[0036] The embodiment of the present invention discloses a multi-level judgment method and judgment system for light intensity, which can realize multi-level judgment on light intensity to more accurately control the lifting and lowering of an automatic clothes drying machine.

[0037] The following is a detailed description with reference to the accompanying drawings.

[0038] Embodiment 1

[0039] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of a multi-level determination method of light intensity disclosed in an embodiment of the present invention. Figure 1 As shown, the multi-level determination method of light intensity may include the following steps.

[0040] 101. The judgment system uses an equivalent resistance calculation formula to substitute the photosensitive sampling voltage value, the power supply sampling voltage value and the photosensitive peripheral resistance value to calculate the photosensitive equivalent resistance value affected by the power supply voltage.

[0041] As an optional implementation, in an embodiment of the present invention, the system may first obtain three key values: a photosensitive sampling voltage value (a voltage generated by a photosensitive element, reflecting light intensity), a power sampling voltage value (a voltage value of a system power supply), and a photosensitive peripheral resistance value (a resistance value connected in series or in parallel with a photosensitive element). Subsequently, the equivalent resistance calculation formula may be used to substitute these values ​​to calculate the photosensitive equivalent resistance value affected by the power supply voltage. The equivalent resistance value may reflect the total resistance of the photosensitive element and the peripheral resistance combined under the current power supply voltage and light conditions.

[0042] As an optional implementation, in an embodiment of the present invention, the fluctuation of the power supply voltage will directly affect the working state of the photosensitive element, thereby affecting the measurement of light intensity. By calculating the equivalent resistance value, the performance of the photosensitive element under the current power supply voltage can be more accurately reflected, providing a reliable basis for subsequent light intensity judgment. The present application can accurately calculate the photosensitive equivalent resistance value affected by the power supply voltage by substituting the photosensitive sampling voltage value, the power supply sampling voltage value and the photosensitive peripheral resistance value into the equivalent resistance calculation formula. This helps to eliminate the influence of power supply voltage fluctuations on the performance of the photosensitive element and improve the accuracy of light intensity measurement.

[0043] As an optional implementation, in the embodiment of the present invention, the present application can more accurately calculate the photosensitive equivalent resistance value affected by the power supply voltage by comprehensively considering the photosensitive sampling voltage, the power supply sampling voltage and the photosensitive peripheral resistance, using the equivalent resistance calculation formula. This helps to eliminate the influence of power supply voltage fluctuations on the performance of the photosensitive element, thereby improving the accuracy of light intensity measurement.

[0044] 102. The judgment system substitutes the photosensitive equivalent resistance value, the power supply sampling voltage value and the photosensitive peripheral resistance value into the light intensity threshold calculation formula to calculate the first light intensity judgment threshold.

[0045] As an optional implementation, in the embodiment of the present invention, the present application uses the calculated photosensitive equivalent resistance value, the power supply sampling voltage value and the photosensitive peripheral resistance value to dynamically calculate the first light intensity judgment threshold value, so as to more accurately judge whether the current light intensity reaches or exceeds a certain level. This helps the system to automatically adjust the judgment standard according to the current ambient light conditions and power supply voltage status, thereby improving the adaptability and flexibility of the system.

[0046] 103. After determining the theoretical photosensor voltage value according to the power supply sampling voltage value, the judgment system substitutes the theoretical photosensor voltage value, the power supply sampling voltage value and the photosensitive peripheral resistance value into the equivalent resistance calculation formula to calculate the theoretical photosensor equivalent resistance value.

[0047] As an optional implementation, in the embodiment of the present invention, under ideal conditions, the performance of the photosensitive element is known, and the theoretical photosensitive voltage value and the theoretical equivalent resistance value can be obtained through theoretical calculation. These values ​​can be used as a benchmark for actual measurement to evaluate whether the performance of the photosensitive element meets the design requirements, and help evaluate the performance deviation of the actual photosensitive element, so that the system maintains stable performance when the light intensity changes, thereby enhancing the stability and reliability of the system.

[0048] 104. The judgment system substitutes the photosensitivity theoretical equivalent resistance value, the power supply sampling voltage value and the photosensitivity peripheral resistance value into the light intensity threshold calculation formula to calculate the second light intensity judgment threshold.

