Description

The present invention relates to an elevator operating state evaluation device and evaluation method for evaluating the operating state of an elevator.

Elevators are vertical transportation systems within buildings, and support the smooth movement of users within buildings. Inside a building, elevators may operate individually or in combination. In particular, in cases where multiple elevators are in operation, an elevator group management system that centrally controls multiple elevators as a "group" realizes efficient operation while taking into account the waiting time of users. . In recent years, elevator group management systems have been performing control to predict the trajectory of cars and further reduce waiting times. However, depending on the operating state of the elevator and the usage state of the user, the operating performance of the elevator may deteriorate.

On the other hand, it is important to quantify and quantify the operation status of elevators and the usage status of elevators by users. A technique for calculating the equipment load factor using the above method is disclosed in, for example, Patent Document 1.

In the conventional technology described in Patent Document 1, the equipment load factor, which is calculated based on the number of people getting on and off each floor and the transport capacity calculated in advance, is calculated by converting the operation status of the elevator into a variable in the control device of the target elevator. This is what I did. That is, the equipment load factor in the prior art is used to determine elevator control parameters, and is not used to objectively evaluate the quality of the elevator's operating condition. For example, it does not evaluate the operating status of elevators in comparison with elevators in other buildings. For this reason, there is a problem in that it is difficult to evaluate the operation status of elevators using conventional techniques.

Embodiments according to the present invention will be described below based on the drawings.

First, the main points of the concept of the embodiment regarding the elevator operation status evaluation device according to the present invention will be explained.

First, the purpose is to objectively evaluate the quality of the operating condition of the elevator, and evaluate the operating condition of the target elevator operating in the building by comparing it with other elevators. There is a particular thing. For example, specific comparative evaluations include comparing the target elevator with elevators in other buildings, comparing elevators with elevators in different elevator banks in the same building (e.g., high-rise banks and low-rise banks), Comparisons can be made between different elevators within the same building, and comparisons can be made between the same elevator but under different operating conditions. Building owners and building managers want to know how the operating conditions of their own building's elevators are, especially in comparison with other buildings and bank elevators in the same building. becomes important.

By comparing and evaluating the operation status of elevators with different equipment specifications and operating conditions using the same standards and scale, we can evaluate, for example, the speed and capacity of the elevator, the number of floors served in the building, the distance of the journey, and even more. For elevators with various equipment specifications and operating conditions, such as usage conditions, it is important to have a method for evaluating elevators using appropriate standards.

The idea of solving this problem is to introduce an evaluation value that is "normalized (standardized)" as an indicator of the operating status of the elevator using a standard value according to the equipment specifications and operating conditions, and use this index to improve the performance of the elevator in question. The purpose of this is to evaluate the operating status by comparing it with the operating status of other elevators. Specifically, we perform traffic calculations that mathematically model the operating status of elevators based on equipment specifications and operating conditions, calculate features of the operating status as reference values, and use them as indicators of elevator operating status. , the evaluation value is obtained by normalizing it with the reference value obtained from the traffic calculation.

This solution makes it possible to objectively evaluate the operational status of elevators, even if the equipment specifications and operating conditions are different.

Hereinafter, one embodiment of an elevator system including an elevator operation state evaluation device according to the present invention will be described.

FIG. 1 is an overall configuration diagram showing an embodiment of an elevator system including an elevator operation status evaluation device according to the present invention. The elevator operation status evaluation device is a device that collects operation data regarding the operation status from each elevator in a building, and uses the collected operation data to quantify and evaluate the operation status of the target elevator. Here, when quantifying the operation status of an elevator, an indicator of the elevator operation status (operation status index) is normalized with a reference value (operation status reference value) according to the equipment specifications and operating conditions, and the evaluation value (operation status index) is condition evaluation value).

In FIG. 1, an elevator operation status evaluation device 1 is a mechanism for evaluating the operation status of an elevator, which is the key point of the present invention, and evaluates the operation status based on operation data of elevators in a building. At this time, the elevator operation status evaluation device 1 is connected to the operation data remote collection device 9 and the information terminal 22, respectively, by wire or wirelessly. Of the target buildings 2 and 3, two groups of elevator banks including bank 4 and bank 5 are arranged in building 2. The bank 4 is composed of an elevator group 6 including a plurality of elevators, and the bank 5 is composed of an elevator group 7 including a plurality of elevators. On the other hand, in the building 3, an elevator group 8 including a plurality of elevators is arranged. Here, an elevator bank refers to a group of multiple elevators having the same platform, and examples of elevator banks include high-rise banks and low-rise banks. In this example, a group of elevators (a group of elevators) is used as an example, but the same applies to the case of only one elevator.

The operation data remote collection device 9 remotely collects operation data from each elevator group 6, 7, 8 through a communication network. The collected operation data is stored as a database in the operation data remote collection device 9. This operation data remote collection device 9 stores operation data of elevators operating in a large number of buildings.

The elevator operation status evaluation device 1 is a device that captures operation data online or offline from the operation data remote collection device 9, and quantitatively evaluates the operation status of the target elevator based on the captured operation data. , for example, is composed of a computer (not shown) including a processor, a main storage device, an auxiliary storage device, an input device, an output device, and a communication device.

The processor is configured using, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit).

The main storage device is a device that stores computer programs and data, and includes, for example, ROM (Read Only Memory), RAM (Random Access Memory), and nonvolatile semiconductor memory.

Examples of auxiliary storage devices include hard disk drives, SSDs (Solid State Drives), optical storage media (i.e., CDs (Compact Discs), DVDs (Digital Versatile Discs), etc.), storage systems, and IC cards (Integrated Circuit Cards). , a reading/writing device for recording media such as an SD (Secure Digital) memory card, and a storage area of a cloud server. Computer programs and data stored in the auxiliary storage device are read into the main storage device at any time.

Input devices include, for example, a keyboard, a mouse, a touch panel, a card reader, and a voice input device. The output device is a user interface that provides the user with various information such as processing progress and processing results. The output device is, for example, a display device (i.e., a liquid crystal monitor, an LCD (Liquid Crystal Display), a graphic card, etc.), an audio output device (i.e., a speaker, etc.), a printing device, or the like.

The communication device is a wired or wireless communication interface that realizes communication with other devices via communication means such as a LAN or the Internet. The communication device is, for example, a NIC (Network Interface Card), a wireless communication module, a USB (Universal Serial Bus) module, or a serial communication module.

Specifically, the elevator operation status evaluation device 1 includes an operation data collection unit 10, an operation status index calculation unit 11, a building specification/application database 12, an equipment specification database 13, an operation condition detection unit 14, an operation condition setting unit 15, It includes a driving condition reference value calculating section 16, a driving condition evaluation value calculating section 17, a driving condition evaluation value DB (database) 18, an evaluation standard value calculating section 19, a driving condition evaluating section 20, and a result outputting section 21.

Operation data collection section 10, operation condition index calculation section 11, operation condition detection section 14, operation condition setting section 15, operation condition reference value calculation section 16, operation condition evaluation value calculation section 17, evaluation reference value calculation section 19, operation condition The evaluation unit 20 and the result output unit 21 are configured to run programs stored in the auxiliary storage device, such as an operation data collection program, an operation condition index calculation program, an operation condition detection program, an operation condition setting program, an operation condition reference value calculation program, The functions are realized by the CPU reading out the driving condition evaluation value calculation program, the evaluation reference value calculation program, the driving condition evaluation program, and the result output program from the auxiliary storage device and developing them on the RAM.

The operation data collection unit 10 receives operation data of a plurality of elevators from the operation data remote collection device 9, such as elevators to be evaluated (elevators to be evaluated) and elevators used for comparison with other buildings (elevators to be compared). collect. The operation data includes data indicating the position of the car, data indicating the weight of the car (load acting on the car), data indicating the destination floor, data indicating the open/closed state of the car door, etc. It is managed in relation to time (time). The operation state index calculation unit 11 calculates the value of the operation state index as an index for the operation state of the elevator based on the operation data collected by the operation data collection unit 10. The value of this operation status index becomes a base value for quantitatively evaluating the operation status of the elevator. Operation status indicators include, for example, the number of people using the elevator, the time required for the elevator to make one round up and down the hoistway (average one round time), and the average platform call that indicates the waiting time for the elevator at the platform. There are durations, etc. The operation status index includes an index for operation performance, such as the waiting time for an elevator at a boarding point, and an index for factors that cause deterioration of operation performance, such as the number of people using an elevator. Note that a specific example of the operation state index will be described later with reference to FIG. 10.

The building specification/use database 12 stores building specification data indicating the building specifications of the building and building use data indicating the use of the building, which are data used as input values for calculating the reference value of elevator operation status. be done. The equipment specification database 13 stores equipment specification data, which is data that is an input value for calculating the elevator operating state reference value and indicates the equipment specifications of the elevator. Since these data are related to the specifications of buildings and equipment, they are basically constants (fixed values that do not change over the years), and are collected from, for example, elevator control equipment via the operation data remote collection device 9. can be collected.

The operation condition detection unit 14 takes in elevator operation data from the operation data remote collection device 9, and detects the actual operation conditions of each elevator to be evaluated at the site based on the elevator operation data. This operating condition is, for example, data indicating a stop floor (service floor), a reference floor (lobby floor), etc., and serves as an input value for calculating the operating state reference value of the elevator in the operating state reference value calculation unit 16. . These operating conditions are different from the equipment specifications and may change depending on the operation of the elevator. Therefore, the operating condition detection unit 14 detects the operating conditions at that time from the operation data obtained from the operation data remote collection device 9. In addition, there are cases in which it is desired to estimate how the operating condition of the elevator will be improved if the settings of the operating conditions are changed. In that case, the operating condition setting unit 15 can set a case in which the operating condition setting is temporarily changed. This is, for example, a function used for preliminary evaluation in the event that the current operational performance is not good and could be improved through operation.

