The specific embodiment
Followingly one embodiment of the invention are described with reference to accompanying drawing.
Fig. 1 is the related elevator device single-piece constructional drawing of one embodiment of the invention.At first, power to elevator device by circuit breaker 2 by source power supply 1.Wherein, the interrupting capacity of circuit breaker 2 is not and the corresponding value of the specified kW value of drive motor 3, but wishes that with the client who determines basic charge as per installed capacity in the electricity charge supply current value that adopts is worth accordingly.Be controlled at for the size with supply current below the restriction current value of circuit breaker 2, the output that will be used for detecting the current probe 4 of supply current sends to controller 5, and in restriction processing section 51 supply current is limited.Supply current charges so that it becomes direct voltage source to smooth condenser 7 after flowing into rectifier 6 and rectification therein.The both end voltage of this cond is detected and is input in the controller 5 by piezoelectric detector 8.In addition, the voltage and current of electrical storage device 9 is detected by piezoelectric detector 10 and current probe 11 respectively, and is sent to controller 5.Control so that it moves by 3 pairs of DC-DC converting means 12 of control signal wire, thereby the restriction of carrying out smooth condenser voltage and supply current is controlled.Then, the voltage source of smooth condenser 7 as power supply, is made inverter 14 actions, thereby drive motor 3 is driven.At this moment, the outgoing current of inverter is detected by current probe 15, and the rotative speed of electrical motor is detected by impulse deviser 16, carries out computing by electric current and speed control processing section 52 in the controller 5, via the conducting and the disconnection of the group of switching elements in control signal wire 17 control inverters 14.Be wound with hoist cable 19 on the drive motor 3 bonded assembly rope sheaves 18, via this hoist cable 19 suspention weight-saving balance weight 20 and elevator car frame 21.Be provided with load sensor 22 in this elevator car frame 21, basic data collection and balance weight weight that patronage signal in the car sends in the controller 5 change in the query processing part 55, and use in optimal balance point calculating described later and balance weight change query processing.
This weight-saving balance weight 20 can realize energy-saving run effectively (this kind condition of service occurrence rate in apartment etc. is very high) under the few condition of service of patronage, and its weight preferably sets at about 20~35% of specified passenger weight.The patronage of this lightweight initial value during also can be according to the rules detects data computation and draws, and perhaps rule of thumb is worth and sets value about 25% for.
The weight change of balance weight 20 is handled, after obtaining the approval of client to the inquiry of balance weight change query processing part 55, by the maintenance company execution of elevator.Promptly, via internet 26, the weight data of the optimum balance counterweight that the basic data that will collect according to controller 5 is calculated and calculate that the slave controllers such as data 5 of energy-saving effect directly send to client terminal 25, perhaps the terminal 27 via elevator reparing company sends to client terminal 25.After sending the letter in reply that expresses one's approval the client, accept this letter in reply, and the weight of balance weight is changed to suitable weight by the maintainer by the final terminal 27 of controller 5 or elevator reparing company.
For example, after initial value being set at 25% equilibrium point, if the passenger is more than what estimate, after obtaining requirement of client, the value that can average out between the burden in the time of also equilibrium point can being changed to energy-conservation and heavy load for example makes equilibrium point into 35% equilibrium point.
But, in system, when heavy load, because its unbalance factor is big, so inverter will bear excessive burden with lightweight balance weight 20.At this, in order to alleviate Heavy Duty, handle by operation restriction processing section 53, so that suppress heating, thereby prevent that deterioration from appearring in on-off element because of being heated.Specifically, the processing of operation restriction processing section 53 is, from suppressing the heat-producing viewpoint of switch, rather than from reducing the angle of constant current, control the switching frequency of inverter lower than the switching frequencies of light hours, perhaps the action of inverter is controlled, made it become bi-phase modulated etc. from three-phase modulations.In addition, this moment by inform carry out energy-saving run inform processing section 54, at adverse factors such as noise that is taken place and torque fluctuation increases, inform elevator user and the passenger who waits at elevator lobby, to allow everybody go and find out what's going on and to obtain everybody understanding.Promptly, the explanation that use is arranged in the lift car 23 and loud speaker 24 grades of telltale in the elevator lobby and broadcasting usefulness are easily understood, inform everybody because implementing energy-saving run, so noise and torque fluctuation can increase to some extent, but this energy-saving run helps information such as energy-conservation.For example, amount of energy saving is converted into the amount of money or former oil mass shows, then than the understanding that is easier to obtain the passenger.And,, will be elaborated successively according to treatment scheme (treatment scheme data) in the aftermentioned part with reference to the later accompanying drawing of Fig. 3 about the action of the various piece in the controller 5.
