Description

Technical Field

[0001] This invention relates to the field of structural detail technology, and in particular to a central beam of a freezer with embedded LED lights and heating wires. Background Technology

[0002] The technical field of refrigerator center beam structure involves longitudinal or transverse components used to connect and support the upper and lower structures of refrigeration and freezing equipment. Its core aspects include the design of the refrigerator's frame structure, material selection, and the configuration of its integrated functional components. This field improves the overall mechanical stability, thermal insulation performance, and functional integration of the refrigerator by optimizing the configuration of structural components. Methodologically, it mainly involves system integration design and manufacturing through integral component molding, functional module embedding, and optimized arrangement. A traditional refrigerator center beam refers to a metal or plastic profile component located at the front of the refrigerator body to support the door and prevent condensation in the door seams. This center beam typically uses external LED lights for illumination and embeds resistance heating wires inside the foamed insulation layer to prevent condensation. Each component is driven and outputs its function through an independent circuit system.

[0003] In existing technologies, both the lighting lamps and heating wires rely on independent circuit systems to achieve functional output. During structural layout, there is a lack of a quantitative identification mechanism for thermal interference areas. Component installation typically relies on pre-set, empirically determined locations, leading to potential overlap or overly close placement of LED light strips and heating wires. This can easily cause localized heat accumulation or condensation backflow, reducing lighting lifespan and anti-condensation efficiency. The internal thermal response state of the central beam is not systematically collected and analyzed, making it impossible to optimize the functional component layout based on the actual thermal field distribution. This results in poor heat dissipation paths, frequent thermal expansion and contraction, and impacts the mechanical stability of the encapsulation shell and slide rail structure. Regarding electrical connections, the electrical contact status of traditional sliding terminals relies on manual inspection or retrospective investigation after failure, lacking dynamic monitoring methods during power supply. This makes it easy to overlook slight fluctuations, and over long-term operation, potential electrical contact problems gradually accumulate, leading to issues such as intermittent disconnections and contact aging. There is no established feedback recording mechanism for structural response changes, making it impossible to quantify whether the self-locking structure is frequently triggered. Thermal deformation behavior is difficult to predict, posing a risk of unannounced structural displacement. These problems will be further exacerbated with increased integration of the central beam structure, severely affecting the overall performance stability and component lifespan of the refrigerator. Summary of the Invention

It compares the distance from the center point of the interval to the nearest boundary of the thermal insulation layer with the thermal insulation determination threshold, and divides it into two categories: thermal concentration area and buffer zone, to obtain the thermal zoning identification result. Based on the thermal zone identification results, the structural positioning submodule indexes and marks the corresponding positions of the thermal zones in the structural coordinate sequence.

The layout labeling submodule compares whether all the sections to which the layout structure belongs are located in the thermal buffer structure area based on the available space matching value, verifies the structure section number that meets the conditions, marks it as a layout completed state and generates a corresponding layout label, and obtains the layout completed identifier.

[0009] As a further aspect of the present invention, the electrical contact stability monitoring module includes: The location extraction submodule obtains the deployment completion identifier, extracts the spatial position number of the sliding contact power supply terminal in the structural section within the corresponding deployment section, arranges the terminal number according to the structural order, and generates the sliding contact terminal position sequence value. The current monitoring submodule records the instantaneous current data of the terminal during a continuous energizing cycle based on the position sequence value of the sliding terminal, extracts the maximum and minimum current values ​​of each terminal during the energizing cycle, calculates the corresponding difference as the current change amplitude, and obtains the current fluctuation amplitude value. The fluctuation control submodule calls the standard fluctuation threshold based on the current fluctuation amplitude value, compares whether the current change amplitude corresponding to each terminal is less than the standard fluctuation threshold, filters the corresponding terminal position numbers and arranges them in numerical order to generate a contact fluctuation control number set.

