Description

  Embodiments described herein relate generally to an elevator control device and an elevator control method.

  In recent years, as a result of a review of elevator seismic design and enforcement guidelines due to the damage of a huge earthquake, a stronger mechanism has been required to maintain the function of the elevator. On the other hand, in buildings where early restoration is required, early restoration of elevators with early restoration means such as automatic diagnosis operation was permitted.

  For example, when an earthquake is detected by an earthquake detector, or when an earthquake of a predetermined magnitude or larger comes, the elevator performs an earthquake control operation. After the elevator car stops at the nearest floor, it waits for several tens of minutes to wait for the aftershock to converge. Thereafter, automatic diagnosis operation is performed. If a series of diagnoses by automatic diagnosis operation is completed normally, temporary restoration of the elevator is permitted. As a result, it is possible to prevent a situation in which the elevator cannot be used until the inspection by the maintenance staff is completed.

  However, when an abnormality is detected in the automatic diagnosis operation, the elevator does not perform the temporary restoration operation, and the operation suspension state is continued. Moreover, although the elevator ascending / descending section is divided in advance and only a divided section where no abnormality is detected is allowed to be temporarily restored, a section included in the divided section where an abnormality is detected cannot be used. Therefore, there is a section where the use is not resumed even though there is no problem even if it is actually used.

JP 2009-57192 A

  According to an embodiment of the present invention, even when an abnormality is detected in an elevator in an operation diagnosis performed while the use of the elevator is stopped, control is performed so that the use of the elevator is resumed in a section where there is no problem even if the use is resumed.

  An elevator control device as one aspect of the present invention includes an operation control unit and a section determination unit. The operation control unit controls the elevator so that the first operation diagnosis is performed at a first speed slower than the rated speed of the elevator while the use of the elevator is stopped. The section determining unit uses the first normal section indicating the floor where the elevator abnormality is not detected in the first operation diagnosis to indicate the floor where the elevator car moves up and down when the use of the elevator is resumed. Determine the resume interval. Then, when the use of the elevator is resumed, the operation control unit controls the elevator so that the car moves up and down in the use resumption section.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(One embodiment of the present invention)
FIG. 1 is a diagram illustrating an example of an elevator according to an embodiment of the present invention. In the example of FIG. 1, the elevator control device 100, the car 201, the counterweight 202, the main rope 203, the hoisting machine 204, the baffle 205, the lifting cable 206, the information provider 207, and the landing 208 A door 209, a hoistway 210, a situation information provider (earthquake detector) 211, and a position information provider (position detector) 212 are shown.

  1 includes a status information acquisition unit (situation determination unit) 101, a status information acquisition unit (abnormality detection unit) 102, a position information acquisition unit 103, an operation control unit 104, and a usage range determination unit. 105 and a storage unit 106. In addition, the use range determining unit 105 includes a section determining unit 107 and a floor determining unit 108.

  In the present embodiment, the use of the elevator is stopped under a specific situation. For example, it is assumed that the use is stopped in the event of a disaster such as an earthquake or a fire. Hereinafter, a case where the use is stopped due to an earthquake will be described. However, the situation is not particularly limited.

  Moreover, in this embodiment, one or more automatic diagnostic driving | operations are performed while the utilization of an elevator is stopped. Then, based on the result of the automatic diagnosis operation, whether or not the temporary restoration operation can be executed is determined. The use of the elevator is resumed by the temporary restoration operation.

  The temporary recovery operation is an operation for achieving early recovery from the suspension of use. For this reason, the range of operation and the like may differ from normal operation, which is normal operation of the elevator before the use of the elevator is stopped. For example, in normal operation, the car 201 moves up and down from the first basement floor to the uppermost floor 8th floor, but in the temporary restoration operation, the car 201 may move up and down from the first floor to the fourth floor. Thus, the floors where the car 201 moves up and down may be different. In addition, for example, the speed at which the car 201 moves up and down, the floor at which the car 201 can stop, and the like may be different from those in normal operation. Limits in these temporary restoration operations are also determined based on the results of the automatic diagnosis operation.

  The elevator control device 100 controls components other than the elevator control device 100 such as the hoisting machine 204 to cause the elevator to perform an automatic diagnosis operation and the like. Hereinafter, components and processing of the elevator control apparatus 100 will be described. Components other than the elevator control device 100 may be the same as those of a known elevator. Therefore, detailed description of components other than the elevator control device 100 is omitted.

