Description

Technical Field

[0001] This invention relates to the field of electrical safety tool testing technology, and more specifically, to a safety monitoring system for insulating poles based on full-dimensional environmental perception. Background Technology

[0002] Insulating rods are commonly used safety tools in power maintenance, distribution operation and maintenance, and live-line work. In automated inspection stations, visual sampling, surface temperature sampling, and posture sampling of the current inspection area of ​​the insulating rod are required to provide basic data for condition judgment or defect identification. After entering the inspection station, the insulating rod typically undergoes processes such as transfer, support, clamping, indexing rotation, and axial stopping.

[0003] In actual testing, the current sampling is not always in a stable state. After the insulating rod is transferred from the warehouse or temporary storage area to the testing area, the surface temperature of the rod may be lower than the air temperature in the testing area. Under high humidity conditions, it is easy to approach the dew point temperature, resulting in the risk of condensation. There may also be scattered light, local glare, dust obstruction, and short-term airflow disturbance in the testing area. After the clamping mechanism completes gripping, zeroing, or indexing positioning, the rod may also experience short-term vibration and posture swing. These factors will cause fluctuations in image brightness, grayscale, sharpness, surface temperature, and posture information, resulting in distortion or instability in the single sampling results.

[0004] Existing detection systems typically record environmental parameters or directly output detection data after completing routine sampling, lacking a joint determination mechanism to determine the usability of the current sample. Especially in stations with fast automated detection cycles, if the stability conditions of the current sample are not first determined, invalid samples affected by light fluctuations, dust obstruction, condensation risk, vibration, or attitude drift may still enter the detection data processing flow, leading to misinterpretation of image features, distortion of surface temperature interpretation, inconsistent retest results, and a lack of environmental condition traceability in the detection records.

[0005] Therefore, there is a need in the field for a safety monitoring system that can determine the validity of the current sampling at an automatic detection station for insulating rods and restore the sampling conditions when the sampling is invalid. Summary of the Invention

[0006] To overcome the aforementioned deficiencies in the prior art, this invention provides a safety monitoring system for insulating poles based on full-dimensional environmental perception. It establishes a sampling validity admission mechanism indexed by the sampling window in the automatic detection station of the insulating pole. By synchronously receiving environmental sampling values, pole status sampling values, and reference channel responses, it generates monitoring validity parameters characterizing the current sampling availability and prevents disturbed sampling from entering the detection data processing flow before validity confirmation. Simultaneously, it invokes the corresponding station adjustment or resampling action based on the invalidation reason and writes the sampling window, environmental status, and adjustment record into the environmental reference field, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An insulated rod safety monitoring system based on omni-dimensional environmental perception includes an insulated rod detection station, a safety monitoring center, and a station adjustment and execution unit. The insulated rod detection station is equipped with an omni-dimensional environmental perception network and a synchronous reference calibration unit. The omni-dimensional environmental perception network includes an environmental perception subunit and a state perception subunit. The environmental perception subunit is used to collect the temperature, humidity, light intensity, and dust concentration of the detection environment, while the state perception subunit is used to collect the vibration, attitude, surface temperature, current axial position, and current circumferential position of the insulated rod. The synchronous reference calibration unit is used to output a reference channel response within the current sampling window. The safety monitoring center divides the sampling window according to a preset sampling period, and receives the sampling values ​​from the environmental perception subunit, the sampling values ​​from the state perception subunit, and the reference channel response output by the synchronous reference calibration unit within the same sampling window. It generates monitoring validity parameters including illumination stability, dust obstruction, dew point margin, vibration amplitude, and attitude drift, and determines whether the current sampling meets the validity conditions based on the monitoring validity parameters. When the current sampling meets the validity conditions, it outputs valid monitoring data and environmental reference fields; when the current sampling does not meet the validity conditions, it outputs a workstation adjustment command or a resampling command according to the reason for invalidity.

