Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular, to an air-cooled fish-aggregating lamp and a method for replacing the fan of the air-cooled fish-aggregating lamp. Background Art

[0002] Using fish-aggregating lamps to attract fish schools is an important means in marine fishing operations. Due to advantages such as high energy efficiency and long lifespan, LED fish-aggregating lamps have gradually replaced traditional metal halide lamps. However, there are still significant problems in the long-term use of existing LED fish-aggregating lamps in the marine environment, especially the insufficient reliability of the heat dissipation system, which affects the overall lifespan of the lamps and the fishing operation efficiency.

[0003] Currently, LED fish-aggregating lamps in the prior art usually adopt an active heat dissipation method, that is, the temperature of the lamp beads and the radiator is forced to be reduced through a fan assembly. However, the marine environment is characterized by high salt fog and high humidity. During long-term operation, the fan blades are prone to corrosion or mechanical wear, resulting in a high failure rate. Once the fan blades are damaged, the heat dissipation efficiency drops sharply, causing the temperature of the radiator to rise rapidly, and ultimately leading to overheating and burning of the LED lamp beads, seriously affecting the service life of the lamps and the continuity of fishing operations.

[0004] In addition, the fan assembly of existing fish-aggregating lamps is usually installed on the internal structure of the rear cover by means of screw fixation. When the fan blades are damaged, users need to disassemble the rear cover and remove the fixing screws to replace them. This structural design makes the repair process cumbersome, and it is difficult for ordinary users to operate by themselves. Usually, the entire lamp needs to be returned to the factory for repair, which not only increases transportation and time costs but also significantly reduces the efficiency of fishery production. Summary of the Invention

[0005] In view of this, an embodiment of the present invention provides an air-cooled fish-aggregating lamp to solve the technical problem of difficult repair caused by the unreasonable fixing method of the fan blades of the existing air-cooled fish-aggregating lamp.

[0006] The technical solution adopted by the present invention is as follows: In a first aspect, the present invention provides an air-cooled fish-aggregating lamp, comprising: A substrate; A light-emitting unit, mounted on the substrate; A heat dissipation member, including a mounting portion and a heat dissipation structure, the substrate is mounted on the mounting portion, and the heat dissipation structure is located on the side of the mounting portion facing away from the substrate; A middle plate, connected to the heat dissipation member, the middle plate is located on the side of the heat dissipation structure facing away from the substrate, an installation wall is provided on the middle plate, the installation wall encloses an installation cavity, and a clamping structure is provided on the installation wall; A fan assembly, including a housing and a fan blade, the fan blade is mounted in the housing, and the housing includes a first mounting plate; When the first mounting plate is located in the mounting cavity and at the first angular position, the first mounting plate is located outside the clamping structure; When the first mounting plate is located in the mounting cavity and at the second angular position, the first mounting plate is clamped with the clamping structure.

[0007] In a second aspect, the present invention also provides a method for replacing the fan of an air-cooled fish-aggregating lamp, which is used to replace the fan assembly in the air-cooled fish-aggregating lamp described in the first aspect. The method includes: S1: Disassemble the cover from the housing to expose the opening on the housing; S2: Disconnect the connecting wire of the fan assembly from the power supply; S3: Rotate the old fan assembly to the angular position where the first mounting plate is disengaged from the clamping structure; S4: Take out the old fan assembly from the air-cooled fish-aggregating lamp; S5: Place the new fan assembly from the opening to the first angular position in the mounting cavity; S6: Rotate the new fan assembly to the position where the first mounting plate is clamped with the clamping structure; S7: Cover the cover on the housing and insert the positioning post on the cover into the second through hole.

[0008] Advantageous effects: The air-cooled fish-aggregating lamp and the method for replacing the fan of the air-cooled fish-aggregating lamp of the present invention enclose a mounting cavity through the mounting wall on the middle plate, enabling the first mounting plate in the fan assembly to rotate within a certain angle, ensuring that the fan assembly is always coaxial with the heat dissipation structure, and avoiding poor heat dissipation caused by installation deviation. And when the fan assembly is placed at the first angular position in the mounting cavity, the fan assembly has been preliminarily limited. At this time, only by rotating the fan assembly to make the first mounting plate rotate to the position clamped by the clamping structure can the detachable installation and fixation of the fan assembly with the middle plate be realized. The installation structure of the present invention can quickly and accurately install the fan assembly in place through the two-step installation method of placing the first mounting plate in the mounting cavity and rotating the fan assembly to the clamping angular position. When disassembling, first rotate the fan assembly to the angular position where the first mounting plate is separated from the clamping structure, and then take out the fan assembly from the mounting cavity. Therefore, the disassembly process of the fan is also very convenient and fast, which is beneficial for users to replace the fan in a timely manner by manual operation without the help of additional tools. Based on the clamping of the first mounting plate with the clamping structure, the present invention inserts the positioning post on one side of the cover into the second through hole, which can ensure that the fan assembly will not loosen during the vibration of the hull and its own vibration.

