  Patent Document 1 describes that in an emergency diagnosis operation by an elevator earthquake temporary restoration operation device, a car is stopped for each floor to diagnose whether there is an abnormality while opening and closing the door. . However, since the thing of patent document 1 stops operation of an elevator, when abnormality of a door is detected regardless of the content of abnormality, even if the abnormality is a minor failure, it is inspected by a specialist engineer. The elevator will stop operating until it is received. When a wide-area earthquake occurs, the amount of work becomes excessive, inspection by specialist engineers is not in time, and the elevator is stopped for a long time. Therefore, there is a problem that convenience of the elevator is lowered.

The earthquake diagnostic operation command section moves the car at a predetermined speed and stops it at each floor when the first seismic sensor of the first seismic sensor and the second seismic sensor operates. In addition, we will conduct an earthquake diagnosis operation to diagnose the damage of the elevator device due to shaking. The earthquake door open / close operation command section opens and closes the car door when the car is stopped on each floor during the earthquake diagnosis operation. The door abnormality detection unit acquires information indicating a traveling state of the door of the car and detects a door abnormality based on the information. The temporary restoration operation command unit during an earthquake, when the door abnormality detection unit detects a predetermined failure as a car door abnormality, decelerates the door opening / closing speed by the door opening / closing operation command unit during an earthquake. Temporarily restore the elevator system to normal operation.

  The control method for an elevator apparatus according to one aspect of the present invention includes a first earthquake sensor that operates when a shake exceeding a first reference value is detected, and a second reference that is greater than the first reference value. Among the second seismic detectors that operate when a shake exceeding the value is detected, when the first seismic detector is activated, the seismic diagnostic operation command unit moves the car at a predetermined speed and each floor And a process of performing an earthquake diagnostic operation for diagnosing damage to the elevator device due to shaking. In addition, the elevator device control method is based on the door opening / closing operation command unit at the time of the earthquake, when the car stops at each floor during the earthquake diagnostic operation, and the door abnormality detection is detected. And a process of acquiring information indicating a door state of the car by the unit and detecting an abnormality of the door based on the information. Furthermore, the elevator apparatus control method is such that when the door abnormality detection unit detects a predetermined failure as an abnormality of the car door by the temporary restoration operation command unit during an earthquake, the door opening / closing operation command unit during an earthquake And a process of temporarily restoring the elevator apparatus to a normal operation state after decelerating the opening / closing speed and performing a temporary restoration operation during an earthquake.

According to at least one aspect of the present invention, even if an abnormality is detected in a car door during an earthquake diagnosis operation after the occurrence of an earthquake, if the door abnormality is a predetermined failure, a high speed diagnosis operation during an earthquake is performed. Continue. If no other abnormality is detected, the normal operation state is temporarily restored with the opening / closing speed of the car door being reduced (temporary restoration operation during an earthquake). In this way, after the earthquake occurs, diagnostic operation is performed during the earthquake, and when the running state of the door meets certain conditions, temporary restoration operation during the earthquake is carried out, thereby securing the means for moving the elevator device user This improves the convenience for the user.

  In addition, the car 1 includes a plurality of door rollers 15 that are wheels for moving the door hangers 12 a and 12 b attached to the door hangers 12 a and 12 b, and a range in which the door roller 15 moves on the upper surface of the car 1. And a laid door rail 16. The car 1 further includes a door motor 17, a door opening / closing speed detection device 18, and a car door control device 19 that controls the door motor 17.

  The door motor 17 has a rotating shaft portion fixed to the driving roller 14a, drives the belt 13 by rotating the rotating shaft portion and rotating the driving roller 14a, and the car doors 11a and 11b and the door hanger 12a, 12b is opened and closed. Hereinafter, opening and closing the car doors 11a and 11b and the door hangers 12a and 12b will be described as opening and closing the car doors 11a and 11b.

  The door opening / closing speed detector 18 (an example of a door opening / closing speed detector) detects the rotation speed of the car doors 11a and 11b by detecting the rotation of the rotating shaft portion fixed to the drive roller 14a on which the belt 13 is suspended. Traveling speed) is detected. For the door opening / closing speed detection device 18, for example, a rotary encoder that detects the rotation speed of the rotary shaft portion fixed to the drive roller 14a is used. The door opening / closing speed detection device 18 detects the opening / closing speeds of the car doors 11a and 11b, and outputs a detection signal corresponding to the traveling speed of the car doors 11a and 11b to the car door control device 19. The car door control device 19 outputs a detection signal corresponding to the traveling speed of the car doors 11 a and 11 b received from the door opening / closing speed detection device 18 to the elevator control device 6. The detection signal output by the door opening / closing speed detection device 18 is an example of information indicating a traveling state of the car doors 11a and 11b described later.

