Summary of the invention
But, according to described patent documentation 1 disclosed technology, in order to obtain cutting down the electric energy generated of accumulator capacity, then need to increase the driving rolls of electrical generator, and a plurality of electrical generators be set.When if the rating horsepower of the air conditioner of lift car more for example reaches several kW, the capacity of storage battery also will reach this rank of kWh, and cause the scale of storage battery to increase.
As cutting down this capacity, then need to increase the electric energy generated of electrical generator, and in order to improve generated output, the quantity that needs to use large electrical generator and need to increase electrical generator.In addition, in order to reduce skidding of driving rolls, need to add good general's driving rolls by the strength that is pressed on the guide rail, and the friction of driving rolls is strengthened, and cause the Speed Reduction of lift car.For fear of the generation of this situation, need to increase be used for drive the winch of electrical motor etc. of lift car and the rating horsepower of inverter, to increase horsepower output.Its result, because the increasing of the scale of winch and inverter, so the problem that existence can cause the scale of whole elevator device to strengthen.And, because a plurality of high-performance electrical generators need to be set, so also existence can cause manufacturing cost to increase and the problem of the weight increase of lift car etc.In addition, also can produce noise because of the friction between driving rolls and the guide rail.Therefore, the capacity that is difficult to the decrease storage battery.
In addition, according to patent documentation 2 disclosed technology, when the surplus of storage battery reduces, when the surplus that perhaps predicts storage battery will reduce, the floor standby that lift car is driven to be provided with charging unit.For example, if the non-contact power supply device is arranged on the lobby floor in the 1st building etc., then in time period that people go out to have lunch or next time period etc., when each floor of high-rise section has occured to go to the elevator lobby calling of lobby floor, because lift car need to spend considerable time in the lobby floor standby so elevator drives to high-rise elevator lobby calling genetic horizon at this moment.For this reason, can cause passenger's wait time elongated.
The elevator in especially high-rise zone (when for example the elevator parking floor is set in the 1st building and the 30th buildings to the 40th building) is because lobby floor is very long with distance between other floor, so this problem is more for seriously.In addition, if for fear of this situation occurring, and for example when a plurality of floors arrange respectively a plurality of non-contact power supply device, except meeting causes the cost of device increases, also can increase the reconstruction cost of building.For fear of above-mentioned 2 kinds of situations occurring, its result has to increase the capacity of storage battery.
In addition, according to patent documentation 3 disclosed technology, in order to reduce the capacity that is installed in the storage battery on the lift car, need to a considerable amount of electric supply installations be set in the building side.According to the record of patent documentation 3, be at each storey setting electric supply installation, for example at the electric supply installation of each storey setting lift car in the building of 10 floors, then its cost (installation cost and building reconstruction cost) will become very large.In addition, owing to need to carry out at each floor the maintenance of electric supply installation, so also need to spend corresponding labour power.On the other hand, if reduce the quantity of electric supply installation, then owing to the chance that can charge reduces, thereby need to strengthen the capacity that is installed in the battery on the lift car, its result can cause the weight of lift car to increase, so that the scale of whole elevator device increases.
Except the problem of above-mentioned storage battery aspect, owing to all the output of air conditioner is set as maxim when resting in the regulation floor at every turn, so may appear in the situation that does not need strong air-supply, the situation that air conditioner still moves with strong air supply pattern, like this, may can make on the contrary the passenger who takes advantage of into elevator feel uncomfortable because of strong air-conditioning output.

Its result when powering from storage battery to air conditioner, may cause the charge capacity of storage battery that deficiency occurs halfway.In addition, when exception occurs, such as holding convention etc. when movable, when this activity begins and when finishing etc., it is very busy that the use of elevator can become, but owing to can't predict by learning data, so possibly can't accomplish suitable control is carried out in the output of air conditioner.
In addition, according to patent documentation 5 disclosed technology, within the busy time period, owing to the passenger is arranged at elevator up and down, so may cause air conditioner always with the high wind mode operation always.In addition, although few at the number of users of elevator at ordinary times, owing between each floor, there is the passenger who moves up and down, so have up and down elevator of passenger at each floor always, like this, may cause air conditioner to move with the high wind pattern always.Its result because the horsepower output of air conditioner increases, when powering from storage battery to air conditioner, may cause the charge capacity of storage battery that deficiency occurs halfway.
As mentioned above, according to above-mentioned patent documentation 1～5 disclosed technology, when implementing elevator without stern fast, although can reduce the capacity that is installed in the storage battery on the elevator, but the apparatus structure that whole elevator device may occur increases, and perhaps causes elevator passenger in the new problem of the elongated grade of the wait time of elevator lobby.Therefore, when adopting said method, can bring very large harmful effect to other side, and be difficult to substantially reduce the capacity of storage battery.
In addition, aspect the consumed power of the air conditioner that suppresses lift car, also be difficult to be implemented in simultaneously according to the passenger's of lift car situation and require air conditioner is carried out suitable control, and the unnecessary output action of eliminating this air conditioner is with these two targets of power of inhibiting consumption.Its result if adopt above-mentioned technology in the air conditioner control without the elevator of stern fast, then is difficult to reduce the capacity that is installed in the storage battery on the lift car.Therefore, above-mentioned various technology all are difficult to substantially reduce the capacity of storage battery, thereby can't avoid the weight of storage battery to increase, and can offset the lightweight effect of bringing without stern fast.

Electrical equipment beyond the air conditioner in the lift car also is the same, such as devices such as illumination equipment and electronic guiding devices (will and drive be used to device, the magnetic guide boot of having of making that lift car successfully moves up and down and wheel similar action the guiding device that acceptances such as guide roller powers at this and be referred to as electronic guiding device), owing to can regulate its operation output according to the actual state of this device, so can reduce the capacity of storage battery.This is the related invention of power control apparatus of the lift car in the third embodiment of the invention.In Figure 10 to Figure 11, it is had been described in detail.
On the other hand, when reducing the capacity of storage battery, the worst situation to occur in order guarding against, to be necessary to establish the processing method when the residual quantity of electricity accumulation deficiency has occured.At this moment, in order to adapt with remaining charge capacity, can consider to adopt the method that various electrical equipments are stopped, and the related invention of the power control apparatus of the lift car in the four embodiment of the invention is exactly the invention that with suitable order various electrical equipments is stopped as mentioned above.In Figure 12 and Figure 13, it is had been described in detail.
In addition, storage battery is divided into main storage battery and subsidiary battery arranges, be responsible at ordinary times the electrical equipment in the lift car being powered by main storage battery, just in case when under-charge has occured in main storage battery, power by the subsidiary battery as wrecking equipment, to avoid occuring the situation of electricity shortage, what relate to this invention is the power control apparatus of the lift car of the 5th embodiment.At this, use the storage battery that can carry out fast charging and discharging as subsidiary battery, thus, when resting in the floor that can charge, can carry out fast charge, and repeat discharge for auxiliary main storage battery in that situation in addition is next, like this, can in section sometime, remedy the deficiency of main storage battery.In Figure 14 to Figure 16, it is had been described in detail.
Except carrying out without the stern fast, it is also conceivable that current limit in less scope, can reduce thus the diameter of the electric wireline part in the stern fast, thereby realize the lightweight of stern fast.
Concrete method is, by stern fast the storage battery that is installed on the lift car charged from the building power supply with little electric current at night, by storage battery and this dual mode of stern fast the car power apparatus powered by day.At this moment, can realize the lightweight of stern fast, and, owing to also can utilize stern fast to power by day, therefore can reduce the capacity that is installed in the storage battery on the lift car.What relate to this invention is the power control apparatus of the lift car of the 6th embodiment of the present invention.In Figure 17 to Figure 20, it is had been described in detail.

What be used for the power supply between this each electrical equipment 11～16 of control and the storage battery 34 and be subjected to the electricity relation is car Power Control Unit 2 as " car power control unit " of the present invention.
