Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an operating switch device for a switch installed at the entrance of a building for opening and closing a shutter.

[Prior Art and Problems to be Solved by the Invention] Conventionally, in this type of switch, an operation switch mechanism such as a three-point push button switch for selecting forward/reverse drive of the switch has been provided to open and close the shutter. It is being For reasons of safety and crime prevention, it would be a problem for these operating switches to be operated by a third party other than those involved, so conventionally the operating switches were housed in a switchbox with a locking device. etc. However, if you do this, for example, after the key manager unlocks the door and closes the shutter curtain by operating the closing operation switch, the shutter curtain that is in the closing operation with the switch box locked can be closed. There is a danger that a person or object attempting to pass under the shutter curtain may become an obstacle and get caught in the shutter curtain. It had to be locked and stopped, and as a result,
The effort required to make an emergency stop may result in an unexpected disaster.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing an operating switch device for a switch that can eliminate these drawbacks. When controlling the opening and closing by providing respective operation switches for opening, closing, and stopping, each operation switch circuit for opening and closing in which the operation switch for opening and closing is provided is equipped with a switch for opening and closing. A lock control means is provided that can be switched between an unlocked state in which the opening and closing of the switch can be controlled by the operating switch and a locked state in which the opening and closing of the switch cannot be controlled, and opening and closing control by the operating switch for opening and closing can be performed only when the lock control means is in the unlocked state. However, the stop operation switch circuit in which the stop operation switch is provided is provided independently of the locking/unlocking switching of the lock control means, so that the stop operation switch circuit can perform the stop control by the stop operation switch between the locking and unlocking of the lock control means. This feature is characterized by a structure that allows independent operation regardless of unlocking switching.

With this configuration, the present invention allows the stop switch to be operated instantly without unlocking even if the door is locked.

Reference numeral 14 denotes a diode matrix, and the diode matrix "D1 to D25" 14 decodes the push operation signals of the key switches "0" to "9" in switch box B into corresponding binary digital signals. Further, 15 is a circuit "IC1-1 to IC1-4" which acts as a buffer, and the buffer circuit 15 is necessary to receive the output from the diode matrix 14 and drive the circuit connected to the next stage. It gives the following output. This buffer circuit 15 is easily constructed using, for example, a Schmitt trigger circuit, an inverting amplifier circuit, etc., but its output terminal is connected to one input terminal of the comparison gate circuits "IC2-1 to IC2-4" 16. It is connected to one terminal of the diodes "D26-D29" 17. The other terminal of diode 17 is a decimal counter circuit with decoder "IC5"

The outputs from each of these digital switches 21-24 are wired to be supplied to the other input terminals of the comparison gate circuit 16 via diodes "D30-D75" 25-28. Furthermore, the output terminal of the comparison gate circuit 16 is connected to the AND circuit "IC
3-1" 29, and the output of the AND circuit 29 is supplied to the clock terminal of a decimal counter "IC4" 30 with a decoder.

42 is a mono multivibrator "IC6-1"
And, this mono multivibrator 42 is
It receives the output from the decimal counter circuit 30 and outputs it for a certain period of time, and its output terminal is connected to the reset terminal of the decimal counter circuits 18 and 30, respectively, and is used as a reset output, and also acts as a switch. Transistor "Tr-1"

Further, RU is an open (rise) control relay switch connected to the circuit of the opening operation switch 11 and its switch contact, and RD is the closing operation switch 1.
The closing (lowering) control relay switch connected to circuit 3, its switch contacts, and RS are:

The relay switch is connected to the circuit, and when the open/close operation switches 11 and 13 are operated, the relay

is set to open so that both circuits of the opening and closing relay switches RYU and RYD are cut off based on the fact that the relay coil of the stop control relay switch RS is excited by the switch operation of the stop operation switch 12. By these switching operations, corresponding opening, closing, and stopping controls of the shutter can be performed.

Further, numeral 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 like the above-mentioned power supply control circuit 36, a detailed explanation will be given. is 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 ``IC1-5'' 15a are inputted to the input terminal A of . Further, the output from the output terminal "9" of the decimal counter circuit 18 is inputted 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. In the mono multivibrator 39, when a signal is input to the input terminal A, the output from the output terminal Q is a transistor "Tr".
-2'' 40 becomes the 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 output 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, which similarly generates an alarm sound and resets the decimal counter circuits 18 and 30. 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. .

If it is desired to make an emergency stop during such opening/closing operations, the stop operation switch 12 can be operated at any time without unlocking. In other words, with this device, no matter how many times you operate the open/close operation switches 11 and 13, unless they are unlocked by inputting the correct number and the base current is flowing through the transistor 32, the open/close control relays will not open or close. Although no power supply current flows through the switches RU and RD, the stop operation switch 12 has a circuit configuration that is unrelated to the transistor 32.
If you operate this switch at any time, the power supply current will flow through the stop control relay switch RS to excite it.
This acts to cut off the power to the motor 37.

As described above, in the present invention, the opening/closing control of the switch 3 cannot be operated until the switch is unlocked, but the stop control does not require the unlocking operation each time. The operation when it is desired to stop becomes easier and faster, which greatly contributes to not only improved operability but also improved safety.

[Operations and Effects] In short, the present invention is configured as described above, and as long as the opening/closing operation switch can be brought into the unlocked state by always unlocking the lock control means, it is possible to operate the switch no matter how many times. However, the switch does not operate to open or close, thus reliably preventing inadvertent opening or closing operations caused by a third party's operation of the switch, and is excellent in crime prevention and safety. is not related to this lock control means and can be operated independently to stop the switch during opening/closing operation. Therefore, in case of an emergency, an emergency stop can be performed by performing the required unlocking operation for opening/closing operation control. Although this is necessary, there is no need to perform an unlocking operation, and the operation can be performed simply by operating the stop operation switch, making it possible to stop quickly and further improve safety.
