Solar lamp control method and control system thereof

Abstract

The technical scheme of the present application discloses a control method and control system of a solar lamp, wherein the light-on mode of the lamp is set as a total light-on time of 24 hours, which is the sum of three light-on time lengths, the first light-on time length T2 of a normal power consumption, the second light-on time length T4 of a gradually changing power consumption and the third light-on time length T3 of a low power consumption.

Description

Technical Field

[0001] This invention relates to intelligent lighting systems, and more specifically to a control method and control system for an energy-saving solar lamp. Background Technology

[0002] This LED lighting control device, based on PWM control, offers flicker-free and adjustable brightness. It includes a microcontroller minimum system circuit, an LED driver circuit, and an LED switch control circuit. The microcontroller's internal program controls the duty cycle of the output PWM wave. The LED driver module adjusts the LED's output current according to the input signal duty cycle, achieving stepless brightness adjustment and flicker-free output. Simultaneously, the high and low levels of the LED switch control pins can be set via the program. The LED switch control module controls the on / off state of any LED based on the input high and low levels, further enabling independent control of the brightness and switching of any LED. It features low control cost, energy saving, flexible application, and high stability.

[0003] Currently, the solar lighting market exhibits significant differences in product functionality. Basic models often rely on simple light sensors, only capable of turning on at dusk and off at dawn, unable to adjust lighting strategies based on daylight hours, resulting in substantial energy waste during the latter half of the night. While some smart lights possess energy-saving dimming capabilities, the use of clock chips increases costs, complicates circuitry, and raises power consumption.

[0004] Patent document CN201620133484.1 discloses a solar-powered LED integrated light and a mains-powered light, both sharing a common pole. The solar-powered LED integrated light includes a solar panel, a controller, a battery pack, and LED lights. The solar panel converts solar energy into electrical energy and charges the battery pack. The controller controls the charging and discharging process of the battery pack and controls the LED lights to turn on or off. The solar-powered LED integrated light also includes a real-time clock circuit, which is electrically connected to the controller. This real-time clock circuit provides the controller with real-time time, and the controller controls the LED lights to turn on or off based on the real-time time provided by the real-time clock circuit. The real-time clock circuit can keep track of year, month, day, week, hour, minute, and second, thus the real-time time output by the real-time clock can reflect day or night. In practical implementation, the controller can control the LED lights' on / off state by controlling the power supply from the battery pack. Specifically, when the real-time clock circuit outputs a time corresponding to daytime, the controller stops the battery pack from supplying power to the LED lights, turning them off. Conversely, when the real-time clock outputs a time corresponding to nighttime, the controller supplies power to the LED lights normally, turning them on. The controller accurately determines day or night based on the real-time clock circuit, thus controlling the LED lights accordingly. This overcomes the problem of traditional solar-powered LED integrated lights sharing poles with mains lights, where the controller cannot accurately determine day or night due to mains light illumination. This allows the solar-powered LED integrated lights to operate normally even when sharing poles with mains lights. The real-time clock circuit is also connected to the battery pack, which supplies power to the real-time clock circuit. The battery pack stores energy through solar panels, and this stored energy powers both the real-time clock circuit and the LED lights.

[0005] The inventors have discovered that the above-mentioned technical solution requires the use of a real-time clock circuit (clock chip), which is not conducive to reducing the manufacturing cost of solar lamps.

[0006] Moreover, existing products generally use fixed time thresholds to control the switching of lighting modes, which cannot adapt to changes in daylight hours caused by seasonal changes, nor can they meet the differences in lighting conditions in different latitude regions.

[0007] In traditional lighting systems, morning wake-up functions often employ simple timed switches or basic light control technology. Existing technologies, such as fixed-time threshold control schemes (e.g., setting full brightness at 5:00 AM), cannot adapt to the differences in sunrise time caused by seasonal changes (e.g., the difference in sunrise time between the winter and summer solstices in the Northern Hemisphere can be more than 4 hours). Furthermore, they do not consider the influence of geographical latitude on the start time of morning light, resulting in excessively early sunrise in winter or excessively late sunrise in summer in high-latitude regions, leading to energy waste or a decline in user experience. Summary of the Invention Summary of the Invention To address the aforementioned technical problems, the objective of this invention is as follows: First, it provides a control method and system for energy-saving, environmentally friendly, and more cost-effective solar lamps, enabling clockless and low-cost high-efficiency energy-saving solar lamp control.

[0009] Secondly, a control method and control system are provided for a solar lamp that has multiple lighting modes and whose total lighting duration and the duration of each lighting mode can be automatically adjusted according to changes in daylight hours.

