Description

Technical Field

[0001] The invention belongs to the technical field of light guide lighting, and in particular relates to a monitoring method for a light guide lighting system. Background Art

[0002] Lighting power consumption is the main power consumption point in people's daily life, commercial activities and enterprise production. Installing a light guide lighting system can effectively save more than 80% of the electricity required for daytime lighting. Most areas can install a light guide lighting system. In the long-term use process, its cost will be lower than the electricity cost required for lighting. It can significantly reduce more than 80% of the lighting energy consumption and more than 10% of the air conditioning and refrigeration consumption inside the building, greatly reducing carbon dioxide emissions and protecting the environment.

[0003] At the same time, it can allow people to have more time to work and live under natural light, protect eyesight, and reduce students' myopia, such as improving immunity, reducing depression, and protecting eyes and skin health. Removing harmful radiation, applying anti-radiation coating on the spotlight can remove harmful radiation, play a role in sterilization and prevention of various skin diseases, further ensuring human health, making the light guide lighting system more and more used;

[0004] However, the light-guiding lighting system may also age, leak or be damaged during use, which may affect the quality and intensity of the light. As for the light-guiding lighting system that uses natural light as the light source, due to the different characteristics of natural light in different regions, the natural light at different times and in different seasons is also different, which makes it difficult for users to judge whether the decline in lighting quality is related to the light-guiding lighting system. As a result, when problems occur in the light-guiding lighting system, users may be in an environment where the light quality and intensity do not meet the standards for a long time, which in turn affects the user experience and directly affects the promotion and use of the light-guiding lighting system. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a monitoring method for a light-guiding lighting system. The operating status of the light-guiding lighting system can be timely judged according to its light-guiding transmission efficiency. The detection method is simple and efficient, and can detect the light-guiding lighting system in real time, thereby ensuring the user experience and facilitating the promotion and use of the light-guiding lighting system. The established health analysis model facilitates the optimization of the light-guiding lighting system.

[0006] The object of the present invention is achieved through the following technical solutions:

[0007] A monitoring method for a light guide lighting system, step S1, obtaining the intensity information of a natural light source at an incident end and an output end of the light guide lighting system, and comparing the two to obtain the light guide transmission efficiency of the light guide lighting system;

[0008] Step S2, comparing the obtained light transmission efficiency with a preset threshold value, if the obtained light transmission efficiency is less than the preset threshold value, outputting a maintenance signal and locating the fault point;

[0009] Step S3: Collect historical data and establish a health analysis model.

[0010] In one embodiment, in step S1, it also includes:

[0011] Obtain the luminous flux of the natural light source at the incident end and the luminous flux at the output end of the light-guiding lighting system. The ratio of the luminous flux at the output end to the luminous flux at the incident end is the light-guiding transmission efficiency of the light-guiding lighting system.

[0012] Through this implementation, the luminous flux loss of the natural light source at the incident end and the output end is used as the current light transmission efficiency of the light guiding lighting system, so that the health status of the light guiding lighting system can be effectively and quickly detected in different regions, different weather conditions and different time nodes.

[0013] In one embodiment, in step S1, it also includes:

[0014] Obtain the illuminance of the natural light source at the incident end and the illuminance at the output end of the light guide lighting system. The ratio of the luminous flux at the output end to the illuminance at the incident end is the light guide transmission efficiency of the light guide lighting system.

[0015] Through this implementation, the illumination change of the natural light source at the incident end and the output end is used as the current light transmission efficiency of the light guiding lighting system, so that the health status of the light guiding lighting system can be effectively and quickly detected in different regions, different weather conditions and different time nodes.

[0016] In one embodiment, in step S1, it also includes:

[0017] Obtain the luminous flux and illuminance of the natural light source at the incident end and the luminous flux and illuminance at the output end of the light guide lighting system, the ratio of the luminous flux at the output end to the luminous flux at the incident end is used as the first transmission efficiency, the ratio of the illuminance at the output end to the illuminance at the incident end is used as the second transmission efficiency, and the lower value of the first transmission efficiency and the second transmission efficiency is selected as the light guide transmission efficiency of the light guide lighting system;

[0018] Through this implementation, the illumination change of the natural light source at the incident end and the output end and the luminous flux loss are used as evaluation parameters, and the lower value of the two is used as the current light guiding transmission efficiency of the light guiding lighting system. Not only can the health status of the light guiding lighting system be detected in different regions, different weather conditions and different time nodes, but also the accuracy of the detection can be improved to ensure the user experience.

