Description

Technical Field

[0001] The present invention relates to the technical field of power systems, and in particular to a low-voltage branch box fault early warning method, system, device and storage medium. Background Art

[0002] The low-voltage branch box is a device used in low-voltage power distribution systems. With the rapid development of power systems, low-voltage branch boxes have become an important part of power systems, and their safety and stability are crucial to the operation of the entire power system.

[0003] Low-voltage branch boxes are usually installed outdoors. Due to the complex outdoor environmental factors, the electrical components in the low-voltage branch box may have problems due to various environmental factors, such as loose and falling plugs, damaged lines, and water leaks. In the prior art, since low-voltage branch boxes are distributed in various places outdoors, in order to ensure that the low-voltage branch boxes can be used normally, staff usually need to go to the site regularly for field inspections. However, when a safety problem occurs with the low-voltage branch box, the staff cannot understand the situation of the low-voltage branch box in real time, nor can they solve the problem immediately. By the time the staff discovers the problem, the safety problem of the low-voltage branch box may have been magnified, so the safety is low. Summary of the invention

[0004] In order to improve the safety of a low-voltage branch box and enable a low-voltage branch box to provide a fault warning, the present invention provides a low-voltage branch box fault warning method, system, device and storage medium.

[0005] In a first aspect, the present invention provides a low-voltage branch box fault early warning method, which adopts the following technical solution:

[0015] By adopting the above technical solution, the low-voltage branch box can take photos and monitor the inside in real time. When the monitoring finds that there are safety problems with the socket characteristics and plug characteristics, the low-voltage branch box can promptly feedback to the terminal and issue an alarm to notify the staff to handle it in time. The low-voltage branch box can also classify and identify the safety problems that arise, and can adopt different temporary pre-processing methods for safety problems in different situations, so that the safety problems are not easy to expand further before the arrival of the staff. Compared with the existing technology, the low-voltage branch box in the above solution has higher safety.

[0035] By adopting the above technical solution, when the camera detects that there is an obstruction blocking the plug and the socket, the camera can actively monitor and search for the gap position. When the gap position cannot be found, the system can drive the hook to lift the obstruction, so that the camera can always obtain the connection status of the plug and the socket, thereby improving safety.

[0036] Optionally, also include:

[0037] Determine whether the image information inside the box is consistent with the preset occlusion image;

[0038] If and only if the image information inside the box is consistent with the occluded image, it is defined as display abnormality, and the foreign body pressure value on the shooting device is obtained;

[0039] Determine whether the foreign body pressure value exceeds the preset damage pressure value;

[0040] If and only if the foreign body pressure value does not exceed the damage pressure value, control the camera to move according to the preset displacement distance, obtain the foreign body pressure value again, and determine whether the foreign body pressure values ​​obtained twice are consistent;

[0041] If the foreign body pressure values ​​obtained twice are inconsistent, the camera is controlled to move according to the preset maximum displacement distance to determine whether the foreign body pressure value is 0;

[0042] If the foreign body pressure value is 0, the shooting device is controlled to work;

[0043] If the foreign body pressure value is not 0, the camera will be reset, feedback information will be output and an alarm will be issued;

[0044] If the foreign body pressure values ​​obtained twice are consistent, the camera is controlled to shake according to a preset vibration amplitude value, and whether the foreign body pressure values ​​obtained twice are consistent is further determined;

[0045] If and only if the foreign body pressure value is consistent, continue to determine whether the foreign body pressure value is 0;

[0046] If it is not 0, the obstruction is defined as a wet foreign object, the preset blowing device is controlled to dry and separate the obstruction, and the shooting device is controlled to work;

[0047] If it is 0, the obstruction is defined as dust, and the moving path of the camera and the preset erasing position is analyzed based on the image information inside the box;

[0048] The shooting device is controlled to move to the erasing position according to the moving path to erase the dust, and the shooting device is controlled to work.

[0049] By adopting the above technical solution, when there are heavy objects attached to the camera, the system can control the camera to move, vibrate, and automatically find a path for cleaning according to the different attached objects, so that the camera image can always monitor the low-voltage branch box to ensure the safety inside the low-voltage branch box.

[0050] Optionally, also include:

[0051] Obtain global image information inside the low voltage branch box;

[0052] Based on the global image information, the image is matched with the preset aging image library to obtain the aging features and the aging feature positions;

[0053] Get the crack area value of the aging feature;

[0054] The total amount of glue dripping is obtained based on the crack area value matching;

[0055] Obtain the wire harness feature position and the number of wire harness features based on the global image information and the wire harness feature matching around the aging feature position;

[0056] Determine whether the number of harness features is 0;

[0057] When and only when the value of the wire harness feature quantity is not 0, obtain the impact distance value between the aging feature position and the wire harness feature position, and obtain the isolation position according to the impact distance value matching; according to the isolation position, control the preset insulating paper to isolate the aging feature position from the wire harness feature position, and according to the total amount of glue dripping, control the preset glue dripping equipment to drip the insulating glue on the aging feature position, output feedback information and issue an alarm.

