  FIG. 5 is a functional block diagram showing main functions of the video management apparatus 102 according to the present embodiment.

  As shown in FIG. 5, the video management apparatus 102 includes an operating state detection unit 41, a clock unit 42, a recording unit 43, an abnormality detection unit 44, a caution list generation unit 45, and a communication control unit 46. The operating state detection unit 41 monitors the control signal of the control panel 21 of the elevator 101, and when the car 13 is moving up and down in the hoistway 12, or the car door 135 performs an opening / closing operation. When the elevator 101 is in operation, a state where the elevator 101 is operating (hereinafter referred to as an operating state for convenience) is detected.

  The clock unit 42 acquires the current time and outputs it to the recording unit 43 and the caution list generation unit 45. The recording unit 43 includes a video recording unit 43A. The recording unit 43 acquires a video signal of the camera 131 of the elevator 101, and when the operating state of the elevator 101 is detected by the operating state detection unit 41, a current image displayed by the clock unit 42 is captured by the camera 131. Are recorded in the video recording unit 43A. Thereby, it becomes possible to record all the behaviors of passengers using the elevator 101. Note that the video recording unit 43A is realized by a storage device such as a ROM or an HDD, for example.

  The abnormality detection unit 44 acquires signals of devices provided in the elevator 101, and detects an abnormality associated with an inappropriate predetermined action of a passenger that induces a failure of the elevator 101 based on the signals of these devices. That is, in this embodiment, the abnormality detection unit 44 also functions as a device signal acquisition unit.

That is, the abnormality detection unit 44 is configured such that each of the determination units 441A to 448A independently performs determination according to the type of abnormality. The threshold value recording units 442B to 448B each record in advance threshold values for determining the presence or absence of an abnormality, and each of these threshold values is set in advance for each of the determination units 442A to 448A of the abnormality detection unit 44, for example.

  Hereinafter, details of each of the determination units 441A to 448A of the abnormality detection unit 44 will be described while describing a specific example of a situation that induces a failure of the elevator 101.

  First, the configuration of the abnormal stop determination unit 441A will be described. For example, when the passenger 13 touches the car door 135 while the car 13 is traveling in the hoistway 12 and the door switch 137 is turned off, the car 13 stops and the passenger is in the car 13. There is a possibility that confinement occurs.

  Therefore, in this embodiment, the abnormal stop determination unit 441A monitors the signal of the control panel 21 of the elevator 101, and the door switch 137 is turned on while the car 13 is traveling in a position other than the regular stop floor. When the state is switched to the OFF state, it is determined that an abnormality has occurred in the operation of the elevator 101 and the elevator 13 has stopped moving up and down.

  Next, the configuration of the door abnormality determination unit 442A will be described. For example, when the passenger presses the door safety shoe for a long time without opening the car door 135 without performing a predetermined procedure such as pressing the open button (not shown) in the car 13. Other passengers are inconvenienced and a failure of the elevator 101 is suspected.

  Therefore, in this embodiment, the door abnormality determination unit 442A monitors the signal of the control panel 21 of the elevator 101, and when the opening time of the car door 135 is equal to or greater than the threshold value recorded in the threshold value recording unit 442B. It is determined that an abnormality has occurred in the door 135. Note that the threshold value recorded in the threshold value recording unit 442B may be set to a different value when the passenger presses the open button and when the door safety shoe is pressed.

  Next, the configuration of the motion abnormality determination unit 443A will be described. For example, if a passenger walks around in the car 13 while the car 13 is traveling in the hoistway 12, the elevator 101 may not be able to exhibit predetermined performance due to the balance of the car 13 being lost.

  Therefore, in the present embodiment, the video processing unit 44B calculates the difference in the number of pixels between the video just captured by the camera 131 and the current video. Then, the motion abnormality determination unit 443A determines that an abnormality associated with the movement of the passenger has occurred when the difference in the number of pixels calculated by the video processing unit 44B is equal to or greater than the threshold value recorded in the threshold value recording unit 443B.

