The accompanying drawings illustrate exemplary embodiments of the present invention, with like reference numerals representing like elements. It should be understood that the scales shown in the accompanying drawings are not those of the actual implementation of the present invention. These scales are for illustrative purposes only and are not drawn to scale.

[0036] Please see Figure 1 , which is a schematic diagram of the structure of a solar radiation intensity detection device provided in an embodiment of the utility model. This application provides a solar radiation intensity detection device 100. Solar radiation intensity detection device 100 is used to detect the radiation intensity value of sunlight. The specific features of each component of solar radiation intensity detection device 100 will be described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, a solar radiation intensity detection device 100 includes a solar panel 1, a sampling resistor 4, a current detection chip 2, and a control chip 3. The solar panel 1 is provided with a first output terminal 11, which converts the collected solar light into an output voltage and outputs the output voltage through the first output terminal 11. The solar panel 1 is also provided with a first ground terminal 12, which is grounded through the first ground terminal 12. Optionally, the solar panel 1 is an amorphous silicon solar panel.

[0038] In this embodiment, sampling resistor 4 is electrically connected to first output terminal 11. Sampling resistor 4 is provided with a second ground terminal 41. Sampling resistor 4 is grounded via second ground terminal 41. Specifically, detection device 100 further includes a grounding resistor 6. Grounding resistor 6 is electrically connected to second ground terminal 41, thereby grounding sampling resistor 4 via grounding resistor 6 and protecting sampling resistor 4 from damage by excessive current.

[0039] The current detection chip 2 is electrically connected to the sampling resistor 4 so that the output voltage is input to the current detection chip 2 through the sampling resistor 4 and converted into a detection current. The current detection chip 2 has a second output terminal 21 to output the detection current through the second output terminal 21.

[0040] In this embodiment, the control chip 3 is electrically connected to the second output terminal 21 to receive the detection current. The control chip 3 is provided with a calibration interface 32 and an arithmetic unit 31 communicatively connected to the calibration interface 32. The calibration interface 32 allows an external detection device 30 to be connected to the control chip 3, so that the external detection device 30 can input multiple sets of preset radiation intensity values and current values. The arithmetic unit 31 calculates a proportionality coefficient based on the multiple sets of preset radiation intensity values and current values, and calculates the current radiation intensity value based on the proportionality coefficient and the detection current. Specifically, the correspondence between the radiation intensity value and the current value can be expressed as A=K*B. Where A represents the radiation intensity value, B represents the current value, and K represents the proportionality coefficient. The arithmetic unit 31 may pre-store the above expression and determine the proportionality coefficient K based on the multiple sets of preset radiation intensity values and current values received, and calculate the current radiation intensity value based on the proportionality coefficient K and the detection current. Optionally, the control chip 3 is an MCU chip or a SOC chip. Among them, the MCU chip is a chip-level chip that can integrate peripheral interfaces such as memory, timer, USB, A / D conversion, UART, PLC, DMA, etc. The SOC chip is a system-level chip that integrates integrated circuits, communication modules, etc.

[0041] In this embodiment, the detection device 100 further includes a sampling resistor 4. The sampling resistor 4 is electrically connected to the battery panel 1 and the current detection chip 2. The output voltage is input to the current detection chip 2 via the sampling resistor 4 and converted into a detection current. The detection device 100 further includes a power supply 5. The power supply 5 is electrically connected to the current detection chip 2 and the control chip 3 to provide power to the current detection chip 2 and the control chip 3, respectively.

[0042] In this embodiment, when the proportionality coefficient calculated by the arithmetic unit 31 based on multiple sets of preset radiation intensity values and current values input from the external detection device 30 differs from the actual radiation intensity represented by sunlight, the input data from the external detection device 30 can be calibrated to improve the accuracy of the current radiation intensity value. Specifically, the arithmetic unit 31 further calculates a number of calibration values based on the multiple sets of preset radiation intensity values and current values, and then calculates the current radiation intensity value based on the detected current, the proportionality coefficient, and the calibration values.

[0043] Please see Figure 2, which is a schematic diagram of the structure of a curtain control system provided in an embodiment of the utility model. The present application also provides a curtain control system 1000. Curtain control system 1000 is used to control the contraction or extension of curtains. The present application can use curtain control system 1000 to intelligently control the contraction and extension of curtains based on sunlight, thereby intelligently providing a suitable lighting environment for indoor users. Specifically, curtain control system 1000 includes the aforementioned solar radiation intensity detection device 100. The specific features of solar radiation intensity detection device 100 have been described in detail above. Curtain control system 1000 also includes a signaling device 200 and a driving device 300. Signaling device 200 is communicatively connected to detection device 100 to receive a current radiation intensity value and, in response, output a first signal indicating that the current radiation intensity value is greater than a preset radiation intensity value, or a second signal indicating that the current radiation intensity value is less than or equal to the preset radiation intensity value. The first signal and the second signal are different signals. Signaling device 200 can quickly output different signals based on the numerical relationship between the current radiation intensity value and the preset radiation intensity value to determine whether the solar radiation intensity is excessive. The drive device 300 is connected to the curtain to control the curtain's movement between a first state (retracting the curtain) and a second state (extending the curtain). The drive device 300 is also communicatively connected to the signaling device 200 to control the curtain's movement to the second state upon receiving a first signal, or to control the curtain's movement to the first state upon receiving a second signal. This intelligently controls the curtain's movement based on the intensity of sunlight, thereby providing an optimal lighting environment for indoor users. The following details how the curtain control system 1000 controls the movement of curtains.

[0044] Please see Figure 3 and Figure 4 , Figure 3 and Figure 4 Different application scenarios of curtain control systems are illustrated respectively.

[0045] like Figure 3 and Figure 4As shown, when controlling the contraction or extension of multiple curtains 101 is required, the curtain control system 1000 can control multiple curtains 101 by increasing the number of devices within the system. Specifically, when there are two curtains 101, the curtain control system 1000 can control each curtain 101 by adding a corresponding solar radiation intensity detection device 100 to each curtain. Each curtain 101 corresponds to a solar radiation intensity detection device 100. The solar panel 1 of each solar radiation intensity detection device 100 is attached to the outdoor or indoor side of the window where the curtain 101 is located. The signal device 200 and the drive device 300 are respectively installed on the mounting structure where the curtain 101 is installed on the window. When a solar radiation intensity detection device 100 detects a current radiation intensity value, the signal device 200 receives the current radiation intensity value and correspondingly outputs a first signal or a second signal to determine whether the current radiation intensity value exceeds a preset radiation intensity value. When the signal device 200 generates a signal, the driving device 300 receives the signal and controls the curtain 101 to slide to the second state according to the first signal, or controls the curtain 101 to slide to the first state according to the second signal, thereby realizing intelligent control of the curtain 101.

[0046] In the above embodiment, the solar panels collect sunlight and convert it into an output voltage. This output voltage is then converted to a readily calculable detection current via a sampling resistor and a current detection chip. The control chip then combines the radiation intensity and current values input by an external detection device to determine the current radiation intensity corresponding to the detection current, enabling automatic detection of solar radiation intensity. Compared to expensive, specialized light detection equipment, this detection device is economical and suitable for large-scale deployment. Furthermore, it can be applied to curtain control systems, enabling curtains to automatically open or close based on light intensity, eliminating the need for manual intervention. The system also monitors light changes in real time and rapidly adjusts the curtain state to accommodate varying lighting conditions, improving user convenience. Furthermore, intelligent curtain control allows for more efficient use of natural light, reducing reliance on artificial lighting and thereby improving energy efficiency.

Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
