Description

Technical Field

[0001] This invention relates to the field of display system control technology, and specifically to an energy consumption optimization control method for a ship glass display system powered by photovoltaic power. Background Technology

[0002] With the advancement of information technology, single-function glass can no longer meet the needs of ship passengers. The current trend is to build integrated display systems based on multi-channel signal processing, integrating multiple functions such as advertising, entertainment, and atmosphere adjustment, and achieving a unified visual presentation on large-size glass interfaces.

[0003] Existing ship glass display systems mostly operate with constant brightness and resolution, resulting in high energy consumption, which is incompatible with the limited energy resources of photovoltaic power supply. Furthermore, they lack a dynamic adjustment mechanism based on the priority of photovoltaic power generation and display content, which can easily lead to insufficient power supply and display interruption. At the same time, existing energy consumption control methods mostly use fixed power limiting, resulting in serious energy waste.

[0004] Therefore, there is an urgent need to design a control method for photovoltaic power supply display systems that can dynamically optimize energy consumption. Summary of the Invention

[0005] To address the above technical problems, this invention provides a shipboard glass photovoltaic power supply display system and a dynamic energy consumption optimization control method to ensure display stability and improve energy utilization.

[0006] The technical solution of the present invention is: a ship glass photovoltaic power supply display system, including a control unit, and further including a display component, an energy consumption acquisition unit, a display content analysis unit, and an energy consumption optimization unit, wherein the display component, the energy consumption acquisition unit, the display content analysis unit, and the energy consumption optimization unit are all electrically connected to the control unit; The energy consumption acquisition unit is electrically connected to the photovoltaic module, the display content analysis unit is electrically connected to the display component, and the energy consumption optimization unit is electrically connected to the energy consumption acquisition unit and the display content analysis unit.

[0007] Preferably, the energy consumption acquisition unit includes a power detector and a low-power current meter.

[0008] Preferably, it also includes an ambient light monitoring component, which is electrically connected to the control unit.

[0009] A control method for a shipboard glass photovoltaic power supply display system is also provided, comprising the following steps: S1, the energy consumption acquisition unit obtains the output power of the photovoltaic module and the power of the energy storage battery in real time, and divides the power supply status into sufficient, medium and insufficient. S2, the display content analysis unit divides the display components into core content areas and non-core areas, and sets the content priority of the core content areas; S3, the energy consumption optimization unit adopts a dynamic resolution adjustment algorithm and a zoned brightness control strategy based on the power supply status and content priority; S4, the energy consumption optimization unit monitors the power supply status and display effect in real time. When the output power of the photovoltaic module is less than the preset power supply threshold, or the remaining power of the energy storage battery is less than the first preset power threshold, the display of the core content area is prioritized and the display of non-core areas is turned off.

[0010] Preferably, in step S2, the core content area is determined by an image recognition algorithm, and the content priority is divided into three levels: high priority, medium priority, and low priority. Among them, high priority corresponds to the first resolution value and the first display brightness value, medium priority corresponds to the second resolution value and the second display brightness value, and low priority corresponds to the third resolution value and the third display brightness value. First resolution value > Second resolution value > Third resolution value; The first display brightness value > the second display brightness value > the third display brightness value.

[0011] Preferably, in step S3, the dynamic resolution adjustment algorithm enables the resolution to switch adaptively within a preset resolution value range, and the partitioned brightness control strategy enables the brightness to be adjusted within a preset brightness value range.

[0012] Preferably, step S4 further includes feedback optimization: real-time monitoring and display of actual power consumption P. 实际 , and target power consumption P 目标 Compare and calculate the deviation ΔP=P 实际 -P 目标 If the deviation of ΔP exceeds the threshold, the adjustment parameters should be corrected immediately.

[0013] Preferably, step S4 further includes low light illumination replenishment: when the light intensity is less than the preset light intensity value and the remaining power of the energy storage battery is less than the second preset power threshold, the non-core area, medium priority content, and low content are forced into hibernation, and the brightness of the high priority area is reduced to the fourth display brightness value, wherein the fourth display brightness value is less than the third display brightness value.

[0014] The beneficial effects of this invention are: This system is designed specifically for ship photovoltaic power supply scenarios. Its core objective is to resolve the contradiction between the volatility of photovoltaic power supply and the energy consumption of the display system through the full-process automation of "energy status perception - content priority determination - dynamic energy consumption adjustment - feedback closed-loop optimization". At the same time, it is suitable for special environments such as strong light, turbulence and electromagnetic interference on ships.

[0015] By employing content zoning and dynamic adjustment strategies, the system's energy consumption is effectively matched to the energy supply characteristics of photovoltaic power supply; display interruptions caused by insufficient power supply are avoided, improving the stability of ship advertising display and entertainment functions, while ensuring the display effect of core content.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] A shipboard glass photovoltaic power supply display system includes a control unit, and further includes a display component, an energy consumption acquisition unit, a display content analysis unit, and an energy consumption optimization unit. The display component, energy consumption acquisition unit, display content analysis unit, and energy consumption optimization unit are all electrically connected to the control unit. The energy consumption acquisition unit is electrically connected to the photovoltaic module, the energy consumption acquisition unit display content analysis unit is electrically connected to the display component, and the energy consumption optimization unit is electrically connected to the energy consumption acquisition unit and the display content analysis unit.

[0019] In this embodiment, the energy consumption acquisition unit includes a power detector and a low-power current meter.

