技术领域technical field

本发明是与产生波形控制有关；特别是指一种产生不同波形以进行控制的电器控制系统。The present invention is related to the generation of waveform control; in particular, it refers to an electric control system for generating different waveforms for control.

背景技术Background technique

一般建筑物的室内配线方式，会在天花板上的电气盒与壁面上的电气盒之间预留两条供连接开关的电线。在安装电器设备(如灯具或电扇)时，将电器设备装设于天花板上，且将市电的其中一端连接于电器设备，市电的另一端通过预留的电线串接一开关，再接回该电器设备上，以形成一个电源回路。通过切换该开关，即可控制电器设备的启闭。In the general indoor wiring method of buildings, two wires for connecting switches 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 power to the electrical equipment, and connect the other end of the mains power to a switch in series through a reserved wire, and then connect back to the electrical equipment to form a power loop. By switching the switch, the opening and closing of electrical equipment can be controlled.

随着科技的进步，电器设备的功能越来越多，以发光二极管照明系统为例，现今的发光二极管照明系统除了单纯的控制启闭外，更具备有调整亮度、色度的功能，因此，除了原本的电源回路外，也必须要有额外的控制线路才能将控制信号由壁面上的控制面板传送到装设于天花板上的发光二极管模块。With the advancement of science and technology, electrical equipment has more and more functions. Taking LED lighting system as an example, today's LED lighting system has the function of adjusting brightness and chromaticity in addition to simple control of opening and closing. Therefore, In addition to the original power circuit, additional control lines are required to transmit control signals from the control panel on the wall to the LED modules installed on the ceiling.

因此，要装设具备有亮度、色度的调整功能的发光二极管照明系统时，则必须另外再配接控制线路，利用控制线路传送控制信号，以控制照明系统的发光二极管模块。然，额外配接控制线路，将会使得房屋的修缮及装潢施工成本增加。Therefore, when installing an LED lighting system with brightness and chromaticity adjustment functions, additional control lines must be connected to transmit control signals to control the LED modules of the lighting system. Of course, the additional connection of control lines will increase the repair and decoration construction costs of the house.

另有二种方式可在不额外配接控制线路的情况下传送控制信号，其一为无线传输，其二为载波传输。无线传输方式是在发光二极管模块及壁面的控制面板分别加装无线接收器与发射器，以无线传输的方式传送控制信号控制发光二极管模块。载波传输方式是利用调变器将控制信号调变成调频信号或调幅信号，利用电力线载波，再以解调器还成原来的控制信号后控制发光二极管模块。There are two other ways to transmit control signals without additional control lines, one is wireless transmission, and the other is carrier transmission. The wireless transmission method is to install a wireless receiver and a transmitter on the light emitting diode module and the control panel on the wall respectively, and transmit control signals to control the light emitting diode module through wireless transmission. The carrier transmission method is to use the modulator to modulate the control signal into a frequency modulation signal or an amplitude modulation signal, use the power line carrier, and then use the demodulator to return the original control signal to control the light-emitting diode module.

然而，前述两种方式的设备成本昂贵，且在建筑物壁面的发射器及调变器均须另外配接电源线外，配接电源线亦是额外的困扰。再者，无线或载波所传输的信号易受其它无线信号干扰，要通过各国EMI和EMS安规更是徒增困扰。However, the equipment cost of the above two methods is expensive, and the transmitter and the modulator on the wall of the building must be connected with a power line, and the power line is also troublesome. Furthermore, the signals transmitted by wireless or carrier wave are easily interfered by other wireless signals, and it is even more troublesome to pass the EMI and EMS safety regulations of various countries.

有鉴于此，本发明的目的在于提供一种电器控制系统，以控制负载有不同的动作。In view of this, the purpose of the present invention is to provide an electrical appliance control system to control loads to have different actions.

