Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring, and in particular, to a safety monitoring method, device, and storage medium applied to a cable tunnel. Background Art

[0002] With the acceleration of the urbanization process, the underground cable tunnel, as an important infrastructure for urban power transmission, its safe operation is crucial. During the long-term operation of cables, due to factors such as load changes, environmental temperature fluctuations, and insulation aging, overheating is likely to occur. In severe cases, it may trigger fire accidents, causing huge economic losses and social impacts. Therefore, real-time and effective safety monitoring of the cable tunnel, especially the monitoring and control of the cable surface temperature, has become the key to ensuring the safe operation of the cables.

[0003] Traditional cable temperature monitoring methods mainly rely on manual inspections or fixed temperature sensors. Manual inspections have problems such as low efficiency, poor real-time performance, and difficulty in covering all areas; while fixed temperature sensors have limitations in installation positions, limited monitoring ranges, and difficulty in flexible adjustment. In addition, the internal environment of the cable tunnel is complex, the space is narrow and long, and the air circulation is not smooth, which is likely to form local high-temperature areas. Traditional temperature monitoring methods are difficult to meet the comprehensive and accurate monitoring requirements. Summary of the Invention

[0004] The technical problem solved by the present invention is that traditional cable temperature monitoring methods mainly rely on manual inspections or fixed temperature sensors. Manual inspections have problems such as low efficiency, poor real-time performance, and difficulty in covering all areas; while fixed temperature sensors have limitations in installation positions, limited monitoring ranges, and difficulty in flexible adjustment. In addition, the internal environment of the cable tunnel is complex, the space is narrow and long, and the air circulation is not smooth, which is likely to form local high-temperature areas. Traditional temperature monitoring methods are difficult to meet the comprehensive and accurate monitoring requirements.

[0005] To solve the above problems, the present invention provides a safety monitoring method applied to a cable tunnel. The internal space of the cable tunnel is provided with a comprehensive support for installing cable components, and the comprehensive support is fixedly connected to the side wall of the cable tunnel; the internal space is also provided with an inspection trolley, and the inspection trolley is provided with a temperature sensor for obtaining the surface temperature of the cable components; the safety monitoring method includes: controlling the inspection trolley to perform an inspection action on the area where the cable components are located to obtain the surface temperature; judging whether to operate the refrigeration system provided in the internal space according to the surface temperature; if so, adjusting the refrigeration temperature and the air outlet angle of the refrigeration system according to the surface temperature and the indoor environment temperature of the internal space.

[0006] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By setting up a movable inspection trolley equipped with a high-precision temperature sensor, real-time and comprehensive monitoring of the surface temperature of the cable assembly is realized; combined with the refrigeration system inside the cable tunnel, according to the monitored surface temperature data and the indoor ambient temperature, the operating parameters of the refrigeration system are dynamically adjusted to achieve precise control of the temperature inside the cable tunnel, effectively preventing safety accidents caused by overheating of the cable assembly and ensuring the safe operation of the cable tunnel.

[0007] In an example of the present invention, adjusting the refrigeration temperature and the air outlet angle of the refrigeration system according to the surface temperature and the indoor ambient temperature of the internal space includes: obtaining the actual skin information of the cable assembly through the inspection trolley; wherein, the actual skin information includes the surface temperature and the surface damage condition which are interrelated; judging whether the cable assembly is in a normal operating state according to the actual skin information; if so, judging whether it is necessary to adjust the air outlet angle according to the surface damage condition and the air outlet temperature at the air outlet of the refrigeration system; if it is determined that the air outlet angle needs to be adjusted, controlling the air outlet angle of the refrigeration system to avoid the area where the cable assembly is located.

[0008] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Specifically, during the long-term operation in combination with the actual operating conditions of the cable assembly, heat will be generated, resulting in the surface temperature of the cable assembly being higher than the surrounding ambient temperature. Although the refrigeration system can play a role in cooling the cable assembly, it is inevitable that condensation will occur at the air outlet, and under the action of the air outlet, the situation of condensation splashing will occur. Therefore, when it is determined that there is a risk of possible condensation, in combination with the surface damage condition of the cable assembly, by adjusting the air outlet angle to avoid the position of the cable assembly, it is possible to prevent the condensed water from splashing on the surface of the cable assembly, thereby affecting the insulation performance of the cable assembly and shortening the service life of the cable assembly.

[0009] In an example of the present invention, judging whether it is necessary to adjust the air outlet angle according to the surface damage condition and the air outlet temperature at the air outlet of the refrigeration system includes: if it is determined that the air outlet angle does not need to be adjusted, controlling the air outlet angle of the refrigeration system to be aligned with the area where the cable assembly is located.

[0010] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Specifically, when there is no risk of condensation at the air outlet of the refrigeration system, the air outlet angle is aligned with the area where the cable assembly is located to further improve the refrigeration effect on the cable assembly.

[0011] In an example of the present invention, if it is determined that the air outlet angle needs to be adjusted, the air outlet angle of the refrigeration system is controlled to avoid the area where the cable assembly is located, including: judging whether the condensation condition is satisfied according to the air outlet temperature; if so, obtaining the condensation splash information according to the swing angle of the air deflector of the refrigeration system and the air outlet air duct; controlling the inspection trolley to perform a cleaning action according to the condensation splash information.

[0012] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: Specifically, the inspection trolley timely cleans the water stains splashed by condensation, avoiding the evaporation of the water stains from affecting the environmental humidity of the internal space.

