Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an energy-saving evaluation system for an elevator.
[0002]
[Prior art]
The most common rope type elevator among elevators is operated by electric energy using a motor as a power. For this reason, energy saving has been steadily promoted in elevators as energy saving momentum has recently increased.
[0003]
Conventional technologies related to elevators, energy saving, their services, and evaluation systems can be classified into the following four categories.
[0004]
1) Energy saving technology for elevators
2) Energy saving services in general industrial systems
3) Calculation system for elevator maintenance fees
4) Evaluation system for elevator operation control
Hereinafter, each will be described.
[0005]
1) Energy saving technology for elevators
Recently, attention has been paid to energy saving technologies using batteries. In a standard-class elevator (also called a standard-type elevator), the motor consumes the regenerative power generated during regenerative operation (operating as a generator) by converting it into heat with a resistor. Japanese Patent Application Laid-Open No. 2000-2000 discloses a method of returning to a motor during power running operation to reuse
No. 255918, Japanese Unexamined Patent Application Publication No. 2001-187676, and a document of the Institute of Electrical Engineers of Japan, JSPE-27-5 (titled "Development of an energy-saving elevator using a regenerative power storage system").
[0006]
2) Energy saving services in general industrial systems
An example of an energy saving service for a facility equipped with a motor such as a factory is disclosed in Japanese Patent Application Laid-Open No. 2001-155083. In this example, the user who wants to save energy does not need to make an initial investment, and the energy saving service provider installs or improves the equipment and provides the benefits according to the degree of achievement of energy saving (saving electricity rate). A service form that is distributed between a provider and a user is presented.
[0007]
3) Calculation system for elevator maintenance fees
Japanese Patent Application Laid-Open No. 2001-256380 discloses an example of a system that calculates an elevator maintenance fee in accordance with a customer's use situation and a customer's desired guarantee. This system monitors the elevator usage status of customers and sets maintenance fees according to usage status during that period, or calculates individual maintenance fees according to options selected by the customer. , A contract terminal, a charge calculation unit, and an operation data collection unit constitute a system.
[0008]
4) Evaluation system for elevator operation control
An example of an evaluation system for elevator operation control is presented in Proceeding of ELEVCON 2001 (ELEVATOR TECHNOLOGY 11) p113-p121 under the heading 'Elevator planning and analysis the Web'. This technology is an evaluation tool for elevator installation planning and layout planning. Specifically, when a user inputs building information on the Internet web screen, numerical analysis of the operation is performed, and the operation performance such as round-trip time and waiting time is output. The required number of elevators, speed, etc. can be determined.
[0009]
[Problems to be solved by the invention]
As described above, energy-saving technologies for elevators, various services related to elevators, and energy-saving services for general industrial equipment have already been considered. However, when trying to implement a business or service that actually saves energy in elevators, there are problems. Occurs. The problems of each of the above-mentioned prior arts 1) to 4) are summarized below.
[0010]
1) Issues in implementing energy-saving technologies for elevators
In an energy saving system in which regenerated electric power is reused by storage or the like, the energy saving effect largely depends on the use condition of the elevator. In addition, the specifications of batteries and the like necessary for implementing energy saving largely depend on the use condition of the elevator. For example, in the case of an apartment house (condominium, etc.) that is basically used only by residents and a department store that is used almost frequently by outside customers during the day, even if elevators with the same specifications are used, the electricity Are completely different, and therefore the energy saving effect obtained and the required device specifications are also different.
[0011]
Therefore, even if the owner of the building intends to save energy for the elevator, at that time (at the time of examination before introduction), it is not known how much energy saving effect can be obtained, and it must be determined by the specifications of the equipment to be introduced. I do not know the investment. Even if an inquiry is made to the manufacturer or service provider of the energy saving device, it is still difficult to obtain a specific answer because the use status of the elevator is not known. In other words, at the time of the examination before the introduction, the building owners do not know how much investment is required, how much energy saving effect is obtained, and how cost-effective it is. Will not be able to step on.
[0012]
2) Energy saving services in general industrial systems
In the service method disclosed in the prior art, the user and the service provider enjoy the energy saving effect by making initial investment free of charge and allocating the merit according to the degree of achievement of energy saving (saving electricity rate). It is aimed at doing. However, in the case of elevators, since the amount of power consumption is basically small, even if the power can be saved, the amount of power is small, and it is difficult to recover the equipment provided by the service provider at the saved power rate. . In particular, when a large energy-saving effect is aimed at, the above-described method of reusing regenerative power is the most effective, but in this case, the cost of introducing equipment such as batteries also increases. In other words, when the above-described service is performed by the elevator, it is difficult to determine the cost-effectiveness because the amount of power consumption is small, and it is difficult for both the user and the service provider to take the service.
[0013]
3) Calculation system for elevator maintenance fees
The maintenance fee calculation system disclosed in the related art can monitor the usage status of an elevator and calculate a maintenance fee according to the usage status. However, when applied to the calculation of the energy-saving effect, especially when calculating the energy-saving effect by reusing the most effective regenerative power, the characteristics of the energy-saving device such as a battery and the electricity rate system must be taken into account Can not be evaluated. For example, the energy saving effect varies greatly depending on the battery capacity and how the battery is used. Also, in consideration of the electricity rate system, it is difficult to evaluate, for example, making the electricity rate lower.
[0014]
4) Evaluation system for elevator operation control
In operation simulation evaluation, it is difficult to satisfy the demands of users who want to save energy. As in the case of the above 3), it is necessary to take into consideration the characteristics of the energy saving device such as a battery and the electricity rate system. Further, in the disclosed conventional system, input items such as elevator speed, acceleration, door opening / closing time, and the like, which can be understood only by persons having expert knowledge of the elevator, are set. Is not a system that can be easily evaluated independently.
[0015]
As described above, the problems in realizing the energy saving of an elevator as a business or service can be summarized as follows.
[0016]
1) The energy-saving effect or cost-effectiveness of an energy-saving device such as a battery cannot be evaluated in advance (when considering before introducing the device).
[0017]
2) The energy saving effect corresponding to the usage conditions of the elevator user cannot be evaluated.
[0018]
3) Input items for the evaluation system are complicated.
[0019]
4) Electricity rate system cannot be considered.
[0020]
5) Since the power consumption of the elevator is small, it is difficult to establish a service in which the initial investment is reduced to zero and the electricity rate saved by energy saving is distributed between the user and the service provider.
[0021]
The present invention has been made in consideration of the above problems, and provides an energy saving evaluation system for a lift which is suitable for making energy saving of the lift a business or service.
[0022]
[Means for Solving the Problems]
In the energy-saving evaluation system for elevators according to the present invention, when information on the elevator and information on the building in which the elevator is installed is input at the terminal, the current power consumption or electricity cost of the elevator, and after the introduction of the energy-saving device, Power consumption or electricity bill is output. Alternatively, when the terminal inputs authentication information indicating that the customer is a maintenance contract customer of the elevator, the current power consumption or electricity cost of the elevator and the power consumption or electricity cost after the introduction of the energy saving device are output. . Therefore, a customer such as an elevator user or a building owner who uses the energy saving device can easily confirm the effect of introducing the energy saving device.