Car can be to sending controling instructions such as the various electrical equipments 11～16 of the lift car that comprises air conditioner 11 and illumination equipment 12 and accumulator control devices 35 with Power Control Unit 2, with the adjusting of the operation output of controlling various electrical equipments 11～16 and action stop and storage battery 34 discharge and recharge action etc.
Concrete method is, input message of brightness and elevator position etc. etc. is controlled in the lift car temperature that car detects according to the temperature regime in the outside air temperature that utilizes state, building of the residual quantity of electricity accumulation state of storage battery 34, elevator, building, by cab interior temperature sensor 17 with Power Control Unit 2, the lift car that detected by cab interior illuminance transducer 18, so that storage battery 34 carries out the suitable action that discharges and recharges, and make various electrical equipments 11～16 carry out suitable run action by control.
The information that comprises acquisition from the temperature sensor 601～605 of elevator control gear 44A described later (in the input car patronage, position and be in the information that the stop state still is in motoring condition etc.), remotely administered server 52 (input weather information etc.), group management control apparatus 51 (information of input flow of the people etc.) and each floor in the input information of car with Power Control Unit 2.And above-mentioned symbol 44A, 52,51,601～605 has done expression in overall system structure figure shown in Figure 7 described later.
Fig. 2 is the diagram of block that expression car shown in Figure 1 is used the inner structure of Power Control Unit 2.Car shown in Figure 2 is to judge carry out (1) master mode that output is regulated to air conditioner or (2) by the master mode (also can select two kinds of master modes all not carry out) of building Power supply with the function of Power Control Unit 2, to being judged as the suitable controlling quantity of master mode computing that carry out, and send control command to air conditioner 11 or storage battery 34.
As shown in Figure 2, car is regulated part 202, air-conditioning control command conversion fraction 203, master mode judgment part 204, air-conditioning instruction regulated quantity arithmetic section (air conditioner adjusting pattern) 205, air-conditioning instruction regulated quantity arithmetic section (building electric source modes) 206 and storage battery control command setting section (building electric source modes) 207 formations with Power Control Unit 2 by car air-conditioning instruction setting section 201, air-conditioning instruction.The function that described each construction module has partly illustrates in aftermentioned.
When carrying out the control of air conditioner 11, processed according to the order of sequence by car air-conditioning instruction setting section 201, air-conditioning instruction adjusting part 202 and air-conditioning control command conversion fraction 203, determine thus the air conditioner control command, and send to air conditioner 11.In car air-conditioning instruction setting section 201, will be set as initial value according to the control command that existing air-conditioning control determines.As this instruction, such as exemplifying out target temperature (expected value of cab interior temperature) and target output (the horsepower output expected value of air conditioner 11) etc.In part 202 is regulated in the air-conditioning instruction, according to the instruction that in car air-conditioning instruction setting section 201, determines, according to the regulated quantity of in air-conditioning instruction regulated quantity arithmetic section 205, trying to achieve, be suitable value with the size adjustment of air-conditioning instruction.
In air-conditioning control command conversion fraction 203, unit or the form of signal are carried out conversion, will become to send to through the air-conditioning instruction map of overregulate the signal form of the control command of air conditioner 11.The method of conversion changes according to the method for reseptance of the control command of air conditioner 11.
For example, air conditioner 11 receive be target temperature the time, air-conditioning control command conversion fraction 203 is carried out conversion with coefficient 1, and will directly send to air conditioner as control command through the target temperature of overregulate.And when air conditioner 11 received output power instruction, if when the air-conditioning instruction of overregulate is target temperature, according to the deviation between the temperature in target temperature and the current lift car it is transformed to the horsepower output instruction by air-conditioning control command conversion fraction 203.When air conditioner 11 receives the ON/OFF instruction, then open/close temporal mode is set, so that to have passed through the air-conditioning instruction (output of part 202 is regulated in the air-conditioning instruction) of regulating consistent with the aviation value of specified time, and be transformed to the open/close instruction of output according to this temporal mode.
When carrying out the adjusting action of air-conditioning instruction adjusting part 202, at first judge that by master mode judgment part 204 execution (1) regular event, (2) air conditioner regulate any master mode in pattern and (3) building electric source modes, switch thus and separately the corresponding regulated quantity arithmetic section 205～206 of master mode.To implement to switch by change-over switch 208 specifically.
At this, the action when so-called regular event refers to that air conditioner described later is regulated pattern and building electric source modes and all do not carried out is not namely regulated in the part 202 to air-conditioning instruction in the air-conditioning instruction and is regulated.In the input information master mode judgment part 204 with the residual quantity of electricity accumulation of storage battery, the position of predicting residual quantity of electricity accumulation, outside air temperature and lift car and state (be in halted state or be in motoring condition etc.) etc., so that the state suitable according to this condition selecting.For example, few in the residual quantity of electricity accumulation of storage battery 34, and outside air temperature for fear of the situation that the residual quantity of electricity accumulation deficiency occurs, selects air conditioner to regulate pattern when higher than specified value.
In air-conditioning instruction regulated quantity arithmetic section 205, according to the passenger take advantage of car floor, take advantage of the information of patronage and the specified seating capacity of car etc. in number, outside air temperature, the car to come the regulated quantity of computing air-conditioning instruction.Relation between each input and the regulated quantity has example input-output characteristic as shown in Figure 4 and Figure 5.To describe with reference to Fig. 4 and Fig. 5 below about these.
If when in master mode is judged, having selected the building electric source modes, carry out computing by 206 pairs of air-conditioning instructions of air-conditioning instruction regulated quantity arithmetic section regulated quantity of building electric source modes.The input message of this moment is temperature and the interior patronage of car in the car.When regulating the air-conditioning instruction according to the air-conditioning instruction regulated quantity that calculates at this, in storage battery control command setting section 207, set the storage battery control command and send it to accumulator control device (Fig. 1 35).To illustrate below about the building electric source modes, because it can be when lift car 1 rests in the floor that can charge, not passing through building side power supply 20 by storage battery 34 directly powers to the electrical equipment 11～16 in the car, so, output by strengthening as much as possible air conditioner 11 (for this reason, regulated quantity has the trend greater than former instruction), come the fast approaching target temperature, the discharge power that makes simultaneously storage battery 34 is zero, thus the effect with residual quantity of electricity accumulation of keeping storage battery 34.
Fig. 3 is the car of presentation graphs 2 with the diagram of circuit of the action of the master mode judgment part 204 of Power Control Unit 2.Be elaborated referring to the judgement action to master mode judgment part 204 of the diagram of circuit of Fig. 3.
At first, judge that in master mode judgment part 204 whether the residual quantity of electricity accumulation of storage battery 34 is than threshold value 1 little (step ST10).When being judged as than threshold value 1 greatly (step ST10 "No"), judge that further whether the predictor of residual quantity of electricity accumulation is than threshold value 2 little (step ST11).If when still being judged as than threshold value 2 greatly (step ST11 "No"), then can think also have enough residual quantity of electricity accumulation, therefore not implement the air-conditioning instruction and regulate (step ST12).And when residual quantity of electricity accumulation than threshold value 1 hour (step ST10 "Yes") or surplus predictor than threshold value 2 hours (step ST11 "Yes"), the situation of residual quantity of electricity accumulation deficiency then may appear, at this moment, carry out following judgement and process.
That is to say, at first, if lift car 1 is in halted state, and the position of lift car 1 be provided with and can (be provided with power supply among Fig. 1 with voltage transformer 23 to the electric supply installation of lift car 1 power supply, when the floor floor of inverter 22 and changer 21 devices) is consistent (step ST13 "Yes"), make master mode judgment part 204 can be by the electric supply installation 21 of hoist trunk 23 sides, 22,23 and the electric supply installation 3 of lift car powered to the electrical equipment 11～16 of lift car 1 by building side power supply (Fig. 1 20), and make the judgement (step ST14) of implementing the building electric source modes.