The operating condition standard value calculation unit 16 calculates standard values based on the data (building specification data and building usage data) stored in the building specification/application database 12 and the equipment specification data stored in the equipment specification database 13. do. This reference value becomes a reference value used by the operation state evaluation value calculation unit 17 in "normalization" when calculating the operation state evaluation value. By normalizing the operation status index using this reference value, the operation status evaluation value calculation unit 17 can standardize differences in equipment specifications and operating conditions of different elevators, and absorb the differences. Specifically, as this reference value, a feature amount of the operating state obtained by traffic calculation that models the operating state of the elevator is used. Here, traffic calculation is a calculation model of elevator operation status used in elevator traffic planning, and is described, for example, on pages 53 to 74 of "Elevator and Escalator Planning for Architectural and Facility Engineers" (published by Gijutsu Shoin). ing. Indices of the reference value calculated based on traffic calculations include transport capacity (5-minute transport capacity), one round time, average driving interval, number of stops per round, and stopping time for one stop. Note that a specific example of the reference value will be described later with reference to FIG.

This reference value can be regarded as a theoretical performance value of the operating state of the elevator, which is calculated based on traffic calculations from data such as elevator equipment specifications. Therefore, by normalizing the actual operation status index value using this standard value, it is possible to compare the operation status of elevators with different equipment specifications and operating conditions using the same scale (index, measure). Can be done. The key point of the present invention based on this idea is to obtain a driving condition evaluation value by normalizing the driving condition index with a reference value, and this driving condition evaluation value is calculated by the driving condition evaluation value calculation unit 17. .

The operation status evaluation value calculation unit 17 normalizes the operation status index calculated by the operation status index calculation unit 11 with the reference value (operation status reference value) calculated by the operation status reference value calculation unit 16, and calculates the operation status. Calculate the evaluation value. At this time, the driving state evaluation value calculation unit 17 executes the division shown in the following equation (1).
Operation status evaluation value = Operation status index value/standard value (operation status reference value)...(1)

The operation condition evaluation value calculation unit 17 normalizes (standardizes) the operation condition index by the operation condition reference value by executing the calculation according to equation (1), and calculates the operation condition evaluation value. , it is possible to compare elevators with different equipment specifications and operating conditions based on their operational status evaluation values. For example, the number of people using an elevator is an operational status indicator that is the most important factor determining elevator operation performance, but simply comparing the number of people using elevators with different equipment specifications and operating conditions will not be able to determine the effect. Can not. Therefore, we use the transportation capacity, which represents the number of people an elevator can transport per predetermined time, as the reference value, and perform the normalization calculation of number of users/transportation capacity (=operation status index/reference value) to obtain the operation status evaluation value. By obtaining this information, elevators with different equipment specifications and operating conditions can be compared based on the evaluation value of each elevator's operating status.

Furthermore, by introducing evaluation standard values that serve as a guideline for evaluating the quality of these operational status evaluation values and their impact on operational performance, it is possible to not only simply compare operational status evaluation values, but also to It is possible to evaluate the degree of influence of the state evaluation value. This evaluation standard value is calculated by the evaluation standard value calculation unit 19 based on the operation condition evaluation value data of the operation condition evaluation value DB 18 in which operation condition evaluation value data indicating the operation condition evaluation value of the elevator for each building purpose is stored. be done. The evaluation standard value calculation unit 19 statistically processes values that affect the operation status of elevators based on the data of operation status evaluation values classified by building use such as office buildings, condominiums, hotels, and complex buildings. The evaluation standard value can be calculated by For example, a statistical model such as a correlation analysis is used to calculate how the operational status evaluation value of the number of users/transport capacity affects the average waiting time of an elevator, which is an indicator of the quality of operational performance. Among the results, the value of the number of users/transport capacity in cases where the average elevator waiting time is a problem can be determined as the evaluation standard value.

The operation condition evaluation section 20 is based on the operation condition index calculated by the operation condition index calculation section 11, the operation condition evaluation value calculated by the operation condition evaluation value calculation section 17, and the evaluation reference value calculated by the evaluation reference value calculation section 19. Then, the operating state of the target elevator is evaluated by performing a comparative evaluation between the operating state index and the operating state evaluation value of different elevators, and a comparative evaluation between the operating state evaluation value of different elevators and the evaluation reference value. The former evaluation corresponds to relative evaluation, and the latter corresponds to absolute evaluation.

For example, by comparing the average waiting time of elevators in different buildings with the number of users/transport capacity, which is an evaluation value of the operation status, it is possible to objectively and relatively evaluate the influence of the number of users of each elevator on the average waiting time. be able to. For example, from the evaluation results, it is possible to understand the situation in which the number of people using the elevator in one building is concentrated when going to work, and it is also possible to estimate how much the number of people using the elevator should be reduced by staggered work hours etc. becomes.

In addition, to compare the operation status evaluation value and the evaluation standard value, for example, if the operation status evaluation value is the number of users / transportation capacity, compare the value of the number of users / transportation capacity of the target elevator with the evaluation standard value. By doing so, it is possible to understand (absolute evaluation), for example, the degree of influence of the number of users on the average waiting time.

As described above, the operation state evaluation unit 20 uses elevator operation state indicators (for example, average waiting time), operation state evaluation values (for example, number of users/transport capacity), and evaluation reference values (for example, number of users/transport capacity). Evaluates the operation status of the elevator based on the evaluation standard value (evaluation standard value) and outputs information indicating the evaluation result.

The result output unit 21 outputs information (information including image information) indicating the evaluation result by the driving state evaluation unit 20 to the information terminal 22. Here, the information output to the information terminal 22 can be changed according to the needs of the user using the information terminal 22.

For example, if the user using the information terminal 22 is a building owner, building manager, or building equipment manager, the information to be output to the information terminal 22 may include information on the operation status of the elevators in the building that the user owns in other buildings. Information that can be compared with elevators of other banks in the same building, or information that can identify the cause of poor elevator operation performance. It also includes information such as preliminary evaluation of what would happen if the operating conditions were to be changed in the event that the elevator's operating performance has deteriorated.

In addition, if the user of the information terminal 22 is an elevator maintenance company, the information output to the information terminal 22 may include, for example, understanding the causes of decline in elevator operating performance through relative evaluation or absolute evaluation, and making improvements. This includes information for considering countermeasures.

Furthermore, if the user of the information terminal 22 is a real estate developer or general contractor, the information to be output to the information terminal 22 may include, for example, the appropriate specifications of the elevator facilities and building specifications being considered when planning a building. This is information for considering whether or not the elevator is being used, and can be evaluated based on the evaluation results of the operating status of elevators that are actually in operation.

The information terminal 22 includes, for example, a display device such as a liquid crystal monitor, and displays information indicating the evaluation result by the driving state evaluation unit 20 on the display screen of the display device. This information terminal 22 basically displays and outputs information on the evaluation results of the operation status, but when the operation condition setting section 16 performs a preliminary evaluation in the event that the operation conditions are changed, It also serves as an input means for setting operating conditions.

When evaluating the operation status of an elevator, the elevator operation status evaluation device 1 of this embodiment evaluates the operation status index by combining the operation status index and the operation status evaluation value, or by combining the operation status evaluation value and the evaluation reference value. By evaluating, it becomes possible to appropriately compare and evaluate the operation status of elevators with different equipment specifications and operating conditions using the same scale, that is, a scale that includes the operation status evaluation value. As a result, the operating status of the target elevator can be objectively understood by comparing it with other elevators. In addition, if the operational performance of an elevator is deteriorating, such as due to a long average waiting time, it is possible to identify the cause of the deterioration of elevator operational performance by comparing the operational status index and the operational status evaluation value. can. Furthermore, by comparing the operation condition evaluation value with the evaluation standard value, it is possible to understand whether the operation condition of the target elevator is good or bad and the degree of influence of factors that degrade operation performance, which can be used to consider improvement measures. Furthermore, as one of the improvement measures, when changing the settings of the operating conditions, it is possible to calculate the evaluation value of the operational status in the case of the change, so it is possible to grasp the improvement effect of the change in advance.

FIG. 2 is a configuration diagram showing an example of the configuration of a building and an elevator that are targets of the elevator operation status evaluation device according to the present invention. FIG. 2A is a configuration diagram showing an example of the configuration of elevator groups in different buildings. In FIG. 2A, an elevator group 31 including a plurality of elevators is installed in a building 30, and an elevator group 33 including a plurality of elevators is installed in a building 32. When comparing the operating status of the elevators in Building 30 and Building 32, there are differences in the height of Buildings 30 and 32, the number of floors served, the number of elevators, the speed of the elevators, the capacity of the elevators, etc. It is difficult to compare the operation status of the elevators in both buildings 30 and 32.

FIG. 2(b) is a configuration diagram showing an example of the configuration of different banks in the same building. In FIG. 2(b), a low-rise bank 35 and a high-rise bank 36 are installed in the building 34. At this time, a non-stop floor 37 is set in the high-rise bank 36. When comparing the operation status of each elevator in the low-rise bank 35 and the high-rise bank 36, since the operation conditions of the elevators are different between the low-rise bank 35 and the high-rise bank 36, simply compare the operation status of each elevator in the low-rise bank 35 and the high-rise bank 36. It is difficult to compare.

FIG. 2C is a configuration diagram showing an example of this configuration in which the reference floor of the same elevator group in the same building is changed from the first floor to the second floor. In FIG. 2C, an elevator group 39 including a plurality of elevators is installed in the building 38. At this time, the reference floor 40 of the elevator group 39 may be changed from the first floor to the second floor. In this case, it is necessary to change the operating conditions for the elevator group 39. Therefore, for example, when comparing the elevator group 39 with other elevator groups, it is necessary to make a comparison that takes into account the operational conditions before and after the change.

If a building or elevator has the configuration shown in FIGS. 2(a) to 2(c), the operating status of elevators with different equipment specifications and operating conditions will be managed, but the elevator operating status evaluation device 1 may be used. This allows the operating status of elevators with different equipment specifications and operating conditions to be appropriately compared and evaluated using the same scale.

FIG. 3 is a display example of the information terminal according to the present embodiment, and is an explanatory diagram for evaluating the operating status of each elevator arranged in a plurality of buildings. Here, a case will be described as an example in which the operation status of elevator groups in two different buildings, for example, building A and building B, is compared and evaluated.

