2. Description of the Related Art FIG. 9 shows an entire conventional equipment capacity determination support device for elevators shown on pages 31 to 47 of "1992 Elevator Planning Guide for Building Design and Construction" (published by the Japan Elevator Association). It is a block diagram which shows a structure. In the figure, 1 is a specification input unit for inputting building specifications, car specifications, and traffic demand. 2 is this specification input unit 1
11 is a service performance index calculation unit that calculates a service performance index according to the input specifications, 11 is a lap time / maximum transport capacity calculation unit that calculates the car lap time and maximum transport capacity, and 12 is the number and average of cars. This is a calculation unit for the number of cars and the average operation interval for calculating the operation interval. A service performance index output unit 3 outputs the number of cars calculated by the service performance index calculation unit 2 and the average operation interval as a service performance index of the elevator.

Next, the operation will be described. The traffic calculation described in the above document aims to find the necessary and sufficient number of cars to meet the traffic demand during peak hours. That is, the building specification, the car specification, and the traffic demand input from the specification input unit 1 are given to the lap time / maximum transportation capacity calculation unit 11 of the service performance index calculation unit 2, and the car departs from the departure floor and starts again. The lap time until returning to the floor is obtained, and the maximum transport capacity of the car is calculated from the lap time obtained and the number of passengers in the car. Then, the required number of cars is determined from the given traffic demand and the maximum transportation capacity of the car. The number of cars and the average operation interval thus obtained are output from the service performance index output unit 3. In addition, as the service performance index, the waiting time of the elevator user,
For convenience, the average elevator interval is used.

As a conventional elevator installation planning work support device, other than this, for example, Japanese Patent Laid-Open No. 3-288 is known.
There is also one as shown in Japanese Patent No. 777.

Furthermore, the round-trip time and the maximum transport capacity of the elevator are required from the given building specifications and car specifications, and the number of cars required to transport a given traffic demand can be uniquely calculated. There was also a problem that it was not possible to know the elevator performance in each case.

Further, according to the technique disclosed in Japanese Patent Laid-Open No. 3-288777, target inputs such as facility cost, transportation capacity and service performance, the personnel composition in a building, the correlation between floors, the utilization of tenants, etc. Because the simulation is repeatedly executed until the target is achieved based on the condition input of
Not only does the calculation take a long time, but it is necessary to enter parameters that are usually unknown at the stage of elevator equipment planning, such as personnel composition in the building, correlation between floors and tenant utilization. There was a problem that it would not happen.

The configuration of the equipment quantity determination support device for an elevator according to the first embodiment of the present invention shown in FIG. 2 and FIG. 2 is different from the configuration of the equipment quantity determination support device for a conventional elevator shown in FIG. There are differences. That is, in the first embodiment, the specification input unit 1 gives the number of cars in addition to the building specification, the elevator specification, and the traffic demand. In addition, the service performance index calculation unit 2 is provided with a harmony state calculation unit 13, and instead of the average operation interval as the service performance index, the number of people left unloaded on the main floor, the car departure interval, and the car presence rate in the harmony state. It is adopted.
The elevator equipment amount determination support device according to the first embodiment is different from the conventional device in these points.

From the specification input unit 1, an elevator form indicating whether one or a plurality of cars are installed on one or a circulation type shaft, a service system indicating how to arrange a stop floor, and a floor height Building specifications such as Sa and capacity,
Elevator specifications such as maximum number of passengers, door opening / closing time, speed, etc., traffic demand including arrival intervals, arrival distribution and amount of passengers occurring at the hall, and the number of cars installed on the shaft are given. The service performance index calculation unit 2 obtains the service performance index of the elevator in the harmony state according to the specifications given by the specification input unit 1, and the service performance index output unit 3
Then, in the harmony state obtained by the service performance index calculation unit 2, the service performance indexes such as the number of unloaded items on the main floor, the car departure interval, and the car existence ratio are output to the equipment planner and the customer in a graph or the like.

