如第2圖所示,控制裝置18,例如備置運轉控制部30(運轉控制手段)、測量部31(測量手段)以及溫度取得部32(取得手段)。以下,參照第3及4圖,說明關於控制裝置18備置的機能。第3圖係顯示控制裝置18的動作例之流程圖。 As shown in FIG. 2, the control apparatus 18 is equipped with the operation control part 30 (operation control means), the measurement part 31 (measurement means), and the temperature acquisition part 32 (acquisition means), for example. Hereinafter, with reference to FIGS. 3 and 4 , the functions provided in the control device 18 will be described. FIG. 3 is a flowchart showing an example of the operation of the control device 18 .

根據控制裝置18,判定開始條件是否成立(S101)。開始條件,係用以開始診斷運轉的條件。預先設定開始條件。不成立開始條件的話,運轉控制部30,例如控制通常運轉。通常運轉中,運轉控制部30,依序使車廂10應對登錄的呼叫。 According to the control device 18, it is determined whether or not the start condition is satisfied (S101). The start condition is a condition for starting the diagnostic operation. Start conditions are set in advance. If the start condition is not satisfied, the operation control unit 30 controls the normal operation, for example. During normal operation, the operation control unit 30 sequentially causes the cars 10 to respond to the registered calls.

例如,定期進行診斷運轉。例如,到了每月10日的上午10點時,開始條件成立。作為其他例,不定期進行診斷運轉。例如,通訊裝置26從外部接收確定的信號時,開始條件成立。開始條件成立時,運轉控制部30開始診斷運轉(S102)。進行診斷運轉,用以判定升降梯1內備置的機器是否有異常。 For example, a diagnostic operation is performed periodically. For example, at 10:00 am on the 10th of each month, the start condition is satisfied. As another example, the diagnostic operation is performed irregularly. For example, when the communication device 26 receives a specific signal from the outside, the start condition is satisfied. When the start condition is satisfied, the operation control unit 30 starts the diagnostic operation ( S102 ). A diagnostic operation is performed to determine whether or not the equipment built in the elevator 1 is abnormal.

運轉控制部30,例如,診斷運轉中使用確定的機器,使車廂10進行確定的動作。測量部31,測量診斷運轉中測量確定的值(S103)。例如,測量部31,測量關於車廂10的動作的值或關於上述機器的值。測量部31計量的值,使用於判定有無異常。 The operation control unit 30 , for example, uses the specified device during the diagnostic operation, and causes the vehicle 10 to perform the specified operation. The measurement unit 31 measures the value determined by the measurement during the diagnostic operation (S103). For example, the measurement unit 31 measures a value related to the operation of the vehicle compartment 10 or a value related to the above-mentioned equipment. The value measured by the measuring unit 31 is used to determine the presence or absence of abnormality.

例如,運轉控制部30,在診斷運轉中使用電池25使車廂10進行確定的動作。例如,運轉控制部30,利用來自電池25的電力,使車廂10進行確定 的行駛。診斷運轉中,進行上述確定的行駛期間,以測量部31測量電池25的電壓值。測量部31測量的電池25的最小電壓值Vmin低於基準值時,判定異常。 For example, the operation control unit 30 uses the battery 25 in the diagnostic operation to cause the vehicle 10 to perform a specific operation. For example, the operation control unit 30 uses the electric power from the battery 25 to determine the vehicle 10 of driving. During the diagnostic operation, the voltage value of the battery 25 is measured by the measurement unit 31 during the specified running period. When the minimum voltage value Vmin of the battery 25 measured by the measuring unit 31 is lower than the reference value, it is determined to be abnormal.

作為其他例,運轉控制部30,在診斷運轉中使用煞車裝置17使車廂10進行確定的動作。例如,運轉控制部30,使車廂10往上述確定的方向以確定的速度移動。運轉控制部30,當車廂10以上述確定的速度移動時,使煞車裝置17動作。煞車裝置17一動作,車廂10就開始減速,之後車廂10停止。測量部31,測量從煞車裝置17動作到車廂10停止測量車廂10移動的距離。以下,標記此距離為移動距離L1。例如,移動距離L1的測量,根據來自電動機16的旋轉軸中設置的編碼器的旋轉信號進行。調速絞纜輪22的旋轉軸中設置編碼器時,移動距離L1的測量,根據來自調速絞纜輪22的旋轉軸中設置的編碼器的旋轉信號進行也可以。以測量部31測量的移動距離L1超過基準值時,判定異常。 As another example, the operation control unit 30 uses the braking device 17 to make the vehicle 10 perform a certain operation during the diagnostic operation. For example, the operation control unit 30 moves the vehicle 10 at a predetermined speed in the predetermined direction as described above. The operation control unit 30 operates the braking device 17 when the vehicle body 10 is moving at the speed determined as described above. When the braking device 17 is actuated, the vehicle 10 starts to decelerate, and then the vehicle 10 stops. The measuring unit 31 measures the distance from when the braking device 17 is actuated until the vehicle 10 stops moving. Hereinafter, this distance is denoted as the moving distance L1. For example, the measurement of the moving distance L1 is performed based on a rotation signal from an encoder provided in the rotation shaft of the motor 16 . When an encoder is provided on the rotating shaft of the speed control reel 22 , the measurement of the moving distance L1 may be performed based on the rotation signal from the encoder provided on the rotating shaft of the speed control winch 22 . When the moving distance L1 measured by the measuring unit 31 exceeds the reference value, it is determined to be abnormal.