[0058] By adopting the above technical solution, the low-voltage branch box identifies the aging and damage problems of the wiring harness and considers the impact on the characteristics of other components during the processing of the aging and damage problems, so that the normal use of other electrical components is not affected when the aging and damage problems are processed.

[0059] Optionally, also include:

[0060] Get the internal humidity value in the low voltage branch box;

[0061] Determine whether the internal humidity value is greater than a preset reference humidity value;

[0062] If and only if the internal humidity value is greater than the reference humidity value, obtain the high humidity area range;

[0063] Obtain humidity image information within high humidity areas;

[0064] Determine the location of water leakage based on humidity image information;

[0065] According to the water leakage position, the preset plugging device is controlled to seal with the preset waterproof glue, the preset drying device is controlled to dry, feedback information is output and an alarm is issued, and it is judged again whether the internal humidity value is greater than the preset reference humidity value;

[0066] If and only if the internal humidity value is greater than the preset reference humidity value, it is defined as an external water ingress fault, and feedback information is output and an alarm is given.

[0067] By adopting the above technical solution, the system can accurately obtain the damaged location of the low-voltage branch box according to the humidity conditions inside the low-voltage branch box, based on sensors and infrared probes, and seal the damaged part with plasticine in time, so that the low-voltage branch box can remain dry and can continue to be used before the staff repairs it, which is safer.

[0068] Optional solutions for external water ingress failure include:

[0069] Get the external humidity value of the low voltage branch box;

[0070] Determine whether the external humidity value is greater than the reference ambient humidity value;

[0071] If the external humidity value is not greater than the reference ambient humidity value, the moisture frequency value of the low-voltage branch box of a preset time length is obtained;

[0072] Determine whether the damp frequency value is greater than a preset reference frequency value;

[0073] When and only when the damp frequency value is greater than the preset reference frequency value, the preset baffle device is controlled to block and protect the low-voltage branch box, and the preset alarm device is controlled to sound an alarm;

[0074] If the external humidity value is greater than the reference environmental humidity value, the inner cavity water level value is obtained;

[0075] Determine whether the water level value in the inner cavity is greater than the preset warning water level value;

[0076] When and only when the water level value in the inner cavity is greater than the warning water level value, the preset drain valve is controlled to drain water and the water level growth rate is obtained;

[0077] If the water level growth rate is greater than 0, the peak time is calculated based on the inner cavity water level value, the preset red line water level value and the water level growth rate;

[0078] Determine whether the peak time is greater than the preset estimated arrival time;

[0079] If it is greater, the peak time will be output to the terminal and an alarm will be issued;

[0080] If it is not greater than, the preset cutting device is controlled to cut off the power supply to the low-voltage branch box, and the peak time is output to the terminal and an alarm is sounded.

[0102] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0103] The embodiment of the present application discloses a low-voltage branch box fault early warning method.

[0104] Reference Figure 1 , a low-voltage branch box fault early warning method, comprising the following steps:

[0105] S100: Acquiring internal image information of a low-voltage branch box at a preset installation position;

[0106] The installation position refers to the location of the socket features and plug features in the low-voltage branch box. The socket features and plug features in each model of low-voltage branch box are installed in a fixed position, so the positions of the socket features and plug features are determined.

[0107] The box internal image information refers to the image inside the low-voltage branch box obtained by a camera arranged inside the low-voltage branch box. The box internal image information here includes the socket features and the plug features.

[0108] S101: Analyzing and obtaining a socket position and a plug position based on the internal image information of the cabinet and preset socket features and plug features;

[0109] Since the installation positions of the socket features and the plug features are determined, and the proportion of the image information inside the box is also determined, according to the positions of the socket features and the plug features in the image information inside the box and the installation positions, the position of the camera is taken as the zero point position, and the socket position and the plug position of the socket features and the plug features relative to the zero point position can be determined. The socket position and the plug position are the coordinate point positions of the socket features and the plug features.

[0110] S102: Calculate the distance between the socket position and the plug position and define it as a clearance value.

[0111] The pull-out clearance value refers to the distance between the plug feature and the socket feature after assembly. Based on the socket position and the plug position and using the distance formula between the two points, the pull-out clearance value can be calculated.

