Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a CD service corner equipped with a cash dispenser at a cash handling place such as a bank, a store such as a department store, or a warehouse or factory. (E.g., electric) shutter provided at the entrance of a building such as a garage, etc., which not only performs manual opening / closing control operation, but also performs unattended automatic opening / closing control by remote control from a program control or a management center. And automatic adoption of such an unmanned automatic opening / closing control system makes it possible to secure the unmanned automatic opening / closing control based on the detection result of the presence or absence of the occupants (residuals in the building). The present invention relates to a safety shutter configured to be able to execute.

[Conventional technology]

As a conventional safety shutter of this type, for example, there has been proposed a shutter disclosed in Japanese Patent Application Laid-Open No. 60-192078, which is related to Japanese Patent Application No. 59-48780.

That is, in the conventional safety shutter, an occupant detector (for example, an infrared detection sensor) for detecting whether or not a person remains inside the interior of the shutter (in the building) is provided in the building. As schematically illustrated in FIG. 10, when the main control device for the shutter opening / closing controller receives a closing command signal by an operation switch or automatic control, the occupant detector is turned on. If the occupant detection signal is not output, the lowering control circuit is operated to lower the shutter curtain to the lowermost limit and control to completely close the shutter, but the occupant detector detects the occupant detection signal. If so, the lowering control circuit should not be started, and the lowering operation of the shutter curtain should be completely prohibited, and the abnormality notification circuit should be activated as necessary. Controls to more Problem the abnormality to the management center or the like, the control structure that has been adopted. In FIG. 10, 0S1 is a switch that is turned on by the closing command signal, 0S2 is a switch that is turned off by a lower limit detection signal from a lower limit detection sensor indicating that the shutter curtain has been lowered to the lower limit, and , 0S3 denote switches that switch from the descent control circuit side to the abnormality notification circuit side according to the occupant detection signal.

[Problems to be solved by the invention]

According to the above-described safety shutter having the conventional configuration, when a person remains inside the shutter (in the building), the shutter curtain does not perform any lowering operation even if a closing motion command signal is given. Therefore, although the purpose of ensuring safety can be sufficiently achieved, there are still problems in the following points.

That is, for example, in the CD service corner of a bank,
In spite of the fact that the operation of machines such as cash dispensers and the like has already stopped at the closing time and announcements that the store is closed have been made, in addition to the fact that it is usually during congestion, Because the safety control does not cause the shutter curtain to descend at all, the customer does not readily notice that the store is closed and does not readily exit,
The above-mentioned safety control is continued as it is, and there is a tendency that an inconvenience such that the shutter curtain does not operate indefinitely occurs frequently. However, there is a large amount of cash in the CD service corner, so it is necessary to ensure the security of it, and it is necessary to minimize violations of business closing hours strictly stipulated by Article 15 of the Banking Law. Is very important, for example, when the above-mentioned inconvenient situation occurs, the abnormal situation is automatically notified relatively quickly to the management center or the like. Therefore, from the management center side, every time an abnormal situation often occurs due to such a mere delay in leaving the customer, the person in charge rushes to the site (the store where the abnormality was reported) one by one, and It is necessary to perform a very cumbersome and complicated processing operation of prompting the main controller to re-open the main control device with the manual operation switch after prompting the evacuation of the residual person who caused the abnormality and confirming the completion of the evacuation. However, the advantages of the unattended automatic control system were not fully utilized, and the burden on the administrator was extremely large.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and has as its object to control a vehicle that can sufficiently maintain a required safety control function and that can surely promote a prompt exit of a room occupant. An object of the present invention is to develop and provide a safety shutter capable of fully utilizing the advantages of the original unmanned automatic control system by providing the means.

[Means for solving the problem]

In order to achieve the above object, a safety shutter according to the present invention is a safety shutter provided with an occupant detector, as schematically shown in the claim correspondence diagram of FIG.
When the occupant detector does not output the occupant detection signal when the closing operation command signal is received, control is performed such that the shutter curtain is lowered to the lowermost limit and the shutter is fully closed, and When the occupant detector outputs the occupant detection signal, a control means is provided for controlling the shutter curtain to lower to a predetermined halfway height and then stop to prompt the occupant to exit. There is a feature.