For example, the operation control unit 30 causes the car 10 to proceed to the terminal floor at a determined speed faster than the second reference speed. Thereby, the safety device 24 operates. The measurement unit 31 measures the distance from the actuation of the safety device 24 to the time when the vehicle 10 stops the movement of the vehicle 10 . Hereinafter, this distance is denoted as the moving distance L2. For example, the measurement of the moving distance L2 is performed based on a rotation signal from an encoder provided in the rotation shaft of the motor 16 . When an encoder is provided on the rotating shaft of the speed control winch 22 , the measurement of the moving distance L2 may be performed based on the rotation signal from the encoder provided on the rotating shaft of the speed control winch 22 . When the moving distance L2 measured by the measuring unit 31 exceeds the reference value, it is determined to be abnormal.

The measurement values transmitted to the data center 2 include, for example, the minimum voltage value Vmin, the moving distance L1, and the moving distance L2. In addition, the function for determining the presence or absence of abnormality may be provided by the elevator 1 or provided by the data center 2 . When the elevator 1 is provided with the above-described determination function, the determination of the presence or absence of abnormality is performed, for example, after the completion of the diagnostic operation. When the data center 2 is equipped with the above-mentioned judgment function, whether there is an abnormality judgment, for example It is performed after the process of S105.

The maintenance terminal 40 includes a thermometer 41 and a communication unit 42 . The communication unit 42 communicates with the control device 18 . For example, when the maintenance terminal 40 is connected to the control device 18, Yes is determined in S201. The communication unit 42 may communicate with the control device 18 via the communication device 26 . The communication unit 42 may communicate with the control device 18 via a device installed in the car 10 . The communication unit 42 may communicate wirelessly with the control device 18 .

S201中判定為Yes時,根據控制裝置18,判定維護終端40是否存在於升降梯間12內(S202)。例如,設置控制裝置18在升降梯間12中,有線連接維護終端40至控制裝置18時,S202中判定為Yes。保養員,攜帶維護終端40時,例如操作升降梯間12中配置的確定開關時,S202中判定為Yes。作為其他例,操作車廂10上設置的維持開關時,S202中判定為Yes。 When it is judged as Yes in S201, it is judged by the control apparatus 18 whether the maintenance terminal 40 exists in the elevator hall 12 (S202). For example, when the control device 18 is installed in the elevator hall 12 and the maintenance terminal 40 is wired to the control device 18, it is determined as Yes in S202. When the maintenance worker carries the maintenance terminal 40, for example, when operating the confirmation switch arranged in the elevator hall 12, the determination is Yes in S202. As another example, when the maintenance switch provided in the vehicle compartment 10 is operated, it is determined as Yes in S202.

The value acquired in S203 is the actual measurement value of the temperature of the elevator room 12 . The temperature measurement value acquired by the temperature acquisition unit 32 is transmitted to the data center 2 (S204).

如第1圖所示,資料中心2,例如包括記憶部50(記憶手段)、變動算出部51(算出手段)、推移確定部52(第1確定手段、確定手段)以及通訊部53。以下,也參照第6到9圖,說明關於資料中心2具備的機能。第6圖係顯示資料中心2的動作例流程圖。 As shown in FIG. 1 , the data center 2 includes, for example, a storage unit 50 (memory means), a variation calculation unit 51 (calculation means), a transition determination unit 52 (first determination means, determination means), and a communication unit 53 . Hereinafter, the functions of the data center 2 will be described with reference to FIGS. 6 to 9 as well. FIG. 6 is a flowchart showing an example of the operation of the data center 2 .

