Is determined to have passed.

In SA5 of FIG. 5, the moving area monitoring unit 241 gives a voice warning that a foreign substance is present (that is, outputs a monitoring result and gives an alarm for the moving area R1). Specifically, it is optional, but for example, repeated output of a voice message from the sound device 222 in FIG. 1 (for example, a voice message such as "There is an obstacle around the fire door. Please move it immediately"). Is started to warn of the presence of foreign matter (that is, the monitoring result is output). Here, for example, the user hears the voice message from the acoustic device 222, recognizes that there is something that hinders the movement of the door portion 11, and moves the foreign matter Ob1 of FIG. 6 to the outside of the moving region R1. It becomes possible to make it.

In SA6 of FIG. 5, the moving area monitoring unit 241 determines whether or not the foreign matter has been removed. Specifically, although it is arbitrary, for example, the same processing as in the case of SA3 is performed. Then, when it is determined that the foreign matter has not been removed (NO of SA6), SA6 is repeatedly executed until it is determined that the foreign matter has been removed. If it is determined that the foreign matter has been removed (YES in SA6), the process proceeds to SA7.

In SA7 of FIG. 5, the moving area monitoring unit 241 ends the alarm. Specifically, although it is optional, for example, the alarm by the light emission that started the output to SA2 and the alarm by the voice that started the output by SA5 are terminated. Here, for example, the alarm is terminated by ending the blinking of the indicator light device 221 of FIG. 1 and turning it off, and ending the output of the voice message from the sound device 222.

Further, in SA8 after determining that the foreign matter has been removed in SA3 of FIG. 5 (YES in SA3), the moving area monitoring unit 241 ends the alarm. Specifically, although it is arbitrary, for example, the alarm by the light emission that started the output to SA2 is terminated. Here, for example, the alarm is terminated by ending the blinking of the indicator light device 221 of FIG. 1 and turning it off. This ends the monitoring process.

When only one camera device 211 or 511 is provided, the object captured by the image captured by one camera device 211 or 511 is captured three-dimensionally, or the distance to the object is measured. In order to do so, any means other than one camera device 211, 511 (for example, a known non-contact range finder that measures a distance using a laser beam) is combined to be inside the moving regions R1 and R2. It may be determined whether or not a foreign substance is present.

Further, for example, the position where the camera device 211 of FIG. 1 is installed may be arbitrarily changed, may be provided at an arbitrary position other than the position shown in the door portion 11, or the first wall portion 31 or the second wall portion 31 or the second. It may be provided on the wall portion 32.

The device 511 may be provided in the shutter accommodating portion 42.

In particular, for example, in the second embodiment, at least one camera device may be provided in the shutter accommodating portion 42 in FIG. 7 together with the two camera devices 511 or instead of the two camera devices 511. Specifically, the position on the center side of the shutter accommodating portion 42 (for example, the indicator light device in FIG. 7) with reference to the direction (X-axis direction) orthogonal to the moving direction (Z-axis direction) of the shutter curtain 41. At least one camera device may be provided near the position where 521 is shown) so that the moving region R2 can be imaged using the camera device.

The "harm prevention device" is a device for preventing a person or the like from being caught in the shutter curtain 41 when the shutter curtain 41 is lowered. The specific configuration of this hazard prevention device is arbitrary, and for example, a known configuration can be applied. For example, the tip portion 44 hits an object (person, etc.) that interferes with the descent of the shutter curtain 41. After being configured as a push switch mechanism that detects contact, the shutter curtain 41 may be configured to stop descending when it is detected that the push switch mechanism has interfered with an object. In this case, the two camera devices 511 of the second embodiment may be integrated with the tip portion 44 configured as the push switch mechanism, and the moving area monitoring unit 541 receives the detection result by the push switch mechanism. Then, when the received detection result indicates that the push switch mechanism has detected that the shutter curtain 41 has come into contact with an object (person or the like), the shutter curtain 41 may be configured to stop descending.

