Embodiment 1 FIG.
1 is a block diagram showing an elevator apparatus according to Embodiment 1 of the present invention. In the figure, an elevator apparatus includes an earthquake detector 1 for detecting an earthquake, a fire fighting operation switch apparatus 2 for performing a fire fighting operation, and an abnormality diagnosis apparatus for diagnosing an abnormality in the elevator apparatus when performing an automatic diagnosis operation during an earthquake. 3 and a control device 4 for controlling the operation of the elevator apparatus. Under the control of the control device 4, the elevator apparatus switches between an earthquake control operation, an earthquake automatic diagnosis operation, a fire fighting operation, a normal operation, and an operation suspension.

  The earthquake detector 1 senses the shaking of the building where the elevator apparatus is installed. The earthquake detector 1 is installed, for example, in an elevator machine room or a hoistway pit. The earthquake detector 1 outputs earthquake information to the control device 4 when it detects an earthquake.

  The fire-fighting operation switch device 2 is installed in an elevator car. The fire fighting operation switch device 2 has a primary fire fighting switch 21 and a secondary fire fighting switch 22 that are operated during a fire fighting. When the primary fire fighting switch 21 is operated, the fire fighting operation switch device 2 outputs primary fire fighting information indicating that the primary fire fighting switch 21 has been operated to the control device 4. Further, when the secondary fire fighting switch 22 is operated, the fire fighting operation switch device 2 outputs secondary fire fighting information indicating that the secondary fire fighting switch 22 has been operated to the control device 4.

  The abnormality diagnosis device 3 is an abnormality that cannot perform a firefighting operation when the elevator apparatus performs an automatic diagnosis operation during an earthquake, and a normal operation impossible abnormality that can perform a firefighting operation but cannot perform a normal operation. The presence or absence of each is diagnosed. The fire-fighting operation impossibility abnormality is a serious abnormality and includes, for example, hoisting machine torque abnormality, end point switch abnormality, landing device abnormality, and the like. The normal operation impossibility abnormality is a minor abnormality, for example, occurrence of abnormal noise or abnormal vibration when the elevator car is raised or lowered, or abnormality in the door opening / closing speed. The abnormality diagnosis device 3 outputs the diagnosis result to the control device 4.

  When the earthquake information is input from the earthquake detector 1, the control device 4 operates so that the elevator device performs a control operation during an earthquake.

  In addition, the control device 4 operates so that the elevator apparatus performs an automatic diagnosis operation during an earthquake after the control operation during an earthquake is performed. In the automatic diagnosis operation during an earthquake, the control device 4 causes the car to travel in the order of ultra-low speed travel, low speed travel, and rated speed travel, and causes the abnormality diagnosis device 3 to diagnose an abnormality in the elevator device.

  In addition, when the abnormality diagnosis device 3 diagnoses that there is an abnormality that disables the fire fighting operation, the control device 4 stops the operation of the elevator device.

  Further, the control device 4 is a case where the abnormality diagnosis device 3 diagnoses that there is no abnormality that prevents fire fighting operation, and when primary fire fighting information or secondary fire fighting information is input from the fire fighting operation switch device 2, that is, fire fighting operation. Is requested, the elevator apparatus operates to perform the fire fighting operation. As a specific example of fire fighting operation, when primary fire fighting information is input, the control device 4 invalidates the landing call, and even if a landing call is made on each floor, it directly goes to the destination floor without responding to it. On the other hand, when the secondary fire fighting information is input, the control device 4 invalidates the detection result of the landing door open detection device, and even if the elevator car or the landing door is not in the door closed position, The elevator car can run.

  Further, the control device 4 is a case where the abnormality diagnosis device 3 diagnoses that there is neither a fire-fighting operation failure abnormality nor a normal operation failure abnormality, and both the primary fire-fighting information and the secondary fire-fighting information are sent from the fire-fighting operation switch device 2. When no input is made, that is, when fire fighting operation is not requested, the control device 4 operates so that the elevator device performs normal operation.

  Further, the control device 4 is a case where the abnormality diagnosis device 3 diagnoses that there is no abnormality that prevents firefighting operation and there is an abnormality that prevents normal operation, and inputs both primary firefighting information and secondary firefighting information from the firefighting operation switch device 2. If not, that is, if fire fighting operation is not requested, the elevator apparatus is stopped.

