  However, in an elevator such as an elevator, a maintenance company may be changed according to the intention of an administrator. In this case, the maintenance company after the change does not grasp the replacement history of the part in a certain period from the start of the elevator operation. For this reason, when a basic replacement period calculation device is used, the replacement period of parts can be calculated erroneously.

  The present invention has been made to solve the above-described problems. The object of the present invention is to appropriately calculate the replacement cycle of the part even if the part replacement history from the start of the elevator operation to the replacement cycle calculation time of the part is not grasped.

Embodiment 1 FIG.
FIG. 1 is a block diagram of a part replacement period calculation device for an elevator according to Embodiment 1 of the present invention.

  In FIG. 1, the 1st memory | storage device 1 memorize | stores the contract log | history in each of several elevator. For example, the first storage device 1 stores a contract history in each of a plurality of elevators. For example, the 1st memory | storage device 1 memorize | stores the contract log | history in each of several passenger conveyors.

  The 2nd memory | storage device 2 memorize | stores the replacement | exchange history of the components utilized for each of several elevators. For example, the second storage device 2 stores a replacement history of parts used for each of the plurality of elevators. For example, the 2nd memory | storage device 2 memorize | stores the replacement | exchange log | history of the components currently utilized for each of several passenger conveyors.

  For example, the display device 3 includes a liquid crystal monitor. The display device 3 is provided so as to project an image according to a command from the outside.

  The replacement cycle calculation device 4 includes a contract transition extraction unit 4a, a replacement history extraction unit 4b, a replacement cycle calculation unit 4c, and a display control unit 4d.

  The contract transition extraction unit 4 a is connected to the first storage device 1. The contract transition extraction unit 4a extracts the transition of each contract of the elevator in which the part for which the replacement period is calculated is extracted from the contract history of the first storage device 1. For example, the contract transition extraction unit 4a extracts the transition of each contract of the model X when the part Y of the model X of the elevator is designated.

  The replacement history extraction unit 4 b is connected to the second storage device 2. The replacement history extraction unit 4b extracts, from each replacement history in the second storage device 2, the replacement timing of the relevant part during the maintenance contract period for each of the elevators whose contract transitions have been extracted by the contract transition extraction unit 4a. .

  The replacement cycle calculation unit 4c calculates the replacement cycle of the part based on the distribution of replacement times of the part extracted by the replacement history extraction unit 4b for each of the elevators. At this time, the replacement cycle calculation unit 4c calculates the replacement cycle of the part excluding the non-contracted period for each of the elevators whose contract transitions are extracted by the contract transition extraction unit 4a. The replacement period calculation unit 4c calculates a total replacement period of the part by using a statistical method for the replacement period of the part in each of the elevators.

  The display control unit 4 d is connected to the display device 3. The display control unit 4d causes the display device 3 to display the calculation result by the replacement period calculation unit 4c. For example, the display control unit 4d causes the display device 3 to display the replacement period of the part in each elevator in association with the symbol of the elevator. For example, the display control unit 4d causes the display device 3 to display the total replacement period of the component in association with the symbol of the component.

Next, the classification of contract transitions by the contract transition extraction unit 4a will be described with reference to FIG.
FIG. 2 is a diagram for explaining the classification of contract transitions by the elevator part replacement period calculation apparatus according to Embodiment 1 of the present invention.

  The contract transition extraction unit 4a classifies contract transitions from the start of elevator operation to the time for calculating the replacement period of parts based on the presence or absence of the elevator maintenance contract from the viewpoint of the current maintenance company a. For example, the contract transition extraction unit 4a classifies the transition of the contract from the start of the elevator operation to the part replacement cycle calculation time from the first transition to the eighth transition.

  For example, in the first transition, the maintenance contract period is from 1987, which is the operation start time of the elevator, to 2013, which is the component replacement cycle calculation time point.

  For example, in the second transition, the non-contracted period is from 1987, which is the operation start time of the elevator, to 2013, which is the component replacement cycle calculation time point. The non-contract period is a period in which the maintenance company a does not have a maintenance contract. For example, the period in which the maintenance company b has a maintenance contract is also a non-contracted period for the maintenance company a.

  For example, in the third transition, the non-contracted period is from 1987 to 1998, which is the operation start time of the elevator. The maintenance contract period A is from 1998 to 2013, which is the time point for calculating the replacement period of parts.

