Description

Technical Field

[0001] The present invention relates to the field of electric power, and in particular to a detection method and a detection system for a cable trench cover. Background Art

[0002] In the construction of urban power grids, cable trenches are essential infrastructure in cable lines, and the status of their trench covers can directly affect the safe operation of cables.

[0003] In traditional technology, the inspection of cable trench covers mainly relies on manual labor. Due to the crushing of vehicles and pedestrians, or the erosion of the external environment, cable trench covers are often damaged or lost, or there are gaps between cable trench covers, which poses a hidden danger to the travel safety of pedestrians and vehicles, and causes damage to cable facilities.

[0004] In the prior art, the detection of cable trench covers mostly relies on manual inspection, but due to the wide distribution of cable trench facilities, this method is inefficient and prone to errors. It is difficult to comprehensively and accurately determine the status of the cover body and its adjacent cover bodies and the cable trench. Summary of the invention

[0005] The problem solved by the present invention is that it is difficult to accurately judge the state between a cover plate body and its adjacent cover plate bodies and a cable trench in the prior art.

[0006] To solve the above problems, the present invention provides a detection method for cable trench cover plates, the cable trench cover plates comprising: a plurality of cover plate bodies, the plurality of cover plate bodies being sequentially covered in the cable trench; a detection component, the detection component being used to detect the state between the cover plate body and two adjacent cover plate bodies and use them as a first state parameter and a second state parameter, and to detect the state between the cover plate body and the cable trench and use them as a third state parameter; a detection method is used to detect the cable trench cover plates, the detection method comprising: obtaining a first state parameter, a second state parameter and a third state parameter; judging whether the cover plate body is in an abnormal state according to the first state parameter, the second state parameter and the third state parameter; in the case where the cover plate body is not properly installed, judging the specific reason why the cover plate body is not properly installed; wherein the specific reason is any one of the following items or a combination thereof: judging whether there is a gap between the cover plate bodies according to the first state parameter and the second state parameter; judging whether the cover plate body has a position deviation according to the first state parameter, the second state parameter and the third state parameter; judging whether the cover plate body is misaligned up and down according to the third state parameter.

[0007] Compared with the prior art, the technical effect achieved by adopting the technical scheme is as follows: by introducing the detection component and the specific state parameters, the installation state of the cable trench cover is comprehensively and accurately detected. Specifically, the technical scheme of the present invention obtains the first state parameter, the second state parameter and the third state parameter through the detection component. These three parameters respectively reflect the distance between the cover body and its adjacent cover, and the distance between the cover body and the cable trench, so as to fully reflect the installation state of the cover body. Based on these parameters, the method of the present invention can accurately determine whether the cover body is in an abnormal state, and further determine the specific reasons when the cover body is not installed in place, such as whether there is a gap between the cover bodies, whether the cover body has position deviation, and whether the cover body is misaligned up and down. By automatically acquiring the state parameters, the tediousness and errors of manual inspection are avoided, and the detection efficiency is improved; at the same time, through the specific state parameters, the installation state of the cover body can be more accurately judged, and the accuracy of detection is improved. By obtaining multiple state parameters, the installation status of the cover body can be fully reflected, including the distance between the adjacent cover and the distance between the cable trench, etc., providing data support for refined management and maintenance. By timely discovering and handling installation problems of the cover body, such as gaps, position deviations, and up and down misalignments, safety accidents caused by improper installation of the cover can be effectively prevented, ensuring the normal use of the cable trench cover and the safety of personnel. In summary, the cable trench cover detection method of the present invention realizes comprehensive and accurate detection of the installation status of the cable trench cover by introducing detection components and specific state parameters, improves detection efficiency and accuracy, and provides a strong guarantee for the safe use of the cable trench cover.

