Description
Technical field
The invention belongs to elevator method of inspection and detecting device, especially belong to elevator energy consumption method for comprehensive detection and detector.
Background technology
Elevator is one of consumer of modern architecture maximum, and the power consumption of elevator is only second to the idle call electric weight, far above the power consumption of systems such as illumination, water supply.Traction elevator is to use the most general a kind of elevator in the vertical transportation transportation means, the reality that drags of elevator is exactly that traction motor is carried out rotating and speed control, but since the counterbalancing of elevator the weight of car and fractional load, therefore concerning motor, its load characteristic is slightly different with other weight-lifting equipment, it may not need acting when up, and may need acting when descending.Owing to always do during the elevator operation; following crank motion; and the load of car changes through regular meeting; therefore motor is normally worked under electronic and two kinds of alternating states of generating; at present the situation of energy-conserving elevator is: when elevator zero load or underloading up and heavily loaded or fully loaded when descending; machine operation is under the dynamic brake state; what motor was done is negative work; mechanical energy is converted into electric energy; difference according to the elevator driving style; these electric energy can consume on motor; on the braking resistor; perhaps feed back to (the part elevator does not also utilize this part energy) on the electrical network; elevator zero load or underloading are descending and heavily loaded or fully loaded when up; machine operation is under motoring condition, and this moment, motor absorbed energy from electrical network, and electric energy is converted into mechanical energy.The energy consumption complexity of elevator as can be known in sum is not that up in our the common notion must be power consumption, descending must the generating.The relation of the mode of operation of elevator load and service direction and motor sees the following form.
(annotate: m is meant load-carrying, and Q is meant the lift car deadweight, and G is meant the counterweight of elevator)
The energy consumption of lift product self mainly comprises: the energy consumption of traction system, comprise the loss of the energy consumption of energy consumption, balancing device and the trailing cable of towing machine loss, car and counterweight, the loss of steel rope etc., drive system, the energy consumption that control shows: all control circuits and the display circuit (except the control system of door mechanism system, it being included into the energy consumption of door mechanism system) that comprise machine room, stop and car; The energy consumption of door mechanism system comprises the control system of door mechanism system and the energy consumption of drive motor; Illumination in the lift car, the energy consumption of ventilation system miscellaneous equipments such as (fan or air-conditionings).In running process of elevator, the ratio difference that the each several part energy consumption is shared.In general, the energy consumption of elevator drive and traction system accounts for about 75% of elevator total energy consumption; The energy consumption of elevator door-motor system accounts for about 12% of elevator total energy consumption; The energy consumption of equipment such as the control of elevator and demonstration, illumination, ventilation system accounts for about 13% of elevator total energy consumption.
The testing of China's elevator energy efficiency is at the early-stage; the main manual measurement that adopts; owing to adopt manual measurement elevator energy consumption index precision low; data volume is big; inefficiency; studying at present and making the energy consumption detector; through having looked into Chinese patent ZL00820141789.2 " elevator energy efficiency detector "; but this detector can only detect the dynamic energy consumption that elevator carries surely; and the dynamic energy consumption of elevator dynamic load; and the standby energy consumption of elevator is meant that elevator rests on certain layer; illumination in the elevator and ventilation system etc. are still in open mode; elevator dormancy energy consumption is meant that elevator is after static a period of time; for the illumination of power saving elevator and ventilation system etc. are closed; but control part is still in operation, and the door function of elevator consumes, and these three states can't detect with this detector; and shut down detection, use with reality to also have certain difference.
Summary of the invention
The object of the invention is to overcome present elevator energy consumption and detects the shortcoming that exists, and a kind of energy consumption under can the various operating modes of objective record elevator is provided, science, comprehensively, the elevator energy consumption method for comprehensive detection and the detector that objectively the energy consumption of elevator are detected.
