire detection signal is input from the fire detector 26 to the fire detection means 28, the fire detection means 28 notifies the operation floor changing means 29 of the fire occurrence floor information. The operation floor changing means 29 places the car 3 on the floor above the fire occurrence floor and the hoisting machine 5 so as to place the car 4 on the floor below the fire occurrence floor with respect to the operation control unit 27. 6 outputs a command signal. When the operation control unit 27 completes the operation of placing the cars 3 and 4 on the upper floor and the lower floor, the operation control unit 27 sets the fire occurrence floor as a service-prohibited floor and uses the hall call operation panel 23 of the fire occurrence floor. Call registration is prohibited, cars 3 and 4 are prohibited from stopping on this fire floor, and doors on the fire floor are prohibited.

  The state of each of the cars 3 and 4 is set to a state in which an operation service is possible for each floor except the floor where the fire occurred. In this state, the evacuees use the cars 3 and 4 as moving means during evacuation.

  FIG. 4 is a diagram for explaining an evacuation method based on operation control by the elevator control device according to the present embodiment. FIG. 4A is a diagram showing the car positions of the cars 3 and 4 before the occurrence of a fire. The control panel 15 commands the car 3 and 4 to move one by one above and below the fire occurrence floor 30 as a boundary. A zone to be serviced is generated by the control panel 15 starting from the fire occurrence floor 30. The generated new zone information is read by the operation control unit 27.

  FIG. 4B is a diagram showing the car positions of the cars 3 and 4 after being divided into zones after the occurrence of a fire. The car 3 descends from the upper zone and stops once on the floor immediately before the fire occurrence floor 30 to drop the passenger. The control panel 15 commands the in-car operation panel 19, and the in-car operation panel 19 “Get off. Use the emergency stairs to go down to the second floor. Change to the waiting car there.” Voice announcement and display. Thereby, the passenger in the car 3 can perceive the situation and is guided to the lower floor where the car 4 is stopped without hesitation. The control panel 15 notifies the hall call operation panel 23 of each floor hall including the fire occurrence floor using the voice announcement and the display to inform the position of the evacuation floor. The control panel 15 may notify the building management or security terminal or the disaster prevention terminal and link the in-house broadcast so as to notify the evacuation.

  When a person evacuates to the hall on the second floor under the emergency stairs 31 which is an evacuation route at the time of fire, the car 4 called by the control panel 15 is waiting there. This floor is the transfer floor. While the car 4 is waiting on this floor, the car control device 18 monitors the output of the load detection device 20, and the door is not closed until the load of the car room increases. When an evacuee who has evacuated from the car 3 in the upper zone enters the car 4 located on the lower side, the control panel 15 instructs the car 4 to open the door, reads out the direction and floor to be moved from the storage unit 25, Move the car 4 to the first floor, the evacuation floor. Passengers who transfer from car 3 to car 4 get off at the evacuation floor and evacuate from the hall on the evacuation floor to the outside of the building.

  In addition, the control panel 15 limits the emergency staircase 31 so that it does not respond to hall calls from the floors of the lower zone and the upper zone to the car 4 while the person is moving. The car 4 is stopped only by limiting the response to the pressing operation operated by the door opening button of the car operation panel 19 in the car 4.

  That is, when the fire detector 26 installed on each floor detects the occurrence of a fire and the fire occurrence floor, the control panel 15 determines the upper car 3 zone and the lower car 4 zone as the fire occurrence floor 30. Is divided at the border.

  Therefore, according to this elevator control apparatus, even when a fire occurs, the elevator can be secured as a moving means during evacuation. When an elevator is used for evacuation in the event of a fire, all the people in the building can be evacuated to the evacuation floor efficiently.

  The floor above the second floor of the fire occurrence floor 30 is the lower floor of the upper zone, or the floor below the second floor of the fire occurrence floor 30 is the uppermost floor of the lower zone, so that the floor is appropriately changed. Also good.

  The multi-car elevator 1 can be used both during normal times and when a fire breaks out.

The configuration of the elevator system including the elevator control device according to the present embodiment is the same as the example of the first embodiment.

  With such a configuration, when the floor where the fire is detected is the lowermost floor or the uppermost floor, the operation control unit 27 brings the cars 3 and 4 close to each other. The receiving plate 22 attached to the lower beam of the upper car 3 contacts the shock absorber 21 attached to the upper beam of the lower car 4. The car entrances of the upper and lower cars 3 and 4 face the entrances and exits that are located separately for the upper and lower floors. For example, when a fire occurs on the lower terminal floor, the cars 3 and 4 travel together downward and transport the evacuee to another upper evacuation floor. When a fire breaks out on the upper terminal floor, the cars 3 and 4 travel together upward and transport the evacuee to another evacuation floor below.

  The car arrangement of the multi-car elevator 1 is the same as the car arrangement when the multi-deck elevator having a structure in which two or more cars are connected to each other on the upper and lower sides keeps the distance between the cars as much as the first floor. . After the cars 3 and 4 are arranged like an elevator with a multiple deck structure, the control panel 15 performs an elevator operation with the floor other than the fire occurrence floor 30 as a service floor.

  Therefore, according to the elevator control device of this embodiment of the present invention, when a fire occurs on the terminal floor, one of the cars 3, 4 cannot be placed on the non-fire floor. However, it is possible to effectively evacuate using an elevator car having a multi-car configuration having a plurality of cars 3 and 4. Even in a situation where a fire has occurred on the top floor or the bottom floor of the building where the multi-car elevator 1 is installed, the multi-car elevator 1 can be used to evacuate and rescue.