缘以达成上述目的，本发明所提供的电器控制系统，用以控制至少一负载，包括有：至少一波形控制模块，用以电性连接一交流电源以及至少一波形驱动模块。该波形控制模块包括有一开关，当该开关导通时，该波形控制模块输出一原始波形，当该开关截止时，该波形控制模块输出一变形波形，其中该变形波形的正半周与负半周的其中至少一者的峰值电压小于该原始波形相对应的半周的峰值电压。该波形驱动模块电性连接该波形控制模块，该波形驱动模块接收该波形控制模块输出的电能，且于该变形波形产生时控制该负载进行对应的动作。To achieve the above purpose, the electrical appliance control system provided by the present invention is used to control at least one load, including: at least one waveform control module, which is used to electrically connect to an AC power supply 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 an original waveform. When the switch is turned off, the waveform control module outputs a deformed waveform, wherein the positive half cycle and the negative half cycle of the deformed waveform are The peak voltage of at least one of them is smaller than the peak voltage of the corresponding half cycle of the original waveform. The waveform driving module is electrically connected to the waveform control module, the waveform driving module receives the electric energy output by the waveform control module, and controls the load to perform corresponding actions when the deformed waveform is generated.

本发明的效果在于，波形控制模块将交流电源的正弦波信号以原始波形或变形信号输出，波形驱动模块再依据变形信号控制负载。相较于传统的控制信号的方式，本发明无需增加额外的配线或是以无线信号传输装置传输信号，有效减少配线的成本。The effect of the present invention is that the waveform control module outputs the sine wave signal of the AC power supply as the original waveform or the deformed signal, and the waveform driving module controls the load according to the deformed signal. Compared with the traditional way of controlling signals, the present invention does not need to add additional wiring or use a wireless signal transmission device to transmit signals, thereby effectively reducing the cost of wiring.

具体实施方式detailed description

图1为本发明第一实施例的电器控制系统方块图。该电器控制系统100包括有一波形控制模块110以及一波形驱动模块120。FIG. 1 is a block diagram of an electrical appliance control system according to a first embodiment of the present invention. The electrical appliance control system 100 includes a waveform control module 110 and a waveform driving module 120 .

该波形控制模块110系装设于建筑物的墙面上，包括有一开关SW1并联一稳压二极管ZD1。该稳压二极管ZD1逆向崩溃电压的压降使该波形控制模块110输出电能的正半周与负半周的其中至少一者的峰值电压减少而形成该一变形波形。在实施上，该开关SW1可为按钮开关(button switch)或切换开关，而在本实施例中，该开关SW1为常闭式的按钮开关，该开关SW1在使用者按压时呈开路状态。该稳压二极管ZD1的一第一端通过一电源开关PSW电性连接该交流电源S。该电源开关PSW为切换开关结构。该稳压二极管ZD1的一第二端电性连接该波形驱动模块120。该稳压二极管ZD1的第一端为阳极，第二端为阴极。The waveform control module 110 is installed on the wall of the building, and includes a switch SW1 connected in parallel with a Zener 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 waveform control module 110 outputting electric energy to form the deformed waveform. In practice, the switch SW1 can be a button switch or a toggle switch, and in this embodiment, the switch SW1 is a normally closed button switch, and the switch SW1 is in an open state when pressed by the user. A first end of the Zener diode ZD1 is electrically connected to the AC power S through a power switch PSW. The power switch PSW is a toggle switch structure. A second end of the Zener diode ZD1 is electrically connected to the waveform driving module 120 . The first end of the Zener diode ZD1 is an anode, and the second end is a cathode.

请同时参阅图2，该交流电源S输出的波形为一正弦波，在本实施例中，该交流电源S的电压峰值为155.5伏特。当该开关SW1导通时，由交流电源S发出的正弦波，完整的经由开关SW1传送至该波形驱动模块120，使该波形控制模块110输出一原始波形140，该原始波形140即是该交流电源S发出的正弦波。Please also refer to FIG. 2 , the waveform output by the AC power supply S is a sine wave. In this embodiment, the peak voltage of the AC power supply S is 155.5 volts. When the switch SW1 is turned on, the sine wave sent by the AC power supply S is completely transmitted to the waveform driving module 120 through the switch SW1, so that the waveform control module 110 outputs an original waveform 140, which is the AC A sine wave from a power source S.

