Description

  The present invention relates to an elevator group management control device that performs group management control of operations of a plurality of elevators.

  Conventionally, large-scale facilities and high-rise buildings have been equipped with multiple elevators, and the operation of these elevators is managed by group management so that each elevator car can be operated efficiently according to calls from passengers using the elevators. Therefore, the waiting time of passengers is reduced and energy saving is realized.

  For example, as one of the prior arts of this type, there are a plurality of cars that serve a plurality of floors, a hall call device that is provided on each floor and uses each car, and for driving each car up and down There is known an elevator control system that is provided in a plurality of elevators including an electric motor provided for each car and performs group management control of the operation of these elevators (see Patent Document 1).

  Specifically, this prior art elevator control system is provided in common to a plurality of elevators, and includes a control device that drives the motor of one selected elevator. This control device is the earliest registered hall. Means for selecting the elevator having the call as the driving elevator. The control means includes a set of power converters set to be greater than the required power of one elevator and smaller than the total required power of all elevators, supplying power only to the selected drive motor of the elevator, We are going to drive sequentially. Thereby, the control apparatus for the number of elevators becomes unnecessary, and the apparatus is simplified.

  As another conventional technique, a power consumption prediction calculation device that predicts and calculates power consumption required for driving a plurality of elevators is compared with a predicted value of predicted power consumption and a preset allowable value. When the predicted value exceeds the allowable value, the elevator group management is provided with a control command generator that issues a command to control at least one of the plurality of elevators to an operating state different from the predicted operating state. A control device has also been proposed (see, for example, Patent Document 2).

  Generally, the power consumption until the elevator car starts running and stops has a steep peak during acceleration, and the power consumption during steady running is smaller than that during acceleration. Therefore, the elevator group management control device of the prior art avoids the simultaneous acceleration of a plurality of elevators or reduces the operation speed of the car by controlling the start timing of the elevator by the control command generator. As a result, the peak of power consumption does not occur.

  Here, in a building where a plurality of elevators are installed, in addition to the elevator, air conditioning equipment and lighting equipment, and power supply means for supplying power to these equipment including the elevator, are provided. Power is distributed. Also, in times when there are few people working in the building, such as work hours and lunch hours, the number of people in the building will increase and decrease, and the elevator usage rate will increase. Therefore, it is more comfortable for people entering and leaving the building to distribute power to each elevator and operate multiple cars at the same time than to distribute power to the air conditioning and lighting equipment during this time period. It is easy to lead to energy saving of the whole building.

Japanese Patent No. 3488852 JP-A-57-90368

  The prior art elevator control system disclosed in Patent Document 1 is used only for an elevator motor having a hall call that is registered earliest by a single control device that drives and controls a plurality of motors corresponding to a plurality of cars. Since the elevator is sequentially operated by supplying power, the plurality of elevators cannot be operated at the same time even if a plurality of hall calls are registered. For example, even if there is a surplus in the amount of power in a building and sufficient power can be supplied to a plurality of elevators, the elevator control system of the prior art can only operate one elevator at a time. The problem is that power cannot be used effectively.

  In the elevator group management control device of the prior art disclosed in Patent Document 2, the control command generation device is configured so that the power consumption predicted and calculated by the power consumption prediction calculation device does not exceed a preset allowable value. By controlling the operation, it is possible to operate a plurality of elevators simultaneously, but when the room temperature of the building is relatively high, such as during midsummer, the power consumption of the air conditioning equipment of the building increases, Since the electric power that can be distributed to the elevator is reduced, there is a concern that the number of elevators operated and the traveling speed of the car will decrease, and the operation efficiency of the car will deteriorate.

  In addition, the elevator group management control device of the prior art distributes to the elevators by adopting the upper limit of the allowable value described above during times when the usage rate of the elevator is high, such as work hours and lunch hours. The power that can be increased. However, the amount of power that can be supplied to the elevators and other facilities does not increase, so if the power consumption of the building's air conditioning facilities increases as in midsummer, the amount of power distributed to the elevators increases. The amount will also be limited. Therefore, even if the usage rate of the elevator is high, it is not possible to secure the number of elevators operated, and there is a concern that the convenience and serviceability of the elevator for passengers will be reduced.

  The present invention has been made based on such a state of the art, and an object of the present invention is to provide an elevator group management control device that can effectively use the power of a building and can secure the number of operating elevators. It is to provide.

Thereby, even if it is a time slot | zone with a high utilization factor of an elevator, since operation | movement of a car can be performed efficiently, a passenger's waiting time can be reduced.

