Example one
Referring to fig. 1, fig. 1 is a schematic flow chart of an energy consumption adaptive energy-saving control method for an LED display screen according to an embodiment of the present invention. The method shown in fig. 1 may be used in an LED display screen, and may also be used in a new display screen of a new technology type such as an OLED and a micro LED, which is not limited in the embodiment of the present invention. As shown in FIG. 1, the energy consumption adaptive energy-saving control method for the LED display screen can comprise the following steps:
101. and the energy consumption adjusting platform acquires the information currently sent to the display screen by the external equipment in real time.

For the display screen, the external device is not attributed to the native system of the display screen so as to be distinguished from the modules of the native system of the display screen. The energy consumption adjusting platform acquires real-time data and information currently sent to the display screen by the external equipment and completes logic calculation of the real-time data and the information according to an agreed algorithm rule; for the external equipment, the display screen is not affiliated to the external equipment, and the energy consumption adjusting platform is affiliated to the internal module of the native system of the display screen so as to be different from the external equipment.
102. The energy consumption adjusting platform carries out logic calculation on information according to a preset algorithm rule and outputs a dynamic calculation value of the display screen, wherein the information refers to information input to the display screen equipment by external equipment in real time and comprises but is not limited to real-time parameter data information, real-time state identification information, real-time notification text information, real-time character code information and dynamic graph and icon information; the preset algorithm rule refers to a rule capable of converting the information into dynamic calculation values of the display screen, aims to calculate the information into clearly identifiable and judged logic calculation quantitative results, and can realize the subsequent binding process based on the quantitative results.

Through the comparison and matching, a mapping relation is established between the dynamic calculation value of the display screen and the task state code.
103. And the energy consumption adjusting platform generates a corresponding energy-saving adjusting and controlling instruction according to the energy consumption level of the display screen and adjusts the input power of the display screen.
In the embodiment of the invention, for the LED display screen, the input power regulation and control may adopt a mode of changing a current value of an input current of the LED, and may also adopt a power PWM pulse width modulation method to realize the change of the input power, that is, periodically change a pulse width (i.e., a duty ratio) of the input power, and the display screen energy consumption regulation and control value is used to regulate the pulse width (i.e., the duty ratio) of the input power of the display screen. Since power PWM pulse width modulation is more suitable for digital control, almost all LED panels today use power PWM pulse width modulation to regulate the input power to the display panel, where processors are commonly used to provide LED power consumption regulation.
In an optional embodiment of the present invention, the energy saving regulation and control instruction includes a display screen energy consumption regulation and control value, and the display screen energy consumption regulation and control value is divided into M (M is greater than or equal to 1) levels equally or unequally according to an energy consumption proportion of the display screen. The display screen energy consumption regulating and controlling value is used for regulating the input power of the display screen.
The invention divides the running process of the external equipment into N task states, a unique task state code is preset for each task state, the task state code of the external equipment related to the dynamic calculation value of the display screen is dynamically associated with the energy consumption regulation and control of the display screen, and the energy consumption regulation and control value of the display screen dynamically follows the real-time change value of the task state code of the external equipment, thereby realizing real-time dynamic intelligent regulation and control of the energy consumption of the display screen, achieving the purposes of energy saving, consumption reduction and efficiency improvement, thoroughly improving the functional defect that the energy consumption regulation and control of the display screen is invalid due to pure timing regulation and control of the energy consumption of the display screen, completely avoiding the automatic regulation and control function failure of the energy consumption of the display screen caused by no obvious change of the environmental light intensity, reducing the visual fatigue of a viewer of the display screen, improving the working efficiency and prolonging the service life of the display screen equipment.

The external interface module of display screen is RS485 serial ports communication interface, supports Modbus RTU communication protocol, and the display screen still embeds the energy consumption and adjusts the platform.