当该开关SW1截止时，由交流电源S发出的波形会改由稳压二极管ZD1传送至该波形驱动模块120。当正弦波的正半周经由该稳压二极管ZD1时，对稳压二极管ZD1为顺向偏压，因此正弦波的正半周不会有任何变化。当正弦波的负半周经由该稳压二极管ZD1时，对稳压二极管ZD1为逆向偏压，因此，在达到该稳压二极管ZD1的逆向崩溃电压前(即在时间t1内，在本实施例中逆向崩溃电压为5伏特)，不会有任何波形信号传送至该波形驱动模块120。当达到该稳压二极管ZD1的逆向崩渍电压时，该交流电源S的波形就会经由该稳压二极管ZD1而传送至该波形驱动模块120(即在时间t2内)。因为稳压二极管ZD1的逆向崩渍电压的压降影响，交流电源S所发出的正弦波的负半周与传送至波形驱动模块120的负半周波形会有一电压差(该电压差为|-V1-(-V2)|；-V1为-155.5伏特，-V2为-150.5伏特)，该电压差即为稳压二极管ZD1的逆向崩溃电压。由此，于开关SW1截止时，该波形控制模块110输出该变形波形130。When the switch SW1 is turned off, the waveform generated by the AC power source S will be transmitted to the waveform driving module 120 via the Zener diode ZD1 instead. When the positive half cycle of the sine wave passes through the zener diode ZD1, the voltage zener diode ZD1 is forward biased, so the positive half cycle of the sine wave will not have any change. When the negative half cycle of the sine wave passes through the Zener diode ZD1, the Zener diode ZD1 is reverse biased. Therefore, before reaching the reverse breakdown voltage of the Zener diode ZD1 (that is, within time t1, in this embodiment The reverse breakdown voltage is 5 volts), and no waveform signal will be sent to the waveform driving module 120 . When the reverse collapse voltage of the Zener diode ZD1 is reached, the waveform of the AC power S is transmitted to the waveform driving module 120 via the Zener diode ZD1 (ie, within time t2 ). Due to the influence of the voltage drop of the reverse collapse voltage of the Zener diode ZD1, there will be a voltage difference between the negative half cycle of the sine wave sent by the AC power supply S and the negative half cycle waveform transmitted to the waveform driving module 120 (the voltage difference is |-V1- (-V2)|; -V1 is -155.5 volts, -V2 is -150.5 volts), the voltage difference is the reverse breakdown voltage of Zener diode ZD1. Therefore, when the switch SW1 is turned off, the waveform control module 110 outputs the deformed waveform 130 .

该波形驱动模块120包括一驱动电路122及一波形侦测电路124。该驱动电路122电性连接该波形控制模块110，用以接收该波形控制模块110所输出的电能，并转换成该一以发光二极管模块910为例的负载所需的电能。该发光二极管模块910具有多个发光二极管，用以接收电信号以产生亮光提供照明。该驱动电路122是可受控制地改变该发光二极管模块910的开、关状态及亮度。于本实施例中，该驱动电路122是以脉冲宽度调变(Pulse Width Modulation，PWM)电路为基础进行设计，并通过脉冲宽度调变的方式来调整供予该发光二极管模块910的电信号的频率宽度。当然在实际实施上，该驱动电路122亦可为调整电信号大小或其他调整电信号的电路设计。The waveform driving module 120 includes a driving circuit 122 and a waveform detecting circuit 124 . The driving circuit 122 is electrically connected to the waveform control module 110 for receiving the electric energy output by the waveform control module 110 and converting it into electric energy required by the load such as the LED module 910 . The LED module 910 has a plurality of LEDs for receiving electrical signals to generate bright light for illumination. The driving circuit 122 can controlly change the on/off state and brightness of the LED module 910 . In this embodiment, the driving circuit 122 is designed based on a pulse width modulation (Pulse Width Modulation, PWM) circuit, and adjusts the electrical signal supplied to the light emitting diode module 910 by means of pulse width modulation. frequency width. Of course, in practical implementation, the driving circuit 122 can also be designed to adjust the magnitude of the electrical signal or other electrical signal adjustment circuits.