[0049] As an optional implementation, in an embodiment of the present invention, in actual application, the light intensity needs to be judged between multiple thresholds. By calculating the second light intensity judgment threshold, the system can more finely divide the light intensity level to meet the needs of different application scenarios. This helps the system to further refine the light intensity judgment standard and improve the accuracy and reliability of the judgment.

[0050] 105. The judgment system judges the light-sensitive sampling voltage value with the first light intensity judgment threshold and the second light intensity judgment threshold respectively to determine the current light intensity level.

[0051] As an optional implementation, in the embodiment of the present invention, the determination of the light intensity level is the basis for the system to realize the automatic control or alarm function. By comparing the light-sensitive sampling voltage value with the determination threshold, the system can accurately determine the current light intensity level and take corresponding measures to deal with different lighting conditions. This helps the system to take corresponding control measures or send corresponding alarm signals according to the light intensity level.

[0052] As an optional implementation, in an embodiment of the present invention, the present application can dynamically set the threshold of photosensitive sampling, that is, the threshold voltage of the point is calculated to obtain the threshold equivalent resistance through a specified equivalent resistance calculation formula. Under different power supply voltages, the threshold equivalent resistance always remains fixed. When the power supply voltage changes, the present application needs to re-submit the threshold equivalent resistance into the calculation to obtain the threshold voltage after the power supply voltage changes, thereby realizing the function of setting a dynamic threshold.

[0053] As an optional implementation, in the embodiment of the present invention, the system can calculate the equivalent resistance and the light intensity judgment threshold by measuring the voltage of the photosensitive element and the known resistance value. Then, according to the comparison result of the sampled voltage and the judgment threshold, the current light intensity level is determined, and this information is sent to the elevator equipment to control its lifting, thereby realizing the requirements of accurate measurement, level division, automatic control, safety and energy saving of light intensity. In addition, the system also takes into account the changes in human body signals and light intensity to make corresponding operational adjustments.

[0054] exist Figure 1 In the multi-level judgment method of light intensity, the judgment system is used as an example to describe it. It should be noted that Figure 1 The execution subject of the multi-level judgment method of light intensity may also be an independent device associated with the judgment system, which is not limited in the embodiment of the present invention.

[0055] It can be seen that the implementation Figure 1 The described multi-level judgment method of light intensity can realize multi-level judgment of light intensity to more accurately control the raising and lowering of the automatic clothes drying machine.

[0056] In addition, implementation Figure 1 The multi-level judgment method of light intensity described can eliminate the influence of power supply voltage fluctuation on the performance of photosensors, thereby improving the accuracy of light intensity measurement.

[0057] Embodiment 2

[0058] See also Figure 2 , Figure 2 FIG. 1 is a flow chart of another multi-level determination method of light intensity disclosed in an embodiment of the present invention. Figure 2 The multi-level determination method of light intensity may include the following steps:

[0059] 201. Determine system utilization Calculate the photosensitive equivalent resistance value.

[0060] 202. Determine system utilization A first light intensity judgment threshold is calculated.

[0061] 203. Determine system utilization Calculate the theoretical equivalent resistance of the photosensor.

[0062] As an optional implementation, in an embodiment of the present invention, the resistance value of the photosensitive element changes with the light intensity. By measuring the sampled voltage and combining it with the known resistance value, the equivalent resistance of the photosensitive element can be calculated, thereby indirectly obtaining the light intensity information. The calculation of the theoretical equivalent resistance takes into account the ideal characteristics of the photosensitive element, which helps to calibrate and verify the accuracy of the actual measurement results. By accurately calculating the equivalent resistance of the photosensitive element, the present application can more accurately reflect the changes in the ambient light intensity and improve the sensitivity and accuracy of the system.

[0063] 204. Determine system utilization A second light intensity judgment threshold is calculated.

[0064] 205. After determining the theoretical hysteresis voltage value based on the power supply sampling voltage value, determine the system utilization Calculate the theoretical hysteresis equivalent resistance value.

[0065] 206. Determine system utilization Calculate the hysteresis judgment threshold voltage value.

