Electrical control system

The present invention relates to generating waveform control; and more particularly to an electrical control system that produces different waveforms for control.

In the indoor wiring of a general building, two wires for connecting the switch are reserved between the electrical box on the ceiling and the electrical box on the wall. When installing electrical equipment (such as lamps or fans), install the electrical equipment on the ceiling, and connect one end of the mains to the electrical equipment. The other end of the mains is connected to the switch through the reserved wires, and then back to the electrical equipment. Electrical equipment to form a power circuit. By switching the switch, the opening and closing of the electrical equipment can be controlled.

With the advancement of technology, the functions of electrical equipment are becoming more and more. Taking the LED lighting system as an example, today's LED lighting system has the function of adjusting brightness and chromaticity in addition to simple control opening and closing. Function, therefore, in addition to the original power circuit, there must be additional control lines to transmit control signals from the control panel on the wall to the LED module mounted on the ceiling.

Therefore, when a light-emitting diode lighting system having an adjustment function of brightness and chromaticity is installed, a control circuit must be additionally connected, and a control signal is transmitted through the control line to control the light-emitting diode module of the illumination system. . However, additional matching control lines will increase the cost of repair and decoration of the house.

There are two other ways to connect the control line without additional wiring. In the case of transmitting control signals, one is wireless transmission, and the other is carrier transmission. The wireless transmission method is to add a wireless receiver and a transmitter to the control panel of the LED module and the wall, and transmit the control signal to control the LED module by wireless transmission. The carrier transmission mode uses the modulator to adjust the control signal into a frequency modulation signal or an amplitude modulation signal, and uses the power line carrier to control the light emitting diode module after the demodulator is also turned into the original control signal.

However, the equipment of the foregoing two methods is expensive, and the transmitter and the transformer on the wall of the building have to be additionally connected with the power cord, and the power cord is also an additional problem. Furthermore, the signals transmitted by wireless or carrier waves are easily interfered by other wireless signals, and it is even more troublesome to pass the national EMI and EMS security regulations.

In view of this, it is an object of the present invention to provide an electrical control system that controls the load to have different actions.

To achieve the above objective, the electrical control system of the present invention is configured to control at least one load, and includes: at least one waveform control module for electrically connecting an AC power source and at least one waveform driving module. The waveform control module includes a switch. When the switch is turned on, the waveform control module outputs a raw waveform. When the switch is turned off, the waveform control module outputs a deformed waveform, wherein the positive half of the deformed waveform is The peak voltage of at least one of the negative half cycles is less than the peak voltage of the half cycle corresponding to the original waveform. The waveform driving module is electrically connected to the waveform control module, and the waveform driving module receives the electric energy output by the waveform control module, and controls the load to perform a corresponding action when the deformation waveform is generated.

The effect of the invention is that the waveform control module outputs the sine wave signal of the AC power source as the original waveform or the deformation signal, and the waveform driving module controls the load according to the deformation signal. Compared to the traditional way of controlling signals, this The invention eliminates the need for additional wiring or transmits signals by means of a wireless signal transmission device, thereby effectively reducing the cost of wiring.

In order that the present invention may be more clearly described, the preferred embodiments are illustrated in the accompanying drawings. 1 is a block diagram of an electrical control system of a first embodiment of the present invention. The electrical control system 100 includes a waveform control module 110 and a waveform driving module 120.

The waveform control module 110 is mounted on the wall surface of the building and includes a switch SW1 connected in parallel with a voltage stabilizing diode ZD1. The voltage drop of the reverse breakdown voltage of the Zener diode ZD1 reduces the peak voltage of at least one of the positive half cycle and the negative half cycle of the output power of the waveform control module 110 to form the deformation waveform. In practice, the switch SW1 can be a button switch or a switch, and in the embodiment, the switch SW1 It is a normally closed push button switch that is in an open state when the user presses. The first end of the Zener diode ZD1 is electrically connected to the AC power source S through a power switch PSW. The power switch PSW is a switch structure. The second end of the voltage stabilizing diode ZD1 is electrically connected to the waveform driving module 120. The first end of the voltage stabilizing diode ZD1 is an anode, and the second end is a cathode.

Referring to FIG. 2 at the same time, the waveform of the output of the AC power source S is a sine wave. In this embodiment, the voltage peak of the AC power source S is 155.5 volts. When the switch SW1 is turned on, the sine wave sent by the AC power source S is completely transmitted to the waveform driving module 120 via the switch SW1, so that the waveform control module 110 outputs an original waveform 140, which is the original waveform 140. A sine wave from the AC power source S.