[0008] As a further embodiment of the present invention, the environmental sensing subunit includes a temperature and humidity sampling module, a light sampling module, and a dust sampling module; the state sensing subunit includes a vibration sampling module, a position sampling module, an attitude sampling module, and a surface temperature sampling module; each sampling module is uniformly connected to a sampling clock interface so that the safety monitoring center receives the corresponding sampling values ​​within the same sampling window.

[0009] As a further embodiment of the present invention, the synchronous reference calibration unit includes a visual reference calibration component, a temperature and humidity coupling reference, and a mechanical stability reference point; the visual reference calibration component includes a grayscale reference area and a texture reference area disposed within the detection field of view; the mechanical stability reference point includes a vibration sampling point and an attitude sampling point disposed at the clamping end of the insulating rod.

[0010] As a further aspect of the present invention, the safety monitoring center generates illumination stability based on the brightness and grayscale changes of the visual reference calibration component within the current sampling window, generates dust obstruction based on the dust concentration and the clarity changes of the visual reference calibration component, generates dew point margin based on the temperature difference between the surface temperature of the insulating rod and the dew point temperature of the detection environment, generates vibration amplitude based on vibration sampling values, and generates attitude drift based on attitude sampling values.

[0011] As a further aspect of the present invention, the safety monitoring center divides the current sampling into valid, invalid samples to be adjusted, and invalid samples to be resampled. When the light stability, dust cover, dew point margin, vibration amplitude, and attitude drift all meet the preset validity conditions, the current sampling is classified as valid. When the light stability, dust cover, or dew point margin does not meet the preset validity conditions, but the vibration amplitude and attitude drift meet the preset validity conditions, the current sampling is classified as invalid samples to be adjusted. When the vibration amplitude or attitude drift does not meet the preset validity conditions, the current sampling is classified as invalid samples to be resampled.

[0012] As a further aspect of the present invention, the safety monitoring center outputs a supplementary lighting command or a shading command when the illumination stability does not meet the preset validity conditions, outputs a purging command when the dust obstruction does not meet the preset validity conditions, outputs a dehumidification command or a static setting command when the dew point margin does not meet the preset validity conditions, and outputs a reset command or a resampling command when the vibration amplitude or attitude drift does not meet the preset validity conditions. When the dew point margin does not meet the preset validity conditions and the vibration amplitude or attitude drift does not meet the preset validity conditions at the same time, mechanical stability failure is used as the priority classification criterion, the current sampling is maintained as invalid and awaits resampling, and a composite processing command is generated. The safety monitoring center first controls the workstation adjustment execution unit to perform a mechanical recovery action, and after the vibration amplitude and attitude drift meet the preset validity conditions, it then controls the workstation adjustment execution unit to perform a temperature and humidity recovery action.

[0013] As a further aspect of the present invention, the safety monitoring center confirms the current sampling as valid when the preset validity conditions are met in three consecutive sampling windows, and maintains the current sampling as invalid and outputs a workstation adjustment command or a resampling command when the preset validity conditions are not met in any sampling window.

[0014] As a further aspect of the present invention, the effective monitoring data includes visual monitoring feature data and status monitoring feature data after reference channel response verification; the environmental reference fields include sampling window marker, environmental status marker, current environmental parameter record and adjustment record fields; the status monitoring feature data includes current axial position, current circumferential position, attitude value and surface temperature value.

[0015] As a further embodiment of the present invention, the workstation adjustment execution unit includes a supplementary lighting and shading component, a purging component, a dehumidification component, a static control component, and a reset and re-mining control component. The safety monitoring center calls the corresponding component to execute the workstation adjustment action or the re-mining action according to the invalidation reason.

[0016] As a further aspect of the present invention, the environmental sensing subunit further includes a gas sampling module, which is used to collect at least one of ozone parameters, volatile organic compound parameters, and residual cleaning gas parameters inside the detection enclosure; the safety monitoring center writes the gas sampling values ​​into the current environmental parameter record.