该波形侦测电路124电性连接该波形控制模块110，该波形侦测电路124且于该原始波形140及该变形波形130产生时控制该发光二极管模块910进行对应的动作。例如：当该波形控制模块110输出该原始波形140时，该波形侦测电路124输出一最大亮度信号至该驱动电路122，该驱动电路122在依据该最大亮度信号控制该发光二极管模块910产生最大亮度。当该波形控制模块110输出该变形波形130时，该波形侦测电路124侦测到该变形波形130，以判断该开关SW1受按压。而后该波形侦测电路124输出一默认亮度信号，该驱动电路122在依据该默认亮度信号控制该发光二极管模块910产生一默认亮度值的亮光，在本实施例中，该预设亮度值初始设定为最大亮度值的一半。实务上，该波形侦测电路124所输出的信号不以前述的默认亮度信号为限，亦可依据该开关SW1受按压的时间，而控制该驱动电路122进行对应的动作，例如，该开关SW1持续受按压后一预定时间后，使该发光二极管模块910的发光二极管的亮度在最大亮度值与最小亮度值之间循环变化，放开该开关SW1后，使发光二极管的亮度固定于当下的亮度值。The waveform detection circuit 124 is electrically connected to the waveform control module 110 , and the waveform detection circuit 124 controls the LED module 910 to perform corresponding actions when the original waveform 140 and the deformed waveform 130 are generated. For example: when the waveform control module 110 outputs the original waveform 140, the waveform detection circuit 124 outputs a maximum brightness signal to the driving circuit 122, and the driving circuit 122 controls the LED module 910 to generate the maximum brightness according to the maximum brightness signal. brightness. When the waveform control module 110 outputs the deformed waveform 130, the waveform detection circuit 124 detects the deformed waveform 130 to determine that the switch SW1 is pressed. Then the waveform detection circuit 124 outputs a default brightness signal, and the driving circuit 122 controls the LED module 910 to generate a default brightness value of light according to the default brightness signal. In this embodiment, the default brightness value is initially set Set to half of the maximum brightness value. In practice, the signal output by the waveform detection circuit 124 is not limited to the aforementioned default brightness signal, and the drive circuit 122 can be controlled to perform corresponding actions according to the time when the switch SW1 is pressed, for example, the switch SW1 After being continuously pressed for a predetermined time, the brightness of the LEDs of the LED module 910 is changed cyclically between the maximum brightness value and the minimum brightness value, and after the switch SW1 is released, the brightness of the LEDs is fixed at the current brightness value.

图3为本发明第二实施例的电器控制系统方块图。第二实施例的电器控制系统200与第一实施例的电器控制系统100差异在于波形控制模块210还包括一PN接面二极管D2。该PN接面二极管D2并联该开关SW2，且该PN接面二极管D2的一第一端电性连接该交流电源S，该第一端为阳极。该PN接面二极管D2的一第二端电性连接该波形驱动模块120，该第二端为阴极。请同时参阅图4，当该开关截止，该波形控制模块210会输出一变形波形230，原始波形140与变形波形负半周波形会有一电压差(|-V1-(-V3)|)，该电压差即为稳压二极管ZD2的逆向崩溃电压。其特别在于，当交流电源S发出的波形为正半周时，波形及电流会由稳压二极管ZD2及PN接面二极管D2传送至该波形驱动模块120，特别在电流的传输上，可同时通过稳压二极管ZD2及PN接面二极管D2传输至波形驱动模块120，可减少稳压二极管ZD2上的电流量，以增加使用寿命，此外因为同时使用稳压二极管ZD2及PN接面二极管D2，可增加传输至该波形驱动模块120上的电流，使该波形驱动模块120能驱动较大消耗功率的发光二极管模块910。FIG. 3 is a block diagram of an electrical appliance control system according to a second embodiment of the present invention. The difference between the appliance control system 200 of the second embodiment and the appliance control system 100 of the first embodiment is that the waveform control module 210 further includes a PN junction diode D2. The PN junction diode D2 is connected in parallel with the switch SW2, and a first end of the PN junction diode D2 is electrically connected to the AC power source S, and the first end is an anode. A second end of the PN junction diode D2 is electrically connected to the waveform driving module 120 , and the second end is a cathode. Please refer to FIG. 4 at the same time. When the switch is turned off, the waveform control module 210 will output a deformed waveform 230. There will be a voltage difference (|-V1-(-V3)|) between the original waveform 140 and the negative half-cycle waveform of the deformed waveform. The difference is the reverse breakdown voltage of Zener diode ZD2. It is particularly that when the waveform generated by the AC power source S is in the positive half cycle, the waveform and current will be transmitted to the waveform drive module 120 by the Zener diode ZD2 and the PN junction diode D2, especially in the transmission of current, it can pass through the stabilizer at the same time. The voltage diode ZD2 and the PN junction diode D2 are transmitted to the waveform driving module 120, which can reduce the current on the Zener diode ZD2 to increase the service life. In addition, because the Zener diode ZD2 and the PN junction diode D2 are used at the same time, the transmission can be increased. The current to the waveform driving module 120 enables the waveform driving module 120 to drive the light-emitting diode module 910 which consumes relatively large power.