[0008] Furthermore, based on the first state parameter, the second state parameter and the third state parameter, it is judged whether the cover body is in an abnormal state, including: when the first state parameter is equal to the first preset parameter, the second state parameter is equal to the second preset parameter and the third state parameter is equal to the third preset parameter, it is judged that the cover body is installed in place; when the first state parameter is not equal to the first preset parameter, the second state parameter is not equal to the second preset parameter or the third state parameter is not equal to the third preset parameter, it is judged that the cover body is not installed in place; wherein the first preset parameter, the second preset parameter and the third preset parameter are constants.

[0009] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the first preset parameter, the second preset parameter and the third preset parameter as the standard for the cover body to be installed in place, it can ensure that the judgment of the installation status of the cover body is more objective and accurate. These preset parameters are set according to the actual installation requirements and standards of the cable trench cover, and therefore can reflect whether the cover body has achieved the expected installation effect. By comparing whether the first state parameter, the second state parameter and the third state parameter are equal to the corresponding preset parameters, it can be quickly determined whether the cover body is installed in place. In summary, the adoption of this technical solution can achieve rapid and accurate judgment of the installation status of the cable trench cover, improve detection efficiency and accuracy, and also enhance the objectivity and reliability of the judgment results. This helps to promptly discover and deal with problems in the installation process of the cable trench cover, and ensure the safe operation of the cable trench.

[0010] Further, the first state parameter is the state between the cover plate body and the cover plate body adjacent to it along the first direction, and the second state parameter is the state between the cover plate body and the cover plate body adjacent to it along the second direction; according to the first state parameter and the second state parameter, judging whether there is a gap between the cover plate bodies, including: when the first state parameter is greater than the first preset parameter and the second state parameter is equal to the second preset parameter, judging that the cover plate body is in the first state; or when the first state parameter is equal to the first preset parameter and the second state parameter is greater than the second preset parameter, judging that the cover plate body is in the second state; when the cover plate body is in the first state, obtaining the state of the cover plate body adjacent to it along the first direction; when the state of the cover plate body adjacent to it along the first direction is the second state, judging that there is a gap between the cover plate body and the adjacent cover plate; or when the cover plate body is in the second state, obtaining the state of the cover plate body adjacent to it along the second direction; when the state of the cover plate body adjacent to it along the second direction is the first state, judging that there is a gap between the cover plate body and the adjacent cover plate; wherein the first direction is opposite to the second direction.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: when the state parameter is greater than the preset parameter, it indicates that there is a gap between the cover body and the adjacent cover body. Specifically, by judging whether the cover body is in the first state or the second state, it is judged whether there is a gap between the cover body and the cover body adjacent in the first direction or the second direction, and the state of the cover bodies adjacent in the direction is obtained. If the state of the adjacent cover bodies is opposite to the state between the cover bodies, it indicates that there is a gap between the cover body and the adjacent cover bodies.

[0012] Furthermore, the detection method also includes: when the first state parameter is greater than the first preset parameter and the second state parameter is greater than the second preset parameter, judging that the cover body is in the third state; when the cover body is in the third state, judging that the cover body is not properly covered.

[0013] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: if the distance between the cover body and the cover bodies adjacent to the two directions is greater than the preset distance, it means that the cover body is not in the correct position, and at this time it is judged that the cover body is not covered properly. By setting the preset parameters, it is possible to automatically judge whether the cover body is in the correct position. When the first state parameter and the second state parameter are both greater than the corresponding preset parameters, it can be judged that the cover body is in the third state, that is, the uncovered state. This judgment method is simple and direct, which improves the detection efficiency and also reduces the misjudgment caused by human factors. In addition, this technical solution also embodies high practicality and reliability. In actual applications, due to the influence of various factors, the cover body may be offset or not covered properly. By adopting this technical solution, these problems can be discovered in a timely manner, and corresponding measures can be taken to deal with them, thereby ensuring the safe operation of the cable trench.

[0014] Furthermore, the detection method also includes: when the cover body is in the first state, obtaining the state of the cover body adjacent to the cover body along the first direction; or when the cover body is in the second state, obtaining the state of the cover body adjacent to the cover body along the second direction; when the state of the cover body adjacent to the cover body along the first direction or the second direction is the third state, judging that the cover body is installed in place.

