Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an elevator installation planning device that proposes an appropriate elevator installation plan by calculating a substantial transport capacity for an elevator system in which a plurality of cars are used in one shaft. .
[0002]
[Prior art]
Usually, the selection of elevator equipment (number, speed, capacity) includes, for example, “traffic calculation” as described in “Guidelines for Elevator Planning for Building Design and Construction” (Japan) Elevator Association (1992). A calculation method called is used. This is a method of calculating the number of passengers that can be carried by the elevator within a unit time (usually 5 minutes) given a specific building specification and car specification (speed, capacity, etc.). A procedure for comparing the calculation result with the building resident population and determining the required number of elevators is generally adopted.
[0003]
An outline of the traffic calculation procedure will be described. FIG. 4 is a flowchart showing an outline of a traffic calculation procedure applied to a single deck (hereinafter, referred to as SD). First, in step S901, a car / building specification is input. The data input here include car speed / acceleration, capacity (number of people), door opening / closing time, number of building floors, number of service floors, floor height, and the like. For example, in the calculation model for an office building, it is assumed that all passengers get on the base floor (1F) and do not get on other floors. This is because the number of elevators capable of transporting a large amount of passengers generated at the time of commuting to the building (UP Peak) is calculated.
[0004]
In step S902, a predicted value (predicted number of stops) at which the car that has left the reference floor stops on the upper floor is calculated. This calculation formula is given by the following formula.
Fl = n {1- (1-1 / n) ^r }
Here, Fl: predicted number of stops, n: number of service floors excluding the base floor, r: car capacity (number of people)
[0005]
Next, in step S903, an acceleration time Ta, a local section traveling time Trl, and an express section traveling time Tre, which are the traveling time of the car, are calculated based on the above results. The specific calculation procedure is shown below. In the following, a local section is a section where passengers are sequentially disembarked, and is a section with a service floor. The other sections are called express sections.
Ta = V / α + t0
Trl = S1 / V + Ta × Fl
Tre = Se / V + Ta × Fe
Here, Sl: local section distance, Se: express section distance Fe: number of express section stops (2 when there is an express zone, 1 when there is no express zone)
[0006]
Then, in step S904, the boarding / alighting time Tp, the door opening / closing time Td, and the loss time Tl are calculated. The calculation procedure is shown below.
Td = td × (Fl + Fe)
Tp = tp × r
Tl = (Td + Tp) × 0.1
Here, Td: door opening / closing time per stop, Tp: getting on / off time per person.
In steps S905 and S906, a round trip time RTT and a 5-minute transport capacity HC per vehicle are calculated based on the calculation results up to step S904.
RTT = (Tr + Td + Tp + Tl)
HC = (300 × r) / RTT
[0008]
When the 5-minute transport capacity HC is obtained in this way, in step S907, the required number is determined. For example, when HC = 50 people / 5 minutes, if the traffic demand expected in the target building is 300 people / 5 minutes, the required number is calculated as 6 (300/50 = 6). Is done. The traffic demand is calculated as 2000 × 0.15 = 300 people / 5 minutes, for example, when it is assumed that the resident population of the building is 2000 people and 15% of them use the elevator in 5 minutes. The above is the description of the conventional traffic calculation procedure.
[0009]
[Problems to be solved by the invention]
However, the above calculation method is based on the case of a single deck (SD) in which one elevator is used for one shaft. Recently, a calculation method in which this calculation procedure is extended to a double deck has been adopted. However, when a plurality of elevators that operate independently on one shaft enter service (hereinafter, this is called a one-shaft multi-car, MC). At present, MC is still in the research stage, but if this system is put into practical use, traffic calculation and equipment planning methods based on it will be required as in the case of SD.
[0010]
The present invention has been made in view of the above points, and in an elevator system in which a plurality of cars are put into service in one shaft, the traffic calculation of MC and the facility planning based on the traffic calculation are performed in the same manner as in SD. It is an object to provide an elevator installation planning device as a tool that can be implemented.
[0011]

[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a block diagram illustrating an example of an overall configuration of an elevator facility planning device according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a multi-car equipment plan calculation device for deriving an equipment plan such as an appropriate car specification and number of vehicles for a one-shaft multi-car system, and 2 denotes a multi-car equipment plan calculation device. And a human I / F for inputting necessary data and outputting a result. Specifically, the multi-car facility plan calculation device 1 may be a board MPU manufactured exclusively, or may be a general-purpose computer such as a personal computer. The human I / F 2 is configured by devices such as a display and a keyboard.