图5为本发明第三实施例的电器控制系统300方块图。第三实施例的电器控制系统300与第一实施例的电器控制系统100差异在于，该波形控制模块310包括有一开关SW2并联一电阻R3。该电阻R3的一第一端通过电源开关PSW电性连接该交流电源S，该电阻R3的一第二端电性连接该波形驱动模块120。FIG. 5 is a block diagram of an electrical appliance control system 300 according to a third embodiment of the present invention. The difference between the appliance control system 300 of the third embodiment and the appliance 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. A first end of the resistor R3 is electrically connected to the AC power S through the power switch PSW, and a second end of the resistor R3 is electrically connected to the waveform driving module 120 .

请同时参阅图6，当该开关SW3截止时，由交流电源S发出的波形会经由电阻R3，以形成变形波形330，且该变形波形330以正弦波的形态传送至该波形驱动模块120。因电阻R3的压降使该波形控制模块310输出电能的正半周与负半周的峰值电压减少而形成该变形波形340。变形波形330的正半周的峰值电压V4为流经电阻R3的最大电流I乘于电阻值(即V4＝I×R3)，半周的峰值电压为-V4＝-I×R3。第三实施例的设计除了能有效的将交流电源S发出的波形改变成变形波形330之外，其变形波形330也还能维持平均电压值为零的正弦波，可方便波形驱动模块120对变形波形进行信号处理。Please also refer to FIG. 6 , when the switch SW3 is turned off, the waveform generated by the AC power source S passes through the resistor R3 to form a deformed waveform 330 , and the deformed waveform 330 is sent to the waveform driving module 120 in the form of a sine wave. The deformed waveform 340 is formed by reducing the peak voltage of the positive half cycle and the negative half cycle of the output power of the waveform control module 310 due to the voltage drop of the resistor R3. The peak voltage V4 of the positive half cycle 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. The design of the third embodiment can not only effectively change the waveform sent by the AC power source S into a deformed waveform 330, but also maintain a sine wave with an average voltage value of zero in the deformed waveform 330, which can facilitate the waveform driving module 120 to deform Waveforms for signal processing.

图7为本发明第四实施例的电器控制系统方块图。第四实施例的电器控制系统400与第三实施例的电器控制系统300差异在于波形控制模块410还包括一PN接面二极管D4。该PN接面二极管D4并联该开关，且该PN接面二极管D4的一第一端电性连接该交流电源S，该第一端为阳极。该PN接面二极管D4的一第二端电性连接该波形驱动模块120，该第二端为阴极。FIG. 7 is a block diagram of an electrical appliance control system according to a fourth embodiment of the present invention. The difference between the appliance control system 400 of the fourth embodiment and the appliance 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 a first end of the PN junction diode D4 is electrically connected to the AC power source S, and the first end is an anode. A second end of the PN junction diode D4 is electrically connected to the waveform driving module 120 , and the second end is a cathode.