[0015] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: when judging whether the cover plate body is installed in place, not only the state of the cover plate body itself is considered, but also the state of the cover plate body adjacent to it along the first direction and the second direction is comprehensively considered. Avoid misjudgment that may be caused by single state parameter judgment. By obtaining the state of the cover plate body adjacent to the cover plate body along the first direction or the second direction, the mutual influence and correlation between adjacent cover plates can be further analyzed. When the adjacent cover plate body is in the third state, it means that the adjacent cover plate is not installed in place, indicating that the abnormal detection distance at the left and right ends of the cover plate body is caused by the adjacent cover plate not being installed in place. At this time, it can be judged that the current cover plate body is installed in place. The judgment method based on the state of adjacent cover plates improves the accuracy and reliability of the judgment.

[0016] Furthermore, based on the third state parameter, it is judged whether the cover body is misaligned up and down, including: when the third state parameter is not equal to the third preset parameter, judging that the cover body is in the fourth state; when the cover body is in the fourth state, judging that the cover body is misaligned up and down; or when the cover body is in the third state and the fourth state at the same time, judging that the cover body is not covered properly.

[0017] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by introducing the third state parameter, an accurate judgment of whether the cover body is misaligned up and down is realized. The third state parameter usually reflects the distance or position relationship between the cover body and the bottom of the cable trench or other reference surfaces. When the parameter is not equal to the preset third preset parameter, it can be judged that the cover body is in the fourth state, that is, the state of up and down misalignment. Through multiple state parameters of the cover body, its installation state can be more comprehensively evaluated. In addition to the third state parameter, other parameters such as the first state parameter and the second state parameter can also be combined for judgment to ensure an accurate evaluation of the installation state of the cover body. This comprehensive judgment method can avoid the misjudgment or missed judgment that may be caused by a single parameter judgment. In addition, the technical solution also considers the situation where the cover body is in the third state and the fourth state at the same time. When the cover body is not covered well and is misaligned up and down, it means that the up and down misalignment of the cover body is caused by not covering well.

[0018] Furthermore, the detection component includes: a first detection unit, which is used to detect the state between the cover body and the cover body adjacent to it along the first direction and use it as a first state parameter; a second detection unit, which is used to detect the state between the cover body and the cover body adjacent to it along the second direction and use it as a second state parameter; and a third detection unit, which is used to detect the state between the cover body and the cable trench and use it as a third state parameter.

[0019] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: through the first detection unit, the second detection unit and the third detection unit, they are respectively responsible for detecting the status between the cover body and the cover bodies adjacent to it in two different directions and the status between the cover body and the cable trench, thereby realizing comprehensive monitoring of the cover installation status.

[0020] Secondly, the setting of the first detection unit and the second detection unit enables us to obtain the status information of the cover body in two directions at the same time. This helps us to have a more comprehensive understanding of the installation of the cover body and avoid omissions or misjudgments. At the same time, by comparing the status parameters in the two directions, we can more accurately determine whether the cover body has problems such as offset and misalignment.

[0021] Furthermore, the detection component is at least one of the following: an infrared ranging unit, an electromagnetic sensor.

[0022] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: the technical solution of using infrared ranging units and electromagnetic sensors as detection components can realize accurate and reliable detection of the installation status of the cable trench cover, improves the detection efficiency and accuracy, and provides a strong guarantee for the safe operation of the cable trench.

[0023] Furthermore, the cover body includes: a power supply component, which is arranged on the cover body, and the power supply component includes a photovoltaic panel and a battery unit. The power supply component is electrically connected to the detection component for supplying power to the detection component.

[0024] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by arranging a power supply component on the cover body, autonomous power supply of the detection component is achieved, thereby avoiding the layout and management of external power supply lines and simplifying the installation and maintenance process.

