[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator equipment planning apparatus that proposes an appropriate elevator equipment plan by calculating a substantial transportation capacity for an elevator system in which a plurality of cars are put into service in one shaft. .
[0002]
[Prior art]
In general, the selection of elevator equipment (number, speed, capacity) is, for example, “Traffic calculation” as described in “Elevator Planning Guidelines for Architectural Design / Construction” (Japan) Elevator Association (1992). The calculation method called is adopted. This is a method of calculating the number of passengers that can be transported within a unit time (usually 5 minutes) by this elevator when a specific building specification and car specification (speed, capacity, etc.) are given. A procedure is generally adopted in which the calculation result is compared with the population of the building and the number of elevators required is determined.
[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 includes car speed / acceleration, capacity (number of people), door opening / closing time, building floor number, service floor number, floor height, and the like. For example, in the calculation model for an office building, it is assumed that all passengers get on from the reference floor (1F) and do not get on from other floors. This is because the number of elevators capable of transporting a large number of passengers generated at the time of going to work (UP Peak) is calculated.
[0004]
In step S902, a predicted value (predicted stop number) 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 reference floor, r: car capacity (number of people)
[0005]
Next, in step S903, an acceleration time Ta, a local section travel time Trl, and an express section travel time Tre, which are travel times of the car, are calculated based on the above results. A specific calculation procedure is shown below. In the following description, a local section is a section where passengers get off in order, and is a section with a service floor. The other sections are called express sections.
Ta = V / α + t0
Trl = Sl / V + Ta × Fl
Tre = Se / V + Ta × Fe
Here, Sl: Local section distance, Se: Express section distance Fe: Express section stop number (2 when there is an express zone, 1 when there is no express zone)
[0006]
In step S904, a boarding / alighting time Tp, a door opening / closing time Td, and a 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: boarding / exiting time per person [0007]
In steps S905 and S906, the lap time RTT and the 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]
Thus, when the transport capacity HC for 5 minutes is obtained, the required number is determined in step S907. 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 to be 6 (300/50 = 6). Is done. Note that the traffic demand is calculated such that 2000 × 0.15 = 300 people / 5 minutes when, for example, the population of the building is 2000 and 15% of the population is assumed to use the elevator for 5 minutes. The above is the description of the conventional traffic calculation procedure.
[0009]
[Problems to be solved by the invention]
However, the calculation method is based on a single deck (SD) in which one elevator is put into service on one shaft. Recently, a calculation method that expands this calculation procedure to a double deck is also adopted, but when multiple elevators operating independently on one shaft are put into service (hereinafter referred to as a one-shaft multi-car, (Noted as MC). At the present time, MC is still in the research stage, but when this system is put into practical use, traffic calculation and facility 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. For an elevator system in which a plurality of cars are put into service in one shaft, MC traffic calculation and facility planning based thereon are performed in the same manner as in the case of SD. It aims at providing the elevator equipment planning device as a tool which can be carried out.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a block diagram showing an example of the overall configuration of an elevator equipment planning apparatus according to an embodiment of the present invention. In FIG. 1, 1 is a multi-car equipment plan calculation device for deriving equipment plans such as car specifications / numbers suitable for a one-shaft multi-car system, and 2 is for a multi-car equipment plan calculation device 1 This is a human I / F for inputting necessary data and outputting the result. Specifically, the multi-car facility plan calculation apparatus 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 a device such as a display and a keyboard.
[0015]
The multicar construction plan calculation apparatus 1 includes the following means 1A to 1E, and each of the means 1A to 1E is configured by software on the board MPU or a computer. . These are a standard database 1A that stores data related to standard elevator specifications, zone division setting means 1B that automatically sets a plurality of service zone candidate plans that each car gives priority services based on given building specifications, and a standard database Car data setting means 1C for setting specific car specifications from 1A, transport capacity calculation means 1D for calculating the actual transport capacity per shaft based on the set building / car specifications and service zone, and zone division setting This is an optimum plan derivation means 1E for deriving an optimum service zone by comparing the substantial transportation capacity calculated for each service zone candidate proposal set by the means 1B.
[0016]
In addition, the transport capacity calculation means 1D includes each car lap time calculation means 1D1 for calculating the car lap time for each car for each of the building specification / car specification data and the service zone candidate plan set by the zone division setting means 1B. Based on the calculation results of the lap time comparison / calculation means 1D2 and the lap time comparison / calculation means 1D2 for comparing the lap times of the cars, which are the calculation results of the car lap time calculation means 1D1, and calculating the actual lap time. 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 calculation of transport capacity and the concept of priority zones in the present invention will be described with reference to FIG. FIG. 2A is a diagram showing an example in which two cars are put into service on one shaft of 1F-20F. Here, it is assumed that 1F and 2F are the lower car and the upper car main floor, respectively. The reason that the main floor is set to the second floor is that the main floor is the most congested, so that it is considered inefficient to service the two upper and lower cars alternately. This concept is also applied to double decks, and depending on the destination floor, passengers may be guided and requested to board after moving to the second floor by an escalator or the like.
[0018]
In the double deck, two cars are connected, so for example, passengers on “even-numbered floors” are guided and requested to board from the second floor, but in the case of MC, each car operates independently. As shown in FIGS. 2B and 2C, the vehicle is divided into two upper and lower zones (in this example, lower car: 1-11F, upper car: 2F, 12F-20F). The method of getting on board is realistic. If the zone is divided in this way, the transport capacity can be calculated for each upper car and lower car using the conventional SD calculation procedure.