请同时参阅图8，当该开关SW4导通时，该交流电源S发出的正弦波信号会直接经由开关SW4而传送至该波形驱动模块120，经由开关SW4后的正弦波信号即是原始波形440。当该开关SW4截止时，该交流电源S发出的正弦波的正半周会经由PN接面二极管传送至该波形驱动模块120。该交流电源S发出的正弦波的负半周，则会经由电阻R4传送至该波形驱动模块120。由PN接面二极管及该电阻而传送至该波形驱动模块120的波形即为变形波形430。因电阻R4的设计，变形波形430的负半周会小于该原始波形440的负半周，且变形波形430的负半周的峰值电压-V5为流经电阻R4的最大电流I乘于电阻值(即-V5＝-I×R4)。第四实施例的设计能有效的将交流电源S发出的正弦波改变成变形波形430之外，变形波形430的正半周是由通过PN接面二极管而形成，因此比较不会有能源的损失，可提供较大的电能给波形驱动模块120，使波形驱动模块120能驱动较大功率的发光二极管模块910。Please refer to FIG. 8 at the same time. When the switch SW4 is turned on, the sine wave signal sent by the AC power supply S will be directly transmitted to the waveform driving module 120 through the switch SW4, and the sine wave signal after passing through the switch SW4 is the original waveform 440 . When the switch SW4 is turned off, the positive half cycle of the sine wave generated by the AC power source S is transmitted to the waveform driving module 120 through the PN junction diode. The negative half cycle of the sine wave generated by the AC power source S is transmitted to the waveform driving module 120 through the resistor R4. The waveform transmitted to the waveform driving module 120 by the PN junction diode and the resistor is the deformed waveform 430 . Due to the design of the resistor R4, the negative half cycle of the deformed waveform 430 will be 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 sent by the AC power source S into the deformed waveform 430. The positive half cycle of the deformed waveform 430 is formed by passing through a PN junction diode, so there is relatively no loss of energy. Larger electric power can be provided to the waveform driving module 120 , so that the waveform driving module 120 can drive the higher power LED module 910 .

图9为本发明第五实施例的电器控制系统方块图。第五实施例的电器控制系统500与第一实施例的电器控制系统100的差异在于，该电器控制系统500包括有多个该波形控制模块，且所述波形控制模块以串连的方式电性连接于该交流电源S与该波形驱动模块120之间而共同输出该变形波形，其中各该波形控制模块的开关分别截止时，使该变形波形的正半周与负半周的其中至少一者的峰值电压各不相同。在本实施例中，以串连三个第一实施例的波形控制模块为例，但在其他实施例中，该波形控制模块也可使用第二实施例、第三实施例或第四实施例的波形控制模块或混合第一至第四实施例的波形控制模块。FIG. 9 is a block diagram of an electrical appliance control system according to a fifth embodiment of the present invention. The difference between the electrical appliance control system 500 of the fifth embodiment and the electrical appliance control system 100 of the first embodiment is that the electrical appliance control system 500 includes a plurality of the waveform control modules, and the waveform control modules are electrically connected in series. Connected between the AC power supply S and the waveform driving module 120 to jointly output the deformed waveform, wherein when the switches of each waveform control module are respectively turned off, the peak value of at least one of the positive half cycle and the negative half cycle of the deformed waveform Voltages vary. In this embodiment, three waveform control modules of the first embodiment are connected in series as an example, but in other embodiments, the waveform control module can also use the second embodiment, the third embodiment or the fourth embodiment The waveform control module or the waveform control module of the first to fourth embodiments are mixed.

每一波形控制模块与第一实施例的波形控制模块相同，其结构而不在赘述。其中，所述波形控制模块的第一者(即为第一波形控制模块511)的开关SW51的第一端通过电源开关PSW电性连接该交流电源S。该第一波形控制模块511的开关SW51的第二端电性连接下一阶的该波形控制模块(即第二波形控制模块512)的开关SW52的第一端。所述波形控制模块的最后一者(即第三波形控制模块513)的开关SW53的第一端电性连接第二波形控制模块的开关SW52的第二端。Each waveform control module is the same as the waveform control module of the first embodiment, and its structure will not be repeated here. Wherein, the first end of the switch SW51 of the first waveform control module (namely the first waveform control module 511 ) is electrically connected to the AC power source S through the power switch PSW. The second terminal of the switch SW51 of the first waveform control module 511 is electrically connected to the first terminal of the switch SW52 of the next stage waveform control module (ie, the second waveform control module 512 ). The first terminal of the switch SW53 of the last waveform control module (ie, the third waveform control module 513 ) is electrically connected to the second terminal of the switch SW52 of the second waveform control module.

