Elevator control gear 20 comprises drive division 21, electrical motor (M) 22 and control part 23.
Drive division 21 is by supplying driving motor 22 by the driving electric power of regulation to electrical motor 22.Specifically, drive division 21 is realized by not shown converter apparatus, smooth condenser and DC-to-AC converter etc.
Converter apparatus is connected with commercial power 1.Converter apparatus is made up of diode, and the three-phase ac power supplied from commercial power 1 is transformed to direct current power.
Pulsating quantity (ripple) smoothingization that smooth condenser comprises the direct current power after conversion in converter apparatus.

Control part 23 is function parts that the running carrying out elevator controls.In addition, control part 23 comprises detection unit 23a and operation control section 23b.
Whether the charge rate of the battery 11 when detection unit 23a judges the power failure detected by charge rate test section 12 is as more than prespecified value (higher limit).Operation control section 23b carries out the control operating speed of elevator being changed based on the result of determination of detection unit 23a.
In addition, in the elevator device of present embodiment, electrical motor 22 become electrical generator carry out generating electricity such running (being denoted as regeneration operating below) time, produce electric power (being denoted as regenerated electric power below) due to this generating.
In addition, when supplying the usual running of electric power from commercial power 1, regenerated electric power is discharged into such as power feed line, is used in the above-mentioned supply of the electric power to various equipment.On the other hand, when the power failure that the electric power supply from commercial power 1 stops, regenerated electric power is utilized to charge to battery 11.
Next, the action of the elevator device (electrical storage device 10 and elevator control gear 20) of present embodiment is described.At this, the process of the process of elevator device when usually operating and elevator device when having a power failure is described.
First, with reference to the diagram of circuit of Fig. 2, the process of elevator device during usual running to present embodiment is described.At this, be set to the situation utilizing the electric power supplied from commercial power 1 to charge to battery 11.
At this, the charge rate test section 12 that electrical storage device 10 comprises detects the charge rate (step S1) of battery 11.The charge rate of this battery 11 is detected as magnitude of voltage of battery 11 etc. by measurement example.In addition, the process of this step S1 is performed termly when usually operating.
Next, control part 13 judges that whether the charge rate of the battery 11 detected by charging test section 12 is as more than higher limit (the second higher limit) (step S2).Even if this higher limit is redefined for such as when utilizing the regenerated electric power produced by the regeneration operating of elevator when having a power failure to carry out charging to battery 11, the charge rate of this battery 11 also can not exceed the value of charging limit (that is, the charge rate of battery 11 is no more than 100%) degree.Specifically, the value in scope that higher limit is such as 70-90% is set to.In the following description, the higher limit used in step S2 is called higher limit during running usually.
When be judged to be the charge rate of battery 11 be usually operate time higher limit more than (step S2 is yes), control part 13 by controlling discharge and recharge portion 14, the electric power that utilization supply from commercial power 1 and charging stopping (step S3) of battery 11 carried out.
On the other hand, when be judged to be the charge rate of battery 11 be not usually operate time higher limit more than (step S2 is no), the process of step S3 is not performed.
By performing such process, the charge rate of the battery 11 when usually operating can be made to be that such as 80% (higher limit usually during running) below, can suppress battery 11 to be charged to charging limit (100%).
In addition, when utilizing the electric power of battery 11 in due to the supply of the power supply to various equipment when usual running and make the charge rate of this battery 11 lower than higher limit during usual running, again carry out the charging utilizing the electric power supplied from commercial power 1 and the battery 11 carried out, perform the process shown in above-mentioned Fig. 2.
Next, with reference to the diagram of circuit of Fig. 3, the process of elevator device during power failure to present embodiment is described.
In addition, when having a power failure, the electric power supply from commercial power 1 stops, and therefore, the electric power required for the power running of elevator is supplied by from battery 11.On the other hand, the regenerated electric power produced by the regeneration operating of elevator when having a power failure returns electrical storage device 10 from elevator control gear 20 (electrical motor 22 comprised) and is used in the charging of battery 11.
That is, during the power running of elevator when having a power failure, battery 11 is set as discharge regime, and during the regeneration operating of the elevator when having a power failure, battery 11 is set as charge condition.In addition, the switching of the discharge and recharge of this battery 11 is undertaken by discharge and recharge portion 14 based on the control of control part 13.