[0012] Embodiment 1 As Figure 1 and Figure 2 shown, this embodiment provides an air-cooled fish-aggregating lamp, which mainly includes a substrate 1, a light-emitting unit 2, a heat sink 3, a middle plate 4, and a fan assembly 5.

[0013] As Figure 3 shown, the substrate 1 is used to mount the light-emitting unit 2, and the light-emitting unit 2 can adopt LED lamp beads; based on the excellent thermal conductivity and structural stability of aluminum materials, the substrate 1 in this embodiment can adopt an aluminum substrate 1 to meet the high-efficiency heat dissipation requirements of LED lighting. Aluminum has a relatively high thermal conductivity and can quickly conduct heat from the LED chip to the radiator to avoid heat accumulation. The thermal expansion coefficients of the LED chip and the aluminum substrate 1 are relatively close. When the temperature changes, the thermal stress between the aluminum substrate 1 and the LED solder joints is small, which can reduce the risk of solder joint cracking and avoid desoldering caused by repeated thermal expansion and contraction. The aluminum substrate 1 has relatively high mechanical strength and can bear the installation requirements of high-power LEDs. At the same time, it is suitable for high-density LED arrays such as fish-aggregating lamps, and is vibration-resistant and impact-resistant, suitable for harsh environments such as ships. Compared with copper substrates, aluminum substrates achieve a better balance among thermal conductivity, weight, and cost.

[0014] As shown Figure 4 in FIG. 1, the heat sink 3 in this embodiment includes a mounting portion 31 and a heat dissipation structure 32. The substrate 1 is mounted on the mounting portion 31, and the heat dissipation structure 32 is located on the side of the mounting portion 31 facing away from the substrate 1. One side of the substrate 1 is mounted with a light-emitting element, and the other side is connected to the mounting portion 31 of the heat sink 3. In this way, the heat of the light-emitting unit 2 can be quickly conducted to the heat sink 3 on the back of the light-emitting unit 2 through the substrate 1, and the heat generated by the light-emitting unit 2 is dissipated through the heat sink 3, thus avoiding heat accumulation. In specific implementation, mounting holes can be processed on the mounting portion 31 and the substrate 1, and then the heat sink 3 and the substrate 1 are connected by using threaded connectors through the mounting holes. The heat dissipation mechanism includes a plurality of heat dissipation fins, and these heat dissipation fins are distributed in multiple circles annularly from the inside to the outside, and the fins in adjacent two circles of annular distribution are staggered in the circumferential direction, so that the heat can be more dispersed during the conduction process, thereby improving the heat dissipation efficiency.

[0015] The middle plate 4 in this embodiment is connected to the heat sink 3, and the middle plate 4 is located on the side of the heat dissipation structure 32 facing away from the substrate 1. As shown Figure 5 in FIG. 2, an installation wall is provided on the middle plate 4, and the installation wall encloses an installation cavity 42, and a clamping structure is provided on the installation wall. In specific implementation, connection columns can be provided on the middle plate 4 and the mounting portion 31, and connection holes are provided in the connection columns, and then the middle plate 4 and the mounting portion 31 are connected by using threaded connectors through the connection holes. The middle plate 4 in this embodiment includes a bottom wall and an installation wall, the installation wall is located on the side of the bottom wall facing away from the heat sink 3, and the wall surface of the installation wall extends from the surface of the bottom wall in the direction facing away from the heat sink 3.