If lift car 1 is not in halted state, perhaps the position of lift car 1 be provided with (step ST13 "No") can be inconsistent to the floor of the electric supply installation of lift car 1 power supply the time, then master mode judgment part 204 judges that whether outside air temperature is than threshold value 3 little (step ST15).At this, if outside air temperature is judged as than threshold value hour (step ST15 "Yes"), even then make the judgement that also can not bring too large human discomfort to the passenger is regulated in the output of air conditioner 11, therefore, made entering the judgement that air conditioner is regulated pattern (step ST16).In addition, if outside air temperature is judged as (step ST15 "No") when larger than threshold value, then makes the passenger and wish to carry out thermoregulator judgement, and make the judgement (step ST17) of carrying out regular event.
In the judgement example of above-mentioned master mode shown in Figure 3, when master mode judgment part 204 is provided in the judgement of whether implementing air conditioner adjusting pattern, with the position of lift car 1 and outside air temperature etc. as the condition of judging, but also can be arranged to not according to above-mentioned condition judgment, and for example when the residual quantity of electricity accumulation of storage battery 34 or its predictor are lower than threshold value, directly make entering the judgement that air conditioner is regulated pattern.At this moment, can control as direction to keep storage battery 34 residual quantity of electricity accumulation.
Fig. 4 (a) and (b) be the diagram of curves of the input-output characteristic of the control in the expression air conditioner adjusting pattern.Specifically, this diagram of curves (characteristic) uses when determining air-conditioning instruction regulated quantity by air-conditioning instruction regulated quantity arithmetic section 205.
Controller characteristic curve when Fig. 4 (a) expression is not regulated air conditioner 11 according to outside air temperature.In the diagram of curves of Fig. 4 (a), transverse axis represents to take advantage of into the number of lift car and the ratio of the specified passenger of car from a certain floor, the output of the air conditioner of (regulating part 202 by the air-conditioning instruction of Fig. 2 regulates rear) after the longitudinal axis represents to regulate.The A1 of Fig. 4 (a) represents to take advantage of the characteristic when being lobby floor into floor, and it is the characteristic during floor beyond the lobby floor that A2 represents to take advantage of into floor.
It is generally acknowledged, because the interior environment system of inside, building is carrying out suitable operation always, so, staying in before this people in the building when taking elevator always, its requirement to the air-conditioning in the lift car is not very high.In contrast, the people who has just entered the building from the outside is when taking elevator, because it is under the outside air temperature environment before this always, so can feel consumingly be starved of air-conditioning in lift car.
Therefore, if according to both different demands the output of air conditioner 11 is regulated, just can suppress the output of air-conditioning integral body.Generally all enter from lobby floor owing to enter the people in building from the outside, and take advantage of into elevator in lobby floor, so, can whether be that lobby floor judges whether the needs air-conditioning according to taking advantage of into floor.
What this 2 Gent linearity curve of the A1 of Fig. 4 (a) and A2 represented is exactly above-mentioned situation, with take advantage of the characteristic curve (A1) when being lobby floor into floor and compare, be beyond the lobby floor in the characteristic curve during floor taking advantage of floor, the output of air conditioner 11 has been lowered.In addition, not only taking advantage of into floor is key factor when determining air conditioner 11 output, takes advantage of into the number of floor also very important when determining the output of air conditioner 11.For example, if take advantage of small into elevator from lobby floor, then there is no need to improve significantly the output of air conditioner 11.In order to reflect this point, in the characteristic curve of the A1 of Fig. 4 (a) and A2, along with the increase of taking advantage of into number, the air-conditioning output after the adjusting also increases.
According to the characteristic shown in Fig. 4 (a), output by adjusting air conditioning 11, air-conditioning can be distributed to from lobby floor with exporting emphasis and be taken advantage of the passenger who is starved of air-conditioning into elevator, simultaneously floor beyond the lobby floor is taken advantage of the passenger who not too needs air-conditioning into elevator, then can suppress air-conditioning output.
Its result can in that elevator passenger is felt in the offending situation, reduce the output electric energy of air conditioner 11 integral body.In addition, by according to take advantage of from lobby floor into the patronage of elevator and beyond the lobby floor floor take advantage of the patronage into elevator to carry out above-mentioned adjustment, can carry out suitable adjusting according to taking advantage of into number, thereby can further enough suppress the output electric energy of air conditioner 11.Therefore, when the residual quantity of electricity accumulation of storage battery 34 is few, can by carry out above-mentioned adjusting, suppress the consumed power of air conditioner 11, thereby can slow down the minimizing degree of residual quantity of electricity accumulation.That is to say, can when realizing without the stern fast elevator, reduce the essential capacity of storage battery.
In addition, when calculating is taken advantage of into number, change average weight divided by everyone by the time dependent that will be arranged on the load data value that the underfloor not shown load cell of lift car detects, can try to achieve estimated value.In addition, at this supplemental instruction a bit, may there be the people to worry, from air conditioner 11 changes output, arrive till the actual change of temperature in the lift car, need to be through after a while, but actually, when the cold wind that blows out from air conditioner 11 (be not general ventilation, but with the wind of cold air) when blowing on the person, just can make the people produce nice and cool sensation, therefore control as described above is actually enough, in addition, compares with the temperature in reducing whole car, required air conditioner output is less, so also can suppress required electric flux in this.
Controller characteristic curve when Fig. 4 (b) expression has been carried out regulating to air conditioner according to outside air temperature.In regulated quantity along with whether being the difference of the characteristic that causes of lobby floor and with to take advantage of increase into number to increase this characteristic identical with Fig. 4 (b).
The controller characteristic curve that the air conditioner of Fig. 4 (b) is regulated pattern is with the difference of the controller characteristic curve of Fig. 4 (a), taking advantage of when being lobby floor into floor, and this controller characteristic curve changes along with the variation of outside air temperature at this moment.In the example of Fig. 4 (b), be accompanied by outside air temperature and rise to 25 degree, 28 degree, 30 degree and 32 degree, the output of air conditioner is also such as characteristic curve A11, A12, A13, thereupon increase shown in the A14.The purpose of doing like this is for the passenger who takes advantage of from lobby floor into elevator, by carry out the adjusting of more careful air-conditioning output according to outside air temperature at this moment, to suppress the output of air-conditioning integral body.For example, in Fig. 4 (a), when determining air-conditioning output, do not consider this factor of outside air temperature, and just according to whether take advantage of into the passenger of elevator and take advantage of into number and decide air-conditioning output with identical characteristic from lobby floor, and in Fig. 4 (b), then externally temperature is not in the very high situation, suppress the output of air conditioner 11, so can suppress the output of air conditioner 11 integral body.
Fig. 5 represents to regulate the controller characteristic curve of pattern with the routine different air conditioner of the controller characteristic curve (b) from Fig. 4 (a).In addition, Fig. 5 is also corresponding with the input-output characteristic that the air-conditioning instruction regulated quantity arithmetic section that is used for the building electric source modes 206 employed adjustings shown in Figure 2 are controlled.
In Fig. 5, transverse axis represents the ratio of patronage and the specified seating capacity of car in the car, the output of the air conditioner of (regulating after part 202 regulates by the air-conditioning instruction of Fig. 2) after the longitudinal axis represents to regulate.As shown in Figure 5, it is more to have in the car patronage, and the air conditioner output after then regulating is the characteristic of corresponding increase (curve B 1) also.In addition, this characteristic (curve B 1) has the characteristic that is similar to 2 functions, when the number in the car increases, the output of air conditioner is correspondingly sharply increased.This is because in the ordinary course of things, when the patronage in the car is less, do not need the output of too large air conditioner, but along with the increase of number, the passenger can produce constriction and human discomfort psychologically, therefore needs to strengthen the output of air conditioner.And along with number further increases, people's body temperature also can cause temperature to rise, and therefore needs to strengthen the output of air conditioner.
Owing to be arranged to control according to the characteristic of Fig. 5 the output of air conditioner, crowded and carry out the output of centrality air-conditioning when really being sought after air-conditioning in car, so can suppress in other cases the output of air conditioner, thereby can suppress on the whole the output of air conditioner.