[0023]
Further, a more specific configuration of the energy saving evaluation system for an elevator according to the present invention is as follows. That is, a means for inputting information about the elevator and information about the building in which the elevator is installed, and a means for estimating the operation information of the elevator and the specification of the elevator from these information, and from the estimated operation information and specification, There is provided a means for calculating the current power consumption and the power consumption when the energy saving device is used. Further, an output means for outputting the obtained result, that is, each power consumption, is provided. Instead of entering information on elevators and buildings, enter authentication information indicating that the customer is a maintenance contract customer for the elevators.When the customer is authenticated as a maintenance contract customer by the authentication information, operation information is obtained from the information on elevators and buildings. Alternatively, the specifications of the elevator may be estimated. In this case, it is preferable that information on the elevator and the building is stored in the database in association with the maintenance contract customer. Alternatively, the actually measured operation data of the elevator and the specification data of the elevator may be input.
[0024]
By providing means for estimating the operating state of the elevator and the specifications of the elevator from information on the elevator and the building, it is possible to estimate the operation pattern of the elevator and the specifications of the elevator suitable for the building from simple input items. Therefore, by using these estimated data, it is possible to evaluate the energy saving effect according to the use condition of the elevator in the building.
[0025]
The energy-saving evaluation system for an elevator according to the present invention can be used by a customer via a network. The system configuration at that time is a means for displaying a screen for inputting information about the elevator and the building to the terminal via the network, and receiving the information input using the screen via the network, and receiving the received information. Means for estimating operation information and specifications of the elevator based on the Furthermore, based on the estimated operation information and specifications, means for calculating the current power consumption and the power consumption when the energy saving device is used, and means for displaying the obtained result on a terminal via a network Is provided. As described above, the user inputs authentication information indicating that the customer is a maintenance contract customer of the elevator and, based on the authentication data information, refers to the information on the user's elevator stored in the database, and The power consumption and the power consumption when the energy saving device is used may be obtained. According to such a system configuration, a business or service related to energy saving of an elevator using a network is enabled.
[0026]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an energy saving evaluation system for an elevator according to an embodiment of the present invention.
[0027]
This evaluation system is roughly composed of a data input unit, an estimation unit, an analysis unit, and a result output unit. The outline of the operation is as follows. First, information about a user's building and elevator is input in a data input unit, and information necessary for analysis (for example, an elevator operation pattern and elevator specifications) is estimated from the input data in an estimating unit. Next, the analysis unit calculates the energy saving effect by using a battery (corresponding to a chargeable / dischargeable secondary battery) or regenerative power using a regenerative converter. Then, the result output unit displays the energy saving effect obtained by the analysis unit, the installation cost of the device, and the like. As a result, building owners, elevator users, and the like, at the time of study before introducing energy-saving devices, can evaluate the approximate energy-saving effect according to the use status of elevators in the building, the cost required for introduction, and the like. it can. Here, as an energy saving measure using a battery, there are, for example, 1) a load leveling method, 2) a peak cut method, and 3) a regenerative power storage method. 1) is intended to significantly reduce contract power by lowering input power (or input current) on the power supply side to a certain value or less. 2) is to partially reduce the power peak, and to reduce the contracted power as in 1), but the amount of reduction is smaller than in 1), but the battery capacity is small. The method 3) is a method in which regenerative electric power is stored in a battery and returned from the battery to the motor during power running operation. The regenerative power is stored in a battery and reused. The effect of reducing the contracted power is smaller than 2), but the methods 1) to 3) can be combined. For example, if an appropriate battery is used for the load leveling method and the peak cut method, it is also possible to store power during regeneration using the battery. Also, in the regenerative power storage method, it is possible to cut the power peak by applying the stored regenerative power only to the peak cut.
[0028]
The features of the energy saving evaluation system shown in FIG. 1 are as follows.
・ Evaluate the energy saving effect of the target elevator on the terminal before introducing the device.
-It is possible to evaluate the energy saving effect for energy saving devices that reuse regenerative power such as batteries.
・ Evaluate the energy saving effect corresponding to the usage conditions of the target elevator.
-With simple input items, building owners and elevator users can independently evaluate.
・ Evaluation can be made in consideration of the electricity tariff system.
[0029]
Hereinafter, the operation of the energy saving evaluation system shown in FIG. 1 will be described in more detail along the flow.
[0030]
1) Data input section
Information on the building and information on the specifications of the elevator are input by the evaluation data input means 1 and the energy saving menu selection means 2. In the evaluation data input means 1, the input items are set so that ordinary people, such as building owners and elevator users, can easily evaluate by themselves. Details of the input items will be described later. The energy-saving menu selection means 2 can select an energy-saving method (menu) according to the type of building (the use status of the elevator). Since the contents of this energy saving method that can be selected vary depending on the type of building (the use status of the elevator), a selection menu according to the type of building is displayed after inputting the evaluation data input means 1.
[0031]
The service purchase mode selection means 9 can select a purchase mode when purchasing a service including an energy saving device. This allows the building owner or elevator user to select the desired form of service.
[0032]
2) Estimator
Based on the input data obtained by the evaluation data input unit 1, the elevator operation pattern estimating unit 3 estimates the target elevator operation pattern (for example, the daily elevator operation pattern) and determines the elevator model and specifications. The data estimating means 4 estimates the model and specification of the target elevator. These data will be data for analyzing the energy saving effect in the next analysis unit. For example, the energy saving effect and the energy saving method (specifications of the energy saving device, etc.) are significantly different between the case where the device is frequently used throughout the day and the case where the device is frequently used only at a specific time. Thus, by having means for estimating the elevator operation pattern and the elevator model and specification from the input data, it becomes possible to analyze the energy saving effect according to the use condition and the model and specification of the target elevator. .
[0033]
The elevator operation pattern estimating means 3 selects an operation pattern to be estimated from the elevator operation pattern database 5. The elevator model / specification data estimating means 4 selects a model and specifications to be estimated from an elevator model database. By using a database in which data is stored in advance, estimation can be performed at high speed and with high accuracy.
[0034]
3) Analysis section
In the energy saving effect analysis means 10, the target is obtained from the target elevator operation pattern estimated by the elevator operation pattern estimation means 3 and the target elevator model and specification estimated by the elevator model / specification data estimation means 4. Analyze the current power profile for the elevator and the power profile after the introduction of the energy saving device. Here, the power profile indicates a change in power with respect to each time. Specifically, a graph in which the horizontal axis represents time and the vertical axis represents power consumption is calculated in a 24-hour range. By calculating the difference between the current power profile and the power profile after the introduction of the energy saving device, a power profile corresponding to the energy saving effect can be obtained.
[0035]
In order to obtain the power profile after the introduction of the energy saving device, an analysis including the operation of the energy saving device is required. The energy-saving effect analysis means 10 selects a necessary energy-saving device (battery or regenerative converter) from the result of the energy-saving menu selection means 2 and, if it is a battery, retrieves the corresponding model from the battery model database 7 and Is a regenerative converter, the corresponding model is extracted from the regenerative converter model database 8 and is analyzed. In this way, the energy saving effect of the storage battery or the regenerative converter to which the three energy saving methods of the load leveling method, the peak cut method, and the regenerative power storage method can be applied can be analyzed in consideration of the specifications of the device.