[Internal configuration of elevator controller]
The elevator control device 6 includes an earthquake control operation control device 61 that is activated when either the low-gal earthquake detector 8 or the high-gal earthquake detector 9 is operated, and an earthquake that performs temporary restoration operation at the time of the earthquake of the elevator device 100. A temporary recovery operation control device 62 is provided.

  The earthquake temporary restoration operation control device 62 includes an earthquake low speed diagnosis operation command unit 62a, an earthquake high speed diagnosis operation command unit 62b, an earthquake door open / close operation command unit 62c, an earthquake temporary restoration operation command unit 62d, and a door abnormality detection. Each command unit of the unit 62e and a memory 62f are provided.

  The earthquake low speed diagnosis operation command unit 62a and the earthquake high speed diagnosis operation command unit 62b are components of the earthquake diagnosis operation command unit. When the low-gal earthquake detector 8 operates, the earthquake diagnosis operation command unit moves the car 1 at a predetermined speed and stops it at each floor to diagnose damage to the elevator apparatus 100 due to shaking (earthquake). Perform diagnostic operation during earthquakes. The earthquake diagnosis operation includes an earthquake low speed diagnosis operation by the earthquake low speed diagnosis operation command section 62a and an earthquake high speed diagnosis operation by the earthquake high speed diagnosis operation command section 62b.

  The earthquake low speed diagnosis operation command unit 62a performs an earthquake low speed diagnosis operation for diagnosing damage to the elevator apparatus 100 by causing the car 1 to travel at a low speed.

  When there is no abnormality in the earthquake low speed diagnosis operation, the earthquake high speed diagnosis operation command unit 62b causes the car 1 to travel at a high speed to cause damage to the elevator apparatus 100 (an abnormality in the car doors 11a and 11b of the car 1). ) Earthquake high-speed diagnostic operation is performed.

  The earthquake door opening / closing operation command unit 62c performs an opening operation or a closing operation of the car doors 11a and 11b of the car 1 during the earthquake diagnosis operation. That is, the door opening / closing operation command unit 62c at the time of the earthquake follows the command of the low speed diagnosis operation command unit 62a at the time of earthquake, the high speed diagnosis operation command unit 62b at the time of earthquake, or the temporary restoration operation command unit 62d at the time of earthquake. , 11b are opened or closed.

  The temporary restoration operation command unit 62d during an earthquake performs the temporary restoration operation during an earthquake of the elevator apparatus 100 when a certain condition for the temporary restoration operation during the earthquake of the elevator apparatus 100 is satisfied. For example, when a predetermined failure is detected as an abnormality of the car doors 11a and 11b of the car 1, the earthquake temporary restoration operation command unit 62d decelerates the opening and closing speed of the car doors 11a and 11b and then lifts the elevator. The apparatus 100 is temporarily restored to a normal operating state, and a temporary restoration operation during an earthquake is performed.

  The door abnormality detection unit 62e acquires information indicating the traveling state of the car doors 11a and 11b of the car 1 from the car door control device 19, and the car door is based on the information indicating the traveling state of the car doors 11a and 11b. Abnormalities of opening and closing of 11a and 11b are detected. The detection result of the door abnormality detection unit 62e is output to the door opening / closing operation command unit 62c during an earthquake. In this embodiment, the door abnormality detection unit 62e detects the opening / closing speed of the car doors 11a, 11b detected by the door opening / closing speed detection device 18, and the reference value (reference opening / closing speed) of the opening / closing speed of the car doors 11a, 11b. Compare And the door abnormality detection part 62e detects a predetermined | prescribed failure as abnormality of the car doors 11a and 11b based on the comparison result. The reference opening / closing speed is, for example, the door opening / closing speed commanded to the door motor 17 from the door opening / closing operation command unit 62c during an earthquake. The predetermined failure is intended to be a minor failure that can be performed by operating the car itself and opening and closing the car door itself.

