Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator, such as an elevator, an escalator or a moving sidewalk, and a method for calculating a maintenance fee, a maintenance method useful for calculating and billing a maintenance fee, and an air conditioner other than the elevator. The present invention relates to a maintenance method for facilities in a building including the above.

[0002]

2. Description of the Related Art Elevators such as elevators, escalators, moving walkways, etc., are mechanical equipment that is required to always exhibit safe and predetermined performance for a long period of time as a transportation means in a building for transporting people. Inspection is required. Therefore, it is necessary to perform maintenance, inspection and maintenance periodically or according to the situation. In addition, since the elevator is a complicated device and its maintenance work involves danger unless it is an expert, it is generally performed by a specialized maintenance company. As means for appropriately performing maintenance work and performing legal inspection without omission, for example, Japanese Patent Application Laid-Open
JP-A-255558 and JP-A-9-240945 propose an elevator control device capable of prompting the maintenance and inspection when the maintenance and inspection have not been performed for a predetermined period or more.

[0003] In an elevator whose operation is automated, there is no labor cost for the operation itself, and the daily operating costs are electricity charges and maintenance charges. This operating cost is paid by the owner of the building or the resident of the building as the co-owner. As a method of paying these maintenance fees, a full maintenance contract for guaranteeing initial performance at a fixed monthly fee is paid, or a necessary amount is paid each time for periodic inspection and maintenance work in case of failure.

[0004] When a failure occurs without receiving daily maintenance work, a large amount of cost is required at a time, and it takes a long time to recover from the failure. For this reason, in the current domestic market, paying a fixed maintenance fee every month often makes a full maintenance contract that guarantees the maintenance of the predetermined performance.

[0005] As a publicly known technology related to the usage fee of an elevator, see “2. Transportation and Transportation” in the symposium “Is Ultra-High Rise Meaning?” (Held on December 7, 1999) hosted by the Architectural Institute of Japan. The section “Transportation system” contains the results of a questionnaire asking whether or not to collect the usage fee according to the usage as a common service fee.

[0006]

The maintenance fee based on the full maintenance contract is a fixed amount, and there is a problem that some users are not always satisfied.

[0007] Further, in a shared building such as an apartment, maintenance fees are collectively collected as a management fee, a common service fee, and the like. However, residents who have little use of the elevator may be dissatisfied. A first object of the present invention is to provide a method for calculating a maintenance fee for an elevator or a facility in a building, which calculates an appropriate maintenance fee that is easy for a user to satisfy.

Another object of the present invention is to provide a method of collecting maintenance fees for an elevator or a facility in a building, which can save the trouble of collecting the maintenance fees.

[0009]

[Means for Solving the Problems] Elevators such as elevators and escalators are used as main transportation in the building.
It constitutes a part of a building structure, and is often used continuously over a long period of 20 years or more regardless of the season. Because of this, its downtime impact is enormous,
Substitutes with stairs are not possible in high-rise buildings. Regarding the maintenance of elevators, even if they are renewed, the mainstream is the replacement of the entrance and exit design and the interior of the car, etc., and it is rare to remove or replace the building for a long time. On the other hand, since elevators are mechanical equipment that carries people safely, statutory inspections are required to maintain safety.In this sense, inspection and adjustment are important for other equipment in the building. Not the ratio of

[0010] For this reason, the maintenance (contract) of the elevator is to guarantee the transportation of people safely for many months without interruption during the day by partial repair and parts replacement based on maintenance and inspection. be able to.

[0011] Therefore, it is important to perform maintenance and inspection on a part and part basis, but the parts and parts are subject to inspection and inspection such as generation of fatigue and wear depending on the aging status and usage (operation) status.
Some items need to be adjusted or replaced. The work cost required for the inspection and adjustment, the component cost required for replacement, and the work cost occupy most of the maintenance cost.

For these reasons, it is reasonable to reflect the aging or use (operating) status of the elevator in the maintenance fee of the elevator, which guarantees safe transportation of people while minimizing downtime. it is conceivable that.

