Description

  Embodiments described herein relate generally to an elevator control apparatus that performs power saving operation by cutting off power supply to an elevator device.

  In conventional elevators, when there is no elevator user and the specified time has elapsed, the power supply to the elevator motors and brakes is cut off, the lighting in the car is turned off, etc. It is shut down for power saving operation. The return from the power saving operation to the normal operation is when the conditions for canceling the power saving operation, such as receiving an output signal from the hall call registration button provided at the floor landing, are satisfied.

  However, the above-described control method has a problem that the power saving effect is not improved because the power saving operation is canceled as long as the cancellation condition is satisfied, regardless of the user's movement distance between floors.

  First, the configuration of the elevator control device according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

  As shown in FIG. 1, a machine room 100 is provided with a hoist 1, an elevator operation control unit 2 (hereinafter referred to as an operation control unit 2), and a deflecting sheave 3. The car 5 is provided with a load detection device 4 for detecting the load in the car. Although not shown, the load detection device 4 is connected to a car control device 9 to be described later, and can transmit load information to the elevator operation control unit 2 via the car control device 9. The car 5 moves up and down in the hoistway 7 by the hoist 1 via the rope 6.

  A counterweight 8 is provided at the other end of the rope 6 that suspends the car 5. A car door 10 that can be freely opened and closed is provided at the entrance of the car 5, and a hall door 101 that engages with the car door 10 when the car 5 is landed and performs a door opening operation in conjunction with the car door 10 is provided. ing.

  A car control device 9 is provided at the upper part of the car 5, and the car door 10 is opened and closed when the car 5 is landed to allow passengers to get on and off. The car control device 9 is connected to the operation control unit 2 by a tail cord 12 and can communicate therewith. In addition to the door opening / closing operation, the car control device 9 is set to control a car illumination, an air conditioner, and an announcement device (not shown).

  As shown in FIG. 2, the hall 101 is provided with a hall call registration button 13 (a hall call registration unit) in addition to the hall door 11. A signal cable 14 is laid in the hoistway 7, and an operation control unit 2 that controls the operation of the elevator is connected to a landing call registration button 13 that is provided at the landing and performs call registration of the car 5. Call registration information is output to the operation control unit 2. Moreover, the operation control part 2 which controls each to the motor 15 and the brake 16 with which the winding machine 1 is equipped is connected. The operation control unit 2 includes an operation mode determination unit 21 that determines an operation mode.

  In addition, as shown in FIG. 3, the car 5 is provided with a car door 10 and an operation panel 17, and the operation panel 17 displays an in-car indicator 18 for displaying movement information of the car 5, and the user goes to the destination floor. An in-car destination floor registration button 19 (in-car destination floor registration unit) is provided. The in-car indicator 18 and the in-car destination floor registration button 19 are each connected to the car control device 9, and the car control device 9 is connected to the operation control unit 2 through the tail cord 12 as shown in FIG. Car call registration information is communicated.

  Hereinafter, a call that calls the car 5 at the landing is referred to as a landing call, and a call that registers the destination floor of the car 5 within the car 5 is referred to as a car call.

  Next, a procedure for switching from operation in the normal mode to operation in the power saving mode of the operation control unit 2 in the present embodiment will be described with reference to FIG.

  As shown in the flowchart of FIG. 4, when the car 5 is operating in the normal mode (S 1), the car 5 stop time elapses for a predetermined time (S 2), and the load in the car 5 is reduced by the load detection device 4. If the operation mode determination unit 21 determines that it has not been detected (NO in S3) and the output signal from the hall call registration button 13 has not been received (NO in S4), the operation control unit 2 aims to reduce power consumption. Then, the power source of the car control device 9, the motor 15, the brake 16, and the car destination floor registration button 19 is collectively shut off (S5), and the operation mode of the car 5 is switched to the power saving mode (S6).

  However, at this time, the operation control unit 2 and the hall call registration button 13 are set so as not to be cut off.

  On the other hand, after the car 5 stop time has elapsed (S2), when a car load is detected (YES in S3), or when an output signal from the hall call registration button 13 is received (YES in S4), The operation mode determination unit 21 determines that the operation control unit 2 has an elevator user, and the operation control unit 2 continues operation in the normal mode (S1).

