在步驟S150中，計劃部213係根據新期限日而決定保養作業日。 In step S150, the planning unit 213 determines a maintenance work day based on the new deadline.

再者，計劃部213係將保養作業日登錄於保養計劃資料120。 In addition, the planning section 213 registers the maintenance work day in the maintenance plan data 120.

茲說明步驟S150的程序。 The procedure of step S150 is described below.

首先，計劃部213係從保養計劃資料120選擇下一次的造訪日。 First, the planning department 213 selects the next visit day from the maintenance plan data 120.

接著，計劃部213係將下一次的造訪日與新期限日進行比較。 Next, the planning department 213 compares the next visit date with the new deadline date.

當下一次的造訪日為較新期限日更之前之日時，計劃部213係將新期限日之前的造訪日決定為保養作業日。具體而言，計劃部213係從保養計劃資料120選擇緊接著新期限日之前的造訪日。所選擇的造訪日即成為保養作業日。再者，計劃部213係將保養作業日登錄於保養計劃資料120。 When the next visit date is a day before the new deadline date, the planning department 213 determines the visit date before the new deadline date as the maintenance operation day. Specifically, the planning department 213 selects a visit date immediately before the new deadline from the maintenance plan data 120. The selected visit day becomes the maintenance work day. In addition, the planning section 213 registers the maintenance work day in the maintenance plan data 120.

當下一次的造訪日為新期限日之後之日時，計劃部213即將較新期限日更之前之追加的造訪日決定為保養作業日。具體而言，計劃部213係選擇至新期限日為止前的任一日。所選擇之日即成為追加的造訪日及保養作業日。再者，計劃部213係將追加的造訪日登錄於保養計劃資料120。再者，計劃部213係將保養作業日登錄於保養計劃資料120。 When the next visit date is a day after the new deadline date, the planning department 213 decides that an additional visit date before the new deadline date is a maintenance work day. Specifically, the planning unit 213 selects any day before the new deadline. The selected day becomes the additional visit day and maintenance work day. In addition, the planning department 213 registers the additional visit day in the maintenance plan data 120. In addition, the planning section 213 registers the maintenance work day in the maintenance plan data 120.

茲根據第8圖及第10圖來說明保養作業日的決定。 The determination of the maintenance work day will be described with reference to FIGS. 8 and 10.

目前係較第2造訪日更之後之日，且為較第3造訪日更之前之日。換言之，下一次的造訪日係第3造訪日。 Currently, it is a date later than the second visit day, and it is a date before the third visit day. In other words, the next visit is the third visit.

在第8圖至第10圖中，係顯示3個容許值。第1容許值係最大的容許值，第2容許值係中間的容許值，第3容許值係最小的容許值。 In FIGS. 8 to 10, three allowable values are shown. The first allowable value is the maximum allowable value, the second allowable value is the intermediate allowable value, and the third allowable value is the smallest allowable value.

在第8圖中，設為由管理者指定了第1容許值。 In FIG. 8, it is assumed that the first allowable value is designated by the manager.

此時，下一次的造訪日(第3造訪日)為較期限日更之前之日，而緊接著期限日之前的造訪日為第4造訪日。因此，計劃部213係將第4造訪日決定為保養作業日。 At this time, the next visit day (the third visit day) is a day before the deadline date, and the visit day immediately before the deadline date is the fourth visit day. Therefore, the planning department 213 decides the fourth visit day as the maintenance work day.

在第9圖中，設為由管理者指定了第2容許值。 In FIG. 9, it is assumed that the second allowable value is designated by the manager.

此時，下一次的造訪日(第3造訪日)為較期限日更之前之日，而緊接著期限日之前的造訪日為第3造訪日。因此，計劃部213係將第3造訪日決定為保養作業日。 At this time, the next visit day (third visit day) is a day before the deadline date, and the visit day immediately before the deadline date is the third visit day. Therefore, the planning department 213 decides the third visit day as the maintenance work day.

在第10圖中，設為由管理者指定了第3容許值。 In FIG. 10, it is assumed that the third allowable value is designated by the manager.

此時，下一次的造訪日(第3造訪日)為較期限日更之後之日。因此，計劃部213係選擇較下一次之造訪日更之前之日作為追加的造訪日，且將追加的造訪日決定為保養作業日。 At this time, the next visit date (third visit date) is a date later than the deadline date. Therefore, the planning department 213 selects a day before the next visit day as the additional visit day, and determines the additional visit day as the maintenance operation day.

＊＊＊實施形態1的補充＊＊＊ *** Supplement to Embodiment 1 ***

監視對象110的具體例係機械設備。 A specific example of the monitored object 110 is a mechanical device.

機械設備係由多種零件所構成，各個零件的劣化係隨著使用次數或經歷年限而進行。因此，為使服務停止等的異常不會發生，乃定期地實施保養作業(檢修、調整及零件更換等)。 Mechanical equipment is composed of various parts, and the deterioration of each part progresses with the number of uses or the age. Therefore, in order to prevent abnormalities such as service suspension, maintenance operations (such as inspection, adjustment, and replacement of parts) are performed regularly.

機械設備的具體例係電梯。 A specific example of the mechanical equipment is an elevator.

茲實施對於電梯的遠端監視。在遠端監視中，經由機體內之感測器111所獲得的感測器資訊被集中於中心設備(center)。當被遠端監視偵測到異常時，保養作業員即出動至現場進行修理。 Remote monitoring of the elevator is implemented. In remote surveillance, via the body The sensor information obtained by the sensor 111 is concentrated in a center. When an abnormality is detected by remote monitoring, the maintenance operator is dispatched to the site for repair.