  The situation information acquisition unit 101 acquires information about a specific situation in which the use of the elevator is stopped from an external device. In the example of FIG. 1, information related to an earthquake is acquired from the earthquake detector 211. The information on the earthquake includes, for example, the presence / absence of an earthquake, the seismic intensity, and the like.

  The determination as to whether the situation is a specific situation may be made by the situation information acquisition unit 101 or the operation control unit 104. The component that determines whether or not a specific situation is present can be said to be a situation determination unit. Alternatively, the external device may determine that the situation is a specific situation, and the situation information acquisition unit 101 may acquire an instruction to stop using the external device.

  The state information acquisition unit 102 acquires information related to the state of the elevator from an external device. The acquired information is used to determine whether the elevator is abnormal. In addition, the state of an elevator includes the state of the apparatus and components which comprise an elevator. In the example of FIG. 1, it is assumed that it is determined whether the raising / lowering of the car 201 is abnormal based on information acquired from the hoisting machine 204. The state may be, for example, the winding speed of the lifting cable 206, the current flowing through the hoisting machine 204, the temperature of each component, and the like.

  In addition, the abnormality detection of an elevator may be performed by the state information acquisition unit 102 or the operation control unit 104. It can be said that the part which detects the abnormality of an elevator is also an abnormality detection part. Note that an external abnormality detection device may perform the detection, and the detection result may be sent to the state information acquisition unit 102.

  The position information acquisition unit 103 acquires information related to the position of the car 201 from an external device. The acquired information is used to specify the position or range of the car 201. In the example of FIG. 1, information related to stopping or passing of the car 201 is acquired from a plurality of position detectors 212. This information makes it clear which position detector 212 the car 201 is located at (that is, the position) or between which position detectors 212 (ie, the range). The position information acquisition unit 103 or the operation control unit 104 may specify the position or range of the car 201. Alternatively, an external device such as the position detector 212 may perform the identification, and the identification result may be sent to the position information acquisition unit 103.

  The operation control unit 104 controls the operation of the elevator. For example, the operation control unit 104 controls the hoisting machine 204 and the like to control the raising / lowering of the car 201. Moreover, the operation control unit 104 changes the operation content of the elevator according to the situation. In the present embodiment, it is assumed that there are normal operation, earthquake control operation, automatic diagnosis operation, and temporary restoration operation.

  Control operation during an earthquake is an operation for safely saving a user during an earthquake. When an earthquake is detected, the operation control unit 104 switches from normal operation to seismic control operation. Due to the control operation at the time of the earthquake, the car 201 that has been moving up and down stops at the nearest floor where it can be safely stopped. Then, a user in the car 201 goes out of the car 201 (rescue operation). Further, the car 201 stands by on the stopped floor until a predetermined waiting time elapses even after the earthquake has converged. The waiting time is a time predicted to take until the shaking of the building due to the earthquake converges. It is assumed that the waiting time is determined in advance according to the magnitude of the earthquake in consideration of the characteristics of the building.

  There may be a plurality of automatic diagnosis operations. For example, there are a low speed diagnosis operation (first operation diagnosis), a high speed diagnosis operation (second operation diagnosis), a door opening / closing diagnosis operation, and the like. Other automatic diagnostic operations may be performed.

  The low-speed driving diagnosis is an automatic driving diagnosis performed when the car 201 moves up and down at a speed (first speed) lower than the rated speed of the elevator. In this description, a speed slower than the rated speed is defined as “low speed”. In the low-speed driving diagnosis, when the car 201 moves up and down at a low speed, several confirmations are made and whether an abnormality is detected. For example, normal confirmation of a device such as the position detector 212 in the hoistway 210, confirmation of the presence or absence of a collision between the car 201 and the counterweight 202 are performed. The abnormality detection is performed based on the state information. For example, the presence or absence of a collision between the car 201 and the counterweight 202 can be determined from the state of the hoisting machine 204. The space between the floors where no abnormality in the elevator is detected in the low-speed diagnosis operation is described as a low-speed operation normal section (first normal section).

  The high-speed diagnosis operation is an automatic operation diagnosis performed when the car 201 moves up and down at a speed (second speed) faster than the low speed. In this description, a speed higher than the low speed is described as “high speed”. The high speed may be a rated speed. The contents confirmed in the high-speed diagnosis operation may be the same as those in the low-speed operation diagnosis. In addition, between the floors in which the abnormality of the elevator is not detected in the high-speed diagnosis operation is described as a high-speed operation normal section (second normal section).

