The communication device 28 is a computer including a CPU for performing information processing and a memory for storing an operation program or data in addition to a communication function. The communication device 28 analyzes the contents of received mail and extracts data or receives received mail. Can generate a mail reception signal.

  The elevator management information center 50 is a facility for remotely monitoring whether or not an abnormality has occurred in the elevator 20, and the information processing device 52, which is a server, includes an installation point, a model number, a serial number, a failure history, and an operation of the elevator 20. The occurrence of an abnormality in the elevator 20 is monitored based on various data such as history and maintenance history. For remote monitoring of the elevator 20, for example, the control device 27 outputs operation data of the elevator 20 to the communication device 28 according to a predetermined schedule, and the communication device 28 transmits this operation data to the elevator management information center 50. The information processing device 52 of the elevator management information center 50 analyzes the operation data of the elevator 20 input via the communication device 51 and monitors the state of the elevator 20.

  The meteorological information providing service center 40 stores weather information including torrential rain information at various locations in an information processing device 42 as a server. In addition, the information processing apparatus 42 has a database, in which a customer registration location, an email address, and the like are stored. The weather information providing service center 40 may generate a heavy rain in the vicinity of the customer's registered place within a short period of time within 10 to 30 minutes, for example, based on the concentrated heavy rain information stored in the database. In such a case, a concentrated heavy rain occurrence prediction mail as shown in FIG. 2 is transmitted to the registered customer mail address.

  Next, the operation of the elevator system 100 will be described with reference to FIG. In the following description, the installation location of the elevator 20, which is also the installation location of the communication device 28, is registered in the registration location of the database of the weather information providing service center 40, and the e-mail address includes the unique e-mail address of the communication device 28 Will be described as being registered. Further, in the following explanation, the flooding operation of the elevator 20 does not stop the elevator 20 on the underground floor and the ground floor where flooding is expected, but floods the evacuation that operates the elevator 20 so as to stop only on the second floor or higher. The operation and the operation of the inundation prevention device that closes the waterproof shutter 15 on the basement floor and the ground floor will be described.

  The information processing device 42 of the weather information providing service center 40 may cause a torrential rain within 10 to 30 minutes around the installation point of the elevator 20 as a registration site based on the torrential rain information stored in the database. If it is determined that there is, a concentrated heavy rain occurrence prediction mail as shown in FIG. 2 is transmitted to the unique mail address of the communication device 28 which is a registered mail address. As shown in FIG. 2, the concentrated heavy rain occurrence prediction mail includes “concentrated heavy rain occurrence prediction mail” as the subject, communication date and time, and the address of the installation point of the elevator 20 as the registration location. In the text, there is a fixed sentence “There is a possibility of heavy rain and thunderstorms in the vicinity of the registered site” and the expected start time of rain, which is the expected start time of rain. Also, at the end of the sentence, the name of the sender is described as “weather information providing service center”.

  As shown in step S <b> 101 of FIG. 3, the communication device 28 waits until a torrential rain occurrence prediction mail is received from the weather information providing service center 40. Whether or not a heavy rain forecast e-mail has been received may be determined by the address of the sender of the e-mail, or by determining that the name of the sender is included in the e-mail text. You may make it do.

  When the communication device 28 receives the concentrated heavy rain occurrence prediction mail from the weather information providing service center 40, the communication device 28 determines YES in step S101 of FIG. 3, and proceeds to step S102 of FIG.

  In step S102 in FIG. 3, the communication device 28 extracts the predicted rainfall start time from the text data in the sentence of the torrential rain occurrence prediction mail shown in FIG. 2, and proceeds to step S103 in FIG. Generate a mail reception signal to be output. Then, the process proceeds to step S104 in FIG. 3 to output a mail reception signal and expected rainfall start time data to the control device 27.

  When the mail reception signal and the expected rainfall start time data are input from the communication device 28, the control device 27 calculates the inundation-compatible operation start time in step S105 of FIG. When the flooding operation is the flooding evacuation operation and the operation of the flooding prevention device, the control device 27 calculates the start time of the flooding evacuation operation and the flooding prevention device operation start time. For example, the control device 27 closes the waterproof shutter 15 on the basement floor and the ground floor, which are inundation prevention devices, 20 minutes before the expected rain start time, and 5 minutes after that. Each start time is calculated as follows. And the control apparatus 27 waits until it becomes the time. Thus, the control device 27 adjusts the timing at which the flooding operation of the elevator 20 is performed in accordance with the expected rainfall start time.

  When the start time of the flooding operation is reached, the control device 27 proceeds to step S106 in FIG. 3 and starts the flooding operation. According to the previous example, the control device 27 first starts the flooding evacuation operation of the elevator 20 and sets the stop floor so that the elevator 20 does not stop on the basement floor and the ground floor but stops only on the second floor or higher. Restrict. Then, when the flooding operation is performed for 5 minutes, the waterproof shutter 15 on the basement floor and the ground floor is started to close. It takes about 1-2 minutes to close the waterproof shutter 15. As a result, the transition to the flooding operation is completed 10 minutes before the expected rainfall start time.