  The configuration and operation described above are usually performed as a general power-saving operation. In the present embodiment, in order to further enhance the power saving effect, the power supply restoration to each device that cuts off the power supply is restricted under certain conditions.

  Hereinafter, the return from the power saving mode to the normal mode will be specifically described with reference to FIG.

  In the present embodiment, the operation control unit 2 shown in FIG. 2 uses a hall call registration button on the floor close to the top floor or the bottom floor as a restriction condition for power restoration to each device that cuts off the power supply. Depending on the output signal from 13, the power supply of each device is set not to be restored.

  Here, for example, consider the case of a 10-story building.

  The operation mode determination unit 21 determines whether or not the output signal from the hall call registration button 13 is received during the power saving mode (S7), and determines that the output signal is not received (NO in S7). ), The operation control unit 2 continues the power saving mode. On the other hand, when the output signal from the hall call registration button 13 is received (YES in S7), the operation mode determination unit 21 calls the hall up on the floor close to the top floor or the floor close to the bottom floor. It is determined whether the call is a hall down call on the floor (S8).

  At this time, if the call is a hall-up call on the floor close to the top floor or a hall-down call on the floor close to the bottom floor (YES in S8), the operation control unit 2 continues the power saving mode (S9). ). If it is not a hall up call at the floor close to the top floor or a hall down call at the floor close to the bottom floor (NO in S8), the operation control unit 2 switches to the operation in the normal mode (S10).

  Specifically, in the present embodiment, the second floor from the lowest floor and the top floor is set as the adjacent floor. And, for example, when a user on the second or third floor hall makes a hall-down call with the hall call registration button 13, the lowest floor is the first floor, so there is less movement between floors. Is guessed. In other words, in this case, the operation control unit 2 does not return the power of each device that has been cut off, and continues the power saving mode. In the case of hall-up calls on the 8th and 9th floors near the top floor, the power supply is not restored in the same manner.

  Further, in the above case, by partially shutting off the power of the hall call registration button 13 in the case of a hall up call from the nearest floor on the top floor and a hall down call from the nearest floor on the bottom floor, in the first place, No signal may be output from the hall call registration button 13 to the operation control unit 2.

  In the present embodiment, the movement between floors is restricted by setting the second floor from the top floor and the bottom floor as adjacent floors. However, depending on the level of the building, it is free from the nearest floor to the top floor or the bottom floor. It is good also as what can restrict | limit a movement. For example, in the case of a 50-story building, it is assumed that the operation control unit 2 can be set, such as restricting the movement of the 5th floor adjacent from the top floor or the bottom floor as the adjacent floor.

  As described above, according to the present embodiment, switching from the power saving mode to the normal mode is not performed for a slight movement between floors, and power supply to the elevator equipment is not performed. Power saving effect is improved.

  In this embodiment, the power is not restored for a slight movement between floors. At this time, for the convenience of the user, a hall call registration button 13 as shown in FIG. In addition, a display unit 20 that displays that the operation is restricted may be provided. The display unit 20 is connected to the operation control unit 2. By adopting such a configuration, even if the power supply is not restored, the user is not recognized as a malfunction of the elevator.

  For example, as shown in FIG. 6, the display unit 20 displays “down call registration is not possible” at the second floor hall. For the nearest floor platform on the top floor, “Up call registration is not possible” is displayed.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.

  FIG. 7 is a flowchart showing a procedure for switching the power saving mode according to the second embodiment of the present invention.

  In the first embodiment, the operation of the car 5 is restricted only when the user registers the hall call on the top floor or the nearest floor of the bottom floor, but in the second embodiment, the hall call is restricted. Regardless of whether the registered floor is the uppermost floor or the nearest floor of the lowermost floor, the operation of the car 5 can be restricted and the power saving effect can be enhanced.

  Hereinafter, switching from the normal mode to the power saving mode in the present embodiment will be described using the flowchart of FIG.

