The control part 14 is included.

  The elevator transmission / reception unit 11 transmits / receives various data and signals to / from the elevator control device 4. The monitoring center transmission / reception unit 12 transmits / receives various data and signals to / from the monitoring center 3.

  The storage unit 13 is, for example, a ROM (Read Only Memory) that stores a program executed by the control unit 14, an HDD (Hard Disk Drive) that fixedly stores information transmitted to and received from the elevator control device 9 and the monitoring center 3. ), And hardware including a RAM (Random Access Memory) serving as a work area when the control unit 14 executes the program.

  The control unit 14 functions as, for example, a microcomputer that executes a program stored in the storage unit 13 and performs various calculations. And the control part 14 is monitoring the state of the elevator 1 via the transmission / reception part 11 for elevators, and the elevator control apparatus 9, and when it detects that the state of the elevator 1 is abnormal, it is An abnormal signal of the elevator 1 is transmitted to the monitoring center 3 via the transmission / reception 12. In addition, the control unit 14 includes a fan operation state notification unit 14 </ b> A that notifies the monitoring center 3 of the operation state of the fan 7.

  The fan operation state notifying unit 14 </ b> A determines the operation state of the fan 7 based on the operation signal of the fan switch 8 input by the elevator transmission / reception unit 11. Then, the fan operation state notification unit 14 </ b> A transmits an operation state signal of the fan 7 to the monitoring center 3 via the counter-monitoring center transmission / reception unit 12 when it is determined that the operation state of the fan 7 is the operation state.

Therefore, when the fan switch 8 is operated to the ON state or the OFF state, the operation signal of the fan 7 is transmitted after the operation signal for the ON state or the OFF state of the fan switch 8 is transmitted from the elevator control device 9 to the monitoring terminal 2. Then, an operation state signal indicating either the stop state signal or the stop state signal is transmitted from the monitoring terminal 2 to the monitoring center 3.

  The monitoring center 3 receives various types of information such as the number of operations of the fan 7 for each of the areas A to C, which will be described later, and the transmission / reception unit 16 for the monitoring terminal that is connected to the external monitoring terminal 2 via the public line network 4. Storage unit 17 for storing, property database for registering property information of each elevator 1 belonging to regions A to C (in FIG. 1, the database is abbreviated as DB for convenience) 18A to 18C, and for these monitoring terminals The transmission / reception unit 16, the storage unit 17, the control unit 19 that controls the operation of the property databases 18 </ b> A to 18 </ b> C, and the property information of each elevator 1 belonging to the areas A to C, and the input / output that outputs various types of information by video Part 20.

  The monitoring terminal transmission / reception unit 16 transmits and receives various data and signals to and from the monitoring terminal 2. The storage unit 17 is, for example, a ROM that stores a program executed by the control unit 19, information that is transmitted to and received from the monitoring terminal 2, and information that is input by the input / output unit 20, similar to the storage unit 13 of the monitoring terminal 2. Are fixedly stored, and hardware including a storage device such as a RAM serving as a work area when the control unit 19 executes a program. In addition, the storage unit 17 stores information on an operation flag indicating whether the fan 7 is remotely operated by the monitoring center 3 and a stop flag indicating whether the fan 7 is remotely stopped by the monitoring center 3. .

  Each of the property databases 18A to 18C is configured by a storage device such as an HDD that stores information in a fixed manner. The property database 18A is an identification number that identifies each elevator 1 belonging to the area A as property information, for example. , The address of the building where each elevator 1 belonging to area A is installed, and information such as the number of fans 7 installed in each elevator 1 belonging to area A are stored.

As a specific example, the first threshold value and the second threshold value are each set to a value of 3% for the elevator 7 of the elevator 1 included in all the property information registered in the property databases 18A to 18C. Each can be set as a fixed value.

  Therefore, in the areas A to C, for example, as shown in FIG. 2, when the number of operations of the fan 7 in the area B reaches a predetermined first threshold (three in the example shown in FIG. 2), the control command Since the operation control command is transmitted from the monitoring center 3 to the elevator control device 9 of each elevator 1 in the region B by the transmission unit 19C, all the elevators 1 belonging to the region B are transmitted by these elevator control devices 9. The fans 7 operate simultaneously.

  The input / output unit 20 includes, for example, a personal computer including an operation device such as a mouse and a keyboard operated by a user in the monitoring center 3 and a display device such as a liquid crystal display for displaying an image.

At this time, if the area determination unit 19B determines that the number of operations of the fans 7 of the elevator 1 belonging to the area has not reached the predetermined first threshold value (S306 / NO), the control process from S301 is performed.

  On the other hand, if the area determination unit 19B determines in S306 that the number of operations of the fans 7 of the elevator 1 belonging to the area has reached the predetermined first threshold (S306 / YES), the control command transmission unit of the control unit 19 19C transmits the operation control command with respect to the said area to the monitoring terminal 2 via the transmission / reception part 16 for monitoring terminals (S307).