  For example, in the fourth transition, the period from 1987 to 1998, which is the starting point of the elevator operation, is the non-contract period. The period from 1998 to 2005 is the maintenance contract period B. The non-contract period is from 2005 to 2013, which is the time point for calculating the replacement period of parts.

  For example, in the fifth transition, the certain period of time when the elevator starts operation is an uncontracted period. The period at the time of calculating the part replacement cycle is an uncontracted period. During these non-contract periods, the maintenance contract period and the non-contract period are repeated. In FIG. 2, the period from 1987 to 1996, which is the time when the elevator is started, is the non-contract period. The period from 1996 to 1998 is the maintenance contract period C. The period from 1998 to 2002 is the unsigned period. The maintenance contract period D is from 2002 to 2005. The non-contract period is from 2005 to 2013, which is the time point for calculating the replacement period of parts.

  For example, in the sixth transition, the maintenance contract period E is from 1987 to 1998, which is the operation start time of the elevator. The non-contracted period is from 1998 to 2013, which is the time point for calculating the replacement period of parts.

  For example, in the seventh transition, the maintenance contract period F is from 1987 to 1998, which is the operation start time of the elevator. The period from 1998 to 2005 is the unsigned period. The maintenance contract period G is from 2005 to 2013, which is the time point for calculating the replacement period of parts.

  For example, in the eighth transition, the certain period of time when the elevator starts operation is a maintenance contract period. The period when the part replacement cycle is calculated is a maintenance contract period. During these maintenance contract periods, the non-contract period and the maintenance contract period are repeated. In FIG. 2, the maintenance contract period H is from 1987 to 1996 when the elevator starts operation. The period from 1996 to 1998 is an unsigned period. The period from 1998 to 2002 is the maintenance contract period I. The period from 2002 to 2005 is the unsigned period. The maintenance contract period J is from 2005 to 2013, which is the time point for calculating the part replacement cycle.

Next, the part replacement cycle calculated without excluding the non-contracted period will be described with reference to FIG.
FIG. 3 is a diagram for explaining a component replacement cycle obtained without using the elevator component replacement cycle calculation apparatus according to Embodiment 1 of the present invention.

  FIG. 3 shows an example in which the part replacement period is erroneously calculated in the seventh transition of FIG.

  For example, in the first error pattern, the part is not replaced in the maintenance contract period F. The parts have been replaced by the maintenance company b during the non-contract period. The part has not been replaced in the maintenance contract period G. In this case, the second storage device 2 does not store the replacement history of the non-contract period. As a result, the replacement period of the part is erroneously calculated as a period from 1987 to 2013.

  For example, in the second error pattern, the part is not replaced in the maintenance contract period F. The parts have been replaced by the maintenance company b during the non-contract period. Parts have been replaced in the maintenance contract period G, 2006. In this case, the second storage device 2 does not store the replacement history of the non-contract period. As a result, the replacement period of the part is erroneously calculated as a period from 1987 to 2006.

  For example, in the third error pattern, the part is replaced in 1992 of the maintenance contract period F. The parts have been replaced by the maintenance company b during the non-contract period. Parts have been replaced in the maintenance contract period G, 2006. In this case, the second storage device 2 does not store the replacement history of the non-contract period. As a result, the replacement period of the part is erroneously calculated as a period from 1992 to 2006.

Next, with reference to FIG. 4, a method for calculating a component replacement period in the case of the third transition to the fifth transition in FIG. 2 will be described.
FIG. 4 is a diagram for explaining a method for calculating a part replacement period by the elevator part replacement period calculation apparatus according to Embodiment 1 of the present invention.

  For example, in the first pattern, the second storage device 2 stores a history that a part has been replaced only in 2006. In this case, the replacement cycle calculation unit 4c calculates a period from 2006 to 2013 as the replacement cycle of the part.

  For example, in the second pattern, the second storage device 2 stores a history that the parts have been replaced between 2006 and 2010. In this case, the replacement cycle calculation unit 4c calculates a period from 2006 to 2010 as the replacement cycle of the part.

  For example, in the third pattern, the second storage device 2 stores a history that the parts have been replaced in 2006, 2007, and 2010. In this case, the replacement cycle calculation unit 4c calculates a period from 2007 to 2010 as the replacement cycle of the part.