FIG. 3(a) is an explanatory diagram showing a display example when the operation status of the elevator groups in Building A and Building B is displayed by the number of people using the elevators. In FIG. 3A, the vertical axis is the number of people using the elevator, and the horizontal axis is Building A and Building B. Corresponding to building A, a graph 50 showing the number of people using the elevator in building A is displayed, and corresponding to building B, a graph 51 showing the number of people using the elevator in building B is displayed. Here, the number of people using the elevator is the number of people using the elevator per predetermined time (for example, 5 minutes), and can be calculated by the total number of people getting on the car, the total number of people getting off, the total number of people getting on and getting off, etc. The number of people getting on and off the car can be detected using changes in weight detected by the car's load sensor, image sensors inside the car, etc. In the case of Fig. 3(a), the graphs 50 and 51 are used to compare only the number of users, so if the equipment specifications and operating conditions of each elevator are different, it is difficult to simply compare the operating status of each elevator. is difficult.

On the other hand, FIG. 3(b) is an explanatory diagram showing a display example when the operation status of the elevator groups in building A and building B is displayed as an operation status evaluation value with respect to the number of users of the elevator. In FIG. 3(b), the vertical axis is the operation status evaluation value (calculated by the operation status evaluation value calculation unit 17) for the number of people using the elevator, and the horizontal axis is Building A and Building B. Corresponding to building A, a graph 52 is displayed that shows the evaluation value of the operation status with respect to the number of users of the elevator in building A. Corresponding to building B, a graph 53 showing the evaluation value of the operation status with respect to the number of users of the elevator in building B is displayed. is displayed.

At this time, the operational status evaluation value on the vertical axis is determined by using the operational status index (calculated by the operational status index calculation unit 11) as the number of users, and the reference value (calculated by the operational status reference value calculation unit 16) as the transportation capacity. / This is the value obtained from the transportation capacity calculation. This number of users/transportation capacity = operation status evaluation value is a value obtained by normalizing the number of users of an elevator by the transportation capacity that represents the equipment capacity of the elevator, and serves as an evaluation index that represents the state of the number of users based on the equipment capacity. . Therefore, by using the operating state evaluation value as a comparison target for both, it is possible to compare both using the same scale.

For example, in the case of FIG. 3(b), the elevator in building A has a larger operation status evaluation value (number of users/transport capacity) than that in building B (graph 52 is larger than graph 53), The situation is severe in terms of equipment capacity, and it can be inferred that the operational performance of the elevators in Building A is likely to be lower than that of the elevators in Building B. If this is simply compared based on the number of users, as shown in FIG. 3(a), the elevator in building A has a smaller value in graph 50 than the value in graph 51, and it appears that there is no problem. However, in this case, since the elevator in building A has a lower transportation capacity, it cannot be said that there is no problem. On the other hand, when comparing the operational state evaluation values that take transportation capacity into consideration, a proper evaluation can be performed as shown in FIG. 3(b).

FIG. 3(c) shows an example of a display in which the operation status of the elevator groups in Building A and Building B is displayed as an operation status evaluation value for the number of elevator users, and the evaluation standard value of the operation status evaluation value is also displayed. It is an explanatory diagram. In FIG. 3(c), the vertical axis is the operation status evaluation value for the number of people using the elevator, and the horizontal axis is Building A and Building B. Corresponding to building A, a graph 52 is displayed that shows the evaluation value of the operation status with respect to the number of users of the elevator in building A. Corresponding to building B, a graph 53 showing the evaluation value of the operation status with respect to the number of users of the elevator in building B is displayed. is displayed, and furthermore, an evaluation reference value 54 of the operating state evaluation value is displayed for the graphs 52 and 53. This evaluation standard value 54 is displayed as a broken line as an evaluation standard line for determining whether or not it affects the deterioration of elevator operation performance.

Here, the evaluation standard value 54 is a standard for evaluating whether the operation status evaluation value (=number of users/transportation capacity) has an impact on the operation performance of the elevator, such as the average waiting time, for example. . In this example, the graph 52, which is the evaluation value of the operation status of the elevator in building A, exceeds the evaluation standard value 54, so the number of users is large compared to the transportation capacity, and the operation performance of the elevator in building A is It can be determined that there is a possibility that it is decreasing.

Note that by setting this evaluation reference value 54 for each building use, the accuracy of the guideline for elevator operation performance degradation increases. For example, by setting evaluation standard values 54 for each building use, such as office buildings exclusive to one company, tenant office buildings, condominiums, and complex buildings, the degree of influence on operational performance deterioration can be determined according to the characteristics of elevator use for each building use. can be reflected in each evaluation standard value 54.

FIG. 4 is a display example of the information terminal according to the present embodiment, and is an explanatory diagram for evaluating the operation status of an elevator to be evaluated and an unspecified number of elevators. FIG. 4 is an explanatory diagram (conceptual diagram) showing a display example different from that in FIG. 3. In Figure 4, the vertical axis is the operation status evaluation value (=number of users/transport capacity) for the number of elevator users, and the horizontal axis is the average value for building A, all buildings, and the decline in operation performance. This is the average value for elevators. Corresponding to building A, the operation status evaluation value for the number of users of the elevator in building A is displayed in a graph 52, and corresponding to the average value of all buildings, the operation status evaluation value for the number of elevator users of all other buildings is displayed. The average value of the operation status evaluation values of the elevators whose operation performance has deteriorated is displayed as a graph 56, corresponding to the average value of the elevators whose operation performance has deteriorated.

4, the difference from the display example of FIG. 3(b) is that graphs 55 and 56 are displayed instead of graph 53 as values to be compared with graph 52. This does not select a specific building as an elevator in another building, but rather compares it with an unspecified number of elevators. For example, by comparing the graph 52 and the graph 55, it is possible to compare the average value of the operation status evaluation values of elevators in all other buildings and the status of the elevator to be evaluated. In addition, by comparing graph 52 and graph 56 (average values for elevators with degraded operating performance), it is possible to determine the possibility of a decline in the operating performance of the target elevator, and also to determine whether the operating performance has deteriorated. If so, it can be determined whether the item of the operation status evaluation value (for example, number of passengers/transport capacity in this example) is the cause of the decrease in operation performance. A method for evaluating the operating status by comparing graph 52 with graph 55 or graph 56 is to use the average value obtained from an unspecified number of elevators when it is difficult to identify elevators in other buildings to be compared. By using it, comparison becomes possible. Furthermore, it is also possible to determine the cause of the decline in elevator operating performance. In addition, the average value of the operation state evaluation value of an elevator can be calculated based on the data of the operation state evaluation value stored in operation state evaluation value DB18.

FIG. 5 is a configuration diagram showing an example of the configuration of an operating condition detection section belonging to the elevator operation state evaluation device according to the present invention. FIG. 5 shows details of the operating condition detection unit 14 shown in FIG. 1, and the same components as in FIG. 1 are denoted by the same reference numerals, and the description thereof will be omitted here.

The operating condition detection unit 14 detects the actual operating conditions of each elevator to be evaluated at the site, and uses the operating conditions detected here to determine the reference value of the operating condition ( The operating state reference value) is calculated by the operating state reference value calculation unit 16. This reference value of the operating condition is the key to evaluating the operating condition of the elevator, and it is important that it accurately reflects the actual operating condition of the elevator being evaluated. For this reason, the operating condition detection unit 14 performs a process of extracting the operating conditions actually operated at the site from the operation data of the elevator to be evaluated.

Specifically, the operating condition detection unit 14 includes a traffic condition detection unit 141, a stop floor detection unit 142, a door opening time detection unit 143, a reference floor detection unit 144, an occupancy rate detection unit 145, and a stop probability detection unit 146. . Data is provided to the operating condition detection unit 14 from the operation data remote collection device 9, the building specification/application database 12, and the equipment specification database 13, respectively.

The traffic condition detection unit 141 detects the traffic condition (also called traffic flow or traffic flow mode) of the target elevator based on the operation data collected by the operation data remote collection device 9, and outputs traffic condition data. Here, the traffic condition is a classification of the flow of people (mainly vertical flow) within a building. These traffic conditions include, for example, up-peak traffic where traffic is congested in the upward direction such as when going to work, up-peak traffic congestion, down-peak traffic congestion where the downward direction is congested such as during lunch or leaving work, down-peak traffic congestion, and bidirectional traffic congestion where both upward and downward directions are congested. There are crowded states, normal states, and quiet states.

Since elevator operating conditions are often set for each traffic condition, the traffic condition detection unit 141 detects the traffic condition and detects the elevator operating conditions for each traffic condition. For example, it is detected as the operating condition of the up-peak stop floor when going to work.

The stop floor detection unit 142 collects operation data collected by the operation data remote collection device 9, traffic condition data detected by the traffic condition detection unit 141, building specification/application data stored in the building specification/application database 12, Based on the equipment specification data stored in the equipment specification database 13, the stop floor (service floor) of the elevator to be evaluated is detected as the stop floor in actual operation, and stop floor data D1 is output.

The stopping floor in actual operation is set according to the operation of the building. For example, during peak hours such as when commuting to work, there are cases where elevators are operated by dividing the stopping floors into even-numbered floors and odd-numbered floors. This situation is detected by the stop floor detection unit 1142, the detected situation is stored as stop floor data D1, and the stored stop floor data D1 is used to calculate the operating state reference value.

The door open time detection unit 143 uses the operation data collected by the operation data remote collection device 9, the traffic condition data detected by the traffic condition detection unit 141, and the equipment specification data stored in the equipment specification database 13 to The door opening time of the elevator to be evaluated is detected as the door opening time in actual operation, and door opening time data D2 is output. The standard floor detection unit 144 collects the operation data collected by the operation data remote collection device 9, the building specification/application data stored in the building specification/application database 12, and the equipment specification data stored in the equipment specification database 13. Based on this, the reference floor (main lobby floor) of the elevator to be evaluated is detected as the reference floor in actual operation, and reference floor data D3 is output. The occupancy rate detection unit 145 determines the actual situation based on the operation data collected by the operation data remote collection device 9, the traffic condition data detected by the traffic condition detection unit 141, and the equipment specification data stored in the equipment specification database 13. The occupancy rate of the elevator to be evaluated is detected as the occupancy rate in the operation of the elevator, and occupancy rate data D4 is output.

The stop probability detection unit 146 determines the actual situation based on the operation data collected by the operation data remote collection device 9, the traffic condition data detected by the traffic condition detection unit 141, and the stop floor data detected by the stop floor detection unit 142. As the stop probability for each stop floor in the operation of the elevator, the stop probability for each stop floor of the elevator to be evaluated is detected, and stop probability data D5 is output. This stop probability becomes important data for calculating one round time, which is essential in traffic calculation when calculating the reference value of the operating state by the operating state reference value calculation unit 16. By setting the stop probability for each stop floor based on the actual operating state, it is possible to calculate a more accurate one-round time, and it is possible to perform a more accurate evaluation of the operating state.