The technical solution adopted in the present invention is a kind of elevator energy consumption method for comprehensive detection, its main points are that standby energy consumption with the unit time is as elevator energy consumption based measurement energy consumption, the energy consumption of elevator is carried out the category measurement statistics, with the state before each state variation is frame of reference, the energy consumption that at every turn changes is carried out statistic of classification, promptly with the aggregate-value E1 of the energy consumption measurement before changing as frame of reference, the aggregate-value E2 that changes the back energy consumption measurement is carried out subtraction with the aggregate-value E1 that changes preceding energy consumption measurement, the result is deducted the standby energy consumption of unit time and the product of this variation Δ perdurability t again, just draw the energy consumption of this kind state variation, described standby energy consumption is meant that elevator is static, but the illumination of elevator and the ventilation system elevator energy consumption when starting.
By long-term test and observation, we find that elevator energy consumption is comprehensively to be formed by several fixing consumers in special time period, its each variation all has tangible consumer to increase or reduces, standby energy consumption is a kind of basic status of elevator, it is the intermediateness of various state variation, other elevator state all is to increase or reduce certain consumer on this basis, do the basis with it, can reject the energy consumption of other consumer out respectively, the energy consumption of some consumer belongs to metastable energy consumption, after limited number of time is measured, can no longer measure, with the simplified measurement process.As elevator when moving up and down, its obvious characteristic is that traction motor is in work, the gated motor of elevator door-motor system is just changeing and is just beginning the work of opening the door after traction motor quits work, after the end back gated motor that opens the door quits work, the passenger advances, go out the car back gated motor counter-rotating that finishes and begin the work of closing the door, the end of closing the door, after gated motor quits work, traction motor is started working and elevator is moved up and down or is stopped ladder, therefore can be by the method for pure mathematics, accumulative total energy consumption before the state variation is carried out subtraction as the frame of reference of the accumulative total energy consumption of state variation end, promptly subtract each other with energy consumption aggregate-value E2 after changing and variation energy consumption aggregate-value E1 just, the result is deducted the standby energy consumption e and the product that changes Δ t perdurability of unit time, just draw the energy consumption of the consumer that this kind state variation increases or reduce, we rationally classify the various energy consumptions of elevator according to the moving law of elevator, the energy consumption of each variable is carried out statistic of classification, thereby for the actual consumption of elevator make objective, scientific measurement provides the foundation of system science for reducing elevator energy consumption.
The classification of the elevator energy consumption of this method is that elevator is divided into two kinds of delivery energy consumption and characteristic energy consumptions.The delivery energy consumption is meant that elevator uses and finishes energy consumption manned or that the loading operation is consumed down, and the characteristic energy consumption is meant the additional energy consumption that elevator produces in order to carry out manned or loading.The delivery energy consumption is divided also can be subdivided into the up energy consumption of delivery, deliver descending energy consumption; the characteristic energy consumption is divided into no-load power consumption, door function consumption, shuts down energy consumption; with the delivery energy consumption of statistics distance and the weight delivery energy consumption that obtains unit weight and distance, the no-load power consumption of statistics is obtained the no-load power consumption of unit distance divided by the distance of operation divided by delivery.
At present change into electric energy and be connected to the grid for elevator the has been in operation negative work done of the part elevator that cuts down the consumption of energy; after being longer than setting-up time (being generally 5 minutes), the elevator floor time closes simultaneously the illumination and the ventilation system of elevator; only stay the most basic control part of elevator in work, to reduce energy consumption.The elevator that native system has taken into full account these advanced power savings improves, with it also as the detection target.

The specific embodiment
Below in conjunction with view the present invention is described in detail, this embodiment can make the professional and technical personnel more understand the present invention, but does not limit the present invention in any form.