[0019] In one embodiment, the preset threshold is 0.8. According to this embodiment, when the acquired current light guiding transmission efficiency of the light guiding lighting system is less than 0.8, it is determined that a fault occurs in the light guiding lighting system in the current state.

[0020] In one embodiment, locating the fault point includes:

[0021] Obtain thermal imaging information of standard tubes, bent tubes and extended tubes in the light-guiding lighting system, and locate the fault point based on the thermal imaging information;

[0022] Through this implementation, that is, using thermal imaging, each part of the pipeline in the light guide lighting system is inspected, and based on the results of thermal imaging, the specific fault point and the cause of the fault are determined, which facilitates operators to perform accurate maintenance.

[0023] In one embodiment, in step S1, a photodetector is used to receive natural light, a current generated in the photodetector is amplified after filtering by a filter circuit, and the amplified current is sent to a comparison circuit for comparison;

[0024] Through this implementation, that is, when a natural light source shines on the photodetector, the electrons inside the photodetector are excited by photons and generate current. The magnitude of the current directly reflects the intensity of the light. Due to the uncontrollability of the environment, the current generated may be very small. After amplifying it, it is convenient for subsequent circuits to accurately measure and process it. At the same time, a filtering circuit is used to remove irrelevant signals in the signal transmission process, thereby improving the stability and accuracy of detection.

[0025] In one embodiment, it further comprises:

[0026] Step S4, establishing an alarm system, which is used to receive the maintenance signal and output an alarm signal to an audible and visual alarm or a user terminal when receiving the maintenance signal;

[0027] Through this implementation, the user or maintenance personnel can be reminded in time to inspect the light guide lighting system.

[0028] In one embodiment, in step S3, it also includes:

[0029] The collected historical data is divided into normal state data and fault state data, and the fault state data and its corresponding fault points are classified and graded;

[0030] Through this implementation, historical data is collected and classified. On the one hand, it is convenient for users or maintenance personnel to make preliminary judgments on fault points through the obtained light transmission efficiency, thereby improving maintenance efficiency. On the other hand, it is also possible to fully grasp the operating status of the light guide lighting system, facilitate the optimization of the structure and materials of its various parts, and reduce the failure rate of the light guide lighting system.

[0031] The beneficial effects of the present invention are:

[0032] (1) By detecting the intensity changes of the natural light source at the incident end and the output end of the light guide lighting system, the operating status of the light guide lighting system can be judged. The detection method is simple and can reduce the influence of different regions and external environments on the detection accuracy;

[0034] The present invention will be described in more detail below based on embodiments and with reference to the accompanying drawings, wherein:

[0035] Figure 1 A schematic diagram showing a flow chart of an embodiment of the present invention is shown; DETAILED DESCRIPTION

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] The present invention provides a monitoring method for a light guide lighting system, comprising the following steps:

[0038] Step S1, obtaining the intensity information of the natural light source at the incident end and the output end of the light guide lighting system, and comparing the two to obtain the light guide transmission efficiency of the light guide lighting system;

[0039] Step S2, comparing the obtained light transmission efficiency with a preset threshold value, if the obtained light transmission efficiency is less than the preset threshold value, outputting a maintenance signal and locating the fault point;

[0040] Step S3: collect historical data and establish a health analysis model, divide the collected historical data into normal state data and fault state data, and classify the fault state data and its corresponding fault points;

[0041] It should be noted that, due to the different characteristics of natural light in different regions, the natural light at different times and in different seasons is also different, which makes it difficult for users to determine whether the decline in lighting quality is related to the light guide lighting system. The current detection method is relatively cumbersome, and there are large differences in various regions. For users, the detection of the light guide lighting system is relatively difficult, resulting in that when there is a problem with the light guide lighting system, the user may be in an environment where the light quality and intensity do not meet the standards for a long time, which in turn affects the user's experience. The detection method provided in this embodiment detects the intensity changes of the natural light source at the incident end and the output end of the light guide lighting system to determine the operating status of the light guide lighting system. The detection method is simple and can reduce the impact of different regions and external environments on the detection accuracy, so as to facilitate the timely discovery of faults in the light guide lighting system, ensure the lighting needs of users, improve user experience, and facilitate the promotion and use of the light guide lighting system.

