Elevator component improvement plan system and elevator component improvement plan method

Abstract

The invention provides an elevator component improvement plan system and an elevator component improvement plan method. The system is provided with various databases which manage each component constituting the elevator; an information extraction part which extracts delivery information and maintenance information; an operational part which obtains the number of object components delivered to thesame destination; an analysis processing part which computes the number of faulty object components based on the delivery numbers and failure occurrence information, generates reliability analysis information using a plurality of functions for reliability analysis to implement Weibull analysis, computes the failure replacement timing of the object component, understands the working environment and the manufacturing record of the object component based on maintenance extraction information, working environment information, delivery test data and manufacturing record information of the object component to analyze failure causes, and computes the replacement forecast timing ahead of the failure replacement timing; and a management part which notifies the replacement timing of the object component when operation condition data of the object component collected at any time approach the replacement forecast timing.

Description

technical field [0001] The present invention relates to an elevator component improvement planning system and an elevator component improvement planning method for improving the replacement timing of each component constituting an elevator. Background technique [0002] Elevators installed in buildings etc. are regularly inspected by maintenance personnel in order to prevent accidents and the like. At this time, among the various components constituting the elevator, for example, components that have reached the end of their life due to long-term use are repaired or replaced. [0003] In recent years, as a system for maintenance and inspection of elevators, a system has been known that, in addition to displaying customer data on the destination of each component, displays delivery information such as the operating time of the elevator or displays the status of the components. A system that stores maintenance information, such as failure timing, in a database. The maintenan...

Problems solved by technology

However, in the case of investigating the cause of the failure, the response is delayed because the investigation takes time

[0012] In addition, when the replacement timing is set based on the replacement history of the parts, the time required for parts replacement at the replacement timing or the price of the parts differs depending on the article, and it cannot be handled easily without discrimination.

[0013] In addition, since it is difficult to set the replacement timing of parts, it is difficult to predict the occurrence of failure in advance.

As a result, it is conceivable that there is also a possibility that a part fails before the part is replaced

[0014] In addition, there are cases where the use period of parts is shortened to

In this case, since the cause is unclear, fundamental improvements cannot be made, and parts replacement has to be done.

[0015] In addition, when a defect occurs in a part, it takes time to grasp the number of parts with the same defect

Furthermore, since it is unclear how many replacement parts should be ensured for the occurrence of defective parts, it is conceivable that there may be insufficient replacement parts

[0016] In addition, even if there is no abnormality in the characteristic data (delivery test data) when the parts are shipped, there may be defects in the parts after shipment

In this case, it is impossible to stop the delivery of parts, and it is impossible to prevent problems that occur after delivery.