In the service performance index calculation unit 2, the harmony state calculation unit 13 is used to obtain the harmony state according to the building specifications, elevator specifications, number of cars, and traffic demand given from the specification input unit 1. Calculate. As a result, if a harmonic state exists, the harmonic state service performance index calculation unit 14 calculates the service performance index of the elevator in the harmonic state. The service performance indexes calculated at that time include the number of people left unloaded on the main floor in a harmony state, car departure intervals, and car existence rates.

Here, the harmony state in a situation where passengers concentrate on a specific floor called the main floor, such as when commuting to work, is obtained by the harmony state calculation unit 13 in the following procedure. In addition, the harmony state at the time of going to work means that the car arrives on the main floor with the operation cycle of the elevator car and the arrival cycle of passengers arriving at the hall in harmony, and the same number of passengers according to the arrival distribution of passengers An average driving state in which the situation of riding in one car is repeatedly realized.

First, the waiting number setting section 21 sets an initial value of the number of passengers waiting before the car arrives. Next, in the car stop time calculation unit 22, the sum of the set number of waiting persons and the number of arrivals of the passengers who have arrived until the arrival of the passengers ends (that is, the arrival of the passengers is interrupted) and the arrival of the passengers are interrupted. Based on the elapsed time up to, determine the car stop time on the main floor and the number of passengers from the elevator specifications. The details of an example of how to obtain the value will be described later with reference to FIG.

In the car stay time calculation unit 23, the car departs from the main floor and returns to the main floor again based on the number of passengers and the number of stop floors of the building obtained by the car stop time calculation unit 22. The number of times to stop is calculated, and the car stay time (UFT) is calculated in consideration of the car speed and the door opening / closing time.

The orbit time calculation unit 24 calculates the car stop time (MFT) calculated by the car stop time calculation unit 22 and the car stay time (UFT) calculated by the car stay time calculation unit 23.
The round trip time (RTT) is calculated using the following equation (1). RTT = MFT + UFT (1)

Next, in the car departure interval calculation unit 25,
The round trip time (RTT) calculated by the round trip time calculator 24
And the number of cars (cage
From s), the car departure interval (DIT) is calculated by the following equation (2). DIT = RTT / cases (2)

Further, the car departure interval (DIT) calculated by the departure interval calculation unit 25 and the car stop time calculation unit 2
From the car stop time (MFT) obtained in step 2, the car presence rate (MFP) can be defined by the following equation (3). MFP = MFT / DIT (3)

Next, in the waiting person calculation unit 26, the car departure interval (DI calculated by the car departure interval calculation unit 25 is calculated.
T), the car stop time (MFT) on the main floor obtained by the car stop time calculation unit 22, and the door _close time (t _close ) and door open time (t _open ) given from the specification input unit 1. The number of passengers waiting for the next car (a ₀ ^{nex t} ) is calculated from the passenger arrival interval (1 / λ) and the number of passengers arriving once (g) using the following equation (4). a ₀ ^next = (t _close + DIT−MFT + t _open ) × λ × g (4)

Thereafter, in the waiting person determination unit 27, the difference between the waiting number set by the waiting number setting unit 21 and the waiting number for the next car obtained by the waiting number calculation unit 26 is calculated to determine the convergence. I do. If there is a large difference between the number of people waiting and the number of people waiting for the next car,
Recalculation is performed after updating the waiting number set by the waiting number setting unit 21. If the difference between the two is sufficiently small, the same number of passengers can ride on the car each time, and the cars can operate at equal intervals in the same lap time. That is, the harmony state, which is the average operation state of the elevator with respect to the given building specifications, elevator specifications, number of cars, and traffic demand, is required.

Next, the operation of the car stop time calculating section 22 will be described in detail with reference to FIG. The processing unit 33 obtains the expected value of the number of passengers (arrival number) who arrive at the sum of the door-opening time and the set waiting time (boarding time) from the arrival intervals of passengers and the number of passengers arriving once. And the determination unit 3
It is determined whether or not the sum of the number of passengers arriving in 4 and the number of passengers already on board exceeds a predetermined capacity. Processing department 3 if full
When 0, the door is closed. If the passengers are not full, the determination unit 35 determines whether or not the passengers have finished riding, that is, whether or not all passengers who have arrived due to an interruption in passenger arrival have finished riding. This determination is obtained by obtaining the boarding time in which the waiting passengers set in the processing section 31 board, and the expected value of the number of arriving passengers arriving at the boarding time in the processing section 33. The determination unit 35 determines whether the expected number of arrivals exceeds the number of arrivals at one arrival. In addition, with the arrival number of people in one arrival,
It is a value indicating how many passengers arrive in a lump.

