Detailed description of the invention
Referring to Fig. 1, the integral structure of elevator is described.As shown in Figure 1, elevator is moving by source power supply 101 at ordinary times.In order to tackle power failure, elevator setting has electrical storage device 103, and this electrical storage device 103 has storage battery 102, detects power failure and the detecting device 112 restoring electricity of source power supply 101 and between source power supply 101 and storage battery 102, switch the shifter 104 in electric power supply source.The signal wire (SW) 116 of shifter 104 origin self-test devices 112 is controlled.Storage battery 102 is output as direct current output, after not shown AC/DC conversion, supplies the electric power that voltage is identical with source power supply 101.Elevator also has the elevator control gear 105 of controlling elevator operation and passenger is notified etc. and accepts via signal wire (SW) 115 the elevator drive control setup 107 that elevator control gear 105 is controlled, and elevator drive control setup 107 is for controlling the driving of electrical motor 106.Elevator drive control setup 107 is controlled according to operational mode by elevator control gear 105.In addition, elevator also has the residual capacity information of the information in electric power supply source and storage battery 102 etc. is passed to the signal wire (SW) 113 of elevator control gear 105, carries out the elevator 108 of lifting by electrical motor 106 in hoist trunk, kept the counterbalanced weight (CW) 110 of balance and via signal wire (SW) 114, elevator running condition is notified to passenger's notifying device 111 (telltale, loud speaker etc.) from elevator control gear 105 by hoist cable 109 and elevator 108 from electrical storage device 103.Elevator control gear 105 also obtains the status information (speed, load etc.) of the car 108 of elevator by signal wire (SW) 114.
As shown in Figure 2, elevator control gear 105 is connected to each other with the main control unit 203 of communicator 201, memory storage 202 and the operation of control elevator.Communicator 201 is exchange message between electrical storage device 103, elevator drive control setup 107 and car 108.In addition, communicator 201 and communication external are to receive power failure information.Power failure information comprises have a power failure time opening and power failure end time.
Referring to Fig. 3, the action of elevator control gear 105 is described.
After initialization process (A100), communicator 201 checks whether inputted power failure information (A200) from outside via signal wire (SW) 204, in the time that communicator 201 is not inputted power failure information, enters and processes A400.In the time that communicator 201 has been inputted power failure information, communicator 201 is stored in the power failure information of inputting via signal wire (SW) 204 in memory storage 202 (A300).
According to the power failure time opening comprising in the power failure information being stored in memory storage 202, check whether the time opening that has a power failure is about to arrive (A400).In this inspection, be checked through the excess time having a power failure till the time opening whether at the appointed time below (T minute).In the time that be equal to or less than specified time (T minute) excess time, be judged as the time opening that has a power failure by arriving.Being judged as from having a power failure the time opening while also having certain hour, enter common operation processing (A500).
Conventionally moving in processing (A500), via required information of operation such as signal wire (SW) 114 exchange car positions such as grades and hall calls, so that service to be provided.Conventionally operation processing (A500) is the common operational mode that adopts traditional elevator control technology to control, and at this, description is omitted.Process A200 having carried out returning after a series of common operation processing (A500).
When be judged as have a power failure the time opening be about to arrive time, carry out have a power failure prepare process (A600).The details that processing (A600) is prepared in this power failure describes in aftermentioned part.
Having a power failure after generation, the detecting device 112 of electrical storage device 103 is controlled shifter 104 via signal wire (SW) 116, shifter 104 is switched to storage battery 102 by power supply from source power supply 101, and electrical storage device 103 has been switched to storage battery 102 these information notice elevator control gears 105 via signal wire (SW) 113 by power supply.Till elevator control gear 105 receives this notice (occurring till have a power failure), the main control unit 203 of elevator control gear 105 maintains to have a power failure prepares to process the power failure preparation operational mode of (A600), receive (A700) after this notice at elevator control gear 105, carry out storage battery operation and process (A800), operational mode is switched to storage battery operational mode.Process in the storage battery operational mode of (A800) in storage battery operation, in order to extend the period of service of storage battery 102, the target velocity of travelling is reduced to the speed below command speed, reduces and reach the acceleration/accel travelling before target velocity, and reduce the illumination of the illumination in car 108.
Whether checking has a power failure finishes, check whether the power failure end time being stored in memory storage 202 arrives, check via the signal wire (SW) 113 from electrical storage device 103 whether power supply has been switched to source power supply 101 (A900), while end when having a power failure, via signal wire (SW) 114, notifying device 111 in use car 108 has finished this information by power failure and has notified passenger, and turns back to common operation processing (A200).While also end when having a power failure, check the residual capacity (A1000) of storage battery 102 via the signal wire (SW) 113 from electrical storage device 103, in the time that residual capacity enough maintains storage battery operational mode, turn back to storage battery operation and process (A800).In the time that residual capacity is not enough to maintain storage battery operational mode, carry out end process (A1100).In end process (A1100), make car 108 be accommodated to nearest floor, open 108 of cars, and via signal wire (SW) 114, the notifying device 111 (telltale, loud speaker etc.) in use car 108 is about to stop this information by elevator operation and notifies passenger.
Prepare to process below (A600) is elaborated to having a power failure.
Check the motoring condition (A601) of car 108 according to the driving instruction information in memory storage 202 of being stored in by common operation processing (A200).Motoring condition also can be according to checking from the information that detects the position of car 108 and the sensor of speed.