  Next, the configuration of the lightness abnormality determination unit 444A will be described. For example, when an ignitable material such as a lighter is used in the car 13, the passenger may be smoking in the car 13, or the push button (not shown) of the car 13 may be burned out. is there.

  Therefore, in the present embodiment, the video processing unit 44B detects a portion where a brightness difference has occurred in the video captured by the camera 131. Then, the brightness abnormality determination unit 444A has an abnormality caused by the brightness (brightness) in the car 13 when the brightness difference detected by the video processing unit 44B is equal to or greater than the threshold recorded in the threshold recording unit 444B. It is determined that it has occurred. Therefore, the video processing unit 44B functions as a brightness difference detection unit.

  Next, the configuration of the torque abnormality determination unit 445A will be described. For example, when a foreign object is caught in the car door 135 due to a passenger dropping an object, the car door 135 is reversed after contacting the foreign object. At this time, since a larger current than usual flows through the door motor 136A, there is a possibility that the elevator 101 may be broken.

  Therefore, in this embodiment, the torque abnormality determination unit 445A determines that an abnormality associated with a foreign object has occurred when the current of the door motor 136A detected by the current sensor 136I is equal to or greater than the threshold value recorded in the threshold value recording unit 445B. To do.

  Next, the configuration of the vibration abnormality determination unit 446A will be described. For example, when the passenger 13 jumps up and down in the car 13 so that the car 13 is vibrated up and down, the car 13 resonates, so that a safety device (not shown) provided in the elevator 101 is provided. There is a possibility of malfunction.

  Therefore, in this embodiment, the vibration abnormality determination unit 446A monitors the output signal of the scale device 132, and when the frequency of the output signal of the scale device 132 becomes equal to or greater than the threshold value recorded in the threshold value recording unit 446B, It is determined that an abnormality accompanying the vibration of the car 13 has occurred.

  Next, the configuration of the noise abnormality determination unit 447A will be described. For example, when a passenger hits a carriage or the like in the car 13 or the car door 135, the car 13 or the car door 135 is damaged, and at the same time, a large noise such as a collision sound is generated.

  Therefore, in the present embodiment, the noise abnormality determination unit 447A determines that an abnormality due to noise has occurred when the volume input by the microphone 133 is equal to or higher than the threshold value recorded in the threshold value recording unit 447B.

  Next, the configuration of the odor abnormality determination unit 448A will be described. For example, when a passenger transports odorous trash or the like into the car 13, the odor remains in the car 13, which may cause discomfort to other passengers who have entered the car 13. .

  Therefore, in the present embodiment, the odor abnormality determining unit 448A determines that the odor abnormality determination unit 448A has the odor abnormality in the car 13 when the odor level in the car 13 measured by the odor sensor 134 is equal to or greater than the threshold value recorded in the threshold value recording unit 448B. It is determined that an abnormality associated with odor has occurred.

  In FIG. 5, the caution list generation unit 45 determines that an abnormality has occurred by at least one of the determination units 441A to 448A of the abnormality detection unit 44 for each of the determination units 441A to 448A of the abnormality detection unit 44. Corresponding watch list (see FIG. 7) in which a detection code as type information set in advance is associated with an abnormality detection time acquired from the clock unit 42 (hereinafter referred to as an abnormality detection time for convenience). Generate. The caution list generation unit 45 includes a caution list recording unit 45A, and records the generated caution list in the caution list recording unit 45A. That is, the caution list recording unit 45A functions as an abnormality detection time recording unit.

  FIG. 7 is a diagram showing an example of a caution list recorded in the caution list recording unit 45A according to the present embodiment.