監視對象110或具有監視對象110之設施的具體例，係工廠(plant)。 A specific example of the monitoring target 110 or a facility having the monitoring target 110 is a plant.

為了制定對於工廠之合理的保養計劃方案，係藉由每一異常項目的影響度與發生頻率的相乘而計算風險。再者，實施基於風險的維修(RBM)。在RBM中，係依據風險而決定保養周期及保養內容。影響度係表示異常發生時的影響。具體而言，影響度係依據對於人命的影響、金錢的損失或因應所需的時間等而求出。發生頻率係表示異常發生的可能性。在一般的RBM中，發生頻率係依據機種的故障發生實績或設計者的真知灼見等而求出。 In order to formulate a reasonable maintenance plan for the factory, the risk is calculated by multiplying the impact of each abnormal item with the frequency of occurrence. Furthermore, implement risk-based maintenance (RBM). In RBM, the maintenance cycle and maintenance content are determined based on risks. The degree of influence indicates the influence when an abnormality occurs. Specifically, the degree of influence is determined based on the effect on human life, loss of money, or time required. The frequency of occurrence indicates the possibility of abnormality. In general RBM, the frequency of occurrence is determined based on the actual failure occurrence of the model or the insights of the designer.

再者，已提出一種藉由解析技術及模擬技術的進步，而預測因為使用所導致之構件之劣化的技術方案。即使模擬困難，亦大多可藉由耐久實驗的實施而預測異常發生的使用次數或使用時間。 Furthermore, a technical solution has been proposed to predict the deterioration of components due to the use of advances in analysis technology and simulation technology. Even if the simulation is difficult, most of them can predict the number of times of use or the time of use of anomalies through the implementation of endurance experiments.

在此，故障的發生頻率係隨著成為故障原因之零件的劣化而增加。因此，當使用藉由劣化預測技術所獲得的推算結果時，可推算特定時序(timing)中之各故障的發生頻率。 Here, the frequency of failures increases with the deterioration of the parts that cause them. Therefore, when the estimation result obtained by the degradation prediction technique is used, the occurrence frequency of each fault in a specific timing can be estimated.

此外，由於當實施保養作業時會改善零件的狀態，因此關於接受保養作業實施之零件之異常的發生頻率會降低。 In addition, since the condition of the parts is improved when maintenance operations are performed, the frequency of occurrence of abnormalities regarding the parts subjected to maintenance operations is reduced.

各異常的影響度即使劣化狀況變化也不會改變。因此，當進行發生頻率與影響度的相乘時，可計算出特定時序中的風險。 The degree of influence of each abnormality does not change even if the deterioration condition changes. Therefore, when the frequency of occurrence and the degree of influence are multiplied, the risk in a specific time series can be calculated.

在此，藉由將導致利用者之傷害之故障的影響度特意設為較通常的故障更高的值，重要零件的劣化將會更大地反映於風險。 Here, by intentionally setting the degree of influence of a failure that causes injury to a user to be higher than a normal failure, the deterioration of important parts will be more reflected in the risk.

保養計劃系統100係設為可供管理者(包含監視對象110的所有者)易於變更成為保養作業之實施基準的容許值。監視對象110的風險值係利用RBM而計算。 The maintenance planning system 100 is an allowable value that can be easily changed by a manager (including the owner of the monitoring target 110) to be a reference for implementing maintenance work. The risk value of the monitored object 110 is calculated using RBM.

首先，在設置監視對象110時，決定初始的容許值(容許位準(level)的初始值)。然後，使用加速實驗的結果或過去的故障實績資料等而進行劣化預測，且根據預測結果而計算風險值時間序列，及根據風險值時間序列而產生初始的保養計劃資料120。 First, when the monitoring target 110 is set, an initial allowable value (an initial value of an allowable level) is determined. Then, the deterioration prediction is performed using the results of the accelerated experiment or past failure performance data, etc., and the risk value time series is calculated based on the prediction results, and the initial maintenance plan data 120 is generated based on the risk value time series.

當作業員以一定周期造訪現場時，保養作業將會在風險值剛要超過容許值之前的定期造訪時實施。除此之外，為使風險值不會超過容許值，而且使作業量最小化，乃訂定定期保養計劃(初始保養計劃)。此時，要考慮保養作業之實施據點中之人員計劃及複數個作業之依存關係等的條件。 When the operator visits the site at a certain period, the maintenance work will be performed at regular visits just before the risk value exceeds the allowable value. In addition, in order to prevent the risk value from exceeding the allowable value and minimize the amount of work, a regular maintenance plan (initial maintenance plan) is established. At this time, consideration must be given to the conditions such as the personnel plan in the maintenance base and the dependency relationship between multiple operations.

在開始監視對象110的運用之後，利用監視對象110所具備的感測器111而實施遠端監視。然後，掌握監視對象110之各零件的劣化狀況。 After the operation of the monitoring target 110 is started, remote monitoring is performed using the sensor 111 provided in the monitoring target 110. Then, the deterioration condition of each component of the monitoring target 110 is grasped.

在此，雖存在從劣化推算所獲得的資料與所觀測到的資料，但在所觀測到的資料中，存在有測量參差不齊。因此，藉由使用卡爾曼濾波法(Kalman filter)之類的手法來組合此2 種資料，可進行精確度更高的劣化推算。至於不進行遠端監視的部位，亦可使用造訪時的檢修結果來進行狀態推算。 Here, although the data obtained from the degradation estimation and the observed data exist, there is a measurement unevenness in the observed data. Therefore, by using a Kalman filter or the like to combine the 2 This kind of data can be used for more accurate estimation of degradation. As for the parts that are not monitored remotely, the status of the visit can be used to estimate the status.