In addition, according to above-mentioned building management system, when having a power failure, in the middle of the various equipment that this building management system manages, only necessary MIN equipment (load) such as such as elevator and illumination etc. is supplied electric power by from electrical storage device 10 (battery 11).In addition, in the elevator device of present embodiment, even if also make elevator operate with command speed (that is, same with when usually operating speed) when having a power failure.
At this, the charge rate test section 12 that electrical storage device 10 comprises detects the charge rate (step S11) of battery 11.The charge rate (signal) of the battery 11 detected by charge rate test section 12 is like this transmitted to the control part 23 that elevator control gear 20 comprises.In addition, the process of this step S11 is performed termly when having a power failure.
The detection unit 23a that control part 23 comprises judges that whether the charge rate of the battery 11 sent from charge rate test section 12 is as more than higher limit (the first higher limit) (step S12).In addition, the higher limit (being denoted as higher limit during power failure below) in step S12 is the value higher than higher limit during usual running in the step S2 shown in above-mentioned Fig. 2, be such as 90-99% scope in value.
At this, the above-mentioned regenerated electric power amount produced by the regeneration operating of elevator depends on the operating speed of elevator (car 33).That is, the operating speed of the elevator when regeneration operating is high speed, regenerated electric power quantitative change is many.On the other hand, the operating speed of the elevator when regeneration operating is low speed, regenerated electric power quantitative change is few.
Therefore, when be judged to be the charge rate of battery 11 be have a power failure time higher limit more than (step S12 is yes), the operating speed that the operation control section 23b that control part 23 comprises carries out elevator when making regeneration operating carries out the control operated lower than command speed, to suppress the generation of regenerated electric power.Thus, the low-speed running (step S13) of elevator is started.
In addition, the regenerated electric power produced by the regeneration operating of elevator returns to electrical storage device 10 side as described above.If regenerated electric power returns electrical storage device 10 like this, utilize this regenerated electric power to carry out the charging of battery 11, but this regenerated electric power, except being used in the charging of battery 11, can also be used in each portion action that this electrical storage device 10 is comprised.That is, when the amount of regenerated electric power is less, even if become and create this regenerated electric power and battery 11 is not charged yet beyond the charging being used in battery 11 due to this regenerated electric power.
Therefore, when the charge rate of battery 11 be have a power failure time higher limit more than, the degree of operation control section 23b operating speed is lowered into only produce this battery 11 not charged regenerated electric power that (charging not affecting battery 11) measure operates.Such as, the operating speed of the elevator in this situation is 1/10 degree of command speed (operating speed usually during running).
On the other hand, when be judged to be the charge rate of battery 11 be not have a power failure time higher limit more than (step S12 is no), the process of step S13 is not performed.
By performing such process, the charge rate of the battery 11 when having a power failure is more than such as 95% (higher limit during power failure), by reducing operating speed, while the generation of regenerated electric power can be suppressed, running is continued.
In addition, according to above-mentioned process, even make the charge rate of battery 11 rise by operating speed is set to low speed during regeneration operating, and during power failure, the electric power required for power running of elevator is supplied by from battery 11.In this situation, the charge rate of battery 11 reduces down gradually along with the running of elevator.Therefore, after the low-speed running of elevator starts, there is the situation that the charge rate of the battery 11 detected termly is as described above lower than the higher limit (such as, 80%) during above-mentioned usual running.In this situation, in order to the charging that regenerated electric power can be utilized to carry out battery 11, regeneration operating is set to the running of command speed.Accordingly, when the charge rate of battery 11 reduces, the regenerated electric power produced by regeneration operating can be utilized to charge to battery 11.
As described above, in the present embodiment, have a power failure time be judged to be the charge rate of battery 11 be have a power failure time higher limit (such as, 95%) more than when, the operating speed of elevator is lowered into operate lower than command speed, to suppress the generation of regenerated electric power.Thus, in the present embodiment, the charge rate of battery 11 can be avoided to exceed charging limit (that is, the charge rate of battery 11 is more than 100%), the emergent stopping of elevator when having a power failure can be prevented.
In addition, in the present embodiment, the higher limit (such as 80%) when the charge rate of the battery 11 when usually operating (utilizing the electric power from commercial power 1 by the charge rate of battery 11 of charging) being set to running usually below.Thereby, it is possible to allowed some leeway before the charge rate of battery 11 reaches charging limit.Therefore, in the present embodiment, even if also can prevent the charge rate of battery 11 from exceeding charging limit when creating regeneration operating continuously in the running of the elevator after just having a power failure.