Combined with the analysis of the distance between the LED slide rail and the heating wire, spatial conflicts are avoided, enhancing the rationality of the layout. The thermal deformation of the guide rail is linked with the wall thickness data, recording the frequency of displacement response, and providing early warning of thermal deformation trends, ensuring the long-term stable operation of the structure. The entire process constructs a closed-loop path from thermal distribution identification, spatial arrangement, operation monitoring to response feedback, systematically improving the integration, thermal stability and functional reliability of the central beam structure.

[0022] This invention provides a refrigerator beam with embedded LED lights and heating wires, such as... Figure 1-2 The diagram shows a central beam of a freezer with embedded LED lights and heating wires. The system includes: The hot zone parameter acquisition module acquires the thermal response information of the reflective area of ​​the lighting cavity in the beam of the refrigerator with embedded LED lights and heating wires, as well as the installation location of the heating wires. It also acquires the voltage value returned by the temperature measuring device, converts it into temperature value according to the conversion relationship, and organizes the temperature value into a linear thermal distribution sequence according to the cavity structure sequence. By comparing the temperature difference trend between the difference points, it generates the temperature difference gradient distribution value. The reflective area of ​​the lighting cavity is a reflective film structure area set inside the lighting cavity of the refrigerator beam to enhance the light output efficiency of the LED. It is derived from PET reflective film or aluminum foil reflective sheet materials commonly used in refrigerator door frame lighting systems. The voltage value returned by the temperature measuring device is an analog electrical signal generated by the thermistors arranged inside the beam of the freezer, which is used to calculate the temperature through the resistance characteristics. The temperature gradient distribution value is a temperature and location correspondence sequence formed based on the temperature change trend of multiple cavity points, used to characterize the thermal change pattern inside the beam structure. The thermal conductivity zone identification module extracts the sections with continuous thermal changes based on the temperature difference gradient distribution value, and determines the distribution range of heat concentration area and buffer zone by combining the position of the insulation layer. At the same time, it marks the corresponding position index of the section in the structure and generates thermal conduction interference section labels. The thermal conduction interference section label is a section index information formed based on the temperature difference gradient analysis inside the cavity, used to identify the heat transfer status of the central beam at different locations; The component collaborative deployment module filters out structural sections within the deployment area that meet the thermal buffering conditions based on the thermal conduction interference section labels. It retrieves the length data of the LED light strip slide rail component and the heating wire installation interval parameters to analyze whether there is spatial interference conflict between the two components in the structural deployment. If the length range of the LED slide rail does not overlap with the heating wire installation area and the LED slide rail is entirely within the thermal buffering structural section, the deployment structure is classified as the deployment completed state, and a deployment completed identifier is generated. The heating wire installation interval parameter is the data on the spacing of the heating wires in the heating cavity of the central beam, which comes from the structural design requirements of the serpentine heating wire installation path; The layout completion marker is a structural layout verification status mark formed based on the condition that the LED light strip slide rail and heating wire layout do not interfere with each other. It is used to indicate that the current layout structure meets the spatial layout conditions. Based on the deployment completion marker, the electrical contact stability monitoring module extracts the position of the sliding contact power supply terminal in the current deployment section, records the current fluctuation data during power supply, calculates the current change amplitude of the terminal in the continuous power-on cycle, and summarizes the terminal positions with current change amplitudes lower than the standard fluctuation threshold to generate a contact fluctuation control number set. The sliding contact power supply terminal is the electrical connection point formed between the LED light strip and the power supply line through a sliding contact method, which is derived from the sliding contact power supply structure commonly used in refrigerator lighting systems; The current variation amplitude is a quantitative value of the current fluctuation range of the sliding electrode within a fixed energizing cycle, used to evaluate the electrical stability of the sliding contact power supply connection; The contact fluctuation control number set is a sequence of terminal numbers selected based on the fluctuation of the power supply terminals during power-on, used to identify terminal points where electrical fluctuations are within a set range; The slide rail self-locking linkage module calls the contact fluctuation control number set and checks the wall thickness record of the encapsulated shell in the corresponding position structure to determine whether the area guide rail has displacement due to thermal changes, and monitors the number of triggers of the self-locking structure. If the trigger frequency exceeds the set conditions, the area is marked as a response sensitive section, and the displacement response frequency of the beam light track structure in the refrigerator is generated. The wall thickness record of the enclosure is a collection of wall thickness information of the differential structural sections of the central beam enclosure, which is used to determine the guide rail deformation caused by heat in the enclosure; The number of times the self-locking structure is triggered is the action count value of the LED slide rail section deformation response limit component within the operating cycle, which is obtained based on the action record of the shape memory component or the mechanical limit structure. The displacement response frequency of the light track structure in the refrigerated display case is a statistical index of displacement response based on the action record of the self-locking structure, used to characterize the frequency of displacement behavior of the light track section under thermal environment.