The present invention is a kind of elevator energy consumption method for comprehensive detection designed according to the mode of operation of existing elevator, with the standby energy consumption of unit time as elevator energy consumption based measurement energy consumption, the energy consumption of elevator is carried out the category measurement statistics, with the state before each state variation is frame of reference, the energy consumption that at every turn changes is carried out statistic of classification, promptly with the aggregate-value E1 of the energy consumption measurement before changing as frame of reference, the aggregate-value E2 that changes the back energy consumption measurement is carried out subtraction with the aggregate-value E1 that changes preceding energy consumption measurement, the result is deducted the standby energy consumption of unit time and the product of this variation Δ perdurability t again, just draw the energy consumption of this kind state variation, described standby energy consumption is meant that elevator is static, but the illumination of elevator and the ventilation system elevator energy consumption when starting.
For different elevators different classification is arranged, as: elevator is divided into two kinds of delivery energy consumption and characteristic energy consumptions.
Maybe will deliver energy consumption divides thin for delivering up energy consumption, delivering descending energy consumption, the characteristic energy consumption is subdivided into no-load power consumption, door function consumption, stops terraced energy consumption, with the delivery energy consumption of statistics distance and the weight delivery energy consumption that obtains unit weight and distance, the no-load power consumption of statistics is obtained the no-load power consumption of unit distance divided by the distance of operation divided by delivery.
The carriage lift energy consumption can also be subdivided into again: be divided into the up electronic energy consumption of delivery according to the load difference, deliver up generating energy consumption, delivery downlink electrical kinetic energy consumption, deliver descending generating energy consumption, the characteristic energy consumption is subdivided into again: unloaded up generating energy consumption, unloaded downlink electrical kinetic energy consumption, door function consumption, standby energy consumption and dormancy energy consumption, with the delivery energy consumption of statistics distance and the weight delivery energy consumption that obtains unit weight and distance divided by delivery, the no-load power consumption of statistics is obtained the no-load power consumption of unit distance divided by the distance of operation, described standby energy consumption is meant that elevator is static, but the illumination and the ventilation system of elevator are started, described dormancy energy consumption is meant that elevator is static, the illumination and the ventilation system of elevator quit work, and basic control circuit are only arranged in work.
Now simple analysis is carried out in the measurement of several energy consumptions
The elevator standby energy consumption e of measuring unit's time at first, standby energy consumption is meant that elevator is static, but the elevator energy consumption the when illumination of elevator and ventilation system are started, this is a most basic state of elevator, the accumulative total E1 that the elevator readiness for action is initially obtained electric energy carries out recorded and stored, and as the energy consumption radix, the accumulative total E2 of the electric energy that the standby end is obtained deducts this energy consumption radix E1 again, divided by standby time Δ t, thereby obtain the elevator standby energy consumption e of unit time
This energy consumption is the relative fixed unmodified for every elevator, therefore can according to statistical needs limited number of time measure as measure for 3～20 times take the mean after, just no longer measured, store as the basic energy consumption of other energy consumption measurement of elevator.
When zero load was up, the aggregate-value E1 of energy consumption measurement carried out record with moving just, writes down the aggregate-value E2 of end of run energy consumption measurement again, and the difference that the latter is deducted the former deducts the elevator standby energy consumption of unit time and the product of time of run again, must up total energy consumption
E＝E2-E1-e×Δt
The feedback function if this elevator does not generate electricity, what obtain is positive number, if this elevator has the generating feedback function, what obtained this moment is negative, the numerical value bright elevator no-load power consumption of novel index more is excellent more, same unloaded descending, the electric energy E1 that operation is just added up energy consumption measurement carries out record, write down the electric energy E2 of end of run accumulative total energy consumption measurement again, the difference that the latter is deducted the former deducts the elevator standby energy consumption e of unit time and the product of time of run Δ t again, can get the result, for the statistical parameter of each escalator has comparability, we obtain the no-load power consumption of statistics the no-load power consumption of unit distance divided by the distance of operation.
The method of measurement of delivery energy consumption is with above-mentioned also identical, and just the statistical parameter for each escalator has comparability, the delivery energy consumption that the delivery energy consumption that we will add up obtains unit weight and distance divided by the distance that delivers and weight.
Door function consumption is that the energy consumption of switch after in front of the door deducted the elevator standby energy consumption e of unit time and the product of door machine time of run Δ t, just obtains a function consumption, and the energy consumption of door machine also is basic unmodified, can no longer measure through after the measurement of limited number of time.
