Description

Technical Field

[0001] The present invention relates to the technical field of cable trench systems, and in particular to a safety monitoring method and device for a cable trench system with an observation window. Background Art

[0002] As society develops and progresses, people are increasingly dependent on electricity. To ensure stable power output, cables are installed in cable trenches and covered with covers to protect the cables. The covers are opened manually at regular intervals to inspect the cables in the trenches.

[0003] However, there is at least one of the following problems in the related technology: because traditional inspection methods mainly rely on regular manual inspections, once an accident occurs to the cables in the cable trench, such as damage to the cables or abnormally high temperatures, they cannot be discovered in time, resulting in low efficiency in safety monitoring of the cables. Summary of the invention

[0004] The technical problem solved by the present invention is that since traditional inspection methods mainly rely on manual regular inspections, once an accident occurs to the cables in the cable trench, such as damage to the cables or abnormally high temperatures, it cannot be discovered in time, resulting in low efficiency in safety monitoring of the cables.

[0005] To solve the above problems, the present invention provides a safety monitoring method for a cable trench system with an observation window, wherein the cable trench system includes a cable trench structure, wherein a cable assembly consisting of a cable line group and a cable bracket is arranged in the cable trench structure; the safety monitoring method includes: controlling an inspection device arranged in an installation chamber of the cable trench structure to perform an inspection action on a prefabricated cover plate group covering the installation chamber, so as to obtain the covering information of the prefabricated cover plate group relative to the installation chamber; judging whether the cable trench structure is in an abnormal state according to the covering information; if so, controlling the inspection device to perform a monitoring action on the indoor environment in the installation chamber, and comparing the obtained environmental monitoring information of the corresponding indoor environment with the database of the cable trench system, so as to obtain a first comparison result; evaluating the potential hazard level of the installation chamber according to the first comparison result; and controlling the inspection device to send a corresponding early warning signal to the background terminal of the cable trench system according to the level number corresponding to the potential hazard level.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is: by setting up inspection equipment in the installation chamber, and using the inspection equipment to perform inspection actions in the installation chamber, the specific status information of the prefabricated cover plate group and the cable assembly can be obtained in time. It can be understood that when the inspection equipment identifies the presence of foreign matter in the installation chamber, it does not necessarily mean that it can pose a threat to the cable assembly. For example, when the foreign matter is a small insect such as a mosquito, it stays on the surface of the cable assembly and cannot cause harm to the cable assembly. On the contrary, if the creature is a rodent such as a mouse, there is a risk of biting through the skin of the cable wire in the cable assembly. Therefore, by analyzing the sealing information, it is used to determine whether the prefabricated cover plate group at the current moment has completed the reasonable sealing of the installation chamber, and effectively avoid the sealing gap formed between the prefabricated cover plate group and the installation chamber from being exposed for a long time, thereby causing the risk of foreign organisms entering the installation chamber along the sealing gap. In addition, combined with the acquired environmental monitoring information, it is used to more accurately assess the potential hazard level of the installation chamber, and avoid the situation in which foreign organisms invade the installation chamber without being discovered in time during the manual regular inspection of the cable assembly, resulting in the organisms being retained in the installation chamber after the prefabricated cover plate group is sealed, thereby posing a potential hazard to the cable assembly.

[0007] In one example of the present invention, whether the cable trench structure is in an abnormal state is determined based on the covering information, including: if not, controlling the inspection equipment to perform a cyclic monitoring action between the prefabricated cover plate group and the cable assembly, and obtaining the first surface information of the prefabricated cover plate group and the second surface information of the cable assembly; determining whether the corresponding prefabricated cover plate group and / or cable assembly meet the damage condition based on the first surface information and / or the second surface information; if so, controlling the inspection equipment to give a higher monitoring priority to the target damaged part than to the normal part; wherein the target damaged part is a part of either the prefabricated cover plate group or the cable assembly that meets the damage condition, and the normal part is a part of either that does not meet the damage condition.

[0008] In one example of the present invention, a cable line in a cable line group that meets a damage condition is defined as a first cable line, and a cable line that does not meet the damage condition is defined as a second cable line; the inspection equipment is controlled to have a higher monitoring priority for the target damaged part than for the normal part, including: the inspection equipment obtains by means of an infrared temperature sensing module whether there is an abnormal cable line with abnormal temperature in the cable line group; if so, determines whether the abnormal cable line meets the damage condition; if it is determined that the abnormal cable line meets the damage condition, controls the inspection equipment to have a higher monitoring priority for the abnormal cable line than for the remaining cable lines that do not meet the damage condition and / or have abnormal temperatures; if it is determined that the abnormal cable line does not meet the damage condition, controls the inspection equipment to have a higher monitoring priority for the abnormal cable line than for the first cable line.

