Description

Technical Field

[0001] This application belongs to the field of power equipment technology, specifically relating to a danger warning device, method and equipment for underground buried cables. Background Technology

[0002] Underground cables are an important power transmission system that efficiently delivers electricity from power plants to users. They effectively mitigate obstacles and interference in power lines, making power transmission safer and more reliable. Underground cables also effectively avoid spatial and environmental impacts associated with power lines, thus protecting the environment. However, when laying underground cables, it is necessary to warn pedestrians of their presence to prevent accidents from contact and to avoid damage to the cables caused by contact.

[0003] However, currently, warning signs are placed around underground cables to alert pedestrians of their presence. However, these signs cannot be placed along the entire length of the cable, and are instead placed at intervals. This can lead to accidents as pedestrians may not see the signs and approach the cables, while also causing some damage to the underground cables.

[0004] Therefore, how to detect whether pedestrians are passing by in real time within the length of underground cable laying, so as to prompt pedestrians to stay away from underground cables, ensure pedestrian safety and prevent damage to underground cables, is an urgent problem to be solved in this field. Summary of the Invention

The aim is to solve the problem in existing technologies that cannot detect in real time whether underground cables are buried where pedestrians pass, thus failing to identify potential hazards and provide real-time warnings to pedestrians to stay away from underground cables. This can lead to pedestrians approaching the cables without seeing warning signs, resulting in accidents and damage to the underground cables. The aforementioned hazard warning device for underground buried cables compares the real-time location of pedestrians with the cable burial location to determine alarm information and uses a speaker positioned opposite to the pedestrian to sound an alarm. This allows for more accurate detection of pedestrians approaching the cable burial location and timely alarm issuance, making it easier for pedestrians to hear the alarm and thus better protecting the safety of both pedestrians and the cables.

[0061] The following description, in conjunction with the accompanying drawings, details the hazard warning device, method, and equipment for underground buried cables provided in this application through specific embodiments and application scenarios.

[0062] Example 1

[0063] Figure 1 This is a schematic diagram of the structure of the hazard warning device for underground buried cables provided in Embodiment 1 of this application. Figure 1 As shown, it specifically includes the following:

[0064] Vibration detection module 101 is used to acquire vibration information when a pedestrian passes by through a sensor;

[0065] The location recognition module 102 is used to determine the real-time location of the pedestrian based on the intensity of the vibration information;

[0066] The comparison module 103 is used to compare the real-time location of the pedestrian with the cable burial location to determine whether they overlap or whether they are within a preset range of the cable burial location.

[0067] The identification module 104 generates alarm information according to pre-set alarm rules when there is overlap or within a preset range;

[0068] The alarm module 105 includes at least two speakers, which are located at two points directly above the cable burial location and are positioned opposite each other corresponding to the cable burial direction. The alarm module is used to receive alarm information, identify the target speaker, and play the alarm information through the target speaker.

[0069] Firstly, this solution can be used in scenarios where sensors acquire vibration information when pedestrians pass by and send it to a smart terminal for processing. The smart terminal determines the pedestrian's location based on the vibration information and compares it with the cable burial location. If the pedestrian's location coincides with the cable burial location or is within a preset range, an alarm message is generated and transmitted to a speaker, which then plays the alarm message to the pedestrian.

[0070] Based on the above-mentioned usage scenarios, it is understood that the implementing entity of this application can be a hazard alarm device for underground buried cables that integrates the acquisition of vibration information when pedestrians pass by, the analysis of vibration information, the generation of alarm information, and the playback of alarm information. No further limitations are imposed here.

[0071] In this scheme, the sensor can be an accelerometer. The accelerometer can detect the vibration information of a person walking by detecting and recording the vibrations generated on the ground when a person walks. The vibration information can include the person's gait, speed, frequency, direction and acceleration.