Specifically, according to the present embodiment, the charge rate of the battery 11 when usually operating and when having a power failure is passed, as shown in Figure 4 therefore, it is possible to avoid the charge rate of battery 11 to exceed charging limit.
In addition, more than the higher limit when the charge rate of battery 11 is power failure, also can be configured to, consume the electric power supplied from this battery 11 more, the charge rate of battery 11 is reduced.
Specifically, also can be, even if the operating speed when making regeneration operating is as described above lowered into when operating lower than command speed, when elevator carries out power running, also the operating speed of this elevator is set to command speed.According to such formation, the electric power supplied from battery 11 can be consumed more, therefore, it is possible to prevent the charge rate of battery 11 from exceeding charging limit.In addition, the power running of elevator also can be differentiated in elevator control gear 20 by the information of the load and destination floor that obtain car 33 before the running of elevator.
In addition, in order to consume the electric power supplied from battery 11 more, also can be configured to, the operating speed of elevator when making elevator carry out power running improves into and operates higher than command speed.
And, when the charge rate of battery 11 be have a power failure time higher limit more than and the power running of the elevator not having occupant ride can be carried out, also can be, by automatically carrying out this power running, consume the electric power from battery 11, the charge rate of this battery 11 is reduced.In addition, what is called can carry out not having the situation of the power running of the elevator of occupant ride such as to comprise does not have the elevator of occupant ride (that is, the car 33 that duty ratio counterweight 34 is light) to the situation etc. of the lower direction movement of lift path.
In addition, in the present embodiment, the situation being contained in electrical storage device 10 with battery 11 is illustrated, but this battery 11 such as also can be disposed in elevator control gear 20.In this situation, elevator control gear 20 comprises the function part suitable with charge rate test section 12, in this elevator control gear 20, perform the process shown in above-mentioned Fig. 2 and Fig. 3.
(the second embodiment)
Next, the second embodiment is described.Fig. 5 is main portion as the elevator device of the elevator control gear comprised involved by present embodiment and the figure of functional structure is shown.
In addition, for the part same with described Fig. 1, also description is omitted to give identical reference marker.At this, the part that main description is different from Fig. 1.
As shown in Figure 5, elevator device comprises electrical storage device 100.Electrical storage device 100 comprises device of solar generating 101.

In the present embodiment, the battery 11 that comprises of electrical storage device 100 when running usually and the time of power failure can utilize the electric power that generated electricity by such device of solar generating 101 and be charged.
Next, the action of the elevator device (electrical storage device 100 and elevator control gear 20) of present embodiment is described.At this, the process of the process of elevator device when usually operating and elevator device when having a power failure is described.
First, the process of elevator device during usual running to present embodiment is described.At this, conveniently, be described with reference to the diagram of circuit shown in above-mentioned Fig. 2.At this, utilize the electric power supplied from commercial power 1 and the electric power obtained from device of solar generating 101 to carry out the charging of battery 11.
In the process of the elevator device when the usual running of present embodiment, same with the first described embodiment, perform the step S1 shown in Fig. 2 and S2.
When being judged to be that the charge rate of battery 11 is more than higher limit when usually operating in step s 2, control part 13 in step s3, makes the charging of battery 11 stop by controlling discharge and recharge portion 14.In this situation, the charging of the battery 11 undertaken by the electric power supplied from commercial power 1 and the electric power generated electricity by device of solar generating 101 is stopped.In this situation, the electric power generated electricity by device of solar generating 101 is not used in the charging of battery 11, and is used in the electric power supply etc. to the various equipment (load) comprising elevator control gear 20.
By performing such process, the charge rate of the battery 11 when usually operating is made to be that such as 80% (higher limit usually during running) below, can suppress battery 11 to be charged to charging limit (100%).
In addition, as described above, the process of elevator device during usual running about present embodiment, the electric power supplied from commercial power 1 except making utilization in above-mentioned step S3 and the electric power that generated electricity by device of solar generating 101 and the charging of battery 11 carried out stops except this point, same with the first described embodiment, therefore, description is omitted.
Next, with reference to the diagram of circuit of Fig. 6, the process of elevator device during power failure to present embodiment is described.
