According to the data that are stored in car and building specification data storage area 101, through type (1) is to formula (4), the consumption of current E (ρ) when the rising when can rough calculation going out to take rate and being ρ is travelled.Be set as making elevator fully to reach the required distance of command speed operating range H.

According to the data that are stored in car and building specification data storage area 101, through type (3) is to formula (6), the consumption of current E (ρ) when the decline when can rough calculation going out to take rate and being ρ is travelled.
By said method, can calculate ascent direction and take rate priority threshold ρ
e(UP) and descent direction take rate priority threshold ρ
e(DOWN).In the above description, employing formula (1) to formula (6) has been carried out computing, but also the weight of hoist cable and stern fast can be assumed to 0, car weight is assumed to the constant times of payload ratings, the weight of counterbalanced weight is assumed to the constant times of payload ratings etc., thus for calculating simply consumption of current.In addition, by FC101 and FC109, FC105 and FC113, the search coverage of the rate of the taking priority threshold of ascent direction and descent direction is set as taking rate 0% to 100%, but the rate of the taking priority threshold in the time of also can be by ascent direction is set as 30% to 50%, and the rate of the taking priority threshold during by descent direction is set as 50% to 70%, therefore also can only within the scope of this, search in advance.
Fig. 4 represents that the consumption of current of the ascent direction that calculates by above method and descent direction is with respect to the variation characteristic of taking rate.
As shown in Fig. 4 (a), in the variation characteristic of the consumption of current when ascent direction, in the rate of taking, be less than ρ
e(UP) time, consumption of current is below 0, and the operation of namely now regenerating, namely generates electricity.If the rate of taking surpasses ρ
e(UP), carry out operation power, namely need power consumption.As shown in Fig. 4 (a), ρ
e(UP) rate of the taking when consumption of current that expression is risen while travelling is zero.The rate of taking is ρ
e(UP) size of the slope of consumption of current during left and right with take rate and be greater than ρ
e(UP) varying in size of the slope of consumption of current time, the rate of taking is greater than ρ
e(UP) it is large that the slope of consumption of current time becomes.Therefore,, if having passenger in lift car, be that the rate of taking of lift car rises, the consumption of current rising while travelling can increase, and now, is less than ρ with the rate of taking
e(UP) recruitment of consumption of current time is compared, and the rate of taking is greater than ρ
e(UP) recruitment of consumption of current time is larger.
On the other hand, as shown in Fig. 4 (b), in the variation characteristic of the consumption of current when descent direction, in the rate of taking, be less than ρ
e(DOWN) time, consumption of current becomes more than 0, carries out operation power.If the rate of taking surpasses ρ
e(DOWN), the operation of regenerating.As shown in Fig. 4 (b), ρ
e(DOWN) rate of taking while represent declining consumption of current vanishing while travelling.The rate of taking is ρ
e(DOWN) size of the slope of consumption of current during left and right with take rate and be less than ρ
e(DOWN) varying in size of the slope of consumption of current time, the rate of taking is less than ρ
e(DOWN) it is large that the slope of consumption of current time becomes.Therefore,, if having passenger in lift car, be that the rate of taking of lift car rises, the consumption of current while travelling that declines reduces, and now, is greater than ρ with the rate of taking
e(DOWN) reduction time is compared, and the rate of taking is less than ρ
e(DOWN) reduction of consumption of current time is larger.
(Energy efficiency evaluation function setting section 105)
In Energy efficiency evaluation function setting section (or also can be described as critical for the evaluation function setting section) 105, according to the rate of the taking priority threshold being calculated by energy response arithmetic section 103, set Energy efficiency evaluation function.
Fig. 5 represents for the Energy efficiency evaluation function of the de novo hall call of ascent direction and for the Energy efficiency evaluation function of the de novo hall call of descent direction.At this, the Energy efficiency evaluation index in figure refer to while determining to distribute car accordingly with de novo hall call about energy-conservation index, for example, this can be set as 1 to 100 value.Energy efficiency evaluation refers to that target value is less, and energy-efficient performance is just higher, so the car that the little lift car of Energy efficiency evaluation desired value is set as more easily distributing.
As shown in Figure 5, the rate of taking in ascent direction and descent direction is all being taken rate priority threshold when following, and Energy efficiency evaluation index diminishes.As shown in Figure 4, in ascent direction, the rate of taking is being taken rate priority threshold when following, and the recruitment of the consumption of current of minute timing is less, and in descent direction, and the rate of taking is being taken rate priority threshold when following, and the reduction of the consumption of current of minute timing is larger.Therefore,, by these lift cars of priority allocation, can make the summation of the consumption of current of lift car integral body become minimum.