  Next, the operation method of an elevator apparatus is demonstrated. First, the earthquake automatic diagnosis operation of the elevator apparatus when fire fighting operation is not requested will be described. When fire control operation is not requested and the control operation during an earthquake ends, the elevator apparatus performs an automatic diagnosis operation during an earthquake for each of the abnormalities that prevent the fire operation and the normal operation (an automatic diagnosis operation process during an earthquake). The automatic diagnosis operation at the time of earthquake for each of the fire-fighting failure and the normal operation failure is performed simultaneously.

  Next, the operation of the elevator apparatus after the earthquake automatic diagnosis operation is completed will be described. FIG. 2 is a flowchart showing the operation of the elevator apparatus after the earthquake automatic diagnosis operation is completed. First, the control device 4 determines whether there is a fire-fighting operation failure abnormality or a normal operation failure failure based on the diagnosis result of the abnormality diagnosis device 3 (step S101). When the control device 4 determines that neither the fire-fighting operation failure abnormality nor the normal operation failure abnormality is found in step S101, the elevator apparatus performs normal operation (resumption of operation) (normal operation process) (step S102). Thereafter, the control device 4 determines whether or not there is a request for fire fighting operation (step S103).

  When the control device 4 determines that there is a request for fire fighting operation in step S103, the elevator device starts fire fighting operation (fire fighting operation step) (step S104), and then the elevator device ends the fire fighting operation (step S104). After that, the elevator apparatus performs normal operation (resumption of operation) (normal operation process) (step S106). In step S103, when the control device 4 determines that there is no request for fire fighting operation, the elevator apparatus continues normal operation.

  On the other hand, when the control device 4 determines in step S101 that there is a fire-fighting operation impossibility abnormality or a normal operation impossibility abnormality, the control device 4 determines whether there is a fire-fighting operation impossibility abnormality based on the diagnosis result of the abnormality diagnosis device 3. Is determined (step S107). If the control device 4 determines in step S107 that there is an abnormality that disables firefighting operation, the elevator device is disabled (operation suspension) for firefighting operation (operation suspension step) (step S108).

  On the other hand, when the control device 4 determines in step S107 that there is no fire-fighting operation failure abnormality, the control device 4 determines whether there is a request for fire-fighting operation (step S109).

  When the control device 4 determines that there is a request for fire fighting operation in step S109, the elevator device starts fire fighting operation (fire fighting operation process) (step S110), and then the elevator device finishes fire fighting operation (step S110). After that, the elevator apparatus is put into an operation stop (operation stop process) (step S112).

  If the control device 4 determines in step S109 that there is no request for fire fighting operation, the process proceeds to step S112.

  Next, the operation of the elevator apparatus when there is a request for firefighting operation during the automatic diagnosis operation during an earthquake will be described. FIG. 3 is a flowchart showing the operation of the elevator apparatus when there is a request for firefighting operation during the automatic diagnosis operation during an earthquake. First, when the control operation at the time of earthquake ends, the elevator apparatus starts an automatic diagnosis operation at the time of earthquake (automatic diagnosis operation process at the time of earthquake) (step S201).

  When there is a request for firefighting operation in the automatic diagnosis operation process during earthquake (step S202), the elevator apparatus interrupts the automatic diagnosis operation during earthquake (step S203), and then the elevator apparatus performs an earthquake only for abnormalities that are impossible for firefighting operation. Time automatic diagnosis operation is performed (fire-fired operation failure abnormality diagnosis operation process) (step S204). That is, the abnormality diagnosis device 3 diagnoses by giving priority to the presence or absence of the fire-fighting operation impossibility over the presence or absence of the normal operation impossibility abnormality. At this time, the elevator apparatus performs an automatic diagnosis operation during an earthquake by increasing the traveling speed of the elevator car from the normal traveling speed.

  After the earthquake automatic diagnosis operation in step S204 is completed, the control device 4 determines whether there is a fire-fighting operation failure abnormality based on the diagnosis result of the abnormality diagnosis device 3 (step S205). If the control device 4 determines in step S205 that there is an abnormality that disables firefighting operation, the elevator apparatus is disabled from firefighting operation (operation suspension) (operation suspension process) (step S206).