In the situation that car 108 travels with command speed, stop instruction via signal wire (SW) 115 to 107 outputs of elevator drive control setup, make car 108 be accommodated to the next floor of nearest floor or nearest floor, after this return to the step (A601) that the motoring condition of car 108 is checked.The braking force of stop now instruction institute instruction is the braking force while slowing down under operational mode conventionally, can suppress thus the impact that brings because of velocity variations, can guarantee passenger's safety.Therefore,, in the time of nearest floor that the deceleration by common operational mode cannot make that car is accommodated to that original plan passes through, output makes car be accommodated to the stop instruction of next floor.In the time that the distance between the floor that current traveling-position and the plan of car 108 are stopped has several floors, stop instruction by output, can prepare the switching time of operational mode to having a power failure from operational mode in advance.In the above description, by till the Threshold having a power failure excess time of starting is T minute, if the value of this time T is arranged too smallly in order to extend the period of service of source power supply 101, if when the distance of once travelling of car 108 is longer, may during the travelling of car 108, have a power failure, so effective method is to prepare the switching time of operational mode to having a power failure from operational mode in advance.
If, in stopping and stop at the state on floor, being switched to operational mode to have a power failure from common operational mode, car 108 prepares operational mode (A603).Having a power failure in preparation operational mode (A603), car 108 is moved according to the speed lower than command speed, even if make car 108 carry out emergent stopping, also can not cause burden to passenger.In the time being switched to power failure preparation operational mode, indicating elevator driving control device 107 is using predefined low speed as the target velocity of travelling.The target velocity of travelling of indicated low speed is preferably identical with the target velocity of travelling of storage battery operation.Elevator drive control setup 107 continue to utilize source power supply 101 have a power failure prepare operation, until have a power failure occur.Now, via signal wire (SW) 114, use notifying device 111 (telltale, loud speaker etc.) output operational mode and the information for calling attention in car 108.
It should be noted that, in the explanation of the information for being provided to passenger by notifying device 111 (telltale, loud speaker etc.), omit a part of content, in the time that notifying device 111 provides information, provide operational mode, medium detailed information calls attention to, has a power failure.
In the above description, car 108 is prepared to the state of operational mode in the state of stopping and stopping on floor as operational mode being switched to have a power failure from common operational mode.Below illustrate at car 108 not in stopping and stop at the situation that under the state on floor, operational mode is switched to the preparation operational mode that has a power failure from common operational mode.Fig. 5 represents the curve that travels of lift car 108.Travel in curve at this, transverse axis is illustrated in X layer to the distance in the direction of Y layer, and the longitudinal axis represents the speed of lift car 108.The curve that the travels when curve 10 that travels is common operational mode, has the interval of carrying out constant-speed operation with command speed Vr.The curve 20 that travels is the curves that travel that have a power failure while preparing operational mode, has the interval of carrying out constant-speed operation with the speed Vs lower than command speed Vr.
As long as owing to travelling along the curve 40 that travels (speed successfully can be changed into the curve of speed Vs from 30 speed Vss (position that the distance of distance X layer is P) during the speed-raising of car 108), so, also can be arranged to when 30 speed during the speed-raising of car 108 be operational mode to be switched to have a power failure below the speed Vss of the low AV of specific rate Vs time to prepare operational mode.Can successfully change and refer at this time point of speed Vss velocity variations sharply can not occur, can not produce and overrun reaching this time point speed of speed Vs.In the present embodiment, be described as an example of the elevator that is provided with counterbalanced weight (CW) 110 example, owing to also there is speed Vss in the various elevators different with control method at the hydraulic pressure elevator that counterbalanced weight (CW) 110 is not set, so can obtain by computing or experiment.
Although also there is the interval of speed below speed Vss during the reduction of speed of car 108, but due in common operational mode, if do not stopped at Y layer, also do not stop at the assigned position of Y layer, so during reduction of speed, till car 108 stops, maintain common operational mode always, and as mentioned above,, before becoming at car 108 state of stopping and stopping on floor, do not carry out the switching of operational mode.
Below the charging of storage battery 102 is described.Owing to being that common operational mode or have a power failure is prepared when operational mode in operational mode, storage battery 102 carries out nature electric discharge, so need to charge to storage battery 102, makes storage battery 102 can keep rated capacity.In the time that storage battery 102 is charged, the regenerated electric power that uses the electric power of the device of solar generating on the roof of building that is arranged on elevator place or produced by the braking that elevator is stopped.Regenerated electric power is the electric power producing make electrical motor 106 move as electrical generator during in order to produce braking force.
It should be noted that, storage battery 102 is because of reasons such as property variations year in year out, and its natural discharge rate increases, and the charge volume that may produce storage battery 102 has been inputted the time point of power failure information lower than the situation of rated capacity from outside at communicator 201.The charge volume of storage battery 102 has been notified elevator control gear 105 via signal wire (SW) 113 from electrical storage device 103.Now, elevator control gear 105 is controlled electrical storage device 103, the time that makes the time point from having inputted power failure information or be enough in advance capacity to be charged to than the time opening that has a power failure rated capacity, use and from the electric power of source power supply 101, storage battery 102 is charged.Thus, be switched to the time point of storage battery operational mode in operational mode, the charge volume of storage battery 102 has reached rated capacity, so the elevator time of run can extend storage battery operational mode time.
As mentioned above, according to present embodiment, before the power failure of giving advance notice starts, use source power supply to have a power failure and prepare operation, the electric power that can suppress thus storage battery is consumed before power failure starts, and can elevator service be lasted till to the front and back that have a power failure in the situation that can not affecting safety.In addition, running mode switching before power failure starts, is reduced to the speed lower than command speed by elevator speed, can suppress thus the impact that the emergent stopping during travelling causes, thereby can guarantee passenger's safety.