[0009] In one example of the present invention, a trajectory line for the movement of an inspection device is provided in a cable trench structure, and the trajectory line extends along the length direction of the cable group; the inspection device includes a body movably connected to the trajectory line, and a functional body rotatably connected to the body; the inspection device provided in the installation chamber of the cable trench structure is controlled to perform an inspection action on the prefabricated cover plate group sealed to the installation chamber, including: controlling the inspection device to move to the starting position of the target prefabricated cover plate in the corresponding prefabricated cover plate group according to preset inspection requirements; acquiring a lower surface feature image of the target prefabricated cover plate and a gap feature image formed between other prefabricated cover plates arranged adjacent to the target prefabricated cover plate through a camera module of the functional body; judging whether the installation chamber is in an exposed state based on the lower surface feature image and the gap feature image; if so, controlling the inspection device to send the target coordinate information corresponding to the target prefabricated cover plate to the background terminal; if it is determined that the installation chamber is not in an exposed state, controlling the inspection device to move to the next target position according to the preset inspection route.

[0010] In one embodiment of the present invention, judging whether the installation chamber is in an exposed state according to the lower surface characteristic image and the gap characteristic image includes: if it is judged that the installation chamber is in an exposed state, judging whether the installation chamber meets the foreign body intrusion condition according to the gap characteristic image; if so, controlling the inspection device to establish a first inspection range centered on the position of the target prefabricated cover plate, and sending a first image of the cable assembly captured within the first inspection range to a background terminal; comparing the first image with a preset standard image to obtain a characteristic comparison image; judging whether the characteristic comparison image is related to the intrusion of foreign bodies. The intrusion traces are connected; wherein, the intrusion traces include the bite mark characteristics of the foreign object and the intrusion appearance characteristics of the foreign object that are mutually related to the intruding foreign object; if so, and when the intruding foreign object exists in the first inspection range by the inspection device, the infrared temperature sensing module of the inspection device is used to determine whether the intruding foreign object meets the survival conditions; if it is determined that the intruding foreign object does not meet the survival conditions, the coordinate information of the corresponding intruding foreign object is sent to the background terminal; if it is determined that the intruding foreign object meets the survival conditions, the inspection device is controlled to perform a following and driving action; wherein, the following and driving action includes establishing a driving and following range that is mutually related to the coordinate information of the intruding foreign object.

[0011] In one example of the present invention, it is determined whether the installation chamber meets the foreign body intrusion conditions based on the gap feature image, including: if not, determining whether the target prefabricated cover plate meets the preset safety matching conditions of the cover installation chamber based on the lower surface feature image; if it is determined that the preset safety matching conditions are not met, the inspection device sends the structural analysis information of the corresponding target prefabricated cover plate to the background terminal; if it is determined that the preset safety matching conditions are met, the inspection device is controlled to execute the preset inspection instructions.

[0012] In one example of the present invention, an invading foreign body is defined as a first animal; and the inspection equipment is controlled to perform a following and driving away action, including: controlling the onomatopoeia module of the inspection equipment to emit a second onomatopoeia signal simulating a second animal; wherein the second animal and the first animal are in a food chain superior-subordinate relationship, and the second animal is in a superior hunting position in the food chain superior relationship.

[0013] On the other hand, the present invention also provides a safety monitoring device for a cable trench system with an observation window, the cable trench system comprising a cable trench structure, in which a cable assembly consisting of a cable line group and a cable bracket is arranged; the safety monitoring device comprises: a control module, the control module being used to control an inspection device arranged in an installation chamber of the cable trench structure to perform an inspection action on a prefabricated cover plate group sealing the installation chamber, so as to obtain the sealing information of the prefabricated cover plate group relative to the installation chamber; a judgment module, the judgment module being used to judge whether the cable trench structure is in an abnormal state according to the sealing information; if so, the inspection device is controlled to perform a monitoring action on the indoor environment in the installation chamber, and the environmental monitoring information corresponding to the indoor environment obtained is compared with the database of the cable trench system, so as to obtain a first comparison result; an evaluation module, the evaluation module being used to evaluate the potential hazard level of the installation chamber according to the first comparison result; the control module controls the inspection device to send a corresponding early warning signal to the background terminal of the cable trench system according to the level number corresponding to the potential hazard level.

[0014] Compared with the prior art, the technical effect achieved by adopting this technical solution is: it can achieve the technical effect as in any of the above examples, which will not be repeated here.

