In addition, powered to elevator hall call device 101~10n and the lift car call button in the lift car 7 71 of each floor (1~n layer) by elevator lobby and lift car power pack 22.
Communicating by letter between the elevator hall call device 101~10n of elevator control gear 2 and each floor undertaken by the elevator lobby communicator 131~13n in the elevator lobby of communication control part 23 and each floor.Be provided with the lift car call button 71 that is constituted by destination floor call button, elevator door opening-closing button, lift car communicator and read out instrument etc. in the lift car 7, with communicating by letter and power and undertaken by stern fast 72 between the lift car.
Fig. 2 is the constructional drawing of the elevator hall call device 100 of each floor in the power saving apparatus of the related elevator of the first embodiment of the present invention.In elevator hall call device 100, elevator lobby call button 15, read out instrument 16 and elevator lobby communicator 13 are by 11 controls of elevator lobby control part.In addition, to elevator hall call device 100 power supplies the time, (121~12n) of Fig. 1 is switched on or switched off to control the power supply that comes from elevator lobby and lift car power pack 22 (Fig. 1) by making elevator lobby power switch 12.Elevator lobby communicator 13 is connected (ON)/disconnection (OFF) control by communication switch 14 by elevator lobby control part 11.Elevator lobby control part 11 is controlled each switch from elevator lobby control circuit 111 by switching control section 112.
Be provided with storage unit 17 in the elevator hall call device 100, even and be configured to have stopped disconnecting elevator lobby power switch 12 under the state from the power supply of elevator lobby and lift car power pack 22 (Fig. 1), elevator hall call device 100 also can respond the operation of elevator lobby call button 15.
In elevator lobby control part 11, by storage unit 17 and power generation part 18 are set, even under elevator lobby power switch 12 cut states, elevator lobby control part 11 also can keep minimal function.Be specifically, when elevator lobby call button 15 has been operated, in elevator hall call device 100, the oneself is carried out in this operation and keep (login), make the source switch 113 of elevator lobby power switch 12, communication switch 14 and read out instrument 16 connect (turn on) simultaneously.Thus, the Presentation Function that transmits the read out instrument 16 of function that elevator lobby calls out and elevator lobby to elevator control gear 2 (Fig. 1) can be returned to and identical at ordinary times state.
Storage unit 17 is configured to by charging from the power supply of elevator lobby and lift car power pack (control main power source) 22, but owing to be provided with power generation part 18, so can reduce from the electric power of main power source supply.As power generation part 18, the various power generation assemblys such as device of solar generating that for example can adopt the light that utilizes elevator lobby to generate electricity.
In addition, have and to detect the function whether lift car 7 has arrived this elevator lobby by lift car detecting device 19.Lift car detecting device 19 for example can be made of the member that the contact switch of connecting when the elevator lobby door is opened etc. needs to expend electric power hardly.
Fig. 3 represents the treatment scheme of section at one's leisure when entering dormant state of the first embodiment of the present invention.At this, be that example describes with lift car 7 in the occasion of 1 layer of standby.In step 301, be judged as when being in idle period, in step 302, make switch circuit controller 4 open to stop the power supply to power inverter 5, and further make the driving of elevator control gear 2 with source switch 206 disconnections of source switch 204 and Drive and Control Circuit 207, drive control part 21 is stopped.Above-mentioned each action is equivalent to the action of the power supply of rupturing capacity changer 5 and controller for transducer.When elevator is in readiness for action, stop to the power supply of winch 6.But, because power inverter 5 has the discharging resistance etc. of smooth condenser, thus though that consumption of current is compared during with operation is very little, but still can consume electric power, so by making switch circuit controller 4 open, can reach energy-conservation effect.
After this, in step 303, ((132~13n) of Fig. 1 sends the instruction of stopping to 102~10n) the elevator lobby communicator 13 of Fig. 1 from elevator control gear 2 to the elevator hall call device that does not have lift car at 2~n of standby layer by communication control part 23.After receiving this instruction, in step 304, the elevator hall call device 102~10n of 2~n layer enters dormant state.That is to say, close read out instrument 16, (122~12n) of Fig. 1 stops to power from elevator lobby and lift car power pack (control main power source) 22 to cut off elevator lobby power switch 12.And, thereby cut off communication switch 14 elevator lobby communicator 13 is stopped.