[0016] As shown Figure 6 in FIG. 3, the fan assembly 5 in this embodiment includes a housing 51 and a fan blade 52, the fan blade 52 is mounted in the housing 51, and the housing 51 includes a first mounting plate 511; the fan assembly 5 can be a fan assembly 5 using a DC fan. The fan assembly 5 is mounted on the side of the middle plate 4 facing away from the heat sink 3. The DC fan is driven by a brushless motor, with concentrated air volume and high efficiency, which can quickly take away the heat of the LED lamp beads and the radiator, and at the same time has a low operating noise. The fan speed can be dynamically adjusted by pulse width modulation (PWM), and the heat dissipation intensity can be intelligently adjusted according to the temperature of the lamp, avoiding overheating or insufficient heat dissipation. The DC fan has lower energy consumption under the same air volume, reduces the power consumption of the overall fish aggregating lamp, and prolongs the battery life of the fishing boat. The DC fan has no carbon brush wear problem and has a longer life, and is suitable for the fish aggregating lamp that works continuously for a long time. The DC fan is usually lighter than the AC fan of the same specification, which is convenient to be integrated into the fish aggregating lamp structure, reduces the overall weight, and is more suitable for the suspended lamp on the fishing boat.

[0017] In this embodiment, the quick detachable connection of the fan assembly 5 is achieved by the snap connection structure with the first mounting plate 511. The cross-sectional shape of the installation cavity 42 can be designed to allow the first mounting plate 511 to rotate within a certain angle, for example, it can rotate from the first angular position to the second angular position.

[0018] As Figure 7 shown, when the first mounting plate 511 is located in the installation cavity 42 and at the first angular position, the first mounting plate 511 is outside the snap connection structure; When installing the fan assembly 5, the first mounting plate 511 can be first placed in the installation cavity 42 and the first mounting plate 511 is in the angular position outside the snap connection structure, that is, the aforementioned first angular position. At this time, the peripheral wall of the installation cavity 42 can be used to preliminarily position the fan assembly 5 so that the fan assembly 5 is located in the installation cavity 42 and the center of the fan assembly 5 is aligned with the center of the safety cavity. Since the first mounting plate 511 is outside the snap connection structure at this time, the fan assembly 5 can rotate within a certain range and can also be easily taken out from the installation cavity 42, which provides convenience for the subsequent replacement and repair of the fan assembly 5.

[0019] As Figure 8 shown, when the first mounting plate 511 is located in the installation cavity 42 and at the second angular position, the first mounting plate 511 is snap-connected to the snap connection structure.

[0020] After the fan assembly 5 is placed at the first angular position in the installation cavity 42, the fan assembly 5 has been preliminarily limited. At this time, only the fan assembly 5 needs to be rotated so that the first mounting plate 511 rotates to the position where it is snap-connected by the snap connection structure to achieve the detachable installation and fixation of the fan assembly 5 to the middle plate 4. The installation structure of this embodiment can quickly and accurately install the fan assembly 5 in place through a two-step installation method of placing the first mounting plate 511 in the installation cavity 42 and rotating the fan assembly 5 to the snap connection angular position. When disassembling, first rotate the fan assembly 5 to the angular position where the first mounting plate 511 is separated from the snap connection structure, and then take out the fan assembly 5 from the installation cavity 42. Therefore, the disassembly process of the fan is also very convenient and fast, which is beneficial for users to replace the fan in a timely manner by hand without the help of additional tools.

[0021] In this embodiment, four clamping structures are provided on the installation wall, and the four clamping structures are arranged at the four corner points of the first mounting plate 511 when it is in the second corner position. The outer shape of the first mounting plate 511 in the fan assembly 5 can be generally rectangular, so the positions of the four corners of the first mounting plate 511 are the four corner points of the first mounting plate 511. In this embodiment, the positions of the four clamping structures on the installation wall are such that when the first mounting plate 511 rotates to the second corner position, the four clamping structures are respectively at the four corner points of the first mounting plate 511, and each corner point corresponds to a clamping structure. In this way, when the fan assembly 5 rotates to the position where the first mounting plate 511 is in the second corner position, the four clamping structures on the installation wall respectively clamp the four corners of the first mounting plate 511, thereby keeping the position of the fan assembly 5 stable after installation.

[0022] As Figure 5 shown, in this embodiment, the installation wall includes a first peripheral wall 411 and a second peripheral wall 412. The first peripheral wall 411 and the second peripheral wall 412 are alternately arranged along the circumferential direction of the installation wall. The wall surface of the first peripheral wall 411 is rectangular, and the second peripheral wall 412 includes multiple rectangular wall surfaces, and the angle between adjacent two wall surfaces is an obtuse angle; When the first mounting plate 511 rotates from the first corner position to the second corner position, the corner points of the first mounting plate 511 face the second peripheral wall 412. In this embodiment, the first peripheral wall 411 is set as a structure of a rectangular plane. In this way, when the first mounting plate 511 rotates in the direction away from the second corner position, it is blocked by the first peripheral wall 411 and cannot rotate, thus avoiding the reverse rotation of the fan assembly 5 during installation. The second peripheral wall 412 is set in a form of multiple segments, each segment is a rectangular wall surface, and the angle between adjacent two wall surfaces is an obtuse angle. In this way, the corner points of the first mounting plate 511 can rotate accurately and flexibly towards the second position under the guidance of the second peripheral wall 412, which is beneficial to the quick and accurate installation of the fan assembly 5.

