Description

  The present invention relates to an elevator system, and more particularly to an elevator system capable of predicting and displaying electric power used by an elevator.

  Generally, an elevator car is a slat type with a counterweight arranged on the opposite side via a rope. If the car rises when the sum of the weight of the car itself and the passenger's weight is heavier than the counterweight on the opposite side, the hoisting machine consumes power. Conversely, when the car rises when the sum of the weight of the car itself and the weight of the passenger is lighter than the counterweight on the opposite side, the hoist generates electric power (regeneration).

  As described above, when power is consumed, power is supplied from the power supply equipment to the motor of the hoisting machine using an inverter or the like. Conversely, when power is generated, the power is supplied from the motor via the inverter converter. Power will be returned to the equipment.

As a conventional technique related to such elevator technology, it is disclosed in Patent Document 1, and the regenerative energy of the elevator car lifting motor is absorbed by the capacitor and stored, and this stored regenerative energy is stored in the motor. It is used as supplementary power for powering power.

The rope 2 is suspended from the hoisting machine 4. That is, the car 1 is disposed on the opposite side to the counterweight 3 via the rope 2, and the car 1 and the counterweight 3 are suspended by the rope 2 using the hoisting machine 4. It is installed with heavy weight.

  As shown in FIG. 1, the hoisting machine 4 is a drive unit that feeds the rope 2 and moves the car 1 up and down in the hoistway, and has an electric motor 7. The facility-side power supply 5 is connected to the inverter converter control device 6 through a power supply line 8.

  As shown in FIG. 1, an inverter converter control device (also referred to as an inverter converter) 6 converts a commercial AC power source into DC power using a rectifier, and converts this DC power into variable voltage AC power for control. The inverter converter control device 6 is connected to an electric motor 7 of the hoisting machine 4 through a connection line 9. Thereby, the electric motor 7 of the hoisting machine 4 is operated by controlling the commercial AC power supplied from the power supply 5 on the equipment side by the inverter converter control device 6.

  A power meter 11 is installed in the power line 8. The wattmeter 11 is a measuring instrument that measures power running power supplied from the power source 5 side to the hoisting machine 4 or regenerative power supplied from the hoisting machine 4 side to the power source 5 side.

  For example, a display device 12 </ b> B is installed inside the car 1, and a display device 12 </ b> C is installed at an arbitrary position in the elevator hall 10, for example, the entrance of the car 1. In the example of FIG. 1, both the display devices 12B and 12C are installed, but either one may be installed.

  The display devices 12B and 12C are connected to the wattmeter 11. As the display devices 12B and 12C, for example, a liquid crystal display device, an organic electroluminescence device, a plasma display device, or the like can be adopted, but the type is not particularly limited. The display devices 12B and 12C can display, for example, the amount of power measured by the wattmeter 11 and whether it is power running power or regenerative power.

  Thus, 1st Embodiment of the elevator system of this invention displays the electric energy of consumption prediction electric power and generation | occurrence | production prediction electric power in the position which uses for passenger M like the elevator 1, for example, an elevator hall. The energy saving effect can be clearly shown to the passenger M. For this reason, 1st Embodiment of the elevator system of this invention can guide a passenger to the action which promotes energy saving.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. Note that, in the second embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description of the same components will be omitted because it is duplicated.

  In the second embodiment of the present invention, the following components are further added to the elevator system in the first embodiment.

  As shown in FIG. 2, the car 1 is provided with a measuring device 21 that measures the load of the passenger M. The measuring device 21 is a load measuring device that measures the load of the passenger M. The measuring device 21 can measure the loading weight of the car 1 by measuring the loading load of the passenger M, and the measurement result of the loading of the car 1 is input to a computing unit 22 as an arithmetic processing unit. Thereby, the computing unit 22 can easily and reliably obtain the loaded weight of the passenger M of the car 1.

  Further, a car call registration button 23 for moving the car 1 to the destination floor is installed in the car 1. The car call registration button 23 is an example of a car call registration device for the passenger M in the car 1 to register a destination floor.

  As shown in FIG. 2, the computing unit 22 stores in advance a distance between floors and a power pattern 24 by loading the car 1. The vertical axis of the power pattern 24 indicates the power, and the horizontal axis indicates the movement distance. The power changes according to the movement distance. In this example of the power pattern 24, a large amount of power is required first, and then the power becomes constant and finally becomes smaller and becomes zero.