In addition, because in the building electric source modes, the position of lift car is limited in being provided with the floor to the electric supply installation of lift car power supply, so come the Applicable scope of Fig. 4 (a) of regulation output and method (b) narrower according to taking advantage of into floor, in contrast to this, controller characteristic curve shown in Figure 5 is more suitable.So the air-conditioning instruction regulated quantity computing (206) of the building electric source modes of Fig. 2 is carried out according to the characteristic of Fig. 5.
And patronage also can be obtained estimate after will being arranged on the average weight of load data value divided by everyone that lift car 1 underfloor load cell measures in the car.
Fig. 6 is that expression is regulated the processing flow chart of pattern by the air conditioner that air-conditioning instruction regulated quantity arithmetic section 205 carries out.Below, the action to air-conditioning instruction regulated quantity arithmetic section 205 is elaborated with reference to diagram of circuit shown in Figure 6.
At first, by air-conditioning instruction regulated quantity arithmetic section 205 judge the passenger take advantage of into floor whether be lobby floor (step ST20).At this, so-called lobby floor is not only to refer to a floor, and refer to have with the building outside the gangway that is communicated with, and numerous personnel are arranged from the floor (can be a plurality of floors) of this gangway turnover.Taking advantage of when being lobby floor into floor, calculate air-conditioning instruction adjustment factor K (step ST21) according to following operational formula (1).
K＝FA(P、T)…(1)
In the formula, FA represents the function of the air-conditioning instruction adjustment factor K value when determining that taking advantage of of passenger is lobby floor into floor, and its input-output characteristic is corresponding with the A11～A14 of Fig. 4 (b).P represents to take advantage of the ratio into the specified seating capacity of number and car taken advantage of into floor, and T represents outside air temperature.
According in the air-conditioning instruction adjustment factor K of this setting value, by air-conditioning instruction regulated quantity arithmetic section 205 adjusting air conditioning control commands, so that it becomes the air conditioner instruction that the characteristic with A11～A14 of Fig. 4 (b) matches.The adjusting of this air conditioner instruction is continued until that from change constantly the passenger of lift car is zero (passenger who takes advantage of all descend till the elevator), perhaps is continued until (step ST22) till this lift car change travel direction.When to take advantage of into floor be floor beyond the lobby floor, calculate air-conditioning instruction adjustment factor K (step ST23) according to following operational formula (2).
K＝FB(P)…(2)
In the formula, FB represent for determine the passenger to take advantage of into floor be the function of the K value during floor beyond the lobby floor, its input-output characteristic is corresponding with the A2 of Fig. 4 (b).P represents to take advantage of the ratio into seating capacity with the specified seating capacity of car of floor.At this, according to the air-conditioning instruction adjustment factor K adjusting air conditioning control command that sets, so that the characteristic of the A2 of this air conditioner instruction and Fig. 4 (b) matches.The setting value of this K is taken advantage of into floor at each and is upgraded, and implement the air-conditioning instruction by air-conditioning instruction regulated quantity arithmetic section 205 according to the K that sets and regulate, until the passenger of lift car be zero or lift car change (step ST24) till the travel direction.
So, because air-conditioning instruction adjustment factor K takes advantage of into floor, takes advantage of into number and the outside air temperature of floor and set, so can set as required the output of air-conditioning, its result according to the passenger, owing to can suppress unnecessary air-conditioning output, so can suppress the output electric energy of air conditioner integral body.Therefore, carry out elevator without stern fast the time, can lower the necessary capacity that is installed in the storage battery 34 in the lift car.
The second embodiment
Referring to Fig. 7 to Fig. 9 to by electric supply installation from building side power supply 20 directly the power control apparatus of the related lift car of the second embodiment of the invention of electrical equipments 11～16 (representing with 11A～16A and 11B～16B the figure) power supply in the lift car 1 describe.
Fig. 7 is that expression is without the integrally-built figure of stern fast elevator device.As shown in the figure, 2 elevators (50A, 50B) adopt group's way to manage (mode that 2 elevators are carried out integrated management as a colony) to manage.Represent in the symbol of each member that the end is the member of No. 1 elevator of expression of A, the end is the member of No. 2 elevators of expression of B.At this, only the member of No. 1 elevator described, and omitted explanation to the member of No. 2 elevators.In addition, in the member of No. 1 elevator, the member that has been illustrated in Fig. 1 adopts same-sign to represent, omits repeat specification at this.Below take No. 1 elevator as main, the integral structure of elevator device shown in Figure 7 is described.
In elevator device (elevator device of No. 1 elevator), lift car 1A and bob-weight 48A link by main hoist cable (rope) 47A, main hoist cable 47A drives by rope sheave (sheave) 46A and pulley (pulley) 48A, and lift car and bob-weight are moved up and down.
Rope sheave 46A drives rotation by electrical motor 45A, and electrical motor 45A carries out variable speed drive (VSD) by the inverter in the elevator control gear 44A.Elevator control gear 44A, electrical motor 45A etc. are arranged on the Machine Room that is positioned at the building the superiors.
As illustrated in fig. 1, the various electrical equipments of lift car 1A are accepted power supply from car electric supply installation 3A (being made of storage battery 34 and power converter 32,33,36 and accumulator control device 35).The electrical equipment of air conditioner 11A etc. and car electric supply installation 3A are carrying out suitable action as the car of " car power control unit " under with the control of Power Control Unit 2A.
When the charging of the storage battery 34 in car electric supply installation 3A, the voltage transformer 31A by the lift car side and the voltage transformer 23A of hoist trunk side carry out electromagnetic coupled and come electric energy transmitting.The power conversion unit 24A of hoist trunk side is made of changer 21 and the inverter 22 of Fig. 1, and the power conversion that is used for the building side is high-frequency alternating current.In addition, the control information that sends from elevator control gear 44A to lift car sends by radio communication device 43A (control setup side) and 42A (lift car side).Because the stroke of hoist trunk is more than the 400m, so adopt the radio communication device that can between this distance, send.
Described radio communication for example also can adopt multi-hop (multi-hop) formula wireless communication system.Multi-hop formula wireless communication system is by the base station take IEEE802.15.4 as representative, a plurality of repeater station or the wireless network that a plurality of terminal station was consisted of that is connected with sensor, on the wall by above-mentioned a plurality of wireless communications stations being arranged on elevator lifting channel Y1 etc., can carry out independently radio communication and data and send.In addition, according to the length of the stroke of hoist trunk Y1, also can adopt sensor in the elevator lobby that is arranged on hoist trunk Y1 and each floor to carry out in-plant radio communication and replace multi-hop formula wireless communication system.
In addition, in the elevator lobby of each floor, be provided with temperature sensor 601,602 ..., 605, be used for the temperature of each floor is measured.The temperature data of this each floor sends to elevator control gear 44A by the wireline communication networks such as local area network (Local Area Network) of the elevator lobby of not shown each floor of binding, and by being wirelessly sent to car Power Control Unit 2A.

The 3rd embodiment
The instruction diagram of Figure 10 and Figure 11 control method that to be the power control apparatus of expression by the related lift car of the 3rd embodiment of the present invention regulate the output of electrical equipment (illumination equipment and electronic guiding device) in the air conditioner car in addition.
The two adjusting control of illumination equipment 12 and electronic guiding device 14 is by the car usefulness Power Control Unit 2 interior enforcements as " car power control unit " of the present invention.Come the output adjusting method of illumination apparatus and electronic guiding device to describe (suitably with reference to Fig. 1 etc.) referring to Figure 10 and Figure 11.
Figure 10 represents to regulate the car of output of illumination equipment and electronic guiding device with the structure of Power Control Unit 2.The output of the air conditioner 11 shown in the first embodiment of its basic structure and Fig. 2 is regulated identical.That is, by the output command that cage illumination output command setting section 220 is set cage illumination, regulate part 221 regulation output instructions by the illumination output command.At this, output command is regulated according to the regulated quantity that illumination output command regulated quantity arithmetic section 224 calculates.Illumination output command after illumination control command conversion fraction 222 will be regulated is transformed to the illumination control command.The illumination control command is sent to the control part of the illumination equipment in the lift car, controls the output of illumination equipment according to this control command (come from adjusting after output command).