[0036]
The electricity cost evaluation unit 11 calculates and obtains a power rate in each case from the current power profile and the power profile after the introduction of the energy saving device. Here, in calculating the power rate, the power rate calculation data stored in the power rate database 12 is used. According to such a method, it is possible to calculate the current power rate and the power rate after the introduction of the energy saving device according to the power rate system.
[0037]
The introduction cost evaluation means 13 calculates the equipment cost from the required specifications (for example, the capacity) of the energy saving apparatus, and calculates the required introduction cost based on the service form selected by the service purchase form selection means 9.
[0038]
4) Result output section
The evaluation result data output means 14 outputs, as evaluation results, the energy saving effect of the unit of power (for example, kWh) obtained by the energy saving effect analyzing means 10 and the energy saving effect at the electricity rate obtained by the electricity cost evaluation means 11. From this result, the building owner, the elevator user, and the like can estimate the approximate energy saving effect for the target elevator in units of electricity rate, electric power, and the like.
[0039]
The introduction cost output unit 15 outputs the introduction cost calculated by the introduction cost evaluation unit 13 based on the service form. From this result, the owner of the building, the user of the elevator, and the like can know the introduction cost necessary for obtaining the energy saving effect indicated by the evaluation result data output means 14 for the target elevator.
[0040]
Further, the owner of the building, the user of the elevator, and the like can compare the result of the introduction cost output means 15 with the result of the evaluation result data output means 14 to estimate the approximate cost of saving energy in the target elevator. You can know the effect.
[0041]
According to the flow described above, the energy-saving evaluation system for an elevator shown in FIG. 1 uses the energy-saving effect (approximate value) according to the use status and the model / specification of the elevator in the examination stage before introducing the energy-saving device, and the cost required for the introduction (Approximate value) can be evaluated.
[0042]
FIG. 15 shows a series of flows from the energy saving evaluation by the elevator energy saving evaluation system of FIG. 1 to the introduction of the energy saving device. First, an energy saving evaluation system for an elevator is accessed from a terminal such as a personal computer or a portable terminal, and a simple energy saving effect evaluation is performed by inputting the terminal (S110). If the evaluation result is less than the desired energy saving effect, the process ends. If the evaluation result is more than the desired energy saving effect, the energy saving service provider conducts actual measurement of the elevator operation pattern and performs a more detailed energy saving evaluation ( S111, S112). If the result of the detailed evaluation is less than the required energy saving effect, the process ends. If the result of the detailed evaluation is more than the required energy saving effect, an energy saving device (battery or regenerative converter) is introduced (S113, S114). Then, the energy saving service provider periodically checks whether the desired energy saving effect has been obtained even after the introduction of the device, and reports it to the energy saving device introducer (S115). In this way, before the introduction of the energy-saving device, a simple preliminary evaluation using the energy-saving evaluation system of the elevator of FIG. 1 and a detailed evaluation step by actual measurement are performed. The device can be introduced after predicting the energy saving effect.
[0043]
FIG. 2 shows another embodiment of an energy saving evaluation system for an elevator. In the present embodiment, it is assumed that a system user (for example, a building owner or an elevator user) has a maintenance contract with an elevator maintenance company or service company that provides this evaluation system. In FIG. 2, the same reference numerals as those in FIG. 1 represent the same elements. The difference from FIG. 1 is in the data input unit, in which the elevator information of the system user is input by the maintenance customer authentication data input means 16 and the elevator information database 17 for the maintenance customer. That is, if the system user has a maintenance contract with the elevator maintenance company that provides this evaluation system, the information on the elevator is stored as a database. Then, which maintenance customer is identified by authentication, the customer information is referred to from the elevator information database 17 for the maintenance customer when the customer is identified as the maintenance customer. By doing so, it is possible to save the user of the system from inputting the input items, and to obtain more accurate information on the target elevator.
[0044]
FIG. 3 shows another embodiment of an energy saving evaluation system for an elevator. In FIG. 3, components having the same reference numerals as those in FIG. 1 represent the same elements. This embodiment shows an elevator energy saving evaluation system applied in the detailed evaluation (S112) by actually measuring the operation pattern of the elevator in the flow from evaluation to purchase in the energy saving of the elevator shown in FIG. The difference from FIG. 1 is in the data input unit, in which the elevator operation pattern actual measurement data 18 is directly input. The elevator model and specification data input means 201 also directly inputs the elevator model and specification. As described above, by allowing the energy saving evaluation system to directly handle the actual measurement data, it is possible to execute an analysis that is more suitable for an actual situation, and it is possible to increase the accuracy of evaluating the energy saving effect. Again, following the flow shown in FIG. 15, the energy saving evaluation system of FIG. 1 or FIG. 2 is applied to the simple energy saving effect evaluation (S110) by terminal input, and the detailed energy saving effect is obtained by actually measuring the elevator operation pattern. The energy saving evaluation system of FIG. 3 is applied to the evaluation (S112). As described above, by performing the two-stage evaluation of simple and detailed, a building owner or an elevator user having an elevator with a low possibility of energy saving effect can know the result at an early stage, and can also evaluate the energy saving effect. Building owners or elevator users with high-probability elevators can know the effect with greater accuracy.
[0045]
Next, details of each element in the elevator energy saving evaluation system shown in FIG. 1 or 2 will be described.
[0046]
(1) Details of data input section
FIG. 4 shows an example of an input screen in the evaluation data input means 1 shown in FIG. The screen in FIG. 4 assumes a case in which a system user (for example, a building owner or an elevator user) has not entered into a maintenance contract with an elevator maintenance company or service company that provides this evaluation system. .
[0047]
In FIG. 4, the evaluation data input screen 19 is large and is composed of an elevator use condition input screen 20 and an elevator detailed condition input screen 27.
[0048]
The elevator use condition input screen 20 is a screen for inputting information on the use state of the elevator, and is an item 21 for inputting the building where the elevator is installed, an item 22 for inputting the number of floors of the building, and inputting the number of households of the building. 23, an item 24 for inputting the number of residents per floor of the building, an item 25 for inputting the number of elevators, and an item 26 for inputting the year of introduction of the elevator. If the person who uses or owns the elevator, those who do not have expert knowledge of the elevator can roughly find these input items, and they are simple input items so that even ordinary people can operate them. . Then, by the function of the estimating unit described later, a mechanism for estimating data necessary for actual analysis from these simple input data is provided. From these data, the elevator operation pattern, model and specifications are estimated.
[0049]
The elevator detailed condition input screen 27 includes an item 28 for inputting the number of elevators and an item 29 for inputting the loaded weight of the elevator. These items are useful information for determining the specifications of the target elevator. Also, since these items are usually described in the elevator car, the entry can be made relatively easily by the elevator owner or the elevator user.
[0050]
After all items have been input, a selection is made in item 206 as to whether or not to execute the energy saving effect estimation calculation.
