Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the embodiments of the present application and are not to be construed as limiting the embodiments of the present application.
Referring to fig. 1, 2 and 3, the embodiment of the present application provides a detection method for detecting a remaining lifetime of a drying apparatus 200, the drying apparatus 200 includes a radiation structure 210, the radiation structure 210 includes a radiation source 211, and the detection method includes:
Step 011: acquiring light generated by the radiation source 211 to generate a light spot diagram, wherein the light spot diagram comprises brightness distribution data and light spots 212 formed by the radiation source 211;
the drying apparatus 200 may be a blower, a dryer, etc., and the blower is taken as an example in this application. The radiation source 211 may be a halogen lamp, and the radiation structure 210 may be a halogen lamp group formed by arranging a plurality of halogen lamps in a blower, or may be formed by a single halogen lamp; the spot diagram may be a diagram of a spot 212 formed by light emitted from a halogen lamp.
Specifically, the detection method of the present application may be applied to the detection apparatus 100 to detect the remaining life of the drying apparatus 200. The detection device 100 comprises a camera 30 and a controller 50, the radiation structure 210 comprising a radiation source 211; camera 30 may be used to capture light generated by radiation source 211 to generate a speckle pattern.
By photographing the spot 212 formed by the light emitted from the radiation source 211 by the camera 30 in the detection apparatus 100, a spot map formed by the spot 212 can be acquired, wherein the spot map contains the brightness distribution of the halogen lamp of the blower and the size of the spot 212 formed by the halogen lamp and the position coordinates of the spot 212.
Step 012: determining a first difference value according to the brightness distribution data and the preset brightness distribution data, determining a second difference value according to the size of the light spot 212 and the preset light spot size, and determining a third difference value according to the position coordinates of the light spot 212 and the preset light spot coordinates;
In some embodiments of the present application, the preset brightness distribution data, the preset spot size, and the preset spot coordinates are obtained by detecting a spot pattern for the qualified drying apparatus 200. For example, in some embodiments, the camera 30 obtains the preset brightness distribution data, the preset spot size, and the preset spot coordinates based on the brightness distribution data of the spots 212, the size data of the spots 212, and the position coordinate data of the spots 212 of the plurality of spot maps by acquiring the spot maps of the plurality of unused and qualified drying apparatuses 200. In other embodiments of the present application, a digital light field model of the radiation source 211 may also be obtained by software simulation according to the optical design data of the drying apparatus 200, and further, the preset brightness distribution data, the preset spot size, and the preset spot coordinates may be obtained according to the digital light field model.
Specifically, the value obtained by the difference between the brightness distribution data in the spot diagram of the radiation source 211 and the preset brightness distribution data is obtained by the controller 50, or the value obtained by the difference between the average brightness of the whole radiation source 211 and the average brightness of the whole preset radiation source 211 is obtained by the controller 50, or the average value of the differences obtained by the difference between the brightness of the spots 212 of the plurality of radiation sources 211 and the brightness of the spots 212 of the plurality of preset radiation sources 211 is obtained by the controller 50. If the first difference is larger, it indicates that the deviation between the actual brightness of the radiation source 211 and the preset brightness is larger.
The difference between the size of the spot 212 in the spot diagram of the radiation source 211 obtained by the controller 50 and the preset spot size is a second difference. If the second difference is larger, it indicates that the light field of the radiation source 211 is excessively scattered or excessively converged, and the deviation between the size of the formed light spot 212 and the preset light spot size is larger.
The difference between the position coordinates of the light spot 212 in the light spot diagram of the radiation source 211 obtained by the controller 50 and the preset light spot coordinates is a third difference, for example, a plane rectangular coordinate system is established by taking the center position of the preset light spot 212 on the light uniformizing screen 40 as the origin of coordinates, and the distance between the center position coordinates of the light spot 212 in the light spot diagram of the radiation source 211 obtained by the controller 50 and the origin of coordinates is the third difference. If the third difference is larger, it indicates that the light field of the radiation source 211 is displaced, and the position of the formed light spot 212 deviates from the preset light spot coordinate greatly.