  As shown in FIG. 2, when the passenger M presses the car call registration button 23 and designates a floor, the computing unit 22 locates the call registration floor F pushed by the car call registration button 23 and the current car 1. The moving distance 25 from the current floor F1 is calculated. The calculator 22 derives the amount of electric power from the load of the passenger M from the measuring instrument 21 and the electric power pattern 24 in consideration of the movement distance 25. That is, the computing unit 22 calculates the moving distance 25 of the car 1 from the distance between the call registration floor F that is the destination floor and the current floor F1 that is the position of the current car 1, and the car 1 The predicted consumption power amount or the predicted generation energy amount that is predicted to be generated is calculated from the load amount of the vehicle and the travel distance 25 of the car 1.

  The computing unit 22 is connected to the display devices 12B and 12C and numerically displays the predicted consumption power amount or the generated predicted power amount calculated by the computing unit 22 on the passenger M in a digital display, or a plurality By using the display portion, it is possible to divide and display in two or more stages. The display device 12B is installed in the car 1, and the display device 12C is installed at the entrance of the elevator hall on each floor. Thereby, the computing unit 22 uses the display devices 12B and 12C, for example, to subdivide the predicted consumption power amount or the generated predicted power amount into the numerical value of the digital display or a plurality of stages of two or more levels and clearly indicate it to the passenger M. can do.

  Accordingly, at least one of the display devices 12B and 12C can not only display the amount of power from the wattmeter 11 and whether it is powering power or regenerative power, but also can indicate the amount of power consumption or the predicted amount of power generated. It can be displayed or subdivided into two or more stages.

  Thus, 2nd Embodiment of the elevator system of this invention displays the usage-amount of consumption prediction electric power and generation | occurrence | production prediction electric power in the position used for passenger M use like the elevator hall, for example in an elevator hall. The energy saving effect can be clearly shown to the passenger M. For this reason, 2nd Embodiment of the elevator system of this invention can guide a passenger to the action which promotes energy saving.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, the same components as those described in the first embodiment and the second embodiment described above are denoted by the same reference numerals, and the description of the same components is omitted because it is duplicated. To do.

  In 3rd Embodiment of this invention, the component demonstrated below is added with respect to the elevator system in 2nd Embodiment.

  In general, the counterweight 3 as shown in FIG. 3 is set so as to be suspended in weight when the loading of the car 1 is about half of the capacity of the car 1, in the third embodiment, The following description will be made on the assumption that the load 3 and the car 1 are suspended when the load of the car 1 is about half of the capacity of the car 1.

  In FIG. 3, in order to explain the operation of the elevator system, the stop floor 33 of the car 1 in the building, the specific floor 31 above the stop floor 33, and the destination floor 34 above the specific floor 31 are shown. Show.

  When the car 1 shown in FIG. 3 is stopped on a certain stop floor 33 and the passenger M is not on the car 1, a landing call registration device is installed in the elevator hall of a specific floor 31 where the passenger M is located. A case where a call is generated by pressing 32 will be described. The landing call registration device 32 is a registration device for registering the direction in which the passenger M in the elevator hall wants to go.

  In this case, between the abandoned stop floor 33 and the specific floor 31 called, the passenger car M is not on the car 1 and the car 1 is not loaded at all. Is generated. The computing unit 22 computes the first power amount W1 from an operation pattern in which the car 1 is not loaded at all and generates regenerative power. That is, the first electric energy W1 is predicted to be generated when the car 1 is stopped without a call registration and when the car 1 is moving to the stop floor 33 at a position where the car 1 is stopped and a specific destination floor 31. This is the predicted generation power.

  Next, in FIG. 3, a case will be described in which the car 1 moves further upward from a specific floor 31 called. In this case, if the loading of the car 1 is less than half, the loading of the car 1 is smaller than the assumption that the loading capacity of the car 1 is suspended. Therefore, regeneration is performed according to the loading capacity of the car 1. Generate power. However, in general, the landing call registration device 32 is an upward or downward selection button, and the computing unit 22 recognizes to which floor the passenger (user) M who generated the call goes. Can not. In this way, when the passenger M who has generated the call cannot recognize the floor, the calculator 22 generates the call in consideration of the average value derived from the use situation on the first floor or so far. Assume that the target floor 34 is the destination floor. Thereby, the calculator 22 calculates the regenerative electric power when the car 1 moves upward from the specific floor 31 and moves to the destination floor 34 as the second electric energy W2. The total predicted electric power WS generated by a series of elevator operations while the car 1 moves from the specific floor 31 to the destination floor 34 after the passenger M generates a call is the first mentioned above. The predicted electric energy can be obtained by calculating the sum of the electric energy (regenerative electric energy) W1 and the second electric energy (regenerative electric energy) W2.