[0051]
FIG. 5 shows a state of an input menu for an item 21 for inputting a building where an elevator is installed on the evaluation data input screen 19 of FIG. 4, and includes "apartment", "office building", and "hotel". , "Hospital", "school", "tenant building", and "department / shopping center", the corresponding item can be selected. By using the selection menu in this way, the user of this evaluation system can execute the input smoothly. Further, since the input contents of the item 21 for inputting the building in which the elevator is installed is an important element for determining the operation pattern of the elevator, there is no input omission, unidentifiable mistake, etc. by specifying the input menu in advance. I can do it. In addition, since an operation pattern corresponding to each item of the input menu can be prepared in advance, analysis can be efficiently performed.
[0052]
FIG. 6 shows an example of an input screen in the maintenance customer authentication data input means 16 shown in FIG. That is, the screen in FIG. 6 assumes a case where a system user (for example, a building owner or an elevator user) has a maintenance contract with an elevator maintenance company or service company that provides this evaluation system. I have. In FIG. 6, the evaluation data input screen 31 can be divided into a maintenance contract customer input screen 32 and a customer confirmation screen 35. The maintenance contract customer input screen 32 includes an item 33 for inputting a contract number and an item 34 for inputting a password for authenticating the customer. If the customer is authenticated by the entered contract number and password, the name of the customer who has been authenticated is displayed in an item 36 for displaying the customer name on the customer confirmation screen 35. In this way, if the system user has a maintenance contract with an elevator maintenance company or service company that provides this evaluation system, a simpler input method can be used. Further, as shown in FIG. 2, since the data of the authenticated customer is retrieved from the database, more accurate elevator information can be retrieved.
[0053]
FIG. 21 shows a flowchart for setting a menu to be selected in the energy saving menu selection means 2 shown in FIG. 1 or FIG. The energy saving menu selection means 2 presents an energy saving menu corresponding to the type of building determined in the preceding stage.
[0054]
First, it is determined whether or not the building type is a condominium building (S150). If the building is not a condominium building, it is further inquired whether or not it is desired to continue elevator operation during a power failure (S151). If it is desired to continue the operation at the time of power failure, the device to be introduced is a relatively small-capacity battery system, and the control method is the storage and reuse of regenerative power (S152). If it is not desired to continue the operation at the time of the power failure, the device to be introduced is a regenerative converter, and the control method is power regeneration of regenerative power (S153). If the building type is a condominium building, whether to emphasize saving on electricity costs (apply the load leveling method or peak cut method using batteries) or save energy by reusing regenerative power (regeneration using batteries) Inquiry about the application of the power storage method) (S154). Here, in the former case, the battery capacity is increased, so that the cost for introducing the device is increased. In the latter case, since the battery capacity is small, the cost for introducing the device is reduced. In summary, when saving on electricity bills is important, the equipment to be introduced will be a large-capacity battery system, and the control system will be a load leveling scheme or a peak cut scheme, aiming to save electricity bills by reducing contract power. When energy saving is emphasized, the device to be introduced is a battery system with a relatively small capacity, and the control method is reuse by storage of regenerative power.
[0055]
Here, when the building type is a condominium, the system that supplies power to the elevator is configured as a system with the elevator as the main load, independent of the other systems, so the load leveling method using batteries By reducing the peak power of the elevator by the peak cut method, the contract power for the system can be reduced. In this case, the elevator has a characteristic that the amount of electric power used is small but the peak electric power is large. Therefore, there is a possibility that the electric power fee can be greatly reduced as compared with other methods. However, in order to lower the peak power, it is necessary to use a large-capacity battery, charge the system for a long time with small power, and supply power to the elevator from the battery. There is also the aspect that the introduction cost increases. Based on this, it is first determined whether the building type is a condominium (S150), and in the case of a condominium, whether to further focus on saving on electricity bills, that is, contracts using a load leveling method using a battery or a peak cut method An inquiry is made as to whether to aim at power reduction or only energy saving by reusing regenerated power (S154).
[0056]
In the case of buildings other than condominiums, other large-capacity loads are connected to the same grid, so even if the peak power of the elevator is reduced, a reduction in contracted power cannot be expected, and energy can be saved by reusing regenerative power. Only implementation. However, in this case, there is a choice between returning the regenerative power to the power supply side by the regenerative converter or storing it in the battery and reusing it.In the latter case, the cost is increased, but the power is supplied from the battery even during a power failure Thus, the elevator can be operated for a short time. For this reason, an inquiry is made as to whether it is desired to continue the operation of the elevator at the time of the power failure (S151). In this way, each energy-saving menu can be set according to the type of building, and what kind of added value is desired can be selected, so that a wide range of energy-saving methods can be selected according to the elevator situation. .
[0057]
FIG. 9 shows an example of an input screen for the energy saving menu selection means 2 in the energy saving evaluation system for an elevator shown in FIG. 1 or FIG. FIG. 9 corresponds to the branch (S151) of the flowchart shown in FIG. 21 for inquiring whether or not the continuation of the elevator operation is desired at the time of a power failure. In FIG. 9, the energy saving menu selection screen 42 is intended for elevators of buildings other than condominiums, and includes a screen 43 for selecting whether or not to want the elevator to continue operating even during a power outage. I have. This screen also has an explanation section for the difference between the case where the request is made and the case where the request is not made. After the selection, one of them is selected in an item 44 for selecting whether or not to execute the energy saving effect estimation calculation.
[0058]
FIG. 10 shows an example of an input screen for the energy saving menu selection means 2 in the energy saving evaluation system for an elevator shown in FIG. 1 or FIG. FIG. 9 corresponds to the branch (S154) of the flowchart shown in FIG. 21 for inquiring whether to emphasize saving on electricity costs or energy saving. Figure
In FIG. 10, the energy saving menu selection screen 45 is for an elevator of a condominium building, and includes a screen 46 for selecting whether to give priority to reducing the electricity bill or to save power. The screen also has an explanation section for each case. After the selection, an item 47 for selecting whether or not to execute the energy saving effect estimation calculation is selected.
[0059]
FIG. 11 shows an example of a selection screen corresponding to the service purchase mode selection means 9 in the elevator energy saving evaluation system shown in FIG. 1 or FIG. In FIG. 11, the service purchase mode selection screen 48 assumes that the system user has not entered into a maintenance contract with an elevator maintenance company or service company that provides this evaluation system. In this case, as shown in the screen 49, the purchase form is
A) Energy-saving equipment will be introduced free of charge, but a maintenance contract is signed.
B) Purchased as a leased item
You can choose either. The details of each purchase form will be described later in the description of the service.
[0060]
FIG. 12 shows an example of a selection screen corresponding to the service purchase mode selection means 9 in the elevator energy saving evaluation system shown in FIG. In FIG. 12, the service purchase mode selection screen 51 assumes that the system user has a maintenance contract with an elevator maintenance company or service company that provides this evaluation system. In this case, the purchase mode is only the energy saving option in the maintenance menu. The details of this purchase mode will be described later in the description of the service.
[0061]
As shown in FIG. 11 and FIG. 12, by providing a purchase mode selection screen that is divided depending on whether or not a maintenance contract is concluded, the user of the system selects a more appropriate purchase mode that meets the conditions. can do.