[0019]
However, it should be noted here that the loss time caused by the interference between the upper and lower cars must be taken into consideration. Of course, the top floor of the lower car service zone is considerably below the top floor of the upper car, so the speed of the upper car must be at least equal to or higher than the speed of the lower car. 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. 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, it is equally problematic if the car is divided into m zones. Can handle. In the following, description will be given on the assumption of two units.
[0020]
FIG. 3 is a flowchart showing a schematic procedure for deriving the facility plan in the present invention. First, in step S101, building specification data is input through the human I / F 2 in FIG. Here, the building specification data includes the number of building floors, service floors, floor heights, population living in each floor, reference floors 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 method for setting the division plan.
[0021]
The resident population is added in order from the lower floor, and the floor which is ½ of the total resident population, that is, the floor where the resident population included in each zone is equal is defined as the reference divided floor (the uppermost floor of the lower zone). Then, a plan is created by setting the ± f floor from this reference floor as a new divided floor. For example, when the original reference division floor is 11F and f = 2, the following five plans are created.
(Draft 1) Lower car: 1F-9F, Upper car: 2F, 10F or higher (Draft 2) Lower car: 1F-10F, Upper car: 2F, UF or higher (Draft 3) Lower car: 1F-11F, Upper Car: 2F, 12F or higher (plan 4) Lower cage: 1F-12F, Upper cage: 2F, 13F or higher (plan 5) Lower cage: 1F-13F, Upper cage: 2F, 14F or higher However, the zone division plan may be directly input through the human I / F 2 in FIG.
[0022]
Next, in step S103, the car data setting means 1C sets car data according to the inputted building specifications and the zone division plan set in step S102. For this purpose, a method is adopted in which data relating to standard car specifications is stored in the standard database 1A in advance. For example, if the top floor of the serviced building is 11 to 15 floors, the speed is 150m / min.
180m / min if speed is 16th to 20th floor
If you make rules like this, you can easily set speed specifications. If the speed is determined, standard acceleration, jerk, capacity, door width, and the like can be determined accordingly. Furthermore, when it is not possible to determine uniquely, it is possible to adopt a method of determining specification data in an interactive format through the human I / F2.
[0023]
When the car / building specification and the service zone are determined by the procedure up to step S103, each car lap time calculating means 1D1 calculates the lap time for each car in step S104. For example, when the calculation is performed for (Scheme 3) of the division setting plan in step S102, the lap time is calculated as a single deck elevator that services 12F or more with 1F-11F for the lower car and 2F for the upper car as a reference floor. Do. Therefore, the calculation procedure here is the same 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 lap time comparison / calculation means 1D2 calculates a substantial lap time based on the calculation result of step S104. The important point here is that the calculation procedure of step S104 is equivalent to the calculation procedure for the single deck, and the interference time of the upper and lower cars is not included. For example, let us consider a case where, in the procedure up to step S104, the lower car turn time: RTT1 = 120 seconds and the upper car turn time: RTT2 = 130 seconds. After the lower car has finished service and returned to the main floor, even if it is ready to start again, it cannot leave unless the upper car starts again. Therefore, the substantial lap time must be equal to or greater than that of the upper and lower cages with a larger lap time.
[0025]
When actual control is performed, it is predicted that it is very dangerous for the upper and lower cars to depart from adjacent floors at the same time, and therefore it is necessary to provide a certain departure interval. When this departure interval is described as Tn, the substantial lap time RTT is calculated by the following equation.
RTT = max {RTT1, RTT2} + Tn
The value of Tn may be set as appropriate based on the safety margin design value of the actual product.
As in the above example, when RTT1 = 120 seconds and RTT2 = 130 seconds, for example, assuming that Tn = 10 seconds, the actual circulation time is RTT = 140 seconds. When m cars are put into service on one shaft, the lap time can be obtained by the following equation.
RTT = max {RTT1, RTT2,. . . , RTTm} + Tn
[0026]
In step S106, the substantial transportation capacity calculating means 1D3 calculates the substantial transportation capacity for 5 minutes per one shaft based on the lap time calculated in step S105. This value can be obtained by the following equation.
1 shaft 5 minutes transport capacity = 2 × (300 × r) / RTT
When m cars are put into service on one shaft, the following formula is obtained.
1 shaft 5 minutes transport capacity = m x (300 x r) / RTT
[0027]
The procedure from step S103 to step S106 is executed for each zone division plan determined in step S102.
[0028]
As described above, when the transport capacity for one shaft for 5 minutes is calculated for each zone division plan, the optimum plan proposal deriving means 1E compares the transport capacity for one shaft for 5 minutes for each plan and has the maximum transport capacity. Select the plan as the best plan. Further, based on the plan, the required number of shafts is determined according to the following equation based on the calculated 5-minute transportation capacity and the expected building traffic demand in the same procedure as step S907 in FIG.
Necessary number of shafts = 5 minutes traffic demand / 1-shaft 5 minutes transportation capacity and the zone division plan corresponding to the plan and the car specification / the number of necessary shafts are output as the equipment plan Further, it is not always necessary to limit the number of plans to be output in the procedure of step S107. A certain number of plans may be output as alternatives in descending order of the calculated 1-shaft 5-minute transportation capacity.
[0029]
The above is the explanation of the outline procedure for deriving the facility plan in the embodiment of the present invention. In the description using the flowchart of FIG. 3, the zone division plan and the car specification are described in the form of automatic setting. However, the method of using the elevator facility planning apparatus of the present invention is not limited to this. For example, the car specification may be directly input and only the zone division plan may be automatically set. Depending on the structural restrictions of the building, zone division may be determined in advance. In that case, it can also be used to calculate the actual transport capacity and the required shaft.