At this, illumination equipment 12 is assumed to and basically uses LED (light-emitting diode) illumination.The LED illumination can be regulated illumination and carry out easily switch etc. by power regulation easily.Although there is the problem of aspect in service life in the fluorescent lamp of converter type, it can regulate illumination to a certain extent by power regulation.
The illumination output command is regulated mode decision part 223 according to the outside light quantity (detecting by illuminance transducer in the car of Fig. 1 18) in patronage, the car in the predictor of the residual quantity of electricity accumulation of storage battery, residual quantity of electricity accumulation, the car, judges whether to need to implement the adjusting of illumination output command.Regulating details that judgement that mode decision part 223 carries out processes by the illumination output command will be below describe with reference to the diagram of circuit of Figure 11.The judged result that the illumination output command is regulated mode decision part 223 is sent to illumination output command regulated quantity arithmetic section 224.When enforcement output is regulated in illumination output command regulated quantity arithmetic section 224, identical with the occasion of air conditioner according to residual quantity of electricity accumulation and predictor thereof, calculate adjustment factor or regulated quantity, and its result is sent to illumination output command adjusting part 221.When not implementing output and regulate, adjustment factor or regulated quantity as zero, and are sent to illumination output command adjusting part 221 with its result.
Electronic guiding device 14 is the devices at guide rail guiding (guide) lift car 1, and it is installed on the car frame of lift car 1 (schematically representing with symbol 14A in the entire system constructional drawing of Fig. 7).Electronic guiding device 14 has these 2 types of the electronic guiding device of guide boot formula (device that is sliding between the guide rail) and the electronic guiding devices of guide roller formula (being provided with roller between guide rail), DYN dynamic guiding device as power supply, before be the guiding device of electromagnetic levitation type, and the latter uses actuator to form electric structure, so that the pressing force between guide rail and the roller is regulated.Above-mentioned two types all have the effect that can reduce to vibrate with noise.
The structure that the output of electronic guiding device 14 is regulated and the adjustment structure of illumination are identical.Below simply the flow process of control structure is described.
At first, set by the output command of 225 pairs of electronic guiding devices 14 of output command setting section, when needs were regulated, output command was regulated part 226 and is carried out the adjusting of output command.Output command after control command conversion fraction 227 will be regulated is transformed to control command, and this control command is sent to electronic guiding device 14.Regulate the output adjusting that mode decision part 228 judges whether to implement electronic guiding device 14 by output command, when implementing to regulate, by output command regulated quantity arithmetic section 229 computing adjustment factor or regulated quantitys.The adjustment factor that calculates or regulated quantity send to output command and regulate part 226, and output command is regulated part 226 and is worth to come the regulation output instruction according to this.The input message that the output command of electronic guiding device 14 is regulated mode decision part 228 is the interior patronage of residual quantity of electricity accumulation, its predictor, car and the car motoring condition information of storage battery.The input message of output command regulated quantity arithmetic section 229 is residual quantity of electricity accumulation and the predictor thereof of storage battery.
The diagram of circuit that the judgement of Figure 11 when to be expression by illumination output command shown in Figure 10 regulate mode decision part 223 and electronic guiding device output command and regulate output that mode decision part 228 judges whether to implement illumination equipment 12 and electronic guiding device 14 and regulate processed.Referring to the diagram of circuit of Figure 11, the treatment scheme of illumination output command shown in Figure 10 being regulated mode decision part 223 and electronic guiding device output adjusting mode decision part 228 describes.
In the diagram of circuit of Figure 11, the illumination output command is regulated mode decision part 223 (electronic guiding device output command is regulated mode decision part 228) and is judged that at first whether the residual quantity of electricity accumulation of storage battery is less than threshold value 3 (step ST40).When being judged as greater than threshold value, judge that further whether the residual quantity of electricity accumulation predictor is less than threshold value 4 (step ST41).When if predictor also is judged as greater than threshold value (step ST41 "No"), then is judged as the output of not implementing illumination equipment 12 and electronic guiding device 14 etc. and regulates (step ST42).
On the other hand, if the residual quantity of electricity accumulation of storage battery is less than threshold value 3 (step ST40 "Yes"), when perhaps this predictor is judged as less than threshold value 4 (step ST41 "Yes"), regulates mode decision part 223 by the illumination output command and judge according to the detected value of load cell whether the seating capacity in the lift car 1 is zero (step ST43).When if patronage is zero in the car (step ST43 "Yes"), then according to the residual quantity of electricity accumulation of storage battery 34 or the output (step ST44) of its predictor attenuating car intraoral illumination.
On the other hand, regulate mode decision part 228 by electronic guiding device output command and further judge whether lift car 1 is in motoring condition (step ST45), if when being in motoring condition (step ST45 "Yes"), the output (step ST46) of then lowering electronic guiding device 14 according to residual quantity of electricity accumulation or its predictor of storage battery.If when being in halted state, not implementing the output of electronic guiding device 14 and regulate (step ST47).
In addition, when the residual quantity of electricity accumulation of storage battery 34 is in not enough state, can cause the unnecessary waste of electric energy owing to throw light in also to lift car when passenger lift car 1 in is zero, so preferably according to residual quantity of electricity accumulation appropriate control is carried out in output.Equally, when not having the passenger in lift car, the vibration that makes electronic guiding device 14 actions exceedingly suppress car also can cause the unnecessary waste of electric energy, so preferably according to residual quantity of electricity accumulation output is carried out the control of appropriateness.
By detecting the number in the lift car, when number is zero, according to residual quantity of electricity accumulation the output of illumination and electronic guiding device is controlled, can in the situation that can not bring adverse effect to elevator passenger, reduce the consumption of residual quantity of electricity accumulation.Therefore, storage battery is not easy to occur the situation of charge capacity deficiency.By implementing above-mentioned control, can further reduce the capacity that is installed in the storage battery in the lift car.
When seating capacity is non-vanishing in car (step ST43 "No"), judge that whether outside light quantity in the car that illuminance transducer 18 detects in the car of Fig. 1 is greater than threshold value 10 (step ST48).When externally light quantity is greater than threshold value 10 (step ST48 "Yes"), owing to can reduce the output of car intraoral illumination, so lower this output (step ST49) according to residual quantity of electricity accumulation or its predictor of storage battery.When externally light quantity is less than threshold value 10 (step ST48 "No"), (step ST50) do not regulated in the output of facilities and equipments.
Because also can control illumination in the lift car according to the size of extraneous light this moment, so can reduce the consumption of the residual quantity of electricity accumulation of storage battery.In addition, having extraneous light to enter occasion in the lift car for example is that the wall of lift car is made by glass, and hoist trunk is positioned at the occasion of outside, building (building is outside).Can list sightseeing elevator etc.
The 4th embodiment
Figure 12 and Figure 13 are the diagram of circuits of the control flow of the power control apparatus of expression by the related lift car of the 4th embodiment of the present invention when stopping to power from storage battery 34, when being illustrated respectively in the residual quantity of electricity accumulation deficiency of storage battery 34, stop from storage battery 34 to various electrical equipments 11～16 (with reference to Fig. 1 etc.) control flow (Figure 12) when powering, and the control flow (Figure 13) when when emergent stopping, stopping to power from storage battery.
Figure 12 and Figure 13 only represent respectively to regulate and use building power supply etc. can't deal with problems by the output of car electrical equipment, and have to stop electrical equipment 11～16 o'clock, sequence control so that the most suitably the order of (this moment suitably refer to consider from secure context the most suitable) stops electrical equipment with respect to the passenger, this control is implemented with Power Control Unit 2 by car.
In the diagram of circuit of Figure 12, car judges at first that with Power Control Unit 2 whether the residual quantity of electricity accumulation of storage battery 34 is less than threshold value A (step STA01).At this moment, if when being judged as greater than threshold value (step STA01 "No"), then waiting until and judge when processing (step STA02) next time, again return the processing of step STA01, to carry out threshold ratio.