當所有零件的劣化狀況與設置時所預測之劣化狀況的差異為一定範圍內時，不需要進行保養計劃的修正。因此，仍然可繼續運用。 When the difference between the deterioration condition of all parts and the deterioration condition predicted at the time of setting is within a certain range, it is not necessary to modify the maintenance plan. Therefore, it can still be used.

另一方面，當差異超過一定範圍時，保守計劃要進行修正。 On the other hand, when the difference exceeds a certain range, the conservative plan needs to be revised.

作為第1階段的修正，係調整定期保養實施的時序及內容。 As the first stage of revision, the timing and content of regular maintenance implementation were adjusted.

當狀態的劣化比事前預測更快時，變更保養計劃以因應1次前的定期造訪時。此外，當風險值因為劣化而於緊接著保養實施日之前超過了容許值時，亦可以數日單位來調整保養作業的日程。 When the deterioration of the condition is faster than predicted in advance, the maintenance plan is changed to correspond to the previous regular visit. In addition, when the risk value exceeds the allowable value immediately before the maintenance implementation date due to deterioration, the maintenance work schedule can also be adjusted in units of several days.

當狀態的劣化比事前預測更慢時，亦可變更保養計劃以因應1次後的定期造訪時。 When the deterioration of the condition is slower than predicted in advance, the maintenance plan can also be changed to cope with the regular visits after the first visit.

再者，亦可藉由根據與作成初始之保養計劃時相同的限制條件而將保養計劃最佳化，而決定最終之定期保養的實施內容。 Furthermore, the content of the final scheduled maintenance can be determined by optimizing the maintenance plan based on the same constraints as when creating the initial maintenance plan.

當無法藉由第1階段的修正而將風險值的上升控制於容許範圍內時，以實施非定期之保養之方式變更保養計劃。尤其當在風險值達到容許值為止前的時間無餘裕時，以實施緊急出動之方式變更保養計劃。在緊急出動中，作業員係緊急前往現場而進行對於對象部位的保養作業。另一方面，亦可當有時間上的餘裕時，於實施非定期保養之前，以為了實施非定期保養的造訪為前提而將對象機體整體的保養計劃予以最佳化。藉此，即可隨同對於其他部位的保養作業一併進行對於對象部位的保養作業。 When the increase in risk value cannot be controlled within the allowable range through the correction in the first stage, the maintenance plan is changed by implementing non-scheduled maintenance. Especially when there is no time left before the risk value reaches the allowable value, the maintenance plan is changed by implementing emergency dispatch. During the emergency call, the operator rushed to the scene to perform maintenance work on the target site. On the other hand, when there is a margin of time, you can optimize the overall maintenance plan of the target body before performing the non-scheduled maintenance on the premise of a visit for the non-scheduled maintenance. Optimization. Thereby, the maintenance work for the target part can be performed together with the maintenance work for other parts.

另外，當已調整了下一次之後造訪時的作業內容時，保養計劃資料120即被更新，且根據更新後的資料而持續監視狀態變化。藉由在已明確得知無法以此保養計劃完全因應風險的時點修正保養計劃，即可一直遵照此保養計劃系統100而決定最佳的因應方針。 In addition, when the operation content at the time of the next visit has been adjusted, the maintenance plan data 120 is updated, and the status change is continuously monitored based on the updated data. By correcting the maintenance plan at a point when it is clearly known that this maintenance plan cannot fully respond to risks, the maintenance plan system 100 can be always followed to determine the best response policy.

此外，在運用此系統的期間，將會改善劣化預測的精確度。因此，亦可以長期的周期來重估初始的保養計劃本身，以使此改善的效果反映於初始的保養計劃。 In addition, the accuracy of the degradation prediction will be improved during the application of this system. Therefore, the initial maintenance plan itself can be re-evaluated over a long period of time, so that the effect of this improvement is reflected in the initial maintenance plan.

風險的容許值係以依據管理者的期望來設定為理想。 The allowable value of risk is ideally set in accordance with managers' expectations.

例如，在高級旅館(hotel)中，係要求噪音及振動要維持在極低的水準。此外，在醫療機構中，則要求要極短的停機時間。 For example, in high-end hotels, noise and vibration are required to be maintained at extremely low levels. In addition, in medical facilities, extremely short downtime is required.

在此種情形下，藉由將容許值設為較通常更低，即可制定出反映出期望之最佳的保養計劃方案。惟，即使以此方式調整容許值時，也不可能容許對於會發生對利用者人體造成影響之故障之類的水準的調整。 In this case, by setting the allowable value lower than usual, an optimal maintenance plan that reflects expectations can be formulated. However, even when the allowable value is adjusted in this manner, it is impossible to allow adjustment of a level such as a failure that affects the human body of the user.

風險值係除了保養服務公司在作成保養計劃時被活用外，還會被管理者實時(realtime)地揭示，故而被有效地活用。 The risk value is used in addition to the maintenance service company in making a maintenance plan, and it is also revealed in real time by the manager, so it is effectively used.

保養計劃系統100係包括管理終端300。管理終端300係可設於運用著保養計劃系統100的中心設備設施，亦可設置於藉由網路101所連接的遠端地。 The maintenance planning system 100 includes a management terminal 300. The management terminal 300 may be installed at a central facility using the maintenance planning system 100, or may be installed at The remote ground connected through the network 101.