[0023] The temperature gradient distribution values ​​include temperature difference trends, linear heat distribution sequences, and structural sequence information. The heat conduction interference section labels include heat concentration area distribution, buffer zone distribution, and structural location index. The deployment completion identifier includes the LED slide rail length range, heating wire installation area location, and heat buffer structure section status. The contact fluctuation control number set includes current change amplitude, current fluctuation data, and terminal location number. The cold cabinet beam light rail structure displacement response frequency includes encapsulation shell wall thickness records, guide rail thermal displacement status, and self-locking structure trigger count.

[0024] Specifically, such as Figure 2 , 3 As shown, the thermal parameter acquisition module includes: The voltage reading submodule collects the voltage values ​​returned by the temperature measuring device, and classifies the voltage values ​​according to the spatial sequence of the reflective area of ​​the illumination cavity and the heating wire installation location in the cavity structure. It then establishes a voltage data set corresponding to the sequence of the illumination cavity structure and obtains the sequence voltage set. When acquiring voltage data from the temperature measuring device, the spatial location corresponding to each voltage channel must first be identified. The temperature measuring device converts local temperature changes into voltage signals using a thermistor, such as a thermocouple or thermistor. The acquisition system is set with 13 temperature measuring points, including 8 points in the reflector area and 5 points in the heating wire area. Voltage value readings are processed using a polling mechanism for channel switching. The controller sequentially starts the ADC module, with each channel having a sampling period of 100 milliseconds. After voltage value acquisition, it enters the buffer and is then labeled and classified according to the point numbers marked on the cavity structure drawing, from P1 to P13. If channel 3 acquires a voltage of 0.76V in the current period, this voltage value is classified as P3, corresponding to the middle section of the heating wire in the cavity, thus completing the spatial binding between channel 3 and structural point P3. After all channels are acquired, a set of voltage data with a clear order is formed, such as 0.81V, 0.78V, 0.76V, 0.79V, 0.83V, etc., and arranged according to the location order, thus generating a set of voltage sequences corresponding to the structural sequence. This set reflects the voltage distribution in each key area of ​​the illumination cavity structure, providing a basis for subsequent temperature conversion and analysis.

[0025] The temperature conversion submodule is based on the set of sequence voltages. It calls the voltage-temperature conversion relationship set by the temperature measuring device, converts the voltage values ​​of the points in the set, and rearranges the converted temperature values ​​according to the structure sequence of the central beam lighting cavity to obtain a linear temperature sequence. Upon receiving the voltage sequence arranged in the structural order, the system invokes a preset conversion relationship between voltage and temperature. This relationship was obtained through early calibration experiments, such as reading known temperature points corresponding to different voltage values ​​from a standard temperature source to establish a one-to-one data set. Based on measurement results showing 0.5V corresponds to 30°C and 1.0V corresponds to 80°C, a linear conversion relationship is established to convert different voltage values ​​into temperature data. When the voltage corresponding to structural point P3 is 0.76V, the converted temperature is 56°C. The same conversion process is performed on all points to obtain a set of temperature value sequences consistent with the structural order, such as 56°C, 59°C, 63°C, 61°C, 65°C, etc. This sequence is mapped and organized with the original point numbers to ensure that the temperature values ​​accurately reflect the temperature state of each physical spatial point. During the conversion process, the slope parameter and bias parameter are derived from experimental fitting results and are based on the physical characteristics of the temperature measuring device. The voltage-to-temperature conversion process does not require complex formulas or external algorithms; it relies solely on table lookups or linear interpolation of prior data. The converted temperature series possesses an accurate spatial distribution, serving as the input basis for subsequent temperature difference analysis.