At this, the less value of threshold value when threshold value A is set to than the output adjusting of electrical equipment.When the situation of very serious residual quantity of electricity accumulation deficiency has occured, just can implement this and stop handler.In residual quantity of electricity accumulation during less than threshold value A (step STA01 "Yes"), when the situation of very serious residual quantity of electricity accumulation deficiency has namely occured, at first stop from storage battery 34 to lift car air conditioner 11 power supplies in 1 or stop the action (step STA03) of air conditioner 11.
Afterwards, judge that with Power Control Unit 2 whether the residual quantity of electricity accumulation of storage battery 34 is less than threshold value B (step STA04) by car.Be (step STA04 "No") during greater than threshold value B in the result who judges, when judge processing next time by the time (step STA05), again return the processing of step STA04, to carry out threshold ratio.Car position telltale 13 (indicating device) in the result who judges is (step STA04 "Yes") during less than threshold value B, stops from from storage battery to lift car is powered or is stopped the action (step STA06) of car position telltale 13.
After this, judge that whether the residual quantity of electricity accumulation of storage battery 34 is less than threshold value C (step STA07).Be (step STA07 "No") during greater than threshold value in the result who judges, when judge processing next time by the time (step STA08), again return the processing of step STA07, to carry out threshold ratio.Be (step STA07 "Yes") during less than threshold value C in the result who judges, the illumination equipment 12 that stops from storage battery 34 to lift car in 1 is powered the perhaps action of lighting-off device 12 (step STA09).
After this, judge that whether the residual quantity of electricity accumulation of storage battery 34 is less than threshold value D (step STA10).Be (step STA10 "No") during greater than threshold value D in the result who judges, when judge processing next time by the time (step STA11), again return the processing of step STA10, to carry out threshold ratio.Be during less than threshold value D in the result who judges, (step STA10 "Yes") stops to power from storage battery 34 to cage door drive or stops the action (step STA12) of cage door drive.
Stop perhaps to stop the action of this electrical equipment to various electrical equipments 11～16 power supplies according to above sequential stages ground, but until the residual quantity of electricity accumulation vanishing still keep to intercom phone 16 power supplies.This be because, air conditioner 11 and car position telltale in the lift car 1 are not indispensable, although can affect traveling comfort, compare with other equipment, its effect or acceptable are so stop electrical equipment according to said sequence.12 pairs of illumination equipments guarantee that the safety (considering from the angle of delinquency prevention) in the lift car is essential, so till really can not keeping to residual quantity of electricity accumulation, keep to the power supply of illumination equipment 12.And, to compare with illumination equipment 12, the actuating device of elevator cab door is even more important, if elevator door can't carry out switch, the passenger then can occur and be closed in situation in the lift car, therefore, the power failure of the actuating device of elevator cab door is arranged in order on penult.
Last is stopped power supply is for intercom phone 16 externally and in the car of getting in touch with between in the lift car 1, because under any situation, in order to carry out safety verification, all be necessary to understand the situation in the lift car, so be necessary the power supply to intercom phone in the car 16 is maintained at last.
As mentioned above, by according to the order that stops shown in Figure 12 various electrical equipments 11～16 being quit work, even when the such worst case of residual quantity of electricity accumulation wretched insufficiency having occurred, also can guarantee passenger's safety.
Figure 13 is identical with Figure 12, stopping sequentially of electrical equipment during expression residual quantity of electricity accumulation wretched insufficiency, different from Figure 12 is, Figure 12 represents be under normal circumstances (when elevator is in operation conditions) stop order, and Figure 13 represents be such as elevator because of occured earthquake etc. carried out emergent stopping etc. in emergency circumstances stop order.Diagram of circuit referring to Figure 13 describes.
In the diagram of circuit of Figure 13, car judges at first with Power Control Unit 2 whether lift car 1 is in emergent stopping state (step STB01).Being judged as (step STB01 "No") when not being in the emergent stopping state, process according to diagram of circuit shown in Figure 12.Be judged as (step STB01 "Yes") when being in the emergent stopping state, judge that whether the residual quantity of electricity accumulation of storage battery 34 is less than threshold value F (step STC01), be (step STC01 "No") during greater than threshold value F in the result who judges, the armed state (step STC02) such as before judging, enter next time, after this, return the processing of step STC01, to carry out threshold ratio.If the result who judges is (step STC01 "Yes") during less than threshold value F, stop from storage battery 34 to lift car car position telltale 13 (indicator) power supply in 1, the action of car position telltale 13 is stopped (step STC03).
Afterwards, judge that whether the residual quantity of electricity accumulation of storage battery 34 is less than threshold value G (step STC04), be (step STC04 "No") during greater than threshold value G in the result who judges, the armed state (step STC05) such as before judging, enter next time, after this, return the processing of step STC04, to carry out threshold ratio.If the result who judges be (step STC04 "Yes") during less than threshold value G, stop to power from storage battery 34 to cage door drive, perhaps stop the action (step STC06) of cage door drive.
After this, judge that whether the residual quantity of electricity accumulation of storage battery 34 is less than threshold value H (step STC07), be (step STC07 "No") during greater than threshold value H in the result who judges, the armed state (step STC08) such as before judging, enter next time, after this, return the processing of step STC07, to carry out threshold ratio.If the result who judges be (step STC07 "Yes") during less than threshold value H, the air conditioner 11 that stops from storage battery 34 to lift car in 1 is powered, and the action of air conditioner 11 is stopped (step STC09).
After this, judge that whether the residual quantity of electricity accumulation of storage battery 34 is less than threshold value I (step STC10), be (step STC10 "No") during greater than threshold value I in the result who judges, the armed state (step STC11) such as before judging, enter next time, after this, return the processing of step STC10, to carry out threshold ratio.If the result who judges be (step STC10 "Yes") during less than threshold value I, stop from storage battery 34 to lift car illumination equipment 12 power supplies in 1, perhaps make the action of the interior illumination equipment 12 of lift car 1 stop (step STC12).
In the diagram of circuit of above-mentioned Figure 13, identical with the situation of Figure 12, continue from storage battery 34 to car in intercom phone 16 power supplies, until the residual quantity of electricity accumulation of storage battery 34 is zero.That is to say that the intercom phone 16 in the lift car 1 is with always perseveration, to the last.When elevator emergency stops when emergent stopping (elevator floor midway), the passenger may appear by the situation of temporary close in lift car 1, for the temperature in the lift car 1 is remained on suitable temperature, preferably the order that stops with air conditioner 11 moves backward.In addition, owing to temporarily can not make the door action of lift car 1, therefore can stop to power to elevator door in the stage early.And, even because the door of lift car 1 is also wanted consumed power under the state of closing, so by stopping power supply, can play the effect of the consumption that reduces residual quantity of electricity accumulation.So, because the situation during emergent stopping is different with situation about normally stopping, so, process by the order that stops that employing is different from when normal, can stop order equipment is stopped with more suitable with respect to the passenger.
The 5th embodiment
Figure 14 to Figure 16 is the instruction diagram of the power control apparatus of the related lift car of the 5th embodiment of the present invention.In the 5th embodiment, storage battery 34 is made of the 1st storage battery and these two storage batterys of the 2nd storage battery as main storage battery, when the residual quantity of electricity accumulation as the 1st storage battery of main storage battery occurs when not enough, by the 2nd storage battery power supply as subsidiary battery.Figure 14 is the diagram of block of the power supplyl controlling structure of the above-mentioned lift car of expression.
In Figure 14, adopt the title of part of the symbolic representation identical with the first embodiment shown in Figure 1 and function and part shown in Figure 1 identical.Be with the difference of the first embodiment, further increased the control setup 35S of the 2nd storage battery 34S, the 2nd storage battery 34S and to the DC/DC changer 33S of the 2nd storage battery 34S.
The same with main storage battery 34, the 2nd storage battery 34S powers to the electrical equipment in air conditioner 11 lift cars such as grade by DC/DC changer 33S.In addition, because the output of the output of main storage battery 34 and the 2nd storage battery 34S all is connected on the dc bus between DC/DC changer 33S and the inverter 36, so can be charged to the 2nd storage battery 34S by the building power supply by DC/DC changer 32 from the voltage transformer 31 of lift car side equally.