When the switch SW1 is turned off, the waveform emitted by the AC power source S is transferred from the Zener diode ZD1 to the waveform driving module 120. When the positive half of the sine wave passes through the Zener diode ZD1, the Zener diode ZD1 is forward biased, so that there is no change in the positive half of the sine wave. When the negative half of the sine wave passes through the Zener diode ZD1, the Zener diode ZD1 is reverse biased, and therefore, before the reverse collapse voltage of the Zener diode ZD1 is reached (ie, at time t1) In the present embodiment, the reverse breakdown voltage is 5 volts, and no waveform signal is transmitted to the waveform driving module 120. When the reverse breakdown voltage of the Zener diode ZD1 is reached, the waveform of the AC power source S is transmitted to the waveform driving module 120 via the Zener diode ZD1 (ie, within time t2). Because of the voltage drop of the reverse breakdown voltage of the Zener diode ZD1, the negative half cycle of the sine wave emitted by the AC power source S and the negative half cycle waveform transmitted to the waveform drive module 120 have a voltage difference (the voltage difference is |V1-(-V2) |; -V1 is -155.5 volts, -V2 is -150.5 volts), and this voltage difference is the reverse collapse voltage of the Zener diode ZD1. Thereby, the waveform control module 110 outputs the deformation waveform 130 when the switch SW1 is turned off.

The waveform driving module 120 includes a driving circuit 122 and a Waveform detection circuit 124. The driving circuit 122 is electrically connected to the waveform control module 110 for receiving the electrical energy output by the waveform control module 110 and converting the electrical energy required for the load of the LED module 910 as an example. The LED module 910 has a plurality of LEDs for receiving electrical signals to generate illumination to provide illumination. The driving circuit 122 can controllably change the on and off states and brightness of the LED module 910. In the embodiment, the driving circuit 122 is designed based on a Pulse Width Modulation (PWM) circuit, and is adjusted to be applied to the LED module 910 by pulse width modulation. The clock width of the electrical signal. Of course, in actual implementation, the driving circuit 122 can also be designed to adjust the size of the electrical signal or other circuit for adjusting the electrical signal.

The waveform detection circuit 124 is electrically connected to the waveform control module 110. The waveform detection circuit 124 controls the LED module 910 to perform corresponding operations when the original waveform 140 and the deformation waveform 130 are generated. For example, when the waveform control module 110 outputs the original waveform 140, the waveform detecting circuit 124 outputs a maximum brightness signal to the driving circuit 122. The driving circuit 122 controls the LED module according to the maximum brightness signal. Group 910 produces maximum brightness. When the waveform control module 110 outputs the deformation waveform 130, the waveform detection circuit 124 detects the deformation waveform 130 to determine that the switch SW1 is pressed. The waveform detecting circuit 124 outputs a predetermined brightness signal, and the driving circuit 122 controls the LED module 910 to generate a brightness of a preset brightness value according to the preset brightness signal. In this embodiment, the The preset brightness value is initially set to half of the maximum brightness value. In practice, the signal outputted by the waveform detecting circuit 124 is not limited to the preset brightness signal, and may be controlled according to the time when the switch SW1 is pressed, for example, the switch. After the SW1 is continuously pressed for a predetermined time, the brightness of the LED of the LED module 910 is cyclically changed between the maximum brightness value and the minimum brightness value, and the After the switch SW1, the brightness of the light-emitting diode is fixed to the current brightness value.

The PN junction diode D2 is connected in parallel with the switch SW2, and the first end of the PN junction diode D2 is electrically connected to the AC power source S. The first end is an anode. The second end of the PN junction diode D2 is electrically connected to the waveform driving module 120, and the second end is a cathode. Referring to FIG. 4 at the same time, when the switch is turned off, the waveform control module 210 outputs a deformation waveform 230, and the original waveform 140 and the negative half-cycle waveform of the deformation waveform have a voltage difference (| -V1-(-V3) |), This voltage difference is the reverse collapse voltage of the Zener diode ZD2. In particular, when the waveform of the AC power source S is positive half cycle, the waveform and current are transmitted from the Zener diode ZD2 and the PN junction diode D2 to the waveform driving module 120, especially in the current transmission. The voltage can be simultaneously transmitted to the waveform driving module 120 by the Zener diode ZD2 and the PN junction diode D2, thereby reducing the amount of current on the Zener diode ZD2 to increase the service life, and also because of simultaneous use. The Zener diode ZD2 and the PN junction diode D2 can increase the current transmitted to the waveform driving module 120, so that the waveform driving module 120 can drive the LED module 910 with a large power consumption. .

Figure 5 is a block diagram of an electrical control system 300 in accordance with a third embodiment of the present invention. The difference between the electrical control system 300 of the third embodiment and the electrical control system 100 of the first embodiment is that the waveform control module 310 includes a switch SW2 connected in parallel with a resistor R3. The first end of the resistor R3 is electrically connected to the AC power source S through a power switch PSW. The second end of the resistor R3 is electrically connected to the waveform driving module 120.