[0017] The technical effects and advantages of the safety monitoring system for insulating poles based on full-dimensional environmental perception of this invention are as follows: This invention uses environmental sampling values, state sampling values, and reference channel responses as the criteria for determining the current sampling within the same sampling window, and generates monitoring validity parameters such as illumination stability, dust obstruction, dew point margin, vibration amplitude, and attitude drift. This allows the safety monitoring center to determine whether the current sampling meets the validity conditions before the detection data is output, thereby reducing invalid samples affected by illumination fluctuations, dust obstruction, condensation risks, vibration, and attitude drift from entering the detection data processing flow.

[0018] This invention outputs supplemental lighting, shading, purging, dehumidification, settling, reset, or resampling commands for different invalidation reasons. It outputs valid monitoring data and environmental reference fields only when the preset validity conditions are met for three consecutive sampling windows. This ensures that the output results have clear sources of sampling windows, environmental conditions, and adjustment records, thereby improving the consistency, stability, and traceability of the test results.

[0019] Figure 1 This is a schematic diagram of the detection station and overall structure of an insulating rod safety monitoring system based on full-dimensional environmental perception, according to the present invention.

[0020] Figure 2 This is a schematic diagram of the current sampling validity determination and workstation adjustment process of the present invention. Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1 like Figure 1As shown, this embodiment is applied to the automatic inspection station for insulating rods. The insulating rod to be inspected is an insulating operating rod used in scenarios with a rated operating voltage of 10kV to 35kV. The rod has a total length of 1580mm and an outer diameter of 32mm. The front end is equipped with an end working head connector and a metal sleeve, the middle is the insulating working section of the rod body, and the rear is equipped with an inter-section connector, a hand guard limiter, a hand grip, and a tail end sealing piece. When the insulating rod is sent into the inspection area by the transfer mechanism, the surface of the rod may be covered with dust, and the temperature of the rod may be lower than the air temperature of the inspection area. After the clamping mechanism completes the gripping and zero-position calibration, there may be short-term vibration and posture swing. To avoid the above factors from causing distortion in the image clarity, surface temperature interpretation, and posture consistency of the current sample, this embodiment, after the insulating rod is supported and clamped, first determines whether the current sampling meets the validity conditions, and then decides to output valid monitoring data or call the station adjustment execution unit to restore the sampling conditions.

[0023] After the insulating rod enters the detection area, it first rests on two sets of positioning supports. These supports are spaced apart along the axial direction of the rod to hold it in place and limit radial runout. Then, a clamping rotating component holds the insulating rod in the handheld area, completing the circumferential zero-position calibration. The clamping rotating component includes insulating jaws, a servo rotary drive, and an angle encoder. The insulating jaws are lined with a polytetrafluoroethylene layer, and the clamping force is set to 190N. The servo rotary drive drives the insulating rod to rotate in 45° increments, creating eight detection orientations on the outer circumference of the rod. The angle encoder has a resolution of 0.1° and outputs the current circumferential position.

[0024] The detection head is mounted on the axial movement assembly. The detection head includes an image acquisition component and a surface temperature sampling module. The image acquisition component acquires image data of the insulating rod surface within the current detection field of view, while the surface temperature sampling module acquires the surface temperature of the area being measured. The image data is used to generate image edge features, surface texture features, and grayscale distribution features. The axial movement assembly includes an axial guide rail, a slide table, a drive motor, and a displacement encoder. The displacement encoder has a resolution of 0.5 mm and is used to output the current axial position. The detection enclosure closes after the insulating rod is clamped and axially stopped, isolating the detection area from external scattered light, dust, and transient airflow. A sensor mounting frame is installed inside the detection enclosure, and a purge channel and a dehumidification circulation channel are located at the bottom of the enclosure. A supplementary lighting and light-shielding component mounting position is located on the side of the enclosure.

