This elevator possesses electrical motor 11, pulley 12, rope 13, car 14, counterweight (bob-weight) 15.
The driving power that electrical motor 11 is stipulated and spinning movement.Pulley 12 is installed on the S. A. of electrical motor 11.Rope 13 is wound on the pulley 12, and car 14 and counterweight 15 are installed on its two ends.
In addition, this elevator possesses source power supply 21, rectifier 22, smooth condenser 23, changer 24 and converter current detecting device 25, as the drive system of car 14.
In addition, above-mentioned source power supply 21 is three phase mains.The alternating-current voltage/AC voltage of this three phase mains is absorbed the fluctuation part by smooth condenser 23, thereby is smoothly turned to direct current by rectifier 22 biphase rectifications.The direct current of this smoothing is provided for changer 24, is transformed to the alternating-current voltage/AC voltage of assigned frequency, is re-used as driving power and supplies in the electrical motor 11.
Come rotary driving motor 11 by such power supply, pulley 12 rotates thereupon.And, make car 14 and counterweight 15 in lift path, carry out lifting action with bucket type via the rope 13 that is wound on the pulley 12.
In addition, this elevator possesses speed instruction device 26, speed detector 27, speed control unit 28, load detection switching device 29, load signal arithmetical device 30, torque instruction judgment means 31 and converter current control setup 32, as operating control system.
The never graphic control board for elevator of speed instruction device 26 is accepted the running instruction of electrical motor 11, output speed command value.Speed detector 27 detects the current speed of electrical motor 11.Speed control unit 28 is obtained the deviation of speed value and speed detected value, and the such torque instruction of this deviation is eliminated in output.
Load detection switching device 29 is the switches that are used for detecting car 14, for example is made of a plurality of switches that carry out turn-on action according to load value selectively.Load signal arithmetical device 30 is according to the load signal from 29 outputs of load detection switching device, computing compensated torque value.
Particularly, suppose that above-mentioned load detection switching device 29 is made of 3 switch a, b, c.Conducting when switch a weighs than the load capacity of stipulating (with the weight of counterweight 15 balances) at the load value of car 14.Conducting when switch b is the load capacity of afore mentioned rules at the load value of car 14.Switch c conducting when the load value of car 14 is lighter than the load capacity of afore mentioned rules.Load signal arithmetical device 30 as shown in Figure 2, corresponding to the Continuity signal separately of these switches a, b, c, output for example be the compensated torque value of " 10 ", " 0 ", "+10 ".
Torque instruction judgment means 31 is judged final torque instruction value whether in allowed band, and this final torque instruction value will obtain from the torque instruction value of speed control unit 28 outputs and compensated torque value addition from 30 outputs of load signal arithmetical device.If consequently torque instruction value is outside allowed band, then apply killer so that it is included in the allowed band.
Converter current control setup 32 bases are by converter current detecting device 25 detected current values and the torque instruction value of exporting from torque instruction judgment means 31, and the cooperation torque instruction value controls flow to the electric current in the electrical motor 11.
In addition, in the elevator of present embodiment, except structure as described above,, also possess electrical storage device 41, piezoelectric detector 42, charge-discharge controller 42a, charge-discharge circuit 43 as hybrid drive system.
Say that at length electrical storage device 41 is arranged on the input terminal side of changer 24.In the input terminal side of this changer 24, be provided with piezoelectric detector 42 in parallel with smooth condenser 23.Detect the terminal voltage of smooth condenser 23 by this piezoelectric detector 42.
When car 14 was the power running and operating, the voltage of smooth condenser 23 kept the magnitude of voltage of regulation.Here, if car 14 switches to regeneration operating, then regenerated energy is got back to the input terminal side from changer 24, so the terminal voltage of smooth condenser 23 is than the magnitude of voltage rising of afore mentioned rules.By detected the variation of this magnitude of voltage by piezoelectric detector 42, it is power running and operating or regeneration operating that charge-discharge controller 42a judges.
In addition, be provided with charge-discharge circuit 43 and electrical storage device 41 in parallel with smooth condenser 23.Charge-discharge circuit 43 is the circuit that discharge and recharge that are used for switching to electrical storage device 30.This charge-discharge circuit 43 has charging on-off element 44, discharge on-off element 45, direct current reactor 46 etc.Charging is between dc bus with the power supply line that on-off element 44 and discharge are connected to changer 24 in parallel with on-off element 45.Direct current reactor 46 is connected on the shared connecting portion of these on-off elements 44,45, makes the dc power smoothing.
Here, explanation possesses the action of charge and discharge of regenerated energy of the hybrid drive-type elevator of electrical storage device 41 simply.