Fig. 2 is the equilibrium point instruction diagram of one embodiment of the invention.The equilibrium point of Fig. 2 (A) expression balance weight is set at 50% o'clock situation, and the equilibrium point of Fig. 2 (B) expression balance weight is set at 25% o'clock situation, and Fig. 2 (C) represents that then the equilibrium point of balance weight is set at 35% o'clock situation.
Shown in Fig. 2 (A), when the equilibrium point of balance weight is set at 50%, upwards moving among the UP, when passenger weight is between 0~50%, current value is negative value, and promptly in the operation of regenerating, and passenger weight is between 50~100% the time, then current value be on the occasion of, promptly carrying out electronic (motoring) operation.On the other hand, in downward operation DN, when passenger weight is between 0~50%, current value be on the occasion of, promptly carrying out electric operation, and passenger weight is between 50~100% the time, then current value is negative value, promptly in the operation of regenerating.
At this, suppose as the passenger weight 201 in service object's building mostly about 25%, then when upwards moving UP, need bigger regenerative current, and when operation DN downwards, need bigger electronic electric current.
In the present embodiment, in order to alleviate the weight of balance weight, the initial value of balance weight equilibrium point is set in 25% of passenger weight.At this moment, can know,, when up UP and descending DN, all only need very little electronic electric current or very little regenerative current at main passenger weight 201 about 25% from Fig. 2 (b).
But, from figure, can also know, if near just in case passenger weight when having reached 100%, then need very big electronic electric current or very big regenerative current.
At this moment, at first electric current is provided with the restriction of limits value ± Imax, the electric current that exceeds part is then supplied with by electrical storage device 9.Current Ib is the discharge current of electrical storage device 9, and electric current-Ib represents charging current.
Then, after the agreement that obtains user and client, can the operation of elevator be limited.Inform that the passenger owing to implement energy-saving run, need obtain passenger's assistance, wish that the passenger is conscious to avoid once taking too much passenger.For this reason, preferably inform the information that the generation that comprises average patronage, date, service direction, on-board and off-board floor etc. and the reckoning in distribution situation, operation restricted information, power savings, the electricity charge or the traditional elevator systems consume the comparative data of electric power, the electricity charge and this elevator device to passenger and client.
Below the initial value of balance weight promptly is equivalent to 25% passenger weight the too light situation of equilibrium point describe.Consume the comparative data of electric power, the electricity charge and this elevator device etc. according to the reckoning in above-mentioned average patronage, operation restricted information, power savings, the electricity charge or the traditional elevator systems, can know more suitable balance weight weight.According to these information, will comprise the information notification client in the weight whether its inquiry can change balance weight 20 is set in.Then, if after receiving the letter in reply that the client agrees, by the maintainer of maintenance company with the weight of balance weight 20 for example change setting be 35% equilibrium point.
The state of electric current is after changing set in Fig. 2 (c) expression.At being the load 202 at center, can move with very little electronic electric current or regenerative current with 35% of specified passenger weight.At this moment, described electric current restriction of also preferred execution graph 2 (b) and operation restriction.
Fig. 3 is the processing flow chart of the supply current restriction processing section 51 of Fig. 1.This control operation is organized on the time meter interruption operation that starts with short time interval in the control convenience of micro computer etc. by being connected on down.After this job initiation, at first in treatment step 511, read in the data such as patronage, service direction, inverter outgoing current, smooth condenser voltage, electrical storage device voltage and electrical storage device electric current in supply current, the lift car.Then, in treatment step 512, calculate or detect the maxim of this operating supply current, and judge in treatment step 513 whether maximum current has surpassed the disconnection restriction electric current of circuit breaker 2 according to patronage and service direction.If surpass, then in treatment step 514, make 12 actions of DC-DC converting means, shown in the current Ib of Fig. 2 (b), from electrical storage device 9 power supplies the voltage of smooth condenser 7 is risen, thereby will be suppressed at below the limits value of circuit breaker 2 from the inflow current of power supply.This pattern is using lightweight balance weight system and patronage to occur during operation under near the fully loaded heavy load conditions, but in apartment etc., can occur this kind use pattern hardly, carry out this viewpoint of number of times that the degree of depth discharges and recharges from electrical storage device 9, be rarely found pattern.If when judging maximum current than limits value little (denying), then can not make electrical storage device 9 actions, and only rely on little inflow current to drive elevator from mains side, the viewpoint from the restriction electric current can reduce basic charge as per installed capacity.In addition, many and use in the low equilibrium point system of lightweight balance weight in the chance of light(-duty) service, almost all under this operational mode, move.Therefore, when being organized into the common system that at equilibrium point is 45~50%, the degree of depth that discharges and recharges of electrical storage device 9 and number of times and electrical storage device compare, and all very little, so be very beneficial for improving the life-span of electrical storage device.And, judge in treatment step 515 whether the voltage of electrical storage device descends very lowly.If answer is yes, then in treatment step 516, make 12 actions of DC-DC converting means, with the deep charge number of times that is controlled in the Min. electrical storage device 9 is charged.On the other hand, when if the voltage of electrical storage device also is not very low (the answer is in the negative), then consider and do not carry out the charging process of electrical storage device, handle 517 and finish the processing of the restriction processing section 51 of supply current through returning from the angle that improves the electrical storage device life-span.The restriction of this supply current is handled except the effect with common reduction basic charge as per installed capacity, owing in most cases move with the light load condition, the charging times of electrical storage device has obtained significantly reducing, so, also have and to prolong this new effect of electrical storage device life-span as the peculiar effect of low equilibrium point system.