判定資料中心2是否從升降梯1接收到測量部31測量的值 (S301)。S105中,從升降梯1傳送的測量值,由通訊部53接收。通訊部53,從升降梯1一接收測量值,就記憶接收的測量值在記憶部50內(S302)。藉此,記憶部50內,在診斷運轉中記憶測量部31測量的值。即,記憶部50內,記憶關於車廂10動作的值以及關於確定機器的值。 It is determined whether the data center 2 has received the value measured by the measuring unit 31 from the elevator 1 (S301). In S105 , the measurement value transmitted from the elevator 1 is received by the communication unit 53 . When the communication unit 53 receives the measurement value from the elevator 1, it stores the received measurement value in the memory unit 50 (S302). Thereby, in the memory part 50, the value measured by the measurement part 31 is memorize|stored during the diagnostic operation. That is, in the memory unit 50, the values related to the operation of the car 10 and the values related to the specific device are stored.

診斷運轉,例如定期進行。記憶部50內,定期記憶診斷運轉測量的電池25的最小電壓值Vmin。作為其他例,記憶部50內,定期記憶診斷運轉測量的車廂10的移動距離L1。作為其他例,記憶部50內,定期記憶診斷運轉測量的車廂10的移動距離L2。 Diagnosis runs, for example, periodically. In the memory unit 50, the minimum voltage value Vmin of the battery 25 measured during the diagnostic operation is periodically stored. As another example, in the memory unit 50, the travel distance L1 of the vehicle 10 measured by the diagnostic operation is periodically stored. As another example, in the memory unit 50, the travel distance L2 of the vehicle 10 measured by the diagnostic operation is periodically stored.

又,根據資料中心2,判定是否從升降梯1接收溫度取得部32取得的溫度實測值(S303)。S204中,從升降梯1傳送的溫度實測值,由通訊部53接收。通訊部53,從升降梯1一接收溫度實測值,就記憶接收的實測值至記憶部50內(S304)。藉此,記憶部50內,記憶溫度計41測量的升降梯間12的溫度實測值。保養員,例如進行定期的維持操作。記憶部50內,定期記憶溫度計41測量的升降梯間12的溫度實測值。 Moreover, according to the data center 2, it is judged whether the temperature measurement value acquired by the temperature acquisition part 32 is received from the elevator 1 (S303). In S204 , the actual temperature measurement value transmitted from the elevator 1 is received by the communication unit 53 . The communication unit 53, upon receiving the actual temperature measurement value from the elevator 1, stores the received actual measurement value in the memory unit 50 (S304). Thereby, in the memory|storage part 50, the actual measurement value of the temperature of the elevator room 12 measured by the thermometer 41 is memorize|stored. Maintenance staff, for example, to perform regular maintenance operations. In the storage part 50, the actual temperature measurement value of the elevator room 12 measured by the thermometer 41 is memorize|stored regularly.

第7圖,係顯示資料中心2的其他動作例流程圖。例如,記憶部50內,記憶診斷運轉中測量的電池25的最小電壓值Vmin。變動算出部51,從記憶部50讀出電池25的最小電壓值Vmin(S401)。 FIG. 7 is a flowchart showing another example of the operation of the data center 2 . For example, in the memory unit 50, the minimum voltage value Vmin of the battery 25 measured during the diagnostic operation is stored. The fluctuation calculation unit 51 reads the minimum voltage value Vmin of the battery 25 from the memory unit 50 (S401).

第8圖係顯示電池25的最小電壓值Vmin的經過時間變化圖。第8圖所示的曲線A,顯示某曲線A的診斷運轉中測量的最小電壓值Vmin的經過時間變化。曲線B,顯示其他升降梯B的診斷運轉中測量的最小電壓值Vmin的經過時間變化。 FIG. 8 is a graph showing the elapsed time change of the minimum voltage value Vmin of the battery 25 . The curve A shown in FIG. 8 shows the elapsed time change of the minimum voltage value Vmin measured during the diagnostic operation of a certain curve A. As shown in FIG. The curve B shows the elapsed time change of the minimum voltage value Vmin measured during the diagnostic operation of the other elevator B. As shown in FIG.