  For example, in the fourth pattern, the second storage device 2 does not store a history that a part has been replaced. In this case, the replacement cycle calculation unit 4c does not extract the replacement cycle of the part.

Next, with reference to FIG. 5, a method for calculating a component replacement period in the case of the sixth transition to the eighth transition in FIG. 2 will be described.
FIG. 5 is a diagram for explaining a method for calculating a part replacement period by the part replacement period calculation apparatus for an elevator according to Embodiment 1 of the present invention.

  For example, in the fifth pattern, the second storage device 2 stores a history that a part has been replaced only in 2006. In this case, the replacement cycle calculation unit 4c calculates a period from 2006 to 2013 as the replacement cycle of the part.

  For example, in the sixth pattern, the second storage device 2 stores a history that the parts have been replaced between 2006 and 2008. In this case, the replacement cycle calculation unit 4c calculates the period from 2006 to 2008 as the replacement cycle of the part.

  For example, in the seventh pattern, the second storage device 2 stores a history that the parts have been replaced in 2006, 2008, and 2010. In this case, the replacement cycle calculation unit 4c calculates a period from 2008 to 2010 as the replacement cycle of the part.

  For example, in the eighth pattern, the second storage device 2 does not store a history that a part has been replaced. In this case, the replacement cycle calculation unit 4c calculates the maintenance contract period F from 1987 to 1998 as the replacement cycle of the part.

  For example, in the ninth pattern, the second storage device 2 stores a history that the part has been replaced only in the maintenance contract period F 1992. In this case, the replacement cycle calculation unit 4c calculates a period from 1987 to 1992 as the replacement cycle of the part.

Next, the operation of the replacement period calculation device 4 in the case of the third transition to the fifth transition of the contract in FIG. 2 will be described using FIG.

  If one replacement time is not extracted in step S12, the process proceeds to step S14. In step S <b> 14, the replacement history extraction unit 4 b determines whether scanning for all maintenance contract periods has been completed.

  If scanning of the entire maintenance contract period is not completed in step S14, the process proceeds to step S15. In step S15, the replacement history extraction unit 4b scans the maintenance contract period closest to the calculation time of the part replacement period in the remaining maintenance contract period as the next maintenance contract period. Thereafter, the operations after step S12 are repeated.

  If scanning of the entire maintenance contract period is completed in step S14, the process proceeds to step S16. In step S16, the replacement cycle calculation unit 4c does not calculate the replacement cycle of the part on the assumption that the replacement history of the part is the fourth pattern. Thereafter, the operation ends.

Next, the operation of the replacement period calculation device 4 in the case of the sixth transition to the eighth transition of the contract in FIG. 2 will be described using FIG.
FIG. 7 is a flowchart for explaining the operation of the part replacement period calculating device for the elevator according to Embodiment 1 of the present invention.

In step S22, the replacement history extraction unit 4b determines whether or not three or more replacement times have been extracted for the part.

  If three or more replacement times are extracted in step S22, the process proceeds to step S23. In step S23, the replacement cycle calculation unit 4c calculates the replacement cycle of the part in the seventh pattern. Thereafter, the operation ends.

  If three or more replacement times are not extracted in step S22, the process proceeds to step S24. In step S24, the replacement history extraction unit 4b determines whether or not scanning of all maintenance contract periods has been completed.

  If scanning of the entire maintenance contract period is not completed in step S24, the process proceeds to step S25. In step S25, the replacement history extraction unit 4b scans the maintenance contract period closest to the part replacement period calculation time as the next maintenance contract period in the remaining maintenance contract period. Thereafter, the operations after step S22 are repeated.

  If scanning of the entire maintenance contract period is completed in step S24, the process proceeds to step S26. In step S26, the replacement history extraction unit 4b starts scanning from the maintenance contract period closest to the part replacement cycle calculation time point. In step S27, the replacement history extraction unit 4b determines whether two replacement times have been extracted for the part.

  If two replacement times are extracted in step S27, the process proceeds to step S28. In step S28, the replacement cycle calculation unit 4c calculates the replacement cycle of the part in the sixth pattern. Thereafter, the operation ends.

  If two replacement times are not extracted in step S27, the process proceeds to step S29. In step S29, the replacement history extraction unit 4b determines whether or not scanning of all maintenance contract periods has been completed.