Fig. 4 is the electric current of Fig. 1 and the processing flow chart of speed control processing section 52.This processing also is the operation that starts at regular intervals.After the startup, in treatment step 521, read in inverter outgoing current and the output pulse that is installed in the impulse deviser 16 on the electrical motor, in treatment step 522, export the actual speed of pulse calculating motor and the operating range of lift car then according to this, if electrical motor is a magnetic motor, then calculate its position of magnetic pole.In treatment step 523, obtain the speed command of in other operations, calculating and the deviation between the actual speed then to calculate torque current command.In treatment step 524, obtain voltage instruction (modulating wave) then according to the deviation between this current-order and the detected inverter current.When this voltage instruction is made of on-off element at inverter 14, then compare with carrier wave in treatment step 526, with the production burst amplitude modulation command, this instruction outputs to on-off element in the inverter as conducting and open command via control signal wire 17.This electric current and speed control processing section 52 are essential parts of motor control, and this processing itself is common processing, but the operation restriction during with heavy load described later such as speed command that this place uses and carrier wave has very dark relation, so it is described.
The processing flow chart of the operation restriction processing section 53 when Fig. 5 is the heavy load of Fig. 1.This processing also is the operation that starts at regular intervals.After the startup, in step 531, read in data such as patronage, service direction and position.In treatment step 532, calculate amount of unbalance between balance weight side and the lift car side according to these information, in treatment step 533, judge the size of amount of unbalance, if amount of unbalance little (the answer is in the negative), the Heavy Duty sign is resetted, owing to do not move restriction and can not cause harmful effect yet to inverter, so end process is carried out common operation afterwards via treatment step 537.If during amount of unbalance big (answer is yes); then in treatment step 534, represent this amount of unbalance with sign; in the operation restriction execution of treatment step 536 is handled, physical constraints is carried out in operation,, handle 537 back end process via returning afterwards with the protection inverter.In addition, different with office block etc., in apartment etc., elevator moves under the few state of passenger substantially.So, carry out seldom, but read in the information of expression heavy loads such as patronage and current value at this corresponding to the situation of this processing of heavy load, limit operation, can bring into play the effect of avoiding inverter etc. to come to harm.
Fig. 6 be with Fig. 5 in Heavy Duty the time operation limit the concrete processing flow chart of carrying out processing section 536 accordingly.This expression be to be included in restriction to carry out embodiment in the inter-process of processing section 53, but also it can be arranged to high frequency initiating task as processing independently.Operation restriction is carried out after processing section 536 starts, and in treatment step 5361, as the indirect processing of avoiding the Heavy Duty operation to occur in advance, carries out that the requirement passenger modestly declines and the processing avoiding crowding.At first, carrying out the requirement of indirect handles, for example require the passenger to cooperate and do not clamp-on elevator by telltale in elevator lobby and the lift car and loud speaker etc., make fully loaded alarm buzzer phone send tweeting sound then, and, prolong the shut of elevator door etc. in order to give the passenger time to consider.Then, judge in treatment step 5362 whether the Heavy Duty state improves.If be improved, then be judged as and there is no need to proceed restriction, and handle 5368 back end process, and provide service with common operation via returning.If the state of Heavy Duty does not improve, then directly limit.In treatment step 5363, judge whether to be in the state that need carry out quiet operation in night or morning etc.If when not needing to carry out peace and quiet operations (the answer is in the negative), in treatment step 5367,, reduce the conducting of on-off element in the inverter and the processing of open circuited number of times as the method for operation restriction.One of reason that on-off element is damaged is heating, heating is by the stable component of electrical current with along with conducting and the two sum of transient part that disconnection produces by the active region time are caused, at this, by reducing the Heavy Duty that transient part reduces inverter.That is, the switching frequency when realizing working by pulse width modulation by reducing carrier frequency is prepared for carrying out restriction.Because conducting and open circuited number of times reduce, cal val reduces, but conducting and open circuited number of times have been reduced to the degree that people's ear can be heard, so the harsh noise that electrical motor produces increases.However, if be in the peace and quiet operation is not had under the state of specific (special) requirements, owing to can consider from service angle for the