FIG. 6 is a schematic diagram showing the configuration of a building for explaining the operating conditions of elevators targeted by the elevator operating state evaluation device according to the present invention. FIG. 6(a) is a schematic diagram showing the configuration at the time of building planning, and FIG. 6(b) is a schematic diagram showing the configuration after the building is in operation.

As shown in FIG. 6(a), in the building 60 from the B1 floor to the 12th floor, during building planning, each floor from the B1 floor to the 12th floor is set as a stop floor (service floor) indicated by a circle, and the first floor is set as the standard floor. On the other hand, as shown in Figure 6(b), after the building is in operation, among the B1 to B12 floors, the B1 to 4th floors and the 7th to 11th floors are the stop floors (service floors) marked with a circle. is set, and the standard floor is changed from the first floor to the second floor. In other words, after the building is in operation, the usage of each floor of Building 60 will change depending on the tenants and floor usage at that time, so there are cases where the usage changes from the time of planning, and even after that, there is a possibility that it will continue to change depending on the tenant and usage. There is. The standard floor (main lobby floor) may also change as shown in Figure 6 due to the construction of a new railway station or the installation of a pedestrian deck.

Since such a change greatly affects the operating condition of the elevator, the operating condition detection unit 14 described in FIG. 5 is configured to detect the change and reflect it in the operating condition reference value. That is, in order to cope with such a case, the operating condition detection unit 14 includes processing for detecting the actual operating conditions at that time.

FIG. 7 is a configuration diagram showing an example of the configuration of an operation condition reference value calculation unit belonging to the elevator operation condition evaluation device according to the present invention.

The operation status reference value calculated by the operation status reference value calculation unit plays an important role in the embodiment of the elevator operation status evaluation device according to the present invention, and in this embodiment, differences in equipment specifications and operating conditions are Operating condition reference values for normalization are calculated based on the "traffic calculation" model.

FIG. 7 will be explained below. In FIG. 7, the same parts as in FIGS. 1 and 5 are denoted by the same reference numerals, and their explanation will be omitted.

The operation state reference value calculation unit 16 includes a number of passengers/number of passengers getting off the train 161, a boarding/disembarking time calculation unit 162, a total stop time calculation unit 163, a running distance/running time calculation unit 164, a one-round time calculation unit 165, and a total number of passengers. It includes a calculation section 166, a 5-minute transportation capacity calculation section 167, an average number of stops calculation section 168, an operating number calculation section 169, and an average driving interval calculation section 16A. The operation condition reference value calculation unit 16 includes equipment specification data (car capacity data) from the equipment specification database 13, traffic condition data detected by the traffic condition detection unit 141 (car speed data, acceleration data), Stop floor data detected by the stop floor detection unit 142 , stop probability data detected by the stop probability detection unit 146 , reference floor data detected by the reference floor detection unit 144 , building specifications and usage stored in the building specification and usage database 12 The door opening time data detected by the door opening time detection unit 143 is provided as input data. Using these input data, the operation status reference value calculation unit 16 calculates transportation capacity (5-minute transportation capacity), one-round time (average one-round time), and average operation interval based on the elevator operation model based on traffic calculation. , a reference value of the operating condition such as the average number of stops per lap is calculated as the operating condition reference value.

Here, first, the one-round time of an elevator, which is the basis of traffic calculation, will be explained using FIG. 8. FIG. 8 is a schematic diagram showing a calculation model for one revolution time of an elevator used by the operation state reference value calculation unit according to the present embodiment. In FIG. 8, the vertical axis is the floor of the building indicating the position of the elevator car, and the horizontal axis is time indicating the time axis of the elevator. Graph 80 is a line showing the elevator operation trajectory from time t1 to t16. This graph 80 shows that an elevator car departs from a reference floor, moves upward, stops at a floor where a landing call or a car call occurs, and then moves downward due to a downward operation, and the car also receives a car call. This shows the operating state in which the train returns to the standard floor after stopping at the floor where the train occurred. The time required for one round of an elevator car to return to the standard floor after departing from the standard floor is one round time. If the one-round time is long, the elevator waiting time and boarding time will be longer, so the one-round time is an important item related to the operation status of the elevator. Furthermore, the transportation capacity, which represents the number of people transported by an elevator per hour, is calculated as the number of people carried by the elevator in one round of time, so the time of one round is also important.

The elements that constitute this one round time are elevator stopping times, e.g., times t1, t3, t5, t7, t9, t11, t13, t15, and elevator running times, e.g., times t2, t4, t6, t8. , t10, t12, t14, and t16. For elevators, the total stop time (total stop time = t1 + t3 + t5 + t7 + t9 + t11 + t13 + t15) is a more dominant factor in one revolution than the running time, so the number of elevator stops is becomes important.

Therefore, in order to more accurately estimate the time for one round of the target elevator, data and calculation methods for more accurately estimating the number of stops, stopping time, and running time of the elevator are important. The operation state reference value calculation unit 16 in FIG. 7 performs processing that takes this into consideration.

The description of FIG. 7 will now be returned to. The number of people getting on/off the train 161 calculates equipment specification data (car capacity data) from the equipment specification database 13 , traffic condition data detected by the traffic condition detection section 141 , and stop floor data detected by the stop floor detection section 142 . Based on this, the number of people getting on and getting off each stop floor is calculated, and the number of people data indicating the number of people getting on and getting off each stop floor is output. The boarding/alighting time calculation unit 162 calculates the elevator boarding/alighting time of passengers at each stop floor, for example, the elevator boarding/alighting time per passenger, based on the number of people data calculated by the boarding/alighting number calculation unit 161. Outputs boarding and alighting time data indicating the time it takes to get on and off the elevator.

The total stop time calculation unit 163 calculates stop floor data (detection data of the stop floor detection unit 142), stop probability data for each stop floor (detection data of the stop probability detection unit 145), door opening time data (door opening time detection unit 143 detection data) and the boarding and alighting time data (detection data of the boarding and alighting time detection unit 162) indicating the boarding and alighting time of passengers for each stopping floor, the total stopping time per elevator revolution is calculated, and the total stopping time per elevator revolution is calculated. Outputs total stop time data indicating the total stop time. Further, the total stop time calculation unit 163 calculates an average stop time from the calculation result of the total stop time per revolution of the elevator, and outputs average stop time data D6 indicating the average stop time.

The travel distance/traveling time calculation unit 164 calculates data stored in the equipment specification database 13 (equipment specification data), data stored in the building specification/application database 12 (building specification data), and traffic condition data (car speed. data, car acceleration data), calculates the travel distance and travel time of the target elevator (see Figure 8), and outputs travel distance data and travel time data indicating the travel distance and travel time of the target elevator. .

The one-round time calculation unit 165 calculates the total stop time per round of the elevator (total stop time data) calculated by the total stop time calculation unit 163 and the travel distance/travel of the elevator calculated by the travel distance/travel time calculation unit 164. One round time of the elevator (average one round time) is calculated based on the time (traveling distance data/traveling time data), and one round time data (average one round time) indicating the one round time of the elevator (average one round time) is calculated. Data) Output D7. At this time, the one-round time calculation unit 165 calculates the one-round time of the elevator with reference to the model of the operating state of one round of the car explained with reference to FIG. This one-round time can be calculated by the sum of the total stopping time and running time. This one-round time becomes one of the reference values (operation status reference values).

The total number of passengers calculation unit 166 calculates the total number of passengers per round of the elevator car based on the number of people calculated by the number of people getting on/off the car 161 and the one-round time data calculated by the one-round time calculation unit 165. The number of passengers is calculated and the total number of passengers data indicating the total number of passengers per revolution of the elevator car is output.

The 5-minute transportation capacity calculation unit 167 calculates the number of people transported by the elevator per 5 minutes based on the one-round time data calculated by the one-round time calculation unit 165 and the total number of passengers data calculated by the total number of passengers calculation unit 166. The 5-minute transportation capacity expressed is calculated, and 5-minute transportation capacity data D8 indicating the transportation capacity of the elevator per 5 minutes is output. This 5-minute transportation capacity serves as a reference value for the number of people using the elevator.

The average number of stops calculation unit 168 calculates the number of stops based on the one-round time data calculated by the one-round time calculation unit 165, the stop probability data detected by the stop probability detection unit 146, and the stop floor data detected by the stop floor detection unit 142. Then, the average number of stops per revolution of the elevator is calculated, and average number of stops data D9 indicating the average number of stops per revolution of the elevator is output. At this time, as explained with reference to FIG. 8, the number of stops per round is an important factor that determines the time for one round, so the average number of stops per round also serves as a reference value for the operating state. Furthermore, although not shown in Figure 7, the number of stops includes the number of car call stops and the number of car call stops. It is possible to calculate the number of car call stops and the average number of car call stops per round. These also serve as reference values for operating conditions.

The operating number calculation unit 169 calculates the actual number of operating elevators based on the operation data of the elevator to be evaluated, and outputs operating number data indicating the actual number of operating elevators. The number of operating vehicles is also an important item because, for example, the number of operating vehicles may be limited at night, or the number may be reduced due to dedicated operation during the day, and a reduction in the number of vehicles will strongly affect operational performance.

The average operating interval calculation unit 16A calculates the average operating interval of the elevator based on the one-round time data calculated by the one-round time calculation unit 165 and the operating number data calculated by the operating number calculation unit 169, and calculates the average operating interval of the elevator. Average driving interval data D10 indicating the average driving interval is output. This average operation interval corresponds to the average arrival interval of elevator cars to a given floor, and is an important value related to the average waiting time. Therefore, the average driving interval serves as a reference value for the operating state with respect to the average waiting time (average platform call duration).

