Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a switchbox device for an architectural shutter installed at the entrance of a building.

[Prior Art and Problems to be Solved by the Invention] Conventionally, some of these types of architectural shutters are installed in areas where an unspecified number of people enter and exit, such as entrances and exits of buildings. In such a device, if the opening/closing operation switch for opening and closing the shutter is exposed on the wall surface, there is a problem that an unscrupulous person may operate the switch and the security is poor.

Therefore, conventionally, the opening/closing operation switch is stored in a lockable storage box to prevent unauthorized persons from operating it easily. However, in this case, a key is always required to open and close the storage box itself, which requires key management and also means that the box cannot be unlocked unless the key is held. However, there is a risk of losing the key, and for example, when building officials go to the building for urgent business, they are unable to unlock the storage box because they do not have the key, so they have no choice but to call the administrator on the phone. , the user has to wait for the administrator who carries the key with him or her to come, which is extremely troublesome and reduces the sense of urgency.Furthermore, it is inconvenient that the shutter cannot be opened or closed if the administrator cannot be contacted. It was hot.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a switchbox device for architectural shutters that can eliminate these drawbacks. In a construction shutter configured to perform opening/closing control of the shutter based on the switch operation of a three-point push button type opening/closing/stopping operation switch, the opening/closing operation switch circuit of the circuit in which the operation switch is provided, The input number from the key switch means is connected to a lock control means that switches from a locked state to an unlocked state based on the fact that the input number digitally input from the key switch means matches a registration number registered in advance. The structure is configured such that the opening/closing operation switch can control the opening/closing of the architectural shutter when the shutter is unlocked at the same time as the opening/closing operation switch.
The present invention is characterized in that the key switch means is further provided on the box surface of the switch box in which the opening/closing/stopping operation switch is provided.

With this configuration, the present invention has excellent security in that the opening/closing operation switch cannot be operated unless the lock is unlocked, but the lock can be unlocked without having a key. It is something.

Also, 38
is a power supply circuit for supplying power to each member such as the above-mentioned relay circuits and digital circuits, but since these circuits have a general circuit configuration similar to the above-mentioned power supply control circuit 36, a detailed explanation will be omitted. .

On the other hand, 39 is a mono multivibrator "IC6
-2" and the mono multivibrator 39
The output from the AND circuit 19 and the output from the reset key switch RESET via the buffer circuit "IC1-515a" are input to the input terminal A of the decimal counter circuit 18. 9 is input to its clock enable terminal and the other input terminal of the AND circuit 19. Then, when the output from the AND circuit 19 based on receiving the output from the output terminal "9" of the decimal counter circuit 18 and the output from the diode 17 or the output from the buffer circuit 15a is received, the output is It is designed to be input to the input terminal A of the mono multivibrator 39. When a signal is input to the input terminal A, the mono multivibrator 39
Output from output terminal Q is transistor “Tr-2”
40 base current output, which energizes a buzzer "BX" (alarm device) 41 connected to the collector terminal side of the transistor 40 to emit an alarm sound.

Next, the circuit operation when a number input signal is received from the key switch means 1 will be explained. Here, it is assumed that the registration number (PIN number) is a four-digit one. When a signal is input from the key switch means 1 for pressing a key switch "0" to "9", it is decoded into a corresponding digital signal by the diode matrix 14, which becomes an input number and is sent via the buffer circuit 15. It is input to one input terminal of a comparison gate circuit 16 which determines whether the registration number matches a registration number registered in advance.
8, thereby causing the decimal counter circuit 18 to step. That is, in the key switch means 1, when the first digit is pressed, the decimal counter circuit 18 outputs from the output terminal "1", and this output is input to the digital switch 21 for the first digit. The first digit registration number has been registered in advance,
When this receives the output from the decimal counter circuit 18, it inputs the binary output corresponding to the registration number to the other terminal of the comparison gate circuit 16 for the first digit. When the signal from the digital switch 21 and the signal from the key switch means 1 match, the first digit comparison gate circuit 16 determines whether all four digits of the input number match the registration number. The output signal is output to one terminal of the AND circuit 29 which performs the operation.
Next, when the second digit is pressed, the digital switch 22 of the second digit compares the corresponding setting signal with the output from the output terminal "2" of the decimal counter circuit 18 in the same manner as described above. This signal is output to the gate circuit 16, and this signal is compared with the second digit signal from the key switch means 1 side, and if they match, it is output to the AND circuit 29. In this way, when all four digit input signals match the registered signal, AND circuit 2
9 is designed to judge that the input number matches the registration number, and the number judgment means is constructed in this way.
If it is determined that the decimal counter circuit 30 matches the above, a signal with a logic value "1" of four degrees is output to the decimal counter circuit 30 to cause it to advance. Then, the decimal counter circuit 30
is outputted from the output terminal "4" to the mono multivibrator 42, and the mono multivibrator 42 receives this and outputs a signal from the output terminal Q only during the timer time until the capacitor "C5" is discharged, As a result, the decimal counter circuit 1
8 and 30, and during this timer time, a base current is applied to the transistor 32 to turn the transistor switch ON and into the unlocked state, and the display lamps 8 and 9 are lit, and the opening/closing operation switch is turned on. It is possible to control the opening and closing of the shutter based on the operation of the switches 11 and 13, and in this way, the lock control means for switching the operation of the opening and closing operation switches 11 and 13 between the locked and unlocked states, and the An unlocking operation restriction means for restricting time is configured.