管理者係可使用管理終端300而確認保養服務公司一面管理機體的風險一面適當地實施保養作業一事。再者，管理者係可根據關於適當之容許值的檢討結果，而立即地變更容許值。 The manager can use the management terminal 300 to confirm that the maintenance service company appropriately performs maintenance work while managing the risk of the body. Furthermore, the manager can change the allowable value immediately based on the result of the review of the appropriate allowable value.

當管理者變更了容許值時，使用現狀之風險值的預測，而再度計算保養計劃。當風險值已超過了新的容許值時，或者，當預測到至下一次定期造訪為止前風險值將會超過新的容許值時，保養計劃系統100即計劃非定期的保養。藉此，即可迅速地對應管理者的期望。 When the manager changes the allowable value, the current risk value forecast is used to calculate the maintenance plan again. When the risk value has exceeded the new allowable value, or when it is predicted that the risk value will exceed the new allowable value until the next regular visit, the maintenance planning system 100 plans non-scheduled maintenance. With this, you can quickly respond to the expectations of managers.

＊＊＊實施形態1的效果＊＊＊ ** Effect of Embodiment 1 **

為了使保養計劃系統100提供調整畫面130給管理者，管理者可適當調整容許值。結果，將可提供管理者所期望的保養服務。因此，可提升顧客滿足度。 In order for the maintenance planning system 100 to provide an adjustment screen 130 to the manager, the manager may appropriately adjust the allowable value. As a result, maintenance services expected by managers will be provided. Therefore, customer satisfaction can be improved.

＊＊＊其他構成＊＊＊ *** Other constructions **

保養計劃系統100(例如保養計劃裝置200)亦可包括產生初始之保養計劃資料120的產生部。此產生部係根據過去的風險值時間序列而預測未來的風險值時間序列，且根據未來的風險值時間序列而產生保養計劃資料120。風險值的預測及保養計劃資料120的產生，係可利用習知之基於風險的維修中的方法。 The maintenance planning system 100 (for example, the maintenance planning device 200) may further include a generating unit that generates initial maintenance planning data 120. This generating unit predicts future risk value time series based on past risk value time series, and generates maintenance plan data 120 based on future risk value time series. The prediction of the risk value and the generation of the maintenance plan data 120 are based on the conventional method in risk-based maintenance.

限制畫面140係具有限制介面141。 The restriction screen 140 includes a restriction interface 141.

限制介面141係用以指定對於監視對象110之動作限制的介面。在限制介面141中，係包含用以指定推薦之動作限制的介面。 The restriction interface 141 is an interface for specifying a restriction on the movement of the monitored object 110. The restriction interface 141 includes an interface for specifying a recommended action restriction.

具體而言，限制介面141係依動作限制的每一種類而具有核取方塊(checkbox)。 Specifically, the restriction interface 141 has a checkbox for each type of operation restriction.

返回第12圖來說明步驟S201的程序。 Returning to Fig. 12, the procedure of step S201 will be described.

首先，畫面部211係產生限制畫面140的資料。 First, the screen section 211 generates data for limiting the screen 140.

接著，通訊部292係將限制畫面140的資料傳送至管理終端300。 Next, the communication unit 292 transmits the data of the restricted screen 140 to the management terminal 300.

接著，通訊部392係從保養計劃裝置200接收限制畫面140的資料。 Next, the communication unit 392 receives the data of the restriction screen 140 from the maintenance planning device 200.

再者，顯示部393係使用限制畫面140的資料而將限制畫面140顯示於顯示器。 The display unit 393 displays the restriction screen 140 on the display using the data of the restriction screen 140.

在步驟S202中，接受部394係接受指定動作限制。 In step S202, the acceptance unit 394 accepts the designated operation restriction.

指定動作限制係被限制畫面140之限制介面141所指定的動作限制。 The designated motion restriction is a motion restriction designated by the restriction interface 141 of the restriction screen 140.

茲說明步驟S202的程序。 The procedure of step S202 will be described.

首先，管理者係藉由管理終端300的輸入裝置，利用限制介面141而指定動作限制。具體而言，管理者係藉由操作滑鼠，而將核取輸入於任一個動作限制的核取方塊。 First, the manager specifies an operation restriction using the input interface of the management terminal 300 using the restriction interface 141. Specifically, the manager inputs the check into any check box of the operation restriction by operating the mouse.

再者，接受部394係接受指定動作限制。 In addition, the acceptance unit 394 accepts a specified operation restriction.

再者，通訊部392係將指定動作限制的通知傳送至保養計劃裝置200。 In addition, the communication unit 392 transmits a notification to specify the operation restriction to the maintenance planning device 200.

接著，通訊部292係從管理終端300接收指定動作限制的通知。 Next, the communication unit 292 receives a notification specifying the operation restriction from the management terminal 300.

然後，記憶部291係記憶指定動作限制。 Then, the memory unit 291 memorizes the designated operation restriction.

在步驟S211中，顯示部393係將調整畫面130顯示於顯示器。 In step S211, the display unit 393 displays the adjustment screen 130 on the display.

步驟S211係與實施形態1中的步驟S110(參照第5圖)相同。 Step S211 is the same as step S110 (refer to FIG. 5) in the first embodiment.

在步驟S212中，接受部394係接受指定容許值。 In step S212, the acceptance unit 394 accepts the specified allowable value.

步驟S212係與實施形態1中的步驟S120(參照第5圖)相同。 Step S212 is the same as step S120 (see FIG. 5) in the first embodiment.

在步驟S213中，調整部212係算出新期限日。 In step S213, the adjustment unit 212 calculates a new deadline date.