  First, the operation of the car 5 is shifted from the normal mode to the power saving mode by the same method as in the first embodiment, and becomes the power saving mode. Thereafter, when the operation mode determination unit 21 determines that the output signal from the landing call registration button 13 has been received (S11), it further determines whether or not the landing call registration is performed on the floor where the car 5 is stopped. (S12). Here, when the operation mode determination unit 21 determines that it is a hall call registration other than the floor where the car 5 is stopped (NO in S12), the determination after step 8 (S8) described above is performed. . And, in the case of landing call registration on the floor where the car 5 is stopped (YES in S12), the operation control unit 2 is a device other than the motor 15 and the brake 16, that is, the car control device 9 and the car destination floor registration button. The power supply for the minimum equipment required for calling the car such as 19 is restored, and the apparatus shifts to the standby mode (S13).

  Here, the standby mode is one of the power saving modes, and indicates a state in which power is supplied to the minimum equipment necessary for calling the car other than the motor 15 and the brake 16.

  For example, when the car 5 is stopped in the power saving mode on the second floor and the user makes a hall-up call using the hall call registration button 13 on the second floor, the operation control unit 2 uses the motor 15 and the brake 16. Perform power recovery for the above devices other than.

  Then, after shifting to the standby mode (S13), when the user who has boarded the car 5 designates the destination floor with the car destination floor registration button 19, the operation mode determination unit 21 outputs from the car destination floor registration button 19 The signal is received (S14), and the operation mode determination unit 21 determines whether or not the destination floor is moving to a floor close to the stop floor of the car 5 (S15). Here, in this embodiment, the upper and lower two floors from the floor where the car 5 is stopped are set as adjacent floors.

  When the operation mode determination unit 21 determines that the designated destination floor is a movement to the adjacent floor of the car 5 stop floor (YES in S15), the operation control unit 2 returns the power of the motor 15 and the brake 16 to each other. Instead, the standby mode is switched to the power saving mode after the predetermined condition is satisfied by the same method as in step 4 (S4) described above (S16).

  Here, a signal may not be output to the operation control unit 2 in the first place by partially shutting off the power source of the car destination floor registration button 19 in the above case.

  On the other hand, when the operation mode determination unit 21 determines that the vehicle is not moving to the adjacent floor based on a signal from the car destination floor registration button 19 (NO in S15), the operation control unit 2 turns on the power of the motor 15 and the brake 16. Return to normal mode (S17) and move to the destination floor (S18).

  Specifically, in this embodiment, when a user who has boarded the car 5 on the second floor wishes to move to the third floor by using the destination floor registration button 19 in the car, the operation mode determination is performed. The unit 21 determines that the movement is to the adjacent floor, and the operation control unit 2 switches to the power saving mode without returning the power of the motor 15 and the brake 16. In addition, when a user who has boarded the car 5 on the second floor desires to move to the sixth floor by using the destination floor registration button 19 in the car, the operation control unit 2 sets the motor 15 and the brake. The power source of 16 is restored and the car 5 is moved to the sixth floor which is the destination floor.

  In other words, according to the present embodiment, the in-car destination floor registration button 19 can restrict the inter-floor movement to the floor adjacent to the stop floor of the car 5 and improve the power saving effect.

  In this embodiment, the upper and lower two floors from the stop floor of the car 5 are set as the adjacent floors, and the movement between the floors is restricted. However, the movement of the car 5 from the stop floor is restricted freely depending on the building hierarchy. It is good also as what can be done. For example, in the case of a 50-story building, it is assumed that the operation control unit 2 can be set, for example, by restricting movement from the car 5 stop floor to the upper and lower 5 floors as an adjacent floor.

  In the present embodiment, when switching from the standby mode to the power saving mode, an announcement that the user in the car 5 is switched to the power saving mode without operating to the destination floor so that the user in the car 5 is not recognized as a failure. It is good to do. The announcement may include a display on the car indicator 18.

  Further, in the present embodiment, the inter-floor movement to the floor adjacent to the stop floor of the car 5 is limited. However, the inter-floor movement may be freely restricted by the level of the building. For example, in the case of a 50-story building, it is assumed that the operation control unit 2 can be set, for example, by restricting the movement of the upper and lower 5 floors from the stop floor of the car 5 as the adjacent floor.

  In the present embodiment, when the operation mode determination unit 21 determines that the hall call registration is performed at a place other than the floor where the car 5 is stopped, the mode is shifted to the standby mode. If the registration is a hall-up call at the floor near the top floor or a hall-down call at the floor near the bottom floor, the operation control unit 2 may continue the power saving mode.