[0062]
(2) Details of the estimation unit
FIG. 22 shows details of the elevator operation pattern estimating means 3 and the elevator operation pattern database 5 in the elevator energy saving evaluation apparatus shown in FIG. 1 or FIG. FIG. 22A shows an example of the contents of the elevator operation pattern database. In this database, a 24-hour elevator operation model corresponding to the classification is stored in each item classified by the type of building and the total number of floors of the building (the contents of each 24-hour operation model are as follows). Is different). Here, the classification of the type of building is set so as to match the content displayed in the input menu 30 for the item 21 for inputting the building where the elevator is installed as shown in FIG. For example, classifications such as “apartment”, “office building”, “hotel”, “hospital”, “school”, “tenant building”, and “department shopping center” can be considered.
[0063]
FIG. 22 (b) shows details of the 24-hour elevator operation model shown in FIG. 22 (a). Here, the case where the total number of floors of the building is 5 is shown. The elevator operation model for 24 hours shown in FIG. 22B is composed of four components: the time at which the elevator operates, the driving direction, the number of moving floors, and the occupancy rate. For example, the operation described in the first row of FIG. 22B indicates that an operation having a floor occupancy of 0.1 occurred at 7:00:03 am on the fifth floor in the ascending direction. In this way, for each elevator operation, data accurately defined by the four components of (time, driving direction, number of moving floors, and occupancy) is stored for 24 hours. Further, such 24-hour data is prepared differently for each item shown in FIG. The figure
The occupancy rate in the 24-hour elevator operation model shown in FIG. 22 (b) represents the ratio of the elevator to the occupancy.
[0064]
FIG. 22 (c) shows the processing contents of the elevator operation pattern estimating means 3 in the elevator energy saving evaluation apparatus shown in FIG. 1 or FIG. Here, the data of the building type, the total number of floors of the building, and the number of passengers in the data input by the evaluation data input means 1 of FIG. 1 are used. First, a corresponding 24-hour operation model is extracted from the elevator operation pattern database 118 (the same as the elevator operation pattern database 5 of FIG. 1 or 2) based on the data of the building type and the total number of floors of the building (FIG. 1). 117). This corresponds to the process of specifying the building type and the total number of floors and extracting the corresponding operation model from the elevator operation pattern database shown in FIG. Next, each element of the obtained boarding rate of the 24-hour operation model is multiplied by the number of boarding passengers and converted to the number of boarding passengers. As a result, it is possible to obtain a 24-hour operation model defined by four components (time, driving direction, number of moving floors, number of passengers) for each operation of the elevator.
[0065]
In this way, a more accurate 24-hour elevator operation model corresponding to the type of building in which the target elevator is installed, the total number of floors, and the number of passengers in the elevator can be obtained. That is, it is possible to obtain an elevator operation model that matches the usage status of the target elevator. Also figure
By using the database organized as shown in FIG. 22A, the processing time required to obtain an operation model can be sufficiently reduced.
[0066]
FIG. 23 shows the details of the processing of the elevator model / specification data estimating means 4 in the elevator energy saving evaluation apparatus shown in FIG. 1 or 2. Here, data on the number of years of use of the elevator, the total number of floors in the building, and the number of passengers in the elevator in the data input by the evaluation data input means 1 in FIG. 1 are used. First, in the elevator model / specification data estimating means (S160), the elevator model / specification database S161 (elevator type database in FIG. 6) and specify the target elevator model and specifications. Next, based on the specified model and specification, it is confirmed whether or not the model and specification are within the target range of the energy saving evaluation (S162). If your review does not qualify,
A message “the elevator is out of the evaluation target” is output and the processing is stopped. For example, a high-speed elevator in which the elevator is already equipped with a regenerative converter as a standard (an elevator having a higher speed than a standard or standard type elevator) is out of scope. If the model and specification are within the target range, use the specification data for the next analysis. FIG. 23 shows an example of the finally extracted specification data (S163). In this example, data of the rated speed, the rated output of the motor, the roping, the sheave diameter, and the converter efficiency coefficient are set as the specification data of the elevator. These data are important data in calculating the power consumption of the elevator. As described above, since the process of estimating the elevator specification data necessary for calculating the power consumption from the simple input data such as the number of years of use of the elevator, the total number of floors in the building, and the number of passengers in the elevator is performed, Despite the input, a more accurate analysis of the energy saving effect can be executed. In addition, by including a process of confirming whether or not the target elevator is within the energy saving target range, it is possible to remove in advance the elevators that are out of the target.
[0067]
(3) Details of analysis unit
FIG. 20 shows an example of the processing content of the energy saving effect analysis means 10 shown in FIG. 1 or FIG. The energy-saving effect analysis means analyzes a 24-hour power profile before the introduction of the energy-saving device (a data series expressing the aspect of power consumption using the time axis as a parameter) and a 24-hour power profile after the introduction of the energy-saving device. By comparing the two, the energy saving effect before and after the introduction of the energy saving device can be evaluated.
[0068]
20, the input information includes an elevator 24-hour operation model obtained from the elevator operation pattern estimating means 3 shown in FIG. 1 or FIG. 2 and the elevator model / type of the elevator shown in FIG. 1 or FIG. The elevator model and specification data obtained from the specification data estimation means 4 are obtained. First, a 24-hour speed profile (a data series in which the operation of the elevator is represented by speed using time as a parameter) is calculated by the 24-hour speed profile calculation means 107 from the 24-hour operation model and the elevator model / specification data. Is calculated. Similarly, the 24-hour torque profile calculating unit 108 calculates a 24-hour torque profile (a data series in which the operation of the elevator is represented by generated torque using time as a parameter). From the calculated 24-hour speed profile and 24-hour torque profile, a 24-hour power profile calculating means 109A based on a regenerative resistance model calculates a 24-hour power profile as viewed from the shaft output of the motor.
[0069]
The power profile obtained by the power profile calculation means 109A for 24 hours based on the regenerative resistance model corresponds to the power profile before the introduction of the energy saving device. By deriving the power profile 116, it is possible to calculate the peak power and the power consumption before the device is introduced. Further, a profile 115 of power consumption by the regenerative resistor can be calculated from the power profile for 24 hours. The power consumption by the regenerative resistor can be reused by introducing the energy saving device, and corresponds to the amount of power that can be saved by introducing the energy saving device. Therefore, the estimation of the energy saving effect evaluated by the electric energy may use the electric energy consumed by the regenerative resistor.
[0070]
Also, the power profile obtained by the power profile calculation means 109A for 24 hours, the information on the type of energy saving device and its control method obtained from the energy saving menu selection means 2 shown in FIG. 1 or FIG. 2, and a battery model database The energy saving device model including the type, control method, and specifications (capacity and rated current, etc.) of the energy saving device is determined by the energy saving device model setting means 110 from the regenerative converter model database 8 or 7. For example, in the case of a battery of regenerative power reuse control, a regenerative power amount in one operation is derived from a power profile obtained by the power profile calculation means 109A for 24 hours, and a battery having N times the capacity is selected. do it. Also, the rated current of the battery can be derived from the regenerative electric energy in one operation. The amount of regenerative electric power in one operation can be obtained by setting conditions at the time of regenerating from elevator model / specification data without using an electric power profile. In this case, the capacity and the rated current of the battery can be uniquely derived by simple processing.