[0025] Once the detection enclosure is closed, the omni-dimensional environmental perception network and the synchronous reference calibration unit enter the current sampling preparation state. The omni-dimensional environmental perception network includes an environmental perception subunit and a state perception subunit. The environmental perception subunit is used to collect the temperature, humidity, light intensity, and dust concentration of the detection environment. Specifically, the temperature and humidity sampling module is located at the top center of the detection enclosure to collect the air temperature and relative humidity of the detection area; the light intensity sampling module is located at the edge of the detection field of view to collect the illuminance of the current detection area; and the dust intensity sampling module is located at the return air position at the bottom of the enclosure to collect the suspended dust concentration of the detection area.

[0026] In some implementations, the environmental sensing subunit also includes a gas sampling module located at the return air position or top area of ​​the detection hood, used to collect at least one of ozone parameters, volatile organic compound parameters, and cleaning residual gas parameters, and the safety monitoring center writes the gas sampling values ​​into the current environmental parameter record.

[0027] The state sensing subunit is used to collect the vibration, attitude, surface temperature, current axial position, and current circumferential position of the insulating rod. Specifically, the vibration sampling module is installed at the clamping rotating part support to collect the rod's vibration values ​​under clamping conditions; the position sampling module is connected to the angle encoder and displacement encoder to output the current circumferential and axial positions; the attitude sampling module is located near the clamping end to collect the current attitude angle changes of the insulating rod; and the surface temperature sampling module is fixed to the side of the detection head and uses an infrared temperature measurement structure to collect the surface temperature of the measured area. All the above sampling modules are connected to a sampling clock interface with a sampling frequency set to 10Hz, ensuring that environmental sampling values ​​and rod state sampling values ​​are received on the same time reference.

[0028] The synchronous reference calibration unit is positioned at the associated location between the detection field of view and the clamping end, and outputs a reference channel response within the current sampling window. The synchronous reference calibration unit includes a visual reference calibration component, a temperature and humidity coupling reference, and a mechanical stability reference point. The visual reference calibration component is located at the inner edge of the detection field of view and includes a grayscale reference area and a texture reference area. The grayscale reference area reflects changes in current illumination brightness and grayscale, while the texture reference area reflects changes in current image sharpness. Both are present in the field of view during each image acquisition. The temperature and humidity coupling reference is formed by the detection ambient temperature, detection ambient humidity, and the surface temperature of the insulating rod. The safety monitoring center generates the detection ambient dew point temperature based on the detection ambient temperature and humidity, and then generates the dew point margin based on the temperature difference between the insulating rod surface temperature and the detection ambient dew point temperature.

[0029] Mechanical stability reference points are set at the clamping end of the insulating rod, including vibration sampling points and attitude sampling points, to output the mechanical stability reference response under clamping conditions. The reference channel response includes grayscale reference response, texture reference response, temperature and humidity coupling reference response, and mechanical stability reference response. The safety monitoring center uses the reference channel response to determine whether the current image changes, temperature and humidity changes, and mechanical changes have met the stability sampling conditions.

[0030] like Figure 2 As shown, the safety monitoring center divides sampling windows according to a preset sampling period. The reference window is a reference sampling window stored by the safety monitoring center during the system calibration phase. In this embodiment, a sampling window is formed every 100ms. Within the same sampling window, the safety monitoring center simultaneously receives the sampling values ​​from the environmental perception subunit, the sampling values ​​from the state perception subunit, and the reference channel response output by the synchronous reference calibration unit, and assigns a unified sampling window label. The safety monitoring center confirms the current sampling is valid when all three consecutive sampling windows meet the preset validity conditions. In this embodiment, three consecutive sampling windows correspond to a 300ms confirmation time, which can complete a validity confirmation within 1 second, while avoiding the misjudgment of instantaneous fluctuations in a single window as a stable state during clamping back to zero, cover closure, airflow convergence, and illumination stabilization processes.