passenger provides essentially identical time of run performance, above-mentioned method for limiting ratio is easier to make the passenger to satisfy.Carry out the peace and quiet operation if desired, then in treatment step 5364, judge the length of range ability.If range ability is short, then maximum speed is not reduced to and causes the degree of too big problem can for the arrival time.That is, obtain maximum current according to loading condiction, corresponding to and current limit value between relation and reduce maximum speed instruction, prepare for carrying out restriction.In addition,, make three-phase modulations into bi-phase modulated when then in treatment step 5366, carrying out pulse width modulation, the switch motion that makes sine wave outputization is limited, to suppress the moment heating if judge that in treatment step 5364 range ability is long.Because torque fluctuation increases, the vibration of lift car increases slightly, but above-mentioned method for limiting has the effect that alleviates the inverter Heavy Duty.More than in treatment step 5365~treatment step 5367 method to various reduction Heavy Duty be described, said method can be selected wherein a kind of separately, if but burden is very big, then a plurality of methods in the above-mentioned method for limiting can be implemented simultaneously.
Fig. 7 is the concrete processing flow chart of the executory information notification of energy-saving run processing section 54.This processing also is the operation that starts at regular intervals.After the startup, in step 541, read in data such as patronage, service direction, speed, operating range, power line voltage, supply current, contravarianter voltage, electric current.Calculating and store this then moves needed electric energy, the electricity charge, is converted into the oil amount of crude oil, does not adopt electric energy, the electricity charge in the conventional lift of lightweight balance weight system, is converted into the reckoning amount of the oil amount of crude oil.Then, in treatment step 543, inform the information relevant with the restriction operation every specific time with energy-conservation result by telltale or loud speaker etc.Because the reckoning amount by telltale in elevator lobby and the lift car or loud speaker etc. have in time been informed consumed power and compared and save the electricity charge and be counted as the oil amount of crude oil with traditional approach can allow elevator passenger be directly acquainted with the effect of energy-conserving elevator effect so have.And, in treatment step 544, by network the energy-conservation related data that is accumulated is sent to the information terminal that building handler and elevator passenger are the occupant etc. in apartment at regular intervals, also can play making it to energy-conservation satisfied effect.And, in the above description, this treatment step 544 is to start short time of being separated by, but because this step informs is cumulative data, so also can set longlyer by the pitch time that the loop time meter will handle is set, perhaps with it as independently working, and with the number of times that starts be provided with a little less.
Fig. 8 is the concrete processing flow chart of basic data collection and balance weight weight change query processing part 55.This processing also is the operation that starts at regular intervals.After the startup, in treatment step 551, collect and store patronage, service direction, take advantage of, arrive elevator services contamination such as layer, time of origin, supply current, inverter outgoing current into layer.Then, in treatment step 552, with the weight of balance weight as imposing a condition, with patronage and frequency as parameter, according to collecting and canned data is estimated the consumed power and the electricity charge etc.This estimated data sends to customer information terminal via network in treatment step 553, to inquire the balance weight change query processing that whether can be altered to lightweight balance weight system.At this moment, except energy-conservation estimation situation, can also be at the unfavorable factor that adopts lightweight balance weight system, the aging of Heavy Duty caused on-off element of when operation and electrical storage device and expense expenditure that the clearing house needs etc. promptly taking place also make consideration, calculates energy-saving effect on this basis and inform.In treatment step 554, judged whether to obtain the agreement of client to the balance weight change.If obtained client's agreement, then wish to implement low balance and reveal, and provide job requirements to maintenance company by network as the client.If do not obtain answering, then as awaiting acknowledgement and end process.The urgency level of treatment step 554~555 is low, therefore can independently be arranged to the operation of the low number of starts.In addition, client's answer also can directly not send to the terminal 27 of elevator reparing company by the controller 5 of each elevator.In a word, the transportation data that the service condition of each building, each elevator and the elevator of each time period is relevant is carried out Collection and analysis, and energy-saving effect and Heavy Duty situation taken in, carry out the change of equilibrium point after the agreement that obtains the client, this mode also has effect aspect the understanding that obtains the client.