Since it can be handled as a unit), it is easy to handle.

(Application to fire door devices (1))
Further, the function of preventing a person or the like described in the above-mentioned "(Hazard prevention device)" from being pinched may be applied to the concept of the first embodiment. For example, the door portion 11 of the fire door device 1 is configured to be automatically opened and closed by using a drive mechanism (for example, a motor or the like), and then the door portion 11 is closed in the same manner as in the conventional case. While doing so, the moving area monitoring unit 241 determines whether or not a foreign substance exists inside the moving area R1 by performing the monitoring process shown in FIG. 5, and determines that it exists. In this case, the drive mechanism may be controlled to stop the closing of the door portion 11 for a predetermined time (for example, 5 seconds). With this configuration, for example, safety can be improved by controlling the door portion 11 based on the monitoring result of the moving area R1. Further, when the moving area monitoring unit 241 performs the same processing as the processing of SA1 in FIG. 5 to determine whether or not the door unit 11 interferes with a foreign object, and if it is determined that the door unit 11 interferes with the foreign matter, the door The unit 11 may be opened and then closed again after a lapse of a predetermined time.

(Application to fire door devices (Part 2))
Further, the function of preventing a person or the like described in the above-mentioned "(Hazard prevention device)" from being pinched may be realized by using the concept of the second embodiment. Specifically, for example, while the shutter curtain 41 is descending in the event of a fire or the like, the moving area monitoring unit 541 performs the monitoring process of FIG. 5, so that foreign matter is present inside the moving area R2. It may be configured to stop the descent of the shutter curtain 41 for a predetermined time by controlling the switch 43 when it is determined whether or not the shutter curtain is present. With this configuration, for example, safety can be improved by controlling the shutter curtain 41 based on the monitoring result of the moving area R2. Further, when the moving area monitoring unit 541 performs the same processing as the processing of SB1 in FIG. 5 to determine whether or not the shutter curtain 41 interferes with a foreign object, and if it determines that the shutter curtain 41 interferes with the foreign matter, the shutter The curtain 41 may be opened and then closed again after a lapse of a predetermined time.

(About the opening and closing direction of the shutter curtain)
Further, in the second embodiment, the case where the shutter curtain 41 of FIG. 7 opens and closes in the vertical direction (Z-axis direction) has been described, but the present invention is not limited to this, and the shutter curtain 41 opens and closes in the horizontal direction (for example, the X-axis direction). It may be configured to move.

(About unitization)
Further, with respect to the monitoring systems 2 and 5 of the first and second embodiments, the components of the monitoring systems 2 and 5 may be arbitrarily selected and unitized. For example, the housing portion 200, the camera device 211, the indicator light device 221 and the sound device 222 of FIG. 1 of the first embodiment may be integrally configured as one monitoring unit. In this case, in particular, two cameras are formed by expanding and contracting the monitoring unit by providing one camera device 211 at each end of the elongated shape after making the entire shape of the monitoring unit a stretchable long shape. The distance between the devices 211 may be adjustable.

(About monitoring results)
Further, the monitoring system 2 of the first embodiment is provided with a communication means for communicating with an external device (for example, a disaster prevention receiver or the like), and then at an arbitrary timing (for example, timing at predetermined time intervals, or The processing of SA1 of FIG. 5 is performed at the timing when the user inputs the operation input of the predetermined operation, and the determination result of the SA1 (that is, the monitoring result of the monitoring area R1) is output to the external device every time the processing of SA1 is performed. It may be sent to and output. Further, for example, if the monitoring result of the monitoring area R1 is different in the mode of light emission by the indicator light device 221 (for example, when a foreign substance is present, it emits light in red, and when there is no foreign substance, it emits light in green, etc.). It may be output by setting. Further, an alarm signal, which is a signal for specifying the alarm described in the first embodiment, may be transmitted to the external device side, and the alarm may be issued on the external device side.