In addition, as described in the first embodiment in illustrated, have a power failure time, from commercial power 1 electric power supply be stopped, therefore, the electric power required for the power running of elevator is supplied by from battery 11.On the other hand, the regenerated electric power produced by the regeneration operating of elevator when having a power failure returns electrical storage device 100 from elevator control gear 20 (electrical motor 22 comprised) and is used in the charging of battery 11.And battery 11 utilizes the electric power that obtains from device of solar generating 101 and is charged.
That is, during the power running of elevator when having a power failure, battery 11 is set as discharge regime, and during the regeneration operating of the elevator when having a power failure, battery 11 is set as charge condition.In addition, the switching of the discharge and recharge of this battery 11 is undertaken by discharge and recharge portion 14 based on the control of control part 13.
In addition, same with the first described embodiment, according to above-mentioned building management system, when having a power failure, in the middle of various equipment, only necessary MIN equipment (load) such as such as elevator and illumination etc. is supplied electric power by from electrical storage device 100 (battery 11).Thus, in the elevator device of present embodiment, even if when having a power failure, elevator also can be made to operate with command speed (that is, same with when usually operating speed).
In the process of the elevator device when the power failure of present embodiment, first, the process of the step S21 suitable with the process of the described step S11 shown in Fig. 3 is performed.

When the charge rate being judged to be battery 11 is more than the higher limit of solar electrical energy generation (step S22 is yes), control part 13 is by controlling discharge and recharge portion 14, the charging of the electric power that utilization is obtained from device of solar generating 101 and the battery 11 that carries out (that is, utilize solar electrical energy generation and carry out charging) stops (step S23).In this situation, the electric power generated electricity by device of solar generating 101 is not used in the charging of battery 11, and is used in the electric power supply etc. to various equipment (such as, elevator control gear 20 and illumination etc.).
Next, the process of the step S24 suitable with the process of the described step S12 shown in Fig. 3 is performed.In addition, in the following description, conveniently the higher limit used in step S24 is called the higher limit of regenerated electric power.The higher limit of this regenerated electric power is the value identical with the higher limit during power failure illustrated in the first described embodiment, such as, be 95%.In addition, the higher limit of regenerated electric power is set to the value higher than the higher limit of above-mentioned solar electrical energy generation.
When the charge rate being judged to be battery 11 is in step s 24 which more than the higher limit of regenerated electric power, perform the process of the step S25 suitable with the process of the described step S13 shown in Fig. 3.
In addition, the charge rate being judged to be battery 11 in step S22 is not more than the higher limit of solar electrical energy generation, or when the charge rate being judged to be battery 11 is not in step s 24 which more than the higher limit of regenerated electric power, process terminates.
By performing such process, the charge rate of the battery 11 when having a power failure is more than such as 80% (higher limit of solar electrical energy generation), the electric power that utilization is obtained from the device of solar generating 101 and charging carried out stops, thus, inhibit the rising of the charge rate of battery 11.In addition, when the charge rate of battery 11 is more than such as 95% (higher limit of regenerated electric power), by reducing operating speed, while the generation of regenerated electric power can be suppressed, running is continued.
In addition, the charge rate of the battery 11 detected termly as described above after the low-speed running of elevator starts lower than higher limit during above-mentioned usual running (such as, 80%) when, in order to the charging that regenerated electric power can be utilized to carry out battery 11, regeneration operating is set to the running under command speed.Equally, the charge rate of this battery 11 is lower than prespecified value after the charging carried out when making to utilize solar electrical energy generation stops, by controlling discharge and recharge portion 14, the charging utilizing this solar electrical energy generation to carry out again is started.Thus, when the charge rate of battery 11 reduces, regenerated electric power and solar electrical energy generation can be utilized to carry out the charging of battery 11.
As described above, in the present embodiment, when the charge rate of battery 11 when having a power failure is more than the higher limit (such as, 80%) of solar electrical energy generation, the electric power that utilization is obtained from the device of solar generating 101 and charging of battery 11 carried out stops.In addition, when being more than the higher limit (such as, 95%) of regenerated electric power in the charge rate of battery 11, the operating speed of elevator being lowered into and operating lower than command speed, to suppress the generation of regenerated electric power.Thus, in the present embodiment, the charge rate of battery 11 can be avoided to exceed charging limit (that is, the charge rate of battery 11 is more than 100%), the emergent stopping of elevator when having a power failure can be prevented.