[0066] As an optional implementation, in an embodiment of the present invention, the setting of the light intensity judgment threshold is based on the characteristics of the photosensitive element and the actual application requirements, ensuring that the system can work normally under different lighting conditions. The setting of the hysteresis judgment threshold voltage is to increase the stability and reliability of the system and prevent frequent misjudgments and operations caused by slight changes in light intensity. The present application can automatically judge the current light intensity level and take corresponding operations as needed by setting the light intensity judgment threshold. At the same time, the introduction of the hysteresis judgment threshold voltage increases the system's tolerance to changes in light intensity and avoids misoperation caused by slight fluctuations.

[0067] 207. The judgment system subtracts the hysteresis judgment threshold voltage value from the first light intensity judgment threshold value to calculate a minimum value of the first light intensity hysteresis judgment threshold range.

[0068] 208. The judgment system determines a first illumination intensity hysteresis judgment threshold range; wherein a maximum value of the first illumination intensity hysteresis judgment threshold range is the first illumination intensity judgment threshold.

[0069] 209. The judgment system subtracts the hysteresis judgment threshold voltage value from the second light intensity judgment threshold value to calculate a minimum value of the second light intensity hysteresis judgment threshold range.

[0070] 210. The judgment system determines a second illumination intensity hysteresis judgment threshold range; wherein a maximum value of the second illumination intensity hysteresis judgment threshold range is a second illumination intensity judgment threshold.

[0071] As an optional implementation, in an embodiment of the present invention, the light intensity may fluctuate in actual applications. By setting the hysteresis judgment threshold range, the system can tolerate such fluctuations within a certain range, thereby avoiding frequent misjudgments and operations. At the same time, the system can also handle changes in light intensity more flexibly, thereby improving the adaptability and robustness of the system.

[0072] 211. The judgment system judges the light-sensitive sampling voltage value with the first light intensity judgment threshold and the second light intensity judgment threshold respectively to determine the current light intensity level.

[0073] 212. The judgment system sends the current light intensity level to the associated elevator device according to the specified coding logic communication, so that the elevator device is lifted or lowered to the specified position according to the current light intensity level; wherein the specified coding logic includes system identity information and a key value containing the current light intensity level.

[0074] As an optional implementation, in an embodiment of the present invention, the control of the elevator equipment of the present application is based on the current light intensity level and system identity information, which can ensure the accuracy and safety of the control.

[0075] 213. If a human body signal is detected within a certain period of time, the system will start human sensing related operations; among which, human sensing related operations include shutting down disinfection and voice recognition functions.

[0076] 214. If the current light intensity judgment result is a no light state, the system is judged to start the lighting function and end this process.

[0077] As an optional implementation, in an embodiment of the present invention, when a human body signal is detected, the system can automatically start human-sensing related operations, such as turning off disinfection and voice recognition functions, thereby avoiding unnecessary operations when people are present, improving the system's security and user experience. At the same time, the present application can also automatically provide lighting in a dark state to meet actual application needs.

[0078] See also Figure 3 , Figure 3 1 is a flow chart of judging the light-sensitive sampling voltage value with the first light intensity judgment threshold and the second light intensity judgment threshold respectively according to the embodiment of the present invention. Figure 3 , the method may include the following steps:

[0079] 301. When the first illumination intensity judgment threshold is greater than the second illumination intensity judgment threshold, if the photosensitivity sampling voltage value is greater than the first illumination intensity judgment threshold, the judgment system determines that the current illumination intensity level is a strong light level.

[0080] As an optional implementation, in an embodiment of the present invention, the present application can divide the light intensity into three states: strong light, medium light, and weak light. When the sampled voltage is higher than the strong light threshold, it is determined to be a strong light state; when it is lower than the weak light threshold, it is determined to be a weak light state; and when it is between the strong light threshold and the weak light threshold, it is determined to be a medium light state. Figure 7 and Figure 8 shown.

[0081] 302. If the photosensitivity sampling voltage value is between the first light intensity judgment threshold and the second light intensity judgment threshold, but not within the first light intensity hysteresis judgment threshold range, the judgment system determines that the current light intensity level is a medium light level; wherein the first light intensity hysteresis judgment threshold range is between the first light intensity judgment threshold and the second light intensity judgment threshold.

[0082] 303. If the photosensitivity sampling voltage value is less than the second light intensity judgment threshold value, but is not within the second light intensity hysteresis judgment threshold range, the judgment system determines that the current light intensity level is a low light level; wherein the maximum value of the second light intensity hysteresis judgment threshold range is less than the second light intensity judgment threshold value.

