[Technical field to which the invention belongs]

[0002]

[Prior art]

 Simple and practical appliances are already inseparable from modern people's lives, and switches are used to connect power supply to various appliances, and among many types of switches, wall mounted switches And the relationship with our daily life is the closest.

[0003] Known wall-mounted switches can be roughly divided into the following several types. 1. Touch mode switch: This switch is a circulating type multi-stage control. In use, it is susceptible to static electricity and sparks from the switch contacts, causing errors in the inductive load operation. The touch mode principle is provided by the coupling capacitor. Therefore, it was relatively unsuitable for use as a switch. 2. Contact switch: This switch is directly connected to the AC power supply and can provide only a small on and off function. In use, its function is limited and cannot be used in a variable manner. Since the switch is connected to the power supply, sparks are likely to occur when the switch operates, and the contacts may melt due to overheating, and it is not ideal in terms of both moisture-proof and contact properties in use. 3. Rotary contact dimmer switch: This switch has more of a dimming function than the simple contact type switch described above, but when using it, first turn the switch to the on position and then turn the switch on. When turning off the switch, it is necessary to first adjust the brightness from the brightest state to the darkest state and then turn the switch to the off position. In use, in addition to the above-mentioned disadvantages of spark generation and lack of moisture proofness in the contact-type switch, there is a disadvantage that the operation of the brightness adjustment function is troublesome.

[0004]

[Problems to be solved by the invention]

 It is an object of the present invention to provide a kind of push-button switch control device which can adjust and memorize the load power output, which has a convenient function using a single push-button mechanical switch. In addition, sparks will not be generated at the time of switch operation, the switch control device will not be damaged by sparks, and will not cause explosion in a special environment.

[Embodiment of the invention]

 As shown in FIGS. 2 and 3, the present invention is based on a push-button switch control that controls the load 10 and a gate circuit controller 40 that is electrically connected to the push-button switch 20 and is connected in series with an AC power supply. In the apparatus, the control circuit 30 includes a reference oscillator 31, a clock timer 32, a period comparator 33, a power modulation discriminator 34, and an output driver 35. When the push button switch 20 is pressed once, one impulse signal is generated. When the push button switch 20 is continuously pressed, a square wave having a time length corresponding to the pressed time is output.

The reference oscillator 31 provides a clock signal required by the inside of the present invention.

The clock timer 32 receives the clock signal transmitted from the reference vibrator 31 and, when the impulse signal of the push button switch 20 is input, responds to the monotonous one monotonous signal. When an impulse signal is generated and the push button switch 20 is continuously pressed to output a continuous impulse signal, two or more monotonous impulse signals are generated in response.

The period comparator 33 receives the clock signal output from the above-described reference oscillator 31, and outputs a periodic square wave having a predetermined time length in response to the clock signal. The time length of the periodic square wave is set in advance. , For example, 2 seconds.

The power modulation discriminator 34 receives and discriminates the monotonous impulse signal output from the clock timer 32 and the periodic square wave output from the period comparator 33, and if the clock timer 32 When a first monotonous impulse signal is output and the period comparator 33 outputs a periodic square wave having a constant time length, the power modulation discriminator 34 outputs one high-level discriminating signal, and thereafter, outputs a high-level discriminating signal. When two or more monotonous impulse signals output from the clock timer 32 are received within one period, the power modulation identifier 34 outputs one low-level identification signal. When the time length of the transmitted square wave is larger than the periodic square wave of the period comparator 33, the power modulation discriminator 34 outputs one pulse modulation permission signal.

The output driver 35 receives the monotonous impulse signal output from the clock timer 32 described above and, when receiving the high-level identification signal from the power modulation identifier 34 described above, responds to one of the signals. When a high-level output signal is output and the low-level identification signal of the power modulation identifier 34 is received, one low-level control signal is output in response thereto, and the output driver 35 outputs the power modulation identification signal. When the pulse modulation permission signal of the device 34 is received, one power modulation impulse signal is output.