  As a condition for determining whether or not the above-mentioned minor failure has occurred, there are a first condition and a second condition as an example, and the detected opening / closing speeds of the car doors 11a and 11b do not satisfy the first condition and the second condition. When the above condition is satisfied, the detected abnormality is defined as a minor failure. Here, the first condition is that the detected opening / closing speed of the car doors 11a, 11b ranges from a first speed lower limit value that is slower than the reference opening / closing speed to a first speed upper limit value that is faster than the reference opening / closing speed (first Is included in the target range). If the detected opening / closing speed is within the first target range, the detected opening / closing speed is a normal value.

  The second condition is that the detected opening / closing speed of the car doors 11a and 11b is faster than the second speed lower limit value from the second speed lower limit value that is slower than the first speed lower limit value. It is included in the range (second target range) of the second speed upper limit value that is slower than the lower limit value. That is, the second condition is that the detected opening and closing speeds of the car doors 11a and 11b are included in the second target range having a value slower than the first speed lower limit value as the second speed upper limit value.

  The memory 62f stores a threshold value used for determining whether the car doors 11a and 11b are opened / closed abnormally or a minor failure by the door abnormality detecting unit 62e. In the present embodiment, the first speed lower limit value and the first speed upper limit value as threshold values are set to 80% and 120% of the reference opening / closing speed, respectively, and the second speed lower limit value and the second speed upper limit value are set. The value is set to 50% and 80% of the reference opening / closing speed. In the present embodiment, when the traveling speed of the car doors 11a and 11b is within the range of 80% to 120% of the reference opening / closing speed (first target range), the traveling state of the car doors 11a and 11b is normal. It is judged that. In the present embodiment, when the traveling speed of the car doors 11a and 11b is within the range (second target range) of 50% or more and less than 80% of the reference value, the traveling state of the car doors 11a and 11b is abnormal. Is considered a minor failure. This threshold value is an example, and the definition of door opening / closing abnormality and minor failure is not limited to this example.

  In this embodiment, the detection signal output from the door opening / closing speed detection device 18 is used as information indicating the traveling state of the car doors 11a and 11b. However, the torque value of the door motor 17 may be used. . For example, a torque measuring unit for measuring the torque of the door motor 17 is provided, and the torque value measured during the high-speed diagnostic operation is compared with the torque threshold value for detecting the abnormality of the car doors 11a and 11b, and the comparison result is used as a basis. An abnormality in the car doors 11a and 11b may be detected.

  The door abnormality detection unit 62e compares information (traveling state information) indicating the traveling state of the car doors 11a and 11b acquired from the car door control device 19 with the threshold value stored in the memory 62f, and compares the information on the car doors 11a and 11b. Detect opening and closing abnormalities.

[Example computer hardware configuration]
Next, the hardware configuration of the computer 50 constituting the elevator control device 6 shown in the elevator device 100 described above will be described.

  In the present embodiment, the elevator monitoring device 21, the monitoring center 23, and the car door control device 19 have the same hardware configuration as the computer 50. However, each part of the computer 50 is selected according to the function and usage purpose of each apparatus.

FIG. 3 shows a hardware configuration example of the computer 50.
The computer 50 is hardware used as a so-called computer. The computer 50 includes a CPU (Central Processing Unit) 51, a ROM (Read Only Memory) 52, and a RAM (Random Access Memory) 53 connected to the bus 54. Further, the computer 50 includes a display unit 55, an operation unit 56, a nonvolatile storage 57, and a network interface 58.

  The CPU 51 reads out the program code of software that implements each function according to the present embodiment from the ROM 52 and executes it. That is, when the CPU 51 executes the program code read from the ROM 52, the functions of the seismic control operation control device 61 and the earthquake temporary restoration operation control device 62 are realized. The computer 50 may include a processing device such as an MPU (Micro-Processing Unit) instead of the CPU 51.

  In the RAM 53, variables, parameters, and the like generated during the arithmetic processing are temporarily written. The display unit 55 is, for example, a liquid crystal display monitor, and displays the results of processing performed by the computer 50 to the operator. For example, a keyboard, a mouse, or the like is used for the operation unit 56, and an operator can perform predetermined operation inputs and instructions.

  Examples of the non-volatile storage 57 include a hard disk drive (HDD), a solid state drive (SSD), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, and a non-volatile memory card. Used. In addition to the OS (Operating System) and various parameters, the nonvolatile storage 57 stores a program for causing the computer 50 to function. For example, a network interface card (NIC) or the like is used as the network interface 58, and various types of data can be transmitted to and received from the elevator monitoring device 21 and the like via a network N such as a LAN.