[0083] 304. When the photosensor sampling voltage value is within the first light intensity hysteresis judgment threshold range, if the previous light intensity level is a medium light level, the judgment system determines that the current light intensity is entering a strong light state, and determines that the current light intensity level is a strong light level.

[0084] As an optional implementation, in an embodiment of the present invention, based on actual sampling data analysis, when sunlight shines directly on the front of the remote control, the sampled voltage is at a relatively large value and changes very little regardless of morning, noon or night. However, in cloudy or rainy weather, depending on the placement of the remote control, the sampled voltage increases from 0mV and has a relatively large floating range. Therefore, the hysteresis of the set strong light threshold will be smaller, while the hysteresis of the set weak light threshold will be relatively larger.

[0085] In the embodiment of the present invention, Figure 7 and Figure 8 As shown in the figure, when the light-sensitive sampling voltage value is within a certain light intensity hysteresis judgment threshold range, the system will also consider the previous light intensity level to judge the change trend of the current light intensity. Among them, all the set thresholds need to be calculated through the power supply sampling voltage value and the set threshold resistance, and are not fixed values.

[0086] As an optional implementation, in an embodiment of the present invention, when the first light intensity judgment threshold is greater than the second light intensity judgment threshold, and the photosensitivity sampling voltage value is within the first light intensity hysteresis judgment threshold range, if the previous light intensity level is a strong light level, it is judged that the current light intensity is entering a medium light state, so as to determine that the current light intensity level is a medium light level; if the previous light intensity level is a medium light level, it is judged that the current light intensity is entering a strong light state, so as to determine that the current light intensity level is a strong light level.

[0087] As an optional implementation, in an embodiment of the present invention, when the first light intensity judgment threshold is greater than the second light intensity judgment threshold, and the photosensitivity sampling voltage value is within the second light intensity hysteresis judgment threshold range, if the previous light intensity level is a medium light level, it is judged that the current light intensity is entering a low light state, so as to determine that the current light intensity level is a low light level; if the previous light intensity level is a low light level, it is judged that the current light intensity is entering a medium light state, so as to determine that the current light intensity level is a medium light level.

[0088] 305. When the photosensor sampling voltage value is within the second light intensity hysteresis judgment threshold range, if the previous light intensity level is a low light level, the judgment system determines that the current light intensity is entering a medium light state, so as to determine that the current light intensity level is a medium light level.

[0089] 306. When the first illumination intensity judgment threshold is less than the second illumination intensity judgment threshold, if the photosensitivity sampling voltage value is greater than the second illumination intensity judgment threshold, the judgment system determines that the current illumination intensity level is a strong light level.

[0090] 307. If the photosensitivity sampling voltage value is between the first light intensity judgment threshold and the second light intensity judgment threshold, but not within the second light intensity hysteresis judgment threshold range, the judgment system determines that the current light intensity level is a medium light level; wherein the second light intensity hysteresis judgment threshold range is between the first light intensity judgment threshold and the second light intensity judgment threshold.

[0091] 308. If the photosensitivity sampling voltage value is less than the first light intensity judgment threshold value, but is not within the first light intensity hysteresis judgment threshold range, the judgment system determines that the current light intensity level is a low light level; wherein the maximum value of the first light intensity hysteresis judgment threshold range is less than the first light intensity judgment threshold value.

[0092] 309. When the photosensor sampling voltage value is within the second light intensity hysteresis judgment threshold range, if the previous light intensity level is a medium light level, the judgment system determines that the current light intensity is entering a strong light state, and determines that the current light intensity level is a strong light level.

[0093] 310. When the photosensor sampling voltage value is within the first light intensity hysteresis judgment threshold range, if the previous light intensity level is a low light level, the judgment system determines that the current light intensity is entering a medium light state, so as to determine that the current light intensity level is a medium light level.

[0094] As an optional implementation, in an embodiment of the present invention, when the first light intensity judgment threshold is less than the second light intensity judgment threshold, and the photosensitivity sampling voltage value is within the second light intensity hysteresis judgment threshold range, if the previous light intensity level is a strong light level, it is judged that the current light intensity is entering a medium light state, so as to determine that the current light intensity level is a medium light level; if the previous light intensity level is a medium light level, it is judged that the current light intensity is entering a strong light state, so as to determine that the current light intensity level is a strong light level.