步驟S213係與實施形態1中的步驟S130(參照第5圖) 相同。 Step S213 is the same as step S130 in the first embodiment (see FIG. 5). the same.

在步驟S220中，限制部214係從保養計劃資料120選擇下一次的造訪日。 In step S220, the restriction unit 214 selects the next visit day from the maintenance plan data 120.

再者，限制部214係將下一次的造訪日與新期限日進行比較。 The restriction unit 214 compares the next visit date with the new deadline date.

當下一次的造訪日為較新期限日更之前之日時，處理前進至步驟S221及步驟S222。 When the next visit date is a day before the new deadline date, the process proceeds to steps S221 and S222.

當下一次的造訪日為新期限日之後之日時，處理前進至步驟S231(參照第13圖)。 When the next visit date is a day after the new deadline date, the process proceeds to step S231 (see FIG. 13).

在步驟S221中，畫面部211係更新調整畫面130。 In step S221, the screen section 211 updates the adjustment screen 130.

更新方法係與實施形態1中的步驟S140(參照第5圖)相同。 The update method is the same as step S140 (see FIG. 5) in the first embodiment.

在步驟S222中，計劃部213係將新期限日之前的造訪日決定為保養作業日。具體而言，計劃部213係從保養計劃資料120選擇緊接著新期限日之前的造訪日。所選擇的造訪日即成為保養作業日。 In step S222, the planning unit 213 determines the visit day before the new deadline as the maintenance work day. Specifically, the planning department 213 selects a visit date immediately before the new deadline from the maintenance plan data 120. The selected visit day becomes the maintenance work day.

在步驟S231(參照第13圖)中，限制部214係限制監視對象110的動作。 In step S231 (see FIG. 13), the restriction unit 214 restricts the operation of the monitoring target 110.

具體而言，限制部214係產生對應指定動作限制的動作命令。 Specifically, the restriction unit 214 generates an operation command corresponding to a specified operation restriction.

再者，通訊部292係將所產生的動作命令傳送至監視對象110。 The communication unit 292 transmits the generated operation command to the monitoring target 110.

監視對象110係接收動作命令，且依照所接收的動作命令而動作。 The monitoring target 110 receives an operation command and operates in accordance with the received operation command.

藉此，限制監視對象110的動作。 Thereby, the operation of the monitoring target 110 is restricted.

在步驟S232中，預測部215係算出限制後的風險值時間序列。 In step S232, the prediction unit 215 calculates the time series of the risk value after the limitation.

限制後的風險值時間序列係監視對象110之動作被限制之後的風險值時間序列。 The restricted risk value time series is a risk value time series after the operation of the monitoring object 110 is restricted.

具體而言，預測部215係根據監視對象110之限制後的動作與監視對象110之過去的風險值時間序列，而算出監視對象110之未來的風險值時間序列。 Specifically, the prediction unit 215 calculates the future risk value time series of the monitoring target 110 based on the restricted operation of the monitoring target 110 and the past risk value time series of the monitoring target 110.

風險值時間序列的算出，係可利用習知之基於風險的維修中的算出方法。 The calculation of the time series of the risk value can be performed by a conventional calculation method based on risk.

在步驟S233中，調整部212係算出限制後的期限日。 In step S233, the adjustment unit 212 calculates a deadline date after the restriction.

期限後的期限日，係在監視對象110的動作被限制之後對應指定容許值的期限日。 The deadline date after the deadline is a deadline date corresponding to the specified allowable value after the operation of the monitoring target 110 is restricted.

具體而言，調整部212係根據指定容許值與限制後的風險值時間序列而算出限制後的期限日。限制後的期限日係風險值達到指定容許值之日。換言之，限制後的期限日，係對應與指定容許值相同值的風險值之日。此外，記憶部291係將所記憶的期限日更新為限制後的期限日。 Specifically, the adjustment unit 212 calculates the limit date after the restriction based on the time series of the specified allowable value and the restricted risk value. The limit date is the day when the risk value reaches the specified allowable value. In other words, the limit date is the date corresponding to the risk value equal to the specified allowable value. The memory unit 291 updates the memorized deadline date to the restricted deadline date.

在步驟S234中，畫面部211係更新調整畫面130。 In step S234, the screen section 211 updates the adjustment screen 130.

具體而言，畫面部211係根據指定容許值而移動調整畫面130的容許標記132，且根據限制後的期限日而移動調整畫面 130的期限標記133。 Specifically, the screen section 211 moves the adjustment mark 132 of the adjustment screen 130 according to the specified allowable value, and moves the adjustment screen according to the limit date and time. Term mark 130 and 133.

步驟S234的程序係與實施形態1中的步驟S140(參照第5圖)的程序相同。 The procedure of step S234 is the same as that of step S140 (see FIG. 5) in the first embodiment.

在步驟S235中，計劃部213係根據限制後的期限日而決定保養作業日。 In step S235, the planning unit 213 determines a maintenance work day based on the restricted deadline.

步驟S235的程序係與實施形態1中的步驟S150(參照第5圖)的程序相同。 The procedure of step S235 is the same as that of step S150 (see FIG. 5) in the first embodiment.

茲根據第15圖及第16圖來說明保養作業日的決定。 The determination of the maintenance work day will be described with reference to FIGS. 15 and 16.

在第15圖中，風險曲線圖係表示監視對象110之動作被限制之前的風險值時間序列。 In FIG. 15, the risk curve diagram shows a time series of risk values before the operation of the monitoring target 110 is restricted.