In addition, in Fig. 5, in the rate of taking is less than the region of taking rate priority threshold, the more approaching rate priority threshold of taking of the rate of taking, Energy efficiency evaluation index is just less.This is because be less than in the region of taking rate priority threshold in the rate of taking, by priority allocation, take the lift car that rate is high, thereby the lift car that the rate of taking is low reduces for the situation of distributing and in halted state, the unnecessary minimizing of travelling, can realize energy-conservation thus.
On the other hand, as shown in Figure 4, when ascent direction, the recruitment of consumption of current is larger when taking the lift car of rate more than taking rate priority threshold and distribute to de novo hall call, and when descent direction, the reduction of consumption of current is less when taking the lift car of rate more than taking rate priority threshold and distribute to de novo hall call.Therefore, with respect to de novo hall call, preferentially by taking rate, taking lift car below rate priority threshold for distributing, therefore, the rate of taking in ascent direction and descent direction is for taking rate priority threshold when above, and the Energy efficiency evaluation index of Fig. 5 all becomes large.
That is to say, as shown in Figure 5, in ascent direction and descent direction, Energy efficiency evaluation index is set to such an extent that than the rate of taking, be less than that to take the region of rate priority threshold large in the rate of taking is greater than the region of taking rate priority threshold, becomes along with the rate of taking rises and function that Energy efficiency evaluation index increases.Thus, can make the summation realization of the consumption of current of lift car integral body minimize.
In addition, in Fig. 5, be greater than the region of taking rate priority threshold in the rate of taking, the rate of taking is more greater than takes rate priority threshold, and Energy efficiency evaluation index is just higher.Its reason is, in the rate of taking is greater than the region of taking rate priority threshold, by preferentially by the low lift car of the rate of taking for distributing, thereby the consumption of current of minute timing diminishes.And, also have a reason to be, by distribution, take the lift car that rate is high, prevent the situation of only having specific lift car to become crowded.
As mentioned above, according to pre-stored various parameters in car and building specification data storage area 101, in energy response arithmetic section 103, calculate and take rate priority threshold, and set Energy efficiency evaluation function in Energy efficiency evaluation function setting section 105.In addition, pre-stored various parameters in car and building specification data storage area 101 are stored during in elevator setting, the computing of the rate of the taking priority threshold in energy response arithmetic section 103 and the Energy efficiency evaluation function in Energy efficiency evaluation function setting section 105 also when elevator setting by computing and setting, and be stored in the memory storages such as memory device of each several part.After this, in the situation that change has occurred the various parameters that are stored in car and building specification data storage area 101, again carry out the computing of the rate of the taking priority threshold in energy response arithmetic section 103 and computing and the setting of the Energy efficiency evaluation function in Energy efficiency evaluation function setting section 105.
Below, return to Fig. 1 and proceed explanation.
(car and each layer of elevator lobby information part 100)
First, in car and each layer of elevator lobby information part 100, collect from the state of each lift car of each monomer elevator control setup 21A～21C and hall call register device 3A, 3B input, the number information of the upper and lower elevator of passenger of the state of the elevator lobby of each floor and each floor etc.In the state of elevator lobby of each floor and the number information of the upper and lower elevator of passenger of each floor, except the information of the calling of hall call register device 3A, the 3B input that indicates to have no way of, can also comprise and represent to have or not the information of the hall call that the wheelchair user of hall call register device (not shown) input of using from wheelchair user carries out or surveillance camera etc. to the determination information of the degree of crowding in lift car etc.In addition, as the passenger's of each floor the number information of elevator up and down, also can use investigation in advance to or the average upper and lower elevator number of each floor of obtaining as actual mean value.
(prediction arrives temporal calculation part 102)
In prediction, arrive in temporal calculation part 102, according to the state of each lift car, the state of the elevator lobby of each floor, the upper and lower number information of the elevator of each floor that collect in car and each layer of elevator lobby information part 100, the speed of lift car in car and building specification data storage area 101 of being stored in, the number of floor levels in building and interlayer spacing etc., for each lift car, infer that union goes out the time each lift car arrives each floor for the hall call of all directions of each floor being provided to service till.
(number arithmetic section 104 in prediction car)
In prediction car number arithmetic section 104 according to the car call information of passing through action button operation in car of each lift car of being collected by car and each layer of elevator lobby information part 100, the hall call information of number, each floor in the current car of each lift car, arrived prediction time of advent of each lift car that temporal calculation part 102 calculates by prediction, number in the car of each lift car while calculating the hall call layer from new registration.In the situation that from the current location of lift car till have car call or distribute to the hall call of car or distributed the hall call of new registration to car the floor of the hall call layer of arrival new registration temporarily, according to these, call out, be added or deduct the number in lift car.
