Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to an intelligent lighting control system based on changes in environmental conditions. Background Art

[0002] The intelligent lighting system is a system that integrates modern sensing, communication, control and lighting technologies to intelligently manage the lighting environment. It breaks through the limitation of traditional lighting that only provides basic lighting, and gives lighting more functions and value. Its core function is to automatically increase the brightness of the lamp based on feedback from the light sensor when the ambient light is below the set threshold; when it is above the threshold, the brightness is reduced to ensure that the ambient light is constant in the comfortable range, saving energy while ensuring visual comfort.

[0003] Currently, although technology can automatically adjust lighting parameters based on the environment, most existing technologies rely solely on basic sensors and software monitoring. These technologies do not deeply analyze the interdependencies between lighting devices and cannot predict potential failures. Once the lighting suddenly fails, it will have a negative impact on the user experience.

[0004] The problem we need to solve is that we have not deeply analyzed the interdependence between lighting equipment and cannot predict potential failures. To this end, we now provide an intelligent lighting control system based on changes in environmental conditions. Summary of the Invention

[0024] Furthermore, the operation instructions include equipment evaluation instructions and lighting control instructions;

[0025] When Zp∈[Z0, Z1], it means that the lighting equipment meets the lighting requirements and generates the corresponding equipment evaluation instructions;

[0026] when When , it means that the lighting equipment does not meet the lighting requirements, and the corresponding lighting control instructions are generated.

[0027] Furthermore, the abnormality analysis module analyzes the operation of the lighting equipment and determines whether there is an abnormality in the lighting equipment based on the analysis results. The process includes:

Obviously, the drawings described below are only some embodiments described in the present invention.

[0050] like Figure 1 As shown, an intelligent lighting control system based on changes in environmental conditions includes:

[0051] The data acquisition module is used to collect the operating data of the lighting and the environmental data of the location of the lighting equipment, as well as to obtain the basic parameters of the lighting equipment;

[0052] A lighting evaluation module is used to evaluate the lighting conditions of the lighting equipment based on the obtained operating data of the lighting equipment and the environmental data of the location of the lighting equipment, and generate corresponding operation instructions according to the corresponding evaluation results;

[0053] The abnormality analysis module is used to analyze the operation of the lighting equipment and determine whether there is any abnormality in the lighting equipment based on the analysis results;

[0054] The lighting control module is used to control the light intensity of the lighting equipment and modify the basic parameters of the lighting equipment according to the control results.

[0055] It should be further explained that, in the specific implementation process, the basic parameters of the lighting equipment include photoelectric conversion efficiency, rated voltage and rated current;

[0056] The operating data of the lighting equipment includes light intensity, equipment current, equipment voltage and equipment temperature;

[0057] The environmental data includes ambient light intensity and ambient temperature;

[0058] In actual situations, the data acquisition module consists of a device acquisition terminal and an environment acquisition terminal. The straight-line distance between the environment acquisition terminal and the lighting equipment is L.

[0059] At the same time, a standard evaluation cycle of a fixed length needs to be set for the lighting equipment, marked as T. The real-time operating data of the lighting equipment is obtained through the equipment collection terminal. When the operating time of the lighting equipment reaches a standard evaluation cycle, all the operating data of the lighting equipment within this standard evaluation cycle are summarized to obtain the operating data set associated with the standard evaluation cycle. At the same time, the environmental data of the location of the environmental collection terminal at the end of the standard evaluation cycle is obtained and the obtained environmental data is also associated with the standard evaluation cycle.

[0060] The obtained operating data and environmental data associated with the standard evaluation cycle are uploaded to the lighting evaluation module.

[0061] It should be further explained that, in a specific implementation, the lighting evaluation module evaluates the lighting conditions of the lighting equipment based on the obtained operating data of the lighting equipment and the environmental data of the location of the lighting equipment, and generates corresponding operation instructions based on the corresponding evaluation results, including the following process:

[0062] Constructing an environmental parameter comparison table, wherein the environmental parameter comparison table includes a plurality of ambient light intensity intervals, and each ambient light intensity interval corresponds to a reference light intensity;

[0063] The ambient light intensity in the obtained environmental data is recorded as Hg. Based on the obtained ambient light intensity and the light intensity of the lighting equipment, the actual ambient brightness at the location of the environmental collection terminal is obtained, recorded as Sg, where:

[0064]

[0065] Match the actual ambient brightness with each ambient light intensity interval in the environmental parameter comparison table, and mark the reference light intensity corresponding to the matched ambient light intensity interval;

[0066] Generate a corresponding light intensity change curve according to the light intensity in the obtained running data set;

[0067] Constructing a two-dimensional coordinate system of time with respect to light intensity, and mapping the generated light intensity change curve into the two-dimensional coordinate system, while generating a corresponding light intensity threshold line in the two-dimensional coordinate system according to the marked reference light;

[0068] The generated light intensity change curve is recorded as g(t), and the reference light intensity corresponding to the light intensity threshold line is recorded as Cg. Then, the lighting evaluation coefficient of the location of the lighting equipment is obtained, which is recorded as Zp, where:

[0069]