  2 is realized by the ROM 52 or the nonvolatile storage 57.

[Elevator control method]
FIG. 4 is a flowchart showing a temporary restoration operation process as one form of a control method for the elevator apparatus 100.

  First, the seismic control operation control device 61 monitors the operations of the low-gal earthquake sensor 8 and the high-gal earthquake sensor 9 (S1). The seismic control operation control device 61 performs seismic control operation when detecting that the low-gal seismic detector 8 is operated. At this time, if the earthquake is a small earthquake in which the high-gal earthquake sensor 9 does not operate (YES in S1), the information is output to the temporary restoration operation control device 62 at the time of earthquake.

  Next, the earthquake temporary restoration operation command unit 62d of the earthquake temporary restoration operation control device 62 determines whether or not the earthquake temporary restoration operation is possible (S2). For example, as a condition that enables temporary restoration operation during an earthquake, at least the inside of the car 1 is unmanned, and further, other predetermined abnormality is not detected.

  In the case of a large earthquake in which the high gal earthquake detector 9 operates (NO in S2), the seismic control operation control device 61 detects that the high gal earthquake detector 9 has operated (S3). . In this case, since damage is assumed to the elevator apparatus 100, the seismic control operation control apparatus 61 performs control such as stopping the car 1 at the nearest floor and stops the operation of the elevator apparatus 100 (S4). . And after inspection of the elevator apparatus 100 by a professional engineer is implemented (S15), the earthquake control operation control apparatus 61 returns the elevator apparatus 100 to normal operation (normal operation state) (S16). When the elevator apparatus 100 is returned to the normal operation, this process ends.

  When the earthquake temporary restoration operation is impossible in step S2 (S2 is impossible), the earthquake temporary restoration operation command unit 62d proceeds to the process of step S4.

  On the other hand, when the temporary restoration operation at the time of earthquake is possible in step S2 (possible at S2), the temporary restoration operation command unit 62d at the time of the earthquake takes the car until a predetermined time elapses after the low-gal earthquake detector 8 operates. It waits while confirming that the inside of 1 is unmanned (S5). When the predetermined time has not elapsed (NO in S5), the earthquake temporary restoration operation command unit 62d returns to the determination process in step S2.

  Whether the car 1 is unmanned can be confirmed by, for example, the detection result of a load detection device (not shown) provided in the car 1 or the presence / absence of operation of a call button in the car 1. The reason for waiting for the elapse of the predetermined time is that it is necessary to wait for the shaking of the control cable 6a, the rope 5, and the governor rope (not shown) due to the earthquake to settle.

  When the predetermined time has elapsed in step S5 (YES in S5), the earthquake temporary restoration operation command unit 62d operates the reset coil 10 to reset the low-gal earthquake detector 8 (S6).

  Thereafter, the earthquake temporary restoration operation control device 62 performs an earthquake diagnostic operation to diagnose damage to the elevator apparatus 100 due to the earthquake.

  First, the car low speed diagnosis operation command unit 62a closes the car doors 11a and 11b and causes the car 1 to run at a low speed from the lowest floor to the highest floor to check whether there is any abnormality (S7). For example, it is determined by measuring the torque value of the motor 7 whether or not the rope 5, the control cable 6 a, the not-illustrated compen- sion rope and the governor rope are caught on the projections in the tower. If there is an abnormality (the abnormality in S7), damage to the elevator apparatus 100 is assumed. Therefore, the earthquake low speed diagnosis operation command unit 62a outputs the diagnosis result to the earthquake control operation control device 61, and the earthquake control operation control device 61 stops the operation of the elevator apparatus 100 in response to the diagnosis result with an abnormality ( Step S4). And after inspecting the elevator apparatus 100 by a professional engineer (S15), the earthquake control operation control apparatus 61 returns the elevator apparatus 100 to normal operation (S16).

  Next, when there is no abnormality in step S7 (no abnormality in S7), the car high speed diagnosis operation command unit 62b closes the car doors 11a and 11b and moves the car 1 from the lowest floor to the highest floor at high speed. Then, each floor is operated to check whether there is any abnormality (S8). Here, for example, whether or not there is an abnormality in a position detection device (not shown) that detects the position of the car 1 is checked. When there is an abnormality (the abnormality is S8), the earthquake high-speed diagnosis operation command unit 62b outputs the diagnosis result to the earthquake control operation control device 61. The seismic control operation control device 61 stops the operation of the elevator device 100 in response to the diagnosis result of abnormality (step S4).