[0095] As an optional implementation, in an embodiment of the present invention, when the first light intensity judgment threshold is less than the second light intensity judgment threshold, and the photosensitivity sampling voltage value is within the second light intensity hysteresis judgment threshold range, if the previous light intensity level is a medium light level, it is judged that the current light intensity is entering a low light state, so as to determine that the current light intensity level is a low light level; if the previous light intensity level is a low light level, it is judged that the current light intensity is entering a medium light state, so as to determine that the current light intensity level is a medium light level.

[0096] As an optional implementation, in the embodiment of the present invention, the system can determine the current light intensity level by comparing the photosensitive sampling voltage value and the preset light intensity judgment threshold. When the photosensitive sampling voltage value is between the two judgment thresholds, the system will also consider the corresponding hysteresis judgment threshold range and the previous light intensity level to judge the change trend of the current light intensity. This design can make the system more sensitive to changes in light intensity and can more accurately reflect the actual situation of light intensity.

[0097] As an optional implementation, in an embodiment of the present invention, for projects where the battery power supply voltage may change, the method for setting the photosensitivity threshold may refer to the method of the present application to calculate the dynamic threshold; and for projects with a stable power supply, there is no need to consider the impact of the power supply voltage on the photosensitivity threshold, and the threshold may be directly set to a fixed value. For example, for a system with a DC power supply of 5V or 3.3V, it is only necessary to calculate the threshold voltage corresponding to the power supply voltage using the above-mentioned calculated threshold resistance, and then fine-tune it according to the actual project.

[0098] As an optional implementation, in the embodiment of the present invention, the present application can divide the light intensity level more finely and reduce misjudgment by setting multiple judgment thresholds (first light intensity judgment threshold, second light intensity judgment threshold) and hysteresis judgment threshold range. And the present application is applicable to changes in different lighting environments, which enhances the adaptability of the system.

[0099] As an optional implementation, in the embodiment of the present invention, in actual applications, different light intensities may require the device to respond differently. Therefore, the present application can divide the light intensity into different levels by setting multiple judgment thresholds so that the device can make corresponding adjustments.

[0100] As an optional implementation, in the embodiment of the present invention, the light intensity may be affected by multiple factors and may fluctuate slightly. If judgment is made based on a single threshold, it is easy to cause misjudgment due to slight fluctuations. By setting the hysteresis judgment threshold range, the light intensity level will only be changed when the light intensity changes significantly, thereby reducing misjudgment and improving the stability of the system.

[0101] As an optional implementation, in the embodiment of the present invention, the light intensity changes continuously rather than suddenly. The present application can take this continuity into account by setting the hysteresis judgment threshold range to avoid frequent level changes due to slight changes in light intensity.

[0102] As an optional implementation, in the embodiment of the present invention, the light intensity may vary greatly in different environments and time periods. By setting multiple judgment thresholds and hysteresis judgment threshold ranges, the system can adapt to such changes and make reasonable judgments.

[0103] As an optional implementation, in an embodiment of the present invention, the present application can accurately determine the light intensity level, which helps the device to make a more reasonable response, such as adjusting the light brightness, starting or turning off the sunshade device, etc., thereby improving the user experience and the efficiency of device use.

[0104] It can be seen that the implementation Figure 2-Figure 3 Another multi-level judgment method of light intensity described can realize multi-level judgment of light intensity to more accurately control the raising and lowering of the automatic clothes drying machine.

[0105] In addition, implementation Figure 2-Figure 3 Another multi-level determination method of light intensity described can accurately determine the light intensity level, which helps related devices (such as smart lighting systems) to make reasonable responses and improve user experience.

[0112] The determination unit 403 is used to determine the current light intensity level by respectively determining the light-sensitive sampling voltage value with the first light intensity determination threshold and the second light intensity determination threshold.

[0113] As an optional implementation, in an embodiment of the present invention, the system may first obtain three key values: a photosensitive sampling voltage value (a voltage generated by a photosensitive element, reflecting light intensity), a power sampling voltage value (a voltage value of a system power supply), and a photosensitive peripheral resistance value (a resistance value connected in series or in parallel with a photosensitive element). Subsequently, the equivalent resistance calculation formula may be used to substitute these values ​​to calculate the photosensitive equivalent resistance value affected by the power supply voltage. The equivalent resistance value may reflect the total resistance of the photosensitive element and the peripheral resistance combined under the current power supply voltage and light conditions.