In FIG. 1, S1 is turned on by a closing command signal.
S2 is a switch means that is turned off by a lower limit detection signal from a lower limit detection sensor indicating that the shutter curtain has been lowered to the lower limit.
The emergency processing control means (lower the shutter curtain to a predetermined halfway height) from the normal lowering control means (control means for lowering the shutter curtain to the lowermost limit and fully closing the shutter) from the occupant detection signal Switch means for switching to the control means) for stopping the operation after stopping.

[Action]

The function to be exhibited due to such a characteristic configuration is as follows.

That is, according to the safety shutter according to the present invention, as is clear from the description of the embodiment described later, for example, when a predetermined closing time comes and a closing operation command signal is given, Even if occupants remain in the building, the shutter curtain lowering operation is not completely prohibited as in the past, but the shutter curtain lowering operation ignores the occupant detection signal for the time being. And control means for controlling the shutter curtain to descend to a predetermined halfway height and then stopping, so that the closing time has come due to the movement of the shutter curtain and the accompanying sound, etc. Ensure that the occupants of the room must be exited immediately (under a somewhat warning atmosphere) and promptly Therefore, for example, by setting the height during the stop of the shutter curtain to a height at which the occupant can pass sufficiently (however, in the embodiment described later, another method such as raising again after the fact) Is also shown), and the occupant can be quickly and smoothly exited outside the shutter curtain without being confined in the building. Then, since the occupant can be reliably and promptly exited as described above, thereafter, the occupant detector stops outputting the occupant detection signal, and the shutter curtain follows the normal descending control sequence. The shutter is lowered to the lowest limit, and the shutter is fully closed almost as scheduled.

In this way, it is possible to almost completely eliminate the inconveniences that have frequently occurred in the past, such as the continuation of abnormalities caused by mere delay in leaving a customer and the notification thereof, and thus the required safety control function is sufficiently provided. While maintaining the above, the advantages of the original unmanned automatic control system can be fully utilized, and the burden on management personnel can be significantly reduced. It can be prevented.

A rolled copper 4A for winding the curtain 1 is rotatably mounted on a shaft, and a shutter opening / closing device 5 (forward / reverse rotating electric motor) capable of driving the rolled copper 4A forward / reversely via, for example, a chain transmission mechanism 4B. (Comprising a motor 5A and a transmission 5B). The shutter opening and closing device 5 is configured to be controlled by a main control device C provided in a control panel via a shutter opening and closing controller A. Reference numeral B denotes a manual operation switch provided on the wall surface of the room, which includes a push button for an opening command, a push button for a stop command, and a push button for a closing command.

The speaker device D includes a speaker driving circuit 6 and a speaker 7, and the alarm device E is an alarm device driving circuit 8 and an alarm device. (In this example, a buzzer) 9. The main control device C is also connected to a central control device H on the management center Y side via a communication device F on the building X side and a communication device G on the management center Y side. This management center Y is located at a place separated from each building X by contracting with a security company or the like, for example, so that automatic or manual remote centralized management of many buildings X can be performed. It has been installed.

Further, an obstruction detector 10 that emits an obstruction detection signal when detecting the presence of the obstruction S is attached to a substantially entire lower surface of the seat plate 1A of the shutter curtain 1 in the longitudinal direction. That is, in this example, the obstacle detector 10 forms a space 11 having a predetermined (slight) vertical space on the lower surface side of the seat plate 1A of the shutter curtain 1 as shown in detail in FIG. A contact (crimping) -operated sensor comprising an exterior member 12 made of a flexible material such as rubber and attached, and terminal plates 13 and 14 fixed to upper and lower surfaces in the space 11, respectively. As shown in FIG. 5, no matter which part of the obstacle detector 10 contacts the obstacle S, the contact part of the exterior member 12 to the obstacle S is moved upward by the obstacle S. By being pressed and deformed, the upper and lower terminal boards 13 and 14 are pressed against each other to generate an obstacle detection signal. The obstacle detection signal emitted by the obstacle detector 10 is transmitted to a wireless transmitter (light emitter in this example) 15 installed on the upper surface of the seat plate 1A and the shutter case 3 so as to face the wireless transmitter 15 (light emitter). It is configured to be transmitted to the main controller C via a wireless receiver (light receiver in this example) 16 installed on the lower surface of the shutter curtain 1, as will be described later in detail. If the obstacle detector 10 generates an obstacle detection signal due to the presence of the obstacle S during the lowering operation, the lowering operation of the shutter curtain 1 is immediately stopped immediately. In addition, this obstacle detector
The configuration 10 is not limited to the configuration described above, and other configurations such as a system that detects a change in capacitance or resistance value due to contact of the obstacle S may be used.