As described above, the operation condition reference value calculation unit 16 calculates the actual operation conditions detected from the operation data (stop floor data D1, door opening time data D2, reference floor data D3, occupancy rate data D4, stop probability data D5). , elevator equipment specification data, building building specification data, etc. are input data, and based on traffic calculation, which is a theoretical model of operation status, transportation capacity (5-minute transportation capacity), stop time (average stop time), The time per round (average time per round), average operation interval, and average number of stops per round are calculated based on the actual operation status of the elevators at the site. These values are applied as operating condition reference values based on actual elevator operating conditions. As a result, in a comparative evaluation of elevators in different buildings, it becomes possible to evaluate the operation status of each elevator that appropriately reflects the local operation status of each elevator.

FIG. 9 is a configuration diagram showing an example of the configuration of an operation status evaluation value calculation unit belonging to the elevator operation status evaluation device according to the present invention. Here, the contents of the process performed by the driving state evaluation value calculation unit 17 explained in FIG. 1 will be explained.

In FIG. 9, the operation state evaluation value calculation unit 17 includes a division processing unit 171 that executes a division process of the operation state index/operation state reference value. The division processing unit 171 takes in data indicating the calculation result of the operation status index calculation unit 11 (operation status index of the elevator) and the calculation result of the operation status reference value calculation unit 16 (reference value for the elevator operation status index), and Based on these input data, the operation status index is divided by the operation status reference value (operation status reference value) (calculation process of formula (1)), and the operation status evaluation is the evaluation value for the operation status. The value is calculated, and operation status evaluation value data, which is data of the evaluation value for the operation status of the elevator, is output to the operation status evaluation value DB 18. This division processing means normalizing the operating state index with the corresponding reference value.

As already explained, it is not possible to simply compare the operation status of elevators in different buildings by simply using the operation status index itself, such as the number of people using the elevator. However, the operation status index is normalized with a standard value such as transportation capacity that reflects equipment specifications and operational conditions, and the operation status evaluation value obtained by normalizing (standardization) the operation status index with the reference value is compared. By using it for evaluation, it is possible to compare the operation status of elevators in different buildings. This operation status evaluation value is managed in an index management table.

FIG. 10 is a configuration diagram showing an example of the configuration of the index management table according to this embodiment. The index management table 100 is a table in which specific examples of operation status indicators, reference values, and operation status evaluation values are organized and recorded, and is a model of important evaluation indicators that are the basis of the elevator operation status evaluation device 1. become.

In FIG. 10, the index management table 100 includes No. It includes the following items: (number) 101, classification 102, operational status (when operational performance deteriorates) 103, operational status index 104, reference value 105, and operational status evaluation value 106, and is stored in the storage device.

No. (Number) 101 stores information on numerical values (“1” to “9”) indicating numbers for dividing the contents of the index management table 100 into nine items. In order to classify the indicators into two types, the classification 102 stores information on a first category of "indicators for operational performance" and information on a second category of "indicators for causes of deterioration in operational performance."

Corresponding to the ``indicators for operation performance'' of the first category, the operation status status (when operation performance deteriorates) 103 includes ``Long waiting time for elevators'', ``Long waiting time for elevators'', ``Long car "is crowded" information is stored. The operation status index 104 includes information such as "average platform call duration", "long wait occurrence rate of 60 seconds or more", and "average car occupancy rate" as the operation status index for the first classification calculated by the operation status index calculation unit 11. is stored. The reference value 105 stores information such as "average driving interval", "-", and "maximum allowable value of average occupancy rate" as the reference value for the first classification calculated by the operation state reference value calculation unit 16. The operation status evaluation value 106 includes the following information as the operation status evaluation value for the first classification calculated by the operation status evaluation value calculation unit 17: "average platform call duration/average driving interval", "long wait occurrence rate of 60 seconds or more", and "boarding status evaluation value". The information "average car occupancy rate/maximum allowable value of average occupancy rate" is stored. Note that the average driving interval is a value calculated from traffic calculations, and the maximum permissible value for the average car occupancy rate is a value that is separately set as a permissible value.

Corresponding to the second classification "Indicators for factors causing deterioration of operational performance", the operational state status (when operational performance deteriorates) 103 includes "the number of people using the elevator is large" as the operational state for the second classification. “The car takes a long time to complete one lap” “The car stops many times per lap” “The car stops many times due to landing calls” “The car stops many times due to car calls” “The car stops for a long time” information is stored. The operation status index 104 includes “number of users,” “average time per lap (actual data),” and “average number of stops per lap (actual data) as the operation status index for the second classification calculated by the operation status index calculation unit 11. ), "Average number of car call stops per lap (actual data)," "Average number of car call stops per lap (actual data)," and "Average stopping time for one stop (actual data)" are stored. be done. The reference value 105 includes "transport capacity", "time per lap (traffic calculation)", "number of stops per lap (traffic calculation)", as the reference value for the second classification calculated by the operating condition reference value calculation unit 16. Information such as the number of car call stops per round (traffic calculation), the number of car call stops per round (traffic calculation), and the stopping time for one stop (traffic calculation) is stored. The operation status evaluation value 106 includes the following information as the operation status evaluation value for the second classification calculated by the operation status evaluation value calculation unit 17: "Number of users/Transportation capacity", "Average one round time (actual data)/One round time (traffic Calculation) "Average number of stops per lap (actual data) / Number of stops per lap (traffic calculation)" "Number of platform call stops per lap (actual data) / Number of platform call stops per lap ( Traffic calculation)” “Average number of car call stops per lap (actual data) / Number of car call stops per lap (traffic calculation)” “Average stopping time for one stop (actual data) / One stop Information on "stopping time (traffic calculation)" is stored.

Here, when using the information in the index management table 100, if it is determined that the operating state of the elevator (when the operating performance is degraded) is "long elevator waiting time", the "average When one of the information "Passage call duration" and "Long wait occurrence rate of 60 seconds or more" is used, and "Average platform call duration" is used as the operation status index 104, "Average platform call duration" is used as the information of the reference value 105. The average driving interval is used, and the information obtained by calculating the average platform call duration/average driving interval is used as the information of the operation status evaluation value 106.

In addition, when the operating state of the elevator (when the operating performance deteriorates) is determined to be that "the number of people using the elevator is large", the information on "number of users" is used as the operating state index 104, and the reference value 105 is "Transportation capacity" is used as the information, and information obtained by calculating the number of users/transportation capacity is used as the information on the operation state evaluation value 106.

The information recorded in the operational status evaluation value 106 is a value obtained by normalizing (dividing) the information on the operational status index 104 by the information on the reference value 105, as described above.

Here, we will explain how to distinguish between indicators for operation performance and indicators for factors that degrade operation performance.In evaluating the operation status of the target elevator, the first important indicator is an indicator for operation performance such as the average platform call duration. becomes. Therefore, when evaluating the operational status, this is shown first. On top of that, if there is a decline in the operational performance, each index that is a factor in the operational performance is indicated as an item that is a factor, and the cause of the operational performance decline is extracted. For example, based on the evaluation value corresponding to the number of passengers and the evaluation value corresponding to the time per round, it is possible to find out whether the number of passengers is large compared to the transport capacity is the cause of the decline in operational performance, or the long one-round time is the cause of the decline in transport performance. Determine whether it is a contributing factor. As a result, if the cause of the decline in operational performance can be identified, measures can be taken to improve the cause, and it becomes possible to carry out everything from evaluating the operational state to formulating improvement measures.

FIG. 11 is a configuration diagram showing an example of the configuration of an evaluation reference value calculation unit belonging to the elevator operation state evaluation device according to the present invention. FIG. 11 shows details of the evaluation reference value calculation unit 19 shown in FIG. 1.

Here, the evaluation reference value is a value that indicates how much the operation status evaluation value influences the operation status of the elevator. This evaluation standard value corresponds to, for example, the evaluation standard value 54 in FIG. 3(c). For example, when the evaluation standard value is an index for the operational performance described in the index management table 100, it becomes a standard for determining the deterioration of the operational performance of an elevator, and when it is an index for the cause of the deterioration of the operational performance of the elevator, This is the standard for determining whether or not this is a factor. In this embodiment, an evaluation standard value is assumed to be used as a standard for determining the latter factor that causes a decline in driving performance.

FIG. 11 will be explained below. In FIG. 11, the same parts as in FIG. 1 are given the same reference numerals, and their explanation will be omitted.

The evaluation standard value calculation unit 19 includes a building usage detection unit 191, a traffic condition detection unit 192, a driving performance evaluation unit 193, an evaluation level DB 194, an evaluation standard value setting unit 195, and a statistical value calculation unit 196. The evaluation standard value calculation unit 19 is provided with the building specification/application data stored in the building specification/application database 12 and the operation condition evaluation value data stored in the operation condition evaluation value DB 18 as input data.

At this time, the building specification/purpose database 12 includes, for example, data regarding building usage such as office building types exclusive to one company, types consisting of many tenants, types consisting of a small number of tenants, condominium building types, Data classified by building use is stored, such as commercial building types such as department stores and shopping centers, complex building types, large-scale hospital types, hotel types, school types, etc. These data are used to set evaluation standard values for each building use. The reason for this is that evaluation standard values are set for each building use because the operating status characteristics differ depending on the building use.

The building use detection unit 191 detects the use of the building in which the elevator to be evaluated is installed based on the building specification/use data stored in the building specification/use database 12, and generates building use data indicating the use of the building. Output. The traffic condition detection unit 192 detects the elevator traffic condition with respect to the operation condition evaluation value based on the operation condition evaluation value data stored in the operation condition evaluation value database 18, and generates traffic condition data indicating the elevator traffic condition. Output. This traffic condition is detected in order to set an evaluation reference value for each traffic condition, similarly to the building use.

The operation performance evaluation unit 193 evaluates each performance item based on the data stored in the evaluation level DB 194 and indicating a plurality of operation performance items and the evaluation level data indicating the evaluation level of good or bad (good or bad) for each performance item. For operational performance items, evaluation levels are used to evaluate whether or not operational performance has deteriorated, and operational performance evaluation data is output as the evaluation result. For example, it is determined whether the average platform call duration, which is an operation performance item, exceeds the evaluation level, and if the average platform call duration exceeds the evaluation level, it is determined that the operation performance has deteriorated. Outputs operational performance evaluation data shown. Here, the operation performance items are, among the information belonging to the operation status index 104 of the index management table 100, "average platform call duration," "proportion of waiting occurrences that are longer than 60 seconds," "average car occupancy rate (crowded boarding (Information belonging to the first classification operation status index).