[0070] Setting a lighting evaluation threshold interval, denoted as [Z0, Z1], and comparing the obtained photo evaluation coefficient Zp with the set lighting evaluation threshold interval, and generating corresponding operation instructions based on the comparison result, the operation instructions including equipment evaluation instructions and lighting control instructions;

[0071] When Zp∈[Z0, Z1], it means that the lighting equipment meets the lighting requirements and generates the corresponding equipment evaluation instructions;

[0072] when When , it means that the lighting equipment does not meet the lighting requirements, and the corresponding lighting control instructions are generated;

[0073] In actual situations, when lighting equipment is in operation, it will generate light, which will interfere with the ambient light intensity collected by the environment collection terminal. Therefore, by utilizing the characteristic that the light intensity of the light source decays with distance, this interference is eliminated, thereby indirectly obtaining the actual ambient lighting intensity, thereby enabling the lighting equipment to more sensitively identify changes in environmental conditions and provide appropriate lighting.

[0074] It should be further explained that, in a specific implementation process, the abnormality analysis module analyzes the operation of the lighting equipment and determines whether the lighting equipment has an abnormality based on the analysis results. The process includes:

[0075] Generate corresponding current change curve, voltage change curve and temperature change curve respectively according to the device current, device voltage and device temperature in the obtained operation data;

[0076] Construct a plane coordinate system of current, voltage, and temperature over time, map the obtained current change curve, voltage change curve, and temperature change curve into the plane coordinate system, and obtain an operating parameter diagram of the lighting equipment within the corresponding standard evaluation period;

[0077] The obtained current change curve is recorded as I(t), the voltage change curve is recorded as U(t), and the temperature change curve is recorded as W(t);

[0078] According to the generated equipment evaluation instruction and the obtained operating parameter diagram, the performance evaluation coefficient of the lighting equipment is obtained, which is recorded as Sp, where:

[0079]

[0080] Among them, μ is the photoelectric conversion efficiency, γ is the thermal conductivity;

[0081] Set the equipment loss coefficient, denoted as S0, compare the obtained performance evaluation coefficient with the set equipment loss coefficient, and determine whether there is any abnormality in the operation of the lighting equipment based on the comparison result;

[0082] When Sp>S0, it indicates that there is an abnormality in the operation of the lighting equipment, and an equipment abnormality warning message is generated;

[0083] When Sp≤S0, it means that the lighting equipment is operating normally.

[0084] It should be further explained that, in a specific implementation process, the lighting control module controls the illumination intensity of the lighting equipment and corrects the basic parameters of the lighting equipment according to the control result, including the following process:

[0085] Comparing the obtained lighting evaluation coefficient Zp with the set lighting evaluation threshold interval according to the obtained lighting control instruction to obtain a corresponding comparison result;

[0086] When Zp<Z0, it means that the lighting equipment does not meet the current required light intensity, and a brightness increase instruction is generated;

[0087] According to the generated brightness increase instruction, the device voltage of the lighting device is increased;

[0088] When the device voltage of the lighting device is less than or equal to the rated voltage and the lighting evaluation coefficient Zp = (Z0 + Z1) / 2, the adjustment of the lighting device is completed and a basic parameter correction instruction is generated;

[0089] When the device voltage of the lighting equipment reaches the rated voltage and the lighting evaluation coefficient Zp < Z0, it indicates that the lighting equipment is abnormal and an equipment abnormality warning message is generated;

[0090] When Zp>Z1, it means that the lighting intensity of the lighting equipment is higher than the current required light intensity, and a brightness reduction instruction is generated;

[0091] According to the generated brightness reduction instruction, the voltage of the lighting equipment is reduced;

[0092] When Zp=Z1, the adjustment of the lighting equipment is completed and a basic parameter correction instruction is generated;

[0093] The basic parameters of the lighting equipment are corrected according to the generated basic parameter correction instructions.

[0094] It should be further explained that, in a specific implementation process, the process of correcting the basic parameters of the lighting equipment according to the generated basic parameter correction instruction includes:

[0095] When the basic parameter correction instruction is generated, the voltage increment and current increment when the control is completed are obtained, which are recorded as ΔU and ΔI respectively;

[0096] Get the increment of lighting intensity, recorded as ΔQ;

[0097] Then the performance attenuation coefficient of the lighting equipment is obtained, recorded as Xs, where:

[0098]

[0099] The basic parameters of the lighting equipment are modified according to the obtained performance attenuation coefficient, namely:

[0100] The corrected photoelectric conversion rate is μ*(1-Xs), and the same applies to the rated voltage and rated current;

[0101] Replace the original basic parameters of the lighting equipment with the revised basic parameters of the lighting equipment;

[0102] In actual situations, the performance of lighting equipment will gradually decline during use, resulting in deviations between the actual basic parameters of the lighting equipment and the calibrated basic parameters, which in turn will cause errors in the evaluation results of the lighting equipment, resulting in inaccurate evaluation results. By calculating the photoelectric conversion efficiency of the lighting equipment, its performance changes can be indirectly inferred, making the lighting equipment safer and more reliable during operation, and also enabling more accurate lighting control.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