The determination as to whether or not the passenger has boarded is specifically performed as follows. Now, "Number of people arriving at one arrival" is 3
Let's be a person. When the expected value of the number of passengers arriving at the n-th time in the processing unit 33 is 4.5 and the determination unit 34 determines that the number of passengers does not exceed the total number of passengers, the determination unit 35 gets on the vehicle. A determination of termination is made. In this case, the expected number of arriving passengers, which is 4.5, exceeds the number of arriving passengers in one arrival, which is 3, so it is determined that the passengers continue to board. Next, when the expected value of the (n + 1) th number of arrivals in the processing unit 33 becomes 2.3, and the determination unit 34 determines that the number of passengers has not exceeded the capacity, the determination unit 34 At 35, it is determined whether or not the passenger has finished boarding. In this case, since the expected number of arriving passengers, 2.3, does not exceed the "three arriving passengers per arrival", it is determined that the boarding has ended.

If the boarding has not ended, the processing section 32 again obtains the boarding time of the newly arrived passenger. When it is determined that the boarding has ended, the processing unit 36 obtains the time obtained by adding the door closing determination time, and further, the processing unit 37 obtains the expected value of the number of arrivals at that time. Here, the determination unit 38 determines whether or not the sum of the number of newly arrived passengers and the number of passengers who have already boarded exceeds a predetermined capacity. As a result, if it is full, the processing unit 30 performs the door closing process. If the passengers are not full, the determination unit 39 determines the end of boarding as in the case described above, and if the boarding has not ended, the processing unit 32 again obtains the boarding time of the newly arrived passenger. When it is determined that the boarding has ended, the processing unit 30 performs the door closing process. In this way, the number of passengers and the car stop time on the main floor for a given number of waiters are calculated based on the sum of the number of passengers arriving before the passengers are cut off and the elapsed time until then.

As described above, the elevator equipment amount determination support apparatus according to the first embodiment is in an average operation state of elevators according to the input building specifications, elevator specifications, number of cars, and traffic demand specifications. It is possible to calculate a service performance index in a certain harmony state. For example, when the traffic demand is 80 persons / 5 minutes and the number of cars is three, the number of unloaded elevators in a harmony state, the car departure interval, and the car existence rate are calculated. By fixing the traffic demand to 80 people / 5 minutes and changing the number of cars from 3 to 9, etc., the service performance index for each number of cars can be obtained. With this car number as a parameter,
By displaying the service performance indexes such as the number of unloaded items, the car departure interval, and the car existence rate in a graph, it is possible to present the fluctuation of the elevator service performance due to the fluctuation of the number of cars to the equipment planner and the customer.

As described above, according to the first embodiment, the inputted building specifications, elevator specifications, the number of cars,
And since the elevator service performance index according to the traffic demand is output, by changing each of those specifications, it is possible to present a number of equipment plan proposals to equipment planners and customers, as input parameters, As long as there are building specifications, elevator specifications, number of cars, and traffic demand, not only can the burden on the equipment planner be reduced, but also the elevator operation upon arrival of passengers in the harmony state obtained by the harmony state calculation unit. There is an effect that it is possible to calculate the service performance index of the elevator in consideration of the influence of, and further, as the service performance index, it is possible to use the number of people left unloaded in the harmony state, the car departure interval, the car existence rate, etc. The quantitative service status of the elevator based on the number of people left over, such as car departure interval and car existence rate. A group management system that can evaluate the qualitative service status of elevator passengers and uses the car presence rate on the main floor as a group management parameter uses the same index at the equipment planning stage and after the elevator is in operation. The effect is that the performance of the existing elevator can be evaluated.