  Then, the control unit 19 turns on the operation flag corresponding to the area (S308), and among the stop counters (not shown) set for each of the areas A to C inside, the area specified in S302 Is set to 0 (S309), and the control processing from S301 is repeated.

  In S303, when the control unit 19 determines that the operation state signal of the fan 7 is not an operation state signal, that is, a stop state signal (S303 / NO), the control unit 19 refers to the information stored in the storage unit 17 to refer to S302. Whether or not the stop flag corresponding to the area identified in step 1 is ON, that is, the fans 7 of the elevators 1 belonging to the area have already been stopped all at once by the remote control of the operation of the fan 7 by the monitoring center 3. (S310). At this time, if the control unit 19 determines that the stop flag corresponding to the area is in the ON state (S310 / YES), the control process from S301 is performed.

  In S310, when the control unit 19 determines that the stop flag corresponding to the area is not in the ON state, that is, in the OFF state (S310 / NO), the calculation unit 19A of the control unit 19 internally Of the stop counters (not shown) set for each of the areas A to C, the stop counter corresponding to the area specified in S302 is incremented to calculate the number of stops of the fans 7 of the elevator 1 belonging to the area. (S311).

  Next, the area determination unit 19B of the control unit 19 determines whether the number of stops of the fans 7 of the elevator 1 belonging to the area calculated by the calculation unit 19A has reached a predetermined second threshold (S312). At this time, if the area determination unit 19B determines that the number of stops of the fans 7 of the elevator 1 belonging to the area has not reached the predetermined second threshold (S312 / NO), the control process from S301 is performed.

At this time, when the control unit 14 confirms that the operation signal of the fan switch 8 has been received (S401 / YES), the fan operation state notification unit 14A of the control unit 14 receives the fan 7 from the received operation signal of the fan switch 8. It is determined whether the operating state is an operating state (S402).

  In S402, when the operation signal of the fan switch 8 is an ON operation signal, the fan operation state notifying unit 14A determines that the operation state of the fan 7 is in the operating state (S402 / YES). An operation state signal of the fan 7 is transmitted to the monitoring center 3 via the transmission / reception unit 12 (S403), and control processing from S401 is performed.

  In S402, when the operation signal of the fan switch 8 is an OFF operation signal, the fan operation state notification unit 14A determines that the operation state of the fan 7 is not an operation state, that is, the operation state of the fan 7 is a stop state. Therefore (S402 / NO), the stop state signal of the fan 7 is transmitted to the monitoring center 3 via the counter monitoring center transmission / reception unit 12 (S404), and the control processing from S401 is performed.

  On the other hand, in S401, when the control unit 14 confirms that the operation signal of the fan switch 8 has not been received (S401 / NO), the control unit 14 receives an operation control command from the monitoring center 3 via the monitoring center transmitting / receiving unit 12. It is confirmed whether or not (S405). At this time, when the control unit 14 confirms that the operation control command has been received (S405 / YES), the control unit 14 sends the operation control command to the elevator control of each elevator 1 belonging to the corresponding area via the elevator transmission / reception unit 11. It transmits to the apparatus 9 (S406), and the control processing from S401 is repeated.

By transmitting the operation control command to the elevator control devices 9 of the elevators 1 belonging to the area that has reached the above, the elevator control devices 9 operate the fans 7 of the elevators 1 of the corresponding regions all at once. Therefore, in this area, for example, even if the temperature or humidity in the elevator car 6 of each elevator 1 rises as in summer, before passengers in the elevator car 6 feel uncomfortable with the indoor environment, By automatically ventilating the inside of the car 6 by the fan 7, the environment inside the car 6 can be appropriately adjusted according to the change in the climate in the area.

  In addition, the control command transmission unit 19C sends a stop control command to the elevator control device 9 of each elevator 1 belonging to a region where the number of stops determined by the region determination unit 19B among the regions A to C has reached a predetermined second threshold. By transmitting these, the fans 7 of the elevators 1 in the area are stopped all at once by these elevator control devices 9. Therefore, in the area, for example, even if the temperature or humidity in the elevator car 6 of each elevator 1 decreases at night, for example, the ventilation in the elevator car 6 by the fan 7 is quickly stopped. It can suppress that the inside of the cage | basket | car 6 is cooled too much.

  As described above, the present embodiment captures changes in the environment in the car 6 of each elevator 1 in each of the areas A to C without installing a sensor for detecting temperature, humidity, or the like in the car 6. Since the operation of the fan 7 of the car 6 can be automatically switched, the environment in the car 6 can be kept inexpensive and comfortable. Thereby, the serviceability which was excellent with respect to the passenger of the elevator 1 can be provided.

  In addition, this embodiment mentioned above was described in detail in order to demonstrate this invention easily, and is not necessarily limited to what is provided with all the demonstrated structures.