[0026] The temperature difference distribution submodule calculates the temperature difference between adjacent points based on the linear temperature sequence, takes the temperature difference sequence between consecutive points as input data, compares the trend of numerical change, identifies the continuous segment of numerical change range, and obtains the temperature difference gradient distribution value. After receiving the temperature sequence, the temperature changes between adjacent points need to be analyzed one by one. The temperature difference between each point and its successor is compared sequentially. For example, if the temperatures of points 1 and 2 are 56°C and 59°C respectively, the difference is 3°C. The process continues with the next point pair; for example, the difference between 59°C and 63°C is 4°C. This process is repeated to obtain a set of differences between multiple consecutive points. These differences are used to identify potential temperature distribution variation areas within the illumination cavity. The identification method involves setting a temperature difference threshold, such as 2.5°C. When the temperature change between two consecutive points is not less than this threshold, it is considered a significant change. If multiple consecutive differences exceed this threshold, it indicates a rapid temperature rise or fall trend within that spatial segment. For example, if the temperature differences of three consecutive points are 3.6°C, 4.0°C, and 2.9°C, this segment is identified as a high-temperature gradient region, with the starting and ending points corresponding to structural regions numbered 3 to 5 within the cavity, respectively. Record the start and end point numbers, section lengths, and average temperature differences of these sections to form gradient distribution information, such as start point P3, end point P5, section length 3, and average temperature difference 3.5°C. All sections meeting the criteria form a temperature gradient distribution list, providing a basis for subsequent temperature control strategies and heating zone distribution optimization.

[0027] Specifically, such as Figure 2 , 4 As shown, the thermal zoning identification module includes: The thermal variation extraction submodule obtains the temperature difference gradient distribution value, filters the segments where the temperature difference between consecutive points is greater than the thermal variation threshold, merges adjacent points that meet the thermal variation conditions into consecutive segments, arranges the segments according to the point sequence and marks the start and end positions, and generates continuous thermal variation interval values. After receiving the temperature gradient distribution values, the temperature difference data between each structural point is first read, and the data is reconfirmed according to the order of the structural points. During the filtering operation, it is determined whether the temperature difference between each adjacent point exceeds the preset thermal fluctuation threshold. The threshold is set according to the thermal conductivity stability requirements of the device, and the recommended value is between 2.5°C and 3.0°C, which can be adjusted to 2.8°C according to the on-site test conditions. The judgment process is as follows: starting from the first temperature difference value, it is directly compared with the threshold. If the temperature difference of a point is 3.2°C, exceeding the threshold, it is marked as a point that meets the condition. The comparison continues with the next point difference. If multiple consecutive points meet the condition, such as differences of 3.7°C and 3.4°C, these points can be merged into a group of continuous thermal fluctuation segments. During merging, all consecutive points that meet the condition must be gathered in sequence. If the temperature difference of a certain point drops to 2.1°C, below the threshold, the merging is interrupted, forming a complete segment. This process is repeated for the entire set of temperature difference data, extracting all continuous regions that meet the criteria, and recording the start and end point numbers of each region. For example, segments P3 to P5 and P8 to P10 represent two continuous thermal variation segments, respectively. Finally, all thermal variation segments are organized in order of their points to form a structurally sequenced continuous thermal variation interval value, providing a clear labeling basis for subsequent structural zoning identification.