[0114] As an optional implementation, in an embodiment of the present invention, the fluctuation of the power supply voltage will directly affect the working state of the photosensitive element, thereby affecting the measurement of light intensity. By calculating the equivalent resistance value, the performance of the photosensitive element under the current power supply voltage can be more accurately reflected, providing a reliable basis for subsequent light intensity judgment. The present application can accurately calculate the photosensitive equivalent resistance value affected by the power supply voltage by substituting the photosensitive sampling voltage value, the power supply sampling voltage value and the photosensitive peripheral resistance value into the equivalent resistance calculation formula. This helps to eliminate the influence of power supply voltage fluctuations on the performance of the photosensitive element and improve the accuracy of light intensity measurement.

[0115] As an optional implementation, in the embodiment of the present invention, the present application can more accurately calculate the photosensitive equivalent resistance value affected by the power supply voltage by comprehensively considering the photosensitive sampling voltage, the power supply sampling voltage and the photosensitive peripheral resistance, using the equivalent resistance calculation formula. This helps to eliminate the influence of power supply voltage fluctuations on the performance of the photosensitive element, thereby improving the accuracy of light intensity measurement.

[0116] As an optional implementation, in the embodiment of the present invention, the present application uses the calculated photosensitive equivalent resistance value, the power supply sampling voltage value and the photosensitive peripheral resistance value to dynamically calculate the first light intensity judgment threshold value, so as to more accurately judge whether the current light intensity reaches or exceeds a certain level. This helps the system to automatically adjust the judgment standard according to the current ambient light conditions and power supply voltage status, thereby improving the adaptability and flexibility of the system.

[0117] As an optional implementation, in the embodiment of the present invention, under ideal conditions, the performance of the photosensitive element is known, and the theoretical photosensitive voltage value and the theoretical equivalent resistance value can be obtained through theoretical calculation. These values ​​can be used as a benchmark for actual measurement to evaluate whether the performance of the photosensitive element meets the design requirements, and help evaluate the performance deviation of the actual photosensitive element, so that the system maintains stable performance when the light intensity changes, thereby enhancing the stability and reliability of the system.

[0118] As an optional implementation, in an embodiment of the present invention, in actual application, the light intensity needs to be judged between multiple thresholds. By calculating the second light intensity judgment threshold, the system can more finely divide the light intensity level to meet the needs of different application scenarios. This helps the system to further refine the light intensity judgment standard and improve the accuracy and reliability of the judgment.

[0119] As an optional implementation, in the embodiment of the present invention, the determination of the light intensity level is the basis for the system to realize the automatic control or alarm function. By comparing the light-sensitive sampling voltage value with the determination threshold, the system can accurately determine the current light intensity level and take corresponding measures to deal with different lighting conditions. This helps the system to take corresponding control measures or send corresponding alarm signals according to the light intensity level.

[0120] As an optional implementation, in an embodiment of the present invention, the present application can dynamically set the threshold of photosensitive sampling, that is, the threshold voltage of the point is calculated to obtain the threshold equivalent resistance through a specified equivalent resistance calculation formula. Under different power supply voltages, the threshold equivalent resistance always remains fixed. When the power supply voltage changes, the present application needs to re-submit the threshold equivalent resistance into the calculation to obtain the threshold voltage after the power supply voltage changes, thereby realizing the function of setting a dynamic threshold.

[0121] As an optional implementation, in the embodiment of the present invention, the system can calculate the equivalent resistance and the light intensity judgment threshold by measuring the voltage of the photosensitive element and the known resistance value. Then, according to the comparison result of the sampled voltage and the judgment threshold, the current light intensity level is determined, and this information is sent to the elevator equipment to control its lifting, thereby realizing the requirements of accurate measurement, level division, automatic control, safety and energy saving of light intensity. In addition, the system also takes into account the changes in human body signals and light intensity to make corresponding operational adjustments.

[0122] It can be seen that the implementation Figure 4 The described judgment system can realize multi-level judgment of light intensity to more accurately control the raising and lowering of the automatic clothes drying machine.

[0123] In addition, implementation Figure 4 The judgment system described can eliminate the influence of power supply voltage fluctuation on the performance of the photosensitive element, thereby improving the accuracy of light intensity measurement.