[0015] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0016] By setting up inspection equipment in the installation chamber and using the inspection equipment to perform inspection actions in the installation chamber, the specific status information of the prefabricated cover plate group and the cable assembly can be obtained in time. It can be understood that when the inspection equipment identifies the presence of foreign matter in the installation chamber, it does not necessarily mean that it can pose a threat to the cable assembly. For example, when the foreign matter is a small insect such as a mosquito, it stays on the surface of the cable assembly and cannot pose a threat to the cable assembly. On the contrary, if the creature is a rodent such as a mouse, there is a risk of biting the cable wire skin in the cable assembly. Therefore, by analyzing the capping information, it is used to obtain whether the prefabricated cover plate group at the current moment has completed the reasonable capping of the installation chamber, whether it will cause a capping gap, and then cause the risk of external organisms entering the installation chamber along the capping gap. In addition, combined with the environmental monitoring information obtained, it is used to more accurately assess the potential hazard level of the installation chamber, so as to avoid the process of manual regular inspection of the cable assembly. Due to the invasion of the installation chamber by external organisms and not being discovered in time, the prefabricated cover plate group is capped, and the organism is retained in the installation chamber, thereby posing a potential hazard to the cable assembly.

[0022] 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.

[0023] See also Figure 1 , which is a flow chart of a safety monitoring method for a cable trench system with an observation window provided by an embodiment of the present invention. Specifically, the cable trench system includes a cable trench structure, in which a cable assembly consisting of a cable wire group and a cable bracket is arranged; the safety monitoring method includes:

[0024] Step S1, controlling the inspection equipment provided in the installation chamber of the cable trench structure to perform an inspection action on the prefabricated cover plate group sealed to the installation chamber, so as to obtain the sealing information of the prefabricated cover plate group relative to the installation chamber;

[0025] Step S2, judging whether the cable trench structure is in an abnormal state according to the capping information;

[0026] Step S3: If yes, the inspection device is controlled to perform monitoring on the indoor environment in the installation chamber, and the environmental monitoring information corresponding to the indoor environment obtained is compared with the database of the cable trench system to obtain a first comparison result;

[0027] Step S4, evaluating the potential hazard level of the installation chamber according to the first comparison result;

[0028] Step S5, controlling the inspection equipment to send a corresponding warning signal to the backend terminal of the cable trench system according to the level number corresponding to the potential hazard level.

[0029] By setting up inspection equipment in the installation chamber and using the inspection equipment to perform inspection actions in the installation chamber, the specific status information of the prefabricated cover plate group and the cable assembly can be obtained in time. It can be understood that when the inspection equipment identifies the presence of foreign matter in the installation chamber, it does not necessarily mean that it can pose a threat to the cable assembly. For example, when the foreign matter is a small insect such as a mosquito, it stays on the surface of the cable assembly and cannot pose a threat to the cable assembly. On the contrary, if the creature is a rodent such as a mouse, there is a risk of biting the cable wire skin in the cable assembly. Therefore, by analyzing the capping information, it is used to obtain whether the prefabricated cover plate group at the current moment has completed the reasonable capping of the installation chamber, whether it will cause a capping gap, and then cause the risk of external organisms entering the installation chamber along the capping gap. In addition, combined with the environmental monitoring information obtained, it is used to more accurately assess the potential hazard level of the installation chamber, so as to avoid the process of manual regular inspection of the cable assembly. Due to the invasion of the installation chamber by external organisms and not being discovered in time, the prefabricated cover plate group is capped, and the organism is retained in the installation chamber, thereby posing a potential hazard to the cable assembly.

[0030] Preferably, judging whether the cable trench structure is in an abnormal state according to the capping information includes:

[0031] If not, the inspection device is controlled to perform a cyclic monitoring action between the prefabricated cover plate group and the cable assembly, and obtain the first surface information of the prefabricated cover plate group and the second surface information of the cable assembly;

[0032] Determine whether the corresponding prefabricated cover plate group and / or cable assembly meets the damage condition according to the first surface information and / or the second surface information;

[0033] If so, the inspection equipment is controlled to give higher priority to the monitoring of the target damaged parts than to the monitoring of the normal parts;

[0034] Among them, the target damaged part is the part of either the prefabricated cover plate group or the cable assembly that meets the damage condition, and the normal part is the part of the two that does not meet the damage condition.