[0020] In this embodiment, an ambient light monitoring component is also included, and the ambient light monitoring component of the energy consumption acquisition unit is electrically connected to the control unit.

[0021] All units are connected in parallel with a 1000μF electrolytic capacitor and a 100nF ceramic capacitor. The PCB is grounded at a single point and covered with an electromagnetic shielding strip to resist electromagnetic interference from ship radar and communication equipment. The hardware model in this embodiment is: The energy consumption acquisition unit is INA219 for photovoltaic power acquisition and MAX17048 for energy storage SOC detection; The control unit is an STM32F103VET6 with a built-in content partition recognition module; The display components are flexible AMOLED and a local drive chip (SSD1351). Ambient lighting was collected using a BH1750, ranging from 1 to 65535 lux. The display brightness was collected using a TSL2561, ranging from 100-500 cd / m². See connection circuit diagram Figures 1 to 8 : A dynamic energy consumption optimization control method for a shipboard glass photovoltaic power supply display system is also provided, comprising the following steps: S1, the energy consumption acquisition unit obtains the output power of the photovoltaic module and the power of the energy storage battery in real time, and divides the power supply status into sufficient, medium and insufficient. In this embodiment: Sufficient: P ≥ P 显示 ×1.1 and SOC≥50%; Medium: P < P 显示 ×1.1 and SOC≥20%; 20%≤SOC<50% and P≥P 显示 ×0.8; Disadvantages: SOC < 20% and P < P 显示 ×0.8; S2, the display content analysis unit divides the display components into core content areas and non-core areas, and sets the content priority of the core content areas; S3, the energy consumption optimization unit adopts a dynamic resolution adjustment algorithm and a zoned brightness control strategy based on the power supply status and content priority; S4, the energy optimization unit monitors the power supply status and display effect in real time. When the output power of the photovoltaic module is less than P... 显示 If the value is ×0.6, or the remaining battery power is <20%, priority will be given to displaying core content areas, while non-core areas will be turned off.

[0022] Those skilled in the art can flexibly set different parameters.

[0023] In this embodiment, in step S2, the core content area is determined by an image recognition algorithm. The content priority is divided into three levels: high priority, medium priority, and low priority. High priority corresponds to the first resolution value and the first display brightness value, medium priority corresponds to the second resolution value and the second display brightness value, and low priority corresponds to the third resolution value and the third display brightness value. First resolution value > Second resolution value > Third resolution value; First display brightness value > Second display brightness value > Third display brightness value.

[0024] In this embodiment, the STM32 has a built-in image recognition algorithm that divides the core region and non-core region based on grayscale threshold segmentation (threshold 128); In this embodiment, in step S3, the dynamic resolution adjustment algorithm adaptively switches the resolution within a preset resolution value range, and the partitioned brightness control strategy adjusts the brightness within a preset brightness value range. See the table below: Power supply status Core area adjustment Non-core area regulation adequate 1080P resolution, 500 cd / m² brightness, 30fps frame rate 1080P resolution, 400 cd / m² brightness, 30fps frame rate medium 720P resolution, 300 cd / m² brightness, 24fps frame rate 480P resolution, 150 cd / m² brightness, 20fps frame rate insufficient 480P resolution, 200 cd / m² brightness, 15fps frame rate Pause output (sleep mode, power consumption ≤10mW) In this embodiment, step S4 also includes feedback optimization: real-time monitoring and display of actual power consumption P. 实际 , and target power consumption P 目标 Compare and calculate the deviation ΔP=P 实际 -P 目标 If the deviation of ΔP exceeds the threshold, the adjustment parameters should be corrected immediately.

[0025] The correction logic in this embodiment is as follows: ΔP > 0.5W (actual power consumption is too high): reduce the brightness of the core area by 20%, and further reduce the weight of the non-core area by 0.1; ΔP < -0.5W (power consumption too low): core area brightness increases by 10%, non-core area weight increases by 0.1 (not exceeding the corresponding state limit); Brightness feedback: When the actual brightness deviates from the target brightness by ≥50cd / ㎡, it is corrected by PWM signal.

[0026] Ship-specific scenario adaptation logic: Low light illumination power replenishment: when the light intensity is <500 lux and the remaining power of the energy storage battery is <40%, non-core areas are forced to sleep, and the brightness of the core area is reduced to 150 cd / ㎡. STM32 enters low power mode (HCLK is reduced to 36MHz). Strong turbulence stabilization (data fluctuation > 20%): Extend the data acquisition cycle to 20ms, freeze adjustment parameters for 500ms, and avoid frequent switching; Emergency Trigger (Receiving Emergency Command): Regardless of power supply status, the core area switches to full-screen red alert (highest resolution and highest brightness), while non-core areas are paused. This has the highest priority.

[0027] This system is specifically designed for shipboard photovoltaic power supply scenarios. Its core objective is to resolve the contradiction between the volatility of photovoltaic power supply and the rigidity of display system energy consumption through full-process automation of "energy status perception - content priority determination - dynamic energy consumption adjustment - feedback closed-loop optimization". It is also adapted to the special environment of ships, such as strong light, turbulence, and electromagnetic interference.

[0028] This invention is not limited to the above embodiments. Based on the technical solutions disclosed in this invention, those skilled in the art can make some substitutions and modifications to some of the technical features without creative effort, and all such substitutions and modifications are within the protection scope of this invention.
