In the drawings, reference numeral 1 denotes a shutter curtain of an electric shutter, and the shutter curtain 1 includes an electric motor 2
The opening and closing of the opening is performed by vertically moving up and down along guide rails (not shown) on both right and left sides of the opening by the winding and rewinding operations of the winding drum 3 accompanying the forward and reverse driving of the opening and closing. All configurations are the same as before.

人体検知を行うよう構成されている。On the other hand, reference numeral 4 denotes a hot-wire detection sensor mounted on the ceiling. The hot-wire detection sensor 4 detects a person in the detection area based on a difference between far-infrared energy radiated by a human body and radiant energy of the surroundings. The detection area is divided into a plurality of (three or more) detection areas arranged in parallel in the traffic direction of a person, and a human body is detected for each detection area.

The control unit 5 is configured by using a microcomputer (microprocessor, memory) or the like. (Open, stop, close) push button switch PBU, PBS, PBD, upper and lower limit switch LSU,
LSD and signals from the hot-wire detection sensor 4 and the like are input, and the electric motor 2 is determined based on these input signals.
An operation signal is output to the controller.

規制するようになつている。Next, the control procedure of the control unit 5 will be described with reference to a flowchart shown in FIG. 5. In the control of the control unit 5, the electric motor 2 is controlled based on the operation of the remote control push button switches PBU and PBD. Conventionally, the shutter curtain 1 is opened and closed by the forward and reverse driving, and the opening and closing operation is stopped based on the operation signal of the push button switch PBS or the detection signal of the upper and lower limit switches LSU and LSD. In this case, particularly, at the time of the closing operation, the operation is stopped based on the detection of the hot-wire type detection sensor 4, but when the electric motor 2 is not operated, the intrusion of a person into the detection area and the Push button switch for closing by judging the intrusion of the intruder in the detection area
The closing operation of the shutter curtain 1 based on the operation of the PBD is regulated.

カーテン１の閉鎖作動を規制するようになつている。That is, when the electric motor 2 is inactive while the shutter curtain 1 is open, it is first determined whether or not the detection area of the hot-wire detection sensor 4 is in non-detection. Here, if the determination is YES, the closing operation of the shutter curtain 1 based on the operation of the above-mentioned closing push button switch PBD is permitted, but if the determination is NO, the detection area or the detection state is detected. It is determined whether the state has been switched to the non-detection state. In other words, in this judgment,
It is determined whether a person who has entered the detection area has passed through the detection area or has exited the detection area, but it is not possible to distinguish between intrusion and exit only by this determination.
If the determination is YES, it is determined whether the detection area is in the non-detection state. If both the determinations are YES, it is determined that the person has left the detection area, and the closing operation of the shutter curtain 1 based on the operation of the closing push button switch PBD is permitted. If the determination is NO, it is determined that a person has entered or is stationary in the detection area, and the closing operation of the shutter curtain 1 based on the operation of the closing push button switch PBD is regulated. I'm sorry.

この結果、電動シヤツターの安全性が向上する。In the embodiment of the present invention configured as described above,
When a person enters the detection area of the hot-wire detection sensor 4, it is determined whether or not there is a stationary person based on the determination of whether or not the person has left the detection area. Even if the hot-wire detection sensor 4 is switched to the non-detection state due to the stabilization of the far-infrared energy due to the stillness of the person inside, the closing operation of the shutter curtain 1 based on the operation of the closing push button switch PBD is performed. It can be regulated reliably. Accordingly, it is possible to prevent a disadvantage that the shutter curtain 1 is closed without notice of a stationary person such as a drunk person as in the related art,
As a result, the safety of the electric shutter is improved.

ア内での人の静止を判断することになる。[Effects] In summary, since the present invention is configured as described above, a change in far-infrared energy due to the movement of a person is detected by a hot-wire detection sensor, and based on the detection, the opening and closing of the opening and closing body is performed. While restricting the closing operation, when detecting the intrusion of a person into the intermediate detection area among the three or more divided detection areas, the intrusion of a person into other detection areas sandwiching the intermediate detection area is prevented. The detection determines whether the person is still in the detection area.

防止して安全性の向上を計ることができる。Therefore, even if the hot-wire detection sensor is switched to the non-detection state due to the stabilization of the far-infrared energy due to the stillness of the person, it is possible to regulate the closing operation of the opening / closing body. It is possible to prevent a problem that the opening / closing body is closed without noticing a stationary person such as a drunk person, thereby improving safety.