  By the way, even when the car 1 moves further upward from a specific floor 31 where the car 1 is called, when the car 1 is loaded more than half of the capacity, the car 1 is loaded with the car 1 Since the amount is larger than expected, power is consumed and power consumption is generated. The power consumption at this time is the third power amount W3, which is determined by the loading size of the car 1. At this time, if the third power amount W3 that is the power consumption amount is less than the first power amount W1 that is the regenerative power amount, a series of moves from the stop floor 33 to the destination floor 34 via the specific destination floor 31 The electric power generated by the elevator operation is regenerative power. However, if the third power amount W3, which is the power consumption amount, is greater than the first power amount W1, which is the regenerative power amount, a series of elevator operations that move from the stop floor 33 to the destination floor 34 via the specific destination floor 31 The power due to becomes power consumption.

  On the other hand, in FIG. 3, even when the car 1 is stopped at a stop floor 33 below a specific floor 31 and the elevator hall call of the passenger M on the specific floor 31 is downward. Since the car 1 moves upward from the stop floor 33 to the specific floor 31 at the first call, the first electric energy W1 that is regenerative power is generated. At this time, when the loading of the car 1 is less than half of the capacity in the specific floor 31, the loading of the car 1 is more than the assumption that the loading capacity of the car 1 is suspended. Since the power is small, the power becomes the third power amount W3 which is power consumption. On the contrary, if the loading of the car 1 is more than half of the capacity of the car 1, the loading amount of the car 1 is larger than the assumption that the car 1 is suspended, so the power becomes the second power amount W2 that is regenerative power. Therefore, the total electric energy WS generated by this series of elevator operations is calculated as the sum of the first electric energy W1 and the second electric energy W2, or the sum of the first electric energy W1 and the third electric energy W3. It can be an amount.

  The total predicted electric energy WS generated by the series of elevator operations described above, the first electric energy W1, the second electric energy W2, and the third electric energy W3 are displayed on at least one of the display devices 12B and 12C shown in FIG. can do.

  In the above-described example, the case has been described in which the car 1 is stopped on the stop floor 33 below the specific floor 31 and no passenger M is on the car 1. However, even when the car 1 shown in FIG. 3 is stopped on a floor above a specific floor 31 and no passenger M is on the car 1, The predicted power amount WS can be calculated by calculating whether the regenerative power is generated based on the load amount of the car 1 or the consumed power is consumed. The predicted power amount WS can be displayed on at least one of the display devices 12B and 12C in the same manner.

  In the above description, only a specific floor 31 has been described by taking a specific floor 31 as an example. By installing the display device 12C for every floor, each display device 12C has a predicted power amount WS, 1 electric energy W1, 2nd electric energy W2, and 3rd electric energy W3 can be displayed for every floor. Thereby, the display device 12 </ b> C can give the passenger M information for determining whether to use an elevator or to use another means for movement such as stairs from the viewpoint of energy saving.

  As illustrated in FIG. 3, the display format of the display device 12 </ b> C includes, for example, a dot display or a ○ display that divides the moving direction of the car 1 into an upward direction and a downward direction and expresses the capacity of the car 1. It is possible to arrange the number of partial indicators as many as the number of people or in proportion to the number of people. As illustrated in FIG. 3, the display device 12 </ b> C has a form in which the display color is changed or displayed in order to distinguish and easily recognize the regenerative power display 36 and the power running power display 37 calculated by the calculator 22. Can be different from each other.

  Thereby, the display device 12C clearly indicates whether the moving direction of the car 1 is upward or downward with respect to the passenger M, clearly shows the capacity of the car 1, and the calculated regenerative power 36. The power running power 37 can be clearly indicated so that the passenger M can recognize it accurately.

  Thus, 3rd Embodiment of the elevator system of this invention displays the usage-amount of consumption prediction electric power and generation | occurrence | production prediction electric power in the position which uses for passenger M like the elevator hall, for example, an elevator hall. The energy saving effect can be clearly shown to the passenger M. For this reason, 3rd Embodiment of the elevator system of this invention can guide a passenger to the action which promotes energy saving.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to FIG. Note that in the fourth embodiment, the same components as those described in the third embodiment are denoted by the same reference numerals, and the description of the same components will be omitted because it is redundant.