[0031] The safety monitoring hub comprises a sampling window management module, a reference response analysis module, a monitoring validity parameter generation module, and a validity determination and action output module. The sampling window management module groups environmental sampling values, state sampling values, and reference channel responses at the same time into the same sampling window. The reference response analysis module reads the average brightness of the grayscale reference area, the contrast change between grayscale levels, the sharpness change of the texture reference area, the ambient temperature and humidity, the surface temperature, and the vibration and attitude response of the clamping end. The monitoring validity parameter generation module generates illumination stability based on the brightness and grayscale changes of the visual reference calibration piece within the current sampling window; generates dust obstruction based on dust concentration and the sharpness change of the visual reference calibration piece; generates dew point margin based on the temperature difference between the surface temperature of the insulating rod and the dew point temperature of the detection environment; generates vibration amplitude based on vibration sampling values; and generates attitude drift based on attitude sampling values. The validity determination and action output module determines whether the current sampling meets the validity conditions based on the above monitoring validity parameters and classifies the current sampling as valid, invalid and requiring adjustment, or invalid and requiring resampling.

[0032] In this embodiment, illumination stability is characterized by the average brightness deviation of the grayscale reference area and the contrast change between grayscale levels. Illumination stability is deemed to meet the preset validity conditions when the average brightness deviation of the grayscale reference area relative to the reference window does not exceed 6% and the contrast change between grayscale levels does not exceed 8%. Dust obstruction is characterized by the dust concentration and the decrease in clarity of the texture reference area. Dust obstruction is deemed to meet the preset validity conditions when the dust concentration is not higher than 0.18 mg / m³ and the decrease in edge clarity of the texture reference area does not exceed 12%. Dew point margin is obtained by subtracting the dew point temperature of the detection environment from the surface temperature of the insulating rod. The current measured area is deemed to meet the temperature and humidity stability sampling conditions when the dew point margin is not lower than 3°C. Vibration amplitude is generated from vibration sampling values. The clamping state is deemed to meet the preset validity conditions when the vibration amplitude is not higher than 0.15g. Attitude drift is generated from attitude sampling values. The current detection orientation is deemed to meet the preset validity conditions when the attitude drift is not greater than 0.8°. The above five monitoring validity parameters are used together to characterize whether the current sampling is usable.

[0033] When the light stability, dust obstruction, dew point margin, vibration amplitude, and attitude drift all meet the preset validity conditions, the safety monitoring center classifies the current sample as valid and outputs valid monitoring data and environmental reference fields. Valid monitoring data includes visual monitoring feature data and status monitoring feature data verified by the reference channel response. Visual monitoring feature data includes image edge features, surface texture features, and grayscale distribution features; status monitoring feature data includes current axial position, current circumferential position, attitude value, and surface temperature value. Environmental reference fields include sampling window marker, environmental status marker, current environmental parameter record, and adjustment record fields. In this embodiment, the environmental status marker uses two types of values: stable valid sampling and adjusted valid sampling. The current environmental parameter record includes the detected ambient temperature, relative humidity, illuminance, dust concentration, and surface temperature. When the current sample is invalid, the corresponding invalidation reason and workstation action record are written into the adjustment record field. When the adjusted or resampled sample is confirmed as valid, the safety monitoring center writes the adjustment record field, along with the sampling window marker, environmental status marker, and current environmental parameter record, into the environmental reference field.