所述稳压二极管的逆向崩溃电压在本实施例中都不相同，例如第一稳压二极管ZD51的逆向崩溃电压为5伏特，第二稳压二极管ZD52的逆向崩溃电压为7伏特，第三稳压二极管ZD53的逆向崩溃电压为10伏特。当按压不同开关时，第三波形控制模块511输出的变形波形的负半周具有不同的峰值电压。The reverse breakdown voltages of the Zener diodes are different in this embodiment. For example, the reverse breakdown voltage of the first Zener diode ZD51 is 5 volts, the reverse breakdown voltage of the second Zener diode ZD52 is 7 Volts, and the third Zener diode ZD52 has a reverse breakdown voltage of 7 volts. The reverse breakdown voltage of the voltage diode ZD53 is 10 volts. When pressing different switches, the negative half cycle of the deformed waveform output by the third waveform control module 511 has different peak voltages.

所述波形驱动模块120电性连接第三波形控制模块513的开关SW53的第二端，以接收由第三波形控制模块输出的原始波形或变形波形。所述波形驱动模块120分别电性连接一发光二极管模块910，用以依据该原始波形或该变形波形的不同的峰值电压而控制所电性连接的该发光二极管模块910。在本实施例中，使用三个波形控制模块，除了原始波形之外，会因为按压的开关不同而有7种不同态样的变形波形。所述波形驱动模块120可跟据不同态样的变形波形而控制发光二极管模块910有不同的动作，可灵活的操作发光二极管模块910。实务上，波形驱动模块120的数量亦可为一个、二个或三个以上，由波形驱动模块120依据变形波形的峰值电压的不同，而相应控制所连接的发光二极管模块910。上述中的第一实施例至第五实施例所输出的变形波形的正半周与负半周的峰值电压都不为零。The waveform driving module 120 is electrically connected to the second end of the switch SW53 of the third waveform control module 513 to receive the original waveform or the deformed waveform output by the third waveform control module. The waveform driving module 120 is electrically connected to an LED module 910 respectively, and is used to control the electrically connected LED module 910 according to different peak voltages of the original waveform or the deformed waveform. In this embodiment, three waveform control modules are used. In addition to the original waveform, there will be 7 different types of deformed waveforms due to different pressed switches. The waveform driving module 120 can control the LED module 910 to have different actions according to the deformed waveforms of different shapes, and can operate the LED module 910 flexibly. In practice, the number of the waveform driving module 120 can be one, two or more than three, and the waveform driving module 120 controls the connected LED modules 910 according to the peak voltage of the deformed waveform. The peak voltages of the positive half cycle and the negative half cycle of the deformed waveforms output by the first embodiment to the fifth embodiment above are not zero.

此为，本发明还包括第六实施例的电器控制系统。如图10所示，为本发明第六实施例的电器控制系统方块图。第六实施例的电器控制系统600与第一实施例的电器控制系统100差异在于，该波形控制模块610包括有一开关SW6并联一PN接面二极管D6。该PN接面二极管D6的一第一端通过电源开关PSW电性连接该交流电源S。该PN接面二极管D6的一第二端电性连接该波形驱动模块120。该PN接面二极管D6的第一端为阳极，第二端为阴极。该开关SW6在本实施例中为切换开关，实务上亦可采用按钮开关。For this reason, the present invention also includes the electrical appliance control system of the sixth embodiment. As shown in FIG. 10 , it is a block diagram of an electrical appliance control system according to a sixth embodiment of the present invention. The difference between the appliance control system 600 of the sixth embodiment and the appliance control system 100 of the first embodiment is that the waveform control module 610 includes a switch SW6 connected in parallel with a PN junction diode D6. A first end of the PN junction diode D6 is electrically connected to the AC power source S through the power switch PSW. A second end of the PN junction diode D6 is electrically connected to the waveform driving module 120 . The first end of the PN junction diode D6 is an anode, and the second end is a cathode. The switch SW6 is a toggle switch in this embodiment, but a button switch can also be used in practice.