(a) charging of regenerated energy action
As mentioned above, when the regeneration operating of car 14, make regenerated energy get back to the input terminal side from changer 24.Thereby regenerated energy is stored in the smooth condenser 23, rises gradually as the voltage between the dc bus of the power supply line of changer 24.The voltage of this moment rises and is detected by piezoelectric detector 42, and offers charge-discharge controller 42a.
In charge-discharge controller 42a, if the voltage between above-mentioned dc bus becomes more than a reference value that sets in advance, then with on-off element 44 conductings of the charging in the charge-discharge circuit 43.Thus, regenerated energy is charged in the electrical storage device 41.
(b) discharging action of regenerated energy
When the power running and operating of car 14, will supply in the changer 24 by the direct current after smooth condenser 23 smoothings.Thereby, descend when voltage ratio stops between the dc bus of the power supply line of changer 24.The voltage of this moment descends and is detected by piezoelectric detector 42, and offers charge-discharge controller 42a.
In charge-discharge controller 42a, lower if the voltage between above-mentioned dc bus drops to than predefined a reference value, then with on-off element 45 conductings of the discharge in the charge-discharge circuit 431.Thus, the regenerated energy that is stored in the electrical storage device 30 is discharged to the power supply line.
In the hybrid drive-type elevator that constitutes like this, if for example wait and become the state that normally to supply with the power of source power supply 21 because of having a power failure, then the voltage of smooth condenser 23 descends, and this state quilt detects with the piezoelectric detector 42 that smooth condenser 23 is arranged in parallel.Thus, the discharging action by above-mentioned charge-discharge circuit 43 releases energy from electrical storage device 41, supplies in the changer 24.
Under such situation owing to have only electrical storage device 41 as propulsion source, so if the off-capacity of electrical storage device 41, then might impassabitity changer 24 driving motors 11, in advancing car 14 in the Halfway Stopping of each layer.
So, in the 1st embodiment, make when the energy shortage car 14 to the structure that the most approaching layer stops safely as being used for, possess current sensing means 50, voltage check device 51, energy capacity monitor unit 52, direct of travel reversing gear 53.
Current sensing means 50 is by being connected the current value of the current probe 48 detection electrical storage devices 41 on the electrical storage device 41.Voltage check device 51 detects the magnitude of voltage of electrical storage device 41.52 pairs of energy capacity monitor units multiply by the time composition by current sensing means 50 detected current values with by voltage check device 51 detected magnitudes of voltage, calculate the current energy capacity of electrical storage device 41.
In addition, direct of travel reversing gear 53 will make the instruction of the direct of travel counter-rotating of car 14 export to speed instruction device 26 according to the energy capacity that is calculated by energy capacity monitor unit 52.
According to such structure, calculate the current energy capacity of electrical storage device 41 by energy capacity monitor unit 52.In the case, if the current value of establishing by current sensing means 50 detected electrical storage devices 41 is I, the magnitude of voltage of establishing by voltage check device 51 detected electrical storage devices 41 is V, and then the energy capacity Q of electrical storage device 41 represents with following such formula (1).In addition, t is the time.
Q＝I×V×t[W·h] ……(1)
Here, if wait the energy that continues to consume electrical storage device 41 because of having a power failure, the value of above-mentioned Q drops to and is lower than specified volume Qt, and then energy capacity monitor unit 52 is judged the required off-capacity of advancing of cars 14, to direct of travel reversing gear 53 output capacity shortage signal.In addition, afore mentioned rules capacity Qt is not zero, and is set at about 20% of whole volume for example according to the characteristic of electrical storage device 41 etc.
Direct of travel reversing gear 53 if car 14 is in the power running and operating, then sends instruction so that its direct of travel changes to direction of regeneration to speed instruction device 26 if receive the off-capacity signal from energy capacity monitor unit 52.
In the case, because the energy of electrical storage device 41 is in consumption state, be in the power running and operating so can judge car 14.If be in the regeneration operating, then owing to not consuming the energy of electrical storage device 41, so can off-capacity.Thereby, in speed instruction device 26,, then car 14 is reversed to direction of regeneration from the power service direction if receive instruction from direct of travel reversing gear 53, run to the most approaching layer and stop.
Fig. 3 is the figure that is used for illustrating the operative condition of car 14.From last beginning represent successively from speed instruction device 26 output speed command, when having a power failure car 14 the running figure, from the off-capacity signal of energy capacity monitor unit 52 outputs.In addition, in the running figure of the car 14 when having a power failure, downward diagrammatic representation is advanced to reversing sense.
