Good parameter is determined as taking rate priority threshold.
Handling process such as Fig. 3 of the internal functional blocks of the energy response arithmetic section 103 shown in Fig. 2
Shown in.
(ascent direction takes rate priority threshold ρE(UP))
FC100 to FC107 is to take rate priority threshold ρ for computing ascent directionE(UP) place
Reason.
In FC100, to the E representing power consumption minimaminInitialize.At this point it is possible to
Value the biggest compared with the power consumption value supposed is given as initial value.
In FC101, by parameter setting section 1031, rate parameter ρ will be taken and be initialized as 0.
In FC102, calculate the power consumption taken when rising when rate is ρ (0～100%) travels
E(ρ).Wherein it is possible to by following formula (1) rough calculation E (ρ).For example, it is possible to rough calculation is taken
Each E (ρ) of change in units of 1% of rate ρ, and preserve.
E (ρ)=Pacc(ρ)×Tacc/2+Pconst(ρ)×Tconst+Pdcc(ρ)×Tdcc/2 …(1)
In formula, Pacc(ρ) consumption electric power when giving it the gun, T are representedaccRepresent and give it the gun the time,
Pconst(ρ) consumption electric power during constant speed drive, T are representedconstRepresent constant speed drive time, Pdcc(ρ)
Represent consumption electric power during Reduced Speed Now, TdccRepresent the Reduced Speed Now time.
Furthermore, it is possible to by following formula (2) rough calculation Pacc(ρ)、Pconst(ρ)、Pdcc(ρ) take
Rate is consumption electric power P (ρ) during ρ.
P (ρ)={ (J × 2 × KR×α)/Ds+(Mca+MRL×ρ/100-MCW+Mloss)×DS
×g/(2×KR)}×V×KR×2/(60×Ds)×η …(2)
In formula, J represents moment of inertia (moment), and α represents acceleration, McaRepresent car weight,
MRLRepresent payload ratings, MCWRepresent the weight of balance weight, MlossRepresent and exercise loss, DSTable
Showing the diameter of rope sheave, V represents travel speed, and acceleration alpha is 0 when constant speed, when accelerating be+
Acceleration, slow down time be-acceleration.Additionally, KRIt is by roping (roping) mode (elevator
The winding method of the steel wire rope of car and balance weight) coefficient that determines, such as, KRWhen=2, expression is adopted
By the roping mode of 2: 1, act on the load when load on hoist cable is the roping mode of employing 1: 1
1/2.
J can carry out rough calculation according to following formula (3).
J=M × DS 2/(4×KR)+JR …(3)
In formula, JRRepresenting the moment of inertia of rotary system, M can be carried out roughly according to following formula (4)
Calculate.
M=(Mca+MRL×ρ/100+MCW)/KR+(Mrp+Mtal)×H/(2×KR) …(4)
In formula, MrpRepresent the weight of the per unit length of hoist cable, MtalRepresent each list of stern fast
The weight of bit length, H represents operating range.
Additionally, in formula (2), η represents efficiency, when carrying out operation power, η=1/ (ηm×
ηinv), when carrying out regeneration and running, η=ηm×ηinv。ηmAnd ηinvRepresent motor respectively
Efficiency and the efficiency of inverter.
According to the data being stored in car and building specification data storage part 101, by formula (1)
To formula (4), it is possible to rough calculation goes out to take the power consumption E (ρ) when rising when rate is ρ travels.Will
Operating range H is set as the distance making elevator sufficiently achieve needed for normal speed.
In FC103, by power consumption minima Emin| E (ρ) | with the absolute value representing E (ρ)
Compare, if | E (ρ) | is less, then in FC104, update EminRear entrance FC105, |
E (ρ) | equal to or more than EminTime, it is directly entered FC105.
In FC105, if ρ is less than 100, then enter FC106, after ρ adds 1, return FC102,
Calculate the power consumption E (ρ) under new ρ.If ρ is more than 100, then enter FC107.