[0023] As Figure 5 shown, in this embodiment, the clamping structure includes a clamping plate 431 and a clamping convex. The clamping plate 431 extends from the end of the installation wall facing away from the heat dissipation member 3 towards the center of the installation cavity 42. The clamping convex is located on the surface of the clamping plate 431 facing the heat dissipation member 3. A first through hole 5111 is provided on the first mounting plate 511. When the first mounting plate 511 rotates from the first corner position to the second corner position, at least a part of the first mounting plate 511 enters between the clamping plate 431 and the bottom wall of the installation cavity 42 from outside the clamping plate 431 and at least a part of the clamping convex is located in the first through hole 5111.

[0024] The card board 431 of this embodiment is formed by extending from one end of the installation wall facing away from the heat dissipation member 3 towards the center of the installation cavity 42. In this way, the card board 431 has a structure of a cantilever beam with one end connected to the installation wall and the other end being a free end, which not only makes the root structure of the card board 431 stable, but also has good elasticity, facilitating the clamping of the first installation plate 511.

[0025] In this embodiment, the quick and reliable installation of the fan assembly 5 is achieved through the combined structure of the card board 431 and the card projection. While rotating the fan assembly 5 to the second angular position to make the first installation plate 511 rotate in place, by utilizing the elasticity of the card board 431 and combining with the raised structure 47 of the card projection, the first installation plate 511 is pressed between the bottom wall and the card board 431, and the elasticity of the card board 431 is used to make a part of the card projection embed into the first through hole 5111. Thus, while positioning with the card projection and the first through hole 5111, the card projection restricts the first installation plate 511, thereby reliably fixing the first installation plate 511 at an accurate position. The entire clamping process only requires rotating the first installation plate 511 in place to achieve accurate and reliable installation. Therefore, no other tools are needed, which is not only convenient for installation, but also has an accurate installation position and high structural reliability after installation, facilitating the stable operation of the fan assembly 5.

[0026] In this embodiment, gaps 433 separated from the rest of the peripheral wall are provided on both sides of the part of the peripheral wall connected to the card board 431.

[0027] As Figure 5 shown, in this embodiment, the second peripheral wall 412 is divided into multiple parts by the gaps 433. One part is connected to the card board 431, and this part is separated from the surrounding second peripheral wall 412 by the gaps 433. In this way, the card board 431 can be fully deformed to clamp the first installation plate 511 in the second angular position. During disassembly, the card board 431 also has sufficient deformation space so that the card projection can be withdrawn from the first through hole 5111 only by rotating the fan assembly 5, thus realizing the quick manual disassembly of the fan assembly 5.

[0028] As Figure 5As shown, in this embodiment, the middle plate 4 further includes a limiting portion 44. The limiting portion 44 extends from the peripheral wall towards the clamping plate 431. The limiting portion 44 is located on one side of the clamping plate 431 in a preset direction, and the preset direction is the direction in which the first mounting plate 511 rotates from the first angular position to the second angular position. When the first mounting plate 511 rotates from the first angular position to the second angular position, the first mounting plate 511 just abuts against the limiting portion 44. At this time, the first mounting plate 511 is blocked by the limiting portion 44 and cannot continue to rotate, thereby accurately limiting the first mounting plate 511 at the second angular position. Since the limiting portion 44 is located on one side of the clamping plate 431 in the preset direction, the first mounting plate 511 can be limited after the clamping plate 431 is clamped with the first mounting plate 511, which can improve the installation accuracy of the fan assembly 5 and also improve the installation accuracy of the fan assembly 5.

[0029] In this embodiment, a first notch 45 is provided on the bottom wall of the installation cavity 42, and the projection of the clamping plate 431 on the bottom wall is located in the first notch 45. With the foregoing structure, the first notch 45 can just be located directly below the clamping plate 431, enabling the clamping plate 431 to have a large deformation space. In this way, when disassembling the fan assembly 5, only by rotating the fan assembly 5 can the clamping protrusion quickly exit from the first through hole 5111, thus facilitating disassembly.

