The embodiments of the present invention will be described in detail below with reference to the drawings and embodiments, so that the application of the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.

Before describing the intelligent power control system and method thereof disclosed in the present invention, the application environment of the present invention is described. The present invention is applied to an environment having a terminal device and a controlled terminal, wherein the terminal device has wireless An electronic device capable of transmitting and transmitting to and from the controlled end; the controlled end is electrically connected to the load, and the controlled end can adjust the working task period by selecting one of a plurality of preset output modes to achieve energy saving the goal of. In actual implementation, the load may be a power consuming device of a Light Emitting Diode (LED), a fan, or the like.

The smart power control system and method thereof according to the present invention will be further described below with reference to the drawings. Please refer to FIG. 1 and FIG. 1 is a system block diagram of a smart power control system according to the present invention. The system includes: a terminal device 110 and controlled end 120. The terminal device 110 is configured to send a control message by wireless transmission. In practical implementation, the user can select a wireless transmission protocol capable of wireless transmission with the controlled terminal 120 at the terminal device 110, such as a short-range radio frequency protocol, a blue tooth protocol, and a bee colony ( ZigBee) Agreement, Global System for Mobile Communications (GSM) Agreement or Long Term Evolution (Long Term) Evolution, LTE) protocols, etc., to transfer control messages to the controlled terminal 120, even to transmit voice, text or images, and the like. In addition, the terminal device 110 has a human-machine interface, which includes displaying a plurality of operation icons, and generating corresponding control messages according to the selected operation icons, such as start, end, link, and modulation. In addition, if the terminal device 110 receives the operation message transmitted by the controlled terminal 120, the terminal device 110 can also display the operation message through the display, or even synchronize the operation message.

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, the output mode is assumed to be output according to a fixed time. The duty cycle can be defined as: D _L =[( T _F - T _NF - T _D )/ T _F ]×100%= [1-( T _NF - T _D )/ T _F ]×100%

Where T _F represents the full-load output period, T _NL represents the specified no-load output period, T _D represents the delay time of the output period, and T _{D is} mainly the error amount of the delay of the specification duty cycle, which is generated in the ideal fundamental frequency square wave. In the case of T _D =0. For example, in an ideal case, there is no output cycle delay time ( T _D =0), assuming that the output mode is full-load output, and the no-load output cycle is also 0 ( T _NL =0), therefore, the duty cycle of the full-load output is 100% ( D _L =[( T _F -0-0)/ T _F ]×100%); in addition, it is ideally assumed that the output mode is a half-load output with a duty cycle of 50% ( D _L = [( T _F - T _F /2-0) / T _F ] × 100%).

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 duty cycle can be defined as: D _L =[( f _F - f _NF - f _D )/ f _F ] ×100%

Where f _F , f _NF , and f _D sequentially represent 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 at a custom time or frequency interval. The duty cycle can be defined as: D _L = ρ ×[( T _F - T _NF - T _D )/ T _F ]×100%

Where T _D , T _F , T _{NL are} as described above, and ρ represents the weight of the adaptive adaptive task period, and its value is set to 0. ρ 1. 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 this way, the time and energy of adjusting the load output of the green energy device can be set according to the difference of the time of the sunlight and the display or display benefit.

The modulation module 124 is configured to perform modulation according to the selected output mode, so that the power supply module 121 supplies power to the load 130 in a working task period corresponding to the selected output mode. 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 is modulating different output modes through modulation. The controller is equipped with a Pulse Width Modulation (PWM) to adjust different duty cycles. 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.

In particular, in actual implementation, the system further includes a recording module 125 for continuously recording the voltage value of the photovoltaic panel conversion, the voltage value of the battery, and the current value of the load 130 at a plurality of time points as operational messages. And allowing the terminal device 110 to read the operation message for display, and the display manner thereof can be presented in the display of the terminal device 110 through a chart, and the display manner of the chart will be described later in conjunction with the drawing.

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.

In particular, after step 230, the controlled terminal 120 continuously records the voltage value of the photovoltaic panel conversion, the voltage value of the battery, and the current value of the load 130 as operational messages at a plurality of time points, and allows the terminal device to be operated. 110 reads the operational message for display (step 240). 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.

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.

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.

For example, the output mode 1 is unoptimized, and is divided into no-load (no load) and full load (full load). The battery 320 is not discharged when no load is applied, and the battery 320 is discharged at full load. Assuming that the load 130 is an LED display device, the LED is in the battery. 320 is completely dark when not discharging, and is fully bright when battery 320 is discharged; "station optimization" is used for output mode 2, and "scheduled" means fixed time interval, and the operation mode can be different. The display device is adjusted in different ways, such as: flashing the LED at different time intervals, that is, fixed flashing for 2 seconds, 8 seconds, 10 seconds, etc., and can be set to be unloaded (full dark), after 5 seconds 0% is bright for 5 seconds, then, after 5 seconds, the B% degree and D% degree are bright for 5 seconds, and finally return to no load (all dark), forming the above-mentioned cycle-based discharge operation; output The third mode is "quantitative optimization", which uses different discharge levels to adjust the load of the load 130. In practice, the load degree of the load 130 can be divided into five percentage levels, that is, A%, B. %, C%, D%, and E%, using a different percentage of the load combined with the setting of the load time length to achieve quantitative optimization, wherein the percentage of different degrees can be arbitrarily set by the user; the output mode 4 is "timing optimization" , the technology in this method In the feature, the scheduling method is used to perform different degrees of discharge to the load, and the equipment efficiency is optimized. That is to say, the scheduling discharge is given to the load, and the load load is adjusted according to different time periods of the day, and manual And the automatic timing is set in a fixed time or time period to set different fixed or quantitative optimization methods, for example, in the first time period, PM6:00 to AM2:00 is discharged with a load of A% degree, after that, Then, in the second time interval, the load is discharged at the D% level from AM2:00 to AM5:00, and then the load is discharged at the E% level from AM5:00 to PM6:00 in the third time interval. Then return to the first time of the operation mode to achieve cycle optimization.

The modulation supplies power to the load 130 in a duty cycle corresponding to 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.