[0112] The direct consequence of the increase in the pull-out gap value is that the plug feature falls out of the socket feature, thereby causing the low-voltage branch box to lose power.

[0113] S103: Determine whether the escape gap value is greater than the reference gap value;

[0114] The reference gap value is the distance between the plug feature and the socket feature when the two are firmly assembled. The reference gap value is a reference value set by the technician, and this parameter is usually 0.

[0115] By comparing the two sizes, it can be determined whether the plug feature has been dislodged from the socket feature.

[0116] S104: if and only if the escape gap value is greater than the reference gap value, identifying the jack outline on the socket feature based on the internal image information of the box;

[0117] The jack outline refers to the outline of the jack in the plug feature, and the jack outline can be identified through the image information inside the box. In order to prevent the camera from being blocked by the plug feature when acquiring the jack outline, two cameras are set in the low-voltage branch box, and the cameras are located on both sides.

[0118] S105: Determine whether the jack outline exceeds the range of the reference jack outline;

[0119] The reference jack profile refers to the standard outline size of the jack in the socket characteristics. The reference jack profile is a national standard value and is not described here. The reference jack profile is a standard used to measure whether the jack is enlarged.

[0120] If the jack profile does not exceed the range of the reference jack profile, the jack is good.

[0121] If the jack outline exceeds the reference jack outline, the jack has been enlarged. As a result of the jack enlargement, the plug features have been pulled out of the receptacle features.

[0122] S106: When and only when the jack profile exceeds the range of the reference jack profile, control the preset pushing device to insert the plug feature into the socket feature, and control the preset fixing sleeve to fix the plug feature to the socket feature;

[0123] The pushing device can push the plug feature back into the socket feature by abutting against the plug feature. The fixing sleeve can cover the plug feature on the socket feature so that the plug feature is not easy to come out again within a period of time.

[0124] When it is confirmed that the reason for the plug feature to be disengaged from the socket feature is the expansion of the socket, the plug feature is pushed back into the socket feature by the pushing device, and the plug feature is temporarily fixed by the fixing sleeve.

[0125] S107: Determine environmental factor information based on the image information inside the box, output the environmental factor information as feedback and issue an alarm.

[0126] Environmental factor information refers to the environmental reasons that cause the expansion of the jack. The environmental factor information can be clarified by analyzing and identifying the image information inside the box.

[0127] After obtaining the environmental factor information, it can be fed back to the background terminal and an alarm can be issued to notify the staff to carry out maintenance in time.

[0128] Reference Figure 2 The environmental factor information includes a heavy object pressing on the plug feature, thereby expanding the jack. In this embodiment, the heavy object pressing on the plug feature is mainly a wire harness. The environmental factor information analysis and processing method includes the following steps:

[0129] S200: Acquire image information of a heavy object above the plug position;

[0130] The heavy object image information refers to the image above the plug position obtained by the camera. The reason for the expansion of the socket may be that a heavy object is pressed on the plug feature, so the top of the plug feature is photographed first.

[0131] S201: Matching the heavy object image information with a preset image recognition library to obtain an extrusion feature, where the extrusion feature includes a wire harness feature.

[0132] The image recognition library is a database obtained by deep learning based on a neural network model, which includes the feature models of all objects that may exist in the low-voltage branch box. The image recognition library is a reference database set by technicians and will not be described in detail here.

[0133] The squeeze feature refers to the weight pressing on the plug feature.

[0134] By matching the heavy object image information with the image recognition library, if an extrusion feature exists, the extrusion feature can be matched and obtained.

[0135] S202: Determine the extrusion position points of the plug features and the harness features based on the internal image information of the box.

[0136] The extrusion location point is the abutment point between the wire harness feature and the plug feature. The wire harness feature presses on the plug feature at this location, causing problems between the plug feature and the socket feature.

[0137] When the plug features and the harness features in the image information inside the box are identified and confirmed, the extrusion position point between the two can be confirmed from the image information inside the box.

[0138] S203: Determine the bundling position points on both sides of the extrusion position point in the wire harness feature based on the extrusion position point and a preset reference bundling distance.

[0139] The bundling position point is a position on both sides of the extrusion position point on the harness feature. This position is located on the harness feature and does not abut the plug feature. The bundling position point is used for bundling with cable ties and is lifted by the cable ties. After the harness feature is lifted, the extrusion position point will not sag so that the plug feature can be separated from the harness feature.

[0140] S204: Determine a lift distance value based on a preset installation gap value between adjacent plug features.