E＝E2-E1-e×Δt
The dormancy energy consumption, this is the most basic energy consumption of elevator, because just the part elevator just has such design at present, temporarily can not be general, so can not be used for checking system as basic energy consumption, in case this fuel saving design becomes the elevator indispensability in the future, also can it as the basic energy consumption of this checking system, the energy consumption aggregate-value E2 that enters after first energy consumption aggregate-value E1 of this state and state finish is subtracted each other, time Δ t divided by state continuance, get the dormancy energy consumption of unit time, the energy consumption of its in unit time also is basic unmodified, through can no longer measuring after the measurement of limited number of time, it is the illumination of elevator and the energy consumption of ventilation system that the elevator standby energy consumption of it and unit time subtracts each other what draw, and this also is a kind of metastable energy consumption.
With this method of inspection is guidance, and we have designed following energy consumption comprehensive detector:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, it mainly is by main website 15, slave station 7, these three of elevator run signal pick-up transducers are partly formed, main website has LCD MODULE 31, power module 32, treater 33, radio receiving transmitting module 34, electric energy detection module 35, the I/O interface, time meter, slave station 7 is by power module 41, signal processor 42, radio receiving transmitting module 46, the I/O interface is formed, described elevator run signal pick-up transducers comprises: band-type brake detecting sensor 13, speed rang sensor 10, current transformer 16, the gate detecting sensor, photosensor 21, elevator load detection sensor 9, the gate detecting sensor is divided into the detecting sensor 3 of opening the door again, the detecting sensor 2 of closing the door, the I/O interface of main website 15 comprises band-type brake detecting sensor interface 38, speed rang sensor interface 37, current transformer interface 36, respectively with band-type brake detecting sensor 13, speed rang sensor 10, current transformer 16 joins, the I/O interface of slave station 7 comprises: gate detecting sensor interface 45, photosensor interface 44, elevator load detection sensor interface 43, respectively with the gate detecting sensor, photosensor 21, elevator load detection sensor 9 is joined, main website 15 receives from band-type brake detecting sensor 13, speed rang sensor 10, the data of current transformer 16 and slave station 7 pass through wireless transmission data, and data are analyzed the computing storage.
As Fig. 2, shown in Figure 3, the detecting sensor of opening the door 3 is installed on the end of lift car fixed mount 22, the detecting sensor of closing the door 2 is installed on lift car fixed mount 22 middle parts, the flat thin magnet 1 that matches with the detecting sensor 3 of opening the door, the detecting sensor of closing the door 2 is installed on the elevator cage door top, close behind the door and detecting sensor 2 corresponding sections of closing the door, the top cage illumination lamp 20 that photosensor 21 is installed in the car is other.
As shown in Figure 6, elevator load detection sensor 9 is fixed on the bearing 24, upper fixed has supporting 25, one adjustable pressing plate 26 is arranged at the middle part of bearing 24, line of centers with pressing plate 26 is an axis of symmetry, the other end at bearing 24 also is fixed with a supporting 25, use when installing, transfer loose pressing plate 26 elevator wire rope 18 to be put into the top of two supportings 25, in the space of pressing plate 26 belows, regulating pressing plate 26 is pressed on steel rope in two supportings up and down, elevator load detection sensor 9 just has been fixed on the elevator wire rope 18 like this, and pressing plate 26 is pressed on steel rope 18 in the supporting at two ends by bolt, forms 3 force way.
After installing, steel rope through load detecting device shape in an angle, its force diagram as shown in Figure 7, tension force F is consistent with steel rope axis direction, because angle exists, produces a resultant radial force P.Do not considering the own elastic deformation of external factor and steel rope, the measurement mechanism force analysis is as follows: make a concerted effort to exist between P and the F following relation, promptly
Last lower support diametral load is half of the P that makes a concerted effort, and size is
The suffered power of pressure sensor is the suffered diametral load of upper support just, and the survey sensor signal changes, and just can calculate steel wire rope tension.