[0035] In a specific example, the prefabricated cover plate group includes a plurality of adjacent prefabricated cover plates arranged side by side, and the first surface information is data collected on the sides of two adjacent prefabricated cover plates close to each other. Specifically, the data includes the actual spacing formed between the two adjacent prefabricated cover plates. For ease of explanation, the two adjacent prefabricated cover plates mentioned above are defined as the first prefabricated cover plate and the second prefabricated cover plate, respectively. The actual spacing mentioned above is formed between the first prefabricated cover plate and the second prefabricated cover plate. Further, on the basis that the first prefabricated cover plate and the second prefabricated cover plate are not stacked on each other, if the actual spacing is formed when the structures of the first prefabricated cover plate and the second prefabricated cover plate are not damaged, then by judging the size between the actual spacing and the preset spacing, it is determined whether at least one of the first prefabricated cover plate and the second prefabricated cover plate is damaged. Specifically, when the actual spacing is greater than the preset spacing, it is determined that at least one of the first prefabricated cover plate and the second prefabricated cover plate is damaged, that is, it is determined that the damage condition is met. Among them, the preset spacing is set to meet the construction safety requirements. For example, when the actual spacing is greater than the preset spacing, a damaged gap may appear on the side of the first prefabricated cover plate close to the second prefabricated cover plate. Of course, a damaged gap may also appear on the side of the second prefabricated cover plate close to the first prefabricated cover plate.

[0036] Furthermore, the portion of the first prefabricated cover plate with the damaged notch can be defined as the first damaged portion, and the rest of the portion can be defined as the first normal portion; the portion of the second prefabricated cover plate with the damaged notch can be defined as the second damaged portion, and the rest of the portion can be defined as the second normal portion. Thus, the actual spacing formed between the first damaged portion and the second damaged portion is greater than the actual spacing formed between the first damaged portion and the second normal portion, and greater than the actual spacing formed between the second damaged portion and the first normal portion, and greater than the actual spacing formed between the first normal portion and the second normal portion.

[0037] Preferably, the cables in the cable group that meet the damage condition are defined as first cables, and the cables that do not meet the damage condition are defined as second cables;

[0038] The control inspection equipment has a higher priority for monitoring the target damaged parts than the normal parts, including:

[0039] The inspection equipment uses the infrared temperature sensing module to detect whether there are abnormal cables with abnormal temperatures in the cable group;

[0040] If so, determine whether the abnormal cable meets the damage condition;

[0041] If it is determined that the abnormal cable line meets the damage condition, the control inspection equipment will give higher priority to the monitoring of the abnormal cable line than the monitoring priority of other cables that do not meet the damage condition and / or have abnormal temperature;

[0042] If it is determined that the abnormal cable line does not meet the damage condition, the monitoring priority of the abnormal cable line by the control inspection device is higher than the monitoring priority of the first cable line.

[0043] Preferably, a track line for the inspection equipment to move is provided in the cable trench structure, and the track line extends along the length direction of the cable group; the inspection equipment includes a body movably connected to the track line, and a functional body rotatably connected to the body;

[0044] Controlling the inspection equipment in the installation chamber of the cable trench structure to perform inspection actions on the prefabricated cover plate group sealed to the installation chamber, including:

[0045] Control the inspection equipment to move to the starting position of the target prefabricated cover plate in the corresponding prefabricated cover plate group according to the preset inspection requirements;

[0046] Acquire, through the camera module of the functional body, a characteristic image of the lower surface of the target prefabricated cover plate and a characteristic image of the gap formed between other prefabricated cover plates arranged adjacent to the target prefabricated cover plate;

[0047] judging whether the installation chamber is in an exposed state according to the lower surface characteristic image and the gap characteristic image;

[0048] If yes, the inspection device is controlled to send the target coordinate information corresponding to the target prefabricated cover plate to the background terminal;

[0049] If it is determined that the installation chamber is not in an exposed state, the inspection device is controlled to move to the next target position according to a preset inspection route.

[0050] In another specific example, the obtained lower surface characteristic image is used to determine whether the target prefabricated cover plate and other prefabricated cover plates are stacked with each other. Specifically, when at least part of the structure of other prefabricated cover plates adjacent to the target prefabricated cover plate is placed below the target prefabricated cover plate, the lower surface characteristic image obtained at this time is a prefabricated surface characteristic image of the target prefabricated cover plate that is different from that of the target prefabricated cover plate in a normal matching condition.