  On the other hand, in times when there are few people working in the building, such as work hours and lunch hours, the power shut-off means uses the amount of power supplied by the power supply means and the amount of power calculated by the power amount calculation means. Based on the above, by blocking the supply of power to at least one of the air conditioning equipment and lighting equipment, the power to be supplied to the elevator is secured as described above, and the remaining power is appropriately supplied to the air conditioning equipment and lighting equipment.

It is characterized by opening.

  In the present invention configured as described above, the priority order setting means sets the order of the equipment for preferentially cutting off the power supply among the air conditioning equipment and the lighting equipment, and opens each switch in the set order. Therefore, it is possible to prevent the air conditioning equipment and the lighting equipment from being inadvertently shut off. In addition, since the facility to be shut off can be selected after checking the indoor use situation and the room temperature of the building, the indoor environment of the building can be flexibly adjusted even during work hours and lunch hours.

Specifically, the power shut-off means is provided in the power supply circuit 7, and is opened / closed to electrically cut or connect the power supply circuit 7, and the common-part air conditioning equipment 5a, floor air-conditioning equipment 5b to 5n, measuring means for measuring the amount of power used in the common area lighting equipment 6a, and the floor lighting equipment 6b to 6n, and the amount of power supplied by the power source 1 and the amount of power calculated by the power amount calculation means Computing means for computing the difference.

  The above-described switching means includes, for example, a plurality of switches 7a1 to 7n1 provided on the shared air conditioner 5a side and floor air conditioners 5b to 5n side in the power supply circuit 7, and the shared light illumination in the power supply circuit 7, respectively. It comprises a plurality of switches 7a2-7n2 provided on the facility 6a side and floor lighting facilities 6b-6n, respectively. These switches 7a1-7n1, 7a2-7n2 are inserted in the power supply circuit 7 in series, for example. ing.

  The power shut-off means opens the switches 7a1 to 7n1 and 7a2 to 7n2 when the amount of power measured by the measuring means exceeds the amount of power calculated by the computing means, and the amount of power measured by the measuring means is Power supply control means 2 is provided for controlling the switches 7a1 to 7n1 and 7a2 to 7n2 to close when the amount of power calculated by the calculation means is not exceeded.

  In this embodiment, the measuring means is stored inside the group management control means 3, the computing means is stored inside the power supply control means 2, and the group management control means 3 and the power supply control means 2 are connected to each other. . Therefore, the power amount calculated by the above-described power amount calculating unit and the information on the power amount measured by the measuring unit are transmitted from the group management control unit 3 to the power source control unit 2.

  In this embodiment, the group management control unit 3 calculates the difference between the amount of power supplied by the power source 1 and the amount of power measured by the measuring unit and can supply the power to each elevator (hereinafter, surplus power). A surplus electric power amount calculating means for obtaining (referred to as an amount). Further, the group management control means 3 calculates the division of the surplus power amount calculated by the surplus power amount calculation means and the elevator power consumption amount, so that the number of elevators that can be operated using the surplus power amount. The number of operating units is calculated.

  In the present embodiment, the power supply control means 2 is a facility that preferentially cuts off the supply of power among the common-part air conditioning equipment 5a, the floor air-conditioning equipment 5b-5n, the common-use lighting equipment 6a, and the floor lighting equipment 6b-6n. Priority order setting means for setting the order is included, and the switches 7a1 to 7n1 and 7a2 to 7n2 are opened in the order set by the priority order setting means. In addition, the power supply control means 2 has registered the power consumption amount required for each equipment 5a-5n and 6a-6n.

  Further, in the present embodiment, the power supply control unit 2 is calculated by the power amount measured by the measurement unit and the calculation unit when the power amount measured by the measurement unit exceeds the power amount calculated by the calculation unit. The amount of power that exceeds the maximum power supply amount of the power source 1 when the number of elevators corresponding to the amount of power calculated by the power amount calculation means is operated (hereinafter referred to as excess power amount). There is an excess power amount calculating means for calculating. The power supply control means 2 then switches each of the switches 7a1 to 7n1, 7a2 to 7n2 in the order set by the priority order setting means until the total power consumption corresponds to the excess power amount calculated by the excess power amount calculation means. To open.