[0072] When a pedestrian passes by, the accelerometer can measure and detect the pedestrian's stride and the changes in body acceleration during walking. It calculates the pedestrian's walking speed based on the acceleration changes during stride; measures the pedestrian's stride frequency by detecting changes in the pedestrian's center of gravity; measures the pedestrian's walking direction by measuring the acceleration and deceleration during each step; and measures gait by detecting changes in acceleration during leg movement and when the legs land. By detecting and calculating the above information, vibration information about human walking is obtained.

[0073] The real-time position of a pedestrian can be represented by their three-dimensional spatial coordinates, in the form of (X, Y, Z). The coordinate system of these three-dimensional coordinates can be predetermined based on the cable's burial location. The origin can be the midpoint between the start and end points of the cable burial. The unit length can be set to 1m. The positive and negative x-axis directions can be defined according to the transverse direction of the cable burial. The transverse direction from the origin to the cable's operating end is the positive x-axis, and the transverse direction from the origin to the cable's operating source end is the negative x-axis. The longitudinal direction perpendicular to the cable's burial location is the positive y-axis, and the longitudinal direction perpendicular to the cable's burial location is the negative y-axis. The direction above the cable is the positive z-axis, and the direction below the cable is the negative z-axis. For example, if the cable is 50m long and buried 2m deep underground, and a pedestrian is 20m away from the origin in the positive transverse direction and 3m away from the origin in the positive longitudinal direction, then the vibration location can be represented as (+20, +3, +2).

[0074] When using an accelerometer to acquire vibration information as a pedestrian passes by, this vibration information can be transmitted to a smart terminal via wireless communication technology. The smart terminal can then identify the pedestrian's real-time location based on the magnitude and frequency of the vibration signal transmitted by the accelerometer. The specific steps are as follows:

[0075] 1. Calculate the velocity and distance of the vibration signal through integration;

[0076] 2. Calculate the real-time location of the pedestrian based on the speed and distance of the vibration signal;

[0077] 3. When the pedestrian makes their next move, the vibration information of the pedestrian's next passage will be sent to the smart terminal;

[0078] 4. The smart terminal continuously repeats steps 1-2 to determine the real-time location information of pedestrians and monitors their real-time location in real time.

[0079] Wireless communication refers to long-distance transmission communication between multiple nodes without transmission through conductors or cables. Wireless communication can be carried out using radios, radio waves, etc.

[0080] Based on the above technical solutions, optionally, the location identification module 102 is further used for:

[0081] Identify the stride length and direction of movement of pedestrians as they pass by;

[0082] Based on the stride information and the direction of movement information, determine the movement data of the pedestrian as they pass by;

[0083] Accordingly, the comparison module 103 is further configured to:

[0084] Determine the path duration of a pedestrian traversing a preset range of cable burial locations based on the aforementioned motion data;

[0085] Accordingly, the identification module 104 is further configured to:

[0086] If the paths overlap or fall within a preset range, and the path duration reaches a preset time length, then an alarm message is generated according to the pre-set alarm rules.

[0087] In this scheme, the stride information of a pedestrian can be the distance from the landing of one foot to the landing of the other foot, which can be used to measure the pedestrian's walking speed.

[0088] Pedestrian movement direction information can include directions close to and away from the cable burial location.

[0089] Visual detection technology can be used to identify the stride length and direction of movement of pedestrians. For example, a camera can be used to capture the posture of pedestrians while they are walking, and then computer vision technology can be used to analyze the data to obtain the stride length and direction of movement. Sensor technology can also be used to identify the stride length and direction of movement of pedestrians. For example, ground sensors can be installed to collect ground feedback signals as pedestrians move, thereby obtaining the stride length and direction of movement. In this solution, ground sensors can be used to identify the stride length and direction of movement information of pedestrians as they pass by.