Embodiment 2 In the first embodiment described above, the case where the service performance index in the harmony state is obtained and output is described. However, the harmony state may not be obtained because the car departure interval is shorter than the car stop time.
In the second embodiment, a quasi-harmonic state is considered as an average operation state of the elevators similar to the harmonious state in such a case, and an elevator service performance index in the quasi-harmonic state is obtained and output. Is.

FIG. 4 shows such a second embodiment of the present invention.
FIG. 3 is a block diagram showing an overall configuration of an elevator equipment amount determination support device according to the present invention. In the figure, 1 is a specification input section, 2
Is a service performance index calculation unit, 3 is a service performance index output unit, 13 is a harmony state calculation unit, and 14 is a harmony state service performance index calculation unit.

Is a quasi-harmonious state service performance index calculation unit that calculates a service performance index in the quasi-harmonious state when the quasi-harmonious state determining unit 17 confirms the existence of the quasi-harmonious state. In addition, the service performance index calculation unit 2 includes the harmony state calculation unit 13
In addition to the harmonic state service performance index calculation unit 14, the harmonic state determination unit 15, the quasi-harmonious state calculation unit 16, the quasi-harmonious state determination unit 17, and the quasi-harmonious state service performance index calculation unit 18 are provided. It is different from that of Form 1.

FIG. 5 is a block diagram showing the internal structure of the quasi-harmonic state calculating section 16. In the figure, reference numeral 41 is a passenger number setting unit for setting the number of passengers. 42
Calculate the car stay time, which is the time required for the car that left the main floor to return to the main floor again, based on the number of passengers set by the passenger number setting unit 41 and the number of stop floors according to the building specifications. It is a car stay time calculation unit. A car departure interval calculation unit 43 calculates a car departure interval from the car stay time obtained by the car stay time calculation unit 42 and the given number of cars. Reference numeral 44 denotes a car stop time calculation unit that calculates the car stop time on the main floor from the car departure interval and the door closing time obtained by the car departure interval calculation unit 43. 45
Is a passenger number calculation unit that calculates the number of passengers from the car departure interval and passenger arrival intervals. Reference numeral 46 is a passenger count determination unit that determines convergence based on the passenger count set by the passenger count setting unit 41 and the passenger count calculated by the passenger count calculator 45.

Next, the operation will be described. First, in the harmony state calculation unit 13 of FIG. 4, a harmony state corresponding to each specification of the building specifications, elevator specifications, number of cars, and traffic demand input by the specification input unit 1 is obtained, and the harmony state determination unit 1
At 5, it is determined whether or not there is a harmony state. As a result, if a harmony state exists, the harmony state service performance index calculation unit 14 obtains the service performance index in the harmony state. The calculation of the service performance index in this harmony state is performed in exactly the same manner as in the first embodiment. The service performance index output unit 3 is the harmony state service performance index calculation unit 1
The number of unloaded items, car departure intervals, car existence ratios, etc., as service performance indicators in the harmonious state, obtained in step 4, are presented to equipment planners and customers in a graph.

On the other hand, as a result of the judgment by the harmonic state judging section 15, if the harmonic state does not exist, the quasi-harmonic state calculating section 16 calculates the quasi-harmonic state. That is, the quasi-harmonic state calculation unit 16 obtains the quasi-harmonious state according to each of the building specifications, elevator specifications, number of cars, and traffic demand specifications input by the specification input unit 1, and the quasi-harmonious state determination unit 17 determines the quasi-harmonic state. The presence or absence of a harmony state is determined. If a quasi-harmonic state exists as a result of the determination, the quasi-harmonious state service performance index calculation unit 18 obtains a service performance index in the quasi-harmonic state. The service performance index output unit 3 calculates the number of unloaded items as the service performance index in the quasi-harmonic state, the car departure interval, the car presence rate on the main floor, and the like, which are obtained by the quasi-harmonious state service performance index calculation unit 18, Present to equipment planners and customers using graphs.