[0141] Multiple rows of plug features are installed in the low-voltage branch box along the height direction. The installation gap value is the gap value between adjacent plug features in the vertical direction. The installation gap value is the standard value in the low-voltage branch box and will not be elaborated here.

[0142] The lift distance value refers to the height value of the harness feature raised by the cable tie. The lift distance value needs to be smaller than the installation clearance value, and after the harness feature is lifted according to the lift distance value, the harness feature can be separated from the plug feature. Therefore, the lift distance value needs to be associated with the installation clearance value, and the lift distance value can be analyzed through the installation clearance value.

[0143] S205: Controlling a preset bundling device to bundle the wire harness features with a preset tie band according to the bundling position point, and controlling a preset lifting device to lift and fix the wire harness according to the lifting distance value.

[0144] After determining the two parameters of the bundling position point and the lifting distance value, the harness features can be bundled at the bundling position point by using a cable tie, and then the cable tie and the harness features can be simultaneously lifted and fixed by a lifting device, thereby separating the harness features from the plug features.

[0145] Reference Figure 3 , the processing method when the plug feature is blocked by foreign objects and the camera cannot obtain the plug feature includes the following steps:

[0146] S300: Obtaining a covering state type of the plug feature based on a comparison analysis of the internal image information of the box and the plug feature, where the covering state type includes a covering type and an uncovering type;

[0147] The covering state type refers to whether the plug feature in the internal image information of the box obtained by the camera is covered by an obstruction. If there is an obstruction between the plug feature and the camera, the plug feature may be blocked by the obstruction.

[0148] By comparing and analyzing the internal image information of the box and the plug features to determine whether the two are consistent, it is possible to determine whether the plug features are covered by obstructions.

[0149] If the plug features are covered by an obstruction, the camera cannot normally obtain the information of the plug features and the socket features. There are safety hazards in the plug features and the socket features, which need to be dealt with in a timely manner. If the plug features are not covered by an obstruction, the camera can clearly obtain the information of the plug features.

[0150] S301: Based on the covering type, obtain the falling distance value of the covering object, and obtain the covering range according to the falling distance value.

[0151] The drop distance value is the distance between the obstruction and the camera. The obstruction range refers to the limited range area where the obstruction can block the camera so that the camera cannot normally obtain the plug features and the socket features.

[0152] When there is an obstruction between the plug feature and the shooting device, the shooting device can analyze the distance between the obstruction and the shooting device by taking a picture of the obstruction, and calculate the obstruction range by analyzing the obstruction distance and the installation position.

[0153] S302: Obtaining a preset moving distance value of the shooting device based on the occlusion range analysis.

[0154] The moving distance value refers to the moving distance that the shooting device can move out of the blocking range by moving the shooting device.

[0155] S303: Control a preset shooting device to move according to the moving distance value, and obtain a gap position between the plug feature and the obstruction.

[0156] The gap position refers to the gap between the plug feature and the obstruction that enables the shooting device to obtain the plug feature and the socket feature.

[0157] By moving the camera, when the camera can capture the plug feature and the socket feature again, it means that the position is a gap position. The plug feature and the socket feature captured at the gap position are not necessarily complete features.

[0158] S304: Control the photographing device to reacquire the image information of the interior of the box at the installation position at the gap position, and determine the covering state type of the plug feature.

[0159] In order to confirm that the shooting device can obtain complete plug features and socket features in the gap position, it is necessary to determine again whether the obtained plug features are covered by obstructions.

[0160] S305: If it is a covering type, obtain the weight value of the covering object.

[0161] If the plug feature is not covered at this time, it means that the camera can obtain both features at the gap position, and no other processing is required. If the plug feature is still covered by an obstruction at this time, the complete image of the plug feature cannot be obtained by moving the camera, and the obstruction needs to be processed.

[0162] The weight value is the weight value of the occluder, and the processing method of the occluder is determined by the weight value. The weight value of the occluder is obtained by obtaining the volume of the occluder and identifying the material of the occluder and matching it with the preset material database.

[0163] S306: Determine whether the weight value is greater than the reference weight value.

[0164] The reference weight value is a standard for determining whether the obstruction can be processed. It is a reference value set by the technicians and will not be described in detail here.

[0165] S3061: If the weight value is greater than the reference weight value, feedback information is output and an alarm is issued.

[0166] If the weight value is greater than the reference weight value, it means that the mass of the obstruction is too heavy and the obstruction cannot be handled by the hook. Feedback and alarm are required to the background terminal.

[0167] S3062: If the weight value is not greater than the reference weight value, determine the hook position of the obstruction and the thickness of the obstruction at the hook position according to the image information inside the box.