  As shown in FIG. 4, in the fourth embodiment of the present invention, when the car 1 is moving from the bottom to the top and the car 1 is located below a certain floor 31, The call operation of the passenger M on the floor 31 becomes an effective operation when the passenger (user) M in the elevator hall presses the call registration button 41 in the upward direction. Since the call operation by the downward call registration button 42 is performed after all of the call operations by the upward call registration button 41 are supported, the computing unit 22 simply presses the downward call registration button 42 to Is not calculated.

  Then, as shown in FIG. 4, in the case of the upward call registration button 41, the calculation unit 22 measures the load while on the car 1 with the load measuring device 21, and the calculation unit 22 If the sum of the loading of the car 1 obtained from the vessel 21 and the weight of the passenger M getting in from the elevator hall on the specific floor 31 is less than half of the capacity of the car 1, it is judged as regenerative power. If it is more than half of the capacity, it is judged as powering power. This measuring device 21 is a load measuring device for measuring the load of the car 1.

  For example, the display device 12C in the elevator hall can clearly indicate to the passenger M in the car 1 and the passenger M in the elevator hall whether the regenerative power is generated or the power consumption as power running power. . If the loading of the car 1 is more than half of the capacity, the elevator hall display device 12C can clearly show the power running power to the passenger M in the elevator hall. This display may also be performed on the display device 12B in the car 1.

  Similarly, in FIG. 4, contrary to the case described above, when the car 1 is moving from above to below and the car 1 is located above a certain floor 31, passengers in the elevator hall The call registration button 42 in the downward direction is effective for the M call registration operation. When the call registration button 42 in the downward direction is pressed, the calculator 22 measures the load on the car 1 while being loaded by the load measuring instrument 21, and the calculator 22 is obtained from the measuring instrument 21. If the sum of the load of the car 1 and the weight of the passenger M entering the elevator hall is more than half of the capacity of the car 1, it is judged as regenerative power. Judge.

  For example, the display device 12 </ b> C in the elevator hall can clearly indicate to the passenger M in the elevator hall whether regenerative power is generated or power consumption as power running power. If the loading of the car 1 is less than half of the capacity of the car 1, the elevator hall display device 12C can clearly show the power running power to the passengers. This display may also be performed on the display device 12B in the car 1.

  Thus, in the fourth embodiment of the present invention, the car 1 is moving upward or downward, and before the car 1 passes through the specific floor 31 with respect to the moving direction, the specific floor If 31 passengers want to ride in the same direction as the car 1 moves, the first load from the load measuring device that measures the load on the car 1 and a new boarding on a specific floor 31 are predicted. The sum of the passenger M to be loaded and the second load is calculated, and the predicted power consumption or the predicted generated power that is predicted to be generated can be calculated by the calculation unit 22 as a calculation processing device. The predicted consumption power or the predicted generation power calculated by the calculation unit 22 is displayed on at least one of the display devices 12C and 12B.

  Thereby, 4th Embodiment of the elevator system of this invention displays the usage-amount of consumption prediction electric power and generation | occurrence | production prediction electric power in the position which uses for passenger M like the elevator car or the elevator hall, for example. The energy saving effect can be clearly shown to the passenger M. For this reason, 3rd Embodiment of the elevator system of this invention can guide a passenger to the action which promotes energy saving.

Note that in the fifth embodiment, the same components as those described in the third embodiment and the embodiment in FIG. 4 are denoted by the same reference numerals, and the description of the same components is omitted because it is redundant. To do.

  In the fifth embodiment of the present invention shown in FIG. 5, while the car 1 is moving from the top to the bottom, if the loading of the car 1 is less than half the capacity of the car 1, the power is power running power. Even if it is powering power in this way, the heavier loading of the car 1 can reduce the power used and is effective from the viewpoint of energy saving.

  Thus, from the viewpoint of energy saving, when the car 1 is moving from the top to the bottom, in order to increase the loading of the car 1 more actively, the elevator hall display device 12C The boarding promotion display content 51 for boarding promotion is displayed to the passenger M waiting in the elevator hall regardless of the loading state of the car 1. That is, the passenger of the specific floor 31 moves downward before the car 1 is moving in the downward moving direction and the passenger car 1 passes through the specific floor 31 in the downward moving direction. When it is assumed that the user wants to ride in the direction, the display device 12C displays the boarding promotion display content 51 for prompting the passenger M to board the car 1 regardless of the consumption or generation of power.

  Thereby, 5th Embodiment of the elevator system of this invention can aim at boarding for the passenger M to save energy, and can further lead the passenger M to the action which promotes energy saving.
