The controlled terminal 120 is electrically connected to the load 130. The controlled terminal 120 includes a power supply module 121, a receiving module 122, a control module 123, and a modulation module 124. The power supply module 121 is configured to provide power. For example, the application of solar energy may include components such as a photovoltaic panel (also referred to as a solar panel), an inverter, and a battery. Since the power supply module 121 is a conventional technology, it will not be repeated here.

The receiving module 122 is configured to receive a control message from the terminal device 110. In actual implementation, the receiving module 122 and the terminal device 110 use the same wireless transmission protocol to implement wireless transmission between the two.

The control module 123 is configured to select one of a plurality of output modes preset according to the control message, and the output modes are respectively pre-set with different work task periods, and the work task period may be presented in a percentage manner, for example, In square wave signals with different duty cycles, it is assumed that the output mode is output according to a fixed time, and its work task period can be defined as:

among them, Represents the full load output cycle, Represents a specified no-load output cycle, Represents the delay time of the output cycle, Mainly to correct the error amount of the delay of the work cycle, in the case of the ideal fundamental frequency square wave . For example, in an ideal situation, there is no output cycle delay time ( ), assuming the output mode is full-load output, the no-load output cycle is also 0 ( ), therefore, the duty cycle of the full load output is 100% ( In addition, in the ideal case, the output mode is assumed to be a half-load output with a duty cycle of 50% ( ).

Furthermore, in square wave signals with different duty cycles, it is assumed that the output mode is output according to a fixed frequency interval, and the work task period can be defined as:

among them, , ,versus The sequence corresponds to the full-load frequency width, the unloaded output frequency width, and the delay width of the output frequency.

In square wave signals with different duty cycles, it is assumed that the output mode is output according to a custom time or frequency interval, and its work task period can be defined as:

among them, , , As mentioned above, and It represents the weight of the adjustable adaptive task cycle, and its value is set to . In other words, the percentage of the work cycle of the output mode can be adjusted according to time or frequency, or the user can set the value of the adaptive or adaptive setting. In actual implementation, the setting of the time can be adjusted according to the appearance of the sun light 24 hours a day. For example, the output power can be given to the green energy device only at 6 o'clock in the daytime to 6 o'clock in the evening, and the rest of the time does not have to be The output of the load; in addition, if the controlled terminal 120 is a green energy device displayed or displayed in a public place, the green energy device can also be adjusted for the "display or display" benefit of the green energy device, only Load output at the time of best benefit, for example, one to achieve the "display or display" benefit, one to avoid the low time of the crowd, then display or display the green energy equipment in the public place, at 12 o'clock in the morning The output power at 5 o'clock in the morning can also be adjusted for decrement.

In practical implementation, when the controlled terminal 120 performs power supply (also referred to as discharge), a steady voltage power supply can be obtained through a voltage stabilizing circuit, and the voltage stabilizing circuit is started simultaneously with the load 130. In addition, the modulation module 124 adjusts different working task periods through a Pulse Adjustable Modulation (PWM) device through a controller that can adjust different output modes during modulation. In actual implementation, the current output of the load 130 can also be controlled by a circuit including a MOS field-effect transistor to perform "quantity (current amount)" and "time (time)" regulation.

Next, please refer to FIG. 2, which is a smart power control method of the present invention, which is applied to an architecture having a terminal device 110 and a controlled terminal 120 electrically connected to the load 130. The steps include: The terminal device 110 transmits a control message to the controlled terminal 120 by wireless transmission (step 210); the controlled terminal 120 selects one of the plurality of output modes preset according to the control message, and the output modes are respectively pre-set with different ones. The work task period (step 220); the controlled end 120 performs modulation according to the selected output mode to supply the load 130 using the work task period corresponding to the output mode (step 230). Through the above steps, the control message can be transmitted to the controlled terminal 120 through the terminal device 110, so that the controlled terminal 120 selects one of the plurality of output modes preset with different work task periods according to the control message, and according to the selected The output mode is modulated to supply the load 130 using the work task period corresponding to the output mode, and the time and energy of the load output of the green energy device can be set according to the difference of the time of the sunlight and the display benefit.

The read operation message can be implemented by using a wireless transmission mode. Since the wireless transmission mode is a conventional technology, no further description is provided herein.

The following description will be made by way of example with reference to "FIG. 3" to "FIG. 7". Please refer to "FIG. 3" and "FIG. 3" for a schematic diagram of a circuit for regulating electric energy according to the present invention. As mentioned above, the power supply module 121 is configured to provide electrical energy. In actual implementation, the power supply module 121 can perform photoelectric conversion using solar energy, and store the converted generated electrical energy to the storage battery 320 via the inverter 310, and the power supply module 121 The voltage value after the conversion of the photovoltaic panel and the voltage value of the battery 320 can also be detected through the voltmeter 330 to record the voltage values as part of the operational message if the controlled terminal 120 has the recording module 125. When the power provided by the power supply module 121 is to be regulated, the control module 123 and the modulation module 124 can be implemented by the controller 340 to select an output mode and perform modulation according to the selected output mode, and corresponding to the output mode. The working task cycle supplies power to the load 130 (eg, a light-emitting diode), and the duty cycle is a pulse width modulation signal. In this way, the output mode of the electric energy can be controlled through different pulse width modulation signals. In particular, the controller 340 can be electrically connected to the voltage stabilizing circuit 350 to obtain a stable DC power supply to the load 130 through the voltage stabilizing circuit 350 while the battery 320 is discharging.