  On the other hand, if the control device 4 determines in step S205 that there is no abnormality that disables firefighting operation, the elevator apparatus performs firefighting operation (firefighting operation process) (step S207).

  After the fire fighting operation in step S207 is completed, the elevator apparatus performs an automatic diagnosis operation during an earthquake for a normal operation impossibility abnormality that has not been diagnosed yet (normal operation impossibility abnormality operation step) (step S208).

  After the earthquake automatic diagnosis operation in step S208 is completed, the control device 4 determines whether or not there is an abnormality in normal operation based on the diagnosis result of the abnormality diagnosis device 3 (step S209). If the control device 4 determines in step S209 that there is an abnormality that prevents normal operation, the elevator device is suspended (step S210).

  On the other hand, if the control device 4 determines in step S209 that there is no abnormality in normal operation, the elevator device performs normal operation (normal operation process) (step S211).

  As described above, according to the elevator apparatus according to the first embodiment of the present invention, when the fire-fighting operation switch apparatus 2 that is required to operate the fire-fighting operation and the automatic diagnosis operation during an earthquake are performed, the fire-fighting operation is performed. An abnormality diagnosis device 3 for diagnosing the presence / absence of each of the abnormalities that are impossible to drive and the abnormalities of normal operation is provided. When the fire diagnosis operation is requested when the abnormality diagnosis device 3 makes a diagnosis, the fire diagnosis operation is performed. Therefore, in the automatic diagnosis operation at the time of earthquake, the fire operation can be performed but the normal operation cannot be performed. If a minor abnormality is detected, the elevator apparatus can perform the fire fighting operation when the fire fighting operation is requested. As a result, the elevator apparatus can perform fire fighting more reliably.

  In addition, the abnormality diagnosis device 3 diagnoses by giving priority to the presence or absence of fire-fighting operation impossibility over the presence or absence of fire-fighting operation impossibility when fire-fighting operation is requested during the automatic diagnosis operation during an earthquake. It is possible to diagnose the presence or absence of fire-fighting operation failure abnormality more quickly. As a result, the elevator apparatus can start the fire fighting operation earlier.

  In addition, since the elevator apparatus performs normal operation when the abnormality diagnosis device 3 diagnoses that there is neither a fire-fighting operation impossibility abnormality nor a normal operation impossibility abnormality, and the fire-fighting operation is not requested, the elevator apparatus performs normal operation. After driving, a general user can use the elevator apparatus.

  In addition, the elevator apparatus is in a case where the abnormality diagnosis device 3 diagnoses that there is no abnormality that prevents firefighting operation and there is an abnormality that does not allow normal operation. When there is, it can prevent that a general user uses an elevator apparatus.

  Moreover, according to the operation method of the elevator apparatus which concerns on Embodiment 1 of this invention, when the abnormality diagnosis apparatus 3 diagnoses that there exists an automatic diagnosis operation process at the time of earthquake which performs automatic diagnosis operation at the time of an earthquake, and a fire-fighting operation impossibility abnormality Is equipped with a fire-stop operation in which the fire-fighting operation is performed when the abnormality diagnosis device 3 diagnoses that there is no abnormality that prevents fire-fighting operation and fire-fighting operation is requested. Therefore, in the automatic diagnosis operation at the time of earthquake, when an abnormality that can perform fire fighting operation but cannot perform normal operation is detected, the elevator apparatus performs fire fighting operation by requesting fire fighting operation. It can be carried out. As a result, the elevator apparatus can perform fire fighting more reliably.

  Also, when fire-fighting operation is requested in the automatic diagnosis operation process at the time of earthquake, the abnormality diagnosis device 3 gives priority to the presence or absence of a fire-fighting operation impossibility over the presence or absence of normal operation impossibility abnormality. It is possible to quickly diagnose the presence or absence of abnormalities. As a result, the elevator apparatus can start the fire fighting operation earlier.

  In addition, although the said Embodiment 1 demonstrated the structure which an elevator apparatus performs a normal driving | operation after an earthquake automatic diagnostic driving | operation, this provisional driving | operation includes a temporary restoration driving | operation.