Car is connected with the main storage battery control setup 35 of main storage battery 34 and the 2nd accumulator control device 35S of the 2nd storage battery 34S by order wire with Power Control Unit 2, thereby can respectively to this device sending controling instruction, perhaps state of a control be monitored.
The effect of the 2nd storage battery 34S is to use as subsidiary battery when deficiency appears in the residual quantity of electricity accumulation of main storage battery 34.For the control scale increases, the 2nd storage battery 34S preferably uses the little storage battery of volume ratio main storage battery 34 as far as possible.And on the other hand, as the 2nd storage battery 34S, choice for use has the storage battery of fast charging and discharging performance.During at the floor that can charge, the 2nd storage battery 34S carries out fast charge with the charge volume that increases sharply at elevator parking, under steam and then discharge when resting in other floor.
The 2nd storage battery 34S is arranged to charge rapidly and can within the long as far as possible time, discharges, thereby can play the effect of the consumption of the residual quantity of electricity accumulation that reduces main storage battery 34.Carry out the 2nd storage battery 34S of fast charging and discharging as needs, be fit to use double layer capacitor and lithium ion battery etc.On the other hand, main storage battery 34 will discharge (be called again and recycle) in regulation long-time, so need to have the characteristic different from the 2nd storage battery 34S after the long-time charging of having carried out regulation.In addition, in the ordinary course of things, if the storage battery of above-mentioned recycling-type carries out the charging action of short time midway in discharge, especially with the action of charging of large electric current, can cause reduce service life, perhaps might damage storage battery, therefore preferably avoid charging in discharge midway.
The 2nd storage battery 34S as implied above, as to use by being provided as subsidiary battery, the capacity that can further be reduced in is set the capacity with main storage battery 34 of surplus capacity.Because the 2nd storage battery 34S can carry out fast charge and discharge halfway, so its capacity can be set the capacity less than the reduction capacity of main storage battery 34 for, thereby can reduce overall size and the weight of storage battery.
Figure 15 is the diagram of circuit of the control sequence of expression the 2nd storage battery 34S.Describe referring to diagram of circuit shown in Figure 15 pattern when having used the 2nd storage battery.
At first, whether the residual quantity of electricity accumulation of judging main storage battery 34 with Power Control Unit 2 by car less than threshold value 5 (step ST61), afterwards, judges that whether the predictor of residual quantity of electricity accumulation of main storage battery 34 is less than threshold value 6 (step ST62).During all greater than its separately threshold value (step ST61 "No", ST62 "No"), the residual quantity of electricity accumulation that then is judged as main storage battery 34 is enough, thereby does not make the 2nd storage battery 34S action (step ST63) at both.Any one is judged as (step ST61 "Yes" when satisfying above-mentioned condition and when the two, perhaps step ST62 "Yes"), enter the 2nd storage battery pattern that makes the 2nd storage battery 34S action (zone that is surrounded by dotted line shown in the step ST64).
At this, at first standby floor (lift car finishes the floor of the rear standby of service) is set as the floor (step ST65) that is provided with to the electric supply installation of lift car power supply.Therefore, a certain floor that the car that finishes to be in after the service readiness for action is being provided with electric supply installation always carries out standby, can charge to the 2nd storage battery 34S in standby.After this, judge whether car is in halted state, and judge car position whether consistent with the floor that is provided with electric supply installation (step ST66).Be judged as (step ST66 "Yes") when satisfying condition, can to the 2nd storage battery 34S charging, carrying out fast charge (step ST67) by building side power supply 20 to the 2nd storage battery 34S.
Be judged as (step ST66 "No") when not satisfying condition, entering the pattern that makes the 2nd storage battery 34S discharge.At first, the consumed power (step ST68 and ST69) of control air conditioner 11 and illumination equipment 12.On this basis, make the 2nd storage battery 34S control discharge (step ST70) with constant potential.For main storage battery 34, the higher limit of discharge current is set, to limit its discharge current (step ST71).
Its result, the difference part between the consumed power of the discharge power of main storage battery 34 and car power apparatus 11～16 is provided by the 2nd storage battery 34S.Concrete method is, when the consumed power of car power apparatus 11～16 during greater than the discharge power of main storage battery 34, and because of underproof, the voltage drop of dc bus (dc bus between DC/DC changer 33S and the inverter 36).Because the 2nd storage battery 34S controls in the mode of constant potential control, so the 2nd storage battery 34S carries out discharging action with the power of the part of covering the shortage, make thus the supply and demand of electricity reach balance.
When the discharge of the 2nd storage battery 34S output is not enough (in principle, it is not very large storage battery that the 2nd storage battery 34S selects capacity and horsepower output), because the voltage of dc bus is in lower state all the time, so when detecting this situation (step ST72), for electric power is balanced, further control the consumed power of air conditioner 11 and illumination equipment 12 (by the operation output of the further control convenience of output adjustment factor.The adjusting of air conditioner is regulated part 202 by the air-conditioning instruction of Fig. 2 and is implemented) (step ST74).When DC bus-bar voltage does not descend, keep current state (step ST73).
As mentioned above, when the residual quantity of electricity accumulation of main storage battery 34 has occured when not enough, on the one hand by controlling so that the 2nd storage battery 34S charges continually and discharges, control the consumed power of air conditioner 11 and illumination equipment 12 these electrical equipments on the one hand, thereby can reduce the consumption of the residual quantity of electricity accumulation of main storage battery 34.Its result can reduce capacity and the weight of storage battery integral body.
Figure 16 is illustrated under the situation that makes the 2nd storage battery 34S action, when the diagram of circuit of the processing sequence when not enough has occured in action for the capacity of the 2nd storage battery 34S.
In Figure 16, identical symbolic representation is adopted in the processing identical with Figure 15, and omits its repeat specification at this.Below only the processing different from the diagram of circuit of Figure 15 described.
Discharge with constant potential control at the 2nd storage battery 34S, main storage battery 34 is set under the state that the discharge current higher limits discharge (step ST70 and ST71), if (step ST82) when not enough appearred in the residual quantity of electricity accumulation of the 2nd storage battery 34S halfway, car uses Power Control Unit 2 to remove the discharge current higher limit of main storage batterys 34, and in the mode of constant potential control it is controlled (step ST84).Its result is responsible for powering to the electrical equipment of air conditioner 11 and illumination equipment 12 etc. by main storage battery 34.After this, because lift car 1 enters readiness for action, and move to the floor standby that is provided with to the electric supply installation of lift car 1 power supply, thus can implement fast charge to the 2nd storage battery 34S, thus can make the 2nd storage battery 34S again discharge to rescue the state of main storage battery 34.
The 6th embodiment
Figure 17 to Figure 20 is the instruction diagram of the power control apparatus of the related lift car of the 6th embodiment of the present invention, the 6th embodiment is not in order to realize without the stern fast elevator, but for by reducing the electric current of stern fast power supply, reduce diameter or the quantity of electric wireline.
Referring to Figure 17 to Figure 20 the structure action of the elevator device of employing light weight stern fast is described.
The advantage of this elevator device is to pass through the light weight stern fast, ceaselessly powers (but, owing to the capacity that has reduced electric wireline, so delivery is restricted) from the building power supply, compares with the situation without stern fast, can reduce the capacity of storage battery.
And, below the 6th embodiment of explanation between existing elevator with stern fast and of the present invention without the stern fast elevator between, although can not realize without stern fast, but owing to can alleviate the weight of stern fast, and can reduce again the capacity of the storage battery 34 that is installed on the lift car 1, therefore can make whole system realize lightweight.
Figure 17 has represented to adopt the integral structure figure of the elevator device of light weight stern fast.Because Figure 17 is roughly the same with the basic structure of the second embodiment shown in Figure 7, therefore, the identical identical symbolic representation of part employing, and have identical title and function.