  If scanning of the entire maintenance contract period is not completed in step S29, the process proceeds to step S30. In step S30, the replacement history extraction unit 4b scans the maintenance contract period closest to the part replacement period calculation time as the next maintenance contract period in the remaining maintenance contract period. Thereafter, the operations after step S27 are repeated.

  If scanning of the entire maintenance contract period is completed in step S29, the process proceeds to step S31. In step S31, the replacement history extraction unit 4b starts scanning from the maintenance contract period closest to the part replacement cycle calculation time point. In step S32, the replacement history extraction unit 4b determines whether one replacement time has been extracted for the part.

  If one replacement time is extracted in step S32, the process proceeds to step S33. In step S33, the replacement period calculation unit 4c determines whether or not the period in which one replacement time is extracted is a re-contract period. Specifically, the replacement period calculation unit 4c determines whether or not the period in which one replacement time is extracted is a maintenance contract period after the non-contract period.

  When the period in which one replacement time is extracted in step S33 is a re-contract period, the process proceeds to step S34. In step S34, the replacement cycle calculation unit 4c calculates the replacement cycle of the part in the fifth pattern. Thereafter, the operation ends.

  If the period in which one replacement time is extracted in step S33 is not a re-contract period, the process proceeds to step S35. In step S35, the replacement cycle calculation unit 4c calculates the replacement cycle of the part in the ninth pattern. Thereafter, the operation ends.

In step S37, the replacement history extraction unit 4b scans the maintenance contract period closest to the part replacement period calculation time in the remaining maintenance contract period as the next maintenance contract period. Thereafter, the operations after step S32 are repeated.

  When scanning of all maintenance contract periods is completed in step S36, in step S38, the replacement cycle calculation unit 4c calculates the replacement cycle of the part in the eighth pattern. Thereafter, the operation ends.

  According to Embodiment 1 demonstrated above, the replacement | exchange period of components is calculated excluding the non-contract period of an elevator. For this reason, even if it does not grasp a part of the replacement history of the part from the operation start time of the elevator to the replacement period calculation time of the part, the replacement period of the part can be appropriately calculated. Then, a total replacement period of the part is calculated by using a statistical method with respect to the replacement period of the part in each of the elevators calculated appropriately. In this case, parts can be exchanged at a reasonable cycle. As a result, the malfunction of the elevator due to the breakage of parts can be reduced.

  Further, the replacement time of the parts is accurately extracted by the replacement history extraction unit 4b. For this reason, the replacement period of the component can be accurately calculated.

  If three or more replacement times are extracted for the part during the maintenance contract period, the replacement period of the part is a period between the two most recent replacement times. For this reason, it is possible to calculate the replacement period of the part according to the current state of the elevator.

  If two replacement times are extracted for the part during the maintenance contract period, the replacement period of the part is a period between the two replacement times. For this reason, the replacement period of the part can be calculated based on the actual replacement time.

  In addition, when one replacement period is extracted for the part during the current maintenance contract period, the replacement period of the part is between the replacement period and the current time. For this reason, even when only one replacement time is extracted, the replacement period of the part can be calculated.

  Further, if the maintenance contract period is not extracted before the current maintenance contract period and the replacement time of the part is not extracted during the current maintenance contract period, the replacement period of the part is not calculated. For this reason, it can prevent that the calculated value of the replacement period of the said part becomes a result greatly different from an actual replacement period.

  In addition, if the maintenance contract period from the start of the elevator operation is extracted before the non-contract period and the replacement timing of the part is not extracted during the entire maintenance contract period, the replacement period of the part is Maintenance contract period from the start of operation. For this reason, even if the actual replacement time is not extracted, the replacement period of the part can be calculated.

  In addition, if one replacement period is extracted for the relevant part during the maintenance contract period from the start of elevator operation without extracting the replacement period during the current maintenance contract period, The replacement cycle is a period between the operation start time of the elevator and the one replacement time. For this reason, even when only one replacement time is extracted, the replacement period of the part can be calculated.

  In addition, you may apply the replacement period calculation apparatus 4 to apparatuses other than an elevator. Even in this case, the replacement cycle of the part is appropriately calculated even if a part of the replacement history of the part from the start of operation of the equipment other than the elevator to the time of calculating the replacement period of the part is not grasped be able to.
