[0001]

[Field of Industrial Application] The present invention is a gate, garage, etc. that is installed in a gate, garage, etc., and automatically opens and closes these doors, etc. by remote control, and also activates the lighting etc. The present invention relates to an automatic opening / closing device.

[0002]

2. Description of the Related Art Conventionally, in an apparatus for opening and closing a door such as a gate and a garage (hereinafter referred to as a gate) by driving an electric motor,
It was driven by a manual switchgear or a remote-controlled automatic switchgear. By the way, when the manual opening / closing device is used, the operation is easy and the cost is low, but when returning home by car, it is inconvenient to get off the vehicle and go to the operation. On the other hand, in the method of installing the automatic opening / closing device and performing remote control, a special sensor for light, ultrasonic waves, radio waves, etc. is installed at the gate or the like, while a remote controller corresponding to these is in hand. By operating the remote controller, the sensor is made sensitive to drive the electric motor.

In these conventional automatic opening / closing devices, the receiver has to operate only by a predetermined signal. For example, in an optical sensor, sunlight,
A method is used in which the transmitter is operated by a laser beam or the like which is modulated so as not to be affected by an external light or the like. Also,
In ultrasonic and radio wave type sensors, a method of operating with a transmitter that defines a transmission frequency so as not to be confused by other similar transmitters is used.

[0004]

Therefore, as a problem in practical use of the conventional automatic opening / closing device, first, when the transmitter for remotely controlling these devices is not operated, it naturally becomes inoperable. For example, there are many occasions where the transmitter cannot be operated due to a simple failure such as exhaustion of the battery stored in the transmitter, damage due to dropping, etc., and further due to loss or defect of the transmitter. Further, since the device is highly accurate, it is expensive and has a high failure frequency. In addition, there are restrictions on the installation location of the receiver,
The reception status was unclear in some cases.

In view of such problems, the inventors of the present invention first invented an automatic opening / closing device for gates, garages, etc., which does not require a transmitter, and applied for a patent (Japanese Patent Application No. 4-108602).
However, the present invention is a further improvement of the automatic opening / closing device for gates, garages, etc. according to the previous patent application. The purpose is to provide a special transmitter necessary for the conventional automatic opening / closing device. It is an object of the present invention to provide an automatic opening / closing device for gates, garages, etc., which does not require the use of a receiver, has a clear reception status of the receiver, has a simple structure, and has a simple structure.

In FIG. 1, a light source 1-1 is, for example, an automobile headlight, a light source 1-2 is a flashlight, and a switch 2-1 is used. , The switch 2-2 is operated or the wink of the light source is blinked. The optical receivers 3-1 and 3-2 can be installed at arbitrary positions that can face the light source 1-1 or the light source 1-2, and the optical receivers 3-1 and 3-2 are photoelectric devices, respectively. 4-1 and 4-2 are integrated with the time indicators 5-1 and 5-2, the frequency indicators 6-1 and 6-2, and the optical receivers 3-1 and 3-2. Are connected in parallel with the required electronic circuits housed in the unit case 7.

Photoelectric elements 4-1 and 4-2 are photodiodes,
A photoelectric cell or the like converts light changes of incident light of the light sources 1-1 and 1-2 into electric signals, and the photoelectric devices 4-1 and 4-
2 is connected in parallel, and its output is connected to a waveform shaper 10 composed of an amplifier 8 and a comparator 9. The waveform shaper 10 makes a change in light into a pulse, which is indicated by a point P in the figure. It is an electrical waveform. The output point P of the waveform shaper 10 is connected to the inputs of the timer 11 and the preset counter 12. The timer 11 is a monostable multivibrator, and is composed of, for example, a timer IC, a capacitor C, and a time setter 13 for time adjustment using a variable resistor, and outputs an output signal indicated by a point Q in the figure. In the figure, T is the duration of the output signal, which is variably set by the time setter 13. The output of the timer 11 is connected to the input of the differentiating circuit 14, the differentiating circuit 14 sends out a pulse signal when the output of the timer 11 disappears, and is connected to one input of the delay circuit 15 and the AND gate circuit 16. There is. On the other hand, the preset counter 12 counts the pulse signal at the point P, outputs the pulse signal when it matches the number N of times set by the number of times setter 17, and is reset by the output signal of the delay circuit 15. The output of the preset counter 12 is connected to the other input of the AND gate circuit 16, and while the preset counter 12 is outputting,
When the output pulse of the differentiating circuit 14 is applied to one input of
The AND gate circuit 16 is output, and the relay circuit 18 connected to this is operated to drive the load of the electric motor 19.
On the other hand, the DC output of the power supply circuit 20 of this device and the timer 11
Is connected to a logic circuit 21 having three inputs, the output of the counter and the output of the preset counter 12, and the outputs of two circuits are output according to the sequence of the inputs. The outputs of the logic circuit 21 are the optical receivers 3-1, 3-2, respectively.
Time indicators 5-1, 5-2 and frequency indicator 6-
1 and 6-2 are connected.