[0030] In this embodiment, a positioning groove 46 complementary to the outer contour of the first mounting plate 511 is provided on the bottom wall. When the mounting plate is in the first angular position, at least a part of the first mounting plate 511 is located in the positioning groove 46, and protrusions 47 are provided at the corner positions of the positioning groove 46. When the user installs the fan assembly 5, the first mounting plate 511 can be first placed in the positioning groove 46, and then the fan assembly 5 is rotated to the second angular position, thereby quickly achieving the accurate installation of the fan assembly 5. When disassembling the fan assembly 5, the fan assembly 5 can also be first rotated to the position where the first mounting plate 511 is located in the positioning groove, and then the fan is taken out, thereby realizing the quick disassembly of the fan assembly 5.

[0031] As Figure 1 and Figure 9 As shown, the air-cooled fish attracting lamp of this embodiment further includes a housing 6 and a cover body 7. The housing 6 covers one end of the fan blade 52 facing away from the heat dissipation member 3. An opening 61 is provided at one end of the housing 6 facing away from the heat dissipation member 3. The cover body 7 covers the opening 61. A card slot 63 is provided on the housing 6, and a buckle 71 is provided along the circumferential direction at the edge of the cover body 7. The buckle 71 is snapped into the card slot 63; The cover body 7 can prevent the fish attracting lamp from sucking in foreign objects such as leaves, sundries, flies and insects. The cover body 7 is fixed by the buckle 71 type and can be disassembled and assembled without tools.

[0032] As Figure 6 shown, the housing 51 includes a second mounting plate 512 which is located on the side of the first mounting plate 511 facing away from the heat dissipation component. A second through hole 5121 is provided on the second mounting plate 512. A positioning post 72 is provided on the side of the cover 7 facing the second mounting plate 512, and at least a part of the positioning post 72 is inserted into the second through hole 5121.

[0033] The positioning posts 72 provided on the cover 7 are aligned with the second through holes 5121 at the four corners of the fan. After the cover is closed, the positioning posts can extend into the fan fixing holes to prevent the fan from rotating and moving, thereby further improving the reliability of installation.

[0034] As Figure 2 shown, the air-cooled fish attracting lamp further includes a glass plate 8, an inner reflector 9 and an outer reflector 10. A third through hole is provided in the middle of the substrate 1. The inner reflector 9 is installed at the third through hole, and the outer light-emitting cover is located at the outer edge of the substrate 1. The outer reflector 10 is pressed on the substrate 1 by the glass plate 8. The inner reflector 9 is installed at the center position of the substrate 1, the outer light-emitting cover is installed on the outer ring of the substrate 1, and the light-emitting units 2 are distributed in the annular area between the inner reflector 9 and the outer reflector. In this way, the light emitted by the light-emitting units 2 can be irradiated to a preset area after being reflected by the inner and outer reflectors, avoiding excessive dispersion of light.

[0035] The air-cooled fish attracting lamp further includes a bracket 11 which is rotatably connected to the heat dissipation member 3 through a connecting component. The connecting component includes a toothed disc 121 and a scale disc 122. The scale disc 122 is provided with scales indicating angles. One of the scale disc 122 and the toothed disc 121 is provided with circumferentially distributed teeth, and the other is provided with circumferentially distributed tooth grooves. The teeth are engaged in the tooth grooves. The toothed disc 121 is fixed on the heat dissipation member 3, and the scale disc 122 is connected to the bracket 11. When the bracket 11 is rotated to a suitable angle, the teeth are engaged in the tooth grooves, so that the irradiation direction of the fish attracting lamp can be flexibly adjusted after installation.

[0036] A first waterproof connector 14 is provided at the end of the power cord 13. The fan assembly 5 further includes a power input line 15. A second waterproof connector 16 is provided at one end of the power input line 15, and the second waterproof connector 16 is used for plugging into the first waterproof connector 14. After adopting the foregoing structure, the power supply of the fan can be connected to the power source through the waterproof connector, so that the power source can be simply and quickly plugged and unplugged, thus facilitating replacement.

[0037] A wire hiding groove 62 is provided on the outer shell 6, and the wire hiding groove 62 is used for placing the power cord 13. After the fan assembly 5 is installed and the waterproof connectors are plugged in, the power input line 15 can be hidden in the wire hiding groove 62.