  Therefore, when the order in the priority setting means is set in the order of, for example, the floor lighting equipment 6b, the floor lighting equipment 6c,..., The floor lighting equipment 6n, the power supply control means 2 uses the power amount measured by the measuring means. , Switch 7b2, switch 7c2,..., Switch 7n2 until the total power consumption of each switch 7b2 to 7c2 corresponds to the excess power. The switches 7b2 to 7c2 are opened in this order. In the present embodiment, the order in the priority order setting means is the common part air conditioner 5a, the floor air conditioners 5b to 5n, and the common part lighting equipment in the order of the common part of the building and the floors A to N that are used less frequently. 6a and floor lighting equipment 6b to 6n are set to be cut off from power supply.

  Next, the operation of the present embodiment will be described based on the flowchart of FIG.

  FIG. 2 is a flowchart for explaining the operation of this embodiment.

  In this embodiment, first, as shown in FIG. 2, the group management control means 3 determines whether the current time is a work time zone or a lunch time zone by a timer (step (hereinafter referred to as S) 1). At this time, when the group management control means 3 determines that it is not a work time zone or a lunch time zone, that is, in a time zone during which work is performed in the building, the measurement means is configured to use the common part air conditioning equipment 5a, The amount of power used in the floor air-conditioning equipment 5b to 5n, the common section lighting equipment 6a, and the floor lighting equipment 6b to 6n is measured, and the surplus power amount calculation means of the power supply control means 2 is the surplus power that can be supplied to each elevator. The amount is calculated and obtained (S2).

  Next, the operation number calculation means of the group management control means 3 calculates the number of elevators that can be operated using the surplus power amount calculated by the surplus power amount calculation means in step S2 (S3). Then, the group management control means 3 operates the number of elevators calculated by the operating number calculation means in step S3 (S4), and ends the operation of this embodiment.

  On the other hand, when the group management control means 3 determines in step S1 that it is a working time zone or a lunch time zone, the power amount calculation means of the group management control means 3 considers the maximum power supply amount of the power source 1. The maximum electric energy of the elevator that can be operated is calculated (S5). Next, the measuring means measures the amount of electric power used in the common part air conditioning equipment 5a, the floor air conditioning equipment 5b-5n, the common part lighting equipment 6a, and the floor lighting equipment 6b-6n, and the arithmetic means is powered by the power source 1. The difference between the supplied power amount and the power amount calculated by the power amount calculating means is calculated (S6).

  And the power supply control means 2 judges whether the electric energy measured by the measurement means exceeds the electric energy calculated by the calculating means (S7). At this time, when the power supply control unit 2 determines that the amount of power measured by the measurement unit does not exceed the amount of power calculated by the calculation unit, the power supply control unit 2 switches the switches 7a1 to 7n1 and 7a2 to 7n2. Is kept closed (S8), and the group management control means 3 operates the number of elevators corresponding to the amount of power calculated by the power amount calculation means in step S5 (S9), and the operation of the present embodiment Exit.

  On the other hand, when the power supply control means 2 determines in step S7 that the amount of power measured by the measurement means exceeds the power amount calculated by the calculation means, the excess power amount calculation means of the power supply control means 2 determines in step S5. When the number of elevators corresponding to the amount of power calculated by the power amount calculation means is operated, an excess power amount exceeding the maximum power supply amount of the power source 1 is calculated (S10).

  Thereafter, the power supply control means 2 switches the switches 7a1 to 7n1, until the sum of the power consumption amounts of the respective switches 7a1 to 7n1, 7a2 to 7n2 corresponds to the excess power amount calculated by the excess power amount calculation means in step S10. 7a2 to 7n2 are opened in the order set by the priority order setting means (S11). Then, the group management control means 3 operates a number of elevators corresponding to the amount of power calculated by the power amount calculation means in step S5 (S9), and ends the operation of this embodiment.

  According to the present embodiment configured as described above, when the current time measured by the timer in step S1 becomes a work time zone or a lunch time zone, people in and out of the building become intense, so the common part air conditioner 5a, floor Rather than distributing power from the power source 1 to the air conditioning facilities 5b to 5n, the common area lighting facilities 6a, and the floor lighting facilities 6b to 6n, as many passenger cars 4a to 4n as possible can be operated. It is better to let them.

  Therefore, after the power amount calculating means calculates the maximum power amount of the elevator that can be operated in consideration of the maximum power supply amount of the power source 1 in step S5, the group management control means 3 performs this power amount in step S9. By driving the number of elevators equivalent to the number of elevators, it is possible to efficiently operate the cars 4a to 4n during times when the elevator usage rate is high, such as working hours and lunch hours. Passenger waiting time can be reduced.