请同时参阅图11，当该开关SW6截止时，由交流电源S发出的波形会由PN接面二极管D6传送至该波形驱动模块120。当正弦波的正半周经由该PN接面二极管D6时，对PN接面二极管D6为顺向偏压，因此正弦波的正半周不会有任何变化。当正弦波的负半周经由该PN接面二极管D6时，对PN接面二极管D6为逆向偏压，因此，正弦波的负半周并不会通过PN接面二极管D6，使变形波形630呈现为半波正流形态的波形，使该变形波形的负半周为零伏特。第六实施例与前述第一至第五实施例的差异在于，第六实施例的变形波形630的负半周为零伏特，因此原始波形640与变形波形630有较大的差异，以避免日后因外在环境或组件老化等因素，而导致波形驱动模块120对于波形的判断错误。此外第六实施例使用的开关SW6为切换开关，在使用上，使用者在按压开关SW6后，就能直接离去，不需一直待在开关附近。第五实施例的波形控制模块也能使用第六实施例的波形控制模块610。Please also refer to FIG. 11 , when the switch SW6 is turned off, the waveform generated by the AC power source S will be transmitted to the waveform driving module 120 by the PN junction diode D6 . When the positive half cycle of the sine wave passes through the PN junction diode D6, the PN junction diode D6 is forward biased, so there will be no change in the positive half cycle of the sine wave. When the negative half cycle of the sine wave passes through the PN junction diode D6, the PN junction diode D6 is reverse biased. Therefore, the negative half cycle of the sine wave does not pass through the PN junction diode D6, so that the deformed waveform 630 appears as a half Wave positive current form of the waveform, so 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 volts, so the original waveform 640 and the deformed waveform 630 have a large difference to avoid future Factors such as the external environment or component aging cause the waveform driving module 120 to make a wrong judgment on the waveform. In addition, the switch SW6 used in the sixth embodiment is a toggle switch. In use, after pressing the switch SW6, the user can leave directly without staying near the switch all the time. The waveform control module of the fifth embodiment can also use the waveform control module 610 of the sixth embodiment.

在上述中各实施例利用发光二极管模块作为负载，仅是用以说明本发明的电器控制系统，除了应用于发光二极管模块外，本发明亦可应用于其它的负载，例如马达的控制，利用波形驱动模块，以控制马达的启动、停止及转速。此外，本发明亦可应用于控制浴室暖风机、抽风机、吊扇等各类电气产品的负载。In the above-mentioned embodiments, the light-emitting diode module is used as the load, which is only used to illustrate the electrical control system of the present invention. In addition to being applied to the light-emitting diode module, the present invention can also be applied to other loads, such as motor control, using waveform The drive module is used to control the start, stop and speed of the motor. In addition, the present invention can also be applied to control loads of various electrical products such as bathroom heaters, exhaust fans, and ceiling fans.

综上所述，本发明的电器控制系统，利用稳压二极管、PN接面二极管或电阻，再配合开关，将交流电源呈正弦波的原始波形变成变形波形，波形驱动模块再依据变形波形控制负载。相较于传统的控制信号的方式，本发明无需增加额外的配线或是以无线信号传输装置传输信号，有效减少配线的成本。此外，变形波形的峰值电压相较于原始波形的峰值电压的降低很小，因此，波形驱动模块所接收的电能的能量不致衰减过多而影响负载的特性。利用稳压二极管、PN接面二极管或电阻就可达变形波形的目的，有效减少电器控制系统的制造成本。In summary, the electrical control system of the present invention uses Zener diodes, PN junction diodes or resistors, and cooperates with switches to change the original waveform of the AC power supply in the form of a sine wave into a deformed waveform, and the waveform drive module controls the waveform according to the deformed waveform. load. Compared with the traditional way of controlling signals, the present invention does not need to add additional wiring or use a wireless signal transmission device to transmit signals, thereby effectively reducing the cost of wiring. In addition, the peak voltage of the deformed waveform is slightly reduced compared with the peak voltage of the original waveform. Therefore, the energy of the electric energy received by the waveform driving module will not attenuate too much and affect the characteristics of the load. Utilizing Zener diodes, PN junction diodes or resistors can achieve the purpose of deforming waveforms, effectively reducing the manufacturing cost of electrical control systems.