In a preferred embodiment of the present invention, the lower the age of the elevator or the equipment in the building, the smaller the maintenance fee is calculated.

In another embodiment of the present invention, the maintenance fee for the case where the age and / or operation status of the elevator or the facility in the building is lower than the scheduled value is reduced to the maintenance fee when the age and / or operation status exceeds the scheduled value. The calculation is made so that the maintenance fee in the case is reduced.

[0015] In another embodiment of the present invention, the maintenance fee for the elevator is allocated according to the usage status or the living floor of the resident who uses the elevator.

Further, in another embodiment of the present invention,
A step of calculating a maintenance fee according to the aging and / or operation status of the elevator; a step of notifying the calculated maintenance fee to the financial institution; and a step of the financial institution deducting the maintenance fee from the account of the maintenance fee bearer of the elevator. And characterized in that:

[0017] In this manner, a more appropriate maintenance charge is determined by the age (newness, oldness) of the elevators and equipment in the building. It is easy to be. Further, for example, if there is a difference in the usage status between a certain building and another building, or if there is a difference in monthly usage status in the same building, the usage status can be reflected in the maintenance fee. Furthermore, the residents of the first and second floors who rarely use the elevator can reflect the usage status in the maintenance fee in such a manner that the burden is reduced as compared with the residents of the higher floors who frequently use the elevator.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention can be applied not only to elevators such as elevators, escalators or moving walkways, but also to equipment in buildings such as air conditioners. Hereinafter, an embodiment of the present invention will be described by taking an elevator as an example. This will be described with reference to the drawings.

FIG. 1 is a diagram showing the relationship between the usage status or aging status of a lift and a maintenance fee according to an embodiment of the present invention.

As shown by the dotted line in FIG. 1A, the maintenance fee based on the conventional full maintenance contract is a fixed amount irrespective of the usage status every month. On the other hand, in the present example, the monthly maintenance fee is reduced when the elevator is new or the usage status is small using the function of the aging status or the usage status.

As shown in FIG. 1, there are the following five examples of calculating the maintenance fee from the aging status or the usage status.

(1) The maintenance fee is directly proportional to the aging status and / or the usage status. (2) The reference fee is determined, and if the aging status and / or the usage status does not reach the specified value, the maintenance fee is discounted ( 3) The maintenance fee is rapidly increased as the aging status and / or usage status increases. (4) Although the maintenance fee is directly proportional to the aging status and / or usage status, an upper limit and / or a lower limit are set for the maintenance fee. (5) Although the maintenance fee is made proportional to the aging status and / or the usage status, the maintenance fee is set in steps such as 100 yen increments. FIG. 2 is a diagram showing a system configuration according to an embodiment of the present invention.

An operation control means 11 is provided in the control device 10 of the elevator, and controls the operation of the car 22 in response to a signal from the hall call button 21. In the control device 10, an operation status measuring means 12 is provided. The operating status measuring unit 12 includes a main device data storing unit 13, a peripheral device data recording unit 14, and a use status data recording unit 15 for recording data as shown in the figure.

The maintenance fee calculating means 30 is a mobile terminal that can be carried by maintenance personnel. In this example, the portable maintenance fee calculating means 30 includes an aging situation data recording means 31 for storing aging situation data and a maintenance dispatch data recording means 32. The maintenance staff can connect to the control device 10 with a cable by a connector provided at a predetermined location of the target elevator. Similarly, the building management device 40
Can also be connected.

Thus, aging data recording means 31 for recording and updating aging data necessary for calculating the maintenance fee according to the aging condition, and a built-in recording means 31 for calculating the maintenance fee Maintenance fee calculation means 30
Is composed. In this case, the age of the corresponding elevator is used as the horizontal axis of FIG. 1, and the maintenance fee is reduced when the age is small, that is, when the age is large.

On the other hand, in order to reflect the operation (use) state, the operation state measuring means 12 shown in FIG. 2 and the maintenance charge calculating means 30 for calculating the maintenance charge are required. In this case, the operating status of the corresponding elevator is used as the horizontal axis in FIG. 1, and the lower the operating status, the lower the maintenance fee for the case where the operating status is higher.