The evaluation reference value setting unit 195 uses the operation state evaluation value data stored in the operation state evaluation value DB 18, the building usage data detected by the building usage detection unit 191, the traffic state data detected by the traffic state detection unit 192, and Based on the operation performance evaluation data evaluated by the operation performance evaluation unit 193, the operation condition evaluation value (operation condition evaluation value for second classification) for the cause of the elevator operation performance deterioration is determined to be the cause of the elevator performance deterioration. Set the evaluation standard value. At this time, the evaluation standard value setting unit 195 sets evaluation standard values using machine learning and statistical methods based on a large amount of data stored in the building specification/application database 12 and the operation status evaluation value DB 18. Furthermore, since this evaluation standard value is considered to differ for each building use and each traffic condition, the evaluation standard value setting unit 195 sets the evaluation standard value for each building use and each traffic condition. In other words, the evaluation reference value setting unit 195 sets evaluation reference values for factors of operational performance deterioration for each building use and traffic condition.

The evaluation standard value set by the evaluation standard value setting unit 195 is used as an evaluation standard value for determining which item is involved in the cause of the decline in elevator operation performance. For example, by comparing the operational status evaluation value for a factor of operational performance deterioration (for example, number of passengers/transportation capacity) with this evaluation reference value, it is possible to determine whether this is a factor. For example, as shown in Fig. 3(c), by comparing the operation status evaluation value for the number of elevator users with the evaluation standard value 54, it is found that the reason for the decline in the operation performance of the elevator in Building A is that the number of users is It can be judged that this is a lot compared to the ability.

The statistical value calculation unit 196 calculates the operation state evaluation value data stored in the operation state evaluation value DB 18, the building usage data detected by the building usage detection unit 191, the traffic state data detected by the traffic state detection unit 192, and the operation state evaluation value data stored in the operation state evaluation value DB 18. Based on the operation performance evaluation data evaluated by the performance evaluation unit 193, for example, the average value of the operation condition evaluation values for the factors of elevator operation performance deterioration is calculated as the statistical value of the operation condition evaluation values for the factors of elevator operation performance deterioration. , calculated by building use and traffic condition. The average value calculated by the statistical value calculation unit 196 is used, for example, as the average value for all buildings, as shown in graph 55 in FIG. Used as a value. In addition, the average value calculated by the statistical value calculation unit 196 is a reference value for evaluating the operation status evaluation value of other buildings with respect to the operation status evaluation value of the elevator to be evaluated, and is especially used as a reference value for evaluating the operation status evaluation value of other buildings. It can be used as a reference value for objective evaluation when comparing with the average value of buildings where performance deterioration has occurred.

FIG. 12 is a schematic diagram for explaining a method of setting an evaluation reference value in the evaluation reference value setting section belonging to the elevator operation state evaluation device according to the present invention.

In FIG. 12, the vertical axis is the average platform call duration (operational performance value), which indicates the operational status index, and the horizontal axis is the number of users/transport capacity, which indicates the operational status evaluation value, which is a factor of operational performance deterioration. . For the average platform call duration (operation status index) on the vertical axis, an evaluation level of 120, which is a standard level for operational performance deterioration, is shown. If the average hall call duration, which indicates the operational performance value of the elevator, exceeds the evaluation level 120, it is determined that the average hall call duration is long and the operational performance has deteriorated.

Based on this standard level of operational performance deterioration, an evaluation reference value at which operational performance deterioration occurs is set. At this time, data D11 to D19 (data marked with black circles) of average platform call duration, which indicates the operation status index for the number of users/transportation capacity, which is the operation status evaluation value, is plotted as data for an office building exclusive to one company. As data for a multi-tenant office building, data D21 to D37 (white mark data) of average platform call duration indicating an operational status index for the number of users/transportation capacity, which is an operational status evaluation value, are plotted.

A characteristic line 121 is set between the data D11 to D19, which are the plot points, and which shows the relationship between the operational state evaluation value and the operational state index, which are factors for office buildings exclusively used by one company, and the data D21 to D19, which are the plot points. Between D37, a characteristic line 122 is set that indicates the relationship between the operational state evaluation value and the operational state index, which are factors for a multi-tenant office building.

In the case of an office building exclusively owned by one company, the evaluation standard value at which the operational performance deteriorates is a line from the characteristic line 121 and the evaluation level 120 that corresponds to the operational state evaluation value at the point where the characteristic line 121 and the evaluation level 120 intersect. It is set to a value of 123. Similarly, in the case of a multi-tenant office building, the evaluation standard value at which the operational performance deteriorates corresponds to the operational status evaluation value at the intersection of the characteristic line 122 and the evaluation level 120, based on the characteristic line 122 and the evaluation level 120. is set to the value of line 124.

By using such a method, the evaluation reference value setting unit 195 can set evaluation reference values for factors of operational performance deterioration for each building use. Note that the evaluation reference value setting unit 195 can also set evaluation reference values for factors of driving performance deterioration for each traffic condition using a similar method.

As a supplement, characteristic line 121 showing the relationship between the operational status evaluation value and operational status index, which is a factor for a single-tenant office building, is better than the operational status evaluation value and operational status index, which is a factor for a multi-tenant office building. The reason why the slope is larger than the characteristic line 122 indicating the relationship with the state index will be explained. In the case of an office building exclusively owned by one company, there is a lot of movement by elevator between each floor because it is the same company, and even if the number of users is the same, there is a lot of movement between floors, so the number of elevator stops is large, and the time for one round is shortened. Since the average landing call duration time becomes longer, the slope becomes larger. Since the characteristics of elevator use differ depending on the building use, it is preferable to also set the evaluation standard value for each building use, which causes a decrease in operating performance.

FIG. 13 is a functional block diagram for explaining the processing of the operation state evaluation unit belonging to the elevator operation state evaluation device according to the present invention. FIG. 13 shows the processing contents of the driving state evaluation unit 20 shown in FIG. 1.

The outline of the process shown in FIG. 13 is to evaluate the operation status of the target elevator by first determining whether or not performance has deteriorated with respect to the operation status index related to operation performance. If so, the operation condition evaluation value related to the deterioration in operation performance and its evaluation reference value are used to evaluate whether the item of the operation condition evaluation value is a factor of the performance deterioration. Using the operational status index related to operational performance and the operational status evaluation value and evaluation reference value related to the factors of performance deterioration, the operational status is evaluated and the cause of performance deterioration is determined.

In FIG. 13, the operation state evaluation unit 20 inputs the operation state index X related to the operation performance of the elevator from among the operation state indicators for the first classification as the calculation result of the operation state index calculation unit 11, and It is determined whether the operation performance (average waiting time) is decreasing with respect to the operation state index X (for example, average platform call duration) related to operation performance (B201). At this time, the operation state evaluation unit 20 determines, for example, whether the value of the operation state index X related to the operation performance of the elevator, that is, the average platform call duration time, exceeds an evaluation level that is a guideline for a decrease in operation performance. do.

If it is not determined that the performance has deteriorated with respect to the operation state index X, the operation state evaluation unit 20 selects No. 1 of the index management table 100 as the next operation state index 2, "Long waiting occurrence rate of 60 seconds or more" is selected (B202), and it is determined whether the operation performance (waiting time) is decreasing with respect to the selected operation state index (B201). If no performance deterioration is determined for the operation state index X, the next operation state index X is, for example, No. No. 3 "average car occupancy rate" is selected (B202), and it is determined whether the operation performance (average waiting time) is decreasing with respect to the selected operation state index (B201). These processes are performed according to No. of the index management table 100. This process is carried out until all the information recorded in the first to third operating state indicators 104 (information indicating the first classification operating state indicators) is selected.

On the other hand, when it is determined that the performance has deteriorated with respect to the operation condition index Input the condition evaluation value Y (for example, number of passengers/transportation capacity) from among the operation condition evaluation values for the second classification, and input the evaluation standard value as the calculation result of the evaluation standard value calculation unit 19 to determine whether the operational performance has deteriorated. It is determined whether the driving state evaluation value Y related to the factor is larger than the evaluation reference value (B203). That is, the operation condition evaluation unit 20 determines whether or not there is a possibility that the decrease in performance with respect to the operation condition index X is caused by the operation condition evaluation value Y.

When the operational status evaluation value Y is not larger than the evaluation reference value, that is, when the operational status evaluation value Y is not determined to be a factor of performance deterioration, the operational status evaluation unit 20 calculates the operational status evaluation value Y for the next factor. For example, No. of the index management table 100. 5, "1 lap time (actual data)/1 lap time (traffic calculation)" is selected (B204), and it is determined whether the selected operation status evaluation value Y is larger than the evaluation reference value (B203). . These processes are performed according to No. of the index management table 100. This process is carried out until all the information recorded in the operating state evaluation values 106 of 4 to 9 (information indicating the operating state evaluation values for the second classification) is selected.

On the other hand, if the operation condition evaluation value Y is larger than the evaluation reference value, that is, if the operation condition evaluation value Y is determined to be a factor of performance deterioration, the operation condition evaluation unit 20 determines whether the operation condition represented by the operation condition index It is determined that there is a possibility that a factor corresponding to the operational state evaluation value Y may be influencing the performance deterioration (B205), and as a determination result, the evaluation result of the operational performance deterioration and the evaluation result of the factor are output ( B206). Note that when it is determined in block B201 that the performance has deteriorated with respect to the operation state index X, the operation state evaluation unit 20 selects No. As the determination results for the information recorded in the operational status indicators 104 1 to 3, the evaluation results of operational performance deterioration and the factors thereof are output (B206). In addition, in block B201, when determining whether or not the operation performance has deteriorated with respect to the operation condition index X, the operation condition evaluation value corresponding to the operation condition index X (= average platform call duration / average operation Deterioration in performance can also be determined by comparing the interval) with the evaluation reference value.

FIG. 14 is a configuration diagram showing an example of the configuration of the operating condition setting section belonging to the elevator operating state evaluation device according to the present invention. FIG. 14 shows details of the operating condition setting section 15 shown in FIG. 1.

In FIG. 14, the same components as in FIG. 1 are designated by the same reference numerals, and their description will be omitted.