[0168] If the weight value is not greater than the reference weight value, it indicates that the obstruction is relatively light, and the harness feature can be lifted by the hook device.

[0169] The hook position refers to the position where the hook can be fixed on the occluder, and the hook position can be obtained by matching and analyzing the feature image information. The occluder thickness is the thickness of the occluder in the height direction at the hook position.

[0170] S30621: Obtain a lifting distance between the hook position and a preset hook device, and determine a pull-down distance based on the lifting distance and the thickness of the obstruction.

[0171] The hook device is provided with a hook, and the hook is wound on the hook device through a rope. The hook device can lower the hook and hook it on the hook position of the shielding object by rotating.

[0172] The pull-down distance is the distance that the hook device lowers the hook to hook the shield. The lifting distance is the distance that the hook device pulls the shield upward after the hook hooks the shield. The pull-down distance should be greater than the lifting distance, and the pull-down distance is the sum of the lifting distance and the thickness of the shield.

[0173] S30622: Control the hook device according to the pull-down distance to suspend the preset hook to the hook position of the obstruction and hook the obstruction, and control the hook device according to the lifting distance to lift the obstruction.

[0174] When the hook drops to the hook position and lifts the obstruction upward, the weight of the obstruction needs to be detected. If the weight of the obstruction is 0, it means that the hook has not hooked the obstruction. At this time, the hook needs to be shaken so that the hook hooks the obstruction during the shaking process.

[0175] Reference Figure 4 , the processing method when the obstruction is attached to the shooting device includes the following steps:

[0176] S400: Determine whether the image information inside the box is consistent with the preset blocking image.

[0177] The occlusion image refers to the image captured by the camera when the camera is blocked by an occlusion object.

[0178] By comparing the internal image information of the box and the occlusion image, it can be determined whether the camera is blocked.

[0179] S401: If and only if the image information inside the box is consistent with the blocked image, it is defined as display abnormality, and the foreign matter pressure value on the shooting device is obtained;

[0180] If the internal image information is consistent with the occlusion image, it means that the camera is blocked by the occlusion object and the camera cannot obtain the image normally.

[0181] The foreign body pressure value refers to the pressure value of the obstruction attached to the shooting device on the shooting device.

[0182] S402: Determine whether the foreign body pressure value exceeds a preset damage pressure value.

[0183] The damage pressure value is a reference value for judging whether the obstruction can be removed. The damage pressure value is an artificially set reference value and will not be elaborated here.

[0184] S403: If and only if the foreign body pressure value does not exceed the damage pressure value, control the camera to move according to a preset displacement distance, obtain the foreign body pressure value again, and determine whether the foreign body pressure values ​​obtained twice are consistent;

[0185] If the foreign body pressure value is greater than the damage pressure value, it means that the obstruction attached to the camera is too heavy to be removed. At this time, feedback information can be sent to the background and an alarm can be issued.

[0186] If the obstruction is just against the camera, the obstruction can be moved away from the camera by moving the camera. The displacement distance refers to the distance the camera moves when separating the camera from the obstruction. The displacement distance is a reference value set by the technician and will not be described in detail here.

[0187] If the foreign object pressure value is not greater than the damage pressure value, the camera is moved and the foreign object pressure value is reacquired. Whether the foreign object pressure value changes is determined to determine whether the method of moving the camera is effective in removing the obstruction.

[0188] S4031: If the foreign body pressure values ​​obtained twice are inconsistent, control the camera to move according to a preset maximum displacement distance to determine whether the foreign body pressure value is 0;

[0189] If the foreign body pressure values ​​obtained twice are inconsistent, it means that the method of moving the camera is effective. The maximum displacement distance refers to the maximum distance that the camera can move in the low-voltage branch box. Control the maximum displacement distance of the camera movement, and then determine whether the obstruction has been removed through the foreign body pressure value.

[0190] S40311: If the foreign body pressure value is 0, control the shooting device to work.

[0191] When the foreign object pressure value obtained after the camera moves the maximum displacement distance is 0, it means that the obstruction has been removed from the camera. At this time, the camera can be controlled to obtain images normally.

[0192] S40312: If the foreign body pressure value is not 0, reset the camera, output feedback information and issue an alarm.

[0193] When the foreign object pressure value obtained after the camera moves the maximum displacement distance is not 0, it means that although the mobile camera is effective in removing obstructions, it is limited by the space size of the low-voltage branch box and is not enough to remove the obstruction. At this time, the shooting device is reset, feedback information is output and an alarm is issued.

