That is, the abnormality display of the landing button is changed depending on whether an abnormality in the car is detected without being operated by the passenger and when it is detected by the passenger. In this way, by changing the display for abnormality of the landing button, it is possible to inform the person at the landing of the state of passengers in the car (for example, whether or not the device for notifying abnormality can be operated). If the passenger is not able to operate the device to notify the passenger, the passenger may be suddenly ill).

  Embodiments of an elevator abnormality detection system according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a configuration diagram of an elevator abnormality detection system according to a first embodiment of the present invention. The elevator abnormality detection system includes a landing button 101 provided at an elevator landing, an in-car monitoring camera 102, an in-car speaker 104, an in-car indicator 106, and a landing button control device provided at the elevator car. 100. In this embodiment, the car monitoring camera 102 serves as an abnormality detection device that operates regardless of the passenger's operation. The in-car monitoring camera 102 constantly monitors the inside of the car by photographing the inside of the car.

  The landing button 101 is a button that is provided on the elevator operation panel at the landing and is pressed when a passenger calls the car. Generally, an arrow pointing up and an arrow pointing down are displayed (however, only the arrow indicating the down direction is displayed at the hall on the top floor, and indicates the up direction at the hall on the bottom floor. Only the arrow appears). The landing button 101 may be any type of button. In this embodiment, it is a button of a type that lights up when pressed and can notify the passenger that the car is being called.

  The in-car monitoring camera 102 is connected to the remote monitoring center 110 and photographs the inside of the car. The video inside the car taken by the car monitoring camera 102 is transmitted to the remote monitoring center 110. In the remote monitoring center 110, an elevator maintenance worker monitors the inside of the car by looking at the image of the car monitoring camera 102.

  The in-car speaker 104 is connected to the remote monitoring center 110 and transmits the voice guidance by the maintenance personnel of the remote monitoring center 110 to the passengers in the car.

  The in-car indicator 106 is connected to the remote monitoring center 110 and displays a message to the passengers by the operation of the maintenance personnel of the remote monitoring center 110. A message from the remote monitoring center 110 can be notified to passengers by the in-car indicator 106.

  The landing button control apparatus 100 is installed in an elevator hoistway. For example, the hall button control device 100 is provided in an elevator control panel. The hall button control device 100 may be provided on the elevator operation panel at the hall. The landing button control apparatus 100 is connected to the remote monitoring center 110 and the landing button 101, and causes the landing button 101 to display an abnormality display in accordance with a signal transmitted by a maintenance person of the remote monitoring center 110.

  The display for abnormality of the landing button 101 may be any display as long as the display is different from the normal display. The normal display of the landing button 101 includes, for example, a non-lighting display when the car is not called, a lighted display when a passenger presses to call the car, and an elevator door is closed. Includes a flashing display. In addition, the display color of normal lighting and blinking is a color close to yellow or orange. Therefore, the display for abnormality of the landing button 101 is a blinking display at a different interval from the normal blinking interval, a lighting display in a color different from the normal lighting display color, or a combination thereof. It can be a display. Specifically, for example, a blinking display faster than a blinking when the door is closed, a display that lights in red, or a combination of these displays (a high-speed blinking display in red) can be used.

  FIG. 2 is an example of a flowchart of processing for displaying a display for abnormality on the hall button 101 in this embodiment.

  In S201, the elevator maintenance worker in the remote monitoring center 110 monitors the inside of the car by watching the image of the car monitoring camera 102. If the elevator maintenance staff detects a passenger abnormality via the video from the car monitoring camera 102, the process proceeds to S202.

  In S <b> 202, the elevator maintenance staff transmits a signal to the landing button control device 100 in order to display the abnormality display on the landing button 101.

  In step S <b> 203, when the hall button 101 receives a signal from the remote monitoring center 110, it displays a display for abnormality. As described above, the abnormality display is a display different from the normal state of the hall button 101, for example, a red flashing display.