Further, as shown in FIG. 2, a sensor (a limit switch in this example) L1 for detecting the position (the height of the lower end) of the shutter curtain 1 is provided on one of the left and right guide rails 2, 2. , L2, L3, L4. That is, L1 is an upper limit position detection sensor for detecting that the shutter curtain 1 has risen to the upper limit (fully open state), and L2 detects that the shutter curtain 1 has fallen to the lower limit (fully closed state). L3 is a lower set position detecting sensor for detecting that the shutter curtain 1 has been lowered to a lower set height H1 (for example, about 1 to 1.5 m through which a person can pass). And L4 is the shutter curtain 1 at the upper halfway set height H2 (for example, lower than the lower halfway set height H1).
(Upper position of about 20 to 30 cm) is an upper set position detection sensor for detecting that the position has been raised. The detection signals from these position detection sensors L1, L2, L3, L4 are transmitted and input to the main controller C. It is configured to: In addition,
Among these, the upper limit position detection sensor L1 is used for natural control to stop the raising operation unconditionally when the shutter curtain 1 rises to the fully opened state, and the lower limit position detection sensor L2 is used for the shutter It is also used for natural control to stop the lowering operation unconditionally when the curtain 1 is lowered to the fully closed state. The remaining lower set position detection sensor L3 and upper set position detection sensor L4 is used in the emergency processing control means according to the gist of the present invention, as will be described later, but if the upper limit position detection sensor L1 is also used as the upper set position detection sensor L4, the upper set position detection is performed. The sensor L4 can be omitted, and when the emergency processing control means is executed by time control, the lower set position detection sensor L3 and the upper set Both the position detection sensor L4 can be omitted.

Furthermore, as shown in FIG. 3, in order to detect whether or not a person remains inside the interior of the safety shutter (in the building X), for example, an occupant having an infrared detection sensor is used. Detector 17 (however, another type such as an ultrasonic detection sensor or a photoelectric tube may be used) is used for building X
The occupant detection signal is transmitted and input to the main controller C.

The components (members) described above are connected as shown in the overall system configuration diagram of FIG. 6, and the main control configuration and operation of the main control device C in this system configuration are shown in FIG. Is as shown in the detailed block circuit configuration diagram of FIG.

That is, as shown in FIG. 7, the main control device C is a basic control circuit which is provided by a manual operation on the operation switch B or a remote instruction from the management center Y side via the communication device F. A normal lowering control circuit, a normal raising control circuit, and a normal stop control circuit for performing normal lowering drive control, ascending drive control, and drive stop control for the shutter curtain 1 are provided based on a motion command signal, an opening motion command signal, and a stop command signal. In addition, when performing the descent control for the shutter curtain 1, the building X
An emergency processing control circuit for performing processing control when a room occupant remains, an emergency processing control circuit for performing processing control when an obstacle exists below the shutter curtain 1, And an abnormality notification signal generation circuit for performing processing control (reporting to a predetermined organization such as the management center Y) when the processing control by the emergency processing control circuit is not completed even after a predetermined time has elapsed. The following switches are connected to each circuit.

