The floor reservation lights 9A to 9N of the floors 5A to 5N are connected to the unit control apparatus 4A, the landing reservation lights 10A to 10N of the floors 5A to 5N are connected to the unit control apparatus 4B, and the unit control apparatus 4C The floor reservation lights 11A to 11N on the floors 5A to 5N are connected.

  Next, with reference to FIG. 2, the structure of elevator machine 2A, 2B, 2C is demonstrated. FIG. 2 is a schematic configuration diagram showing a configuration of the elevator 2A. Below, although elevator 2A is demonstrated, since elevators 2B and 2C are the structures similar to elevator 2A, description is abbreviate | omitted.

  As shown in FIG. 2, in addition to the destination floor registration device 7A and the liquid crystal display 8A, a security camera 12 and the like are arranged in the car. The security camera 12 is installed at a position facing the door in the car, and photographs the inside of the car including the liquid crystal display 8A from the position. The image data 13 photographed by the security camera 12 is taken into the number control device 4A.

  The machine control device 4A includes a video analysis device 14 that detects an abnormal display of the liquid crystal display 8A using the image data 13 from the security camera 12. The configuration of the machine control device 4A will be described in detail later.

  A car control device 15 is provided at the upper part of the car. An input signal 16 from the destination floor registration device 7A is transmitted to the car controller 4A via the car controller 15, and an output signal 17 from the car controller 4A is sent to the liquid crystal display via the car controller 15. Sent to 8A.

  FIG. 3 shows the liquid crystal display 8A in a steady state. FIG. 3 is a front view of the liquid crystal display 8A.

  As shown in FIG. 3, on the liquid crystal display 8A, car position character information 19 indicating the current floor and moving direction information 20 indicating the moving direction of the car by an arrow or the like are displayed on the background screen 18. Yes. In addition to the car position character information 19 and the movement direction information 20, information indicating the next floor to stop and information indicating weather and date / time may be displayed.

  FIG. 4 is a block configuration diagram showing a schematic configuration of the video analysis device 14. As shown in FIG. 4, the video analysis device 14 in the machine control device 4A includes a receiving unit 21, a crime prevention data storage unit 22, a timing determination unit 23, a display information extraction unit 25, a match determination unit 26, and a display power supply restart. A unit 27, a storage unit 28, a control unit 29, and the like.

  Image data from the security camera 12 is captured by the receiving unit 21. The security data storage unit 22 acquires the image data 13 obtained by photographing the inside of the car taken in by the receiving unit 21, and provides it to a function unit (not shown) that executes various security processes. The security data storage unit 22 provides the image data 13 to the timing determination unit 23, the display information extraction unit 25, and the like.

  The timing determination unit 23 detects the stop timing of the car and determines the start timing of the abnormal display detection process. When the car is moving, the display content displayed on the liquid crystal display 8A changes. Therefore, it is necessary to execute an abnormal display detection process when the car is stopped. Therefore, the timing determination unit 23 uses the stop timing of the car as the start timing of the display detection process. In addition, in order to avoid executing the abnormal display detection process many times unnecessarily when the car is stopped, the timing determination unit 23 detects the abnormal display when the car shifts from the running state to the stopped state. Execute the process.

  The display information extraction unit 25 acquires the image data 13 obtained by photographing the inside of the car by the security camera 12 when the stop state of the car is detected by the timing determination unit 23, and the liquid crystal display is obtained from the image data 13. The part corresponding to 8A is extracted and the display information is analyzed.

  The match determination unit 26 compares the display information extracted by the display information extraction unit 25 with the correspondence information managed by the number control device 4A to determine whether they match. The display power supply restarting unit 27 performs a detection process started by receiving a signal from the timing determining unit 23 when the match determining unit 26 determines that the display information matches the managed correspondence information. When the match determination unit 26 determines that the display information does not match the managed correspondence information, the liquid crystal display 8A is restarted.

  The match determination unit 26 uses, for example, information on the car position display floor as information for determining whether or not they match, but is not limited to this example. For example, the information may be determined by combining a car position display floor and an arrow (moving direction information) indicating the moving direction of the car. In addition, the information shown in FIG. 3 may be combined with the information indicating the next floor to stop, the information indicating the weather or the date, and the like.

  The storage unit 28 is a storage device that stores a series of processing programs related to the display of the liquid crystal display 8A. The storage unit 28 is a ROM (Read Only Memory) that stores programs used by the CPU 101, calculation parameters, and the like, and is used in the execution of the CPU 101. And a RAM (Random Access Memory) that temporarily stores parameters that change as appropriate during execution of the program.