In FIG. 14, the operation condition setting section 15 includes a stop floor setting section 151, a door opening time setting section 152, a reference floor setting section 153, and an occupancy rate limit value setting section 154, and each section is connected to the operation condition detection section 14 and information It is connected to the terminal 22. When the operating condition detection unit 14 detects the current operating conditions for the elevator to be evaluated, the operating condition data indicating the current operating conditions for the elevator to be evaluated are the stop floor data D1, the door opening time data D2, and the standard. Floor data D3 and occupancy rate data D4 are each input to the operation condition setting section 15. At this time, for example, when a change command is input from the information terminal 22 to the operating condition setting unit 15, the operating condition setting unit 15 executes the process of changing the operating conditions in response to the change command. The operating condition setting unit 15 changes the operating condition data detected by the operating condition detecting unit 14, for example, according to a setting value commanded from the information terminal 22, and sets the changed operating condition data as changed operating condition data as an operating condition. It is sent back to the detection unit 14.

Specifically, for example, the stop floor setting unit 151 changes the stop floor data D1 according to the first set value, and uses the changed stop floor data as the stop floor set value P1 indicating the changed operation condition data as the operating condition. It is sent back to the detection unit 14. The door opening time setting section 152 changes the door opening time data D2 according to the second setting value, and uses the changed door opening time data as the door opening time setting value P2 indicating the changed operating condition data as the operating condition detection section 14. send it back to The reference floor setting unit 153 changes the reference floor data D3 according to the third setting value, and returns the changed reference floor data to the operating condition detection unit 14 as the reference floor setting value P3 indicating the changed operating condition data. The occupancy rate limit value setting unit 154 changes the occupancy rate data D4 according to the fourth setting value, and uses the changed occupancy rate limit value data as the occupancy rate limit setting value P4 indicating changed operational condition data to the operation condition detection unit. Return it on 14.

At this time, the operation condition reference value calculation section 16, which receives each changed operation condition data from the operation condition detection section 14, changes the operation condition reference value calculated before the operation condition change based on the changed operation condition data. Then, the changed operating condition reference value is generated. The operation condition evaluation value calculation unit 17, which inputs the changed operation condition reference value from the operation condition reference value calculation unit 16, changes the operation condition evaluation value calculated before the change of the operation condition based on the changed operation condition reference value. Then, a changed operation status evaluation value is generated. The evaluation standard value calculation unit 19 that inputs the changed operational state evaluation value changes the evaluation standard value calculated before the change of the operational conditions based on the changed operational state evaluation value, and generates the changed evaluation standard value. do.

The operation condition evaluation unit 20, which inputs the changed operation condition evaluation value and the changed evaluation reference value, evaluates the operation condition of each elevator after the operation condition is changed based on the changed operation condition evaluation value and the changed evaluation reference value. evaluate. At this time, the operation condition evaluation unit 20 retains the information input before the operation conditions are changed, and based on the information input before and after the operation conditions are changed, the operation condition evaluation unit 20 Elevator operation status can be evaluated.

When the operating conditions are changed, the changed contents are reflected in the detection results and reference values of the operating condition detection unit 14, so data on the operating status of elevators in other buildings etc. From this, it is possible to estimate the extent to which the operational status (operational status index related to operational performance, operational status evaluation value related to factors of operational performance deterioration, etc.) will be improved.

This can be used to improve the operating conditions of elevators that are already in operation, or to improve the expected operating conditions by adjusting elevator specifications at the time of planning.

FIG. 15 is a schematic diagram showing a first display example when the elevator operating state is evaluated by the elevator operating state evaluation device according to the present invention. This first display example is an image displayed on the screen of the information terminal 22, and image information of this image is generated by the driving state evaluation section 20 and the result output section 21. Note that the second to fourth display examples described below are also images displayed on the screen of the information terminal 22, and the image information of these images is generated by the operation status evaluation unit 20 and the result output unit 21. Ru.

FIG. 15A is a schematic diagram showing a first display example in which operation status indicators of elevators in different buildings are compared and evaluated using operation status evaluation values normalized with reference values. In FIG. 15(a), the vertical axis is the operation status evaluation value (=number of users/transport capacity) for the number of elevator users, and the horizontal axis is Building A and Building B. Corresponding to building A, a graph 150 is displayed that shows the evaluation value of the operation status with respect to the number of users of the elevator in building A. Corresponding to building B, a graph 151 showing the evaluation value of the operation status with respect to the number of users of the elevator in building B is displayed. is displayed, and furthermore, an evaluation reference value 152 of the operating state evaluation value is displayed for the graphs 150 and 151. This evaluation reference value 152 is displayed as a broken line as an evaluation reference line that serves as a guide for determining whether or not the elevator operation performance will be affected. Further, in the display area 153, information indicating that the purpose of the building to be evaluated is an office building exclusively owned by one company is displayed.

From the evaluation results shown in FIG. 15(a), the operation condition evaluation value for the number of users of the elevator in building A is larger than that of the elevator in building B, and the operation condition evaluation value exceeds the evaluation standard value. If there is a decline in operational performance, this indicates that the number of passengers is large relative to the transport capacity and may be a factor in the decline in operational performance. On the other hand, in Building B, the operational status evaluation value for the number of users has a margin with respect to the evaluation reference value, indicating that the number of users is unlikely to have an effect on the deterioration of operational performance.

FIG. 15(b) is a schematic diagram showing a first display example in which operation status indicators of elevators in different buildings and corresponding reference values (standard values for normalization) are displayed side by side to evaluate the operation status. be. Although the operation condition index may be expressed as an evaluation value normalized with the reference value as shown in FIG. 15(a), the reference value can be expressed by indicating the operation condition index and the reference value as shown in FIG. You can also compare.

In FIG. 15(b), the vertical axis is the number of people, and the horizontal axis is Building A and Building B. Corresponding to building A, the number of users of the elevator in building A is displayed in a graph 154, and the transportation capacity of the elevator in building A is displayed in a graph 155 as a reference value. Corresponding to building B, the number of users of the elevator in building B is displayed in a graph 156, and the transportation capacity of the elevator in building B is displayed in a graph 157 as a reference value. Further, the operation status evaluation value for the number of users of Building A is displayed in the display area 158 as "0.92", and the operation status evaluation value for the number of users for Building B is displayed as "0.71" in the display area 159. be done. Note that FIG. 15(a) and FIG. 15(b) show the same content.

In FIG. 15(b), the number of users as an operational status index and the transportation capacity as a reference value are displayed separately, so that building A and building B can be compared and evaluated. For example, the number of users is larger in Building B, but the transportation capacity is also larger in Building B, so the operational status evaluation value for the number of users normalized by the transportation capacity is, for Building A = 0.92. Building B = 0.71, which indicates that Building A is larger and that Building A is more demanding in terms of equipment capacity.

At this time, the operation status evaluation value calculation unit 17 determines that the operation data of each elevator input to the operation status index calculation unit 11 and the operation condition detection unit 14, respectively, is the operation data obtained from the elevator to be evaluated among the elevators. , If the operation data is of a comparison elevator installed in a building with different building specifications and operating conditions from the evaluation target elevator, the operation status evaluation value of the evaluation target elevator and the operation status evaluation of the comparison target elevator are used as the operation status evaluation value. Calculate the value. The operation status evaluation unit 20 compares the operation status evaluation value of the elevator to be evaluated calculated by the operation status evaluation value calculation unit 17 with the evaluation reference value calculated by the evaluation standard value calculation unit 19, and also evaluates the operation status of the elevator to be compared. The evaluation value is compared with the evaluation standard value calculated by the evaluation standard value calculation unit 19, and the operating status of the evaluation target elevator and the comparison target elevator is evaluated.

In addition, when connected to an information terminal 22 or a display device having a display screen that displays information indicating the operation status of the elevator, the result output unit 21 outputs the operation status as information used for the evaluation result of the operation status evaluation unit 20. The operation state evaluation value of the evaluation target elevator (graph 150) calculated by the evaluation value calculation unit 17, the operation status evaluation value of the comparison target elevator (graph 151), and the evaluation standard value 152 calculated by the evaluation standard value calculation unit 19 are displayed. Display on screen.

FIG. 16 is a schematic diagram showing a second display example when the elevator operation status is evaluated by the elevator operation status evaluation device according to the present invention. While the first display example in FIG. 15 is an example in which elevators in different buildings are compared, this second display example is an example in which elevators in different banks in the same building are compared.

FIG. 16A is a schematic diagram illustrating a second display example in which operation status indicators of elevators of different banks in the same building are compared and evaluated using operation status evaluation values normalized with reference values. In FIG. 16(a), the vertical axis is the operation status evaluation value for the number of elevator users (=number of users/transport capacity), and the horizontal axis is the low-rise bank and high-rise bank. Corresponding to the low-rise bank, a graph 160 is displayed that shows the evaluation value of the operation status with respect to the number of users of the elevator of the low-rise bank, and corresponding to the high-rise bank, a graph 161 indicating the evaluation value of the operation status with respect to the number of users of the elevator of the high-rise bank is displayed. is displayed, and furthermore, an evaluation reference value 162 of the operating state evaluation value is displayed for the graphs 160 and 161. This evaluation reference value 162 is displayed as a broken line as an evaluation reference line that serves as a guide for determining whether or not the elevator operation performance is affected by a decline. Furthermore, information indicating that the purpose of the building to be evaluated is a multi-tenant office building is displayed in the display area 163.

From FIG. 16(a), it can be seen that the elevators in the high-rise banks have a higher operational status evaluation value for the number of users than the elevators in the low-rise banks, exceeding the evaluation standard value 162. Therefore, in situations where the number of users is large relative to the transportation capacity, it can be determined that elevators in high-rise banks have a stricter equipment capacity than elevators in low-rise banks, and have a greater impact on deterioration of operational performance. .

FIG. 16(b) shows a second display example in which the operation status indicators of elevators of different banks in the same building are displayed side by side with the corresponding reference values (reference values for normalization) to evaluate the operation status. It is a schematic diagram.

In FIG. 16(b), the vertical axis is the number of people, and the horizontal axis is low-rise banks and high-rise banks. Corresponding to the low-rise bank, the number of users of the elevator of the low-rise bank is displayed as a graph 164, and the transport capacity of the elevator of the low-rise bank is displayed as a reference value as a graph 165. Corresponding to the high-rise bank, the number of users of the elevator of the high-rise bank is displayed as a graph 166, and the transport capacity of the elevator of the high-rise bank is displayed as a reference value as a graph 167. Further, the operation status evaluation value for the number of users of the low-rise bank is displayed in the display area 168 as "0.72", and the operation status evaluation value for the number of users of the high-rise bank is displayed as "0.94" in the display area 169. be done.