In FC107, take rate priority threshold ρ as ascent directionE(UP), select at FC104
In carried out the E of final updatedmin。
FC108 to FC115 is that computing descent direction takes rate priority threshold ρE(DOWN) place
Reason.Owing to this process and ascent direction take rate priority threshold ρE(UP) computing is roughly the same, institute
Only to illustrate that at this rate of taking in FC110 is for declining the thick of power consumption E (ρ) when travelling during ρ
Slightly computational methods.When declining traveling, E (ρ) can pass through following formula (5) and carry out rough calculation.
E (ρ)=Pacc(ρ)×Tacc/2+Pconst(ρ)×Tconst+Pdcc(ρ)×Tdcc/2 …(5)
Following formula (6) can be passed through carry out roughly additionally, rate of taking is consumption electric power P (ρ) during ρ
Calculate.
P (ρ)={ (J × 2 × KR×α)/DS-(Mca+MRL×ρ/100-MCW-Mloss)×DS
×g/(2×KR)}×V×KR×2/(60×DS)×η …(6)
Here, J is identical with formula (3).
According to the data being stored in car and building specification data storage part 101, by formula (3)
To formula (6), it is possible to rough calculation goes out to take the power consumption E (ρ) when decline when rate is ρ travels.
Pass through said method, it is possible to calculate ascent direction and take rate priority threshold ρE(UP) and under
Rate priority threshold ρ is taken in fall directionE(DOWN).In the above description, formula (1) to formula (6) is used
Carry out computing but it also may the weight of hoist cable and stern fast is assumed to 0, is assumed to by car weight
The constant times of payload ratings, is assumed to the weight of balance weight the constant times etc. of payload ratings, is thus
Calculate power consumption simply.Additionally, by FC101 and FC109, FC105 and FC113,
The hunting zone of rate of the taking priority threshold of ascent direction and descent direction is set as rate of taking 0% to
100% but it also may rate of taking priority threshold during ascent direction is set as 30% to 50%, and
Rate of taking priority threshold during descent direction is set as 50% to 70%, therefore can also in advance only
Scan within the range.
Fig. 4 represents the power consumption phase of the ascent direction calculated by above method and descent direction
For taking the variation characteristic of rate.
As shown in Fig. 4 (a), in the variation characteristic of the power consumption when ascent direction, it is less than in the rate of taking
ρE(UP) time, power consumption is less than 0, the most now carries out regeneration and runs, and namely carries out sending out
Electricity.If rate of taking is more than ρE(UP), then carry out operation power, namely need to consume electric power.As
Shown in Fig. 4 (a), ρE(UP) represent that rising power consumption when travelling takes rate when being zero.Take rate
For ρE(UP) size of the slope of power consumption during left and right and rate of taking are more than ρE(UP) power consumption time
Varying in size of the slope of amount, rate of taking is more than ρE(UP) slope of power consumption time becomes big.Therefore,
If the rate of taking having passenger, i.e. lift car in lift car rises, then rise power consumption when travelling
Can increase, now, with rate of taking less than ρE(UP) increments of power consumption time is compared, and takes rate
More than ρE(UP) increments of power consumption time is bigger.
On the other hand, as shown in Fig. 4 (b), in the variation characteristic of the power consumption when descent direction,
Rate of taking is less than ρE(DOWN) time, power consumption becomes more than 0, carries out operation power.If taking
Rate is more than ρE(DOWN), then carry out regeneration to run.As shown in Fig. 4 (b), ρE(DOWN) represent
Decline travel time power consumption vanishing time take rate.The rate of taking is ρE(DOWN) consumption during left and right
The size of the slope of electricity and rate of taking are less than ρE(DOWN) size of the slope of power consumption time is not
With, rate of taking is less than ρE(DOWN) slope of power consumption time becomes big.Therefore, if lift car
In have the rate of taking of passenger, i.e. lift car to rise, then decline travel time power consumption reduce, now,
With rate of taking more than ρE(DOWN) decrement time is compared, and rate of taking is less than ρETime (DOWN)
The decrement of power consumption is bigger.