  The door opening / closing diagnosis operation is an automatic operation diagnosis for confirming that the doors 209 on each floor are normally opened and closed by stopping the car 201 on each floor.

  In the temporary restoration operation, the operation control unit 104 controls the elevator to operate in the usage range calculated by the usage range determination unit 105. Moreover, the raising / lowering speed of the car 201 may be controlled.

  For example, when an abnormality such as distortion occurs in the rail in the hoistway 210, the car 201 and the counterweight 202 collide when operated at high speed, but the counterweight with the car 201 when operated at low speed. There may also be a situation where 202 does not collide. In such a situation, the car 201 may be operated at a low speed. A method for determining the operation content in the temporary recovery operation will be described later.

  In the example of FIG. 1, one operation control unit 104 is shown, but the operation control unit 104 may be divided for each content of operation control. For example, the elevator control device 100 may include a normal operation control unit, an earthquake control operation control unit, an automatic diagnosis operation control unit, and a temporary restoration operation control unit.

  Further, the operation control unit 104 may provide information to an elevator user by controlling the information provider 207. The information provider 207 is a device that outputs information. The information provider 207 may be, for example, a speaker that outputs sound or a display that outputs images. The information provided by the information provider 207 is not particularly limited. For example, an available floor of the elevator, the speed of raising and lowering the car 201, the position of the car 201, and the like may be provided. Moreover, you may provide the information of the other elevator in the building where an elevator exists, etc.

  The use range determination unit 105 determines a usable range of the elevator in the temporary restoration operation. In the example of FIG. 1, the use range determination unit 105 includes a section determination unit 107 and a floor determination unit 108.

  The section determination unit 107 determines the floor between which the car 201 moves up and down in the temporary restoration operation. Hereinafter, the floor between the floors in which the car 201 is moved up and down determined by the section determination unit 107 is referred to as a use resuming section (usage section). For example, the use resumption section may be determined from the low speed operation normal section or the high speed operation normal section. The normal low-speed operation section or the high-speed operation normal section may be used as the use resumption section.

  When the use resumption section is determined, the operation control unit 104 controls the elevator so that the car 201 moves up and down in the use resumption section during the temporary restoration operation. Thereby, the use of the elevator can be resumed in a section where there is no problem even if the use is resumed.

  The floor determination unit 108 determines the floor used by the car 201 in the temporary restoration operation. Hereinafter, the floor used by the car 201 when the use of the elevator is restarted, which is determined by the floor determination unit 108, is referred to as a use resuming floor.

  The floor determination unit 108 acquires a result of opening / closing confirmation of the door 209 of each floor by the door opening / closing diagnosis operation. Then, the floor in which the door 209 is normally opened and closed is set as an available floor. For example, it is possible to enter a list of available floors for floors that are normally opened / closed of the door 209, or to indicate that the opening / closing of the door 209 is abnormal from the list of floors subject to door opening / closing diagnosis. A list of available floors may be created by deleting a new floor.

  The storage unit 106 stores information for determining the range that can be used by the usage range determination unit 105 and the available range (a usage resumption section and a usage resumption floor) determined by the usage range determination unit 105. . For example, the position where the abnormality is detected in the low-speed diagnosis operation may be stored in the storage unit 106, and the section determination unit 107 may determine the normal low-speed operation section based on the position stored in the storage unit 106. Further, the operation control unit 104 may control the lift range of the car 201 with reference to the use resumption section stored in the storage unit 106.

  Note that the information stored in the storage unit 106 is not particularly limited. Information input to each component other than the usage range determining unit 105 and information output from each component may be stored in the storage unit 106. That is, the processing result of each process may be stored in the storage unit 106, and each component may acquire the processing result with reference to the storage unit 106.

  Next, the flow of automatic diagnosis operation will be described. FIG. 2 is a schematic flowchart of automatic diagnosis performed in the present embodiment. This flow shows a case where a low speed operation diagnosis, a high speed operation diagnosis, and a door opening / closing operation diagnosis are performed. Note that this flowchart is an example, and the automatic diagnosis operation and the like to be performed are not limited to the example of FIG. The same applies to the flowcharts shown below.