Here, the quasi-harmonic state in a situation where passengers concentrate on a specific floor called the main floor, such as when commuting to work, is obtained by the quasi-harmonic state calculation unit 16 in the following procedure. In addition, the semi-harmonious state at the time of going to work means that if another car arrives on the main floor while a passenger is on one car on the main floor, the process of getting on the previous car is interrupted. A situation in which passengers get into the next car repeatedly and is in the same state as the harmony state when going to work.

Since one car is always present on the main floor in the quasi-harmonic state, the number of people waiting is zero. First, the passenger number setting unit 41 shown in FIG. 5 sets an initial value of the number of passengers. Next, the car stay time calculation unit 42 obtains the number of stops in one lap from the set number of passengers and the number of floors stopped, and the car departs from the main floor based on elevator specifications such as car speed. Find the time required to return to the main floor again or the stay time. Next, in the car departure interval calculation unit 43, the obtained car stay time (UF
From T) and the given number of cars (cases), the car departure interval (DIT) is calculated using the following equation (5). DIT = UFT / (cases-1) ... (5)

Next, in the car stop time calculation unit 44,
Calculate the car stop time on the main floor from the sum of the car departure intervals and door closing times. Next, in the passenger number calculation unit 45, the car departure interval (DIT) and the passenger arrival interval (1 / λ)
Then, from the number of passengers (g) who have arrived at one time, the number of passengers (r ^next ) is calculated using the following equation (6). r ^next = DIT x λ x g (6)

Recalculate after updating the set number of passengers. If the difference between the two is sufficiently small, the same number of passengers can ride on the car each time, and the cars can operate at equal intervals in the same lap time. In other words, the quasi-harmonious state, which is the average operating state of the elevator that is realized for the given traffic demand and the number of cars, building specifications, and elevator specifications, is required.

As described above, the elevator equipment amount determination support device according to the second embodiment can obtain the harmonic state of the elevator according to the input building specifications, elevator specifications, number of cars, and traffic demand specifications. Even if it is not possible, the quasi-harmonic state corresponding to each of the specifications can be obtained and the service performance index in the quasi-harmonious state can be calculated. Similar to the first embodiment, for example, the soaring demand is 8

Embodiment 3 In the first embodiment, the car stop time calculation unit 22 definitely determines the end of boarding based on the sum of the number of passengers and the elapsed time until the arrival of passengers is interrupted, and the car stops on the main floor. Although the case where the time and the number of passengers in the car are obtained has been described, the passengers can be terminated based on the probability that the passengers will arrive at the i-th time and the expected value of the number of passengers and the expected elapsed time up to the i-th time. Alternatively, the car stop time and the number of passengers in the car may be determined deterministically. FIG. 6 is a harmonic state calculation unit 13 or a quasi-harmonic state calculation unit 16 of such an elevator equipment quantity determination support apparatus according to Embodiment 3 of the present invention.
It is explanatory drawing which shows the processing procedure in the car stop time calculation part 22 in. The operation will be described below with reference to FIG.

As shown in FIG. 6, after the previous car starts closing the door, the passengers a ₀ who arrive at the time when the next car arrives and the door is completely opened are waiting passengers. If no other passenger arrives during the time t ₀ when that a ₀ passenger gets in the next car, the car will leave with 0 consecutive arrivals and the number of arrivals A ₀ will be A ₀ = a ₀ people, the elapsed time T ₀ is T ₀ = t ₀ seconds. On the other hand, if another passenger arrives during the time t ₀ when a ₀ passengers board the vehicle, the number of arrivals continues for the first time. Arrived the first time a ₁
If no other passenger arrives during the time t ₁ for a passenger to board, the car will be closed with one consecutive arrival, and the number of arrivals A ₁ will be A ₁ = a ₀ + a ₁ Person, elapsed time T ₁
Is T ₁ = t ₀ + t ₁ seconds. Therefore, if the other passengers during the time t _i that a _i passengers arriving at the i-th to ride does not arrive even one person, the car with the arrival continues the number of times i is starting with the door closing, the number of people A _i Is given by the following equation (7), and the elapsed time T _i is given by the following equation (8).