下一次的造訪日(第3造訪日)係較期限日更之後之日。因此，監視對象110的動作被限制。 The next visit day (third visit day) is a day after the deadline date. Therefore, the operation of the monitoring target 110 is restricted.

在第16圖中，風險曲線圖係表示監視對象110之動作被限制之後的風險值時間序列。由於監視對象110的動作被限制，因此風險值的上升被抑制。 In FIG. 16, the risk graph is a time series of risk values after the operation of the monitoring target 110 is restricted. Since the operation of the monitoring target 110 is restricted, an increase in the risk value is suppressed.

下一次的造訪日(第3造訪日)係較期限日更之前之日，緊接著期限日之前的造訪日係第3造訪日。因此，計劃部213係將第3造訪日決定為保養作業日。 The next visit day (third visit day) is a day before the deadline date, and the visit date immediately before the deadline date is the third visit day. Therefore, the planning department 213 decides the third visit day as the maintenance work day.

＊＊＊實施形態2的補充＊＊＊ ** Supplement of Embodiment 2 ***

當僅以所計劃之造訪時之作業內容的修正而難以將風險值的上升控制於容許值以下時，限制監視對象110之動作的一部分，以取代實施非定期保養。大部分的構件都會隨著使用次數而逐漸劣化。因此，可藉由限制使用次數來抑制劣化的進行。限制部214係以下一次造訪日之風險值未達容許值之方式決定動作限制的位準。當僅以動作限制而無法抑制風險值時，計劃部213係將追加的造訪日決定為保養作業日。 When it is difficult to control the increase of the risk value below the allowable value only by the modification of the operation content at the time of the planned visit, a part of the operation of the monitoring target 110 is restricted to replace the non-scheduled maintenance. Most components will gradually deteriorate with the number of uses. Therefore, the progress of deterioration can be suppressed by limiting the number of uses. The restriction unit 214 determines the level of the operation restriction in such a manner that the risk value on the next visit date does not reach the allowable value. When the risk value cannot be suppressed only by the operation limitation, the planning department 213 determines the additional visit day as the maintenance work day.

指定動作限制的內容係預先決定而登錄於記憶部291。動作限制的內容係可顯示於管理終端300的顯示器。再者，動作限制的實施狀況係可顯示於管理終端300的顯示器。再者，管理者係可在限制畫面140變更動作限制的內容。 The contents of the designated operation restriction are determined in advance and registered in the storage unit 291. The content of the motion restriction can be displayed on the display of the management terminal 300. It should be noted that the implementation status of the motion restriction can be displayed on the display of the management terminal 300. In addition, the manager can change the content of the operation restriction on the restriction screen 140.

當動作限制的內容被變更時，預測部215係重新算出風險值時間序列。當推算出風險值會超過容許值時，與未實施動作限制的情形同樣地，計劃部213係以實施非定期保養之方式訂定保養計劃。 When the content of the operation restriction is changed, the prediction unit 215 recalculates the time series of the risk value. When the risk value is estimated to exceed the allowable value, the planning section 213 establishes a maintenance plan by performing non-scheduled maintenance in the same manner as when the operation limit is not implemented.

動作限制係可以裝置整體為對象，亦可限定於與劣化進行中的構件直接相關的範圍。 The motion limitation system may be applied to the entire device, or may be limited to a range directly related to a component undergoing degradation.

例如，亦可當電梯的特定搭乘樓門發生了劣化時，限制在該樓層之電梯的利用次數。 For example, when the specific boarding door of the elevator is degraded, the number of times the elevator is used on that floor may be limited.

此外，亦可當發生了電梯之驅動機構相關的劣化時，使電梯廂的動作速度降低，或亦可藉由使規定人數偵測部的設定變化，而使電梯廂動作以限制乘客數。 In addition, when the deterioration of the driving mechanism of the elevator occurs, the operating speed of the elevator car can be reduced, or the elevator car can be operated to limit the number of passengers by changing the setting of the predetermined number of people detection unit.

此外，亦可當發生了搭乘樓門的劣化時，在開門時及關門時降低門的動作速度或啟動加速度。 In addition, when the deterioration of the boarding door occurs, the operating speed or starting acceleration of the door can be reduced when the door is opened and closed.

此外，亦可當升降路徑的一部分發生了劣化時，限定於電梯廂通過劣化部分時而降低電梯廂的速度。 In addition, when a part of the lift path is deteriorated, the speed of the elevator car may be reduced when the elevator car passes the deteriorated part.

管理者係可選擇推薦項目(推薦的動作限制)。推薦項目係影響較小的項目，且以通常的使用模式作為參考來選定。 The manager can select recommended items (recommended action restrictions). The recommended items are those with less influence, and are selected based on the usual usage patterns.

亦可在應用所選擇的動作限制之前設置確認步驟。在確認步驟中，顯示部393係將從保養計劃裝置200所通知之限制後的風險值時間序列及下一次的保養作業日結果顯示於顯示器。管理者係在確認該顯示之後，決定要應用的動作限制。再者，在決定了要應用的動作限制之後，限制部214係限制監視對象110的動作。 It is also possible to set a confirmation step before applying the selected motion limitation. In the confirmation step, the display unit 393 displays the risk value time series after the limit notified from the maintenance planning device 200 and the result of the next maintenance work day on the display. After confirming the display, the manager decides the motion restriction to be applied. After determining the operation restriction to be applied, the restriction unit 214 restricts the operation of the monitoring target 110.

在應用了動作限制時，限制部214亦可將所應用之動作限制的內容通知監視對象110的利用者。 When the operation restriction is applied, the restriction unit 214 may notify the user of the monitoring target 110 of the content of the applied operation restriction.