  The control unit 29 functions as an arithmetic processing device and a control device, and controls the overall operation in the video analysis device 14 according to various programs.

  Next, the details of the abnormality detection process in the video analysis device 14 will be described with reference to FIG. FIG. 5 is a flowchart showing details of the abnormality detection process.

  As illustrated in FIG. 5, when the timing determination unit 23 detects that the abnormal display detection start timing is reached, the timing determination unit 23 determines whether the car is stopped (S101). If it is determined in step S101 that the car is stopped, the timing determination unit 23 determines whether the car is traveling from the start timing of the previous abnormal display detection (S102).

  The timing determination unit 23 acquires the state information of the car indicating whether the car is running or stopped from the control unit 29 periodically (for example, every 5 seconds). For example, the acquired state information of the car is information indicating “travel”, “travel”, “travel”, “stop”, “stop”, and “travel” every 5 seconds.

  When it is determined in step S101 that the car is stopped, it is determined whether or not the state information of the car just before it is determined to be “stop” in step S102 is “running”. In other words, as described above, when the state information of the car is “running”, “running”, “running”, “stop”, “stop”, “running”, the car state information is “stop”. "Is" running "immediately before the determination is made, step S103 is executed, and if it is" stop ", the abnormal display detection process is terminated.

  By the processing of step S101 and step S102, the abnormal display detection process can be executed while the car is stopped, and further, the abnormal display detection process is prevented from being repeatedly executed unnecessarily while the car is stopped. can do.

  If it is determined in step S102 that the previous state information of the car is not “running”, the process of step S103 is performed. If it is determined that the car is not running, the process is terminated.

  In step S103, the display information extraction unit 25 acquires the image data 13 obtained by photographing the inside of the car by the security camera 12, extracts a portion corresponding to the liquid crystal display 8A from the image data 13, and analyzes the display information. To do. If the display shown in FIG. 3 is displayed on the liquid crystal display 8A, the display information extraction unit 25 analyzes the display information and acquires “3” of the car position display floor.

  Subsequently, the match determination unit 26 displays the display information extracted by the display information extraction unit 25 in step S103, that is, the car position display floor “3”, and the correspondence information managed by the machine control device 4A, that is, the car position stop floor. Information is acquired and it is determined whether or not the two match (S104).

  In step S104, it is assumed that the match determination unit 26 determines that the display information does not match the car position stop floor information. In this case, the display power supply restarting unit 27 turns off the power of the liquid crystal display 8A, and then turns on to restart the power of the liquid crystal display 8A (S105). By restarting the power supply of the liquid crystal display 8A, the liquid crystal display 8A can be restored relatively easily.

  In step S104, when the match determination unit 26 matches the display information and the car position stop floor information, the current process started upon receiving a signal from the timing determination unit 23 is terminated.

  Note that even if the power supply of the liquid crystal display 8A is restarted in step S105 and the liquid crystal display 8A is restored, the malfunction of the liquid crystal display 8A may be detected again. If a failure is detected a plurality of times even after restarting, a failure has occurred in the liquid crystal display 8A itself or a series of processing programs related to the display of the liquid crystal display 8A. May not be resolved. For example, if the liquid crystal display 8A is restarted a predetermined number of times or more while the car is operating, an error notification such as displaying an error without restarting may be made.

  As described above, when the information on the car position display floor is used as the display information on the liquid crystal display 8A, it is possible to improve the extraction accuracy and the determination accuracy from the image data. Further, by using the information on the car position display floor, it is possible to easily perform a match determination with the corresponding car position stop floor information managed by the number control device 4A.

  Furthermore, the timing at which the match determination unit 26 performs the determination is performed when the timing determination unit 23 determines that the car is stopped. For this reason, since the display information of the liquid crystal display 8A in the image data 13 captured from the security camera 12 is still image information, the determination accuracy can be further improved.

  In this way, when the liquid crystal display 8A that performs multi-function display is used, even if the software configuration is complicated and the liquid crystal display 8A does not operate correctly and does not display correctly, it is already in the car. It is possible to easily confirm that the liquid crystal display 8A is displaying normally from the outside by efficiently utilizing the security camera 12 installed in. Furthermore, since the security camera 12 is used, it is possible to accurately check the actual display with a simple configuration.

  In addition, although elevator 2A was demonstrated above, the structure in the cage | basket | car of elevator 2B and 2C is also the same. The present invention is not limited to the above-described embodiment, and includes various modifications.