  Thereafter, when the heavy rain starts, the inundation-compatible operation state is maintained, and the process waits until the inundation-response operation is canceled as shown in step S107 of FIG.

  There are various methods for canceling the flooding operation. For example, the manager of the elevator 20 may cancel the flooding operation by confirming the end of the rain and pressing the release button of the control device 27.

  When the flooding operation is canceled, the control device 27 proceeds to step S108 in FIG. 3 to open the waterproof shutter 15, and then stops the flooding operation and stops the car 22 on all floors. return.

  As described above, the elevator system 100 according to the present embodiment performs the flooding operation on the elevator 20 when the communication device 28 installed at the same point as the installation point of the elevator 20 receives the concentrated heavy rain occurrence prediction mail. Therefore, the elevator 20 can be shifted to the flooded operation state before the heavy rain occurs. Thereby, the flooding to the elevator 20 at the time of heavy rain can be suppressed effectively. In addition, it is possible to suppress the occurrence of passenger confinement due to the occurrence of heavy rain.

  Further, in the elevator system 100 according to the present embodiment, the elevator 20 is caused to start the flooding operation by the concentrated heavy rain occurrence prediction mail transmitted from the weather information providing service center 40 regardless of the command from the elevator management information center 50 or the like. I have to. For this reason, there is no delay in command transmission as in the case where commands are transmitted from the elevator management information center 50 by polling, and the flooding operation can be started in a timely manner. Thereby, generation | occurrence | production of the flooding to the elevator 20 at the time of heavy rain and the confinement of a passenger can be suppressed effectively.

  In the above description, the elevator 20 has been described as performing the flooding operation, that is, the flooding operation for limiting the stop of the car 22 to the basement floor and the ground floor and the waterproof shutter 15 being closed. For example, the operation of the elevator 20 may be stopped while the car 22 of the elevator 20 is stopped on the upper floor. Further, only one of the flooding retreat operation and the closing of the waterproof shutter 15 may be performed. Further, when the communication device 28 receives the concentrated heavy rain occurrence prediction mail, the communication device 28 also transmits a mail reception signal to the elevator management information center 50, and the elevator management information center 50 sends the elevator 20 based on the received mail reception signal. It is also possible to transmit a flooding-response operation start command to another elevator 20 installed in the vicinity of the other elevator 20 to cause the other elevator 20 installed in the vicinity to start a flooding-response operation.

  In the above description, the communication device 28 has been described as being connected to one control device 27 of one elevator 20. However, the present invention is not limited to this. For example, one communication device 28 in which a plurality of elevators 20 are installed. One communication device 28 is provided in the building, and one communication device 28 and each control device 27 of each elevator 20 are connected to each other. You may comprise so that the data of an estimated start time may be output.

  In addition, for example, in the case where a predicted heavy rain occurrence forecast mail is sent 10 minutes before the predicted heavy rain occurrence predicted time, the predicted rainfall start time is extracted, and the predicted rainfall start time is determined according to the expected rainfall start time. If the concentrated heavy rain occurrence prediction mail is received without adjusting the timing at which the flooding operation of the elevator 20 is performed, the flooding operation may be started immediately.

  Next, another elevator system 200 will be described with reference to FIG. The same parts as those of the elevator system 100 described above with reference to FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof is omitted.

The same as the elevator 20, the control device 27, and the communication device 28. However, the first communication device 28 and the second communication device 128 can communicate with each other via the communication network 35. The second elevator 120 is installed in the vicinity of the first elevator 20.

  Next, the operation of the elevator system 200 will be described with reference to FIG. In the following description, the second elevator 120 is installed in the vicinity of the first elevator 20, but when the first communication device 28 of the first elevator 20 receives the concentrated heavy rain occurrence prediction mail, the concentrated heavy rain still occurs. The operation when the predicted mail is not received will be described.

  As shown in step S201 of FIG. 5, the first communication device 28 is on standby until it receives a torrential rain occurrence prediction mail. Then, when the first communication device 28 receives the concentrated heavy rain occurrence prediction mail, the first communication device 28 proceeds to step S202 in FIG. 5 and outputs a mail reception signal to the first control device 27 and receives the mail to the second communication device 128. Send a signal. When the second communication device 128 receives a mail reception signal from the first communication device 28 as shown in step S203 of FIG. 3, the second communication device 128 sends a mail reception signal to the second control device 127 as shown in step S204 of FIG. Is output.

  As shown in step S205 of FIG. 5, when the mail reception signal from the second communication device 128 is input, the second control device 127 outputs a forecast for starting the flooding operation. The forecast output is, for example, “Torrential rain is approaching. The basement and the first floor will soon stop.” Or “Torrential rain is approaching. "Passengers should get off the elevator promptly" or the like is displayed on the display in the car 122, or voice is played through the speaker in the car 122.