如第8圖所示,最小電壓值Vmin的經過時間變化中,包含長期變動成分與季節變動成分。長期變動成分,主要起因於電池25惡化而產生。例如,由於電池25惡化,最小電壓值Vmin隨著時間經過慢慢成為小的值。另一方面, 季節變動成分,主要起因於設置電池25的升降梯間12的溫度變化而產生。例如,最小電壓值Vmin,在升降梯間12的溫度變高的夏天,成為大的值,在升降梯間12的溫度變低的冬天,成為小的值。 As shown in FIG. 8, the elapsed time change of the minimum voltage value Vmin includes a long-term fluctuation component and a seasonal fluctuation component. The long-term fluctuation component is mainly caused by the deterioration of the battery 25 . For example, due to deterioration of the battery 25, the minimum voltage value Vmin gradually becomes a small value with the passage of time. on the other hand, The seasonal variation component is mainly caused by the temperature change of the elevator room 12 in which the battery 25 is installed. For example, the minimum voltage value Vmin has a large value in summer when the temperature of the elevator car 12 is high, and has a small value in winter when the temperature of the elevator car 12 is low.

變動算出部51,根據從最小電壓值Vmin的經過時間變化除去長期變動成分,算出經過時間變化的季節變動成分(S402)。例如,變動算出部51,計算某月測量的最小電壓值與次年相同月份測量的最小電壓值之間的差異,作為長期變動成分。變動算出部51,計算平均複數月份的上述差異的值作為長期變動成分也可以。變動算出部51,計算某年測量的最小電壓值的最大值與次年測量的最小電壓值的最大值之間的差異作為長期變動成分也可以。變動算出部51,某年測量的最小電壓值的最小值與次年測量的最小電壓值的最小值之間的差異作為長期變動成分也可以。又,變動算出部51,根據以統計法確定具有長期變動成分與周期變動成分之預測模型相同,求出長期變動成分也可以。作為上述預測模型,例如,可以採用表現為以1次函數或2次函數表現的成分與以三角函數表現的成分的合計的模型。作為上述預測模型,採用其他的模型也可以。 The fluctuation calculation unit 51 calculates the seasonal fluctuation component of the elapsed time change by removing the long-term fluctuation component from the elapsed time change of the minimum voltage value Vmin ( S402 ). For example, the fluctuation calculation unit 51 calculates the difference between the minimum voltage value measured in a certain month and the minimum voltage value measured in the same month in the following year as a long-term fluctuation component. The fluctuation calculation unit 51 may calculate the value of the above-mentioned difference of the average plural months as the long-term fluctuation component. The fluctuation calculation unit 51 may calculate the difference between the maximum value of the minimum voltage value measured in a certain year and the maximum value of the minimum voltage value measured in the next year as a long-term fluctuation component. The fluctuation calculation unit 51 may use the difference between the minimum value of the minimum voltage value measured in a certain year and the minimum value of the minimum voltage value measured in the next year as a long-term fluctuation component. In addition, the fluctuation calculation unit 51 may calculate the long-term fluctuation component based on the same prediction model as having the long-term fluctuation component and the cyclic fluctuation component determined by the statistical method. As the above-mentioned prediction model, for example, a model that expresses a sum of components expressed by a linear function or a quadratic function and a component expressed by a trigonometric function can be used. As the above-mentioned prediction model, other models may be used.

變動算出部51,在S402中算出季節變動成分的周期與振幅也可以。算出的季節變動成分的振幅,對應升降梯間12的夏天溫度與冬天溫度之間的差。 The fluctuation calculation unit 51 may calculate the period and amplitude of the seasonal fluctuation component in S402. The calculated amplitude of the seasonal variation component corresponds to the difference between the summer temperature and the winter temperature of the elevator car 12 .

其次,推移確定部52,從記憶部50讀出升降梯間12的溫度實測值(S403)。推移確定部52,根據S402中算出的最小電壓值Vmin的經過時間變化的季節變動成分與S403讀出的溫度實測值,確定升降梯間12的溫度推移(S404)。 Next, the determination part 52 is moved, and the temperature measurement value of the elevator room 12 is read out from the memory part 50 (S403). The transition determination unit 52 determines the temperature transition of the elevator hall 12 based on the seasonal variation component of the elapsed time change of the minimum voltage value Vmin calculated in S402 and the measured temperature value read out in S403 (S404).

第9圖,係用以說明推移確定部52的機能圖。例如,記憶部50中,預先記憶用以轉換最小電壓值Vmin的經過時間變化的季節變動成分成為相對溫度推移的第1轉換表。推移確定部52,利用第1轉換表,轉換S402中算出的季節變動成分成為相對溫度推移。又,推移確定部52,根據S403中讀出的溫度實測 值,決定相對溫度推移的偏移值。藉此,推移確定部52,確定升降梯間12的絕對溫度推移。以下,只稱絕對溫度推移為「溫度推移」。 FIG. 9 is a functional diagram for explaining the shift determination unit 52 . For example, the storage unit 50 stores in advance a first conversion table for converting the seasonal variation component of the temporal change of the minimum voltage value Vmin into the relative temperature transition. The transition determination unit 52 converts the seasonal variation component calculated in S402 into a relative temperature transition using the first conversion table. In addition, the transition determination unit 52 measures the actual temperature based on the temperature read in S403. value to determine the offset value relative to the temperature transition. Thereby, the transition determination part 52 determines the absolute temperature transition of the elevator room 12 . Hereinafter, the absolute temperature transition is simply referred to as "temperature transition".