[0028] The thermal insulation determination submodule uses the continuous thermal variation interval value to call the thermal insulation layer location information in the structure, judges the positional relationship between the interval and the thermal insulation layer, compares the distance from the center point of the interval to the nearest boundary of the thermal insulation layer with the thermal insulation determination threshold, and divides it into two categories: thermal concentration area and buffer zone, to obtain the thermal zoning identification result. After obtaining the values ​​for the continuous thermal variation range, the start and end position data of the insulation layer in the structural configuration are called to determine the spatial distance for each thermal variation segment. The determination process is as follows: First, the center point of each segment is extracted. The center point is defined as the median of the position between the start and end points of the segment. If the segment is P3 to P5, then the center point is P4. Then, the distances to both sides of the center point and the insulation layer position are calculated, and the smaller distance to the start and end points of the insulation layer is selected as the effective distance. Taking the center point P4 as an example, if the insulation layer range is P6 to P9, the distance between P4 and P6 is 2 points, and the distance between P4 and P9 is 5 points, then the minimum distance is 2. Next, this distance is compared with the set insulation judgment threshold, which is set with reference to the thermal diffusion effect of the insulation material, generally 3 points. If the actual minimum distance is less than 3, the segment is determined to be a heat concentration area; otherwise, it is a buffer zone. When performing this operation, all thermal variation segments need to be judged one by one. After completion, the starting point, ending point, center point and minimum distance value of each segment are recorded. At the same time, the judgment result, i.e. thermal concentration or buffer category, is marked to form a complete thermal zoning identification result set, which is arranged in ascending order by point number to facilitate subsequent positioning operations.

[0029] Based on the thermal zone identification results, the structural positioning submodule indexes and marks the corresponding positions of the thermal zones in the structural coordinate sequence. After matching the index values ​​with the original point numbers, it establishes a segment index mapping sequence and combines the thermal zone attribute information to organize it into label data to obtain the thermal conduction interference segment labels. After receiving the thermal zone identification results, coordinate index mapping is performed on each segment one by one. The execution process is as follows: First, based on the mapping relationship between the point number and coordinate value in the structural drawings, the actual position values ​​of the start and end points of the thermal zone in the structural coordinate sequence are obtained. For example, point P4 corresponds to position 12 on the X-axis, and P6 corresponds to position 18. Then, this coordinate information is bound to the start and end point numbers of the thermal zone, forming a dual identifier between structural coordinates and physical points. Next, combined with the thermal zone attribute results, each segment is assigned a thermal zone attribute label, with label types divided into two categories: thermal concentration area and buffer zone. If P4 to P6 are determined to be thermal concentration areas, they are marked in the index sequence as: points P4 to P6, positions 12 to 18, category: thermal concentration. All thermal zone segments are organized into a set of label data lists according to the point number order. Each record contains the original point number, coordinate position range, and thermal zone attribute information, ultimately forming a set of heat conduction interference segment labels, providing an accurate data identification foundation for subsequent structural monitoring, thermal management control, and other applications.

[0030] Specifically, such as Figure 2 , 5 As shown, the component collaborative deployment module includes: The heat buffer screening submodule obtains the heat conduction interference section label, filters the structural section data that is not included in the interference section in the deployment area, judges the continuity of the structural section with the heat buffer judgment threshold, removes structural sections with insufficient length, sorts them in spatial order, and generates heat buffer structural interval values. Upon receiving the label for the heat conduction interference section, the system sequentially iterates through all point numbers within the layout area of ​​the structure. First, all structural points falling within the heat conduction interference section are eliminated, creating a set of candidate structural segments not within the interference section. Then, each structural segment in this set is arranged in order of point number to form a continuous segment. The system then determines whether the actual length of each continuous structural segment meets the thermal buffer threshold. The threshold is set based on the thermal stability requirements of the LED light strip, and a value of no less than 100mm is recommended to ensure sufficient length for the structural segment. The determination method is to count the number of points between the first and last points of the continuous structural segment, and then multiply this number by the standard spacing between structural points. For example, a structural segment composed of points P12 to P15, with a point spacing of 25mm, has a length of 75mm, which is below the 100mm threshold and should be eliminated from subsequent structural components. If another segment, numbered P20 to P25, has a length of 150mm, it is retained. All structural segments that meet the threshold conditions are reorganized and sorted, and numbered according to the order of structural points to ensure that the output thermal buffer structural interval data has spatial continuity and structural independence. Finally, a set of structural segments with sufficient thermal buffer characteristics is formed as the basis data for subsequent deployment analysis.