It is desirable to calculate the maintenance fee in consideration of the above-mentioned aging situation and the above-mentioned operation situation. Hereinafter, an embodiment in which the aging situation and the operation situation are considered simultaneously will be described in detail.

The operating condition measuring means 12 includes information such as the number of times the elevator has traveled, the traveling distance, the traveling time, and the number of times the driving direction has been reversed.
Measure and record data 13 of the main equipment that is the center of maintenance charge calculation. If the elevator is operated intermittently like an elevator, the number of times of running and the number of direction reversals will be data leading to factors such as wear and damage of each part, and if the device is operated continuously like an escalator, the running It is suitable for calculating a maintenance fee because it serves as a guide for maintenance work requiring time. Further, data 14 of peripheral devices such as the number of times of button operation and the lighting time are also effective.

Data 32 relating to the number of non-predetermined dispatches of the maintenance staff to the building, which is an important item in the maintenance fee, is also included.
In this embodiment, is assumed to be recorded in the maintenance fee calculating means 30 which is a portable device possessed by a maintenance person.
Therefore, the dispatch count data is recorded in the dispatch count recording means 32, and the dispatch data is updated by inputting by the maintenance staff every time the dispatch is performed.

Further, the operating status measuring means 12 measures the usage status data 15 for each floor. Car 22
Alternatively, when the hall is provided with the individual recognition means 23, the usage count data 15 can also measure the number of times of use for each individual / door to door. The personal recognition means 23 detects hardware such as a door key or an ID card owned by each door or each individual, uses a biometric method such as fingerprint, voice, image processing, or uses an encryption registered in advance. Any method, such as recognizing an individual by an operation, may be used.

The maintenance fee calculating means 30 includes a building management fee obtained from a building management data storage device 41 of a building management device 40 installed in the building and having functions such as air conditioning management, and a maintenance fee for its own elevator. It is also possible to add up the maintenance fee of the elevator calculated by the calculation means 30.

Although FIG. 2 shows an elevator as an example, the same applies to the case where other elevators such as an escalator and a moving walkway are used, so that illustration of these other elevators is omitted.

Although the aging status recording means 31 is shown as an example provided inside the maintenance fee calculating means 30, it may be arranged in the control device 10. It may be data of the aging situation.

Since the operating condition measuring means 12 is used for measuring the operating condition of the elevator, it can be used as a separate device, as a partial function in the control device 10, or as a hall call button. 21 or the car 22 may be provided.

Further, the maintenance fee calculating means 30 can also be arranged as a part of a corresponding elevator or in a building as a device combined with the control device 10 and the operation status measuring device 12, and conversely, provided in the maintenance center. It can also be implemented on the server computer side.

As described above, the maintenance fee calculation device targeted by the present invention may be configured as a single device or distributed to a plurality of devices, as long as the maintenance fee can be calculated. Therefore, a configuration of only the maintenance fee calculating means 30 is possible,
It is also possible to disperse the apparatus into a plurality of devices and to configure a part including the operation status measuring means 12 and the maintenance fee calculating means 30.

FIG. 3 is a flowchart of the maintenance fee calculation process 100.

The maintenance charge calculation processing 100 is executed by the maintenance charge calculation means 30 as an operation by a maintenance person or a periodic processing every month.

In step 100-1, operation status data such as main device data 1, peripheral device data 14, and use status data 15 recorded in the operation status measurement means 12 are read.

In step 100-2, the aging status data 31 is read.

In step 100-3, the maintenance dispatch data 32 is read.

Step 100-4 is a process of setting a maintenance fee according to the operation status, which is the main point of the first invention. At least the operation data read in step 100-1 and / or the operation of step 100-1 are set. The maintenance fee is calculated based on the aging status data read in step 2.

This calculation can be determined by, for example, Equation 1.