[0010] The technical solution of the present invention is as follows: A solar lamp control method, comprising the following steps: S1, Initialization, set the total lighting duration of the lights every 24 hours = first lighting mode duration T2 + second lighting mode duration T4 + third lighting mode duration T3; and the total lighting duration = nighttime duration = 24 - daytime duration T1; Set the solar panel charging voltage threshold N1 for daytime and N2 for nighttime. S2, collect the output voltage Y of the solar panel, and determine whether Y is greater than the daytime threshold N1. If yes, proceed to step S3; otherwise, proceed to step S5. S3, turn off the lights, and the timing module continuously accumulates the daytime duration T; S4, collect the output voltage Y of the solar panel and determine whether Y is less than the night threshold N2; if not, return to step 3; if yes, proceed to step S5. S5: Turn on the first lighting mode, stop the timing module, and assign the value of the daytime duration T recorded by the timing module at this time = daytime duration value T1; S6: Set any two of the lighting mode duration values ​​among the first lighting mode duration value T2, the second lighting mode duration value T4, and the third lighting mode duration value T3 to fixed values, and set the remaining duration value to a variable lighting mode duration value. The total lighting duration is calculated as follows: Nighttime duration = 24 - Daytime duration T1; Variable lighting mode duration = 24 - (Daytime duration T1 + any two lighting mode durations that have been set to fixed values). S7: The timing module continuously accumulates the lighting duration T of the first mode; S8: Determine whether the first mode lighting duration T is greater than or equal to the first mode lighting duration value T2; if yes, proceed to step S9; if no, proceed to step S7; S9: The timing module stops timing and turns on the third lighting mode; S10: The timing module continuously accumulates the lighting duration T of the third lighting mode; S11: Determine whether the lighting duration T of the third lighting mode is greater than or equal to the lighting duration T3 of the third lighting mode. If yes, proceed to step S12; otherwise, proceed to step S10. S12: The timing module stops timing and the second lighting mode of the lamp is activated. S13: The timing module continuously accumulates the lighting duration T of the second lighting mode; S14: Determine whether the lighting duration T of the second lighting mode is greater than or equal to the second lighting mode duration value T4. If yes, proceed to step S15; otherwise, proceed to step S13. S15; Stop timing, collect the output voltage Y of the solar panel, and determine whether Y is greater than the daytime threshold N1. If yes, proceed to step S3; otherwise, proceed to step S16. S16; The lamp continues to light up in the second lighting mode, and returns to step S15.

[0011] Furthermore, the process includes the following steps: initializing and configuring internal ports, registers, and peripherals; setting the GPIO port mode; initializing the ADC module to acquire voltage signals; configuring the timing module's operating mode and parameters; reading preset time parameters, lighting strategy data, and brightness gradient curves from the storage module; and clearing and initializing timing variables. This ensures that each hardware module is initialized for energy saving. The analog signal from the voltage detection circuit is continuously acquired by the ADC and converted into a digital signal for analysis. The duty cycle of the lighting source drive circuit is gradually increased using PWM technology to achieve a smooth increase in brightness, reaching the preset maximum brightness for morning illumination.

[0012] A solar lighting control system includes: Solar panels, made of high-conversion-efficiency monocrystalline or polycrystalline silicon, are used to convert solar energy into electrical energy to charge batteries. An overcharge protection circuit is connected to the solar panel and the battery. The solar panel is used to ensure the safe charging of the battery. Storage battery: Long-life, high-cycle-life lithium iron phosphate batteries can be used. It connects to solar panels and control circuits to store electrical energy and power various parts of the lamp.

[0013] Control circuit MCU: It adopts a low-power, high-performance microcontroller; it is used to acquire voltage detection circuit signals through ADC interface, control lighting source through GPIO interface, and realize timing function with the help of internal timing module; it integrates a storage module to store preset time parameters, lighting strategy data and brightness gradient curve.

[0014] Voltage detection circuit: It is electrically connected to the solar panel and is used to monitor the output voltage of the solar panel in real time and convert it into a digital signal for the control circuit to determine day and night.

[0015] LED light source: It is connected to the control circuit.

[0016] Preferably, the solar lighting control system further includes a PIR human body sensor.

[0017] Preferably, the solar panel is mounted on top of the lamp and the installation angle can be finely adjusted.

[0018] Preferably, the overcurrent protection circuit, the battery, and the control circuit are installed inside the lamp in a waterproof and dustproof sealed cavity, and the components are connected by tinned copper wires and insulated.

[0019] Preferably, the voltage detection circuit is installed near the solar panel and is equipped with protection and anti-interference measures.

[0020] Preferably, the solar lighting control system further includes a PWM drive circuit, which is connected to the LED light source and the control circuit.

[0021] The technical solution of this invention has the following technical effects: First, the technical solution of this invention eliminates the clock chip, simplifies the hardware design, and reduces the hardware cost by 30% - 50% while achieving the same or better technical effect. At the same time, the simpler structure reduces the difficulty of production and maintenance.

[0022] Secondly, this invention innovatively obtains daytime duration data by testing the charging voltage of solar panels. The daytime duration data T1 can automatically change according to the variation in sunshine duration. Then, the corresponding changing nighttime duration is calculated using an algorithm: 24 - T1.

[0023] Third, this invention creatively sets the lighting mode so that the total lighting duration per 24 hours is the sum of the lighting durations of three different lighting modes: a first lighting mode with normal power consumption (T2), a second lighting mode with gradually changing power consumption (T4), and a third lighting mode with low power consumption (T3). The total lighting duration is set as: total nighttime = 24 - daytime T1 = T2 + T3 + T4. Here, the daytime duration is a variable, and any two of T2, T3, and T4 are set as constants. This allows the total lighting duration and the duration of one of the lighting modes to automatically adjust with changes in daytime duration, ensuring both the effectiveness of the lighting fixture and maximizing the time spent in the low-power mode, thus achieving energy savings.

[0032] Example 2, as Figure 3 As shown, assume that the daytime duration recorded by the lamps is 14 hours.

[0033] A method for controlling a solar-powered lighting fixture includes the following steps: S1, Initialization, set the total lighting duration of the lights every 24 hours = nighttime lighting mode duration T2 + early morning lighting mode duration T4 + late night power-saving lighting mode duration T3; and the total lighting duration = nighttime duration = 24 - daytime duration T1; Set the solar panel charging voltage threshold N1 for daytime and N2 for nighttime.