[0194] S4032: If the foreign object pressure values ​​obtained twice are consistent, the camera is controlled to shake according to a preset vibration amplitude value, and it is further determined whether the foreign object pressure values ​​obtained twice are consistent;

[0195] If the foreign body pressure values ​​obtained twice are consistent, it means that the method of moving the camera is ineffective. In this case, other methods need to be used to remove the obstruction.

[0196] The vibration amplitude value refers to the vibration amplitude when the camera can shake off the obstruction through vibration. The vibration amplitude value is a reference value set by the technician and is not described here. If the foreign object pressure values ​​reacquired after the camera is vibrated are consistent, it means that the vibration has no effect and the obstruction may be stuck to the camera lens. If the foreign object pressure values ​​reacquired after the camera is vibrated are inconsistent, it means that vibrating the camera is effective in removing the obstruction. At this time, continue to vibrate the camera until the obstruction is removed.

[0197] S40321: If and only if the foreign body pressure values ​​are consistent, continue to determine whether the foreign body pressure value is 0;

[0198] The foreign body pressure value of 0 is used as a standard to distinguish whether the obstruction is dust, because the mass of dust is negligible and dust has no pressure on the shooting equipment.

[0199] S403211: If the foreign object pressure value is not 0, the obstruction is defined as a wet foreign object, the preset blowing device is controlled to dry and separate the obstruction, and the shooting device is controlled to work.

[0200] As for the wet foreign matter, it is light in weight and can be handled by the blowing device. First, it is blown dry by the blowing device, and then it is blown away by the blowing device after the covering is dry.

[0201] S403212: If the foreign object pressure value is 0, the obstruction is defined as dust, and the moving path of the shooting device and the preset erasing position is analyzed based on the image information inside the box;

[0202] For dust, an erasing device is provided in the low-voltage branch box to wipe off the dust on the lens of the shooting equipment. The erasing device is mainly in the form of a rag. The erasing device is fixedly installed at a fixed position in the low-voltage branch box. The erasing position is the position where the erasing device is located. This position is a known position and can be directly obtained from the image information inside the box.

[0203] The moving path is the path that the camera moves from its location to the erasing location. The moving path can analyze and obtain the image information inside the box according to the camera location and the erasing location. In the process of obtaining the moving path, the system can analyze the blocking features on the moving path through the image information inside the box, and the moving path can bypass the blocking features.

[0204] S4032121: Control the shooting device to move to the erasing position to erase dust according to the moving path, and control the shooting device to work.

[0205] After the moving path is determined, the photographing device can move along the moving path to the erasing position to erase the dust through the erasing device.

[0206] Reference Figure 5 , the low-voltage branch box fault type also includes aging and damage. The fault warning method for aging and damage includes the following steps:

[0207] S500: Acquire global image information in the low-voltage branch box.

[0208] The global image information refers to the image inside the low-voltage branch box obtained by the camera.

[0209] S501: Matching the global image information with a preset aging image library to obtain aging features and acquire the aging feature positions.

[0210] The aging image library is a database obtained based on deep learning of neural networks, and includes images of various forms of aging and damage of wiring harnesses. The aging image library is a database set by technicians and will not be described in detail here.

[0211] The aging feature refers to the aging and damage on the wire harness. The aging feature location refers to the aging and damage location on the wire harness.

[0212] S502: Obtain the crack area value of the aging feature.

[0213] The crack area value refers to the size of the aging and damaged area on the wire harness, and the crack area value can be analyzed and obtained from the image information inside the box.

[0214] S503: Obtain the total amount of glue dripping based on the crack area value matching.

[0215] When the wiring harness is aged and damaged, temporary remedy can be achieved by dripping insulating glue to the damaged position. The total amount of glue dripping is the amount of insulating glue required to be used calculated based on the crack area value. The total amount of glue dripping corresponds to the crack area value one by one and can be directly matched by the crack area value.

[0216] S504: Obtaining the wire harness feature position and the number of wire harness features based on the global image information and the wire harness feature matching around the aging feature position.

[0217] According to the position of the wire harness feature in the global image information, the position of the aging feature is taken as the zero point position, and the position of the wire harness feature relative to the aging feature position can be determined. And the number of wire harness features can be matched from the global image information.

[0218] When dripping insulating glue on the aging features of the wiring harness, if there are other wiring harness features around the aging feature position, the insulating glue may stick the two wiring harness features together when dripping on the other wiring harness features. Therefore, it is necessary to identify whether there are other wiring harness features around the aging feature position and isolate them.

[0219] S505: Determine whether the harness feature quantity value is 0.

[0220] If the value of the number of harness features is 0, it means that there are no other harness features around the aging feature. In this case, the insulating glue can be dripped directly on the aging feature.