  In the present embodiment, the detection codes “1” to “8” are assigned to the determination units 441A to 448A of the abnormality detection unit 44 in consideration of the priority of detection of abnormality, as shown in FIG. As described above, the detection codes of the caution list are arranged in the order of the abnormality detection time. Therefore, in the caution list shown in FIG. 7, the door abnormality determination unit 442A determines that an abnormality has occurred three times at different times, and the torque abnormality determination unit 445A has generated an abnormality twice at different times. The motion abnormality determining unit 443A and the vibration abnormality determining unit 446A determine that an abnormality has occurred once each. In addition, the priority of the abnormality detection described above is set so that, for example, the detection of the abnormality related to the control system of the elevator 101 is relatively high and the detection of the abnormality related to a failure such as breakage of the elevator 101 is relatively low. Has been.

  The communication control unit 46 controls communication with the Web server 104 </ b> A of the monitoring center 104 via the network 103. Further, the communication control unit 46 transmits the caution list recorded in the caution list recording unit 45A to the Web server 104A, or the video recorded in the video recording unit 43A according to the request from the Web server 104A. A process of processing and transmitting to the Web server 104A is performed.

  Next, the display process of the caution list screen on the information processing terminal 105 according to the present embodiment will be described in detail based on the flowchart of FIG.

  As shown in FIG. 8, first, when an administrator starts the web browser 105B using the information processing terminal 105 in order to confirm the state of the elevator 101 (step (hereinafter referred to as S) 801), the web browser 105B. Connects to the Web server 104A of the monitoring center 104 via the network 103 (S802).

  In FIG. 8, after the processing of S805, the administrator determines the video that the administrator wants to check from the abnormality detection time area 53 of the attention list screen displayed on the attention list display unit 105A, and the abnormality detection time area 53 When the corresponding abnormality detection time is touch-operated, the web browser 105B accepts selection of the abnormality detection time from the administrator (S806). Next, when the Web browser 105B notifies the Web server 104A of the abnormality detection time, the Web server 104A requests the video of the abnormality detection time selected by the administrator from the communication control unit 46.

  When the communication control unit 46 receives a request from the Web server 104A, the communication control unit 46 determines a predetermined time before and after the abnormality detection time selected by the administrator from the video recorded in the video recording unit 43A (for example, the abnormality detection time). The video at 1 minute before and after is cut out and extracted (S807), and the video is transmitted to the Web server 104A. When the Web server 104A receives the video from the communication control unit 46, the Web server 104A transfers the video to the Web browser 105B.

  Next, when the web browser 105B receives the video from the web server 104A, the web browser 105B reproduces and displays the video in the video display area 541 of the video display operation area 54 in the caution list display screen of the caution list display unit 105A ( S808), the display processing of the caution list screen on the information processing terminal 105 according to the present embodiment is terminated.

  Here, since the inappropriate behavior of the passenger is different for each elevator 101, the number of detected abnormalities may be too large or too small depending on the elevator 101. In this case, since it becomes difficult for an administrator to select a video, an operation of adjusting each threshold recorded in the threshold recording units 442B to 448B using the information processing terminal 105 is performed. For example, when the Web browser 105B displays a Web page screen different from the caution list screen, the administrator can freely change each threshold value to an appropriate value by a touch operation. Thereby, it is possible to facilitate the selection of the video by the manager.

  According to the video surveillance system according to the present embodiment configured as described above, an abnormality that is an occurrence time of an inappropriate behavior of a passenger that causes a failure of the elevator 101 on the caution list screen of the caution list display unit 105A. The detection time is displayed in a list for each state corresponding to each detection code, so that the manager can easily select the target video from the caution list screen and quickly display it in the video display area 541 of the video display operation area 54. Can be played. As a result, the behavior of the passenger is confirmed from the image displayed by the manager, and if the malfunction occurs in the elevator 101 or inappropriate behavior of the passenger is seen, the manager serves as evidence. Can be instructed on how to use the elevator 101 correctly, so that it is possible to suppress the recurrence of inappropriate behavior of the passenger. As described above, the present embodiment can shorten the search time for the target video, and can appropriately provide guidance for passengers who have performed inappropriate behavior, thus preventing a failure of the elevator 101 in advance. be able to.