Now, suppose from 1F power failure to have taken place to 3F advances with the speed of stipulating at car 14.In this case, utilize the regenerated energy be stored in the electrical storage device 41, Yi Bian car 14 underspeed, Yi Bian advance to a certain degree.In addition, the running of this moment is owing to the regenerated energy with electrical storage device 41 is a power, so be the power running and operating.
Here,, the energy capacity Q of electrical storage device 41 is lower than afore mentioned rules capacity Qt, then from energy capacity monitor unit 52 output capacity shortage signal if dropping to.Thus, the direct of travel of car 14 is switched to direction of regeneration, stop at hithermost layer.For example,, then make quarter car 14 at this moment, on the floor ground of immediate 2F, stop to the reversing sense running if between 2F and 3F, become off-capacity.
Like this, in hybrid drive-type elevator, for example electrical storage device 41 is become under the situation of energy shortage because of take place to have a power failure waiting, to switch to reversing sense be direction of regeneration and stop at the most approaching layer by the direct of travel with car 14, can prevent that car 14 from the interlayer Halfway Stopping, can guarantee passenger's safety.
In addition, in above-mentioned the 1st embodiment, when detecting the energy shortage of electrical storage device 41, with car 14 when being in the power running and operating and directly travel direction counter-rotating.But,, be preferably after having confirmed to be the power running and operating car 14 directions reversed in order to carry out more accurate running control.This can by for example by charge-discharge controller 42a according to the both end voltage value (voltage between dc bus) of smooth condenser 23 judge current car 14 operative condition (power running and operating/regeneration operating), this operative condition signal offered direct of travel reversing gear 53 realize.
(the 2nd embodiment)
Then, the 2nd embodiment of the present invention is described.
In above-mentioned the 1st embodiment, when detecting the off-capacity of electrical storage device 41,, go up the counter-rotating of car 14 directions, but in the 2nd embodiment, it is characterized in that, determine whether the travel direction counter-rotating according to the position of the car 14 of this moment.
Fig. 4 is the figure of expression about the structure of the control setup of the hybrid drive-type elevator of the 2nd embodiment of the present invention.In addition, give identical label for the part identical, and omit its detailed explanation with the structure of Fig. 1 in above-mentioned the 1st embodiment.With the difference of the structure of Fig. 1 be to have appended car position detector 54.
In Fig. 4, car position detector 54 detects the position of the car 14 in the lift path, and this position detection signal is exported to direct of travel reversing gear 53.Direct of travel reversing gear 53 is according to the car position that obtains from car position detector 54, judge whether more to approach the most approaching layer than turning round, speed instruction device 26 is exported in direction counter-rotating instruction according to this judged result to the power service direction to the direction of regeneration running.
Fig. 5 is the diagram of circuit of processing action of the control setup of the hybrid drive-type elevator of expression in this embodiment, the action of expression when energy capacity monitor unit 52 has been exported the off-capacity signal.
That is, suppose for example to have exported the off-capacity signal from energy capacity monitor unit 52 now because of taking place to have a power failure to wait.
Direct of travel reversing gear 53 is at first obtained current car position (step S12) from car position detector 54 by receiving off-capacity signal (step S11).And direct of travel reversing gear 53 calculates car 14 original states arrive the most approaching layer from current car position when the power service direction advances distance (being made as L1) (step S13).In addition, the location information of supposing each layer has been provided for direct of travel reversing gear 53.
Then, direct of travel reversing gear 53 calculates car 14 arrives the most approaching layer from current car position when direction of regeneration counter-rotating and running distance (being made as L2) (step S14).
Here, direct of travel reversing gear 53 will be in above-mentioned steps S13 distance L 1 that calculates and the distance L 2 that calculates at above-mentioned steps S14 relatively.In its result is under the situation of L1＞L2, i.e. under the situation of direction of regeneration running the most approaching more close layer (being among the step S15), direct of travel reversing gear 53 makes car 14 advance to reversing sense in order to utilize regeneration rotation, to speed instruction device 26 outbound courses counter-rotating instructions (step S16).
On the other hand, under the situation of L1≤L2, promptly under the situation of power service direction running the most approaching more close layer or be under the situation of distance of same degree (step S15 is), direct of travel reversing gear 53 not sender makes car 14 original states to power service direction advance (step S17) to counter-rotating instruction.
According to this structure, for example as shown in Figure 3, when car 14 was come near the floor ground of 3F, 2F was not got back in the direction of passage counter-rotating, and was to use the residual volume of electrical storage device 41 to advance to 3F and stops.
Like this, in the time of near car 14 is come certain layer, do not make car 14 directions counter-rotatings, but original state advances and stop at the most approaching layer to the power service direction, thus, can rescue can not bringing under the caused uneasy situation about feeling of direction counter-rotating to the passenger.