Step 013: determining a deformation amplitude of the radiation source 211, the deformation amplitude being positively correlated with at least one of the first difference, the second difference, the third difference;
the deformation amplitude of the radiation source 211 may be a deformation degree of a filament of the halogen lamp in the blower, for example, displacement, bending, stretching, breaking, etc. of the filament of the halogen lamp. When the filament of the halogen lamp is deformed, the formed light field is inevitably changed. Otherwise, if the change of the light field is detected, whether the filament is deformed or not and the deformation amplitude can be reversely deduced. The change of the light field can be quantitatively studied through the first difference, the second difference and the third difference, so as to determine the deformation amplitude of the radiation source 211.
Specifically, the controller 50 in the detection apparatus 100 may determine that the deformation amplitude of the filament of the halogen lamp increases, and then at least one of the first difference, the second difference, and the third difference will also increase, that is, the deformation amplitude is positively correlated with at least one of the first difference, the second difference, and the third difference, for example, the deformation amplitude of the halogen lamp is positively correlated with the first difference, or the deformation amplitude of the halogen lamp is positively correlated with the second difference, or the deformation amplitude of the halogen lamp is positively correlated with the third difference; the first difference value and the second difference value are positively correlated with the deformation amplitude of the halogen lamp, or the first difference value and the third difference value are positively correlated with the deformation amplitude of the halogen lamp, or the second difference value and the third difference value are positively correlated with the deformation amplitude of the halogen lamp; or the first difference value, the second difference value and the third difference value are positively correlated with the deformation amplitude of the halogen lamp.
Referring to fig. 4 and 5, in some embodiments, a light spot 212 generated by a normal filament positioned at a in the radiation source 211 of the drying apparatus 200 is a ', a corresponding light spot 212 is formed at the same distance b ' after the filament moves to the right in the drawing, and a corresponding light spot 212 is formed at the same distance c ' after the filament moves to the left in the drawing and deforms. Thus, if the spot 212 of the radiation source 211 is detected as b ', which is larger than a', corresponding to the aforementioned second difference, it can be deduced that the filament moves from a to b. Similarly, if the spot 212 of the radiation source 211 is detected as c ', the size is different from a', and the position coordinates are also changed, corresponding to the second difference and the third difference, it can be deduced that the filament moves from a to c. Therefore, by changing the direction and size of the spot 212, not only can the filament be qualitatively determined, but also the displacement and deformation direction of the filament can be deduced, thereby obtaining the deformation amplitude of the radiation source 211.
Referring to fig. 5 and 6, fig. 4 shows the distribution of the light spots 212 in the normal condition of the drying apparatus 200, fig. 5 shows the distribution of the light spots 212 after the collision of the drying apparatus 200, and the radiation source 211 of the drying apparatus 200 is deformed after the collision, so that the position of the light spot 212 is changed, the more severe the collision degree is, the larger the displacement of the light spot 212 is, and therefore, the deformation amplitude of the radiation source 211 can be determined by the third difference value corresponding to the position change of the light spot 212.
Similarly, the size and brightness of the spot 212 produced by the radiation source 211 may change after it is deformed, with larger deformation resulting in lower brightness of the spot 212 and/or smaller size of the spot 212. Accordingly, the magnitude of the deformation of the radiation source 211 can be inversely deduced from the brightness change, the position change, and the size change of the spot 212.
Step 014: the remaining lifetime of the drying apparatus 200 is determined, which is inversely related to the magnitude of the deformation of the radiation source 211.
Wherein, the remaining life of the drying apparatus 200 may be a remaining time that can be normally operated.
Specifically, after determining the deformation amplitude of the radiation source 211, the controller 50 may determine the remaining lifetime of the drying apparatus 200 according to the deformation amplitude, the remaining lifetime being inversely related to the deformation amplitude of the radiation source 211, i.e. the larger the deformation amplitude, the less the remaining lifetime.