[0015]
The multi-car construction plan calculation device 1 includes the following units 1A to 1E, and each of the units 1A to 1E is configured by software on the board MPU or a computer. . These are a standard database 1A storing data relating to standard elevator specifications, a zone division setting means 1B for automatically setting a plurality of service zone candidate plans for each car to be given priority service based on a given building specification, a standard database. Car data setting means 1C for setting specific car specifications from 1A, transportation capacity calculation means 1D for calculating a substantial transportation capacity per shaft based on the set building / car specification and service zone, zone division setting This is an optimal plan deriving means 1E for deriving an optimal service zone by comparing the actual transportation capacity calculated for each service zone candidate plan set by the means 1B.
[0016]
Further, the transport capacity calculating means 1D calculates the car orbiting time for each car for each car for each building specification / car specification data and the service zone candidate set by the zone division setting means 1B. The lap time of each car, which is the calculation result of the car lap time calculation means 1D1, is compared, and the lap time comparison / calculation means 1D2 and the lap time comparison / calculation means 1D2, which calculate the substantial lap time, are calculated based on the calculation results. The actual transport capacity calculating means 1D3 for calculating the actual transport capacity per shaft.
[0017]
Next, prior to the description of the operation in the embodiment of the present invention, the concept of calculating the transport capacity and the concept of the priority zone in the present invention will be described with reference to FIG. FIG. 2A is a diagram illustrating an example in which two cars are in service on one shaft of 1F-20F.
Here, it is assumed that 1F and 2F are the lower floor and the upper floor of the main car, respectively. The main floor is set to the second floor because the main floor is most congested, and it is considered that it is not efficient to alternately service the upper and lower two cars. This concept is also adopted for double decks, and depending on the destination floor, passengers are guided and requested to board the escalator after moving to the second floor.
[0018]
Since two cars are connected in the double deck, for example, passengers on “even floors” are guided and requested to get on from the second floor, but in the case of MC, each car operates independently. 2 (b) and 2 (c), the upper car is divided into upper and lower zones (lower car: 1-11F, upper car: 2F, 12F-20F in this example) and passengers bound for the upper zone start from the second floor. The method of getting on board is realistic. With this zone division, the transport capacity can be calculated for each of the upper car and the lower car using the conventional SD calculation procedure.
[0019]
However, what should be noted here is that the loss time caused by the interference between the upper and lower cars must be considered. Also, of course, the top floor of the lower car service zone is significantly lower than the top floor of the upper car, so the speed of the upper car must be at least equal to or higher than the lower car speed. In addition, since the car capacity affects the car size, it is desirable that the car capacity be equal in consideration of operating the same shaft. Here, in order to simplify the explanation, the case where two cars are put into service on one shaft has been described. However, in principle, when m cars are put into service, dividing into m zones will cause the same problem. Can be handled. In the following, description will be made on the assumption that there are two units.
[0020]
FIG. 3 is a flowchart showing a schematic procedure for deriving an equipment plan draft in the present invention. First, in step S101, building specification data is input through the human I / F2 of FIG. Here, the building specification data includes the number of floors of the building, service floor, floor height, population living on each floor, reference floor for each car, and the like. Next, in step S102, the zone division means 1B sets a zone division plan. For example, the following method can be considered as a setting method of the division plan.
[0021]
The resident population is added in order from the lower floor, and a floor that is の of the total resident population, that is, a floor in which the resident population included in each zone is equal is defined as a reference division floor (the top floor of the lower zone). Then, a plan is created in which ± f floors are set as new division floors from the reference floor. For example, when the original reference floor is 11F and f = 2, the following five plans are created.
(Case 1) Lower car: 1F-9F, Upper car: 2F, 10F or more (Case 2) Lower car: 1F-10F, Upper car: 2F, UF or more (Case 3) Lower: 1F-11F, Upper Car: 2F, 12F or more (Plan 4) Lower car: 1F-12F, Upper car: 2F, 13F or more (Plan 5) Lower car: 1F-13F, Upper car: 2F, 14F or more Automatic creation as described above Is not available, a zone division plan may be directly input through the human I / F 2 of FIG.