On the other hand, in the elevator hall call device 100 that has lift car at the floor of standby, read out instrument 16 is closed, but the source switch that makes elevator lobby communicator 13 is communication switch 14 keeps on-state, thereby make when elevator lobby call button 15 is pressed, can open elevator door at once, can avoid thus allowing the passenger wait for.
In the present embodiment, only make lift car remain on on-state at the communication switch 14 of the elevator lobby communicator 13 of the floor of standby, but the communication switch 14 of the elevator lobby communicator 13 of the certain floor that the possibility that also can be arranged to also to make benchmark floor passengers such as (being generally 1 layer) to occur is high remains on on-state, thus, the probability of passenger's wait time shortening improves.
Consumption of current when travelling with elevator is compared, the consumption of current of elevator hall call device is approximately 1/10th, by closing read out instrument, can further reduce consumption of current about half, though the reduction amount is small, but in number of floor levels reached tens of layers high-rise apartment building, if standby time is very long, then the size of its consumption of current also can reach the degree that can not ignore.
According to present embodiment, by further stopping the elevator lobby communicator of the floor except lift car standby floor in the elevator hall call device, the consumption of current in the time of can reducing standby can be realized energy-conservationization of elevator.
Treatment scheme when Fig. 4 represents recovering from dormant state of the first embodiment of the present invention.
The same with the occasion of Fig. 3, being in dormant state with lift car at the elevator hall call device 102~10n of 1 layer of standby and 2~n layer is that the state of step 401 is that example describes.At this, suppose in step 402 passenger of floor below going to has appearred in the k layer, this passenger has pressed the elevator lobby call button 15k of down direction.At this moment, though the elevator hall call device 10k of k layer is in dormant state, owing to be provided with storage unit 17, so elevator lobby call button 15k responds this calling at once in step 403, the response lamp of button is opened, notified its calling of carrying out of passenger to obtain accepting.In step 404, the elevator lobby control part 11k of the elevator hall call device 10k of k layer connects communication switch 14k so that elevator lobby communicator 13k recovers, and by communication control part 23 downlink call information is sent to elevator control gear 2 at the k layer.Then, in step 405, the elevator hall call device 10k of k layer connects power switch 12k, powers from elevator lobby and lift car power pack (control main power source) 22 with recovery, after this, read out instrument 16k is recovered.
At this moment, because elevator lobby communicator 13k is in dormant state, influenced by it, pressed elevator lobby call button 15k from the passenger, connect to communicator 13k, read out instrument 16k recovers and begins to show that for example lift car is in the such information of which floor, and life period is poor therebetween.But, because in step 403, after elevator lobby call button 15k was pressed, the response lamp was opened at once, made this situation of reaction so the passenger can in time grasp control setup, thereby can not have influence on service quality.
On the other hand, in elevator control gear 2, the call information from k layer elevator hall call device of response of step 403 makes drive control part 21 recover in step 407, and connects switch circuit controller 4.This move is equivalent to the recovery action of power inverter 5 and controller for transducer.
At this moment, if used insulated gate bipolar transistor (IGBT) in the on-off element that constitutes power inverter 5, if then applying voltage under the situation that does not apply bias voltage between grid and emitter-base bandgap grading, starting the arc phenomenon may take place.Therefore, be arranged to make earlier drive control part 21 to recover in the present embodiment, connect switch circuit controller 4 then.IGBT is not carrying out grid not being carried out discharging and recharging of electric charge under the state of switch motion, so the consumption of current of drive control part 21 is than usual little.Therefore, also can be arranged in drive control part 21 be stopped, but this moment drive control part 21 inside power circuit etc. in can produce energy consumption.Therefore, in order further to reduce the standby electricity consumption, be arranged to make drive control part 21 also to stop in the present embodiment.