The present invention is implemented by using an ASIC at the time of implementation. The adjustment circuit 1 and the rectifying filter circuit 2 convert the AC power into a stable DC voltage and provide it to the control circuit 30, and the low-pass filter 3 controls the power frequency. The vibration circuit 4 is used as an internal vibration source, the trigger circuit 5 triggers the output of the output driver 35, the inductance L1 protects the gate circuit controller 40, and the light emitting circuit 41 controls the dimming of the push button switch 20. Instructions.

Please refer to FIG. 1 for explaining the implementation of the present invention. The load 10 is a light emitting element, and when the push button switch 20 is first pressed (at time t0), the push button switch 20 inputs one impulse to the clock timer 32 and sends it to the clock timer 32. One monotone impulse signal is generated, and at the same time, the period comparator 33 is triggered to generate one periodic square wave (edge trigger). In this embodiment, the length of the periodic square wave is set to 2 seconds (from t0 to t1), and at this time, the output state of the load 10 is turned on. When the push button switch 20 is pressed for the second time (ie, t2), there are two or more impulse inputs within the same time period square wave (ie, from t2 to t3). Turns off.

Further, the push button switch 20 is pressed and not released as it is, and the impulse signal input time provided by the push button switch 20 (ie, ft4 to t6) is equal to the time length of a predetermined periodic square wave (ie, t4 to t5). Is exceeded, the load 10 is turned on, and the load 10 is in the dimming state within the time from t5 to t6, at which time the output driver 35 outputs one power-modulated impulse signal. The power modulated impulse signal controls the power output of the load 10 by a counter (not shown) inside the output driver 35, which in this embodiment is a 128 gray scale counter, ie, Controlling the brightness of the light emitting element, when the push button switch 20 is released, the power modulated impulse signal is stored in the counter and then the low The same luminance is generated when the gate 10 is turned on. In the dimming state of the road 10, when the push button switch 20 is pressed and the output impulse signal reaches the light emitting circuit 41, the light emitting body of the light emitting circuit 41 operates according to the push button switch 20, and the light is emitted. When the button switch 20 is turned off, the illuminator of the light emitting circuit 41 emits light, and when the push button switch 20 is not pressed and released, the illuminant of the light emitting circuit 41 gradually changes from the brightest state to the darkest state. In the opposite case, the state changes from the darkest state to the brightest state, and when the push button switch 20 is turned on, the light emitting body of the light emitting circuit 41 is in the dark state. The light emitting circuit described above is composed of a capacitor C ₇ , a resistor R ₇ , and a light emitting element EL (or light emitting diode).

Further, according to the push-button switch control device of the present invention, by changing the application function of the ASIC, the operation definition of ON and OFF can be changed. For example, when the clock timer 32 has a setting line inside and the setting line signal output is “11”, the push button switch 20 is depressed, and the load 10 becomes conductive with the AC power supply. When the push button switch 20 is pressed twice or more in the cycle, the load 10 is disconnected from the AC power supply, and when the setting line signal output is “10”, the push button switch 20 is pressed down and the load 10 is released. When the push button switch 20 is pressed two or more times in the same cycle with the AC power supply disconnected, the load 10 becomes conductive with the AC power supply, and when the setting line signal output is "01", the push button switch 20 is turned on. Is pressed once, the load 10 becomes conductive with the AC power supply, and when the push button switch 20 is pressed again, the load 10 is disconnected from the AC power supply. Alternatively, when the push button switch 20 is first pressed once, the load 10 is disconnected from the AC power supply, and when the push button switch 20 is pressed again, the load 10 becomes conductive with the AC power supply, and the setting is performed. When the line signal output is "00", the push-button switch 20 determines whether the user is in a conductive state or a disconnected state by himself.

The above setting line signal output method is as shown in Table 1 below.

[Table 1]

The present invention can also be used to adjust the rotational speed of the fan, that is, the on / off control and the operation principle are the same as those described above.

That is, it has a power output storage modulation function, can modulate the power expression of the load to be used (for example, the brightness of the valve or the rotation speed of the fan), and can store the power expression after the modulation, and During the operation, the previously stored power expression can be output, eliminating the need for the user to perform the modulation step. Furthermore, no spark is generated by the DC power supply treatment, and it is extremely safe to use.