  Next, if there is no abnormality in step S8 (no abnormality in S8), the car doors 11a and 11b are closed by the earthquake high-speed diagnosis operation command unit 62b, and the car 1 runs at a high speed from the lowest floor to the highest floor. At each floor. Then, the high-speed diagnostic operation command unit 62b during an earthquake checks whether there is no abnormality by opening and closing the car doors 11a and 11b only by stopping the car 1 at each floor (S9).

  For example, the earthquake high-speed diagnosis operation command unit 62b determines that the car door 11a, 11b, when the traveling speed of the car door 11a, 11b is within a range (first target range) of 80 to 120% of the command opening / closing speed (reference opening / closing speed). , 11b is determined to be normal.

  If there is no abnormality in step S9 (no abnormality of S9), the earthquake temporary restoration operation command unit 62d temporarily restores the elevator apparatus 100 to a normal operating state and performs an earthquake temporary restoration operation (S10). .

  Here, the temporary restoration operation command unit 62d during an earthquake displays a message such as “Temporary restoration operation during an earthquake” on the screen of the display device 1A (notification unit) of the car 1, for example. The passenger is informed that the vehicle is being restored (S11). Thereafter, when the inspection of the elevator apparatus 100 is performed by a specialist engineer, the earthquake control operation control apparatus 61 returns the elevator apparatus 100 to normal operation (S15, S16).

  On the other hand, when there is an abnormality in step S9 (there is an abnormality in S9), the earthquake high-speed diagnostic operation command unit 62b determines whether or not the abnormality of the car doors 11a and 11b is a minor failure (S12). For example, the earthquake high-speed diagnostic operation command unit 62b determines that the abnormality of the car doors 11a and 11b is not a minor failure when the traveling speed of the car doors 11a and 11b is less than 50% or more than 120% of the command opening / closing speed. (NO in S12). The earthquake high-speed diagnostic operation command unit 62b outputs the determination result to the seismic control operation control device 61, and the seismic control operation control device 61 stops the operation of the elevator apparatus 100 in response to the determination result that there is no minor failure ( Step S4).

  On the other hand, when the abnormality of the car doors 11a and 11b is a minor failure in step S12 (YES in S12), the earthquake high-speed diagnosis operation command unit 62b continues the earthquake high-speed diagnosis operation. For example, the high speed diagnostic operation command unit 62b during an earthquake causes the car doors 11a and 11b to be used when the traveling speed of the car doors 11a and 11b is 50% or more and less than 80% (within the second target range) of the command opening / closing speed. Is determined to be a minor failure.

  If only minor malfunctions are detected as a result of detecting the opening / closing abnormality of the car doors 11a and 11b in all the floors, the temporary restoration operation command unit 62d at the time of the earthquake is connected to the car doors 11a and 11b. Temporary restoration operation at the time of earthquake is carried out by limiting the opening and closing speed (S13). The earthquake temporary restoration operation command unit 62d instructs the door opening / closing operation command unit 62c during the earthquake to decelerate the opening / closing speed of the car doors 11a, 11b to a predetermined speed or less (for example, half of the reference opening / closing speed). The apparatus 100 is temporarily restored to normal operation. Note that it is arbitrary how much the opening / closing speed of the car doors 11a and 11b is reduced during the temporary restoration operation during an earthquake.

  Then, the earthquake temporary restoration operation command unit 62d displays a message such as “Temporary restoration operation during earthquake” on the screen of the display device 1A (notification unit) of the car 1 to temporarily restore during the earthquake. The passenger is informed that it is driving (S14). At this time, for example, a message such as “Closing the opening / closing speed of the car door” is displayed on the display device 1A to notify the passenger that the door opening / closing speed is being reduced. With this message, the passenger can use the elevator apparatus 100 after recognizing that the opening / closing speed of the car door is different from usual. Along with the message display, the same content may be notified to the passenger by voice. Thereafter, when the inspection of the elevator apparatus 100 is performed by a specialist engineer, the earthquake control operation control apparatus 61 returns the elevator apparatus 100 to normal operation (S15, S16).