第9圖中,推移確定部52確定的升降梯間12的溫度推移以曲線C表示。可以確定曲線C的話,可以推定過去及未來的確定日的升降梯間12溫度推移。又,保養員訪問時,實測溫度與上述推定的溫度不一致時,根據機率模型求出實際溫度也可以。 In FIG. 9, the temperature transition of the elevator room 12 determined by the transition determination unit 52 is represented by a curve C. As shown in FIG. If the curve C can be identified, it is possible to estimate the temperature transition of the elevator hall 12 on the past and future fixed days. In addition, when the actual temperature does not agree with the above-mentioned estimated temperature at the time of the visit by the maintenance staff, the actual temperature may be obtained from the probability model.

本實施形態所示的實例中,利用電池25的最小電壓值Vmin,確定升降梯間12的溫度推移。電池25的最小電壓值Vmin,係診斷運轉中測量的值。因此,如果是本實施形態所示的實例,不必常設新的測量器,可以確定升降梯間12的溫度推移。維持檢查中,保養員的維持項目也沒增加。 In the example shown in this embodiment, the minimum voltage value Vmin of the battery 25 is used to determine the temperature transition of the elevator car 12 . The minimum voltage value Vmin of the battery 25 is a value measured during the diagnostic operation. Therefore, in the example shown in this embodiment, it is not necessary to permanently install a new measuring device, and the temperature transition of the elevator room 12 can be determined. During the maintenance inspection, the maintenance items of the maintenance staff did not increase.

本實施形態中,為了確定升降梯間12的溫度推移,說明關於利用電池25的最小電壓值Vmin的實例。這是一例。根據與上述確定方法相同的方法,利用車廂10的移動距離L1確定升降梯間12的溫度推移也可以。利用車廂10的移動距離L2確定升降梯間12的溫度推移也可以。又,電池25,不是通常運轉使用的機器。因此,利用電池25的最小電壓值Vmin時,具有不受車廂10的行駛次數等的影響而可以確定升降梯間12的溫度推移的優點。 In the present embodiment, in order to determine the temperature transition of the elevator room 12, an example of using the minimum voltage value Vmin of the battery 25 will be described. This is an example. According to the same method as the above-mentioned determination method, the temperature transition of the elevator room 12 may be determined using the moving distance L1 of the vehicle compartment 10 . The temperature transition of the elevator room 12 may be determined by the moving distance L2 of the car 10 . In addition, the battery 25 is not a device normally used for operation. Therefore, when the minimum voltage value Vmin of the battery 25 is used, there is an advantage that the temperature transition of the elevator car 12 can be determined without being influenced by the number of times of travel of the car 10 or the like.

本實施形態中,利用升降梯間12的溫度實測值,說明關於確定升降梯間12的溫度推移的實例。升降梯間12,係設置機器的升降梯空間的一例。升降梯1備置機械室時,升降梯空間是機械室也可以。即,推移確定部52,利用溫度計41測量的機械室的溫度實測值,確定機械室的溫度推移也可以。在此情況下,S202中,判定維護終端40是否存在機械室內。S202中判定為Yes時,溫度取得部32取得溫度計41測量的溫度實測值。 In the present embodiment, an example of specifying the temperature transition of the elevator hall 12 will be described using the actual measurement value of the temperature of the elevator hall 12 . The elevator room 12 is an example of an elevator space in which equipment is installed. When the elevator 1 is equipped with a machine room, the elevator space may be a machine room. That is, the transition specifying unit 52 may specify the temperature transition of the machine room using the actual measurement value of the temperature of the machine room measured by the thermometer 41 . In this case, in S202, it is determined whether or not the maintenance terminal 40 exists in the machine room. When it is determined as Yes in S202, the temperature acquisition unit 32 acquires the actual temperature value measured by the thermometer 41.