[0132] Furthermore, if the photosensitivity sampling voltage value is less than the second light intensity judgment threshold, but is not within the second light intensity hysteresis judgment threshold range, it is judged that the current light intensity level is a low light level; wherein the maximum value of the second light intensity hysteresis judgment threshold range is less than the second light intensity judgment threshold.

[0133] As an optional implementation, in an embodiment of the present invention, the present application can divide the light intensity into three states: strong light, medium light, and weak light. When the sampled voltage is higher than the strong light threshold, it is determined to be a strong light state; when it is lower than the weak light threshold, it is determined to be a weak light state; and when it is between the strong light threshold and the weak light threshold, it is determined to be a medium light state.

[0137] and Figure 4 Compared with the judgment system, Figure 5 The determining unit 403 further includes:

[0138] As an optional implementation, in an embodiment of the present invention, the judgment subunit 4031 is also used to determine that the current light intensity is entering a strong light state when the first light intensity judgment threshold is greater than the second light intensity judgment threshold and the photosensitivity sampling voltage value is within the first light intensity hysteresis judgment threshold range, if the previous light intensity level is a medium light level, so as to determine that the current light intensity level is a strong light level.

[0141] As an optional implementation, in an embodiment of the present invention, the judgment subunit 4031 is also used to determine that the current light intensity is entering a medium light state when the first light intensity judgment threshold is less than the second light intensity judgment threshold and the photosensitivity sampling voltage value is within the first light intensity hysteresis judgment threshold range, if the previous light intensity level is a low light level, so as to determine that the current light intensity level is a medium light level.

[0142] As an optional implementation, in an embodiment of the present invention, based on actual sampling data analysis, when sunlight shines directly on the front of the remote control, the sampled voltage is at a relatively large value and changes very little regardless of morning, noon or night. However, in cloudy or rainy weather, depending on the placement of the remote control, the sampled voltage increases from 0mV and has a relatively large floating range. Therefore, the hysteresis of the set strong light threshold will be smaller, while the hysteresis of the set weak light threshold will be relatively larger.

[0143] In the embodiment of the present invention, Figure 7 and Figure 8 As shown in the figure, when the light-sensitive sampling voltage value is within a certain light intensity hysteresis judgment threshold range, the system will also consider the previous light intensity level to judge the change trend of the current light intensity. Among them, all the set thresholds need to be calculated through the power supply sampling voltage value and the set threshold resistance, and are not fixed values.

[0144] As an optional implementation, in an embodiment of the present invention, when the first light intensity judgment threshold is greater than the second light intensity judgment threshold, and the photosensitivity sampling voltage value is within the first light intensity hysteresis judgment threshold range, if the previous light intensity level is a strong light level, it is judged that the current light intensity is entering a medium light state, so as to determine that the current light intensity level is a medium light level; if the previous light intensity level is a medium light level, it is judged that the current light intensity is entering a strong light state, so as to determine that the current light intensity level is a strong light level.

[0147] As an optional implementation, in an embodiment of the present invention, when the first light intensity judgment threshold is less than the second light intensity judgment threshold, and the photosensitivity sampling voltage value is within the second light intensity hysteresis judgment threshold range, if the previous light intensity level is a medium light level, it is judged that the current light intensity is entering a low light state, so as to determine that the current light intensity level is a low light level; if the previous light intensity level is a low light level, it is judged that the current light intensity is entering a medium light state, so as to determine that the current light intensity level is a medium light level.

[0148] As an optional implementation, in the embodiment of the present invention, the system can determine the current light intensity level by comparing the photosensitive sampling voltage value and the preset light intensity judgment threshold. When the photosensitive sampling voltage value is between the two judgment thresholds, the system will also consider the corresponding hysteresis judgment threshold range and the previous light intensity level to judge the change trend of the current light intensity. This design can make the system more sensitive to changes in light intensity and can more accurately reflect the actual situation of light intensity.

[0149] As an optional implementation, in an embodiment of the present invention, for projects where the battery power supply voltage may change, the method for setting the photosensitivity threshold may refer to the method of the present application to calculate the dynamic threshold; and for projects with a stable power supply, there is no need to consider the impact of the power supply voltage on the photosensitivity threshold, and the threshold may be directly set to a fixed value. For example, for a system with a DC power supply of 5V or 3.3V, it is only necessary to calculate the threshold voltage corresponding to the power supply voltage using the above-mentioned calculated threshold resistance, and then fine-tune it according to the actual project.