[0051] Further, for ease of understanding, the two prefabricated cover plates that are stacked on each other can be defined as the third prefabricated cover plate and the fourth prefabricated cover plate. Take the case where at least part of the structure of the third prefabricated cover plate is stacked on the upper surface of the fourth prefabricated cover plate as an example. At this time, the lower surface feature information of the third prefabricated cover plate obtained by the inspection equipment at the preset position where the third prefabricated cover plate is placed is the third lower surface feature image, and the collected third lower surface feature image is compared with the standard lower surface feature image stored in the database, and then the placement of the third prefabricated cover plate is judged according to the comparison result. For example, if the preset position is completely covered as the standard, when at least part of the structure of the third prefabricated cover plate is stacked on the fourth prefabricated cover plate, the area ratio of the third lower surface feature image covering the preset position is P1, and the area ratio of the normal placement of the third prefabricated cover plate at the preset position is P0. Therefore, when P1 / P0<K collected by the inspection equipment, it means that the placement of the third prefabricated cover plate at the preset position is abnormal, such as the stacking mentioned above. For example, P1 / P0 may be 0.9, K is a preset value, and K may be 1.

[0052] Preferably, judging whether the installation chamber is in an exposed state according to the lower surface characteristic image and the gap characteristic image includes:

[0053] If it is determined that the installation chamber is in an exposed state, whether the installation chamber meets the foreign body intrusion condition is determined based on the gap feature image;

[0054] If so, the inspection device is controlled to establish a first inspection range centered on the location of the target prefabricated cover plate, and a first image of the cable assembly captured within the first inspection range is sent to the backend terminal;

[0055] Comparing the first image with a preset standard image to obtain a feature comparison image;

[0056] Determine whether there are intrusion traces associated with the intruding foreign body in the feature comparison image; wherein the intrusion traces include bite mark features of the foreign body and appearance features of the intruding foreign body that are associated with the intruding foreign body;

[0057] If so, and if there is an intruding foreign object within the first inspection range of the inspection device, the infrared temperature sensing module of the inspection device is used to determine whether the intruding foreign object meets the survival condition;

[0058] If it is determined that the intruding foreign object does not meet the survival condition, the coordinate information of the corresponding intruding foreign object is sent to the background terminal;

[0059] If it is determined that the intruding foreign object meets the survival conditions, the inspection equipment is controlled to perform the follow-up and expulsion action;

[0060] The following and driving action includes establishing a driving and following range that is associated with the coordinate information of the invading foreign object. The driving and following range is a range that covers the coordinate information. If the invading foreign object is a living body, the acquired coordinate information is affected by the activity trajectory of the invading foreign object and changes dynamically.

[0061] Preferably, judging whether the installation chamber meets the foreign body intrusion condition according to the gap characteristic image includes:

[0062] If not, judging whether the target prefabricated cover plate meets the preset safety matching conditions of the cover installation chamber according to the lower surface characteristic image;

[0063] If it is determined that the preset safety matching conditions are not met, the inspection equipment will send the structural analysis information of the corresponding target prefabricated cover to the background terminal;

[0064] If it is determined that the preset safety coordination conditions are met, the inspection equipment is controlled to execute the preset inspection instructions.

[0065] Preferably, the invading foreign body is defined as the first animal; and the inspection device is controlled to perform a following and driving action, including:

[0066] Controlling the onomatopoeia module of the inspection equipment to send out a second onomatopoeia signal simulating a second animal;

[0067] Among them, the second animal and the first animal are in a food chain superior-subordinate relationship, and the second animal is in a superior hunting position in the food chain superior relationship.

[0068] On the other hand, see Figure 2 , which is a schematic diagram of the module connection of a safety monitoring device 100 for a cable trench system with an observation window according to an embodiment of the present invention. Specifically, the cable trench system includes a cable trench structure, in which a cable assembly consisting of a cable line group and a cable bracket is provided; the safety monitoring device 100 includes, for example, a control module 10, a judgment module 20 and an evaluation module 30. The control module 10 is used to control the inspection equipment provided in the installation chamber of the cable trench structure to perform an inspection action on the prefabricated cover plate group sealed to the installation chamber, so as to obtain the sealing information of the prefabricated cover plate group relative to the installation chamber; the judgment module 20 is used to judge whether the cable trench structure is in an abnormal state according to the sealing information;

[0069] If so, the inspection device is controlled to perform a monitoring action on the indoor environment in the installation chamber, and the environmental monitoring information corresponding to the indoor environment obtained is compared with the database of the cable trench system to obtain a first comparison result;

[0070] The evaluation module 30 is used to evaluate the potential hazard level of the installation chamber according to the first comparison result; the control module 10 controls the inspection equipment to send a corresponding warning signal to the background terminal of the cable trench system according to the level number corresponding to the potential hazard level.