[0034] When the illumination stability, dust obstruction, or dew point margin do not meet the preset validity conditions, but the vibration amplitude and attitude drift meet the preset validity conditions, the safety monitoring center classifies the current sampling as invalid and requiring adjustment. When the illumination stability does not meet the preset validity conditions, the safety monitoring center outputs a supplementary lighting command or a shading command. The supplementary lighting and shading components adjust the output power of the ring light source according to the current brightness deviation of the grayscale reference area, or close the lateral shading baffle to suppress local glare. When the dust obstruction does not meet the preset validity conditions, the safety monitoring center outputs a purging command. The purging component sprays clean airflow into the detection field of view and the measured surface through a directional nozzle. After 1.5 seconds, it re-enters the confirmation process of three consecutive sampling windows. When the dew point margin does not meet the preset validity conditions, the safety monitoring center outputs a dehumidification command or a static setting command. The dehumidification component starts internal circulation dehumidification of the enclosure, or the static setting control component maintains the current clamping state and delays for the surface temperature to rise.

[0035] When the vibration amplitude or attitude drift does not meet the preset validity conditions, the safety monitoring center classifies the current sample as invalid and awaiting resampling. If the vibration amplitude does not meet the preset validity conditions, the reset and resampling control component controls the clamping rotating component to maintain clamping and remain stationary for a delay; if the vibration amplitude still does not meet the preset validity conditions after the delay, the clamping rotating component is controlled to return to zero and re-clamp. If the attitude drift does not meet the preset validity conditions, the reset and resampling control component controls the axial movement component to return to the previous stable position and re-triggers the sampling window. When the dew point margin does not meet the preset validity conditions and the vibration amplitude or attitude drift also does not meet the preset validity conditions, the safety monitoring center prioritizes mechanical stability failure as the classification criterion, maintains the current sampling as invalid and awaits resampling, and generates a composite processing command containing dehumidification or static setting commands and reset or resampling commands. The safety monitoring center first controls the reset and resampling control component to perform mechanical recovery actions. After the vibration amplitude and attitude drift meet the preset validity conditions, it then controls the dehumidification component or static setting control component to perform temperature and humidity recovery actions. After the dew point margin, vibration amplitude, and attitude drift have all recovered to the preset validity conditions, it triggers confirmation through three consecutive sampling windows. The workstation adjustment execution unit includes a supplementary lighting and shading component, a purging component, a dehumidification component, a static setting control component, and a reset and resampling control component. The safety monitoring center calls the corresponding component to perform workstation adjustment actions or resampling actions based on the invalidation cause.

[0036] In an actual testing cycle, after the insulating operating rod numbered JG-HJ-0217 entered the testing station, the positioning support completed its support, the clamping rotating component clamped its handheld area and completed zero-position calibration, and the axial moving component moved the testing head to a position 52mm from the front zero point. Within three consecutive sampling windows, the average brightness deviation of the grayscale reference area was 4.2%, the contrast change between grayscale levels was 5.1%, the edge sharpness of the texture reference area decreased by 6.1%, the ambient temperature was 26.3℃, the relative humidity was 66%, the surface temperature sampling module measured the current surface temperature of the insulating rod being tested to be 30.1℃, the safety monitoring center generated the ambient dew point temperature as 19.4℃, the dew point margin as 10.7℃, the vibration amplitude as 0.07g, and the attitude drift as 0.3°. All five monitoring validity parameters met the preset validity conditions. The safety monitoring center classified the current sampling as valid, output the valid monitoring data and environmental reference fields, and marked the environmental state as a stable valid sample.

[0037] When the detection head moves axially to the next detection position, the dust concentration inside the enclosure briefly rises to 0.24 mg / m³, and the edge sharpness of the texture reference area decreases by 17%. Based on the dust sampling value and texture reference response within the same sampling window, the safety monitoring center determines that the dust occlusion does not meet the preset validity conditions, classifies the current sampling as invalid and requiring adjustment, and outputs a purging command. 1.5 seconds after the purging component operates, the dust concentration in the detection area decreases to 0.11 mg / m³, and the texture reference area sharpness recovers to 7%. A confirmation of three consecutive sampling windows is triggered again. During this confirmation process, all monitoring validity parameters again meet the preset validity conditions, the safety monitoring center resumes outputting valid monitoring data, and records the environmental status as a valid sample after adjustment.