In this way, by acquiring the light spot map generated by the light emitted by the radiation source 211, the brightness distribution data included in the light spot map, the size of the light spot 212, and the position of the light spot 212 can be acquired, then the first difference value is determined according to the difference value between the preset brightness distribution data and the brightness distribution data of the light spot 212, the second difference value is determined according to the difference value between the size of the preset light spot and the size of the light spot 212, and the third difference value is determined according to the difference value between the preset light spot coordinates and the position coordinates of the light spot 212, so that the deformation amplitude of the radiation source 211 is determined according to at least one of the first difference value, the second difference value, and the third difference value, and the larger the deformation amplitude is, the smaller the residual life of the drying device 200 is, so that the deformation degree of the radiation source 211 is acquired without disassembling the drying device 200, and the detection of the residual life of the drying device 200 is indirectly realized through the light spot map.
Referring to fig. 7, in some embodiments, step 011: acquiring light generated by the radiation source 211 to generate a speckle pattern includes:
step 0111: setting a light equalizing screen 40 at a preset distance from the radiation source 211;
step 0112: light generated by the radiation source 211 is converged at the light homogenizing screen 40 and forms a light spot 212;
step 0113: the light homogenizing screen 40 is photographed to generate a spot diagram.
The detection device 100 further comprises a light homogenizing screen 40, wherein the light homogenizing screen 40 may be an object, such as a curtain, displaying the light spots 212.
Specifically, a light uniforming screen 40 is disposed at a distance from the radiation source 211, and light emitted from the radiation source 211 is converged on the light uniforming screen 40 to form a spot 212, and the camera 30 included in the detection apparatus 100 may capture the spot 212 formed on the light uniforming screen 40 to form a spot pattern.
In this way, by disposing the light uniforming screen 40 at a distance from the radiation source 211, the light emitted from the radiation source 211 can be converged on the light uniforming screen 40 to form the light spot 212, so that the camera 30 in the detection apparatus 100 can capture the light spot 212 to form a light spot map.
In some embodiments, the spot map includes actual intensities of one or more preset locations of the spot 212, the preset intensity distribution data includes theoretical intensities corresponding to the preset locations of the spot 212, and the first difference is determined based on a difference between the actual intensities and the theoretical intensities.
Specifically, by capturing the light spot 212 on the light uniformization screen 40 by the camera 30 in the detection apparatus 100, a light spot map can be formed, and the light spot map includes one or more actual brightnesses at preset positions on the light spot 212, for example, the preset positions on the light spot 212 may be at least one of a center position of the light spot 212 and an edge position of the light spot 212; taking the center position of the light spot 212 as a preset position as an example, by acquiring the actual brightness of the light spot map at the center position of the light spot 212, and then making a difference between the acquired actual brightness of the center position of the light spot 212 and the theoretical brightness corresponding to the center position of the light spot 212 in the preset brightness distribution data, the obtained difference is a first difference.
In this manner, the magnitude of deformation of the drying apparatus 200 can be determined by obtaining the first difference value by making the difference between the actual brightness at the preset position and the theoretical brightness at the preset position in the spot diagram.
Referring to fig. 5 and 8, in some embodiments, the radiation sources 211 are plural, the light spot map includes a plurality of light spots 212 formed by the plurality of radiation sources 211, and the deformation amplitude of each radiation source 211 is positively correlated with at least one of a first difference value corresponding to the light spot 212 formed by each radiation source 211, a second difference value corresponding to the light spot 212 formed by each radiation source 211, and a third difference value corresponding to the light spot 212 formed by each radiation source 211; step 014: determining the remaining life of the drying appliance 200 includes:
step 0141: determining a remaining lifetime of each radiation source 211, the remaining lifetime of each radiation source 211 being inversely related to a magnitude of deformation of each radiation source 211;
step 0142: the minimum remaining life of the remaining life of each radiation source 211 is determined to be the remaining life of the drying apparatus 200.