More specifically, as shown in FIG. 2, the logic circuit 21 is composed of, for example, a NAND gate 22 and an OR gate 23, the input terminal S of which is the power supply circuit 20,
The input terminal C is connected to the preset counter 12, and the input terminal T is connected to each output from the timer 11. The output terminal X of the logic circuit 21 is connected to the time indicators 5-1 and 5.
-2, and the output terminal Y has the number of times indicators 6-1 and 6-
It is connected to 2. Therefore, the power supply circuit 20 is now connected to the power supply and has an output, which is input to the input terminal S, while
In a normal state where there is no output to the preset counter 12 and the timer 11, only the output terminal X outputs, and the number-of-times indicators 6-1 and 6-2 light up. When the timer 11 operates and the input terminal T receives an input, the output terminal X outputs,
The time indicators 5-1 and 5-2 turn on, at the same time, the output of the OR gate 22 becomes low level, the output of the output terminal Y disappears, and the frequency indicators 6-1 and 6-2 turn off. Next, when the output signal of the preset counter 12 is input to the input terminal C, it is output to the output terminal Y to display the number of times indicators 6-1 and 6-.
2 lights up. If the timer 11 is in the operating state at this time, the time indicators 5-1, 5-2 and the frequency indicator 6-
Both 1 and 6-2 are lit, and it is displayed that both are in a matched state.

Next, the operation will be described with reference to FIGS. 1 and 3. The timer 11 can be set by the time setting device 13, usually 2 to 5 seconds is appropriate, the preset counter 12 can be arbitrarily set by the number of times setting device 17, and the set value N is usually 3 to. Eight times is appropriate. Now, when a light change signal from the light source 1-1 or the light source 1-2 is given to the photoelectric element 2-1 or the photoelectric element 2-2, a pulse signal as shown in FIG. Is output, and the timer 11 outputs Q for a certain time T.
An output signal as shown in FIG.
1 and 5-2 are turned on (at this time, the number of times indicators 6-1 and 6
-2 goes off). The preset counter 12 counts the pulse signal at the point P, outputs it only when the set number of times N is reached, and turns on the number of times indicators 6-1 and 6-2. Timer 1
The output of 1 becomes a differential signal by the differentiating circuit 14, and when the output Q disappears, the differentiating circuit 14 outputs. When the output of the differentiating circuit 14 is input to the other of the AND gates 16 while the output of the preset counter 12 is being input, an output signal is generated and the relay circuit 18 is operated. The output of the differentiating circuit 14 resets the preset counter 12 via the delay circuit 15. Delay circuit 1
5, the output signal of the preset counter 12 is the differentiation circuit 1
For the purpose of temporally responding to the output signal of No. 4, the preferable delay time is around 0.5 seconds.

FIG. 3 shows the temporal correlation of signals in the respective parts. The horizontal axis shows time and the vertical axis shows signal values.
The pulsed electric signal is added to the signal L of the light source 1-1 or the light source 1-2 as the input signal P of the preset counter 12, and when the number-of-times setting value N matches the input signal P, the preset counter 12 is The output signal U is transmitted. If the input pulse P has a relation of P <N <P, the output signal U is not generated. The timer 11 outputs the output signal Q during the set time T and generates the output signal V of the differentiating circuit 14 when it disappears. The delay circuit 15 inputs the output signal V of the differentiating circuit 14 and resets the preset counter 12 with the output signal Z with an appropriate time delay.
In the above time correlation, the preset counter 1
When the output signal V of the differentiating circuit 14 is generated while the output signal U of 2 is being output, the output signal W is generated in the AND gate circuit 16 and the relay circuit 18 is operated. Further, the time indicators 5-1 and 5-2 are turned on during the output of the timer 11 like the output signal X of the logic circuit 21, and the frequency indicators 6-1 and 6 are provided.
Similarly, -2 lights up as shown by the output signal Y, and the coincidence points of both can be displayed and found.

As described above, the photoelectric converter of the light source 1-1 or the light source 1-2 is aimed at the number of times indicators 5-1 and 5-2 which are constantly lit by the optical receiver 3-1 or the optical receiver 3-2. Element 4-
1 or when a light change is given to the photoelectric element 4-2, first,
Since the time indicators 6-1 and 6-2 are turned on and the number of times indicators 5-1 and 5-2 are turned off at the same time, the number of light changes of the set number N is set during the set time T. 1 or the optical receiver 3-2, the frequency indicators 5-1 and 5-2 are turned on, and if the time indicators 6-1 and 6-2 are turned on, if this state is maintained. The relay circuit 18 operates.

The waveform shaper 10 does not send a signal to unchanging light such as sunlight or a street light, since it sends only a fluctuation signal of a certain constant level to a pulse, and the head of another automobile. Although the timer 11 operates for an irregular fluctuation signal such as a light, the preset counter 12 is automatically operated by the timer 11 if the optical signal does not enter the set number N times during the set time T. The relay circuit 18 does not operate because it is reset to. That is, the set time T
If the number of times N is set to an appropriate number and the operator memorizes it as a so-called keyword, the gate can be opened and closed only by the operator.

The number of times setter 1 which defines the number of times N of setting
7 and the variable resistor of the time setting device 13 that defines the set time T are installed on the back surface or inside of the case 7 so that they can be variably set, and the optical receivers 3-1 and 3-2 are weatherproof. It is preferable that the structure is installed in a place where the operator can easily see it.

In this embodiment, in order to further simplify the circuit, it is possible to use an IC in which a series of electronic circuits from the waveform shaper 10 to the AND gate circuit 16 are integrated, and the frequency indicator 5 is used. -1, 5-2, time display 6-
It is also possible to make 1 and 6-2 correspond to a two-color LED and integrate them. It is also possible to modulate the set time T and the set number of times N as a keyword into, for example, a Morse code signal, and operate the relay circuit 18 by a circuit in tune with this. On the other hand, the light sources 1-1 and 1-2 can be substituted by operating a flashlight or the like, and the relay circuit 18 also includes a sequence circuit according to the load of the electric motor 19 or the like.