[0025] The present invention also provides a detection system for a cable trench cover, the detection system comprising: an acquisition module: used to obtain a first state parameter, a second state parameter and a third state parameter; a judgment module: judging whether the cover body is installed in place according to the first state parameter, the second state parameter and the third state parameter; a state detection module: when the cover body is not installed in place, judging the specific reason why the cover body is not installed in place.

[0026] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0027] The cable trench cover detection method of the present invention realizes comprehensive and accurate detection of the installation status of the cable trench cover by introducing detection components and specific status parameters, improves detection efficiency and accuracy, and provides a strong guarantee for the safe use of the cable trench cover.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] S100: Acquire a first state parameter, a second state parameter, and a third state parameter;

[0036] S200: judging whether the cover body is in an abnormal state according to the first state parameter, the second state parameter and the third state parameter;

[0037] S300: when the cover plate body is not properly installed, determining a specific reason why the cover plate body is not properly installed;

[0038] Among them, the specific reasons are any one of the following or a combination thereof: judging whether there is a gap between the cover bodies according to the first state parameter and the second state parameter; judging whether there is a position deviation of the cover bodies according to the first state parameter, the second state parameter and the third state parameter; judging whether the cover bodies are misaligned up and down according to the third state parameter.

[0039] Specifically, each cover plate body is provided with a detection component. The detection component includes: a first detection unit, a second detection unit and a third detection unit. The first detection unit is responsible for measuring the distance between the current cover plate body and the cover plate body adjacent to one side thereof, and the distance is the first state parameter; the second detection unit measures the distance between the current cover plate body and the cover plate body adjacent to the other side thereof, and takes it as the second state parameter. The third detection unit measures the distance between the current cover plate body and the bottom of the cable trench, and takes it as the third state parameter.

[0040] Furthermore, based on the first state parameter, the second state parameter and the third state parameter, it is judged whether the cover body is in an abnormal state, including: when the first state parameter is equal to the first preset parameter, the second state parameter is equal to the second preset parameter and the third state parameter is equal to the third preset parameter, it is judged that the cover body is installed in place; when the first state parameter is not equal to the first preset parameter, the second state parameter is not equal to the second preset parameter or the third state parameter is not equal to the third preset parameter, it is judged that the cover body is not installed in place; wherein the first preset parameter, the second preset parameter and the third preset parameter are constants.

[0041] Specifically, after the cover body is installed in place, the control system detects in real time whether the first state parameter, the second state parameter, and the third state parameter are equal to the first preset parameter, the second preset parameter, and the third preset parameter, respectively. If all the state parameters are equal to the corresponding preset parameters, it is determined that the cover body is installed in place. If any state parameter is not equal to the corresponding preset parameter, it is determined that the cover body is not installed in place, and the specific reason is further checked.

[0042] Further, the first state parameter is the state between the cover plate body and the cover plate body adjacent to it along the first direction, and the second state parameter is the state between the cover plate body and the cover plate body adjacent to it along the second direction; according to the first state parameter and the second state parameter, judging whether there is a gap between the cover plate bodies, including: when the first state parameter is greater than the first preset parameter and the second state parameter is equal to the second preset parameter, judging that the cover plate body is in the first state; or when the first state parameter is equal to the first preset parameter and the second state parameter is greater than the second preset parameter, judging that the cover plate body is in the second state; when the cover plate body is in the first state, obtaining the state of the cover plate body adjacent to it along the first direction; when the state of the cover plate body adjacent to it along the first direction is the second state, judging that there is a gap between the cover plate body and the adjacent cover plate; or when the cover plate body is in the second state, obtaining the state of the cover plate body adjacent to it along the second direction; when the state of the cover plate body adjacent to it along the second direction is the first state, judging that there is a gap between the cover plate body and the adjacent cover plate; wherein the first direction is opposite to the second direction.

