Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0030] Example 1

[0031] Figure 1 This is a flowchart of a light intensity fault detection method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where a light intensity fault is determined. The method can be executed by a light intensity fault detection device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0032] S110. Obtain the light intensity information set of the LED combination that meets the detection duration condition.

[0033] In this embodiment, the detection duration condition can be understood as a pre-set detection time length, such as detecting light intensity over a duration of 500ms. An LED combination can be understood as a device comprising multiple LEDs, each emitting light. The light intensity information set can be understood as the collection formed by the light intensity of the LED combination detected by multiple light intensity sensors.

[0034] Specifically, multiple light intensity sensors are set at different locations in the LED assembly to detect the light intensity of the LEDs. The processor can acquire the light intensity information sent by each light intensity sensor in real time, and when the acquisition time meets the detection time condition, it integrates all the light intensity values ​​belonging to one light intensity sensor that meet the detection time condition into light intensity information. Since there are multiple light intensity sensors, there are multiple light intensity information, which are integrated into a light intensity information set.

[0035] S120. Divide the light intensity information set into arrays according to the driving square wave signal of the LED combination, and determine the light intensity array of the light intensity sensor under each target driving level. The target driving level includes the target start level and the target stop level.

[0036] In this embodiment, the driving square wave signal can be understood as a square wave-shaped signal used to drive each LED in the LED assembly to light up and turn off. The target start level can be understood as a level signal used to turn on the LED assembly, such as 1. The target stop level can be understood as a level signal used to turn off the LED assembly, such as 0.

[0037] Specifically, a fixed-frequency square wave signal is typically used to drive the LED array. For example, when the drive signal is 1, the LED array lights up; when the drive signal is 0, the LED array turns off. The processor can retrieve the drive square wave signal controlling the LED array from a preset memory. The acquisition signal corresponding to each light intensity sensor is also the same square wave signal as the drive square wave signal. The processor can determine the target drive level corresponding to the light intensity value in the light intensity information of each light intensity sensor by comparing the drive square wave signal of the LED array with the drive square wave signal corresponding to each light intensity information in the light intensity information set. This allows a light intensity array to be formed based on the light intensity values ​​belonging to the same level.

[0038] S130. Determine the light intensity fault information of the LED combination based on each light intensity array and the preset intensity threshold.

[0039] In this embodiment, the preset intensity threshold can be understood as a minimum normal light intensity threshold set for determining whether the light intensity is faulty. Light intensity fault information can be understood as information used to indicate whether the light intensity is faulty.

[0040] Specifically, the processor can determine the average light intensity of each light intensity sensor at the target start level and the average light intensity at the target stop level based on each light intensity array. By the difference between the average light intensity at the target start level and the average light intensity at the target stop level, the current light intensity corresponding to each light intensity sensor can be determined. Then, by integrating the current light intensity of all light intensity sensors and comparing it with a preset intensity threshold, it can be determined whether the light intensity of the LED combination is faulty and obtain light intensity fault information.

[0041] The technical solution of this invention acquires a light intensity information set of an LED combination that meets the detection duration condition; divides the light intensity information set into an array according to the driving square wave signal of the LED combination, and determines the light intensity array of the light intensity sensor under each target driving level, including the target start level and the target stop level; and determines the light intensity fault information of the LED combination based on each light intensity array and a preset intensity threshold. By dividing the light intensity information set of the LED combination acquired by the light intensity sensor into an array using the driving signal square wave, and combining the light intensity array obtained according to the target driving level with the preset intensity threshold, it is determined whether the LED combination has a light intensity fault, thus obtaining light intensity fault information. This achieves automatic detection of light intensity faults in the LED combination, ensuring the accuracy of light intensity determination, and thereby ensuring the normal use of the LED combination.

[0042] For example, to facilitate understanding of the arrangement of the light intensity sensor and LED combination in this invention, a specific example is provided. Figure 2 This is an example installation diagram of a light intensity fault detection method provided in Embodiment 1 of the present invention, as shown below. Figure 2 As shown, taking four light intensity sensor modules 21 as an example, several LEDs 22 form the entire LED assembly. The light intensity sensor 21 is installed between the LED assembly and the lens. The lens is set above the LED assembly. The light intensity sensor 21 is evenly distributed around the LED assembly. Figure 3 This is an example diagram of a light intensity sensor module in a light intensity fault detection method provided in Embodiment 1 of the present invention, as shown below. Figure 3 As shown, the light intensity sensor module 21 includes a light intensity sensor 211 and a light-shielding edge 22. In the light intensity sensor module 21, a light-shielding edge needs to be added in the direction of the light intensity sensor lens, that is, a light-shielding edge is added above the light intensity sensor. The light-shielding edge is used to ensure that the light intensity sensor can collect all LED light emission information while avoiding the influence of other light sources.