Specifically, the number of the radiation sources 211 of the drying apparatus 200 may be plural, that is, the number of the halogen lamps in the blower may be plural; the spot diagram may be composed of a plurality of spots 212 formed by a plurality of radiation sources 211, respectively. At least one of the first difference value corresponding to the light spot 212 formed by each radiation source 211, the second difference value corresponding to the light spot 212 formed by each radiation source 211, and the third difference value corresponding to the light spot 212 formed by each radiation source 211 is positively correlated with the deformation amplitude of each radiation source 211, that is, when the deformation amplitude of each radiation source 211 increases, at least one of the first difference value corresponding to the light spot 212 formed by each radiation source 211, the second difference value corresponding to the light spot 212 formed by each radiation source 211, and the third difference value corresponding to the light spot 212 formed by each radiation source 211 increases.
For example, the deformation amplitude of each halogen lamp is positively correlated with a first difference value corresponding to the spot 212 formed by each halogen lamp, or the deformation amplitude of each halogen lamp is positively correlated with a second difference value corresponding to the spot 212 formed by each halogen lamp, or the deformation amplitude of each halogen lamp is positively correlated with a third difference value corresponding to the spot 212 formed by each halogen lamp; or the first difference value corresponding to the light spot 212 formed by each halogen lamp and the second difference value corresponding to the light spot 212 formed by each halogen lamp are positively correlated, or the first difference value corresponding to the light spot 212 formed by each halogen lamp and the third difference value corresponding to the light spot 212 formed by each halogen lamp are positively correlated, or the second difference value corresponding to the light spot 212 formed by each halogen lamp and the third value corresponding to the light spot 212 formed by each halogen lamp are positively correlated. Or the deformation amplitude of each halogen lamp is positively correlated with the first difference value corresponding to the light spot 212 formed by each halogen lamp, the second difference value corresponding to the light spot 212 formed by each halogen lamp, and the third difference value corresponding to the light spot 212 formed by each halogen lamp.
Taking any one of the halogen lamps as an example, the deformation amplitude of the halogen lamp is positively correlated with at least one of a first difference value corresponding to the light spot 212 formed by the halogen lamp, a second difference value corresponding to the light spot 212 formed by the halogen lamp, and a third difference value corresponding to the light spot 212 formed by the halogen lamp.
The controller 50 in the detection device 100 may determine the remaining lifetime of each radiation source 211 and the remaining lifetime of each radiation source 211 is inversely related to the magnitude of the deformation of each radiation source 211, i.e. the magnitude of the deformation of each radiation source 211 increases, the remaining lifetime of each radiation source 211 will decrease. After determining the size of the remaining life of each radiation source 211, the controller 50 determines the smallest remaining life of the remaining life of each radiation source 211 as the remaining life of the blower; alternatively, the largest remaining life among the remaining lives of the respective radiation sources 211 is determined as the remaining life of the drying apparatus 200; alternatively, the average value of the remaining life of each radiation source 211 is determined as the remaining life of the drying apparatus 200.
Referring to fig. 2 and 9, in some embodiments, the radiation source 211 is one or more, and the speckle pattern includes a speckle 212 formed by a plurality of radiation sources 211.
Specifically, the number of the radiation sources 211 in the drying apparatus 200 may be one, i.e., the number of halogen lamps in the blower is one, and the spot pattern is formed by the spots 212 formed by one radiation source 211; the number of the radiation sources 211 in the drying apparatus 200 may be plural, that is, the number of the halogen lamps in the blower is plural, for example, the number of the halogen lamps in the blower is six, and one spot 212 is formed by the six halogen lamps.
In some embodiments, the spot diagram further includes band data, the deformation amplitude being positively correlated with at least one of the first difference, the second difference, the third difference, and a fourth difference of the band data and the preset band data.
The wave band data are wave bands where light rays in the light spot diagram are located. The preset band data is the band in which the light in the spot diagram of the drying apparatus 200 with no loss in lifetime is located
Specifically, the difference between the band data of the infrared light in the spot diagram obtained by the camera 30 and the preset band data is the fourth difference.
The deformation amplitude of the radiation source 211 is positively correlated with at least one of the first difference, the second difference, the third difference and the fourth difference, i.e. if the deformation amplitude of the radiation source 211 is increased, at least one of the first difference, the second difference, the third difference and the fourth difference will also be increased.