Principle of work of the present invention is: the elevator standby energy consumption of the unit time after this detector installs under advanced pedestrian's industry control system detects
1, the method for measurement of the elevator standby energy consumption e of unit time:
1) the elevator band brake apparatus is in band-type brake state (band-type brake detecting sensor);
2) the cage illumination lamp is in "on" position (photosensor);
3) elevator cage door is in closed condition (detecting sensor of closing the door);
When the above three kinds of states of detection exist simultaneously, the system start-up time meter begins to calculate the elevator standby time, and the aggregate-value E1 that the electric energy that while master station processor 33 generals electric energy detection module is this moment detected uses stores the electric energy criterion numeral as energy consumption measurement under the elevator readiness for action; Master station processor obtains in real time the aggregate-value E2 of electric energy from the electric energy detection module under the elevator readiness for action, and the accumulative total of the electric energy obtained is deducted the electric energy criterion numeral, divided by standby time Δ t, thereby obtains the elevator standby energy consumption of unit time
This energy consumption is the relative fixed unmodified for every elevator, therefore can measure as 3～20 times or more times measurement at limited number of time according to statistical needs, after taking the mean, just no longer measured, stored as the basic energy consumption of other energy consumption measurement of elevator.
2, the method for measurement of the elevator dormancy energy consumption of unit time:
1) the elevator band brake apparatus is in band-type brake state (band-type brake detecting sensor);
2) elevator cage door is in closed condition (detecting sensor of closing the door);
3) the cage illumination lamp is in off-position (photosensor);
When the above three kinds of states of detection exist simultaneously, the time meter of system start-up host computer control treater begins to calculate the elevator dormancy time, and the aggregate-value E1 that the electric energy that while master station processor 33 generals electric energy detection module is this moment detected uses stores the electric energy criterion numeral as energy consumption measurement under the elevator dormant state; Master station processor obtains in real time the aggregate-value E2 of electric energy from the electric energy detection module under the elevator dormant state, and the accumulative total of the electric energy obtained is deducted the electric energy criterion numeral, divided by dormancy time Δ t, thereby obtains elevator dormancy energy consumption in the unit time
This energy consumption is the relative fixed unmodified for every elevator, therefore can be after the limited number of time measurement be taken the mean, just no longer measured, it is the illumination of elevator and the energy consumption of ventilation system that the elevator standby energy consumption of it and unit time subtracts each other what draw, this also is a kind of metastable energy consumption, but only there is being the part elevator that this function is arranged at present, in case this fuel saving design becomes the elevator indispensability in the future, also can it as the basic energy consumption of this checking system, be applied to the parameter use as a comparison of other state of elevator, the comprehensive state of all elevators at present of this detector just can detect when elevator has this function, if do not have this function with regard to free of data.
3, the method for measurement of elevator door-motor energy consumption:
1) the elevator band brake apparatus is in band-type brake state (band-type brake detecting sensor);
2) the elevator detecting sensor of closing the door is in its unaccessed state;
The 3 elevators detecting sensor of opening the door is in its unaccessed state;
When the above three kinds of states of detection exist simultaneously, expression door machine is (work of door machine is to be detected jointly by the detecting sensor of opening the door, the detecting sensor of closing the door) in working order, the beginning of representing to open the door of the detecting sensor of closing the door falling edge, the end of representing to open the door of the detecting sensor of opening the door positive rise, the beginning of representing to close the door of the falling edge of the detecting sensor of opening the door, the positive rise of the detecting sensor of the closing the door end of representing to close the door.The detecting sensor signal is successively in the process of once opening the door normally: the detecting sensor of the closing the door falling edge-detecting sensor of opening the door positive rise, the detecting sensor signal is successively in the process of closing the door: the positive rise of the falling edge of the detecting sensor of the opening the door-detecting sensor of closing the door, occur not according to switch detecting sensor signal cycle rule in the process if close the door, as close the door and do not finish to open the door again, system detects data with this time and is judged as invalid data, and is rejected.In the normal switch door process, the system start-up time meter calculates the elevator door-motor time of run, and the energy consumption aggregate-value E1 that while master station processor general electric energy detection module is this moment detected stores the electric energy criterion numeral as energy consumption measurement under the elevator switch door state; Master station processor obtains the aggregate-value E2 of energy consumption in real time from the electric energy detection module under the elevator door-motor mode of operation, and the E2 that obtains is deducted E1, deducts an elevator unit time standby energy consumption and the product of machine time of run Δ t again
E＝E2-E1-e×Δt
Thereby obtain a machine and open once or close the once energy consumption of door; This energy consumption is the relative fixed unmodified for every elevator, therefore can just no longer measure after the limited number of time measurement is taken the mean.