As shown in "Fig. 4", "Fig. 4" is a schematic diagram of the energy saving effect of applying the present invention. First, the horizontal axis represents time and the vertical axis represents power consumption. The upper hollow dot is the power consumption before optimization, and the lower solid dot is the power consumption after optimization. It can be clearly seen from "Fig. 4". Before the application of the present invention for power regulation (i.e., prior to optimization), the power consumption is much longer than that after applying the power control of the present invention (i.e., after optimization). Therefore, the application of the present invention can effectively improve energy saving efficiency after power regulation.

As shown in "5A" and "5B", "5A" and "5B" are schematic flow diagrams of various output modes of the present invention. The controller 340 is configured to select one of the four output modes. For example, the output mode 1 is unoptimized, and is divided into no-load (no load) and full load (full load). When no load occurs, the battery 320 is not discharged, and when the battery is fully charged, the battery 320 is discharged. If the load 130 is an LED display device, the LED is completely dark when the battery 320 is not discharged, and is completely bright when the battery 320 is discharged; The situation is "scheduled optimization". The term "scheduled" refers to a fixed time interval. The mode of operation can be adjusted in different ways according to different display devices, such as blinking LEDs at different time intervals, ie , fixed flashing 2 seconds, 8 seconds, 10 seconds, etc., and can be set to no load (full dark), after 5 seconds to 0% to 5 seconds, then, at intervals of 5 seconds, according to the degree of B% The D% level is bright for 5 seconds, and finally returns to the no-load (full dark), forming the above-mentioned cycle-based discharge operation; the output mode 3 is "quantitative optimization", which uses different discharge levels to carry out the load 130 Load regulation, in actual implementation The load level of the load 130 is divided into five percentages, namely A%, B%, C%, D%, and E%. The quantitative optimization is achieved by using different percentages of load combined with the setting of the load time length. The percentage of different degrees can be arbitrarily set by the user; the fourth output mode is “timing optimization”. In the technical characteristics of this method, the scheduling method is used to perform different degrees of discharge to the load, and the optimization of the device efficiency is also completed. That is to say, the discharge of the schedule is given to the load, and the load load is adjusted according to different time periods of the day, and the manual and automatic time are set to be fixed or fixed in a fixed time or time period. For example, in the first time schedule, PM6:00 to AM2:00 are discharged at a load of A%, and then, in the second time interval, AM2:00 to AM5:00 are set to discharge at a load of D%. Then, in the third time schedule, AM5:00 to PM6:00 are set to discharge at a load of E%, and then, returning to the operation mode of the first time-course to achieve cycle optimization.

In practical implementation, the power supply module 121 may be composed of a battery 320, a solar panel 611, an inverter 310, and a transformer 612. Wherein, the solar panel 611 performs photoelectric conversion to generate direct current, and is converted into alternating current by the inverter 310 and stored to the battery 320, and the alternating current from the inverter 310 is converted into direct current using the transformer 612 as an electronic component using direct current. power supply. When the user wants to perform contactless control on the smart power control system, the terminal device 110 can be used to wirelessly transmit the control message to the controlled terminal 120, and the receiving module 122 of the controlled terminal 120 receives the control message, and The control module 123 selects an output mode according to the control message, so that the modulation module 124 performs modulation according to the selected output mode to supply power to the load 130 corresponding to the working task cycle of the output mode. In addition, the recording module 125 is used to continuously record the voltage value of the photovoltaic panel conversion, the voltage value of the battery, and the current value of the load 130 as operation messages at a plurality of time points. In practical implementation, the recording module 125 can be implemented using the non-volatile memory 610 and the voltmeter 613. In addition, the control module 123 can set the work task period of different output modes by using the keyboard 614 and the electronic clock 615.

As shown in Figure 7, "Figure 7" is a schematic diagram of the circuit for controlling the current output of a load with a gold-oxygen half-field effect transistor. As mentioned above, the current output of the load can be controlled by a circuit including a MOS half-effect transistor to perform "quantity" and "time" regulation. In practical implementation, the circuit connection method is as shown in "Fig. 7", wherein the source (S) of the gold-oxygen half-field effect transistor 710 is grounded, and the drain (D) is electrically connected to the positive electrode (12V) via the connection pin. The connection and the gate (G) are respectively electrically connected to one end of the 100 ohm and 2.2 k ohm resistors, wherein the other end of the 2.2 k ohm resistor is grounded; the other end of the 100 ohm resistor is electrically connected to the controller 340 via the inverter 720. connection.