  In S204, the elevator maintenance staff informs passengers in the car that an abnormality in the car has been detected and notified to the person at the landing. There are two methods of communication: a method of transmitting by voice guidance via the car speaker 104 and a method of displaying a message on the car indicator 106 and transmitting the message. Either or both of these methods are used. be able to.

The car loading capacity measured by the car weighing device 103 is transmitted to the remote monitoring center 110. In the remote monitoring center 110, the elevator maintenance staff can determine whether there are passengers in the car based on the loading capacity of the car.

  The display for abnormality of the landing button 101 may be any display as long as the display is different from the normal display, as in the first embodiment.

  FIG. 4 is an example of a flowchart of processing for displaying a display for abnormality on the hall button 101 in the present embodiment.

  In S401, the elevator maintenance worker of the remote monitoring center 110 determines whether or not the elevator has stopped due to an earthquake or the like based on a signal from the elevator. If it is determined that the elevator has stopped urgently, the process proceeds to S402.

  In S <b> 402, the elevator maintenance staff determines whether there are passengers in the car from the loading capacity of the car transmitted from the car weighing device 103. If it is determined that there are passengers in the car, the process proceeds to S403.

  S403 to S406 are the same processing as S202 to S205 shown in FIG.

  As described above, in the elevator abnormality detection system according to the present embodiment, it is possible to detect an abnormality in the elevator car without depending on the operation of the passenger, and notify the person in the hall of the abnormality in the passenger car. Therefore, for example, even in an abnormal case where the passenger cannot be notified to the outside that the passenger is trapped in the elevator due to a sudden illness or the like, such an abnormality can be detected and notified to the landing. Furthermore, since it is possible to inform the passengers in the car that an abnormality in the car has been detected, it is possible to reduce the passenger's anxiety until the maintenance staff arrives at the rescue. In addition, it is possible to inform the person at the landing that the elevator cannot be boarded.

  In this embodiment, the car monitoring camera (see Embodiment 1) is not used. Therefore, the elevator abnormality detection system according to the present embodiment is also applicable to a car not provided with a car monitoring camera.

  The elevator abnormality detection system according to the first embodiment or the second embodiment may further include an abnormality notification device such as an external interphone or an emergency button that can be operated by a passenger's operation to notify the outside of the abnormality. The abnormality notification device is provided inside the car and is connected to the remote monitoring center. The elevator passenger can notify the remote monitoring center of the abnormality by operating the abnormality notification device. In the present embodiment, a configuration in which the elevator abnormality detection system according to the first embodiment includes an external interphone as an abnormality notification device will be described.

  FIG. 5 is a configuration diagram of an elevator abnormality detection system according to Embodiment 3 of the present invention. 5, the same reference numerals as those in FIG. 1 denote the same or common elements as those in the first embodiment, and description of these elements is omitted. The elevator abnormality detection system according to the present embodiment further includes an external interphone 105 provided in the elevator car. An emergency button 107 may be provided instead of or together with the external interphone 105.

  The external interphone 105 and the emergency button 107 are connected to the remote monitoring center 110 and are devices for notifying the outside of the abnormality. However, unlike the abnormality detection apparatuses (the in-car monitoring camera 102 and the car weighing apparatus 103) of the first and second embodiments, the apparatus can notify the outside of the abnormality by operating by the passenger. By using one or both of the external interphone 105 and the emergency button 107, the elevator passenger can contact maintenance personnel at the remote monitoring center 110 and can report an abnormality. When a maintenance person contacts from the passenger via the external intercom 105 or the emergency button 107, the maintenance staff operates the landing button control device 100 to display an abnormality display on the landing button 101.

  Below, the case where the passenger of an elevator contacts the maintenance worker in the remote monitoring center 110 using the external intercom 105 is demonstrated. When the passenger contacts the maintenance staff using the emergency button 107, “external interphone 105” in the following description may be read as “emergency button 107”.