[0038] Example 2 like Figure 10 As shown, this embodiment provides a method for replacing the fan blades 52 of an air-cooled fish-collecting lamp, which is used to replace the fan assembly 5 in the air-cooled fish-collecting lamp in Example 1, and the method includes: S1: Remove the cover 7 from the housing 6 to expose the opening 61 on the housing 6; Since the cover body 7 is connected to the housing 6 via the buckle 71 , the buckle 71 can be opened by hand to remove the cover body 7 .

[0039] S2: Disconnect the connection cable between the fan assembly and the power supply; During specific operation, the second waterproof connector 16 of the power input line 15 may be disconnected from the first waterproof connector 14 .

[0040] S3: Rotate the old fan assembly 5 to an angular position where the first mounting plate 511 is disengaged from the clamping structure; In specific implementation, the fan assembly 5 can be rotated around the rotating shaft in a direction away from the clamping structure until the first mounting plate 511 is disengaged from the clamping structure.

[0041] S4: Take out the old fan assembly 5 from the air-cooled fish collecting lamp; After the cover 7 is disassembled, the opening 61 of the housing 6 is opened, and the old fan assembly 5 can be taken out through the opening 61. Before taking out, the power input line 15 hidden in the line-hiding groove 62 can be taken out first, and the waterproof connector can be disassembled.

[0043] S6: Rotate the new fan assembly 5 to a position where the first mounting plate 511 is engaged with the engaging structure; After the clamping, the lower part of the fan assembly 5 is fixed on the middle plate 4. After the clamping is in place, the waterproof connector can be plugged in, and then the power input line 15 is hidden in the line-hiding groove 62.

[0044] S7: Cover the cover body 7 on the housing 6 , and make the positioning column 72 on the cover body 7 plug into the second through hole 5121 .

[0045] After the cover body 7 is closed, the positioning post 72 extends into the second through hole 5121 of the second mounting plate 512 to prevent the fan from rotating and moving.

[0046] like Figure 11 As shown, before the step S1: removing the cover 7 from the housing 6 to expose the opening 61 on the housing 6, the following steps are also included: S01: Obtain the preset conditions satisfied when the fan is replaced; For example, the current of the fan being too small or too large can be used as the condition satisfied during replacement.

[0047] S02: Detect the electrical parameters related to the fan; The electrical parameters related to the fan include electrical parameters such as the drive current, drive voltage, and operating power of the fan S03: Determine whether the fan needs to be replaced according to the electrical parameters and the preset conditions; When the electrical parameters meet the preset conditions, it can be determined that the fan needs to be replaced.

[0048] S04: If the fan needs to be replaced, generate a replacement prompt signal and adjust the working state of the air-cooled fish-aggregating lamp.

[0049] Among them, the prompt signal can be sent by the fan indicator light on the cover 7 emitting light, thereby prompting the user to replace the fan. After generating the replacement prompt signal, the lamp can be turned off to avoid damage to the lamp due to overheating.

[0050] The said S03 further includes: S031: Periodically record the electrical parameters of the fan and store them in segments with a predetermined time period to form multiple historical operation data segments; S032: Obtain the trend slope value of the fan electrical parameters corresponding to each data segment according to the data segments; The obtaining the trend slope value of the fan electrical parameters corresponding to each data segment according to the data segments includes: Perform smoothing processing on each data segment; In this embodiment, smoothing processing is performed on each data segment. For example, the exponentially weighted moving average (EWMA) or the moving average method is used to remove short-term noise caused by environmental interference; Perform linear fitting on the smoothed data segments, and calculate the trend slope value of the fan electrical parameters according to the fitting result; In this embodiment, the least squares method is used for linear fitting of each preprocessed data segment to calculate the trend slope value of the fan electrical parameters; the electrical parameters of the fan include current or rotational speed.

[0051] S033: Analyze the trend slope value to determine whether the fan calculation enters an accelerated degradation state; Include: Obtain the trend slope of the latest data segment; Obtain the average value of the trend slopes of several previous data segments; Calculate the change ratio of the trend slope according to the trend slope of the latest data segment and the average value; When the change ratio exceeds the set warning threshold, it is determined that the fan enters the accelerated degradation state; To ensure the accuracy of the judgment, it can be set that only when the trend slope change ratios of two or more consecutive latest data segments all exceed the above set threshold, it is finally determined that the fan actually enters the stable accelerated degradation state, and at this time, the subsequent comprehensive degradation index evaluation can be prepared.