That is, in FIG. 7, S1 is determined by the closing command signal.
A switch that operates ON, and S2 is the lower limit detection sensor.
L1 is a switch that is turned off when a lower limit detection signal indicating that the shutter curtain 1 has been lowered to the lowermost limit is given. S3 is a switch in which a person remains in the building X by the occupant detector 17. Is a switch that switches from the normal descending control circuit side to the emergency processing control circuit side when a occupant detection signal indicating that the vehicle is in the room is detected. S4 is an obstacle below the shutter curtain 1 by the obstacle detector 10 Is a switch that switches from the normal descending control circuit side to the emergency processing control circuit side when an obstacle detection signal indicating that the emergency processing control circuit is present is provided. When a time-up signal indicating that the processing has not been completed even after the elapse of time has been given by a timer (not shown) built in main controller C, an emergency notification signal is sent from the emergency processing control circuit side. S6 is a switch that switches to the generation circuit side, and S6 is an emergency processing control circuit when a time-up signal indicating that processing control by the emergency processing control circuit is not completed even if a predetermined time has elapsed is given by the timer. Is a switch that switches from the side to the abnormality notification signal generation circuit side, and S7 is a switch that is turned ON by an opening command signal, and S8 is that the shutter curtain 1 has risen to the maximum upper limit by the upper limit detection sensor L1. When the upper limit detection signal shown is given
A switch that is turned off, and S9 is a switch that is turned on by a stop command signal.

According to the above configuration, when the closing operation command signal is given, the switch S1 is turned ON (the switches S7 and S9 are turned off.
If there is no problem (unless an occupant or an obstacle is detected), the switches S3 and S4 are normally switched to the lowering control circuit side. The shutter opening / closing controller operates the alarm device (buzzer) 9 by the alarm device driving circuit 8 until the lower limit detection signal from the lower limit detection sensor L2 indicating that the sensor has dropped to the lower limit is given and the switch S2 is turned off. 5 controls the shutter curtain 1 to move down to the lowermost limit and to fully close the shutter.

However, when the occupant detection signal indicating that a person remains in the building X is provided by the occupant detector 17 in spite of the provision of the closing command signal, the switch is turned on.
Since S3 is normally switched from the descending control circuit side to the emergency processing control circuit side, the emergency processing control circuit operates, and first, the alarm device driving circuit 8 operates the alarm (buzzer) 9. Even if the occupant detection signal is given by the occupant detector 17, the lowering operation of the shutter curtain 1 is not completely prohibited, but the shutter opening / closing controller 5 controls the shutter curtain 1 for the time being. , Is lowered to the lower set height H1 shown in FIG. 2 (until the lower set position detection sensor L3 is activated, or until the time corresponding thereto elapses), and then at the lower set position. Once stopped (predetermined time: for example, about 10 seconds), and the speaker 7 is operated by the speaker drive circuit 6, for example, "The shutter closes automatically because the store closes. The customer immediately exits. Please make an announcement such as "Please." Then, while operating the alarm (buzzer) 9 again by the alarm drive circuit 8, the shutter opening / closing controller To raise the shutter curtain 1 to the upper set height H2 shown in FIG. 2 (until the upper set position detection sensor L4 is activated or the time corresponding thereto elapses), and then set the upper At the position, stop again (predetermined time: for example, about 10 seconds) and activate the speaker 7 by the speaker drive circuit 6 to make an announcement, for example, "Shutter will be completely closed soon so please exit immediately." Is controlled to repeat the operation of prompting the customer to leave.

Then, if the customer exits promptly by such a control operation, the occupant detection signal from the occupant detector 17 is not given, and the switch S3 returns to the normal lowering control circuit side, and the normal The shutter curtain 1 descends to the lower limit by the descending control, and the shutter is completely closed.
Even if the emergency processing control operation as described above is repeated for a predetermined time (for example, several minutes: determined by the load limit of the motor 5A of the shutter opening / closing device 5, the limit by law, rule, or the like), the customer does not leave ( When the occupant detection signal from the occupant detector 17 is not lost, the switch S3 is still switched to the emergency processing control circuit side).
The switch S5 is switched to the abnormality notification signal generation circuit side by the time-up signal from the timer, and the abnormality notification signal generation circuit is activated. The notification is sent to a predetermined organization such as the management center Y via F.