Referring to FIG. 6 simultaneously, when the switch SW3 is turned off, the waveform generated by the AC power source S passes through the resistor R3 to form a deformation waveform 330, and the deformation waveform 330 is transmitted to the waveform driving module in the form of a sine wave. 120. The deformation waveform 330 is formed by the voltage drop of the resistor R3 causing the peak voltage of the positive half cycle and the negative half cycle of the output power of the waveform control module 310 to decrease. The peak voltage V4 of the positive half of the deformed waveform 330 is the maximum current I flowing through the resistor R3 multiplied by the resistance value (ie, V4 = I × R3), and the peak voltage of the half cycle is -V4 = -I × R3. In addition to being able to effectively change the waveform of the AC power source S into the deformation waveform 330, the deformation waveform 330 can also maintain a sine wave with an average voltage value of zero, which can facilitate the waveform driving module 120. The deformed waveform performs signal processing.

The difference between the electrical control system 400 of the fourth embodiment and the electrical control system 300 of the third embodiment is that the waveform control module 410 further includes a PN junction diode D4. The PN junction diode D4 is connected in parallel with the switch, and the first end of the PN junction diode D4 is electrically connected to the AC power source S. The first end is an anode. The second end of the PN junction diode D4 is electrically connected to the waveform driving module 120, and the second end is a cathode.

Please also refer to FIG. 8. When the switch SW4 is turned on, the sine wave signal from the AC power source S is directly transmitted to the waveform driving module 120 via the switch SW4, and the sine wave signal after the switch SW4 is the original waveform 440. . When the switch SW4 is turned off, the positive half cycle of the sine wave emitted by the AC power source S is transmitted to the waveform driving module 120 via the PN junction diode. The negative half cycle of the sine wave emitted by the AC power source S is transmitted to the waveform driving module 120 via the resistor R4. The waveform transmitted from the PN junction diode and the resistor to the waveform driving module 120 is the deformation waveform 430. Due to the design of the resistor R4, the negative half cycle of the deformed waveform 430 is smaller than the negative half cycle of the original waveform 440, and the peak voltage -V5 of the negative half cycle of the deformed waveform 430 is the maximum current I flowing through the resistor R4 multiplied by the resistance value. (ie -V5=-I×R4). The design of the fourth embodiment can effectively change the sine wave emitted by the alternating current power source S into the deformation waveform 430, and the positive half cycle of the deformation waveform 430 is connected by the PN. The surface diode is formed, so that there is no energy loss, and a larger power can be supplied to the waveform driving module 120, so that the waveform driving module 120 can drive the LED module 910 of a larger power.

In this embodiment, the waveform control module of the three first embodiment is connected in series as an example. However, in other embodiments, the waveform control module may also use the second embodiment, the third embodiment, or the fourth. The waveform control module of the embodiment or the waveform control module of the first to fourth embodiments.

Each waveform control module is the same as the waveform control module of the first embodiment, and its structure is not described herein. The first end of the switch SW51 of the first one of the waveform control modules (that is, the first waveform control module 511) is electrically connected to the AC power source S through the power switch PSW. The second end of the switch SW51 of the first waveform control module 511 is electrically connected to the first end of the switch SW52 of the waveform control module (ie, the second waveform control module 512) of the next stage. The first end of the switch SW53 of the last one of the waveform control modules (ie, the third waveform control module 513) is electrically connected to the second end of the switch SW52 of the second waveform control module.

For example, the reverse voltage of the first Zener diode ZD51 is 5 volts, and the reverse voltage of the second Zener diode ZD52 is At 7 volts, the reverse voltage of the third regulator diode ZD53 is 10 volts. When the different switches are pressed, the negative half of the deformation waveform output by the third waveform control module 511 Weeks have different peak voltages.

The deformed waveform 630 is presented as a waveform of a half-wave positive flow pattern such that the negative half cycle of the deformed waveform is zero volts. The difference between the sixth embodiment and the foregoing first to fifth embodiments is that the negative half cycle of the deformed waveform 630 of the sixth embodiment is zero volt, so that the original waveform 640 and the deformed waveform 630 have a large difference to avoid future The external environment or component aging factors cause the waveform drive module 120 to make a wrong judgment on the waveform. In addition, the switch SW6 used in the sixth embodiment is a changeover switch.

In addition, the present invention can also be applied to control the load of various electrical products such as bathroom heaters, exhaust fans, ceiling fans, and the like.

In summary, the electrical control system of the present invention uses a voltage stabilizing diode, a PN junction diode or a resistor, and a switch to convert the original waveform of the sine wave of the AC power source into a deformed waveform, and the waveform driving module The load is controlled according to the deformation waveform. Compared with the conventional method of controlling signals, the present invention can reduce the cost of wiring without adding extra wiring or transmitting signals by a wireless signal transmission device. In addition, the peak voltage of the deformed waveform is less than the peak voltage of the original waveform.