[0038] At another detection location, after the insulating rod was transferred from the low-temperature temporary storage area into the detection enclosure, the temperature and humidity sampling module measured the ambient temperature at 24.8℃ and the relative humidity at 78%, while the surface temperature sampling module measured the surface temperature of the insulating rod at 18.1℃. The safety monitoring center generated a detection environment dew point temperature of 20.7℃ and a dew point margin of -2.6℃. Within the same validity confirmation sequence, the vibration sampling module measured a vibration amplitude of 0.19g, and the attitude sampling module measured an attitude drift of 0.9°. Since the dew point margin, vibration amplitude, and attitude drift all failed to meet the preset validity conditions, the safety monitoring center prioritized mechanical stability failure as the classification criterion, maintaining the current sampling as invalid and awaiting resampling. It then generated a composite processing command containing a dehumidification command or a static setting command, as well as a reset command or a resampling command. The safety monitoring center first controlled the reset and resampling control component to perform a mechanical recovery action. After the vibration amplitude and attitude drift met the preset validity conditions, it then controlled the dehumidification component or the static setting control component to perform a temperature and humidity recovery action. After 90 seconds, the relative humidity of the monitored environment dropped to 61%, the surface temperature rose to 22.4℃, the dew point margin recovered to 5.1℃, the vibration amplitude dropped to 0.06g, and the attitude drift dropped to 0.2°. Once the dew point margin, vibration amplitude, and attitude drift all returned to the preset validity conditions, the safety monitoring center triggered three consecutive sampling windows for confirmation. During these three consecutive sampling windows, the current sample again met the preset validity conditions, and the safety monitoring center output valid monitoring data and environmental reference fields.

[0039] To verify the stability of this embodiment under the integrated testing state, 120 sample rods of the same type of insulated operating rod were selected for testing. Each sample rod underwent two rounds of independent testing, and after the two rounds of testing, it was renumbered and randomly rearranged, for a total of 240 tests. The test environment temperature was controlled between 24℃ and 27℃, the relative humidity was controlled between 55% and 78%, and the sampling frequency was maintained at 10Hz. Statistical results showed that in 231 out of 240 tests, valid monitoring data was directly output in the first three consecutive sampling windows. Validity was restored in 6 cases after purging, and in 3 cases after dehumidification, settling, and resetting. The first confirmation validity rate was 96.3%, and the validity recovery rate after station adjustment was 100%. In all test records, the environmental reference fields were consistent with the corresponding sampling window, corresponding environmental parameters, and corresponding adjustment records 240 times. The above test process shows that this embodiment can first identify environmental disturbances and mechanical disturbances within the automatic detection cycle, and then restore the sampling conditions through the workstation adjustment execution unit, so that the output effective monitoring data has a clear sampling window source and environmental state source, and the invalid reasons and workstation action records can be traced by the safety monitoring center.

[0040] Example 2 This embodiment is applied to the return inspection station in a smart tool warehouse. This return inspection station uses the same insulated rod inspection station, safety monitoring center, and station adjustment execution unit as in Embodiment 1, and also adopts the full-dimensional environmental perception network, synchronous reference calibration unit, sampling window division method, and monitoring effectiveness judgment logic from Embodiment 1. Compared to Embodiment 1, the insulated rod in this embodiment undergoes warehouse transfer and temperature difference conversion before entering the inspection area. The station is more prone to simultaneous condensation risks, external reflections, and mechanical residual disturbances, making it more suitable for verifying the sampling effectiveness recovery process under combined interference conditions.

[0041] After the insulating rod is sent into the detection area by the return slide, the positioning support completes the support, the clamping rotating part clamps the tail end sealing area and keeps it fixed, the detection cover closes, the safety monitoring center divides the sampling window according to the 100ms sampling period, and takes 3 consecutive sampling windows as a validity confirmation sequence.