[0043] Example 2

[0044] Figure 4This is a flowchart of a light intensity fault detection method provided in Embodiment 2 of the present invention. This embodiment is a further refinement of the above embodiment. Figure 4 As shown, the method includes:

[0045] S401. Obtain the light intensity information set of the LED combination that meets the detection duration condition.

[0046] S402. Based on the driving square wave signal of the LED combination, determine the target start-up level and target stop-down level of the driving LED combination.

[0047] Specifically, the processor can determine the target start-up level and target stop-down level of the LED combination based on the corresponding signal value in the driving square wave signal of the LED combination. For example, 1 represents the target start-up level and 0 represents the target stop-down level.

[0048] S403. For the light intensity information corresponding to each light intensity sensor in the light intensity information set, determine the first light intensity array corresponding to the driving level that matches the target start-up level in the light intensity information.

[0049] In this embodiment, the first light intensity array can be understood as an array formed by all light intensity values ​​under the target start level.

[0050] Specifically, for the light intensity information corresponding to each light intensity sensor in the light intensity information set, the processor can determine the driving level that matches the target start-up level value in the light intensity information, determine the light intensity value under the driving level, and form the corresponding first light intensity array through the light intensity value under the driving level.

[0051] S404. Determine the second light intensity array in the light intensity information that corresponds to the drive level that matches the target off level.

[0052] In this embodiment, the second light intensity array can be understood as an array of all light intensity values ​​under the target off level.

[0053] Specifically, for the light intensity information corresponding to each light intensity sensor in the light intensity information set, the processor can determine the driving level that matches the target off level value in the light intensity information, determine the light intensity value under the driving level, and form the corresponding second light intensity array through the light intensity value under the driving level.

[0054] S405. Use the first light intensity array and the second light intensity array as the light intensity arrays under the driving level of each target.

[0055] Specifically, the processor can use the first light intensity array and the second light intensity array as light intensity arrays under the target driving level of the same sensor.

[0056] Based on the above embodiments, the step of determining the first light intensity array corresponding to the driving level that matches the target start-up level in the light intensity information can be optimized as follows:

[0057] The driving level that is the same as the target start-up level is selected from the light intensity information and used as the first level.

[0058] In this embodiment, the first level can be understood as all level signals corresponding to the target start level.

[0059] Specifically, the processor can filter out the driving level that is the same as the target startup level from the light intensity information by using the level signal value corresponding to the target startup level, and use it as the first level.

[0060] For example, if the target start level corresponds to a level signal value of 1, then the drive level with a level value of 1 is selected from the light intensity information as the first level.

[0061] A first light intensity array is generated based on the first acquisition batch and the first light intensity value to which each first level belongs.

[0062] In this embodiment, the first acquisition batch can be understood as the order in which the data is acquired. The first light intensity value can be understood as all light intensity values ​​under the target activation level. The first light intensity array can be understood as an array consisting of all light intensity values ​​under the target activation level.

[0063] Specifically, since the level square wave signal includes various level values ​​distributed with 0 and 1, and is formed in a sequential order, the processor can generate a first light intensity array based on the first acquisition batch and the first light intensity value of each first level of the level square wave signal corresponding to each light intensity sensor.

[0064] Based on the above embodiments, the step of determining the second light intensity array corresponding to the driving level that matches the target off level in the light intensity information can be optimized as follows:

[0065] The driving level that is the same as the target off level is selected from the light intensity information and used as the second level.

[0066] In this embodiment, the second level can be understood as all level signals corresponding to the target off level.

[0067] Specifically, the processor can filter out the driving level that is the same as the target shutdown level from the light intensity information by using the level signal value corresponding to the target shutdown level, and use it as the second level.

[0068] For example, if the target off level corresponds to a level signal value of 0, then the driving level with a level value of 0 is selected from the light intensity information as the second level.

[0069] A second light intensity array is generated based on the second acquisition batch and the second light intensity value to which each second level belongs.

[0070] In this embodiment, the second acquisition batch can be understood as the order in which the data is acquired. The second light intensity value can be understood as all light intensity values ​​under the target off-level condition. The second light intensity array can be understood as an array consisting of all light intensity values ​​under the target off-level condition.

[0071] Specifically, since the level square wave signal includes various level values ​​distributed with 0 and 1, and is formed in a sequential order, the processor can generate a second light intensity array based on the second acquisition batch and the second light intensity value to which each level of the level square wave signal corresponding to each light intensity sensor belongs.

[0072] S406. Determine the first average light intensity value corresponding to the light intensity sensor based on the light intensity arrays corresponding to the target start level.

[0073] In this embodiment, the first average light intensity can be understood as the average light intensity used to determine the target activation level corresponding to a light intensity sensor.

[0074] Specifically, the processor can determine the first average light intensity value corresponding to the light intensity sensor based on all light intensity arrays corresponding to the target start level and the number of light intensity values.