[0150] As an optional implementation, in the embodiment of the present invention, the present application can divide the light intensity level more finely and reduce misjudgment by setting multiple judgment thresholds (first light intensity judgment threshold, second light intensity judgment threshold) and hysteresis judgment threshold range. And the present application is applicable to changes in different lighting environments, which enhances the adaptability of the system.

[0151] As an optional implementation, in the embodiment of the present invention, in actual applications, different light intensities may require the device to respond differently. Therefore, the present application can divide the light intensity into different levels by setting multiple judgment thresholds so that the device can make corresponding adjustments.

[0152] As an optional implementation, in the embodiment of the present invention, the light intensity may be affected by multiple factors and may fluctuate slightly. If judgment is made based on a single threshold, it is easy to cause misjudgment due to slight fluctuations. By setting the hysteresis judgment threshold range, the light intensity level will only be changed when the light intensity changes significantly, thereby reducing misjudgment and improving the stability of the system.

[0154] As an optional implementation, in the embodiment of the present invention, the light intensity may vary greatly in different environments and time periods.

The calculation of the theoretical equivalent resistance takes into account the ideal characteristics of the photosensitive element, which helps to calibrate and verify the accuracy of the actual measurement results. By accurately calculating the equivalent resistance of the photosensitive element, the present application can more accurately reflect the changes in the ambient light intensity and improve the sensitivity and accuracy of the system.

[0165] As an optional implementation, in an embodiment of the present invention, the setting of the light intensity judgment threshold is based on the characteristics of the photosensitive element and the actual application requirements, ensuring that the system can work normally under different lighting conditions. The setting of the hysteresis judgment threshold voltage is to increase the stability and reliability of the system and prevent frequent misjudgments and operations caused by slight changes in light intensity. The present application can automatically judge the current light intensity level and take corresponding operations as needed by setting the light intensity judgment threshold. At the same time, the introduction of the hysteresis judgment threshold voltage increases the system's tolerance to changes in light intensity and avoids misoperation caused by slight fluctuations.

[0171] As an optional implementation, in an embodiment of the present invention, the light intensity may fluctuate in actual applications. By setting the hysteresis judgment threshold range, the system can tolerate such fluctuations within a certain range, thereby avoiding frequent misjudgments and operations. At the same time, the system can also handle changes in light intensity more flexibly, thereby improving the adaptability and robustness of the system.

[0173] The sending unit 405 is used to determine that the unit 403 judges the photosensitive sampling voltage value respectively with the first light intensity judgment threshold and the second light intensity judgment threshold to determine the current light intensity level, and then sends the current light intensity level to the associated elevator device according to the specified coding logic communication, so that the elevator device is lifted or lowered to the specified position according to the current light intensity level; wherein the specified coding logic includes system identity information and a key value containing the current light intensity level.

[0174] As an optional implementation, in an embodiment of the present invention, the control of the elevator equipment of the present application is based on the current light intensity level and system identity information, which can ensure the accuracy and safety of the control.

[0175] and Figure 4 Compared with the judgment system, Figure 5 The judgment system includes:

[0176] The starting unit 406 is used to send the current light intensity level to the associated elevator equipment according to the specified coding logic communication by the sending unit 405, so that after the elevator equipment is lifted to the specified position according to the current light intensity level, if a human body signal is detected within a certain time period, the human sensing related operations are started; wherein, the human sensing related operations include shutting down the disinfection and voice recognition functions.

[0177] As an optional implementation, in the embodiment of the present invention, the start unit 406 is also used to start the lighting function if the current light intensity judgment result is a no-light state.

[0178] As an optional implementation, in an embodiment of the present invention, when a human body signal is detected, the system can automatically start human-sensing related operations, such as turning off disinfection and voice recognition functions, thereby avoiding unnecessary operations when people are present, improving the system's security and user experience. At the same time, the present application can also automatically provide lighting in a dark state to meet actual application needs.

[0180] In addition, implementation Figure 5 The described judgment system can accurately judge the light intensity level, which helps related devices (such as smart lighting systems) to make reasonable responses and improve user experience.