  Before the automatic diagnosis operation is started, a pre-diagnosis confirmation is performed (S101). From the confirmation before diagnosis, it is determined whether or not the automatic diagnosis operation can be started, and when the automatic diagnosis operation cannot be started (NO in S102), the operation of the elevator is stopped (S103). When the automatic diagnosis operation can be started (YES in S102), the low-speed operation diagnosis is performed (S104).

  When the low-speed driving diagnosis is performed, the low-speed driving normal section is found, and when there is no low-speed driving normal section (NO in S105), the driving is stopped (S103). If there is a normal low-speed operation section, a high-speed operation diagnosis is performed in the normal low-speed operation section (S106). After completion of the high-speed driving diagnosis, a door opening / closing diagnosis is performed in the normal low-speed driving section (S107). As a result, the use resumption section and the use resumption floor, which are the use ranges in the temporary restoration operation, are determined (S107). Thus, the temporary restoration operation is started (S108), and the flow ends.

(Check before diagnosis)
FIG. 3 is a flowchart for checking before diagnosis. When it is confirmed that the user is rescued after the car 201 is stopped by the control operation during the earthquake (YES in S201), the process proceeds to the next confirmation. The confirmation may be performed by the situation information acquisition unit 101 or the like receiving a confirmation result from the monitoring person. Alternatively, the presence or absence of a person in the car 201 may be determined from an image obtained by a camera in the car 201 and a measured value such as a temperature by a sensor in the car 201.

  As described above, even after the earthquake has converged, the car 201 needs to wait on the stopped floor until a predetermined waiting time elapses. Therefore, the operation control unit 104 checks whether or not the waiting time after the earthquake has converged, and proceeds to the next process when the waiting time has elapsed (YES in S202).

  The operation control unit 104 confirms whether or not the car 201 moves normally, and if it moves normally (YES in S203), determines that the automatic diagnosis operation can be started (S204). For example, it is confirmed whether the brake of the hoisting machine 204 is normal. When it does not move normally (NO in S203), it is determined that the automatic diagnosis operation cannot be started (S205).

(Low-speed driving diagnosis)
FIG. 4 is a flowchart of the low-speed driving diagnosis. First, the operation control unit 104 controls the car 201 to move to the terminal floor of the hoistway 210, that is, the lowermost floor or the uppermost floor (S301). At that time, it may be confirmed that there is no problem in landing. The low speed driving diagnosis may be performed from the spot without moving to the terminal floor of the hoistway 210. That is, the automatic driving diagnosis may be performed from a floor that is not the terminal floor.

  The operation control unit 104 controls the car 201 to move at a low speed from one of the terminal floors to the other (S302). If the car 201 reaches the other terminal floor without detecting any abnormality (NO in S303), the section determination unit 107 determines the space between the floors in the hoistway 210, that is, from the lowest floor to the highest floor. A low speed operation normal section is determined (S304).

  On the other hand, when an abnormality is detected via the state information acquisition unit 102 (YES in S303), the section determination unit 107 identifies and records the point or range of abnormality detection (S305). For example, the identification can be performed based on the abnormality detection time from the state information acquisition unit 102 and the position information from the position information acquisition unit 103. In addition, the operation control unit 104 controls the car 201 to stop and return to the previous floor (S306). The previous floor is the floor on the lifting start side. For example, when raising / lowering from the lowest floor to the top floor is started and an abnormality is detected between the fourth floor and the fifth floor, the process returns to the fourth floor.

  When the car 201 stops at a floor other than the floor where the low speed diagnosis operation is started (YES in S307), the section determination unit 107 starts from the floor where the low speed diagnosis operation is started based on the abnormality detection record. The low-speed diagnosis normal section is determined to the floor just before the abnormality detection point, that is, between the floors that can move at a low speed (S308). On the other hand, when the car 201 is stopped at the floor where the low-speed diagnosis operation is started (NO in S307), the section determination unit 107 selects the normal section for the low-speed operation because it cannot move to the upper floor or the lower floor. Not set (S309). As a result, as shown in FIG. 2, the operation stops as a result. This completes the low-speed driving diagnosis flow.

