Description

  The present invention relates to an elevator control device and a control method for notifying an elevator maintenance worker that an emergency earthquake warning has been received.

  In recent years, based on information from seismometers (earthquake detectors) installed throughout Japan, emergency earthquake alerts are delivered to various locations using the Internet and satellite communications immediately after the earthquake occurs, thereby reaching the main movement of the earthquake. Efforts and proposals have been made to take effective measures against the earthquake. Since the above earthquake early warning is delivered immediately after the occurrence of the earthquake, it cannot be used effectively in the event of a direct earthquake, but it will take some time for the main motion to arrive after receiving the emergency earthquake early warning. When it is applied, that is, when a relatively large earthquake occurs in a remote place, it is possible to prevent an earthquake disaster by effectively using the received emergency earthquake bulletin.

  As a conventional elevator technology that uses such an earthquake early warning, the arrival time of the seismic wave (major motion) at the current location from the received earthquake early warning when the earthquake early warning including the epicenter of the earthquake and the time of occurrence of the earthquake is received. And controlling an elevator earthquake control operation based on this prediction has been proposed (see, for example, Patent Document 1).

JP 2004-224469 A

With the thing of patent document 1, if effective control operation at the time of an earthquake based on the received emergency earthquake bulletin can be implemented, it will become possible to prevent an earthquake disaster beforehand. However, for example, when an elevator maintenance worker conducts periodic inspections, maintenance inspections, etc., that is, when the elevator is under maintenance, the alarm prevention function in the control panel is activated. Even if the earthquake early warning is received, there is a problem that there is no means for notifying the maintenance staff that the earthquake early warning has been received. In such a state, the control operation during the earthquake is also disabled, and no rescue operation is performed.
In addition, it is conceivable to receive earthquake early warnings using mobile phones owned by maintenance personnel, but it is difficult for radio waves to reach within the hoistway, and maintenance personnel are working on the cage etc. , There was a fear that the earthquake early warning could not be received.

  The present invention has been made in order to solve the above-described problems. The purpose of the present invention is to provide an earthquake early warning to an elevator maintenance worker who performs maintenance and inspection when the elevator is under maintenance. It is an object to provide an elevator control device and an elevator control method capable of reliably notifying that the vehicle has been received.

And a notification means for notifying the elevator maintenance staff that the emergency earthquake warning has been received when the determination means determines that the elevator is under maintenance when the emergency earthquake warning is received. And.

  The elevator control method according to the present invention includes a step of receiving an emergency earthquake bulletin delivered from the outside by an receiving unit after an earthquake occurs, and an elevator is being maintained by a determining unit when the earthquake early warning is received by the receiving unit. If the elevator determines that the elevator is under maintenance when the determination means receives the earthquake early warning, the notification means sends an emergency earthquake warning to the elevator maintenance staff. And a step of notifying that it has been received.

  According to the present invention, when the elevator is under maintenance, it is possible to reliably notify the elevator maintenance personnel who are carrying out maintenance inspections and the like that the earthquake early warning has been received.

The emergency earthquake bulletin distribution center 9 transmits the emergency earthquake bulletin distributed immediately after the occurrence of the earthquake to the elevator control panel 8 based on information from seismometers installed throughout Japan.

  Further, the control panel 8 is provided with maintenance tool detection means 11, inspection switch detection means 12, manual speed mode detection means 13, information input means 14, determination means 15, and information output means 16. Here, the maintenance tool detection means 11 determines whether or not a maintenance tool 17 (PC or the like) used when an elevator maintenance worker performs periodic inspection or maintenance inspection of the elevator is connected to the elevator (control panel 8). That is, it is a means for detecting whether or not the maintenance tool 17 is communicable with the elevator (control panel 8). Then, the maintenance tool detection means 11 indicates that when the maintenance tool 17 is connected to the elevator, maintenance personnel are carrying out regular inspections and maintenance inspections of the elevator, that is, maintenance that the elevator is under maintenance. Information is output to the determination means 15.

  The maintenance switch detection means 12 includes a maintenance switch (not shown) in the control panel 8 that is in an operating state (ON state) when an elevator maintenance worker performs periodic inspection and maintenance inspection of the elevator. It is a means for detecting whether or not the operation state. The maintenance switch detection unit 12 outputs maintenance information to the determination unit 15 when the maintenance switch in the control panel 8 is in an operating state. The maintenance switch is provided with a notification blocking function that prevents notification to the inside and outside of the elevator when in an operating state. When the maintenance switch is in an operating state, for example, a safety device or the like Even if an elevator abnormality is detected, the alarm is prevented. The manual speed mode detection means 13 is a means for detecting whether or not the current elevator operation mode is an operation mode when the maintenance staff carries out regular inspections and maintenance inspections of the elevator, that is, the manual speed mode. is there. The manual speed mode detection means 13 outputs maintenance information to the determination means 15 when the current elevator operation mode is the manual speed mode.

  The information input means 14 is a means for taking in various information from the outside into the control panel 8, and functions as a receiving means for receiving the emergency earthquake bulletin distributed from the external emergency earthquake bulletin distribution center 9 after the occurrence of an earthquake. Have

  When the control panel 8 receives the earthquake early warning via the information input unit 14, the determination unit 15 performs regular inspections and maintenance inspections of the elevator by the maintenance personnel, that is, the elevator is under maintenance. It is means for determining whether or not. Specifically, the determination unit 15 determines that the elevator is under maintenance when maintenance information is input from any one of the maintenance tool detection unit 11, the inspection switch detection unit 12, and the manual speed mode detection unit 13. judge. When the control panel 8 receives the earthquake early warning during the maintenance of the elevator, the determination means 15 makes an emergency call to the elevator maintenance staff regardless of the activation state of the alarm blocking function of the control panel 8. A notification command for notifying that the earthquake early warning has been received is output.