[0052] S034: If so, obtain the stage-based comprehensive degradation index according to the trend characteristic values of the fan electrical parameters and the time sequence relationship of the characteristic values in each stage; Specifically include: Divide the historical data into multiple consecutive trend analysis stages according to the trend slope values corresponding to each data segment, and obtain the trend characteristic values of the fan electrical parameter changes in each stage; Determine the weights of each trend characteristic value according to the time sequence relationship of the stages to which the trend characteristic values belong; Assign the largest weight to the trend characteristic value of the most recent stage, the second largest weight to the second most recent stage, and gradually decrease the weights of earlier stages in turn to highlight the importance of recent data; Perform weighted comprehensive calculation on the trend characteristic values of each historical stage according to the weights of each trend characteristic value to obtain the stage-based comprehensive degradation index. This index reflects the cumulative effect of the fan degradation in multiple stages; After each initial operation or replacement and maintenance of the fan, automatically recalculate and update the benchmark value of the stage-based comprehensive degradation index under normal operation conditions to dynamically adapt to the individual differences of the fan and the changes in environmental conditions; Specifically, after each initial operation or replacement and maintenance of the fan, the control unit collects and records the electrical parameter data of the fan under normal operation conditions in segments during a certain initial stable operation time (such as several operating cycles), performs trend analysis and calculates the trend characteristic values of this stage. Then, based on these trend characteristic values, a stage-based weighted comprehensive evaluation is carried out to obtain the comprehensive degradation index of the initial stage, and the system uses this index as the initial normal operation benchmark value for subsequent comparison of the operation status.

[0053] In addition, on the basis of the stage-based comprehensive degradation index, further integrate factors such as the cumulative operation time of the fan, the change of current load, and the environmental temperature and humidity to form a more comprehensive multi-dimensional comprehensive degradation index; S035: Judge whether the fan needs to be replaced according to the stage-based comprehensive degradation index.

[0054] When the stage-based comprehensive degradation index or the multi-dimensional comprehensive degradation index exceeds the dynamically updated warning threshold, it is determined that the fan enters the obvious degradation state, and a maintenance warning signal is sent in advance to prompt the user to perform component replacement and maintenance in time.

[0055] The said S035: Judging whether the fan needs to be replaced according to the stage comprehensive degradation index further includes: When the stage comprehensive degradation index exceeds the warning threshold, control the fan to perform a short-time reverse purge operation once; When the stage comprehensive degradation index exceeds the warning threshold and the system determines that the fan enters an obvious degradation state, perform a short-time conventional reverse purge maintenance operation once. The fan runs in the reverse direction for about 3-5 seconds to actively remove the initial salt mist or deposits on the heat sink and the fan blades; After the short-time reverse purge is completed, collect the fan electrical parameters again; After the short purge is completed, the system automatically performs another real-time collection of the fan electrical parameters (such as current, speed, etc.) to obtain the latest fan operating status.

[0056] Calculate a new stage comprehensive degradation index according to the recollected fan electrical parameters; In this embodiment, after recalculating the stage comprehensive degradation index at this time, compare this index with the comprehensive degradation index before purging: If the decrease range of the new stage comprehensive degradation index exceeds the preset decrease range, restore to the normal detection state; If the stage comprehensive degradation index after purging is significantly reduced (such as the decrease range exceeds the preset 20%), it means that the fan degradation phenomenon partly stems from surface deposits and there is no serious internal damage. At this time, there is no need to replace immediately, only restore to the normal monitoring state and adjust the next index monitoring period; If the decrease range of the new stage comprehensive degradation index does not exceed the preset decrease value, perform a strong purge operation.

[0057] If the stage comprehensive degradation index decreases slightly after purging, judge that the short-time conventional purge effect is insufficient, and automatically perform a stronger secondary enhanced purge maintenance action.