[0042] In one embodiment, in step S1, it further includes:

[0043] Obtain the illuminance of the natural light source at the incident end and the illuminance at the output end of the light-guiding lighting system. The ratio of the luminous flux at the output end to the illuminance at the incident end is the light-guiding transmission efficiency of the light-guiding lighting system. That is, the illuminance change of the natural light source at the incident end and the output end is used as the current light-guiding transmission efficiency of the light-guiding lighting system. This can effectively and quickly detect the health status of the light-guiding lighting system in different regions, different weather conditions and different time nodes.

[0044] In one embodiment, in step S1, it further includes:

[0045] Obtain the illuminance of the natural light source at the incident end and the illuminance at the output end of the light-guiding lighting system. The ratio of the luminous flux at the output end to the illuminance at the incident end is the light-guiding transmission efficiency of the light-guiding lighting system. That is, the illuminance change of the natural light source at the incident end and the output end is used as the current light-guiding transmission efficiency of the light-guiding lighting system. This can effectively and quickly detect the health status of the light-guiding lighting system in different regions, different weather conditions and different time nodes.

[0046] In one embodiment, in step S1, it further includes:

[0047] The luminous flux and illuminance of the natural light source at the incident end and the luminous flux and illuminance at the output end of the light-guiding lighting system are obtained, the ratio of the luminous flux at the output end to the luminous flux at the incident end is used as the first transmission efficiency, and the ratio of the illuminance at the output end to the illuminance at the incident end is used as the second transmission efficiency. The lower value of the first transmission efficiency and the second transmission efficiency is selected as the light-guiding transmission efficiency of the light-guiding lighting system, that is, the illuminance change of the natural light source at the incident end and the output end and the luminous flux loss are used as evaluation parameters, and the lower value of the two is used as the current light-guiding transmission efficiency of the light-guiding lighting system. This can not only detect the health status of the light-guiding lighting system in different regions, different weather conditions and different time nodes, but also improve the accuracy of the detection and ensure the user experience;

[0048] Further, in step S2, after obtaining the current light transmission efficiency of the light guide lighting system, it is compared with a preset threshold value, the preset threshold value is 0.8, if the current light transmission efficiency is not less than the preset threshold value, it is judged that the light guide lighting system in the current state has no fault, if the current light transmission efficiency is less than the preset threshold value, it is judged that the light guide lighting system in the current state has a fault, that is, output a maintenance signal and locate the fault point, by obtaining the thermal imaging information of the standard tube, the bent tube and the extension tube in the light guide lighting system, according to the result of the thermal imaging, the fault point is accurately located, which is convenient for the operator to perform precise maintenance, and the output maintenance signal can be sent to a device such as an audible and visual alarm device to remind the user;

[0049] Further, in step S4, an alarm system is established, which is used to receive the maintenance signal sent in step S2, and output an alarm signal to an audible and visual alarm or a user terminal when receiving the maintenance signal, so as to promptly remind the user or maintenance personnel to perform maintenance on the light guide lighting system;

[0050] In one embodiment, in step S1, a photodetector is used to receive natural light, and the current generated in the photodetector is amplified after filtering by a filter circuit, and the amplified current is sent to a comparison circuit for comparison. That is, when the natural light source is irradiated on the photodetector, the electrons inside the photodetector are excited by photons and generate current. The magnitude of the current directly reflects the intensity of the light. Due to the uncontrollability of the environment, the generated current may be very small. After amplifying it, it is convenient for subsequent circuits to accurately measure and process it. At the same time, a filter circuit is used to remove irrelevant signals in the signal transmission process to improve the stability and accuracy of the detection. A photodiode sensor can be used as a photodetector. Based on the photoelectric effect and the internal photoelectric effect, when light is irradiated on the photodiode, the photon energy is absorbed by the semiconductor material, causing the electron to transition from the valence band. To the conduction band, forming electron-hole pairs, these electron-hole pairs are separated under the action of the built-in electric field and move to the two poles, thereby generating photocurrent. The magnitude of the photocurrent is proportional to the intensity of the incident light, so the intensity of the incident light can be inferred by measuring the photocurrent. The photodiode sensor detects light signals through the photoelectric effect. When the light beam is irradiated on the photodiode, it will stimulate the flow of photoelectrons to form a current proportional to the light intensity. By detecting the magnitude of this current, the magnitude of the light intensity can be determined. The photodiode sensor has a high sensitivity to light signals and can detect weak light signals. It has a fast response speed and can quickly convert light signals into electrical signals. The noise generated during the operation is low, which is conducive to improving the measurement accuracy. It has good stability and can maintain a high measurement accuracy to ensure the detection effect.