[0013] In an example of the present invention, a distance sensor is provided at the air outlet of the refrigeration system; controlling the inspection trolley to perform a cleaning action according to the condensation splash information includes: obtaining the water stain splash area according to the air outlet air duct and the swing angle; wherein, the water stain splash area attached to the surface of the cable assembly is defined as the first splash area, and the water stain splash area attached to the ground in the internal space is defined as the second splash area; obtaining the first distance formed between the first splash area and it through the distance sensor; adjusting the output power of the refrigeration system according to the first distance and the surface temperature, and adjusting the air outlet to face the direction of the first splash area for the first duration; controlling the inspection trolley to move to the second splash area to perform a cleaning action; judging whether the cleaning duration of the inspection trolley performing the cleaning action meets the first preset time; if so, obtaining the water stain residue amount in the second splash area at this time; judging whether the water stain residue amount meets the condition for extending the cleaning; if not, controlling the inspection trolley to perform an inspection action according to the preset conditions.

[0014] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The inspection trolley is set with a set cleaning duration for performing the cleaning action. Once the accumulated water volume in the water stain splash area is too large, the inspection trolley cannot complete the cleaning of the water stains within the originally set first preset duration. Therefore, at this time, it is necessary to extend the cleaning duration to ensure the successful removal of the water stains and ensure the cleanliness of the internal space of the cable gallery.

[0015] In an example of the present invention, judging whether the water stain residue amount meets the condition for extending the cleaning includes: if so, the inspection trolley sends the feedback information related to the water stain residue amount to the refrigeration system; controlling the refrigeration system to increase the air outlet temperature and increase the air outlet air duct according to the feedback information; sending an extension instruction to the inspection trolley to extend the first preset duration.

[0016] In an example of the present invention, the cable assembly is a distributed optical cable structure; judging whether the cable assembly is in a normal operating state according to the actual skin information includes: if not, obtaining the position coordinates of the abnormal operation of the distributed optical cable structure according to the control terminal; controlling the inspection trolley to move to the position of the position coordinates, and obtaining the abnormal skin information of the distributed optical cable structure associated with the position coordinates through the temperature sensor and the camera module of the inspection trolley; when the surface damage condition in the abnormal skin information meets the preset exposure risk, sending a maintenance signal to the control terminal; controlling the air outlet angle to avoid the area corresponding to the abnormal skin information of the distributed optical cable structure; when the surface damage condition in the abnormal skin information does not meet the preset exposure risk, and the surface temperature in the abnormal skin information is higher than the preset safety temperature, controlling the air outlet angle to aim at the area corresponding to the abnormal skin information of the distributed optical cable structure, and / or increasing the air outlet gear.

[0017] Compared with the prior art, the technical effects achieved by adopting this technical solution: further improve the operation safety and reliability of the cable assembly.

[0018] In an example of the present invention, when different cable assemblies simultaneously present abnormal operation and normal operation, the priority of the inspection trolley to perform inspection actions on the cable assemblies in abnormal operation is higher than that of the cable assemblies in normal operation.

[0019] Compared with the prior art, the technical effects achieved by adopting this technical solution: through the priority scheduling mechanism, ensure that the inspection trolley preferentially processes the cable assemblies with abnormal operation, and further improve the monitoring efficiency and safety.

[0020] On the other hand, the embodiment of the present invention also provides a safety monitoring device applied to a cable tunnel. The internal space of the cable tunnel is provided with a comprehensive support for installing a cable assembly, and the comprehensive support is fixedly connected to the side wall of the cable tunnel; the internal space is also provided with an inspection trolley, and the inspection trolley is provided with a temperature sensor for obtaining the surface temperature of the cable assembly; the safety monitoring device includes: a control module for controlling the inspection trolley to perform inspection actions on the area where the cable assembly is located to obtain the surface temperature; a judgment module for judging whether to operate the refrigeration system provided in the internal space according to the surface temperature; an adjustment module for adjusting the refrigeration temperature and the air outlet angle of the refrigeration system according to the surface temperature and the indoor environment temperature of the internal space when it is determined that the refrigeration system in the internal space is operating.

[0021] Compared with the prior art, the technical effects achieved by adopting this technical solution: can achieve the technical effects in any of the above examples, which will not be elaborated here.

[0022] In another aspect, the present invention further provides a storage medium for storing a computer program, which is loaded by a processor to execute the security monitoring method of any of the above embodiments.

[0024] After adopting the technical solution of the present invention, the following technical effects can be achieved: (1) By setting a movable inspection trolley equipped with a high-precision temperature sensor, real-time and comprehensive monitoring of the surface temperature of the cable assembly is realized; combined with the refrigeration system inside the cable duct, according to the monitored surface temperature data and the indoor ambient temperature, the operating parameters of the refrigeration system are dynamically adjusted to achieve precise control of the temperature inside the cable duct, effectively preventing safety accidents caused by overheating of the cable assembly and ensuring the safe operation of the cable duct; (2) Considering the actual operating conditions of the cable assembly, heat is generated during long-term operation, resulting in its surface temperature being higher than the surrounding ambient temperature. Although the refrigeration system can play a role in cooling the cable assembly, it is inevitable that condensation occurs at the air outlet, and under the action of the air outlet, condensation splashing occurs. Therefore, when it is determined that there is a risk of condensation, combined with the surface damage condition of the cable assembly, the position of the cable assembly is avoided by adjusting the air outlet angle, preventing the condensed water from splashing on the surface of the cable assembly, thereby affecting the insulation performance of the cable assembly and shortening the service life of the cable assembly.