Maintenance fee = func1 (operating status) + func2 (aging status) + func3 (dispatch status) + const (equation 1) Here, the maintenance fee calculation function func1 relating to the operating status in equation 1 is in a broad sense as illustrated in FIG. It is a monotonically increasing function. The function func2 relating to the aging situation calculates the maintenance fee relating to the number of years elapsed since the installation of the elevator, or the model and control method of the elevator, the device configuration / device configuration, and the like.

As an additional item, step 100
The charge for emergency dispatch of maintenance read in -3 is func
Set with 3.

The constant term const relates to a basic charge.

In the maintenance of the elevator, there are items depending on the operation status such as rope wear, and items related to the aging status such as a battery for a power outage, and the operation status and the aging status are separately reflected in the maintenance fee calculation. It is reasonable to do so.

Here, if the type of the elevator is different, or if the standard equipment and the additional equipment provided for the elevator are different, the maintenance fee should be different.

For example, it is natural that the cost of securing the parts required for maintenance and replacement is different between the current model and the model installed at the time 20 years ago. For this reason, the difference between models is, for example,
It is necessary to take it into func2. The difference between the standard equipment and the additional equipment is that, for example, the lighting in the car is based on a standard fluorescent light, the incandescent lamp is used as an additional equipment due to design change, or a liquid crystal display is provided as an additional equipment to the elevator hall. The maintenance cost varies depending on the case where Therefore, the function fu for the aging situation
nc2 incorporates items related to the model of the elevator, control method, device configuration / device configuration, etc.
It is reasonable to incorporate the operation status into the maintenance charge calculation function func1 relating to the operation status as No. 4.

Step 100-5 is a process related to the maintenance fee distribution according to the second aspect of the present invention, and is executed when it is necessary to determine the distribution.

The allocation is determined according to Equation 2 for each floor, and when the individual recognition unit 23 can determine each house, Equation 3 is used.
Performed by

Each floor charge = k × maintenance charge × number of times of use of each floor / total number of times of use + (1−k) × maintenance charge / number of floors (Equation 2) Fee of each unit = k × maintenance charge × number of times of use of each unit / total number of times of use + (1−k) × maintenance fee / number of units (Expression 3) Here, k in Expressions 2 and 3 is a coefficient, and is 0 or more and 1
The following is assumed. With this k, it is possible to adjust the distribution amount according to the number of times of use for each floor and each house and the distribution amount common to the whole. The number of times of use of each floor is i-th floor from the lobby floor, i-th floor from the i-th floor to the lobby floor, i-th floor from the i-th floor to j-th floor, and j-th floor 0.5 degrees each. Count. When the individual recognition means 23 is not used, the maintenance charge share of each house can be determined by dividing each floor charge by the number of each floor.

Further, Steps 100-6 to 100-8 are processes for connecting to the building management apparatus 40 and summing the other building management fees and the maintenance fees for the elevators. If addition with other building management data is necessary in step 100-6, the building management data 41 is read from the building management device 40 in step 100-7, and the building bill is added to the bill for elevator maintenance in step 100-8. Add up management bills.

After performing the above-described necessary processing, if it is necessary to issue a bill for a maintenance fee, step 100
A bill is prepared at -9. If an automatic debit procedure is performed in advance, a receipt may be used instead of an invoice. The details will be described later with reference to FIGS.

In the flowchart of the maintenance charge calculation processing 100 shown in FIG. 3, one or more steps can be deleted as necessary. For example, the only required item may be a step of determining a maintenance fee according to the aging status and / or the operation status in step 100-4. In this case, the functions func1 and / or func2 included in step 100-4 and Equation 1 can be said to be a maintenance fee calculation process. Further, when the function func3 relating to the dispatch situation is used in Expression 1, it means that the step of calculating the maintenance fee based on the number of dispatches has been performed.

In step 100-5, only the process of allocating the maintenance fee according to the operation status can be performed, and step 100-5 can be said to be the distribution amount determination process. Steps
In 100-5, Equation 2 is a step of determining the distribution amount for each floor, and Equation 3 is a step of determining the distribution amount for each house.