The real-time data and information of the weighing equipment received by the display screen mainly comprise: the real-time weighing information comprises real-time weight information of the weighing vehicle, license plate information of the weighing vehicle, state information of the weighing equipment and real-time fault information of the weighing equipment. The predetermined algorithm rule refers to a rule capable of converting the received real-time data and information of the weighing device into a dynamic calculation value of the display screen, for example, if the information of the "preparation state" is input, the corresponding dynamic calculation value "a 1" of the display screen is output, and the algorithm in the process can be changed according to the actual situation or the programming thinking of a technician, so that the expected effect can be achieved, which is not limited herein. And then binding the dynamic calculation value A1 of the display screen with the corresponding task state code 1, wherein the bound task state code 1 is correspondingly associated with the preset energy consumption level 4 energy consumption of the display screen, and the power of the display screen is finally regulated to 50% because the energy consumption regulation value corresponding to the energy consumption level 4 energy consumption of the display screen is 50%.
Firstly, loading a PAFT energy-saving algorithm program module with configured initial parameters (mainly comprising dividing the operation process of a weighing device into 6 task states such as a preparation state, a proceeding state, a finishing state, a fault state, an idle state and a dormant state, presetting task state codes such as 1, 2, 3, 4, 5 and 6 for each task state, presetting task state code sequence arrangement, and presetting display screen energy consumption levels such as 50%, 75%, 12.5% and 3%) into a PAFT energy-saving algorithm program module in an energy consumption adjusting platform, and after dynamic calculation, outputting a current value of a dynamic calculation result by the PAFT energy-saving algorithm program module. The method comprises the following steps of presetting weighing equipment into six task states by using a PAFT energy-saving algorithm program module, presetting a unique task state code for each task state, and presetting a display screen energy consumption regulation and control value for each task state code, wherein the energy consumption regulation and control values corresponding to each energy level of a display screen are listed correspondingly, and the method comprises the following steps:
a preparation state: 4-level energy consumption, and the energy consumption regulation value is 50 percent
The proceeding state: 6-grade energy consumption, and the energy consumption regulation value is 75 percent
And (4) completion state: 6-grade energy consumption, and the energy consumption regulation value is 75 percent
And (3) fault state: 6-grade energy consumption, and the energy consumption regulation value is 75 percent
The idle state is 1-level energy consumption, and the energy consumption regulation value is 12.5 percent
A dormant state: the energy consumption regulation value is 3 percent when the screen is asleep
In this embodiment, the current value of the dynamic calculation result is only mapped to the energy consumption levels of 1, 4, and 6, and the energy consumption level of the display screen can be expanded according to the actual situation, it is obvious that in this embodiment, the numbers of N and M are not equal, that is, 6 task states correspond to the energy consumption control values of the display screen of 3 levels, the screen sleep level is additionally increased, and 3% energy consumption control values of the screen sleep level, which are not equal to other levels, are given, and of course, in some embodiments, N and M may be set to be equal in number.
The external interface module of the energy consumption adjusting platform acquires real-time data and information sent by the weighing equipment in real time: the external interface module receives real-time information, real-time weight and real-time information of the weighing equipment in real time;
the external interface module receives real-time data and information sent by the weighing equipment in real time, the PAFT energy-saving algorithm program module dynamically calculates the received real-time data and information, the current value of a dynamic calculation result is bound with a preset weighing equipment task state code, the task state code is correspondingly associated to a preset display screen energy consumption level, a corresponding energy-saving regulation and control instruction is generated according to the display screen energy consumption level, and the energy consumption of the display screen is regulated: when the weighing equipment detects that a vehicle enters the pound, the external interface module receives weighing preparation state information, the PAFT energy-saving algorithm program module running inside the PAFT energy-saving control module judges that the weighing equipment is in a preparation state after dynamic calculation, the energy consumption level associated with the display screen is 4 levels, and the screen display is carried out: the energy consumption regulation and control execution module regulates and controls the energy consumption of the display screen to be 4-level and the energy consumption regulation and control value to be 50 percent.