[0058] S81: When it is detected that the fan is replaced and powered on for the first time, enter the automatic parameter calibration state; For example, when it is detected that the fan has never run, that is, the running time is 0, or the control unit detects the behavior of disconnecting and then reconnecting the fan interface, or the maintenance log records a fan replacement operation, etc., it indicates that the fan is replaced and powered on for the first time; S82: Load pulse width modulation signals with different duty cycles to drive the fan to run in turn, and collect the fan behavior characteristic data; This step dynamically loads signals with different duty cycles (such as 40%, 60%, and 80%) to drive the fan to run in sequence. Each duty cycle signal is a gear. Each gear runs for the same preset time. The following data is collected in real time during operation: the nonlinear relationship between the drive current and the duty cycle; the time required to start to a stable speed; the current fluctuation range and power factor of each gear; the speed rise slope; the degree of current drop lag; S83: Compare the collected fan behavior characteristic data with the behavior characteristic data of the original standard fan, the aged good fan, and the performance degraded fan; The original standard fan is an original fan with normal performance. The aged benign fan is a benign fan that has aged after being exposed to a humid environment. In specific implementation, individual data of fans that have been operating normally for a long time without any abnormalities can be obtained from the air-cooled fish collecting lights. For example, fans that have been operating for more than 100 hours and have never triggered a maintenance warning can be found. The operating parameters of these fans can be traced back to extract their current-speed curves, response time curves, etc. Although these fans have slight aging phenomena such as slightly increased current and slightly decreased speed, they are highly stable. Their behavioral characteristics can be classified as a benign aging model in this embodiment. This embodiment can collect behavioral characteristic data of such fans; Among them, performance-degraded fans refer to fans with high corrosion degradation or improper maintenance, such as fans with oxidation of brush blades and salt corrosion of power interface. The behavioral characteristic data of such models can be obtained when the aforementioned method is used to determine the accelerated degradation state of the fan; S84: Adjust operating parameters according to the comparison results.

[0059] Including: S841: if the comparison result shows that the operating characteristics of the current fan match the original standard fan, the default operating parameter configuration is adopted, and the energy-saving optimization strategy is started according to the current ambient temperature and load status; In this embodiment, if the comparison result shows that the operating characteristics of the current fan match the original standard fan, the default operating parameter configuration is restored and enabled, and the energy-saving optimization strategy is further started according to the current ambient temperature and load status. In the specific implementation process, the system adopts a fast startup mode, that is, a higher pulse width modulation duty cycle is directly applied during the fan startup phase. For example, the duty cycle can be increased to 70% to pull up to the target speed in the shortest time. At the same time, if the temperature of the LED module is in a low temperature or constant area, the system will dynamically lower the fan operating power to avoid unnecessary energy consumption. In addition, considering that the operating state of this type of fan is stable, the system will reduce the frequency of operating state monitoring and extend the evaluation period of the staged comprehensive degradation index to 6 hours to reduce the computing load. This type of fan can also be marked as a stable fan, which can be used as a behavioral template reference in the future to participate in the behavioral comparison modeling of other fans.

[0060] In this embodiment, if the comparison result shows that the operating characteristics of the current fan match those of a benign aging fan, a mild drive and medium-frequency monitoring operation strategy is executed. In this case, at the initial stage of fan startup, the system adopts a soft-start mechanism, sets the PWM duty cycle to a low level, for example, it can be reduced to 50%, and gradually increases to the target operating power within 5 seconds to avoid instantaneous current impact caused by bearing resistance or wet brushes. The system also actively limits the maximum operating power, such as setting the duty cycle upper limit to 85%, to prevent the fan from aging rapidly under high voltage or high load conditions. In terms of operation monitoring, the system sets the evaluation period of the phased comprehensive deterioration index to once every 2 hours and continuously compares it with the behavior curve at the initial calibration of the fan. Once the current behavior parameters of the fan deviate from the initial value by more than 20%, the system will automatically trigger a degradation warning prompt to notify the user to pay attention to the potential aging trend of the fan and prepare for spare part replacement.

[0061] In this embodiment, if the comparison result shows that the operating characteristics of the current fan match those of a performance-degraded fan, a power limit protection and intensive monitoring mechanism is immediately adopted. During the startup stage, the system limits the fan startup power to a low level, for example, the duty cycle of PWM can be limited to less than 40%, and the startup is completed through a phased soft-up method; during operation, the maximum duty cycle does not exceed 65% to reduce the thermal load and risk probability. The system also enables high-frequency deterioration monitoring, shortens the update period of the phased comprehensive deterioration index to 30 minutes, and introduces a short-cycle peak monitoring mechanism to capture the characteristics of abnormal current fluctuations. In addition, to prevent misjudgment caused by the fan's own faults or assembly deviations, the system sets a delay confirmation window period after the fan's first operation. If the behavior characteristics do not improve continuously within the 10-hour operation period, it will prompt to replace the fan. If such a fan is a newly installed part, the system can also prompt the user to check for assembly defects such as incorrect clamping or loose interfaces of the fan to ensure the integrity and safety of maintenance operations.