(Energy efficiency evaluation function sets part 105)
In Energy efficiency evaluation function sets part (or alternatively referred to as evaluation index function sets part) 105
In, set Energy efficiency evaluation according to rate of the taking priority threshold calculated by energy response arithmetic section 103
Function.
Fig. 5 represents the Energy efficiency evaluation function of the de novo hall call for ascent direction, Yi Jizhen
Energy efficiency evaluation function to the de novo hall call of descent direction.Here, the Energy efficiency evaluation in figure
Index refer to determine corresponding with de novo hall call when distributing car about energy-conservation index,
Such as, this can be set as the value of 1 to 100.Energy efficiency evaluation refers to that target value is the least, and energy-efficient performance is just
It is the highest, so lift car little for Energy efficiency evaluation desired value is set as being easier to the car of distribution.
As it is shown in figure 5, take in ascent direction and descent direction rate all take rate priority threshold with
Time lower, Energy efficiency evaluation index diminishes.As shown in Figure 4, in ascent direction, rate of taking is taking rate
Time below priority threshold, the increments of power consumption during distribution is less, and in descent direction, takes
Rate is when taking below rate priority threshold, and the decrement of power consumption during distribution is bigger.Therefore, pass through
Preferential these lift cars of distribution, it is possible to make the summation of the power consumption of lift car entirety become minimum.
Additionally, in Figure 5, in rate of taking is less than the region taking rate priority threshold, take rate more
Close to taking rate priority threshold, Energy efficiency evaluation index is the least.This is because taking rate less than taking
In the region of rate priority threshold, take, by preferential distribution, the lift car that rate is high, thus it is low to take rate
Lift car for distribution situation reduce and be in halted state, the most unnecessary traveling subtracts
Few, it is possible to realize energy-conservation.
On the other hand, as shown in Figure 4, when ascent direction, rate of taking is taking rate priority threshold
It is relatively big that above lift car distributes to during de novo hall call the increments of power consumption, and under
During fall direction, distribute to de novo door by taking rate at the lift car taking more than rate priority threshold
During the calling of the Room, the decrement of power consumption is less.Accordingly, with respect to de novo hall call, preferentially will
Rate of taking is taking the lift car of below rate priority threshold for distributing, therefore, at ascent direction and
When taking rate in descent direction for taking more than rate priority threshold, the Energy efficiency evaluation index of Fig. 5 all becomes
Greatly.
It is to say, as it is shown in figure 5, in ascent direction and descent direction, Energy efficiency evaluation index exists
Take in rate is more than the region taking rate priority threshold and be set more preferential less than taking rate than rate of taking
The region of threshold value is big, becomes along with taking the function that rate rises and Energy efficiency evaluation index increases.Thus,
The summation that can make the power consumption of lift car entirety realizes minimizing.
Additionally, in Figure 5, taking rate more than the region taking rate priority threshold, taking rate the biggest
In taking rate priority threshold, Energy efficiency evaluation index is the highest.Its reason is, is taking rate more than taking
In the region of rate priority threshold, by preferentially being used for distributing by lift car low for rate of taking, thus point
The power consumption of timing diminishes.Further, also a reason is to take, by distribution, the elevator car that rate is high
Railway carriage or compartment, prevents the situation that only specific lift car becomes crowded.
As it has been described above, it is each according to be stored in advance in car and building specification data storage part 101
Plant parameter, calculate in energy response arithmetic section 103 and take rate priority threshold, and comment energy-conservation
Valency function sets part 105 sets Energy efficiency evaluation function.It addition, be stored in advance in car and building

Deng storage device in.Hereafter, be stored in car and building specification data storage part 101 in each
In the case of kind of parameter there occurs change, again carry out energy response arithmetic section 103 takes rate
