Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator maintenance device for elevators, escalators, moving walkways and the like, and more particularly to an elevator maintenance device for formulating an elevator maintenance plan and calculating a maintenance fee.

[0002]

2. Description of the Related Art Generally, elevators such as elevators, escalators, and moving walkways are used to move a person while they are mounted on the elevator, so that they have stable operating characteristics for a long period of time and are sufficiently safe. Must be. For this reason, it is necessary to perform maintenance work such as inspection and maintenance on the elevator regularly or according to the operating conditions. Moreover, since the maintenance work of the elevator is a special work, specialized maintenance personnel are required. It is usually entrusted to an existing maintenance company.

[0003] Conventionally, when performing the above-mentioned maintenance work of the elevator, the maintenance fee arrangement is roughly divided into the following two types of contracts between the customer who owns the elevator and the maintenance company. That is, one is a contract for paying all the costs of equipment operation guarantee, equipment failure response, legal inspection and periodic inspection for a long period of time, for example, 20 years (hereinafter, this contract is called a full maintenance contract). The other one is that it only includes the legal inspection and periodic inspection charges, and the contract for paying the replacement parts fee at the time of equipment failure or equipment deterioration and the work cost each time the maintenance work is performed (hereinafter, This contract is called a POG contract).

When a full maintenance contract is made out of these two types of contracts, all maintenance charges for long-term, eg, 20-year equipment operation guarantee, equipment failure response, legal inspection and periodic inspection are apportioned monthly. Pays,
For the first 10 years or so, when the proportion of elevator failures is low, there is a fear that the customer may feel that the maintenance fee is too high. On the other hand, when a POG contract is made, the monthly payment is less than that of a full maintenance contract, but a large amount of maintenance fee is charged when an elevator breaks down or when parts are replaced due to equipment deterioration. You have to pay in bulk. Therefore, there is a problem that the customer is not always satisfied with the maintenance fee of the elevator. Further, neither the full maintenance contract nor the POG contract does not take into consideration the stoppage of the physical distribution caused by the stop due to the failure of the elevator, the compensation to the user, and the risk to the customer.

Therefore, as a means for calculating the maintenance fee of the elevator according to the operating status of the elevator, for example, Japanese Patent Laid-Open No.
As described in Japanese Patent Application No. 01-256380, a maintenance fee is automatically calculated according to the monthly average traveling time of the elevator, the number of years after the elevator is delivered, and the content of the maintenance product. It has been proposed to conclude the failure response rank in advance at the time of contract and pay back part of the maintenance fee when the failure recovery time of the elevator exceeds the contract time.

[0006]

By the way, in the above-mentioned prior art, an elevator installed in a station used by an unspecified number of people, an elevator installed in an office building used by a specific person, or Even for elevators for patient transportation provided in hospitals, etc., maintenance work for elevators is performed according to a uniform work plan regardless of the purpose of use of these elevators. There is a problem that the maintenance fee cannot be set. For example, in a hospital or the like that has an elevator for transporting patients, if the elevator for transporting patients stops due to a failure, serious problems related to the life of the patient may occur. It is required to set up a maintenance work plan for elevators.

[0007] Further, since the service life of elevator parts varies depending on the operating environment and operating conditions and is generally different from the originally designed service life, if parts are replaced at a time based on the originally designed service life, There are cases where parts are replaced before the actual life, or parts are replaced after a failure occurs after the actual life, that is, there is a problem that they do not fit the actual situation.

The present invention has been made in view of the actual situation in the prior art as described above, and its main purpose is to calculate the customer's loss amount associated with the stop of the elevator and to plan the maintenance work of the elevator. An object of the present invention is to provide an elevator maintenance device capable of calculating the elevator maintenance fee according to the customer's desired warranty.

Another object of the present invention is to provide an elevator maintenance device capable of setting a component replacement cycle that matches the actual life of elevator components.

[0010]

In order to achieve the above object, the elevator maintenance device of the present invention is an elevator maintenance device having an elevator maintenance center connected to each elevator via a communication line. The elevator maintenance center comprises a contract terminal connected via a communication line and a maintenance work terminal connected to the elevator, and the elevator maintenance center provides a loss amount of an elevator owner customer when the elevator stops due to a failure, Loss amount calculation means for calculating using common data,

Means, operation data collection means for collecting operation data of the elevator, operation data file for each customer for storing the operation data,
The maintenance work record collecting means for collecting the maintenance work record of the elevator and the maintenance work record file for each customer for storing the maintenance work data of the elevator are configured.

In the present invention thus constructed, the loss amount of the customer when the elevator stops due to a failure is calculated by the loss amount calculating means using the common data, and the elevator maintenance work plan according to the loss amount is calculated. The maintenance work is set by the maintenance work setting means, and the maintenance charge calculation means calculates the maintenance charge according to a predetermined formula using the charge calculation common data based on the set maintenance work plan. Therefore, the loss amount of the customer due to the stop of the elevator Can be used to plan elevator maintenance work, and the elevator maintenance fee can be calculated according to the customer's desired warranty. Also, since the operation data of the elevator is collected by the operation data collection means and stored in the customer-specific operation data file, the maintenance work record of the elevator is collected by the maintenance work record collection means and stored in the customer-specific maintenance work record file. You can always update the operation data and replacement record data used for parts life analysis and setting to the latest data and set the parts replacement cycle that matches the latest actual life.