  On the other hand, in the time zone where the current time measured by the timer in step S1 is a time zone other than the work time zone or the lunch time zone, for example, when there are many people working in the building, the common area air conditioner 5a and the floor air conditioner 5b. It is better to keep the indoor environment comfortable by distributing the power of the power source 1 to ˜5n, the common part lighting equipment 6a, and the floor lighting equipment 6b to 6n.

  Therefore, in step S8, the power supply control unit 2 closes the switches 7a1 to 7n1 and 7a2 to 7n2 based on the amount of power supplied from the power source 1 and the amount of power calculated by the power amount calculation unit, and the common unit air conditioning equipment 5a, floor air-conditioning equipment 5b-5n, common-use lighting equipment 6a, and floor-lighting equipment 6b-6n by appropriately shutting off the power supply to ensure the power to be supplied to the elevator, the remaining power is shared It can be appropriately distributed to the air conditioning equipment 5a, floor air conditioning equipment 5b to 5n, common area lighting equipment 6a, and floor lighting equipment 6b to 6n. In particular, when there is a margin in the amount of power of the power source 1, the amount of power that can be supplied to the elevator increases, so the number of elevators can be increased. As described above, the power of the building can be used effectively, and the number of elevators operated can be secured, so that the operation efficiency of the cars 4a to 4n can be improved, and the convenience of the elevator for passengers and Serviceability can be improved.

  Further, in the present embodiment, the power control unit 2 uses the excess power calculated by the excess power calculation unit in step S10 when the amount of power measured by the measurement unit exceeds the power amount calculated by the calculation unit. Until it corresponds to the quantity, by opening the switches 7a1 to 7n1, 7a2 to 7n2 in step S11, the common part air conditioning equipment 5a, the floor air conditioning equipment 5b to 5n, the common part lighting equipment 6a, and the floor lighting equipment 6b from the power source 1 Since the power transmission to ˜6n can be cut off quickly, the amount of power used even if the maximum number of elevators that can be operated in the range of the supply capacity of the power supply 1 in the step S9 is operated simultaneously. It can be sufficiently suppressed below the supply capacity.

  On the other hand, when the power amount measured by the measuring unit does not exceed the power amount calculated by the calculating unit, the power source control unit 2 closes the switches 7a1 to 7n1 and 7a2 to 7n2 in step S8, thereby Since power transmission from 1 to the common area air conditioning equipment 5a, floor air conditioning equipment 5b to 5n, common area lighting equipment 6a, and floor lighting equipment 6b to 6n is continued, the comfort of the space in the building should be maintained. Can do. In this way, it is possible to provide a comfortable living environment according to the activity status in the building.

  Moreover, this embodiment is a facility that preferentially cuts off the supply of electric power among the common unit air conditioner 5a, floor air conditioners 5b to 5n, common unit lighting facility 6a, and floor lighting facilities 6b to 6n by the priority setting means. Since the switches 7a1 to 7n1 and 7a2 to 7n2 are opened in the order set by the priority order setting means in step S11, the common unit air conditioning equipment 5a and floor air conditioning equipment 5b to 5n, common use lighting equipment 6a, and floor lighting equipment 6b-6n can be prevented from being cut off carelessly.

  Further, in the present embodiment, the priority order setting unit ranks the common part air-conditioning equipment 5a, the floor air-conditioning equipment 5b to 5n, and the common-use lighting equipment in the order of the common part of the building and each of the floors A to N in the least frequently used room. 6a and floor lighting facilities 6b to 6n are set to cut off the power supply, so that the power of power supply 1 is shared air conditioning equipment 5a, floor air conditioning equipment 5b to 5n, common lighting equipment 6a, and floor Electric power can be efficiently transmitted to the lighting facilities 6b to 6n, and environmental changes during work hours and lunch hours can be suppressed.

  In the present embodiment described above, the order in the priority setting means is the common part air conditioner 5a, the floor air conditioners 5b to 5n, the common part in the order of the common part of the building and the floors A to N that are used less frequently. Although the case where it set so that supply of electric power of lighting equipment 6a and floor lighting equipment 6b-6n was cut off was explained, it is not restricted to this case, for example, it is shared rather than common part air-conditioning equipment 5a and floor air-conditioning equipment 5b-5n When it is desired to secure the power supply of the section lighting equipment 6a and the floor lighting equipment 6b to 6n, the order in the priority setting means is set from the common section air conditioning equipment 5a and the floor air conditioning equipment 5b to 5n, and the common section air conditioning equipment 5a. And floor air-conditioning equipment 5b-5n can be shut off preferentially.