[0071]
Using the energy-saving device model determined by the energy-saving device model setting unit 110, the 24-hour power profile calculation unit 109B considering the energy-saving device model calculates a 24-hour power profile after the introduction of the energy-saving device. Then, from the obtained power profile, the power profile analysis means 111 for 24 hours after the introduction of the device analyzes the charge capacity profile 112 of the battery and the power profile 113 in the power input. The power profile 113 at the time of power supply input is used to calculate the amount of power used and the electricity bill after the device is introduced.
[0072]
In the description of the energy-saving device specification setting means, a method of determining the device specifications in advance has been described. However, the analysis may be performed without determining the device specifications, and the device specifications may be determined based on the result. For example, when regenerative power reuse control is performed using a battery, the power capacity of the battery is set to infinity, a 24-hour power profile calculation is performed, and the maximum value of the battery charging capacity is obtained from the obtained result. The capacity of the battery can also be determined based on this. The battery charge capacity profile 112 is used when such a method is applied.
[0073]
In this way, the energy-saving effect analysis means can analyze the power profiles of the 24-hour period before and after the introduction of the device to more accurately evaluate the energy-saving effect. In addition, the provision of the means for determining the energy-saving device model enables more accurate power profile analysis after the device is introduced. Further, by calculating the result in the form of a 24-hour power profile, it is possible to execute more various power rate calculations, such as involvement of power peaks and reflection of rates by time zone.
[0074]
FIG. 24 shows the processing contents of the electricity cost evaluation unit 11 shown in FIG. 1 or FIG. First, it is determined whether the building in which the target elevator is installed is an apartment (S170). This can be determined from the input data on the type of building of the evaluation data input means 1 shown in FIG.
[0075]
In the case of a condominium building, the maximum value of the input power from the power source is obtained from the power profile at the power input obtained by the energy-saving effect analysis means 10 in FIG. 1, and this value is compared with the electricity rate system database (S172) as contract power. By doing so, the contract power price can be obtained (S171). In addition, the total power input from the power source is obtained from the power profile of the power input, and this value is compared with the electricity rate system database (S172) as the power consumption, whereby the power consumption (S173) can be obtained.
[0076]
If the building is not a condominium building, the total power input from the power supply is obtained from the power profile at the power input, and this value is compared with the electricity rate database (S172) as the power consumption, thereby obtaining the power consumption (S174). Can be requested.
[0077]
As described above, by using the power rate calculation process according to the building type and the 24-hour power profile, more accurate power rate calculation according to the installation status and use status of the elevator can be executed.
[0078]
(4) Details of the result output section
FIG. 7 shows a display screen on the operation terminal of the evaluation result data output means 14 shown in FIG. 1 or FIG. FIG. 7 shows a simple output display of the result of the energy saving evaluation. The total value of the electricity bill and the total value of the power consumption in a certain period (X years) are the difference between the current state and the countermeasures after the countermeasure. Expressed as the required savings. Therefore, the user of the evaluation system can confirm at a glance the current state, the electricity cost after the countermeasures, and the amount of power consumption. In addition, by displaying both the electricity bill and the amount of power used, the demands of users who value savings in terms of money and the demands of users who place importance on savings of power consumption in consideration of the environment are also considered. Can also be accommodated.
[0079]
In FIG. 7, the results of the two methods of the electricity cost saving priority method and the power amount saving priority method are collectively displayed. In this case, the user of the energy saving evaluation system can compare and evaluate which method is preferable. In addition to the above, a method of displaying only a result for a menu selected by the system user (which can be selected by the energy saving menu selection unit 2 in FIG. 1) is also conceivable. Alternatively, either one of the electricity cost and the power consumption (power consumption) may be obtained and displayed.
[0080]
FIG. 8 shows a display screen on the operation terminal of the evaluation result data output means 14 shown in FIG. 1 or FIG. FIG. 8 shows a detailed output display of the results of the energy saving evaluation. The total value of the electricity bill, the total value of the power consumption, and CO in a certain period (X years) are shown. ₂ Numerical values converted to (carbon dioxide) emissions and breakdown of the contents of electricity rates are displayed as reference data. In addition, the total value of the electricity bill, the total value of ₂ Each of the numerical values converted into the emission amount is displayed in three forms, that is, the current state, after the countermeasures, and the saving obtained by the difference between the two. In particular, it is necessary to consider the impact on the environment in the future. ₂ The effect can be directly known by looking at the numerical value converted into the emission amount. In addition, CO ₂ Even if regulations are made on an emission basis, it is easy to respond by looking at these figures. It should be noted that electricity bill, electric power consumption, CO ₂ Any one or any two of the discharge amounts may be obtained and displayed.
[0081]
In FIG. 8, as the reference data, the breakdown of the contents of the electricity tariff, specifically, the current value of the contract power and the value after the countermeasure, and the current value of the power consumption and the value after the countermeasure are displayed. This is especially for the case of apartment buildings, and we aim to show here the specific grounds for reducing electricity costs. In the case of a condominium building, the contract power of the shared system to which the elevator is connected as a load can be reduced, so that it is possible to clearly know that the electricity bill can be reduced by looking at the numerical values of the reference data.
[0082]
FIG. 13 shows a display screen on the operation terminal of the introduction cost output unit 15 shown in FIG. 1 or FIG. FIG. 13 is a display screen displayed when the user of the energy saving evaluation system has not concluded a maintenance contract with an elevator maintenance company or a service company that provides this system. The lease period and the lease cost are clearly indicated on a screen 55 showing the lease period and the lease cost when purchasing as a leased item in the screen 54 relating to the introduction cost of the energy saving device. As described above, not only the energy saving evaluation result but also the cost required for the introduction of the device can be shown, so that more specific information can be shown for the study on the purchase of the energy saving device. In addition, by indicating the equipment introduction cost according to the service purchase form and the status of the maintenance contract, it is possible to more accurately show information regarding the cost. Details of the form of purchase by lease will be described later in the section on business form.
[0083]
In addition, by looking at the energy saving effect and the equipment introduction cost, the user 56 who is interested in the equipment introduction is provided with an item 56 for selecting whether or not a detailed energy saving effect evaluation is desired. It is possible to continue to detailed energy saving effect evaluation.
[0084]

FIG. 14 is a display screen displayed when a user of the energy saving evaluation system has a maintenance contract with an elevator maintenance company or a service company that provides this system. In this case, since the purchase form is a maintenance option, the option validity period and the energy saving option cost are displayed. In this way, when the user of the energy saving evaluation system is a maintenance contractor, information on the cost can be shown more accurately by indicating the device introduction mode and the cost thereof according to the maintenance contractor.
[0085]
In addition, by looking at the energy saving effect and the equipment introduction cost, for the user who is interested in the equipment introduction, an item 59 for selecting whether or not a detailed energy saving effect evaluation is desired is provided. It is possible to continue to detailed energy saving effect evaluation.
[0086]
Hereinafter, the flow of the operation and evaluation process for the energy saving evaluation system for the elevator shown in FIGS. 1 and 2 will be described.