當監視對象110為電梯時，訊息可顯示於電梯廂內的顯示器，郵件(mail)可傳送給預先登錄的郵件收件人(mail address)，訊息可顯示於設置於搭乘樓門周邊的廣告用顯示器。 When the monitored object 110 is an elevator, the message can be displayed on the display in the elevator car, and the mail can be transmitted to the pre-registered mail address, and the message can be displayed on the advertisement set around the door of the boarding. monitor.

＊＊＊實施形態2的效果＊＊＊ ** Effect of Embodiment 2 **

即使下一次的造訪日為較新期限日更之後之日時，亦可不追加造訪日而將任一天的造訪日設為保養作業日。 Even if the next visit date is later than the new deadline date, the visit day of any day can be set as the maintenance work day without adding the visit date.

(實施形態3) (Embodiment 3)

茲針對所提議之推薦之動作限制的形態，根據第17圖來說明主要與實施形態1及實施形態2不同之點。 Regarding the form of the proposed recommended operation restriction, the points that are mainly different from Embodiment 1 and Embodiment 2 will be described with reference to FIG. 17.

＊＊＊構成的說明＊＊＊ *** Explanation of composition ***

保養計劃系統100的構成係與實施形態1中的構成(參照第1圖)相同。 The configuration of the maintenance planning system 100 is the same as that in Embodiment 1 (see (Figure 1) Same.

茲根據第17圖來說明保養計劃裝置200的構成。 The configuration of the maintenance planning device 200 will be described with reference to FIG. 17.

保養計劃裝置200係進一步包括推薦部216。 The maintenance planning device 200 further includes a recommendation unit 216.

保養計劃程式係進一步使電腦發揮作為推薦部216的功能。 The maintenance plan program further causes the computer to function as the recommendation unit 216.

＊＊＊動作的說明＊＊＊ *** Explanation of operation ***

推薦部216係預先決定推薦的動作限制。 The recommendation unit 216 determines a recommended operation limit in advance.

具體而言，推薦部216係根據監視對象110的動作歷程而決定推薦的動作限制。 Specifically, the recommendation unit 216 determines a recommended operation limit based on the operation history of the monitoring target 110.

監視對象110的動作歷程係顯示監視對象110之過去之動作狀況的資料，被預先記憶於記憶部291。 The operation history of the monitoring target 110 is data that shows the past operation status of the monitoring target 110 and is stored in the storage unit 291 in advance.

當管理者設定動作限制的容許範圍時，難以明確地指定容許範圍。 When the manager sets the allowable range of the operation limit, it is difficult to specify the allowable range explicitly.

因此，推薦部216即根據監視對象110的動作歷程而決定推薦的動作限制。 Therefore, the recommendation unit 216 determines a recommended operation limit based on the operation history of the monitoring target 110.

例如，當監視對象110為電梯時，推薦部216係求出每一時段或每一樓層的利用頻率。再者，推薦部216係選擇影響較少的時段或樓層作為限制對象，且將限制對象中的利用限制或速度限制決定為推薦的動作限制。推薦部216係可根據顯示各大樓之資訊的大樓資料而選擇用途或階層數等與具有監視對象110之電梯的大樓相似的大樓，且根據評估所選擇之大樓中之電梯之動作限制之效果而得的資料而決定推薦的動作限制。換言之，推薦部216係可依據以前在相似的大樓實施動作限制時的影響而決定推薦的動作限制。 For example, when the monitoring target 110 is an elevator, the recommendation unit 216 obtains the use frequency of each time period or each floor. Further, the recommendation unit 216 selects a time period or a floor with less influence as the restriction target, and determines the use restriction or speed restriction among the restriction targets as the recommended motion restriction. The recommendation unit 216 can select a building similar to the building having the elevator with the monitoring target 110 based on the building data displaying the information of each building, and evaluates the effect of the elevator movement restriction on the selected building. The information obtained determines the recommended action limits. In other words, the recommendation unit 216 can determine the recommended operation restriction based on the influence of the previous operation restriction in a similar building.

＊＊＊實施形態3的效果＊＊＊ **** Effect of Embodiment 3 **

由於在保養計劃系統100中決定推薦的動作限制，因此管理者可在限制畫面140選擇推薦的動作限制，藉此而適當地限制監視對象110的動作。 Since the recommended action restriction is determined in the maintenance planning system 100, the manager can select the recommended action restriction on the restriction screen 140, thereby appropriately restricting the action of the monitoring target 110.

(實施形態4) (Embodiment 4)

茲針對當發生了如大規模災害的事件時適當變更保養計劃的形態，根據第18圖至第20圖來說明主要與實施形態1不同之點。 Regarding the form of appropriately changing the maintenance plan when an event such as a large-scale disaster occurs, the main differences from Embodiment 1 will be described with reference to FIGS. 18 to 20.

＊＊＊構成的說明＊＊＊ *** Explanation of composition ***

保養計劃系統100的構成係與實施形態1中的構成(參照第1圖)相同。 The configuration of the maintenance planning system 100 is the same as that in the first embodiment (see FIG. 1).

茲根據第18圖來說明保養計劃裝置200的構成。 The configuration of the maintenance planning device 200 will be described with reference to FIG. 18.

保養計劃裝置200係進一步包括事件部217。 The maintenance planning device 200 further includes an event unit 217.

保養計劃程式係進一步使電腦發揮作為事件部217的功能。 The maintenance plan program further causes the computer to function as the event unit 217.