又,升降梯間12的溫度與機械室的溫度之間的差,很多比較小。因此,推移確定部52,利用溫度計41測量的升降梯間12的溫度實測值,確定機 械室的溫度推移也可以。推移確定部52,根據溫度計41測量的機械室的溫度實測值,確定升降梯間12的溫度推移也可以。即,推移確定部52,利用溫度計41測量的升降梯空間的溫度實測值,確定升降梯空間的溫度推移。 In addition, the difference between the temperature of the elevator room 12 and the temperature of the machine room is often relatively small. Therefore, the determination unit 52 is moved, and the actual temperature measurement value of the elevator room 12 measured by the thermometer 41 is used to determine the machine. The temperature of the mechanical room can also be shifted. The transition specifying unit 52 may specify the temperature transition of the elevator room 12 based on the actual temperature measurement value of the machine room measured by the thermometer 41 . That is, the transition determination part 52 determines the temperature transition of the elevator space using the actual measurement value of the temperature of the elevator space measured by the thermometer 41 .

其次,利用資料中心2中備置的溫度推移確定裝置,說明關於建構維持計畫系統的實例。第10圖係顯示資料中心2的其他實例圖。第10圖所示的資料中心2,除了記憶部50、變動算出部51、推移確定部52以及通訊部53,更包括壽命算出部54(第2算出手段)以及判定部55(判定手段)。第11圖,係顯示資料中心2的其他動作例圖。第11圖所示的動作,例如在第7圖所示的動作後進行。 Next, an example of constructing a maintenance planning system will be described using the temperature transition determination device provided in the data center 2 . FIG. 10 is another example diagram showing the data center 2 . The data center 2 shown in FIG. 10 includes a life calculation unit 54 (second calculation means) and a judgment unit 55 (judgment means) in addition to a memory unit 50, a fluctuation calculation unit 51, a transition determination unit 52, and a communication unit 53. FIG. 11 is a diagram showing another example of the operation of the data center 2 . The operation shown in FIG. 11 is performed after the operation shown in FIG. 7 , for example.

S404中確定升降梯空間的溫度推移時,壽命算出部54算出此升降梯空間中配置的元件壽命(S501)。例如,壽命算出部54,根據推移確定部52確定的溫度推移與車廂10的行駛履歷進行元件惡化的模擬,算出此元件的壽命。車廂10的行駛履歷,也可以是車廂10的行駛次數,也可以是車廂10的行駛距離。例如,壽命算出部54,算出配置在控制裝置18內部的電氣元件壽命。壽命算出部54,算出傳動帶等的樹脂元件的壽命也可以。 When the temperature transition of the elevator space is determined in S404, the lifetime calculation unit 54 calculates the lifetime of the components arranged in the elevator space (S501). For example, the life calculation unit 54 calculates the life of the element by simulating the deterioration of the element based on the temperature transition specified by the transition specifying unit 52 and the travel history of the vehicle cabin 10 . The travel history of the car 10 may be the number of travel times of the car 10 or the travel distance of the car 10 . For example, the life calculation unit 54 calculates the life of the electrical components arranged inside the control device 18 . The life calculation unit 54 may calculate the life of a resin element such as a transmission belt.

判定部55,判定元件的檢查時期(S502)。判定部55,根據壽命算出部54算出的元件壽命,進行檢查時期的判定。判定部55,在S502中判定元件的交換時期也可以。藉此,可以制作根據元件的檢查時期或交換時期的適當維持計畫。 The determination unit 55 determines the inspection time of the component (S502). The determination unit 55 determines the inspection timing based on the element life calculated by the life calculation unit 54 . The determination unit 55 may determine the replacement timing of the components in S502. Thereby, an appropriate maintenance plan can be prepared according to the inspection timing or replacement timing of the components.

第12圖,係顯示資料中心2的其他實例圖。第12圖所示的資料中心2,除了記憶部50、變動算出部51、推移確定部52以及通訊部53,例如更包括類別決定部56以及判定部55。第13圖係顯示資料中心2的其他動作例圖。第13圖所示的動作,例如在第7圖所示的動作後進行。 FIG. 12 shows another example of the data center 2 . The data center 2 shown in FIG. 12 includes, for example, a category determination unit 56 and a determination unit 55 in addition to a storage unit 50 , a variation calculation unit 51 , a transition determination unit 52 , and a communication unit 53 . FIG. 13 is a diagram showing another example of the operation of the data center 2 . The operation shown in FIG. 13 is performed, for example, after the operation shown in FIG. 7 .