For example, the magnitude of the deformation of the halogen lamp is positively correlated with the first difference, the second difference, the third difference, or the fourth difference; the deformation amplitude of the halogen lamp is positively correlated with the first difference value and the second difference value, the deformation amplitude of the halogen lamp is positively correlated with the first difference value and the third difference value, the deformation amplitude of the halogen lamp is positively correlated with the first difference value and the fourth difference value, the deformation amplitude of the halogen lamp is positively correlated with the second difference value and the third difference value, or the deformation amplitude of the halogen lamp is positively correlated with the second difference value and the fourth difference value; the deformation amplitude of the halogen lamp is positively correlated with the first difference value, the second difference value and the third difference value, or the deformation amplitude of the halogen lamp is positively correlated with the first difference value, the second difference value and the fourth difference value, or the deformation amplitude of the halogen lamp is positively correlated with the second difference value, the third difference value and the fourth difference value; or the deformation amplitude of the halogen lamp is positively correlated with the first difference, the second difference, the third difference and the fourth difference.
In this way, the deformation amplitude of the drying apparatus 200 can be more accurately obtained by combining the first difference, the second difference, and the third difference with the fourth difference of the band data and the preset band data in the spot diagram, so that the remaining lifetime of the drying apparatus 200 can be accurately obtained.
Referring to fig. 10, in certain embodiments, step 014: determining the remaining life of the drying appliance 200 includes:
step 0143: inputting the deformation amplitude of the radiation source 211 to a preset life model to output the remaining life of the drying apparatus 200; the life model is used for representing the relation between the deformation amplitude and the residual life; the lifetime model is obtained by performing lifetime tests on the radiation sources 211 with different deformation amplitudes and fitting the data.
Specifically, by inputting the deformation amplitude of the radiation source 211 to a preset lifetime model to output the remaining lifetime of the drying apparatus 200, for example, the controller 50 in the detection apparatus 100 can input the deformation amplitude of the radiation source 211 into the preset lifetime model to output the remaining lifetime of the drying apparatus 200.
The lifetime model may be established by performing lifetime tests on the radiation sources 211 of different deformation amplitudes and fitting the resulting data. For example, a plurality of radiation sources 211 are selected to randomly perform collision, impact, drop, sway, etc. tests, respectively. After the test is completed, the filament deformation amplitude of each radiation source 211 is measured and recorded through tools such as a camera, a magnifying glass, a scale and the like, and then the service life test is carried out on each radiation source 211, namely the operation is continued until the radiation source is extinguished. And carrying out statistics on the data, and obtaining a life model related to the deformation amplitude and the residual life through functions fitting and other modes. After the deformation amplitude of the radiation source 211 is measured in the foregoing manner, the remaining lifetime of the radiation source 211 can be directly obtained through the lifetime model, so that the lifetime test is not required to be performed again.
In this way, by acquiring the remaining lives of the drying apparatuses 200 corresponding to different deformation magnitudes, a life model representing the mapping relationship between the deformation magnitudes and the remaining lives is established in advance, so that the remaining lives of the drying apparatuses 200 can be quickly obtained after the deformation magnitudes are reversely deduced from the spot diagram.
Referring to fig. 2, 3 and 11, in some embodiments, before capturing the light generated by the radiation source 211 to generate a speckle pattern, the detection method further includes:
step 015: the drying apparatus 200 is subjected to a preset number of use tests including at least one of a shaking test and a collision test.
Specifically, in certain embodiments, the test apparatus 100 includes a test device 60, the test device 60 including a fixture 61 and a driver 62; the fixing member 61 is used to fix the drying apparatus 200, and for example, the fixing member 61 may be a band, a movable ring, or the like; the driving member 62 is connected to the fixing member 61 and is used to drive the fixing member 61 to move so as to drive the drying apparatus 200 to perform a use test, for example, the driving member 62 may be connected to the fixing member 61 by a nut, a hinge.