By connecting switch circuit controller 4, smooth condenser to power inverter 5 in step 408 charges, but connect power supply smooth condenser not being applied under the voltage condition, may produce rush current and cause service life of cond and switch circuit controller to descend or damage.In order to address this problem, be provided with the initial charge circuit, so that before when connecting switch circuit controller 4, having taked applying vdc to a certain degree, connect the measure (this partial content not being illustrated in order to simplify accompanying drawing) of power supply etc. by resistance.
After this, in step 409, send the instruction that makes power inverter 5 operations after the charging that elevator control gear 2 detects smooth condenser is finished, in step 410, by drive control part 21 power inverter 5 is driven, lift car 7 is moved towards the k layer.In step 411, elevator car arrives k layer is also opened elevator door, and the passenger can take advantage of into lift car thus.
In above-mentioned each step, the occasion that enters readiness for action with the elevator hall call device 10k that does not make the k layer is compared, because elevator lobby communicator 13k is recovered, wait time can be corresponding elongated.But, from comprising the switch circuit controller 4 that is in open state is connected, with time of to need to the power supply station of power inverter 5 recovering and lift car 7 from 1 layer of shifting time that drives to the k layer of standby at interior total wait time, the recruitment of wait time is very little, so the influence that brings to the passenger is also very little.
In addition, if the standby floor that makes lift car i.e. 1 layer elevator hall call device 101 also enters dormant state, then can further reduce the standby electricity consumption, if but elevator lobby communicator 131 is stopped, then when the elevator lobby calling has appearred in the standby floor, take advantage of the recruitment of the time till the lift car big to the passenger, the influence that brings to the passenger is big.Especially, in recent years, in the elevator that the apartment is used, to be set to the situation of window a lot of for the part of elevator door for the criminal's of preventing needs, at this moment, because the visible lift car in this floor standby of passenger, so if the passenger can not take advantage of into elevator at once, make the passenger produce doubt probably or produce uneasiness and feel.Therefore, in the present embodiment, adopted the elevator hall call device 101 that does not make lift car standby floor to enter the structure of dormant state.
In the present embodiment, as shown in Figure 4, lift car is 1 layer of standby, under this state, when calling has appearred in the k layer, lift car moves to the k layer from 1 layer, after the passenger takes advantage of lift car, lift car moves to the floor that the passenger goes to from the k layer, at this moment, elevator lobby communicator 132~13n (not comprising 13k) of the elevator hall call device 102~10n of other floors (not comprising the 10k layer) is owing to be in halted state, so and do not carry out the transmission of information between the elevator control gear 2.In addition, in the present embodiment, read out instrument 162~16n (not comprising 16k) does not recover yet.Thus, at the extremely low idle period of the possibility that the passenger occurs, can further improve power savings.At this moment, even the passenger occurred, if the elevator that uses at apartment and flats, because most passengers are the resident families of these apartment and flats, so if when moving in resident family is explained the situation, then resident family can accept and do not have an awkward sensation.
In addition, when the destination floor that will go to as the passenger who takes advantage of at the k layer into elevator is in addition floor of lift car standby floor (being 1 layer in the present embodiment), can the elevator hall call device 100 of this arrival floor be recovered by lift car detecting device 19, with the situation of reply when the elevator lobby calling appears in this floor.After this, when entering the idle condition that does not have elevator-calling, enter dormant state according to flow process shown in Figure 3 again.At this moment, can be arranged to make lift car to turn back to benchmark floor (for example 1 layer), also can be arranged to make lift car directly not make it turn back to the benchmark floor in the arrival floor standby, and make the floor except lift car standby floor in 1~n layer or the elevator hall call device 100 of the floor except lift car standby floor and benchmark floor enter dormant state.
In addition, because each elevator hall call device makes the elevator lobby communicator enter dormant state after receiving the instruction of stopping, so can't accept the instruction from elevator control gear 2, but also the instruction of stopping can be arranged to comprise the instruction of stop time etc., so, can after the stop time of having passed through regulation, the elevator hall call device of each floor be recovered automatically.