S404中確定升降梯空間的溫度推移時,類別決定部56,決定此升降梯空間所屬的環境類別(S601)。例如,根據設置升降梯1的建築物構造,其升 降梯空間的環境不同。又,根據設置升降梯1的位置及方向,其升降梯空間的環境不同。例如,設置升降梯1在大規模建築物的中央部時,其升降梯空間的溫度一整年固定。又,在外氣容易進入的位置設置升降梯1時,其升降梯空間的溫度容易受外氣溫度影響。升降梯1是所謂透明升降梯且設置在接受直射日光的位置時,其升降梯空間的溫度,改變比外氣溫度變化大。 When the temperature transition of the elevator space is determined in S404, the category determination unit 56 determines the environmental category to which the elevator space belongs (S601). For example, depending on the structure of the building in which the elevator 1 is installed, the The environment of the escalator space is different. In addition, the environment of the elevator space varies depending on the position and direction in which the elevator 1 is installed. For example, when the elevator 1 is installed in the center of a large-scale building, the temperature of the elevator space is constant throughout the year. Furthermore, when the elevator 1 is installed at a position where the outside air can easily enter, the temperature of the elevator space is easily affected by the outside air temperature. When the elevator 1 is a so-called transparent elevator and is installed in a position receiving direct sunlight, the temperature of the elevator space changes more than the outside air temperature.

第12及13圖所示的實例中,預先設定複數的環境類別。又,預先設定用以決定升降梯空間所屬的環境類別之第1分類條件。類別決定部56,根據推移確定部52確定的溫度推移與第1分類條件,進行環境類別的決定。例如,類別決定部56,根據確定的溫度推移,算出最高溫度、最低溫度、推移周期以及推移幅度等的特徵量。類別決定部56,應用算出的特徵量至第1分類條件,決定環境類別。 In the examples shown in Figs. 12 and 13, a plurality of environment types are set in advance. Moreover, the 1st classification condition for determining the environmental type to which the elevator space belongs is set in advance. The category determination unit 56 determines the environmental category based on the temperature transition determined by the transition determination unit 52 and the first classification condition. For example, the type determination unit 56 calculates characteristic quantities such as the highest temperature, the lowest temperature, the transition period, and the transition width, based on the specified temperature transition. The category determination unit 56 determines the environmental category by applying the calculated feature amount to the first classification condition.

判定部55,判定元件的檢查時期(S602)。判定部55,根據類別決定部56決定的升降梯空間的環境類別,判定配置在其升降梯空間的元件的檢查時期。例如,每一環境類別預先設定元件的檢查周期。判定部55,在S602中判定元件的交換時期也可以。藉此,可以制作對應元件的檢查時期或交換時期的適當維持計畫。 The determination unit 55 determines the inspection time of the component (S602).

第14圖係顯示資料中心2的其他實例圖。第14圖所示的資料中心2,除了記憶部50、變動算出部51、推移確定部52以及通訊部53,例如更包括類別決定部56、推移確定部57(第2確定手段)、壽命算出部54(第2算出手段)以及判定部55(判定手段)。第15圖,係顯示資料中心2的其他動作例圖。第15圖所示的動作,例如在第7圖所示的動作之後進行。 FIG. 14 is another example diagram showing the data center 2 . The data center 2 shown in FIG. 14 includes, for example, a type determination unit 56 , a transition determination unit 57 (second determination means), a life calculation unit, in addition to a memory unit 50 , a fluctuation calculation unit 51 , a transition determination unit 52 , and a communication unit 53 . part 54 (second calculation means) and determination part 55 (determination means). FIG. 15 is a diagram showing another example of the operation of the data center 2 . The operation shown in FIG. 15 is performed after the operation shown in FIG. 7 , for example.

步驟S404中,確定升降梯空間的溫度推移時,類別決定部56,決定其升降梯空間所屬的環境類別(S701)。如第14及15圖所示的實例,類別決定部56,根據推移確定部52確定的溫度推移與外氣溫度的差,進行環境類別的決定。 外氣溫度,例如可以從氣象局等的外部機關取得。類別決定部56,根據依溫度推移推定的某日的升降梯空間的溫度與那天的外氣溫度之間的差,決定環境類別。 In step S404, when the temperature transition of the elevator space is determined, the category determination unit 56 determines the environmental category to which the elevator space belongs (S701). As in the example shown in FIGS. 14 and 15, the type determination unit 56 determines the environment type based on the difference between the temperature transition determined by the transition determination unit 52 and the outside air temperature. The outside air temperature can be obtained, for example, from an external organization such as the Meteorological Bureau. The type determination unit 56 determines the environmental type based on the difference between the temperature of the elevator space on a certain day estimated from the temperature transition and the outside air temperature on that day.