  FIG. 5 is a diagram for explaining calculation of a normal low-speed operation section by low-speed operation diagnosis. In the example of FIG. 5, it is assumed that the car 201 descends to the first basement floor (B1), which is the final floor of the hoistway 210, and the low-speed operation diagnosis is started from the first basement floor. The arrows in FIG. 5 indicate the moving direction of the car 201, and the symbol x indicates the point where an abnormality is detected. In the example of FIG. 5, it is assumed that an abnormality is detected between the 10th floor and the 11th floor. In this assumption, since the floor immediately before is the 10th floor, the first floor to the 10th floor are determined as the low-speed diagnosis normal section.

(High-speed driving diagnosis)
FIG. 6 is a flowchart of high-speed driving diagnosis. At the end of the low-speed operation diagnosis, the car 201 is located on one terminal floor of the normal low-speed operation section. The operation control unit 104 controls the car 201 to reciprocate at a high speed in the normal low speed operation section (S401). When the car 201 reciprocates without detecting an abnormality (NO in S402), the section determining unit 107 determines the normal low speed operation section as the high speed operation normal section (S403).

  On the other hand, when an abnormality is detected via the state information acquisition unit 102 (YES in S402), the section determination unit 107 identifies and records the point or range of the forward path abnormality detection (S404). Further, the operation control unit 104 switches the speed of the car 201 to a low speed and performs control so that the remaining forward section is moved up and down at a low speed (S405). Then, when the car 201 reaches the terminal floor, the speed of the car 201 is switched to high speed, and control is performed so that the return path section moves at high speed (S406). If an abnormality is detected on the forward path, an abnormality is also detected on the return path, and the section determination unit 107 identifies and records a point or range for detecting an abnormality on the return path (S407). Then, control is performed so that the remaining return path section moves at a low speed (S408). After the completion of the movement of the return route section, the section determining unit 107 determines the high-speed operation normal section between the floors that can move at high speed (S409). Thus, the high-speed driving diagnosis flow is completed.

  FIG. 7 is a diagram for explaining calculation of a normal high-speed driving section by high-speed driving diagnosis. The leftmost bar graph in FIG. 7 shows the normal low speed operation section shown in FIG.

  The second bar graph from the left shows the speed of the high-speed driving diagnosis in the forward path. Similarly to FIG. 5, the arrow indicates the moving direction of the car 201, and the symbol x indicates the point where an abnormality is detected. In the example of FIG. 5, the car 201 stops on the 10th floor at the end of the low-speed diagnosis operation. Therefore, in the subsequent high-speed diagnosis operation, the car 201 descends from the 10th floor toward the first basement floor.

  In the example of FIG. 7, it is assumed that an abnormality is detected between the fifth floor and the sixth floor on the forward path. After the abnormality is detected, the car 201 moves at a low speed. Therefore, in this assumption, the 6th floor to the 10th floor are between the floors that can move at high speed.

  The third bar graph from the left shows the speed of the high-speed driving diagnosis on the return path. When turning back on the first basement floor, the car 201 rises at a high speed, and after an abnormality is detected again, it rises at a low speed. In the example of FIG. 7, it is assumed that an abnormality is detected between the third floor and the fourth floor on the return path. In this assumption, the section from the first basement to the third floor can be moved at high speed.

  The rightmost bar graph in FIG. 7 shows a normal section for high-speed operation calculated by high-speed operation diagnosis. Two sections, the section from the first basement to the third floor and the section from the sixth floor to the tenth floor, can be moved up and down at high speeds in the forward and return routes. The normal low speed operation section refers to the first floor to the tenth floor as before the execution of the high speed driving diagnosis, and is not limited to the fourth floor to the sixth floor that are not the normal high speed operation section.

(Door open / close diagnosis)
FIG. 8 is a flowchart of door opening / closing diagnosis. When the high-speed driving diagnosis is completed, the car 201 is located on one terminal floor of the normal low-speed driving section. The car 201 is controlled to move to the next floor in the direction from the floor toward the other terminal floor (S501). The elevator car 201 stops at the target floor, and the opening / closing of the door 209 on the floor is confirmed (S502).

  If no abnormality is detected (NO in S503), the floor determination unit 108 determines the floor as a use resuming floor (S504). After the process of S504 and when an abnormality is detected (YES in S503), the process returns to the process of S501, and the elevator car 201 moves to the next floor. Thus, when the car 201 is stopped at each floor in the normal low-speed operation section and the doors 209 on all floors in the normal low-speed operation section are confirmed to be opened and closed, the door open / close diagnosis flow ends.