[0031] The interference verification submodule, based on the thermal buffer structure interval value, calls the LED light strip slide rail assembly length data and heating wire installation interval parameters to determine whether the end position of the LED slide rail assembly falls within the heating wire installation interval, filters out layout structures with overlapping interference, and generates a space matching value that can be deployed. After receiving the interval values ​​of the heat buffer structure, the actual length parameters of the LED slide rail assembly and the interval data of the heating wire installation area are retrieved one by one, and the end position of each heat buffer structure segment is compared sequentially. First, the starting coordinates of each structure segment are read, and the corresponding distance is extended towards the end point according to the length of the LED slide rail assembly. Then, it is confirmed whether the extended end point falls within the heating wire laying area. The heating wire laying interval is a setting item in the structure installation parameters. For example, the heating wire is set to be one wire every 100mm, extending from 300mm to 700mm. If the starting point of the heat buffer structure segment is 650mm and the length of the LED slide rail assembly is 120mm, then the extended end point is 770mm. This point falls within the heating wire laying interval and should be considered an interference segment and removed from the candidate layout structure. If another structure segment starts at 150mm and extends to 270mm at the end point, without overlapping with the heating wire range, then it is a valid layout segment. After performing the above judgment on each of the structural segments, all structural segments with endpoints falling into the heating wire area are filtered out, and the final output is a set of space matching values ​​that can be deployed, which serves as qualified input data for deployment annotation.

[0032] The layout labeling submodule compares the available space matching value to see if all the sections to which the layout structure belongs are located in the hot buffer structure area, verifies the structure section number that meets the conditions, marks it as layout completed and generates the corresponding layout label, and obtains the layout completion identifier. Based on the deployable space matching value, the allocation verification operation of each deployment segment is performed sequentially by comparing the numbering data of each structural segment to be deployed. The start and end numbers of the current deployment segment are read, and each record in the hot buffer structural segment is compared. If both the start and end numbers of a deployment segment are within the range of the start and end numbers of a hot buffer structural segment, then the segment is considered a valid deployment segment. In specific operations, if the deployment segment numbers are P22 to P28, and the hot buffer segment numbers are P20 to P30, then the deployment segment completely falls within the hot buffer segment, meeting the deployment conditions. It is recorded as deployed and marked with a deployment tag. If the deployment segment is P28 to P35, and the end point P35 exceeds the end point P30 of the buffer segment, then the deployment conditions are not met, and this structural segment is ignored. All verified structural segment numbers are uniformly marked with a status and a deployment label is generated. The label contains information such as the structural segment number, deployment status, and the corresponding hot buffer structural segment number. Once all tags are recorded, a deployment completion identifier dataset is created and provided to the deployment system as an index for confirmed deployment structures.

[0033] Specifically, such as Figure 2 , 6 As shown, the electrical contact stability monitoring module includes: The location extraction submodule obtains the deployment completion marker, extracts the spatial position number of the sliding contact power supply terminal in the structural section within the corresponding deployment section, arranges the terminal number according to the structural order, and generates the sliding contact terminal position sequence value. After obtaining the deployment completion marker, the process begins to traverse all structural segments marked as deployed. Each structural segment contains a fixed numbered interval. The actual installation positions of each sliding contact power supply terminal within this interval are extracted, and the corresponding number of each terminal in the linear structural path is recorded. The numbering is set according to the direction from the start to the end of the structure, with each 100mm interval representing a numbering interval. After extraction, all terminal numbers are uniformly organized and sorted in ascending order to ensure that the numbering order is consistent with the physical structural deployment direction. Taking actual deployment data as an example, if structural segments S01 to S04 contain terminal installation positions with corresponding numbers of 360, 380, 410, 430, 450, 480, and 510, the sorted sliding contact terminal position sequence is 360, 380, 410, 430, 450, 480, and 510. This sequence is used for terminal data sampling and identification in the subsequent monitoring phase.