例如,在升降梯空間設置空調裝置時,上述差依季節變動。在外氣容易進內的位置設置升降梯1時,上述差一整年間變得比較小。也根據形成升降梯間12的牆壁材質,上述差變動。 For example, when an air conditioner is installed in an elevator space, the above-mentioned difference varies seasonally. When the elevator 1 is installed at a position where the outside air can easily enter, the above-mentioned difference becomes relatively small throughout the year. The difference described above also varies depending on the material of the walls forming the elevator room 12 .

第14及15圖所示的實例中,預先設定複數的環境類別。又,預先設定用以決定升降梯空間所屬的環境類別之第2類條件。類別決定部56,例如,根據上述差與第2分類條件,進行環境類別的決定。 In the examples shown in Figs. 14 and 15, a plurality of environment types are set in advance. In addition, the second type of condition for determining the environmental type to which the elevator space belongs is set in advance. The type determination unit 56 determines the environmental type based on the difference and the second classification condition, for example.

又,第14及15圖所示的實例中,記憶部50內,預先記憶環境類別另外的第2轉換表。第2轉換表,係用以轉換外氣溼度為升降梯空間溼度的表。例如,為了制作第2轉換表,實際測量各種升降梯空間溼度。第2轉換表,係利用外氣溼度與升降梯空間溼度實測值事前制作,記憶在記憶部50內。外氣溼度,例如可以從氣象局等的外部機關取得。 In addition, in the example shown in FIGS. 14 and 15, in the storage unit 50, a second conversion table for another environment type is stored in advance. The second conversion table is a table for converting the outside air humidity into the elevator space humidity. For example, in order to create the second conversion table, various elevator space humidity is actually measured. The second conversion table is prepared in advance using the measured values of the outside air humidity and the elevator space humidity, and is stored in the memory unit 50 . The outside air humidity can be obtained, for example, from an external organization such as the Meteorological Bureau.

推移確定部57,根據類別決定部56決定的環境類別,確定升降梯空間的溼度推移。第16圖係用以說明推移確定部57的機能圖。第16圖,利用建築物中備置空調設備但升降梯間12內不備置空調設備的環境類別的第2轉換表,顯示確定溼度推移例。例如,推移確定部57,從記憶部50讀出對應的第2轉換表(S702)。即,推移確定部57,在S702中,從記憶部50讀出對應類別決定部56決定的環境類別之第2轉換表。推移確定部57,利用讀出的第2轉換表,確定升降梯空間的溼度推移(S703)。 The transition determination unit 57 determines the humidity transition in the elevator space based on the environmental type determined by the type determination unit 56 . FIG. 16 is a functional diagram for explaining the shift determination unit 57 . Fig. 16 shows an example of a certain humidity transition using the second conversion table of the environment type in which the air conditioner is installed in the building but the air conditioner is not installed in the elevator hall 12. For example, the shift determination unit 57 reads out the corresponding second conversion table from the storage unit 50 (S702). That is, in S702 , the transition determination unit 57 reads out the second conversion table corresponding to the environmental type determined by the type determination unit 56 from the storage unit 50 . The transition specifying unit 57 specifies the humidity transition in the elevator space using the read out second conversion table (S703).

S703中確定升降梯空間的溼度推移時,壽命算出部54,算出其升降梯空間內配置的元件壽命(S704)。例如,壽命算出部54,根據推移確定部52確定的溫度推移、推移確定部57確定的溼度推移以及車廂10的行駛履歷,進行 元件惡化的模擬,算出此元件的壽命。車廂10的行駛履歷,可以是車廂10的行駛次數,也可以是車廂10的行駛距離。 When it is determined in S703 that the humidity in the elevator space has changed, the life calculation unit 54 calculates the life of the components arranged in the elevator space (S704). For example, the life calculation unit 54 performs the calculation based on the temperature transition determined by the transition determination unit 52 , the humidity transition determined by the transition determination unit 57 , and the travel history of the vehicle compartment 10 . Simulation of component deterioration, calculate the life of this component. The travel history of the car 10 may be the number of travels of the car 10 or the travel distance of the car 10 .

判定部55,判定元件的檢查時期(S705)。判定部55,根據壽命算出部54算出的元件壽命,進行檢查時期的判定。判定部55,在S705中判定元件的交換時期也可以。藉此,可以制作根據元件的檢查時期或交換時期的適當維持計畫。 The determination unit 55 determines the inspection time of the component (S705). The determination unit 55 determines the inspection timing based on the element life calculated by the life calculation unit 54 . The determination unit 55 may determine the replacement timing of the components in S705. Thereby, an appropriate maintenance plan can be prepared according to the inspection timing or replacement timing of the components.