[0087]
FIG. 16 is a flowchart showing an example of the operation and evaluation process flow for the elevator energy saving evaluation system shown in FIGS. 1 and 2. The flow is as follows. 1) Input of various data related to the building or elevator owned or managed (S120). 2) Selection of the energy saving menu (S121).

In the case of 17, the cost of introducing the energy-saving device is displayed in a list, divided into purchase forms. In this case, the user of the energy-saving evaluation system can compare the device introduction costs at a glance.
[0089]
FIG. 18 is a flowchart illustrating another example of the operation and evaluation process flow for the elevator energy saving evaluation system illustrated in FIGS. 1 and 2. The flow is as follows. 1) Input of various data relating to the building or elevator owned or managed (S140). 2) Implementation of energy saving effect evaluation calculation (S141). 3) Output of a list of energy saving effects (saving electricity cost and electric energy) (S142).

A list of expenses for each case is presented separately for cases where a maintenance contract is made and cases where a maintenance contract is not made. 5) Apply for a request for detailed evaluation of energy saving effects (S144). In the case of FIG. 18, the energy saving effect is displayed as a list separately for a case of an apartment building and for the case where it is not, and the energy saving device introduction cost is displayed as a list of purchase types. In this case, the user of the energy saving evaluation system does not need to select the purchase mode or the energy saving menu at the time of input, and the result displays a list divided into each item. Therefore, the user of the energy-saving evaluation system can save the trouble of selection and can compare and evaluate each item on the results shown in the list.
[0090]
FIG. 19 is a diagram summarizing how the elevator energy saving evaluation system shown in FIG. 1 or 2 is used in an actual situation and how it is used by hardware.
[0091]
First, FIG. 19A shows a usage and a usage form in a case where a customer who wants to purchase an energy saving device evaluates itself. The customer 202 who uses the energy-saving effect evaluation system inputs data information regarding the customer's elevator and building or maintenance customer authentication data information on a personal computer or a terminal such as the portable terminal 101 owned by the customer (as described above). (Equivalent to the processing of the data input unit). The evaluation data input means 1 in FIG. 1 or the maintenance customer authentication data input means 16 in FIG. 2 transmits the information shown in FIGS. 4 to 6 to a terminal of a customer who is a system user via a communication network. A screen for inputting is displayed, for example, in a homepage format. Then, the input information is transferred to the computer 102 of the energy saving service provider via the communication network, and the input means in FIGS. 1 and 2 receives the information, where the operation pattern is estimated, and the model and specification of the elevator are checked. The estimation and the energy saving effect analysis (corresponding to the processing of the estimation unit and the analysis unit already described) are performed. Here, the personal computer or portable terminal 101 owned by the customer and the computer 102 of the energy saving service provider are connected by a communication network such as the Internet. The evaluation results obtained from the results of the energy saving effect analysis in FIGS. 1 and 2 are displayed on a personal computer or a portable terminal 101 owned by the customer via the communication network (corresponding to the processing of the result output unit).
[0092]
In the case of FIG. 19A, the feature is that a customer who wants to purchase an energy saving device evaluates it alone. As described above, in the elevator energy saving evaluation system shown in FIG. 1 or FIG. 2, the input items required for the evaluation are such that ordinary people who do not know the elevator in detail can input. Use forms are possible. And since it can be evaluated by the customer alone, it can be used easily, and since it can be used on the Internet, it can be easily used. Therefore, it is possible to have more people evaluate. This means that providers of energy-saving evaluation systems will have more opportunities to purchase energy-saving equipment, and at the same time, from an environmental point of view, the energy saving of elevators will progress, and energy waste will be reduced. become.
[0093]
Next, FIG. 19B illustrates a usage form in which the energy saving service provider 203 performs an energy saving evaluation of an elevator owned by the customer 204 with respect to the customer 204. This corresponds to, for example, a case where the maintenance worker evaluates the energy saving effect of the customer's elevator after the maintenance work, or a case where the energy saving service provider goes to the customer and evaluates the energy saving effect in front of the customer. . The energy saving service provider 203 inputs necessary data on the personal computer or the portable terminal 103 owned by the energy saving service provider 203. The input data is transferred to the computer 104 of the energy saving service provider, where the operation pattern is estimated, the elevator model and specifications are estimated, and the energy saving effect is analyzed. Here, the personal computer or portable terminal 103 owned by the energy saving service provider and the computer 104 of the energy saving service provider are connected by a communication network such as the Internet. The evaluation result obtained as a result of the energy saving effect analysis is retransmitted to the personal computer or the portable terminal 103 owned by the energy saving service provider 203 and displayed on the screen. The energy-saving service provider 203 shows the result to the customer 204 who wants to evaluate the energy-saving effect, and explains how much energy-saving effect can be obtained and what the necessary introduction cost is.
[0094]
In the case of FIG. 19B, since the energy saving service provider 203 who is familiar with the contents of the energy saving evaluation system of the elevator performs the evaluation,
As compared with the case where the step 204 executes, the selection of the input items and the like can be performed more accurately. In addition, since the evaluation result of this system is only approximate, the energy saving service provider 203 can directly teach the customer 204 advice such as how much error the evaluation result includes.
[0095]
FIG. 19C shows a case where the elevator maintenance company evaluates the customer. That is, this example shows a usage mode in which the energy saving service provider adds the evaluation result of the energy saving effect to the maintenance result report that is periodically reported to the customer 205 who has a maintenance contract. In this case, the computer 106 of the energy-saving service provider in which the energy-saving effect evaluation system for the elevator is installed extracts information on the elevator from the maintenance database of the customer 205 who has the maintenance contract, and calculates the energy-saving effect. Then, the result is additionally described in a maintenance result report periodically submitted to the customer 205.
[0096]
In the case of FIG. 19C, the customer 205 can automatically know the evaluation result without knowing the existence of the elevator evaluation system. In addition, for an elevator maintenance company, there is an advantage that the effect of introducing the energy saving device can be directly appealed to the customer.
[0097]
The configuration of the energy saving evaluation system for the elevator shown in FIGS. 1 and 2, the overall processing content, the processing content for each element, the processing flow, the usage form, and the like have been described above. In the following, the business concept and the flow of contract and implementation for the introduction of an energy-saving device using this elevator energy-saving evaluation system will be described. It should be noted that the flow of services from the introduction of the energy-saving evaluation system of the elevator to the introduction of the energy-saving device and further to the after-care after the introduction of the device has already been described with reference to FIG. Here, the description will focus on the contract form (business form) for introducing the energy saving device.
[0098]
FIG. 25 shows a contract form for introducing an energy saving device between an elevator maintenance service company (also serving as an energy saving service company) and a building owner or a resident who has already concluded an elevator maintenance contract with that company. It is a figure. In this case, the building owner or the resident pays the maintenance service company for the elevator a maintenance option fee for installing and operating the energy saving device. Here, this maintenance option payment is basically performed by periodically paying a certain amount of money in the same manner as a normal maintenance price, but may be collectively paid. In return, elevator maintenance companies will install and operate energy-saving equipment. As a result, the building owner or occupants can achieve savings in electricity costs and power consumption by energy saving devices.