Step 100-8 is a step of calculating the billed amount that is added to the building management fee.

FIG. 4 shows an example of a bill output in the step of integrally creating a report of a use situation and a bill for a maintenance fee executed in step 100-9.

In FIG. 4, an underlined portion is a portion that is input every time.

In this embodiment, a maintenance method and a maintenance device are provided in which the maintenance fee varies according to the monthly usage status, and the monthly usage status and operating status are measured as basic data. Simultaneously reporting the usage status and operation status based on the fluctuating maintenance fee using this will help users to deepen their satisfaction and understanding.

One example is the bill output of FIG.

In the invoice of FIG. 4, the "report of usage status" of the first item is a usage report portion, and the "charge of maintenance fee" of the third item is a bill portion. By outputting these both as one, the recipient can know the basis for calculating the maintenance fee.

Further, in the bill, if necessary, the billing amount for each floor / house and the billing amount for other building management expenses are also added to create a bill for each floor / house.

Further, by adding the items exemplified in the second section, “Analysis of operation status”, the user can further understand the elevator equipment, and the user service can be improved.

According to the above-described embodiment, there is an effect that the burden is not imposed on the building manager, and the maintenance fee according to the benefit can be automatically calculated.

Next, a description will be given of the provision of a fee transfer system that saves the burden on the fee bearer regarding the collection of the maintenance fee.

As described above, it is reasonable to calculate the maintenance fee of the elevator according to the aging status and the operation status. However, for this reason, there is a complication that the maintenance fee fluctuates for each maintenance opportunity.

FIG. 5 is an overall system configuration diagram of an embodiment of the present invention.

It is assumed that a certain building 51-A adopts a maintenance fee according to the aging status and the operation status, and that the maintenance fee is collectively paid by the building management association 52 in the building. In addition, the other buildings 51-B similarly adopt maintenance fees according to the aging status and the operation status, and further calculate the share of each house for the maintenance fees, and assume that each resident 53 bears. I do.

Each of the buildings 51-A and 51-B is a computer network,
A maintenance center 55 and a financial institution 56 are connected by a network 54 such as a telephone line. The maintenance center 55 can be connected to the internal or external maintenance fee calculation means 30 and can have the calculated maintenance fee data.

Further, in the transfer of fees, the user, that is, each building management association 52 and / or each resident 53, is set in advance so that a financial institution 56 such as a bank or a credit company can act for the agency.
It is assumed that agreements and procedures have been made with the government.

FIG. 6 is a flowchart of the maintenance fee transfer processing 200.

The maintenance fee calculating means 30 of the maintenance center 55
Collects operation status data for each building 51 via the network 54 in step 200-1. Here, the step 200-1 is necessary when the maintenance fee corresponds to the operation status, and is not always necessary when the maintenance fee only corresponds to the aging status.

Next, in step 200-1, the maintenance charge calculation processing 100 is executed using the collected data for each building as described above.

The maintenance center 55 proceeds to step 200-2.
Then, the maintenance fee calculated in the maintenance fee calculation process 100 is converted into electronic data via the network 54 or by a method such as mailing a bill, as indicated by the bold arrow maintenance fee notification, ie, the user who is the charge bearer, Notify each building management association 52 and / or each resident 53. Step 200-2 can be omitted for a building for which the notification process is not required in advance.

In step 200-3, the calculated maintenance fee and the bearer thereof are notified to the financial institution 56 as indicated by the bold arrow maintenance fee notification.

The financial institution 56 performs a process of withdrawing the notified maintenance fee from the user's account in step 200-4, as indicated by the bold arrow maintenance fee withdrawal.

As shown by the maintenance fee payment indicated by the thick line arrow, the deducted maintenance fee is calculated in the withdrawal step 200-5.
Payment is made from the financial institution 56 to the maintenance company.

Step 200-4 and step 20
The order of 0-5 is such that the financial institution 56 is a credit card company or other user who is a charge bearer (each building management association 5).