On the other hand, if there is an error in the input number from the key switch means 1, the input signals at the comparison gate circuit 16 do not match, and therefore there is no logical value "1" output from the AND circuit 29, but the decimal counter circuit 1
In step 8, it advances in accordance with the number of times the button is pressed. When the push operation is repeated nine times, an output is output from the output terminal "9" of the decimal counter circuit 18 to the AND circuit 19. The AND circuit 19 receives this output signal and the signal that has passed through the buffer circuit 15 due to the push operation from the key switch means 1, and outputs a signal with a logic value of "1", and when this is input to the mono multivibrator 39, the monomulti The vibrator 39 outputs a base current signal to the transistor 40 for a certain period of time until the capacitor "C1" is discharged, and energizes the buzzer 41 to emit an alarm sound, thus forming alarm issuing means. There is.

Furthermore, when the reset key switch RESET is pressed, the signal is directly input to the mono multivibrator 39, and an alarm is emitted in the same way, and the decimal counter circuits 18 and 30 are reset. It is set to do so.

In the embodiment of the present invention configured as described above, when opening and closing the shutter by driving the motor 37 provided in the switch 3 in the forward and reverse directions, a number is input from the key switch means 1 to unlock the lock control means. It needs to be locked. In other words, in this device, a necessary multi-digit number is input from the key switch means 1, but if the number judgment means judges that all of these multi-digit input numbers are correct, the device that receives this output When the multivibrator 42 flows a base current to the transistor 32, the transistor 32 is in a drive state, that is, the transistor switch is turned on and switched to an unlocked state, and thereby the open/close operation switch 11, A state is reached in which opening and closing control of the shutter by operating the switch No. 13 is permitted. Therefore, in this unlocked state, the motor 37 is driven in forward and reverse directions in conjunction with the operation of either the opening operation switch 11 or the closing operation switch 13, and the opening and closing control of the shutter is performed. . As a result, there is no need to carry and manage keys one by one as in the past. Regarding the stop operation switch 12,
It can be operated at any time by entering a number without having to unlock the door each time.

In this way, when opening and closing the shutter by driving the motor 37 in forward and reverse directions, first input a number using the key switch means 1 to bring it into the unlocked state.
You will have to operate the opening/closing operation switches 11 and 13, but all the switches for unlocking and opening/closing stop operations are operated by switch box B.
are concentrated on the box surface.

As a result, when operating the opening/closing operation switches 11 and 13, a key is no longer required as in the past, and even if you do not know the correct number, you can inquire by phone etc. By inputting the following information, you can quickly and reliably unlock the shutter and control the opening and closing of the shutter at any time. Furthermore, since the shutter remains locked when no number is entered, even if an unscrupulous person tries to open or close the shutter, it will not be unlocked, and security will not be compromised.

Moreover, with this device, only the opening/closing operation switches 11 and 13 are locked, and the stop operation switch 12 is always maintained in an unlocked state without being locked, so it cannot be opened or closed. When making an emergency stop of the shutter, there is no need to perform an unlocking operation each time, and the emergency stop can be made quickly, improving safety.

And operation switches 11, 13 for opening and closing after unlocking
The operation is limited to a certain period of time until the capacitor C5 installed in the mono multivibrator 42 is discharged, and after this time the unlocked state is reset and the locked state is restored, so it is important to enter the correct code number. Even if the administrator enters the key and leaves it unlocked, and the administrator leaves, the door will be automatically locked to prevent a third party from opening or closing the door. Safety and crime prevention can be ensured, and the integrity of opening/closing management can be further ensured.

[Operations and Effects] In summary, since the present invention is configured as described above, when operating a three-point push button type operation switch to control opening and closing of the shutter, the switch provided with the operation switch can be used. This is done after inputting a number from the unlocking key switch means similarly provided on the surface of the box to unlock it.Therefore, an operating switch for opening/closing/stopping is installed inside the conventional keyed storage box. There is no need to have a key to unlock the storage box, as in the case of a storage box, and if a person other than the administrator who does not know the correct number wants to enter or exit in an emergency, it is possible to make a phone call. Now you can make inquiries such as the following, and you don't have to wait for the manager to come. Moreover, you can unlock the lock quickly and reliably by inputting a number without worrying about losing it, and you don't have to worry about the troubles of the past. There is no need to manage the possession of keys at all, which is highly desirable not only in terms of operability but also in terms of management.

Moreover, in this device, the key switch means for unlocking the lock can be provided on the box surface of the switch box in which the three-point push-button operation switch for opening/closing/stopping is provided, in the same way as the aforementioned operation switch. The storage box with a lock can be eliminated since it can be stored in a general-purpose storage box that does not have a lock, or it can be installed without a storage box.