  The information output unit 16 is a unit for outputting various types of information to the outside of the control panel 8 and outputs a notification command output from the determination unit 15 to the notification unit. In addition, when the determination means 15 determines that the elevator is under maintenance when the emergency earthquake warning is received, the notification means notifies the elevator maintenance staff that the emergency earthquake warning has been received. For example, it is constituted by a maintenance tool 17 connected to the elevator only during maintenance, a notification device 18 provided in the elevator at all times, and the like. Here, on the maintenance tool 17, based on the notification command output from the determination unit 15, for example, the fact that the emergency earthquake warning has been received is displayed on the display screen in characters or the like. The notification device 18 includes a speaker 19 provided in a place where maintenance personnel may enter such as the machine room 6 and the pit portion of the hoistway 2, a car buzzer 20, an in-car display and a landing display (both (Not shown) or the like, and notifies that the earthquake early warning has been received by voice guidance or text display. Even when the maintenance switch having a notification preventing function is provided in the control panel 8, the notification means is based on the notification command output from the determination means 15 regardless of the operating state of the maintenance switch. To notify that the earthquake early warning has been received.

  Next, the operation of the elevator control apparatus having the above configuration will be described in detail with reference to FIG. In the following, a case will be described in which an earthquake early warning is delivered before the main motion of the earthquake arrives due to a relatively large earthquake occurring in a remote place.

  When an emergency earthquake bulletin is delivered from the emergency earthquake bulletin distribution center 9 due to the occurrence of an earthquake (step S101), the elevator receives the emergency earthquake bulletin by the receiving means including the information input means 14 in the control panel 8. (Step S102). When the earthquake early warning is received by the receiving means, the determining means 15 in the control panel 8 determines whether or not the elevator is under maintenance. When the determining means 15 determines that the elevator is under maintenance when the emergency earthquake warning is received, the notifying means notifies the elevator maintenance staff that the emergency earthquake warning has been received.

  Specifically, when the earthquake early warning is received by the receiving means, first, whether or not the maintenance information is input from the maintenance tool detecting means 11 by the judging means 15, that is, the maintenance tool 17 of the elevator maintenance staff It is determined whether it is connected to the elevator (control panel 8) (step S103). Here, if maintenance information is input from the maintenance tool detection means 11, it is determined that the elevator is under maintenance, and the fact that the earthquake early warning has been received is displayed on the display screen of the maintenance tool 17 (step). S104).

  On the other hand, if it is determined in step S103 that maintenance information has not been input from the maintenance tool detection means 11, or if the fact that an emergency earthquake warning has been received is displayed on the display screen of the maintenance tool 17 in step S104. Then, the determining means 15 determines whether or not maintenance information is input from the checking switch detection means 12, that is, whether or not the checking switch in the control panel 8 is in an operating state (step S105). Here, when maintenance information is input from the switch detection means 12 during inspection, it is determined that the elevator is under maintenance, the car buzzer 20 is sounded, and an emergency earthquake warning is received from each speaker 19. An announcement has been made (step S106). And by each operation | movement of step S104, 106, an elevator maintenance worker recognizes that the shaking of an earthquake generate | occur | produces within a short time, and implements the predetermined | prescribed operation | movement for ensuring own safety (step S107). .

  If it is determined in step S105 that maintenance information has not been input from the checking switch detection unit 12, the determination unit 15 determines whether maintenance information has been input from the manual speed mode detection unit 13, that is, Then, it is determined whether or not the current operation mode is the manual speed mode (step S108). When maintenance information is input from the manual speed mode detection means 13, it is determined that the elevator is under maintenance, and the operation of step S106 is performed to avoid the danger of maintenance personnel. On the other hand, if it is determined in step S108 that maintenance information has not been input from the manual speed mode detection means 13, it is determined that the elevator is not being inspected, and the maintenance staff is notified that an emergency earthquake warning has been received. The predetermined operation is not performed (step S109), and the operation ends.

  According to the first embodiment of the present invention, when the elevator is under maintenance, it is possible to reliably notify the elevator maintenance personnel who are carrying out the maintenance inspection and the like that the earthquake early warning has been received. . For this reason, the elevator maintenance personnel who have received the above notification can be prepared to shake the earthquake in a short period of time and perform various actions to ensure safety before the main movement of the earthquake arrives. It becomes possible to do. For example, a maintenance worker riding on the car 1 can perform operations such as grasping a handrail so as not to fall from the car 1 or squatting on the central part of the car 1 to protect the head from falling objects. In addition, the maintenance staff in the pit portion of the hoistway 2 can perform operations such as moving to a position where there is no fear of falling objects or escaping from the pit portion when the doorway is close.

  In the first embodiment, when maintenance information is input from the maintenance tool detection unit 11, it is displayed on the maintenance tool 17, and when maintenance information is input from the inspection switch detection unit 12, a speaker is displayed. The operation of a predetermined notification means is performed according to the output source of the maintenance information, such as the announcement from 19 and the ringing of the buzzer 20 on the car. However, because the location and operation of the maintenance personnel who are performing maintenance and inspection of the elevator cannot be specified, if an earthquake early warning is received during maintenance of the elevator, it will be notified regardless of the output source of the maintenance information. All possible operations of the means may be performed at the same time so as to reliably notify the maintenance staff that the earthquake early warning has been received.