[0022]
Next, in step S103, the car data setting means 1C sets the car data according to the input building specification and the zone division plan set in step S102.
For this purpose, a method is used in which data relating to standard car specifications is stored in advance in the standard database 1A. For example, if the top floor of the building to be serviced is 11 to 15 floors, the speed is 150 m / min.
180m / min for 16 floors or more and 20 floors or less
If rules are established as in the above, speed specifications can be easily set. If the speed is determined, standard acceleration, jerk, capacity, door width, and the like can be determined correspondingly. Further, when it is not possible to uniquely determine the specification data, a method of determining the specification data interactively through the human I / F 2 may be adopted.
[0023]
When the car / building specification and the service zone are determined by the procedure up to step S103, in step S104, each car circling time calculation means 1D1 calculates the circling time for each car. For example, in the case where calculation is performed for (Section 3) of the division setting plan in the above step S102, the lower car uses 1F-11F, the upper car uses 2F as a reference floor, and calculates the lap time as a single deck elevator that serves 12F or more. Do. Therefore, the calculation procedure here uses the same procedure as the calculation procedure for the conventional single deck. That is, the procedure from steps S902 to S906 in FIG. 4 is adopted.
[0024]
Next, in step S105, the circulation time comparison / calculation means 1D2 calculates a substantial circulation time based on the calculation result in step S104. The important point here is that the calculation procedure in step S104 is the same as the calculation procedure for a single deck, and does not include the interference time between the upper and lower cars. For example, let us consider a case where, in the procedure up to step S104, the lower car orbit time: RTT1 = 120 seconds and the upper car orbit time: RTT2 = 130 seconds. After the lower car finishes service and returns to the main floor, it will not be possible to depart even if the upper car does not restart, even when ready to restart. Therefore, the substantial orbiting time has to be equal to or greater than that of the one with the longer orbiting time of the upper and lower cars.
[0025]
When performing actual control, it is predicted that it is very dangerous that upper and lower cars depart from adjacent floors at the same time, so it is necessary to provide a certain departure interval. When this departure interval is described as Tn, the effective round trip time RTT is calculated by the following equation.
RTT = max {RTT1, RTT2} + Tn
In the above, the value of Tn may be appropriately set from the safety margin design value of the actual product.
As in the above example, when RTT1 = 120 seconds and RTT2 = 130 seconds, for example, if Tn = 10 seconds, the actual rounding time is RTT = 140 seconds. When m cars are used for one shaft, the lap time can be calculated by the following equation.
RTT = max ｛RTT1, RTT2,. . . , RTTm｝ + Tn
[0026]
In step S106, the substantial transport capacity calculating means 1D3 calculates the substantial 5-minute transport capacity per shaft based on the orbital time calculated in step S105. This value can be obtained by the following equation.
Transport capacity per shaft for 5 minutes = 2 x (300 x r) / RTT
When m cars are put into service on one shaft, the following equation is used.
Transport capacity per shaft for 5 minutes = mx (300 x r) / RTT
[0027]
The procedure from steps S103 to S106 is executed for each zone division plan determined in step S102.
[0028]
As described above, when the transport capacity for one shaft for five minutes is calculated for each zone division plan, the optimal plan deriving means 1E compares the transport capacity for one shaft for five minutes for each plan, and has the maximum transport capacity. Select the plan as the optimal plan. In addition, for the plan, the required number of shafts is determined in the same procedure as in step S907 in FIG.
The required number of shafts = 5 minutes traffic demand / 1 shaft 5 minutes transportation capacity, and the zone division plan corresponding to the plan, the car specifications and the required number of shafts are output as a facility plan. Also, in the procedure of step S107, the number of output plans need not necessarily be limited to one. It is also possible to output a certain number of alternatives in the order of the calculated transportation capacity per shaft for 5 minutes as an alternative.
[0029]
The above is the description of the schematic procedure for deriving the equipment plan draft in the embodiment of the present invention. Although the description using the flowchart of FIG. 3 has been described in the form of automatically setting the zone division plan and the car specification, the method of using the elevator facility planning device of the present invention is not limited to this. For example, the car specifications may be directly input, and only the zone division plan may be automatically set. Also, depending on the structural restrictions of the building, the zone division may be determined in advance. In that case, it can simply be used to calculate the actual transport capacity and the required shaft.