  In this manner, the earthquake door opening / closing operation command unit 62c transmits the door opening / closing command and the opening / closing command speed to the car door control device 19 at the time of the high-speed diagnosis operation (each floor operation and door opening / closing) in Step S9. The car door control device 19 operates the door motor 17 in accordance with the received door opening / closing command. At this time, the car doors 11 a and 11 b and the door hangers 12 a and 12 b are opened and closed by the rotation of the door motor 17 through the belt 13. The door opening / closing speed detection device 18 detects the driving speed of the belt 13 as the opening / closing speeds of the car doors 11a and 11b and the door hangers 12a and 12b, and outputs them to the door abnormality detection unit 62e via the car door control device 19. .

  At this time, if the car doors 11a and 11b are normal, there is no difference between the command opening / closing speed commanded by the door opening / closing operation command unit 62c during earthquake and the detection opening / closing speed of the door opening / closing speed detecting device 18. However, for example, when the car doors 11a and 11b, the door hangers 12a and 12b, the door rail 16, and the building where the elevator apparatus 100 is installed are deformed due to an earthquake, the command issued by the earthquake door opening / closing operation command unit 62c A difference appears between the opening / closing speed and the opening / closing speed detected by the door opening / closing speed detector 18.

  In such a case, if the doors of the car doors 11a and 11b are opened and closed at a normal speed, a considerable squeaking noise may be generated and the abnormal state may be worsened. The passenger convenience is greatly impaired. Therefore, when the difference between the command opening / closing speed and the detected opening / closing speed satisfies a certain condition, the earthquake high speed diagnostic operation command unit 62b determines that the car doors 11a and 11b are minor failures (corresponding to YES in S12). Implement temporary restoration operation in the event of an earthquake. Further, the earthquake high-speed diagnostic operation command unit 62b transmits the fact from the elevator control device 6 to the elevator monitoring device 21.

The elevator monitoring device 21 notifies the monitoring center 23 of a minor failure state via the telephone line 22. The monitoring center 23 grasps the abnormality content of the elevator apparatus 100 and identifies the abnormal part. For example, if the abnormality is related to the operation of the car 1, the operation speed of the elevator apparatus 100 is reduced. If the abnormality is related to the door opening / closing, the door opening / closing speed is reduced, thereby limiting the function. Do not pause as much as possible. Thereby, it can contribute to the reduction of the downtime of the elevator apparatus 100 at the time of a wide area earthquake occurrence, and the burden reduction of a professional engineer.
In response to the command from the monitoring center 23, the elevator control device 6 restricts the command opening / closing speed for the car doors 11a and 11b to a constant speed. The car door control device 19 performs a temporary restoration operation at the time of an earthquake after implementing measures for limiting the rotation speed of the door motor 17 (corresponding to step S13).

  Depending on the deformation state of the car 1 at the time of the earthquake, even if the door opening / closing operation command unit 62c at the time of the earthquake commands the door opening / closing speed, the door motor 17 does not rotate, and the door opening / closing speed detecting device 18 is in contact with the car door 11a. , 11b may not be detected. Since such an abnormality of the car doors 11a and 11b is not a minor failure, the operation of the elevator apparatus 100 is suspended.

[Effect of one embodiment]
In the embodiment configured as described above, the earthquake high-speed diagnostic operation command unit 62b opens and closes the car doors 11a and 11b by stopping the car 1 on each floor at high speed during the earthquake high-speed diagnostic operation. The car doors 11a and 11b are detected to be opened or closed abnormally. And if the opening / closing abnormality of the car doors 11a, 11b is detected, the detected contents are analyzed, and if it is determined that the failure is a minor failure based on the analysis result, the high-speed diagnostic operation at the time of earthquake is continued. If no other abnormality is detected, the earthquake temporary restoration operation command unit 62d temporarily restores the elevator apparatus 100 to a normal operating state with the opening / closing speed of the car doors 11a and 11b being reduced (at the time of an earthquake). Temporary recovery operation). As described above, after the earthquake occurs, the earthquake diagnostic operation is performed, and when the door traveling condition satisfies a certain condition, the temporary recovery operation at the time of the earthquake is performed, thereby securing the moving means for the user of the elevator apparatus 100. It becomes possible to do. Therefore, user convenience is improved.

  Moreover, in one Embodiment mentioned above, the elevator control apparatus 6 transmits that the minor failure was detected to the monitoring center 23 etc., when the minor failure of the cars 11a and 11b was detected as a door opening / closing abnormality. Therefore, the specialist engineer can preferentially check the status of the car doors 11a and 11b after arrival at the site.