4, the method for measurement of unit distance elevator no-load power consumption:
1) the elevator band brake apparatus is in the state of opening a sluice gate (band-type brake detecting sensor);
2) coder of speed rang sensor is in slew mode (speed rang sensor);
3) load detection sensor detection car is in light condition;
When the above three kinds of states of detection exist simultaneously, the system start-up time meter begins to calculate elevator no-load run time Δ t, pulse count according to the encoder feedback of speed rang sensor is calculated range ability L, detect car load according to elevator load detection sensor device, judge whether to be in light condition, detect ascending for elevator or descending service direction according to the direction of the encoder feedback of speed rang sensor.The aggregate-value E1 that the electric energy that while master station processor general electric energy detection module is this moment detected uses stores the electric energy criterion numeral as energy consumption measurement under the elevator light condition; Master station processor obtains the aggregate-value E2 of electric energy in real time from the electric energy detection module under the elevator light condition, and the aggregate-value E2 of the electric energy obtained deducted the poor of above-mentioned electric energy criterion numeral E1, deduct the product of elevator unit time standby energy consumption e and time of run Δ t again, thereby obtain the power consumption under the current state.
E＝E2-E1-e×Δt
Power consumption under the current state is that positive number represents that elevator is in motoring condition, and the power consumption under the current state is that the negative number representation elevator is in generating state; Can realize the detection of elevator no-load power consumption in conjunction with the elevator service direction, as the up generator operation energy consumption of zero load, descending electronic operation energy consumption etc.; For the statistical parameter of each escalator has comparability, we calculate resulting unloaded Top Runby and unloaded Bottom Runby L divided by the pulse count according to the encoder feedback of speed rang sensor respectively with the up generator operation energy consumption of zero load, descending electronic operation energy consumption, thereby obtain the unloaded descending electronic operation energy consumption of the unloaded up generator operation energy consumption and the unit distance of unit distance
This energy consumption is the relative fixed unmodified for every elevator, therefore can just no longer measure after the limited number of time measurement is taken the mean.
5, the carriage lift energy consumption R method of measurement of unit weight distance:
1) the elevator band brake apparatus is in the state of opening a sluice gate (band-type brake detecting sensor);
2) coder of speed rang sensor is in slew mode (speed rang sensor);
3) load detection sensor detection car is in non-light condition;
When the above three kinds of states of detection exist simultaneously, the system start-up time meter calculates the delivery time of elevator, pulse count according to the encoder feedback of speed rang sensor is calculated range ability L, detect car load m according to elevator load detection sensor device, detect ascending for elevator or descending service direction according to the direction of the encoder feedback of speed rang sensor.The aggregate-value E1 of master station processor electric energy detection electric energy that module detects use this moment simultaneously stores the electric energy criterion numeral as energy consumption measurement under the carriage lift state; Master station processor obtains the accumulative total of electric energy in real time from the electric energy detection module under the carriage lift state, and the aggregate-value E2 of the electric energy obtained deducted above-mentioned electric energy criterion numeral E1, deduct the product Δ t of elevator unit time standby energy consumption e and time of run again, thereby obtain the power consumption E under the current state