[0075] For example, when the drive level is 1, the values ​​of each light intensity sensor are recorded in the first light intensity array. In the diagram, m represents the number of light intensity values, and n represents the number of sensors. The first average light intensity value M1[i] is calculated as follows:

[0076]

[0077] Where i represents the corresponding sensor, and j represents the data collected by the i-th sensor in the j-th batch.

[0078] S407. Determine the second average light intensity value corresponding to the light intensity sensor based on the light intensity arrays corresponding to the target off level.

[0079] In this embodiment, the second average light intensity can be understood as the average light intensity used to determine the target off level of a light intensity sensor.

[0080] Specifically, the processor can determine the second average light intensity corresponding to the light intensity sensor based on all light intensity arrays corresponding to the target off level and the number of light intensity values.

[0081] Similarly, when the drive level is 0, the values ​​of each light intensity sensor are recorded in the second array. In the second array, the average value of the second light intensity M2[i] is calculated.

[0082]

[0083] S408. Determine the light intensity fault information of the LED combination based on the average value of each first light intensity, the average value of each second light intensity, and the preset intensity threshold.

[0084] Specifically, the processor can determine the difference based on the first average light intensity and the second average light intensity belonging to the same light intensity sensor, accumulate all the differences, compare the accumulated result with the preset intensity threshold, and determine the light intensity fault information of the LED combination based on the comparison result.

[0085] Furthermore, based on the above embodiments, the step of determining the light intensity fault information of the LED combination according to the average value of each first light intensity, the average value of each second light intensity, and the preset intensity threshold can be optimized as follows:

[0086] For each light intensity sensor, the current luminous intensity of the light intensity sensor is determined based on the difference between the first average light intensity and the second average light intensity; the average luminous intensity value of the LED combination is determined based on each current luminous intensity; the average luminous intensity value is compared with a preset intensity threshold, and the light intensity fault information of the LED combination is determined based on the comparison result.

[0087] In this embodiment, the current luminous intensity can be understood as a numerical value used to represent the luminous level of the LED combination. The average luminous intensity value can be understood as the average luminous intensity of the LED combination determined by the current luminous intensities of all sensors. The comparison result can be understood as a result used to reflect the magnitude relationship between the average luminous intensity value and a preset intensity threshold.

[0088] Specifically, the processor can subtract the average light intensity of the first light intensity from the average light intensity of the second light intensity belonging to the same light intensity sensor to obtain the current luminous intensity of the light intensity sensor. By summing the current luminous intensities of all sensors, the average luminous intensity value of the LED combination is determined. The average luminous intensity value is compared with a preset intensity threshold, and the luminous intensity fault information of the LED combination is determined based on the comparison result.

[0089] For example, the current luminous intensity of the i-th sensor It can be calculated using the following formula:

[0090]

[0091] Average luminous intensity of LED combination It can be calculated using the following formula:

[0092]

[0093] Based on the above embodiments, the step of determining the light intensity fault information of the LED combination based on the comparison results can be further optimized to include:

[0094] When the comparison result shows that the average light intensity value is greater than the preset intensity threshold, the light intensity fault-free status is taken as the light intensity fault information of the LED combination; when the comparison result shows that the average light intensity value is less than or equal to the preset intensity threshold, the light intensity fault status is taken as the light intensity fault information of the LED combination.

[0095] Specifically, when the comparison result shows that the average light intensity value is greater than the preset intensity threshold, the light intensity is not a problem and the light intensity fault-free status is taken as the light intensity fault information of the LED combination; when the comparison result shows that the average light intensity value is less than or equal to the preset intensity threshold, the light intensity is a problem and the light intensity fault is taken as the light intensity fault information of the LED combination.

[0096] For example, let With set threshold In comparison, if If the light intensity is normal, then it is assumed that there is no problem with the light intensity. If the light intensity is abnormal, it is considered that there is a problem.

[0097] The technical solution of this invention acquires a set of light intensity information from multiple light intensity sensors that meet the detection duration conditions for an LED combination. Based on the driving square wave signal of the LED combination, the light intensity information set is divided into arrays to determine a first light intensity array where the light intensity information is concentrated at a target start-up level, and a second light intensity array where the light intensity information is concentrated at a target stop-down level. The target driving level includes a target start-up level and a target stop-down level. The first light intensity array is used to determine the first average light intensity of the light intensity sensor at the target stop-down level, and the second light intensity array is used to determine the second average light intensity of the light intensity sensor at the target stop-down level. The difference between the first and second average light intensity values ​​is used to determine the current luminous intensity of the light intensity sensor. The average light intensity value determined based on each current luminous intensity is compared with a preset intensity threshold to determine the light intensity fault information of the LED combination. By combining the light intensity information sets from multiple light intensity sensors, the error of the finally determined average light intensity value is reduced, achieving automatic detection of light intensity faults in the LED combination, ensuring the accuracy of light intensity determination, and thus ensuring the normal use of the LED combination.