When the vehicle reaches the designated weighing position of the weighing equipment, the external interface module dynamically refreshes the received real-time weight of the vehicle, namely 28.88 tons, license plate information of Guangdong A-12345 and the weighing state information; through the comparison and matching of the weight data transmitted by the weighing equipment and the current value of the dynamic calculation result of the license plate information, the energy consumption adjusting platform judges that the weighing equipment is in a state of going on, the energy consumption level associated to the display screen is 6, and the screen displays the following data: "vehicle weight: 28.88 ton, license plate number: yue A-12345', the energy consumption execution module regulates and controls the energy consumption of the display screen to be 6 levels, and the energy consumption regulation and control value is 75%.
The weighing equipment finishes the weight data and the license plate information input of the weighing vehicle, sends real-time weight data and weighing completion state information to the external interface module of the display screen, and after dynamic calculation of a PAFT energy-saving algorithm program module in the PAFT energy-saving control module, the energy consumption adjusting platform judges that the weighing equipment is in a completion state, the energy consumption level associated with the display screen is 6 levels, and the screen displays the energy consumption level: the energy consumption execution module regulates and controls the energy consumption of the display screen to be 6-level and the energy consumption regulation and control value to be 75 percent.
When the weighing equipment detects that the vehicle is out of weight, real-time weight data and vehicle driving-away state information are sent to the external interface module, after dynamic calculation of a PAFT energy-saving algorithm program module in the PAFT energy-saving control module, the energy consumption adjusting platform judges that the weighing equipment is in an idle state, the energy consumption level associated to the display screen is 1 level, and the screen displays the energy consumption: the energy consumption execution module regulates and controls the energy consumption of the display screen to be 1 level and the energy consumption regulation and control value to be 12.5 percent.
At any time, as long as the fault state information sent by the weighing equipment is received, after dynamic calculation by a PAFT energy-saving algorithm program module in the PAFT energy-saving control module, the energy consumption adjusting platform judges that the weighing equipment is in the fault state, the energy consumption level associated with the display screen is 6, and the screen flickers to display the current fault information, for example: the weighing sensor is in fault and requires timely maintenance, the energy consumption execution module regulates and controls the energy consumption of the display screen to be 6-level, and the energy consumption regulation and control value is 75%.
The data or information received by the external interface module does not exceed the preset deviation range within 30 minutes continuously, after dynamic calculation of a PAFT energy-saving algorithm program module in the PAFT energy-saving control module, the energy consumption adjusting platform judges that the weighing equipment is in a dormant state, the energy consumption level associated with the display screen is 1 level, the screen is off and standby, the energy consumption executing module adjusts and controls the energy consumption of the display screen to be 1 level, and the energy consumption adjusting and controlling value is 12.5%.
In a word, the external interface module receives real-time data and information of the weighing equipment in real time, the PAFT energy-saving algorithm program module running in the PAFT energy-saving control module synchronously refreshes the current value of the dynamic calculation result, and the display screen dynamically regulates and controls the energy consumption level of the display screen according to the current task state of the associated weighing equipment through comparison and matching; and meanwhile, the display screen also dynamically updates the current display content of the screen. The energy consumption regulation and control process satisfactorily overcomes the functional defect of a method for regulating and controlling energy consumption only by timing, and simultaneously thoroughly makes up for the control vulnerability that the function of automatically regulating and controlling energy consumption is completely invalid by adopting the change value of the light intensity of the environment when the light intensity of the environment where the display screen is located has no obvious change, thereby finally achieving the purposes of saving energy, reducing consumption and improving efficiency of the display screen.
According to the above-mentioned weighing equipment idle state accounts for 40% in whole task state, the ready state accounts for 5% in whole task state, and the dormancy state accounts for 2% as the basis of calculating, then the energy-saving display screen of energy consumption is regulated and control according to task state intelligence that this application provided compares with the display screen energy consumption that weighing equipment whole task state in-process all was 8 grades of energy consumption: the energy consumption can be reduced by more than 55%, the service life of the display screen can be prolonged by 25%, meanwhile, the energy consumption of the display screen is dynamically and suitably changed in different task states, the screen brightness of the display screen is correspondingly and dynamically and adaptively adjusted, so that a driver of a vehicle entering the pound can pay more attention to key information, and visual fatigue is avoided.