[0034] The current monitoring submodule records the instantaneous current data of the terminal during a continuous energizing cycle based on the position sequence value of the sliding contact terminal. It extracts the maximum and minimum current values ​​of each terminal during the energizing cycle, calculates the corresponding difference as the current change amplitude, and obtains the current fluctuation amplitude value. After receiving the position sequence of the sliding contact terminals, current sampling is performed sequentially for each numbered position. The sampling period is set to once every 50ms, and the total sampling time is no less than 20s to ensure coverage of typical operating current fluctuation cycles. Multiple instantaneous current values ​​are continuously recorded for each terminal during energization. The maximum and minimum values ​​are extracted, and the difference between them represents the current fluctuation amplitude of that terminal. For example, terminal number 450 detects a maximum current of 7.8A and a minimum of 6.3A during one energization cycle, with a current fluctuation amplitude of 1.5A. This value represents the overall amplitude of the current change of the terminal during that energization cycle. The above recording and calculation process is repeated for all terminals to generate a complete set of current fluctuation amplitude data, which serves as the data basis for the next step of fluctuation screening and control.

[0035] The fluctuation control submodule calls the standard fluctuation threshold based on the current fluctuation amplitude value, compares whether the current change amplitude corresponding to each terminal is less than the standard fluctuation threshold, filters the corresponding terminal position numbers and arranges them in order of number to generate a contact fluctuation control number set. After reading the current fluctuation amplitude data, the set standard fluctuation threshold is used to compare and judge the current change amplitude of each terminal. The standard fluctuation threshold is set based on the maximum allowable fluctuation amplitude of the power supply system. If the maximum allowable fluctuation of the power supply system is set to 0.8A, then all terminals with current change amplitudes less than this value are considered to have controllable fluctuations. For example, if the current change amplitude of terminal number 430 is 0.65A, it meets the judgment condition, and terminal number 430 is included in the fluctuation control terminal set. If the fluctuation amplitude of terminal number 480 is 1.25A, it exceeds the threshold and is not retained. All terminal numbers that meet the screening conditions are then arranged sequentially to form a contact fluctuation control number set, which serves as the basis for subsequent analysis and control.

[0036] Specifically, such as Figure 2 , 7 As shown, the slide rail self-locking linkage module includes: The wall thickness inspection submodule calls the contact fluctuation control number set, extracts the wall thickness record of the encapsulated shell in the corresponding position structure, obtains the wall thickness difference between adjacent measurement points and performs normalization calculation, compares the normalized wall thickness difference with the set structural wall thickness stability threshold, filters the number positions where the difference exceeds the threshold, and generates a wall thickness anomaly number set. Based on the contact fluctuation control number set, the wall thickness data of the encapsulation shell is extracted for the structural segment corresponding to each number position. In the actual testing scenario, each number corresponds to multiple wall thickness measurement points. To obtain the local structural uniformity, the wall thickness difference between two adjacent measurement points needs to be calculated. The calculation method is to subtract the smaller value from the larger value to obtain the absolute difference. After obtaining the difference, the difference is divided by the standard wall thickness value of the corresponding position in the design structure to obtain the normalized wall thickness difference. The normalized difference is used to eliminate the inconsistency of dimensions caused by different overall thickness settings, ensuring the comparability of wall thickness fluctuations between different number positions. Under each number position, the maximum value of the normalized difference of multiple adjacent measurement points is taken for subsequent judgment. Taking number 450 as an example, if the wall thicknesses detected at the three measurement points of the encapsulation shell at this location are 1.85mm, 1.90mm, and 1.83mm respectively, and the standard structural wall thickness is 1.80mm, then the normalized difference between adjacent points is approximately 0.028 and 0.039, of which 0.039 is taken as the final judgment criterion. The judgment process uses a structural wall thickness stability threshold for comparison. This threshold is set based on the structure's forming precision and mechanical performance requirements, typically ranging from 0.02 to 0.04. If the threshold is set to 0.03, then the normalized difference for number 450 exceeds this threshold, indicating an abnormal wall thickness location. All numbers are sequentially subjected to normalized difference calculation and threshold comparison. After filtering out all numbers with differences exceeding the limit, a set of abnormal wall thickness numbers is formed. This set serves as the input data source for subsequent structural thermal deformation analysis.