[0221] S506: When and only when the wire bundle feature quantity value is not 0, obtain the influence distance value between the aging feature position and the wire bundle feature position, and obtain the isolation position according to the matching of the influence distance values.

[0222] The influence distance value refers to the distance between the aging feature location and the harness feature.

[0223] The isolation position refers to the position used to place the isolation device. The isolation position is located between the aging feature position and the harness feature, so the isolation position is determined by the impact distance value.

[0224] S507: according to the isolation position, the preset insulating paper is controlled to isolate the aging characteristic position from the wiring harness characteristic position, and according to the total amount of glue dripping, the preset glue dripping equipment is controlled to drip the insulating glue on the aging characteristic position, and feedback information is output and an alarm is issued.

[0225] In this embodiment, the isolation device is insulating paper. When an aging feature is identified, insulating glue is dripped on the aging feature by glue dripping equipment, and before dripping glue, it is first identified whether there are other wiring harness features around the aging feature position. If there are, insulating paper is inserted between the aging feature and the wiring harness feature to isolate them.

[0226] Reference Figure 6 The fault type of low-voltage branch box also includes faults caused by moisture and water ingress. The fault warning method for moisture and water ingress includes the following steps:

[0227] S600: Obtain the internal humidity value in the low-voltage branch box.

[0228] The internal humidity value refers to the ambient humidity inside the low-voltage branch box.

[0229] S601: Determine whether the internal humidity value is greater than a preset reference humidity value.

[0230] The reference humidity value is a reference standard for measuring whether water has entered the low-voltage branch box. The reference humidity value is a reference value set by the technicians and will not be elaborated here.

[0231] S602: When and only when the internal humidity value is greater than the reference humidity value, obtain the high humidity area range.

[0232] When the internal humidity value is not greater than the reference humidity value, it means that the inside of the low-voltage branch box is dry and the system does not need to issue a fault warning.

[0233] The high humidity area refers to the area where the humidity on the surface of the low-voltage branch box is high. There are many humidity sensors in the low-voltage branch box, and the high humidity area can be analyzed by the humidity sensors.

[0234] When the internal humidity value is greater than the reference humidity value, it indicates that water may have entered the low-voltage branch box. At this time, the high humidity area range is obtained through the humidity sensor.

[0235] S603: Acquire humidity image information within the high humidity area.

[0236] Humidity image information refers to the image information of the inner surface of the low-voltage branch box obtained by the infrared probe. Since the inner surface of the low-voltage branch box is painted with humidity-sensitive paint, the color of the image presented is different according to the humidity level. The image color area at the leak is the smallest, with the leak as the center. The farther away from the leak, the lower the humidity, and the image color also changes in a step-like manner from the leak as the center.

[0237] S604: Determine the water leakage location based on the humidity image information.

[0238] The leaking position refers to the position where the water leaks on the inner surface of the low-voltage branch box. By analyzing the color in the humidity image information, the place with the smallest image color area is the leaking position.

[0239] S605: According to the water leakage position, the preset sealing device is controlled to seal with the preset waterproof glue, the preset drying device is controlled to dry, feedback information is output and an alarm is issued, and it is determined again whether the internal humidity value is greater than the preset reference humidity value.

[0240] In case of water leakage on the inner surface of the low-voltage branch box, in order to prevent the low-voltage branch box from leaking further, first use the sealing device to block the waterproof glue at the leaking position, and then use the drying device to dry it when water does not continue to enter the low-voltage branch box. The above methods are only temporary solutions. After the system makes the above solutions, it will send feedback information to the background terminal and issue an alarm.

[0241] After adopting the above solution, it is necessary to determine the internal humidity value again to determine whether the low-voltage branch box is leaking only due to damage.

[0242] S606: If and only if the internal humidity value is greater than the preset reference humidity value, it is defined as an external water inflow fault, and feedback information is output and an alarm is issued.

[0243] After being treated with waterproof glue, the internal humidity value in the low-voltage branch box is still greater than the reference humidity value, indicating that the reason for moisture and water ingress in the low-voltage branch box is not due to surface damage, but an external water ingress failure.

[0244] Reference Figure 7The method for handling external water inflow failure includes the following steps:

[0245] S700: Get the external humidity value of the low-voltage branch box.

[0246] The external humidity value refers to the ambient humidity outside the low-voltage branch box.

[0247] S701: Determine whether the external humidity value is greater than the reference ambient humidity value.

[0248] S7011: If the external humidity value is not greater than the reference ambient humidity value, obtain the moisture frequency value of the low-voltage branch box for a preset time length.