  The display for abnormality of the landing button 101 when the passenger contacts via the external intercom 105 is a display for abnormality different from the display for abnormality in the first and second embodiments. That is, when an abnormality in the car is detected without being operated by a passenger (when detected by the in-car monitoring camera 102 or the car weighing device 103), or when detected by a passenger's operation (external interphone 105). And the display for abnormality of the hall button 101 is changed. In this way, by changing the display for abnormality of the landing button 101 according to the presence or absence of the passenger's operation, the state of the passenger in the car (for example, whether or not the device that notifies the abnormality can be operated) is landing Can inform people in

  When an abnormality is detected by a passenger's operation (when an abnormality is detected by the external intercom 105), the display for abnormality of the hall button 101 is a case where an abnormality is detected regardless of the passenger's operation (the in-car monitoring camera 102 or Any display may be used as long as the display is different from both the display for abnormality (when abnormality is detected by the car scale device 103) and the normal display of the landing button 101. For example, as described in the first embodiment, if the abnormality display when the abnormality is detected without depending on the passenger's operation is a red flashing display, the abnormality is detected when the abnormality is detected by the passenger's operation. The display can be a blue flashing display.

  FIG. 6 is an example of a flowchart of processing for displaying a display for abnormality on the hall button 101 in the present embodiment.

  In S601, when the passenger contacts the elevator maintenance staff of the remote monitoring center 110 via the external interphone 105, the process proceeds to S602. If there is no notification to the maintenance personnel, the process proceeds to S606.

  In S <b> 602, the elevator maintenance staff transmits a signal to the landing button control apparatus 100 in order to display an abnormality display when an abnormality is detected by the external interphone 105.

  In step S <b> 603, the hall button 101 displays an abnormality display when an abnormality is detected by the external intercom 105 (when an abnormality is detected by a passenger's operation). As described above, the display for abnormality when the abnormality is detected by the external interphone 105 is the display for abnormality when the abnormality is detected by the in-car monitoring camera 102 or the car scale device 103 and when the hall button 101 is normal. The display is different from both of the displays, for example, a blue flashing display.

  Since S604 to S605 are the same processes as S204 to S205 shown in FIG.

  Steps S <b> 606 to S <b> 608 are processing when there is no contact from the passenger to the elevator maintenance staff at the remote monitoring center 110 via the external interphone 105.

  Since S606 is the same process as S201 shown in FIG. 2 of the first embodiment, a description thereof will be omitted.

  In S <b> 607, the elevator maintenance staff transmits a signal to the landing button control device 100 in order to display a display for abnormality when an abnormality is detected by the in-car monitoring camera 102.

  In step S <b> 608, the hall button 101 displays a display for abnormality when an abnormality is detected by the in-car monitoring camera 102 (when abnormality is detected regardless of passenger operation). As described above, the display for abnormality when an abnormality is detected by the in-car monitoring camera 102 is different from both the display for abnormality when the abnormality is detected by the external interphone 105 and the display when the hall button 101 is normal. For example, a red flashing display.

  Following S608, the above-described processing of S604 and S605 is performed.

  As described above, in the elevator abnormality detection system according to the present embodiment, the abnormality display of the landing button 101 is detected when an abnormality in the car is detected without being operated by the passenger and when it is detected by the passenger's operation. By changing the above, it is possible to notify the person in the hall of the state of the passenger in the car (for example, whether or not the operation of the external intercom 105 is possible).

  The abnormality detection system for an elevator according to the present invention may be configured to include both the in-car monitoring camera 102 and the car weighing device 103 as an abnormality detection device. Furthermore, it is good also as a structure provided with the monitoring camera 102 in a car, the car scale device 103, and the external intercom 105. FIG. In these configurations, the process of displaying the display for abnormality on the hall button can be realized by combining the processes described in the first to third embodiments (FIGS. 2, 4, and 6).

  The abnormality display of the landing button 101 may be displayed as a whole of the landing button 101 or a part of the landing button 101 may be displayed. For example, when the abnormal display of the landing button 101 is a red flashing display, the entire landing button 101 may flash red rapidly, and a part of the landing button 101, for example, the traveling direction is displayed. Only the arrow shown may blink red rapidly.