[0037] The displacement judgment submodule extracts the thermal change parameters of the guide rail structure at the corresponding number position based on the set of abnormal wall thickness numbers, detects the offset value of the structural center coordinate of the guide rail in a continuous time period, determines whether the offset direction is consistent with the thermal change direction, filters the position numbers that meet the offset conditions, and obtains the set of thermally induced guide rail offset numbers. After reading the set of wall thickness anomaly numbers, thermal response analysis is performed on the guide rail structure at each number location. Extracted thermal change parameters include the ambient temperature difference, the coefficient of thermal expansion of the guide rail material, and the actual length of the guide rail segment corresponding to that number location. The potential displacement trend of the guide rail under this environmental change is estimated through thermal expansion phenomena. Displacement determination is not based on precise calculation of the theoretical displacement, but rather on whether the theoretical direction matches the actual structural center coordinate offset direction. For example, at position number 450, if the guide rail length is 700mm, the ambient temperature difference is 18K, the guide rail material is aluminum alloy with a coefficient of thermal expansion of 23 micrometers per meter per Kelvin, then the theoretical offset direction is outward expansion along the guide rail's expansion direction. In this case, the structural center offset direction at this location within a 24-hour continuous period is extracted from the sensor and compared with the theoretical thermally induced direction. If the directions match, the number is recorded as the thermally induced guide rail offset number; if the directions are opposite or unclear, it is not recorded. After comparing the offset directions of all wall thickness anomaly numbers in sequence, all numbers that meet the consistency conditions are summarized to generate a set of thermally induced guide rail offset numbers, which are then used by the frequency monitoring module to further identify the persistence and recurrence of structural anomaly activities.

[0038] The frequency monitoring submodule calls the thermally induced guide rail offset number set to monitor the number of times the self-locking structure in the corresponding structure is triggered, counts the total number of triggers and the trigger frequency value of the number position in a continuous time period, compares the frequency value with the set structural trigger response threshold, filters the position numbers whose frequency exceeds the threshold, and establishes the displacement response frequency of the beam light rail structure in the freezer. After obtaining the set of thermally induced guide rail offset numbers, the triggering behavior of the self-locking structure is continuously monitored within a specified observation period according to the structural area corresponding to the number. The cumulative number of triggers of the self-locking device at each number location is recorded, and the triggering frequency per unit time is calculated. The monitoring period is set to 24 hours, meaning the total number of triggers is counted within a daily cycle, and the average triggering frequency per hour is calculated. Taking number 450 as an example, if the number of self-locking structure triggers detected in 24 hours is 13, then the triggering frequency at this location is approximately 0.54 times per hour. To determine whether it is an abnormal response structure, a set structural trigger response frequency threshold is called for comparison. The threshold is set based on the structural fatigue tolerance standard and system response capability, with a common value range of 0.4 to 0.6 times per hour. If the threshold is set to 0.5 times per hour, then number 450's frequency exceeds this value and is recorded as an abnormal frequency structure number. After comparing the frequency value with the threshold for all number locations, the positions with frequencies higher than the response threshold are compiled into a set of displacement response frequencies for the refrigerated cabinet beam light rail structure, serving as an important source of basic data for subsequent structural condition assessment.