[0099]
In this way, by contracting as one of the maintenance options, for the owner or resident of the building on which the energy-saving device is purchased, the installation cost of the device is dispersed and reduced in time, and the desired energy-saving effect is obtained. If the service is not possible, the service can be canceled, and the maintenance service company of the elevator has an advantage that the cost of operating the energy-saving device (for example, the cost for inspection and maintenance) can be included in the maintenance option cost, which is advantageous.
[0100]
FIG. 28 shows the details of the contract form of FIG. 25 as a time-series process. First, the owner or resident of the building with a maintenance contract simply evaluates (approximately evaluates) the effect of introducing the energy-saving device using the energy-saving evaluation system on a personal computer. When the owner or the resident of the building is satisfied with the evaluation result, the elevator maintenance service company (energy saving service providing company) is requested to perform a detailed evaluation of the effect of introducing the energy saving device. The maintenance service company that receives the request performs detailed evaluations, such as actual measurement of the operation data of the building, and presents the results. If the owner or resident of the building is further satisfied with the result of the evaluation, a contract for the introduction of energy-saving equipment is made as an additional option in the maintenance menu. Then, the elevator maintenance company installs and operates energy-saving devices in the building. Thereafter, the building owner or resident will periodically pay the maintenance service option to the elevator maintenance service company, and the elevator maintenance service company will periodically report the energy saving effect after the introduction.
[0101]
As described above, the owner or the resident of the building can perform the simple evaluation by the energy saving evaluation system by himself / herself, so that the apparatus can be introduced after knowing the prospect of the energy saving effect. In addition, since the device can be introduced as an option of the maintenance menu, the cost of introducing the device can be dispersed and reduced over time. On the other hand, the elevator maintenance service company can collect the cost of operating the energy saving device in the maintenance option cost.
[0102]
FIG. 29 illustrates details of the contract form of FIG. 25 as a time-series process, and illustrates an example of a contract process different from FIG. 28 is different from the process of FIG. 28 in that first, the maintenance staff of the elevator maintenance service company simply evaluates the effect of introducing the energy saving device by using the energy saving evaluation system on a portable terminal or a personal computer. Then, if the result is as desired by the owner or the resident of the building, a detailed evaluation of the effect of introducing the energy-saving device is requested to the elevator maintenance service company, and thereafter, the same process as in FIG. 28 is followed.
[0103]
In this case, in the first energy-saving evaluation, the maintenance staff of the elevator maintenance service company who is familiar with the contents of the energy-saving evaluation system of the elevator performs the evaluation, so that selection of input items and the like are performed accurately. There is an advantage that a more reliable evaluation result can be obtained. In addition, since the evaluation result indicated by the energy saving evaluation system can be directly received from the maintenance staff of the elevator maintenance service company, the result can be understood more accurately.
[0104]
FIG. 31 shows details of the contract form of FIG. 25 in chronological order, and shows an example of a contract process different from those of FIGS. 28 and 29. The difference from the processes of FIGS. 28 and 29 is that first, a simple evaluation of the effect of introducing the energy saving device is presented in a regular report of the maintenance result from the elevator maintenance service company. Then, if the result is as desired by the owner or the resident of the building, a detailed evaluation of the effect of introducing the energy-saving device is requested to the elevator maintenance service company, and thereafter, the same process as in FIG. 28 is followed.
[0105]
In this case, the building owner or resident can automatically know the evaluation result without knowing the existence of the elevator evaluation system. In addition, for an elevator maintenance service company, there is an advantage that the effect of introducing an energy saving device can be directly appealed to customers.
[0106]
FIG. 26 is a diagram showing a contract form for introducing an energy-saving device between an elevator maintenance service company and a building owner or resident who has not concluded an elevator maintenance contract with the company. In this case, the elevator maintenance service company installs and operates energy-saving devices in the building free of charge. In response, the building owner or resident will sign a new maintenance contract or return a portion of the saved electricity bill.
[0107]
In this case, there is an advantage that the building owner or the resident can introduce the energy-saving device at zero cost for the energy-saving device, while the maintenance service company of the elevator can acquire a customer who newly signs a maintenance contract. There are advantages. Such a contract is applicable if the building owner or resident owns an elevator that has passed the year of service that requires maintenance and inspection and is considering whether to enter into a maintenance contract. It will be a solution to the benefits for both service companies.
[0108]
FIG. 30 shows the details of the contract form of FIG. 26 as a time-series process. First, a building owner or a resident (who has not concluded a maintenance contract) simply evaluates the effect of introducing an energy-saving device using an energy-saving evaluation system on a personal computer. If the building owner or resident is satisfied with the result of the evaluation, request the elevator maintenance service company to conduct a detailed evaluation of the effect of introducing the energy saving device. The maintenance service company that receives the request performs detailed evaluations, such as actual measurement of the operation data of the building, and presents the results. If the owner or resident of the building is further satisfied with the result of the evaluation, a new maintenance contract is concluded with the maintenance service company. Then, the maintenance service company installs and operates the energy saving device free of charge. After that, the elevator maintenance service company regularly reports the energy saving effect after the introduction.
[0109]
FIG. 27 is a diagram showing a contract form for introducing an energy saving device between an elevator maintenance service company and a building owner or resident who has not concluded an elevator maintenance contract with the company. The point in this example is that the energy-saving device is introduced by a lease contract. The building owner or resident pays a lease for the installation and operation of the energy-saving device to the elevator maintenance service company. In return, elevator maintenance companies will install and operate energy-saving equipment. As a result, the building owner or occupants can achieve savings in electricity costs and power consumption by energy saving devices.
[0110]
By making a lease contract in this way, the owner or the resident of the building on the side of purchasing the energy-saving equipment has the advantage that the equipment introduction cost is dispersed and reduced in time, and if the desired energy-saving effect cannot be obtained, the contract is made. There is an advantage that can be canceled. In addition, the maintenance service company of the elevator has an advantage that the cost of operating the energy-saving device (for example, the cost for inspection and maintenance) can be collected by being included in the regularly paid lease cost.
[0111]
FIG. 32 shows the details of the contract form of FIG. 27 as a time-series process. First, the owner or resident of a building that has a maintenance contract simply evaluates the effect of introducing an energy-saving device using an energy-saving evaluation system on a personal computer. If the building owner or the resident is satisfied with the evaluation result, request the elevator maintenance service company to perform a detailed evaluation of the effect of introducing the energy saving device. The maintenance service company that receives the request performs detailed evaluations, such as actual measurement of the operation data of the building, and presents the results. If the owner or resident of the building is further satisfied with the result of the evaluation, a contract for the introduction of energy-saving equipment is made as a lease contract. Then, the elevator maintenance company installs and operates energy-saving devices in the building. Thereafter, the owner or resident of the building will periodically pay the leasing fee to the elevator maintenance service company, and the elevator maintenance service company will periodically report the energy saving effect after the introduction.
[0112]
As described above, since the energy-saving device can be introduced by the lease contract, the device introduction cost can be dispersed in time and reduced. On the other hand, the maintenance service company of the elevator can collect the cost of operating the energy saving device in the lease price.
[0113]