[0249] The benchmark ambient humidity value is a reference value for measuring whether there is continuous precipitation. It is a reference value set by technical personnel and will not be elaborated here.

[0250] If the external humidity value is not greater than the reference ambient humidity value, it means that it is not raining outside the low-voltage branch box, and the reason for water entering the low-voltage branch box may be that someone accidentally splashed water on the low-voltage branch box or children played and got water into the low-voltage branch box.

[0251] The moisture frequency value refers to the frequency at which the system detects that the external humidity value of the low-voltage branch box increases within a period of time.

[0252] S70111: Determine whether the damp frequency value is greater than a preset reference frequency value.

[0253] The reference frequency value is used to measure whether the cause of moisture and water ingress on the outside of the low-voltage branch box is intentional or unintentional. The reference frequency value is a reference value set by technical personnel and will not be elaborated here.

[0254] If the dampness frequency value is greater than the reference frequency value, it may be due to unintentional human factors, such as regular watering, watering, flushing, and road washing.

[0255] If the dampness frequency value is not greater than the reference frequency value, it may be intentional.

[0256] The system will adopt different processing solutions for the above different situations.

[0257] S70112: When and only when the damp frequency value is greater than the preset reference frequency value, control the preset baffle device to block and protect the low-voltage branch box, and control the preset alarm device to sound an alarm.

[0258] In case of unintentional human error, a baffle device is provided on the outside of the low-voltage branch box to block water, and an alarm device is provided to sound an alarm.

[0259] In case of intentional human interference, an alarm device is set up to sound an alarm.

[0260] S7012: If the external humidity value is greater than the reference ambient humidity value, obtain the inner cavity water level value.

[0261] If the external humidity value is greater than the reference ambient humidity value, it means that there is heavy water or rainfall outside the low-voltage branch box, causing the water level to rise and enter the low-voltage branch box. The inner cavity water level value refers to the water level inside the low-voltage branch box. The inner cavity water level value is obtained by the water level sensor installed in the low-voltage branch box.

[0262] S70121: Determine whether the inner cavity water level value is greater than the warning water level value.

[0263] The warning water level value is a reference value used to measure whether the inner cavity water level value reaches the drainage standard. The warning water level value is a reference value set by technical personnel and will not be elaborated here.

[0264] S70122: When and only when the inner cavity water level value is greater than the warning water level value, control the preset drain valve to drain water and obtain the water level growth rate.

[0265] When the water level in the inner cavity does not reach the warning water level, there is no need to drain. When the water level in the inner cavity reaches the warning water level, the drain valve is opened, and the drain valve can discharge the water in the low-pressure branch box.

[0266] The water level growth rate refers to the speed at which the inner cavity water level value increases. The water level growth rate is calculated by the change in the inner cavity water level value over a period of time.

[0267] S70123: If the water level growth rate is greater than 0, the peak time is calculated according to the inner cavity water level value, the preset red line water level value and the water level growth rate.

[0268] If the water level growth rate is not greater than 0, it means that the water level value in the inner cavity is decreasing, the drainage is effective, and the system does not need to send an alarm to the background terminal.

[0269] If the water level growth rate is greater than 0, it means that the water level in the inner cavity is rising continuously. If it continues to rise, a fault will occur. The red line water level value refers to the water level value that will cause a low-voltage branch box fault. The red line water level value is a reference value set by the technicians and will not be elaborated here.

[0270] Peak time refers to the time when the inner cavity water level value in the low-pressure branch box reaches the red line water level value. Peak time can be calculated by the inner cavity water level value, the red line water level value and the water level growth rate.

[0271] S70124: Determine whether the peak time is greater than the preset estimated arrival time.

[0272] The estimated arrival time refers to the time it usually takes for staff to arrive at the location of the low-voltage branch box after receiving the terminal alarm.

[0273] S701241: If the peak time is greater than the estimated arrival time, the peak time is output to the terminal and an alarm is issued.

[0274] If the peak time is greater than the preset estimated arrival time, it means that before the staff arrives, the inner cavity water level value in the low-voltage branch box will not reach the red line water level value, which will not affect the normal use of the low-voltage branch box.

[0275] S701242: If the peak time is not greater than the estimated arrival time, the preset disconnecting device is controlled to cut off the power supply to the low-voltage branch box, and the peak time is output to the terminal and an alarm is issued.

[0276] If the peak time is not greater than the preset estimated arrival time, it means that before the staff arrives, the inner cavity water level value in the low-voltage branch box will exceed the red line water level value and cause a low-voltage branch box failure. At this time, the system can control the cut-off device to cut off the circuit, causing the low-voltage branch box to stop working.