[0042] During the initial validity confirmation process after the insulating rod moves from the 12℃ temporary storage area to the 25℃ detection area, the temperature and humidity sampling module measured the ambient temperature at 25.1℃ and the relative humidity at 76%, while the surface temperature sampling module measured the surface temperature of the insulating rod at 16.5℃. The safety monitoring center generated a dew point temperature of 20.6℃ for the detection environment, resulting in a dew point margin of -4.1℃. Simultaneously, the vibration sampling module measured a vibration amplitude of 0.21g, and the attitude sampling module measured an attitude drift of 1.1°. Since the dew point margin, vibration amplitude, and attitude drift all fail to meet the preset validity conditions, the safety monitoring center prioritizes mechanical stability failure, classifying the current sampling as invalid and requiring resampling. It then generates a composite processing command containing either a dehumidification command or a static setting command, as well as a reset command or a resampling command. The safety monitoring center first controls the reset and resampling control component to perform a mechanical recovery action. Only after the vibration amplitude and attitude drift meet the preset validity conditions is the dehumidification component or the static setting control component controlled to perform a temperature and humidity recovery action. After a 90-second recovery period, three consecutive sampling windows were triggered for confirmation. At this time, the relative humidity of the monitored environment dropped to 62%, the surface temperature rose to 22.0℃, the dew point margin recovered to 4.8℃, the vibration amplitude dropped to 0.06g, and the attitude drift dropped to 0.2°. All of the above monitoring validity parameters were restored to the preset validity conditions. The safety monitoring center classified the current sampling as valid and output the valid monitoring data and environmental reference fields. The environmental status was marked as a valid sample after adjustment.

[0043] At another detection location, localized glare occurred in the detection field of view due to reflections from adjacent cabinet doors. Within three consecutive sampling windows, the average brightness deviation of the grayscale reference area increased to 9%, and the contrast change between grayscale levels increased to 10%, while dust obscuration, dew point margin, vibration amplitude, and attitude drift all met the preset validity conditions. Based on this, the safety monitoring center determined that the illumination stability did not meet the preset validity conditions, classified the current sampling as invalid and requiring adjustment, and issued a shading command. After the supplementary lighting shading component closed the shading baffle, it triggered another three consecutive sampling windows for confirmation. In these three consecutive sampling windows, the average brightness deviation of the grayscale reference area recovered to 4%, and the contrast change between grayscale levels recovered to 6%, meaning the current sampling once again met the preset validity conditions. The safety monitoring center resumed outputting valid monitoring data and marked the environmental status as a valid sample after adjustment.

[0044] This embodiment demonstrates that in the scenario of returning to the warehouse for inspection, even if condensation risk, mechanical disturbance, and local reflection occur successively, the safety monitoring center can still use the environmental sampling value, status sampling value, and reference channel response within the same sampling window as a common basis to determine the validity of the current sampling, and call the corresponding workstation adjustment action or re-sampling action according to the reason for invalidity, thereby ensuring the validity and traceability of the final output data.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.

[0046] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The environmental sensing subunit is used to collect the temperature, humidity, light intensity, and dust concentration of the detection environment, while the state sensing subunit is used to collect the vibration, attitude, surface temperature, current axial position, and current circumferential position of the insulating rod. The synchronous reference calibration unit is used to output a reference channel response within the current sampling window. The safety monitoring center divides the sampling window according to a preset sampling period and receives the sampling values ​​from the environmental sensing subunit, the state sensing subunit, and the reference channel response output by the synchronous reference calibration unit within the same sampling window. It generates monitoring validity parameters including light stability, dust obstruction, dew point margin, vibration amplitude, and attitude drift, and determines whether the current sampling meets the validity conditions based on the monitoring validity parameters. When the current sampling meets the validity conditions, it outputs valid monitoring data and environmental reference fields. When the current sampling does not meet the validity conditions, it outputs a station adjustment command or a re-sampling command based on the reason for invalidity.