(Temporary restoration operation)
FIG. 9 is a flowchart of the temporary restoration operation. The processing is performed when the predetermined automatic driving diagnosis is completed and the temporary restoration operation can be performed. Here, as shown in FIG. 2, provisional recovery operation is possible when there is a normal low-speed operation section. First, the usage range determination unit 105 determines the usage range based on the result of the automatic diagnosis operation (S601). Specifically, the section determination unit 107 determines the use resumption section from the low speed operation normal section. The use resumption floor has already been determined by the door opening / closing diagnosis.

  For example, the section determination unit 107 may set the entire low-speed operation normal section as the use resumption section. Moreover, you may determine a utilization resumption area based on the result of the high-speed driving | operation diagnosis in a low-speed driving | operation normal area. For example, in consideration of safety, a high-speed operation normal section may be used as a use resumption section. Here, the low speed operation normal section is used as the use resuming section, and the speed is switched between the high speed operation normal section and the other sections, thereby achieving both convenience and safety.

  Based on the determined usage range, the operation control unit 104 controls the equipment so that other than the usage range is not used (S602). For example, among the operation buttons that request a stop floor in the car 201, operation buttons related to floors that are not included in the use resumption section and floors that are not use resumption floors may be invalidated. Further, when the button is pressed, the information provider 207 may be provided with information indicating that the button cannot be used.

  Then, the use starts and the car 201 starts to move up and down (S603). And the raising / lowering speed of the cage | basket | car 201 is controlled so that it may become a speed according to a travel area. When the traveling section is not a high-speed operation normal section (NO in S604), the car 201 moves up and down at a low speed (S605). When the traveling section is a high-speed operation normal section (YES in S604), the car 201 moves up and down at a high speed (S605). The speed may be adjusted at an arbitrary timing and amount of fluctuation so that the speed is low in the normal low-speed operation section and high in the high-speed operation normal section.

  As described above, the operation control device controls the elevator, but the operation control device may control a plurality of elevators at the same time. For example, when one building is provided with a plurality of elevators, the operation control device controls a plurality of elevators in the same building. In this case, since the operation control device can recognize the status of the temporary restoration operation of each elevator, the information provider 207 may be controlled so as to inform the user of the status of the temporary restoration operation of each elevator.

  FIG. 10 is a diagram illustrating an example of a situation of temporary restoration operation of a plurality of elevators. In the example of FIG. 10, the use resumption section and the use resumption floor of three elevators are shown. A bar graph shows the use resumption section. YES in the bar graph indicates that the corresponding floor is a use resuming floor, and NO in the bar graph indicates that the corresponding floor is not a use resuming floor.

  The first elevator is a use resumption section from the first basement to the fifth floor. However, the 2nd and 4th floors are not resumable floors. The second elevator is a use resumption section from the first floor to the eighth floor. However, the 5th and 7th floors are not reusable floors. The third elevator is the use resumption section from the 3rd floor to the 12th floor. However, the 4th and 11th floors are not resumable floors.

  As shown in FIG. 10, there is no elevator that goes directly from the lowest floor to the highest floor. However, it is possible to go to all floors from the lowest floor to the top floor by changing three elevators. However, a user who does not recognize the use range of each elevator does not know which floor to change to which elevator to reach the target floor.

  Therefore, the operation control unit 104 confirms the use range of the controlled elevator, and in the combination of the two elevators, the floor that can be used in common, the floor that can be used only in one, and the floor that cannot be used in common Is calculated. Accordingly, it is recognized that a floor that is not used by one elevator can be reached by changing to the other elevator on the floor that is commonly used. For example, in the combination of the first elevator and the second elevator, the first floor and the third floor are derived as the floor that can be used in common, and if the transfer is performed on the first floor and the third floor, going to another floor Recognize that is possible.

  Then, the operation control unit 104 controls the information provider 207 of each elevator, so that the information provider 207 can perform elevator transfer on a common floor when resuming use of a plurality of elevators. The information of is output. Thereby, the user can change to the elevator which stops the target floor, and can improve a user's convenience.

  As described above, according to the present embodiment, even when an abnormality is detected in the elevator in the operation diagnosis performed while the use of the elevator is stopped, a section in which the use of the elevator can be resumed is detected. And the convenience of a user can be improved by restarting use of an elevator in the section concerned.

  Although one embodiment of the present invention has been described above, these embodiment are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