Both differences are that the 6th embodiment beyond the 70B, has also been cancelled the electric supply installation (23A, the 24A of Fig. 7) to the lift car power supply that is arranged on the hoist trunk side except having set up light weight stern fast 70A.
In use shown in Figure 17 in the elevator device of light weight stern fast owing to can ceaselessly accept by stern fast the Power supply of building side, therefore, need to not arrange to the electric supply installation of lift car power supply in the hoist trunk side.
And, as shown in figure 17, powered to elevator control gear 44A by building power supply 20, and elevator control gear 44A is connected with car electric supply installation 3A by light weight stern fast 70A, thereby can power to lift car by elevator control gear 44A, light weight stern fast 70A and car electric supply installation 3A from building power supply 20.
Figure 18 is the diagram of block that expression has adopted the power control section of lift car of the elevator device of light weight stern fast to divide.Because its structure is roughly the same with the first embodiment shown in Figure 1, therefore, the identical identical symbolic representation of part employing, and have identical title and function.
Both differences are, the 6th embodiment has also been cancelled the electric supply installation to the lift car power supply that is arranged on the hoist trunk side (Fig. 1 23,22,21) except having set up light weight stern fast 70.Implemented with Power Control Unit 2 by car to the charging that storage battery 34 carries out by light weight stern fast 70 from the building power supply.
Figure 19 is the diagram of circuit of power control flow of the storage battery 34 of the expression elevator device that adopted the light weight stern fast.Referring to the diagram of circuit of Figure 19, the action with Power Control Unit 2 describes to car shown in Figure 180.
At this, judge at first whether current point in time is the charging duration section (step ST90) of storage battery 34.The charging duration section of storage battery 34 is set in the lower time period of frequency of utilization of evening and elevator in principle, for example is set to from 23 o'clock to 7 o'clock time period.If when current point in time is the charging duration section of storage battery 34, enter the charge mode that storage battery 34 is charged by stern fast.When car is judged as charge mode with Power Control Unit 2 (step ST91), by stern fast with the electric current below the specified value to storage battery charge (step ST92).Owing in order to make stern fast realization lightweight reduce the diameter of electric wireline, perhaps reduced the radical of electric wireline, so need to charge to storage battery with little electric current.The specified value that electric current is limited determines according to the current capacity of electric wireline.Continue storage battery 34 is charged until it reaches complete charge condition (step ST93), reach complete charge behind the complete charge condition, lift car enters readiness for action (step ST94).
When current point in time was beyond the charging duration section of storage battery, storage battery 34 entered discharge mode.When car is judged as discharge mode with Power Control Unit 2 (step ST95), control storage battery 34 (step ST96) with the constant potential mode.At this moment, mainly powered to car electrical equipment 11～16 by storage battery 34, the building power supply of powering by stern fast is accessory feed.The reason of the building power supply being arranged to accessory feed is that after the electric wireline in the stern fast dwindled, its current capacity was restricted.
When the consumption power of the electrical equipment 11～16 in the lift car 1 is very large, because the delivery of building side power supply 20 is provided with the upper limit, so by storage battery 34 as main electric supply installation, if but consumed power hour, in order to preserve the residual quantity of electricity accumulation of storage battery 34, preferably building side power supply is used as main electric supply installation.Therefore, preferably being arranged to provides certain power (all the time supply power suitable with higher limit) all the time by building side power supply 20, and remaining insufficient section is powered by storage battery 34.When the response to power supply of building side power supply is very fast (response of building side power supply is very fast in general situation), by storage battery 34 being carried out constant potential control, then can realize above-mentioned method to set up.
In order to lower the capacity of storage battery 34, can adopt above-mentioned being used for to regulate method without the output of the electrical equipment of stern fast elevator device.Therefore, according to the residual quantity of electricity accumulation of storage battery 34, enforcement is used for regulating method (Fig. 3 to Fig. 6 and Figure 10 to Figure 13) without the output of the electrical equipment of stern fast elevator device.
Situation when Figure 20 represents that the control flow chart according to the storage battery of the elevator device of use light weight stern fast shown in Figure 19 carries out the charging of storage battery and discharge.
The intraday situation of change of the electric current that flows through in the electric wireline of Figure 20 (a) expression from stern fast.In the diagram of curves of Figure 20 (a), transverse axis represents the time, and its time length is 1 day.The longitudinal axis represents to flow through the interior current value (if when using many electric wireline, being the aggregate value of each electric current) of electric wireline in the stern fast.When current value be on the occasion of the time, the expression electric current just flow to lift car from control panel.
Solid line among Figure 20 (a) represents the characteristic of the electric current of actual flow.It is roughly fixed value.This fixed value is corresponding with the higher limit that determines according to the current capacity of the electric wireline in the stern fast.That is to say no matter storage battery is in charge condition or is in discharge regime, provides the electric current suitable with higher limit by the building power supply, can lower thus the property of storage battery.
Dotted line among Figure 20 (a) represents the load current value of air conditioner.Because in the situation of common stern fast, the electric current that flows in stern fast is determined by the current sinking of the electrical equipment of lift car, so the electric current that flows may surpass the electric current shown in the dotted line, therefore need to use thicker electric wireline or the many electric wireline of diameter, but according to the 6th embodiment of the present invention, because also use simultaneously storage battery, thus actual current value can shown in Figure 20 (a), be reduced, thus can cut down the electric wireline in the stern fast.Therefore, can make the stern fast lightweight.
Figure 20 (b) expression is installed in the intraday situation of change of the electric current of the storage battery on the lift car.Transverse axis among the figure represents the time, and its time length is 1 day, and the longitudinal axis represents the electric current of storage battery.Discharging on the occasion of expression of electric current, negative value represents to charge.Be in charge condition from 23 in evening to morning till 7, be in discharge regime till 23 from 7 of mornings to evening.
The intraday situation of change of the current sinking of the electrical equipment in Figure 20 (c) expression lift car.Evening, the consumed power of the electrical equipment in the lift car is little, and (for the ease of understanding, the consumed power among the figure was zero during idle periods.Even under actual conditions, aviation value that also can forecast consumption power is very little), but by day, along with the increase of elevator passenger and the rising of temperature, the consumption power of air conditioner etc. also rises, and within the time period in afternoon, current sinking will further increase especially at noon.In existing elevator device, because the current sinking of the car electrical equipment shown in Figure 20 (c) directly flows through stern fast, thus need thicker electric wireline (perhaps many electric wireline), thus the problem of stern fast preponderance produced.Compare with Figure 20 (a), can know that the electric current that flows through stern fast reduces, thereby can realize the lightweight of stern fast.
The discharge current of storage battery 34 also is like this, in the mode without stern fast, the electric current that storage battery 34 must provide the current sinking of the electrical equipment 11～16 in the lift car 1 with Figure 20 (c) to equate, if and adopt above-mentioned the 6th embodiment, then because can power from stern fast, so can shown in Figure 20 (b), reduce the discharge current of storage battery 34.Therefore, can lower the necessary capacity of storage battery.
As mentioned above, power control apparatus according to lift car of the present invention, not only can realize elevator without stern fast, perhaps realize the lightweight of stern fast, but also the significant design item can realize without stern fast and stern fast lightweight the time, namely can reduce to be installed in the capacity of the storage battery on the lift car, can save the unnecessary part in the consumed power of the electrical equipments such as interior environment system and illumination equipment, thereby can suppress consumed power.
And above-mentioned car can be arranged to all realize by software with the function of each construction module that Power Control Unit 2 has, also can be arranged to one of them part and be realized by hardware.For example, consist of the car air-conditioning instruction setting section 201 of power control apparatus 2, part 202 is regulated in the air-conditioning instruction, air-conditioning control command conversion fraction 203, master mode judgment part 204, air-conditioning instruction regulated quantity arithmetic section (the air conditioner function is regulated pattern) 205, data in air-conditioning instruction regulated quantity arithmetic section (building electric source modes) 206 and the storage battery control command setting section (building electric source modes) 207 are processed and can be arranged to realize on computers by one or more program, also can be arranged to one of them part and be realized by hardware.