The addition number relevant with hall call now can be used fixed value, if for example entrance floor is added 3 and takes advantage of into passenger, if general floor is added 1, take advantage of into passenger etc., also can predict that the product of the time of advent is obtained with the hall call of each floor according to the learning value of the upper and lower number of elevator of the time per unit of each floor of past and lift car and take advantage of into number accordingly.With according to car call and the number of lower elevator deducts the value that number can be used the number in lift car to obtain divided by car call number accordingly, also can use the value of having distributed the number in car to obtain according to the ratio of the learning value of the number of elevator up and down of the time per unit of each floor in past.
(rate arithmetic section 106 is taken in prediction)
In prediction, take in rate arithmetic section 106, according in prediction car, calculate in number arithmetic section 104 the hall call layer from new registration time prediction car in number and be stored in car and building specification data storage area 101 the specified seating capacity of car, rate is taken in the prediction while calculating the hall call layer from new registration.
(Energy efficiency evaluation index arithmetic section 108)
In Energy efficiency evaluation index arithmetic section 108, according to the Energy efficiency evaluation function of setting in Energy efficiency evaluation function setting section 105, computing takes in prediction the Energy efficiency evaluation index that rate is taken in the prediction calculating in rate arithmetic section 106.
Then, the lift car with the rate of taking of this Energy efficiency evaluation index minimum is distributed as the corresponding lift car of the hall call with new registration.Thus, the rate of taking during for hall call layer from new registration is at the lift car of taking below rate priority threshold, can preferentially distribute or easily distribute, little or can preferentially be assigned with for the large lift car of reduction of the consumption of current that distributes for the recruitment of the consumption of current that distributes, can reduce thus the consumption of current of lift car integral body.
On the other hand, as shown in Figure 1, also can be arranged to, except Energy efficiency evaluation index, also other critical for the evaluation be made to consideration, and the corresponding lift car of the hall call with new registration is distributed.For example, as described below, the arithmetic section of the wait time critical for the evaluation arithmetic section of computing wait time critical for the evaluation or other critical for the evaluations of other critical for the evaluations of computing is set, and divide in the comprehensive evaluation index arithmetic section of comprehensive evaluation of timing carrying out lift car, determine the overall target of distributing.
(wait time critical for the evaluation arithmetic section 107)
Wait time critical for the evaluation arithmetic section 107 can be set, according to the hall call information of number, car call information, each floor in the car of each lift car of collecting and in prediction, arrive prediction time of advent of each floor of arrival calculating in temporal calculation part 102 in car and each layer of elevator lobby information part 100, calculate the wait time critical for the evaluation of each lift car.For example, can be according to the wait time of each lift car, the index of application 1～100.In addition, the wait time of being arranged to each lift car is shorter, and the wait time critical for the evaluation of each lift car is just less.For example, in the situation that 5 lift cars are carried out to unified management, can simplify, from the short lift car of wait time, sequentially give 20,40,60,80,100 index.
(arithmetic sections 109 of other critical for the evaluations)

Fig. 8 represents the calculated example of B.As shown in Fig. 8 (a), the value of A is set as to 2 seconds, ascent direction being taken to rate priority threshold and be set as 40%, for example, when wait time aviation value is 20 seconds, allow wait time to deteriorate into 23 seconds, the deterioration amount therefore wait time being allowed, is that wait time permissible value is set as 3 seconds.The aviation value of Energy efficiency evaluation desired value in the scope of taking rate 0% to 100% refer to wait time permissible value is consistent, and the area of the site part in Fig. 8 (b) is consistent with the area of site part in Fig. 8 (c).Now, can derive following formula (9).
40×2/2+60×2+60×(B-2)/2＝3×100 …(9)
By solving (9) formula, obtain B-2=4.7 second. therefore, the slope that the rate of taking is less than the Energy efficiency evaluation function while taking rate priority threshold is-2/40=-0.05 that the slope that the rate of taking is greater than the Energy efficiency evaluation function while taking rate priority threshold is 4.7/60=0.078.Therefore,, if the rate of taking is set as ρ %, the rate of taking is less than the Energy efficiency evaluation function phi while taking rate priority threshold
e(ρ) as shown in the formula (10).
Φ
E(ρ)＝-0.05×ρ+2 …(10)
In addition, take rate and be greater than the Energy efficiency evaluation function phi while taking rate priority threshold
e(ρ) as shown in the formula (11).
Φ
E(ρ)＝0.078×(ρ-40)+2＝0.078×ρ-1.12 …(11)