Further, during the lowering of the shutter curtain 1 to the lowermost position by the normal lowering control circuit,
When an obstacle detection signal indicating that an obstacle exists below the shutter curtain 1 is given by the obstacle detector 10, the switch S4 switches the normal lowering control circuit to the emergency processing control circuit. Therefore, the emergency processing control circuit is operated, and first, the lowering operation of the shutter curtain 1 is immediately stopped, and then, while the alarm device (buzzer) 9 is operated by the alarm device driving circuit 8, the shutter opening / closing controller is operated. 5, the shutter curtain 1 is moved to the uppermost position (the upper limit position detection sensor L1 shown in FIG. 2).
) Until the shutter is fully opened and then the alarm drive circuit 8 again activates the alarm (buzzer)
The operation of lowering the shutter curtain 1 by the shutter opening / closing controller 5 while operating the shutter 9 is controlled so as to be repeated.

Then, if the obstacle is removed while performing such a control operation, the obstacle detection signal from the obstacle detector 10 is not given, and the switch S4 returns to the normal descending control circuit side, and the above-described operation is performed. Normally, the shutter curtain 1 is lowered to the lowermost limit by the lowering control, and the shutter is completely closed. However, if the above-described emergency processing control operation is performed for a predetermined time (for example, several minutes: the motor 5A of the shutter opening / closing device 5).
The obstacle is not removed even if it is repeated (determined by the load limit of the switch) (an obstacle detection signal is not lost by the obstacle detector 10 and the switch S4 is still switched to the emergency processing control circuit side), and an abnormal situation occurs. If the switch
S6 is switched to the abnormality notification signal generation circuit side by the time-up signal from the timer, and the abnormality notification signal generation circuit is activated, so that, for the first time, the occurrence of an abnormality due to the presence of an obstacle that could not be resolved via the communication device F This is reported to a predetermined organization such as the management center Y.

When the opening command signal is given, the switch
S7 is turned on (switches S1 and S9 are turned off), the normal ascending control circuit is operated, and a lower limit detection signal is supplied from an upper limit detecting sensor L1 indicating that the shutter curtain 1 has risen to the maximum upper limit. The shutter opening / closing controller 5 raises the shutter curtain 1 to the upper limit and controls the shutter to fully open while the alarm device driving circuit 8 operates the alarm device (buzzer) 9 until the device is turned off.

When a stop command signal is given, the switch
S9 is turned ON (switches S1 and S7 are turned OFF), and the normal stop control circuit is operated to immediately and unconditionally operate the shutter curtain 1 regardless of whether it is moving up or down. The operation is controlled to stop.

FIGS. 8 and 9 show another embodiment, in which the main control unit C (control panel) is constituted by using a CPU, a memory and the like as shown in FIG. It is something that can be done. According to such a configuration, as is clear from the example of the flowchart of the control sequence shown in FIG. 9, it is possible to perform various controls similar to those in the above-described embodiment, and, of course, store the control program corresponding to the annual business schedule in the memory. Is stored in advance, or there is an advantage that various advanced control systems can be constructed by bidirectional communication with the management center Y.

As shown by the broken line in the flowchart of FIG.
The emergency processing operation may be continued again without terminating the control as long as the trouble does not occur.

〔The invention's effect〕

As is apparent from the details described above, according to the safety shutter of the present invention, when the closing motion command signal is received, even if the occupant detector outputs the occupant detection signal, Rather than completely prohibiting the lowering operation of the shutter curtain as in the past, the control of ignoring the occupant detection signal for the time being, starting the shutter curtain downward, lowering it to a predetermined halfway height, and then stopping it For example, even if a occupant remains in the building when the store is closed, the shutter curtain must be moved and the sound associated with it has to close the store and immediately leave the building. The occupants can be surely and promptly recognized in a somewhat warning atmosphere to the occupants. For example, by setting the height at which the occupants can pass sufficiently, the occupants can pass under the shutter curtain reliably and smoothly without being trapped in the building. The shutter curtain can then be lowered to the lower limit in accordance with a normal lowering control sequence, and the shutter can be fully closed almost as scheduled, thereby simply exiting the customer. It is possible to almost completely eliminate the inconveniences that have occurred frequently, such as the continuation of abnormalities caused by the delay for a long time and the notification of such abnormalities, while maintaining the required safety control functions sufficiently, You can take full advantage of the automatic control system,
As a result, it is possible to significantly reduce the burden on the management staff and to surely prevent unintended violations of laws and regulations.