[0043] Specifically, if the first state parameter is greater than the first preset parameter, and the second state parameter is equal to the second preset parameter, it means that there is an abnormality in the distance between the cover body and the cover body adjacent to the first direction. At this time, the cover body is said to be in the first state. At this time, the state of the cover body adjacent to the first direction of the cover body is further checked. If the adjacent cover body is in the second state, it can be determined that there is a gap between the current cover body and the cover body adjacent to the first direction. Similarly, it can be determined whether there is a gap between the cover body and the cover body adjacent to the second direction.

[0044] Furthermore, the detection method also includes: when the first state parameter is greater than the first preset parameter and the second state parameter is greater than the second preset parameter, judging that the cover body is in the third state; when the cover body is in the third state, judging that the cover body is not properly covered.

[0045] Furthermore, the detection method also includes: when the cover body is in the first state, obtaining the state of the cover body adjacent to the cover body along the first direction; or when the cover body is in the second state, obtaining the state of the cover body adjacent to the cover body along the second direction; when the state of the cover body adjacent to the cover body along the first direction or the second direction is the third state, judging that the cover body is installed in place.

[0046] Specifically, if the cover body is in the first state or the second state, the state of the cover body adjacent to the cover body along the first direction or the second direction is obtained. If the state of the adjacent cover body is the third state, that is, the adjacent cover body is not covered properly, it means that the cover body is in the first state or the second state because the adjacent cover body is not covered properly.

[0047] Furthermore, based on the third state parameter, it is judged whether the cover body is misaligned up and down, including: when the third state parameter is not equal to the third preset parameter, judging that the cover body is in the fourth state; when the cover body is in the fourth state, judging that the cover body is misaligned up and down; or when the cover body is in the third state and the fourth state at the same time, judging that the cover body is not covered properly.

[0048] Furthermore, the detection component includes: a first detection unit, which is used to detect the state between the cover body and the cover body adjacent to it along the first direction and use it as a first state parameter; a second detection unit, which is used to detect the state between the cover body and the cover body adjacent to it along the second direction and use it as a second state parameter; and a third detection unit, which is used to detect the state between the cover body and the cable trench and use it as a third state parameter.

[0049] Furthermore, the detection component is at least one of the following: an infrared ranging unit, an electromagnetic sensor.

[0050] Specifically, by using the infrared distance measuring unit as a detection component, the distance between the cover body and its adjacent cover bodies and the cable trench can be accurately measured. The infrared distance measuring unit uses infrared signals for non-contact measurement, has the advantages of fast response speed and high measurement accuracy, and can accurately reflect the installation status of the cover body.

[0051] Specifically, the electromagnetic sensor is used to detect the installation status of the cover body. The electromagnetic sensor can detect the position and status of the metal parts between the cover body and the adjacent cover body or cable trench, and judge the installation status of the cover body by measuring the change of the electromagnetic field. This sensor has the characteristics of high sensitivity and good stability, and is suitable for cover installation detection in various complex environments.

[0052] Furthermore, the cover body includes: a power supply component, which is arranged on the cover body, and the power supply component includes a photovoltaic panel and a battery unit. The power supply component is electrically connected to the detection component for supplying power to the detection component.

[0053] Specifically, by setting up a power supply component consisting of a photovoltaic panel and a battery unit, a stable and continuous power supply can be provided for the detection component. The photovoltaic panel can convert solar energy into electrical energy, and the battery unit can store electrical energy and release it when needed, so that the detection component can work normally even in the absence of light or insufficient light. This improves the reliability of the system, reduces dependence on external power sources, and reduces the risk of detection failure caused by power supply problems.

[0054] The present invention also provides a cable trench cover detection system 100, such as Figure 2 As shown, the detection system 100 includes:

[0055] Acquisition module 110: used to acquire a first state parameter, a second state parameter and a third state parameter;

[0056] Determination module 120: Determine whether the cover body is installed in place according to the first state parameter, the second state parameter and the third state parameter;

[0057] The state detection module 130 is used to determine the specific reason why the cover plate body is not properly installed when the cover plate body is not properly installed.

[0058] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