＊＊＊動作的說明＊＊＊ *** Explanation of operation ***

茲根據第19圖來說明事件對應方法。 An event correspondence method will be described with reference to FIG. 19.

事件對應方法係保養計劃方法的一部分。 The incident response method is part of the maintenance planning method.

在步驟S410中，事件部217係判定是否發生了特定事件。 In step S410, the event unit 217 determines whether a specific event has occurred.

特定事件係需要變更容許值的事件，換言之，係需要變更保養計劃的事件。具體的特定事件係大規模災害。 The specific event is an event in which an allowable value needs to be changed, in other words, an event in which a maintenance plan needs to be changed. Specific specific events are large-scale disasters.

特定事件的發生，係藉由人或感測器而檢測出。 The occurrence of a specific event is detected by a person or a sensor.

當檢測出特定事件的發生時，發生通知即被輸入於保養計劃裝置200。 When a specific event is detected, a notification of the occurrence is entered in the maintenance plan Planning device 200.

再者，當發生通知被輸入於保養計劃裝置200時，事件部217係判定為已發生了特定事件。 When an occurrence notification is input to the maintenance planning device 200, the event unit 217 determines that a specific event has occurred.

當發生了特定事件時，處理前進至步驟S420。 When a specific event has occurred, the process proceeds to step S420.

當未發生特定事件時，處理結束。 When no specific event occurs, the process ends.

在步驟S420中，調整部212係算出事件期限日。 In step S420, the adjustment unit 212 calculates the event deadline date.

事件期限日係對應事件容許值的期限日。 The event deadline date is the deadline date corresponding to the event allowable value.

事件容許值係發生了特定事件時所使用的容許值。 Event tolerance is the tolerance used when a specific event occurs.

具體而言，係容許值的設定範圍預先記憶於記憶部291。 Specifically, the setting range of the allowable value is stored in the storage unit 291 in advance.

再者，調整部212係從設定範圍選擇上限容許值，且根據上限容許值與風險值時間序列而算出事件期限日。事件期限日係風險值達到上限容許值之日。換言之，事件期限日係對應與上限容許值相同之值的風險值之日。此外，記憶部291係將所記憶的容許值更新為上限容許值，且將所記憶的期限日更新為事件期限日。 In addition, the adjustment unit 212 selects an upper limit allowable value from the setting range, and calculates an event deadline date based on the upper limit allowable value and the risk value time series. The event deadline date is the day when the risk value reaches the upper allowable value. In other words, the event deadline date is the date corresponding to the risk value of the same value as the upper limit allowable value. In addition, the storage unit 291 updates the stored allowable value to the upper limit allowable value, and updates the stored deadline date to the event deadline date.

在步驟S430中，計劃部213係根據事件期限日而決定新保養作業日。 In step S430, the planning unit 213 determines a new maintenance work day based on the event deadline.

再者，計劃部213係將登錄於保養計劃資料120的保養作業日變更為新保養作業日。 The planning unit 213 changes the maintenance work day registered in the maintenance plan data 120 to a new maintenance work day.

決定新保養作業日的程序，係與在實施形態1的步驟S150(參照第5圖)中決定保養作業日的程序相同。 The procedure for determining a new maintenance work day is the same as the procedure for determining a maintenance work day in step S150 (see FIG. 5) of the first embodiment.

＊＊＊實施形態4的補充＊＊＊ *** Supplement to Embodiment 4 ***

當發生了大規模災害時，由於會發生大量例如復原作業的緊急作業，因此預期人員資源將會不足。 When a large-scale disaster occurs, due to Urgent operations, so human resources are expected to be insufficient.

另一方面，管理者係抱持著即使發生了大規模災害時也盡可能地想要使用設備的期望。 On the other hand, managers have an expectation that they want to use the equipment as much as possible even in the event of a large-scale disaster.

因此，當發生了大規模災害時，調整部212係自動地提高容許值。惟，調整部212係使提高後的容許值與通常時所可設定之容許值的上限一致。換言之，僅在容許值被設定為較低時才提高容許值。 Therefore, when a large-scale disaster occurs, the adjustment unit 212 automatically increases the allowable value. However, the adjustment unit 212 matches the allowable value after the increase with the upper limit of the allowable value that can be set normally. In other words, the allowable value is increased only when the allowable value is set to be low.

藉此，既可優先進行緊急對應，又可抑制保養作業的增加。 Thereby, emergency response can be performed in priority, and an increase in maintenance work can be suppressed.

緊急時要提高容許值乙事，係預先向管理者提示。例如，顯示部393係將顯示適用條件及變動範圍的通知畫面顯示於顯示器。 In case of emergency, it is necessary to increase the allowable value, which is to be notified to the manager in advance. For example, the display unit 393 displays a notification screen displaying the applicable conditions and the range of variation on a display.

視監視對象110的用途而定，即使緊急時亦會被要求優先性的保養作業。例如，關於醫療機構的裝置，即使緊急時亦會被要求優先性的保養作業。 Depending on the purpose of the monitoring target 110, priority maintenance work may be required even in an emergency. For example, regarding a medical facility's equipment, priority maintenance work is required even in an emergency.

針對此種監視對象110，亦可設定為不要進行容許值的提高。 The monitoring target 110 may be set such that the allowable value is not increased.

此外，亦可設定為依照災害的規模而變化容許值的上升幅度。例如，從災害規模與容許值彼此建立對應關係的表單(table)選擇對應災害規模的容許值。 It is also possible to set a rise in the allowable value that varies according to the scale of the disaster. For example, the tolerance value corresponding to the disaster scale is selected from a table in which the disaster scale and the tolerance value correspond to each other.
