A plurality of cameras and sensors (not shown) are communicably connected to the monitor control device 40, and the monitor control unit 451 collects information obtained by the cameras and sensors. The monitoring control unit 451 generates a screen (monitoring screen) for viewing information obtained by cameras and sensors, and outputs the screen through the output unit 43 . The monitoring control unit 451 determines whether there is an abnormality in the equipment based on the collected information, and outputs the determination result via the output unit 43 . When it is determined that an abnormality has occurred, the monitoring control unit 451 outputs information regarding the abnormality to the operator. For example, the monitoring control unit 451 may output information indicating the type of abnormality, the location where the abnormality has occurred, and the details of the abnormality. The monitoring control unit 451 also transmits information obtained by cameras and sensors to the remote monitoring control device 50 via the network 60 .

The tracking unit 452 tracks the position of each worker based on multiple images inside the target facility 90 obtained from multiple imaging devices 10 . The tracking unit 452 records the tracking result of the position of each worker in the storage unit 44 . The tracking result may be information including location information and time information, for example.

The abnormality determination unit 453 determines whether an abnormality has occurred in the situation of each worker in the monitoring target facility 90 . The anomaly determination unit 453 may determine the occurrence of an anomaly of the worker, for example, based on biological information received from the terminal device 30 possessed by each worker. The abnormality determination unit 453 may determine the occurrence of abnormality in the worker based on the image obtained by the imaging device 10 . For example, the abnormality determination unit 453 may determine whether an abnormality has occurred in the worker based on the tracking result of the tracking unit 452 .

The abnormality determination unit 453 may perform different handling processes depending on the type of abnormality determined. For example, when an abnormality indicating that the worker is drowsy is determined, a preset process may be executed to wake the worker from drowsiness. Specifically, the abnormality determination unit 453 outputs the voice representing the name of the worker to the terminal device 30 owned by the worker or the voice output device 20 installed near the position of the worker. You can output from At this time, the abnormality determination unit 453 may output an alarm sound or voice (for example, "Get up") corresponding to the drowsiness. In addition, if the storage unit 44 defines a coping process such as an alarm sound that differs for each worker, the abnormality determination unit 453 may perform processing for the worker determined to be abnormal according to the definition. . In addition, the abnormality determination unit 453 records a history of determinations of drowsiness for each worker. You may perform the process according to the conditions which were set. For example, the abnormality determination unit 453 may output the sound information at a higher volume as the number of times sleepiness is determined increases.

The abnormality determination unit 453 outputs identification information indicating the worker to the output unit 43 of the monitoring control device 40 when it is determined that an abnormality has occurred, which is defined in advance as a situation in which it is difficult for the worker to continue working. may As a specific example of such a situation, for example, when the value indicated by the biological information (pulse, blood pressure, body temperature, heart rate, respiratory rate, etc.) exceeds a predetermined threshold, or when the worker is lying down in the image. It may be detected, or the worker's position may not change for a given period of time. Whether the worker's position does not change over a predetermined period of time may be determined based on the tracking result of the tracking unit 452, for example. It may be determined based on the fact that the worker is not shown (not detected) in the image captured by 10 for a predetermined period of time or longer. These conditions may be defined in combination. For example, if the value indicated by the biological information (pulse, blood pressure, body temperature, heart rate, respiratory rate, etc.) exceeds a predetermined threshold and the worker's position does not change for a predetermined period of time, it is assumed that an abnormality has occurred. may be determined.

The abnormality determination unit 453 receives information indicating the determined abnormality, identification information (for example, name) of the worker determined to be abnormal, information indicating the position of the worker determined to be abnormal, and photographing the position. The image data obtained from the imaging device 10 within the area may be output to the output unit 43 . In this case, the abnormality determination unit 453 may transmit these pieces of information to the terminal device 30 of another worker who is different from the worker whose occurrence of the abnormality has been determined. In addition, the abnormality determination unit 453 may control the terminal device 30 of the worker determined to have an abnormality to perform a predetermined operation for the purpose of awakening the worker. . For example, the abnormality determination unit 453 may output an acoustic signal such as an alarm from the output unit 43 (speaker) of the terminal device 30 of the worker determined to have an abnormality, or output a voice indicating the name of the worker. You can output. At this time, the abnormality determination unit 453 may output the acoustic signal or the sound at a louder volume than when the abnormality of drowsiness is determined. The abnormality determination unit 453 may operate a vibrator provided in the terminal device 30 of the worker determined to have an abnormality. The abnormality determination unit 453 may cause the audio output device 20 installed near the worker whose abnormality has been determined to output a voice representing the name of the worker or an acoustic signal indicating an alarm. In this case as well, the abnormality determination unit 453 may output the acoustic signal or voice at a louder volume than in the case where the drowsiness abnormality is determined. By configuring in this way, it is possible to increase the possibility that the worker who has been determined to be abnormal will wake up, and to notify other workers who have come to look for the position of the worker who has been determined to be abnormal. It is also possible to notify by In addition, for example, even if a worker is positioned in a toilet (especially in a private room of the toilet) or in a place that is likely to be a blind spot, it is possible to determine whether or not an abnormality has occurred. If there is a problem, it is possible to correctly inform other workers about it and its location. Especially in a place where it is easy to get cold, such as a toilet, the onset of myocardial infarction is likely to occur.

4 and 5 are diagrams showing specific examples of screens displayed on the monitor control device 40 or the terminal device 30 under the control of the abnormality determination section 453. FIG. For example, as shown in FIG. 4, the screen shows an image showing a map near the current position of the worker (Mr. Takashi) whose abnormality was determined among the maps of the monitor control device 40, and the position of the worker. An image and an image showing the identification information (name) of the worker may be displayed. For example, as shown in FIG. 5, an image obtained from the imaging device 10 may be displayed in which the position of the worker determined to be abnormal is within the imaging area. In this image, you can see the worker (Takashi) lying down in the back of the screen. Furthermore, information indicating the position (for example, "second floor north side") may be displayed.

When the abnormality determination unit 453 determines that the worker is abnormal, the abnormality determination unit 453 requests the remote monitoring control device 50 to temporarily perform a part or all of the functions executed by the monitoring control unit 451 of the own device. A signal (hereinafter referred to as a “monitoring proxy request signal”) is sent to the remote monitoring control device 50 . When the remote monitoring control device 50 receives the proxy monitoring request signal, the monitoring work being performed by the operator of the monitoring control device 40 who sent the proxy monitoring request signal is performed by the user (observer) of the remote monitoring control device 50. A part or all of the screen displayed on the monitor control device 40 is controlled to be output by the remote monitor control device 50 so that it can be executed by the remote monitor control device 50 . In this case, for example, it may be configured to transmit more information to the remote monitoring control device 50 than before the proxy monitoring request signal is transmitted. With this configuration, another worker (originally, the worker who is operating the monitoring control device 40) moves to the location of the worker where the abnormality occurred, so that the monitoring control device 40 can be operated normally. Even if it becomes difficult to operate, the remote monitoring control device 50 can take over or assist in normal operation. Therefore, even if the number of workers in the monitoring target facility 90 is small, it is possible to achieve both rescue of the worker determined to be abnormal and normal operation of the monitoring target facility 90 .