From FIG. 16(b), it is possible to more specifically compare the operation status of the elevators of each bank, and when there is a decrease in operation performance, it is possible to compare and evaluate the factors of the decrease. For example, a low-rise bank and a high-rise bank both have approximately the same number of users, but the transportation capacity of the high-rise bank is lower, so it can be seen that the high-rise bank is more demanding in terms of equipment capacity than the low-rise bank.

At this time, the operation status evaluation value calculation unit 17 determines that the operation data of each elevator input to the operation status index calculation unit 11 and the operation condition detection unit 14, respectively, is the operation data obtained from the elevator to be evaluated among the elevators. If the operation data is of a comparison target elevator belonging to a different elevator bank from the evaluation target elevator, the operation state evaluation value of the evaluation target elevator and the comparison target elevator are calculated as the operation state evaluation value. The operation status evaluation unit 20 compares the operation status evaluation value of the elevator to be evaluated calculated by the operation status evaluation value calculation unit 17 with the evaluation reference value calculated by the evaluation standard value calculation unit 19, and also evaluates the operation status of the elevator to be compared. The evaluation value is compared with the evaluation standard value calculated by the evaluation standard value calculation unit 19, and the operating status of the evaluation target elevator and the comparison target elevator is evaluated.

In addition, when connected to an information terminal 22 or a display device having a display screen that displays information indicating the operation status of the elevator, the result output unit 21 outputs the operation status as information used for the evaluation result of the operation status evaluation unit 20. The operation state evaluation value of the evaluation target elevator (graph 160) calculated by the evaluation value calculation unit 17, the operation status evaluation value of the comparison target elevator (graph 161), and the evaluation standard value 162 calculated by the evaluation standard value calculation unit 19 are displayed. Display on screen.

FIG. 17 is a schematic diagram showing a third display example when the elevator operating state is evaluated by the elevator operating state evaluation device according to the present invention. The third display example is an example in which the operating conditions of elevators in the same building are changed, whereas the first display example in FIG. 15 is an example in which elevators in different buildings are compared.

FIG. 17A is a schematic diagram illustrating a third display example in which the operation condition index is compared and evaluated using the operation condition evaluation value normalized with the reference value before and after changing the operation conditions of the elevators in the same building. In FIG. 17(a), the vertical axis is the operation status evaluation value for the number of elevator users (=number of users/transport capacity), and the horizontal axis is before (elevator) and after the change in operating conditions (elevator). . A graph 170 showing the operation status evaluation value for the number of users of the elevator before the change in operation conditions is displayed in correspondence with the number of users using the elevator before the change in operation conditions (elevator), and a graph 170 is displayed corresponding to the number of users using the elevator after the change in operation conditions (elevator). A graph 171 showing the operational status evaluation value with respect to the number of people is displayed, and furthermore, an evaluation reference value 172 of the operational status evaluation value is displayed for the graphs 170 and 171. This evaluation reference value 172 is displayed as a broken line as an evaluation reference line that serves as a guide for determining whether or not the elevator operation performance is affected. Further, in the display area 173, information indicating that the purpose of the building to be evaluated is a multi-tenant office building is displayed.

From Figure 17(a), before the operation conditions of the target elevator were changed, the operation status evaluation value for the number of users was high and exceeded the evaluation standard value of 172. There was a possibility that this was causing performance deterioration. On the other hand, after the operational conditions were changed, the operational status evaluation value for the number of users decreased compared to before the operational conditions were changed, and fell below the evaluation standard value of 172, reducing the impact on the deterioration of operational performance and reducing the operational status. It can be seen that the performance has been improved.

Figure 17(b) shows the operation status index and the corresponding reference value (standard value for normalization) displayed side by side before and after the operating conditions of elevators in the same building are changed to evaluate the operation status. FIG. 7 is a schematic diagram showing a third display example.

In FIG. 17(b), the vertical axis is the number of people, and the horizontal axis is before (elevator) and after the change in operating conditions (elevator). Corresponding to before the operation condition change (elevator), the number of users of the elevator before the operation condition change is displayed in a graph 174, and the transportation capacity of the elevator before the operation condition change is displayed as a reference value in a graph 175. Corresponding to after the change (after the operation condition has been changed), the number of users of the elevator after the change in the operation condition is displayed in a graph 176, and the transportation capacity of the elevator after the change in the operation condition is displayed as a reference value in a graph 177. Furthermore, the operation status evaluation value for the number of elevator users before the change in operating conditions is displayed as "0.93" in the display area 178, and the operation status evaluation value for the number of elevator users after the change in operation conditions is displayed as "0.93". 74'' in the display area 179.

From FIG. 17(b), it is possible to more specifically compare the operation status of the elevator before and after the change in operating conditions. In other words, although the number of elevator users remains the same before and after the change in operating conditions, changing the operating conditions has improved transportation capacity, so it can be evaluated that there is more margin in terms of equipment capacity. Furthermore, if a change in operational conditions causes a decrease in operational performance, it becomes possible to compare and evaluate the state of improvement of the factors contributing to the decrease before and after changing the operational conditions.

At this time, the operation state evaluation value calculation unit 17 calculates that the operation data of each elevator input to the operation state index calculation unit 11 and the operation condition detection unit 14 respectively are the operation data before the operation conditions are changed and the operation conditions If the operation data is after the change, the operation condition evaluation value before the operation condition change and the operation condition evaluation value after the operation condition change are calculated as the operation condition evaluation value. The operation condition evaluation section 20 compares the operation condition evaluation value before the operation condition change calculated by the operation condition evaluation value calculation section 17 with the evaluation reference value calculated by the evaluation reference value calculation section 19, and compares the operation condition evaluation value calculated by the operation condition evaluation value calculation section 17 with the evaluation reference value calculated by the evaluation reference value calculation section 19. The operation condition evaluation value and the evaluation reference value calculated by the evaluation reference value calculation unit 19 are compared to evaluate the operation condition of each elevator before and after the operation condition is changed.

In addition, when the result output unit 21 is connected to an information terminal 22 or a display device having a display screen that displays information on the operation status of the elevator, the result output unit 21 outputs the operation status evaluation as information used for the evaluation result of the operation status evaluation unit 20. The operation condition evaluation value before the operation condition change (graph 170) calculated by the value calculation unit 17, the operation condition evaluation value after the operation condition change (graph 171), and the evaluation reference value 172 calculated by the evaluation reference value calculation unit 19. Display on the display screen.

FIG. 18 is a schematic diagram showing a fourth display example when the elevator operating state is evaluated by the elevator operating state evaluation device according to the present invention. While the first display example in FIG. 15 is an example of comparing the operation status evaluation values for the number of users of elevators in different buildings, the fourth display example is an example of comparing the operation performance of elevators in different buildings. This is a combination of examples that compare factors related to the deterioration of elevator operating performance in different buildings. According to the fourth display example, when the elevator performance has deteriorated, it is possible to determine by comparative evaluation the index related to the item that is the cause of the deterioration.

In FIG. 18, a display area 180 of the information terminal 22 is composed of a display area 181 for displaying operational status indicators related to operational performance, and a display area 182 for displaying the status of factors related to deterioration of operational performance. be done.

In the display area 181, a graph 183 showing the average waiting time of building A and a graph 184 showing the average waiting time of building B are graphs for displaying operation status indicators related to operation performance (for example, average waiting time). is displayed. Furthermore, an evaluation level 185, which is a measure of the deterioration of operational performance, is displayed for the graphs 183 and 184. From the information displayed in the display area 181, it can be confirmed whether or not the operating performance of the elevator has deteriorated. For example, in the example displayed in the display area 181, the graph 183 of building A exceeds the evaluation level 185, so it can be seen that the elevators in building A are experiencing a decline in operational performance.

In the display area 182, a graph 186 showing the operation status evaluation value for the number of users of the elevator in Building A and a graph 186 showing the operation status for the number of users of the elevator in Building B are graphs for displaying the status of factors related to the decline in operation performance. A graph 187 showing the evaluation value is displayed. Furthermore, an evaluation reference value 188 is displayed for the graphs 186 and 187, which is an evaluation reference line for determining whether or not the graphs 186 and 187 have an effect on the deterioration of operation performance.

In addition, in the display area 182, as graphs for displaying the status of factors related to the deterioration of operational performance, a graph 189 showing the operational status evaluation value for the average one-round time of the elevator in Building A and an average of the elevator in Building B are displayed. A graph 190 showing the operating state evaluation value for one round time is displayed. Furthermore, an evaluation reference value 191 is displayed on the graphs 189 and 190, which is an evaluation reference line for determining whether or not the graphs 189 and 190 have an effect on the deterioration of operation performance.

From the information displayed in the display area 182, as an evaluation result of the elevator in Building A, the operation status evaluation value for the number of users and the operation status evaluation value for the average one round time are both evaluation reference values that affect the deterioration of operation performance. It is possible that both of these factors are contributing factors to the decline in service.

Based on these evaluation results, the evaluation results for the factors contributing to the decline in operational performance were: ``Due to the large number of people using the elevator, the number of stops at each floor may have increased, resulting in a longer one-turn time.'' The factors are determined. A message for this cause is displayed in the display area 192.

In the display area 180, graphs 183 and 184 showing operation status indicators (average waiting time) related to operation performance, and graphs 186, 187, 189, and 190 indicating operation status evaluation values that are factors related to deterioration of operation performance are displayed. By displaying these in combination, it becomes possible to determine the operating condition of the elevator being evaluated and, if the operating condition is not good, the cause of the problem and lead to improvements.

According to this embodiment, it is possible to objectively evaluate the quality of the operating condition of the elevator. At this time, by comparing each elevator using the operation status evaluation value obtained from the operation performance value indicating the operation status index (operation status index) of the elevator and its reference value (operation status reference value), each elevator is can be compared and evaluated using the same scale. That is, each elevator can be comparatively evaluated using the operating state evaluation value as a criterion. As a result, the operational status of elevators with different equipment specifications and operating conditions can be compared and evaluated using the same scale, using the operational status evaluation value.
