大きな開きが出る可能性が高く、保全コストが正確に把
握できないという問題がある。By the way, the life expectancy value of a component is obtained from the operating item that most affects the life of the component, for example, the design life value represented by the operating time, the production amount, the number of shots or the past performance. Since it is calculated in days, months or years based on the measured actual life value and the operating frequency measurement value of the customer, it should be different depending on the customer, but since the operating frequency of the customer is not known when delivering the equipment, maintenance It is difficult to accurately calculate the life expectancy of parts that is the basis of long-term maintenance plans required for cost calculation or maintenance contracts. In the preventive maintenance system according to the conventional example, the life expectancy of the parts at the time of delivery of the equipment is uniformly used for all the customers by using one operation frequency average value obtained from the past results. There is a possibility that there will be a big difference between the replacement plan and the replacement plan after operation, and there is a problem that the maintenance cost cannot be accurately grasped.

いう問題がある。Further, in the preventive maintenance system according to the conventional example, the replacement time of parts is set to the same timing with respect to the life expectancy value for all customers, and differentiation is made by contract contents such as maintenance fee. Since there is no such service, there is a problem that a service according to the contract content cannot be provided to the customer.

問題もある。In addition, in the preventive maintenance system according to the above-mentioned conventional example, it is necessary to convert the operation measurement value into the operation time, and to convert it twice in order to make a replacement plan based on the number of days, months or years. There is also a problem that the accuracy of does not improve.

予防保全周期を設定できないという問題がある。Further, in the preventive maintenance system according to the above-mentioned conventional example, since the operation measured value for each part cannot be obtained in equipment other than the microcomputer type, that is, in equipment where the operation measured value cannot be measured, this preventive maintenance system is There is a problem that it cannot be applied and the optimum preventive maintenance cycle cannot be set.

に提供することができる。As described above, when the elevator is delivered, the operating frequency necessary for predicting the service life for each customer is not set to a uniform average value, but the designed service life value or the actual service life value stored in the component information storage unit. When the life prediction is performed for each customer from the operation frequency reference value for each customer specification obtained from the past record stored in the customer information storage unit, the life prediction value more suited to the operation state of the customer can be obtained. By minimizing the difference between the life expectancy value and the preventive maintenance plan when the elevator is delivered and after operation, the maintenance cost can be accurately grasped at the time of delivery. Moreover, since the parts replacement timing with respect to the life expectancy value can be adjusted according to the contract content, it is possible to provide the service according to the contract content to the customer.

寿命の予測を行うという構成にした。In order to solve the above-mentioned problems, the present invention thirdly, in the case of an elevator in which the operation measurement value cannot be measured for each component, the customer-specific component life predicting means sets the component after the elevator is in operation. The design life value or actual life value stored in the information storage unit and the elevator operating time stored in the customer information storage unit are obtained from the similar parts record of the elevator that can measure the operation measurement value for each part. The operation frequency reference value for each customer specification is used to obtain an operation frequency conversion value converted into the operation frequency measurement value, and the service life is predicted for each customer using the operation frequency conversion value.

る。As described above, for an elevator whose operation measurement value for each component cannot be measured, the operation frequency required for life prediction is not set to a uniform average value, but an elevator that can measure the operation measurement value is used. If you select and use a value that meets customer specifications from the operation frequency reference values that are categorized by customer specifications obtained from the results of similar parts, you can predict the service life that is closer to the actual operating condition. An optimal preventive maintenance cycle can be set even for elevators whose values cannot be measured.

確立することができる。As described above, when the parts are shipped and the repair and replacement work is performed according to the plan obtained by the customer-specific replacement cycle planning means, the preventive replacement can be performed before the failure.
The occurrence of downtime can be suppressed, and the operating rate of the elevator can be increased. In addition, by investigating the parts collected by preventive replacement, it is possible to replace, collect, and investigate a fixed amount of parts more efficiently and systematically than the failed parts, so it is possible to obtain the actual life value. , It is possible to improve the operation rate of elevators and establish preventive maintenance for new parts at an early stage.

選択して、部品交換計画を立てる。First, in step S1, it is determined whether or not a predetermined elapsed time after delivery of the elevator has been reached. If it is determined that the predetermined elapsed time has not been reached, the process proceeds to step S2, From the customer-specific operation frequency reference value obtained from the past results stored in the operation information table 6, the customer specifications stored in the customer specification table 6, for example, the past results illustrated in FIG. Select a customer specification pattern having an operating frequency reference value. In other words, during the few months immediately after the elevator is delivered, usually only luggage is loaded onto each floor, trial run, etc., and the operating status of the elevator parts such as the number of operating times, operating time, and monthly average running time is unstable. Therefore, when a parts replacement plan is made during such an unstable operation period, the operation frequency measurement value for each customer required for the customer-specific life prediction varies, and an accurate parts replacement plan cannot be made. Therefore, when a predetermined elapsed time after the elevator is delivered is set in advance and a parts replacement plan is made before the predetermined elapsed time is passed, it is obtained from the past results stored in the operation information table 6. Select an operating frequency reference value for each customer and make a parts replacement plan.