[0057]

[Equation 1]

Therefore, the number of arrivals (A ^e ) from all these combinations is the sum of the number of arrivals up to the i-th time (A _i ) where P _i is the probability that the arrival of passengers at the i-th time is completed.
Can be obtained as an expected value from the following equation (9).

[0059]

[Equation 2]

However, in reality, since only the maximum number of passengers (c) of the car as a capacity can be boarded, the number of passengers (G ^e ) on the car can be obtained from the following equation (10).

[0061]

(Equation 3)

In addition, the car stop time (MFT
^e ) is the door opening time (t _open ), the probability P _i that the passengers arrive at the i th time, the elapsed time (T _i ) up to the i th time with the maximum number of passengers as the upper limit, and the door closing time ( t _close ), it can be obtained by the following equation (11).

[0063]

(Equation 4)

When the number of arriving passengers (A _i ) exceeds the maximum number of passengers (c), the remaining load (L _i ) shown in the following equation (12)
Occurs.

[0065]

(Equation 5)

From this fact, the number of unshipped persons (L ^e ) is i
Using the probability P _i that the arrival ends at the next time, the following (13)
It can be calculated from the formula.

[0067]

(Equation 6)

Here, if the car departure interval is DIT ^e when the car stop time is MFT ^e , the time when the car is not on the boarding floor, that is, the car absence time (RT ^e ) is as follows.
It is calculated by the equation 4). RT ^e = DIT ^e −MFT ^e = (1−MFP ^e ) × DIT ^e (14)

[0069] In addition, the arrival number of people at the arrival end of the probability P _i is A _i
When there is a leftover number of people, car departure interval, car absence time, car outage time, car existence rate, we obtain the leftover population distribution, car departure interval distribution, car absence time distribution, car outage time distribution, car existence distribution, respectively. be able to.
Each of these distributions is an index representing those values and their occurrence probabilities.

When the number of arrivals is A _i with the arrival completion probability P _i , the number of people left unloaded, the car departure interval, the car absence time,
From the probabilities that the car stop time exceeds a predetermined fixed value, it is possible to obtain the multi-load remaining probability, the long car departure interval probability, the long car absence time probability, and the long car stop time probability, respectively. Further, the low car existence rate probability can be obtained from the probability that the car existence rate does not reach a predetermined value when the number of arrivals is A _i with the arrival completion probability P _i .

In this way, in the service performance index calculation unit 2, an elevator form indicating whether one or a plurality of cars are installed on one or a circulation type shaft given from the specification input unit 1 Building specifications such as service method and floor height indicating how to arrange floors, elevator specifications such as capacity and speed, traffic demand including arrival intervals, arrival distribution and amount of passengers occurring at the hall, Based on the number of cars installed on the shaft, the number of people left unbalanced in a harmonious state, the distribution of the number of people left unloaded, the probability of leaving many items, the car departure interval, the car departure interval distribution, the long car departure interval probability, the car absence time, the car absence time distribution, Long car absence time probability, car down time, car down time distribution, long car down time probability,
Service performance indicators such as car abundance, car abundance distribution, and low car abundance probability are calculated. Service performance index output unit 3
Outputs the service performance indexes calculated in detail by the service performance index calculation unit 2 to a facility planner or a customer in a graph or the like.

For example, for a building or car with a certain specification,
When 180 passengers occur on the main floor for 5 minutes for 6 cars, the expected number of unloaded passengers is 1.94.
Expected value for people and car departure interval is 28.68 seconds, expected value for car absence time is 9.64 seconds, expected value for car stop time is 1
9.04 seconds, expected car presence rate is 0.66, the minimum number of unloaded people is 0, the maximum is 6.15 from the unloaded population distribution, and the minimum value of car departure interval is 23 from the car departure interval distribution. .76 seconds, maximum value is 29.74 seconds, minimum value of car absence time is 8.14 seconds, maximum value is 9.88 seconds from car absence time distribution, minimum value of car stop time is 15 from car stop time distribution Each service performance index was calculated as 0.62 seconds, the maximum value was 19.84 seconds, and the probability of being left over and over was 0.81.