[0090] Motion data can include the speed and direction of a pedestrian's movement. The speed can be determined by the pedestrian's stride length, specifically through gait analysis. Gait analysis is a technique that identifies a walker's speed and gait by analyzing and measuring stride length, stride frequency, stride duration, and gait elements. Once ground sensors detect a pedestrian's stride length and direction of movement, this information can be transmitted to a smart terminal via wireless communication. The smart terminal can then use gait analysis to determine the pedestrian's speed based on the stride length information and combine this with the direction of movement information to determine the pedestrian's motion data.

[0091] The travel time can be the time required for a pedestrian to traverse a preset range of the cable burial location. Once the smart terminal determines the pedestrian's movement data, it can calculate the travel time within the preset range by combining the pedestrian's real-time location with the preset range of the cable burial location. Specifically, if the pedestrian has not reached the preset cable burial location but is moving towards it, the smart terminal will calculate the total distance the pedestrian travels across the cable burial location based on the pedestrian's real-time location, and then determine the travel time within the preset range of the cable burial location using the following formula:

[0092] Travel time = Total distance traveled by pedestrians across the cable laying location ÷ Pedestrian speed

[0093] If a pedestrian is at a preset cable burial location and is moving away from that location, the smart terminal can calculate the remaining total distance the pedestrian will travel through the cable burial location based on the pedestrian's real-time location. Then, the path duration for the pedestrian to traverse the preset range of the cable burial location can be determined using the following formula:

[0094] Travel time = Total distance the pedestrian still needs to travel past the cable laying location ÷ Pedestrian speed

[0095] For example, when a pedestrian is at the predetermined location of a buried cable, and the direction of movement is away from the cable location, if the cable is 60 meters long and the pedestrian needs to move another 20 meters away from the cable location, and the pedestrian's speed is 1.6 m / s, then the time it takes for the pedestrian to travel through the predetermined range of the cable location is 12.5 seconds. The calculation process is as follows:

[0096] 20 ÷ 1.6 = 12.5

[0097] When the travel time reaches a preset duration, it is considered a danger for pedestrians to pass through this area, and an alarm message needs to be generated to remind pedestrians that there is an underground cable buried there and they should stay away from this location. In this solution, the preset duration can be set to 10 seconds. Then, when the pedestrian's real-time location coincides with or is within the preset range of the cable burial location, and the travel time calculated by the smart terminal reaches the preset duration, the smart terminal can call the pre-set alarm rules to generate an alarm message.

[0098] In this solution, by acquiring the movement data of pedestrians and calculating the travel time based on the movement data, it is possible to determine whether to generate alarm information. This allows for more accurate detection of whether pedestrians have passed through specific cable burial locations and whether there are any dangerous situations. Alarm information can then be used to alert pedestrians, thereby improving safety precautions and warning capabilities.

[0099] The distance between the starting and ending points of cable burial can be considered the cable burial location. The predetermined range of the cable burial location can be a portion of the longitudinal area of ​​the cable burial location; for example, the area within 3 meters before and after the cable burial location can be defined as the predetermined range. For safety reasons, pedestrians on the road within a few meters of the cable's longitudinal distance may accidentally step on it; therefore, warning signs should be placed to prevent potential accidents.

[0100] The cable burial location information and the preset range information of the cable burial location can be stored in the smart terminal in advance. When the real-time location of a pedestrian is determined in the smart terminal, the smart terminal automatically calls up the cable burial location information and the preset range information of the cable burial location, and compares the real-time location of the pedestrian with the cable burial location and the preset range of the cable burial location, so as to determine whether the real-time location of the pedestrian coincides with the cable burial location or whether it is within the preset range of the cable burial location.

[0101] Pre-set alarm rules can establish different alarm levels and corresponding alarm strategies based on the relative distance between the pedestrian's real-time location and the cable burial location, or a preset range between the two locations. Specifically, when the pedestrian's real-time location coincides with the cable burial location, the alarm level and alarm strategy can be set to the highest level. When the pedestrian's real-time location is within the preset range of the cable burial location, the closer they are to the cable, the higher the alarm level and alarm strategy level; the farther they are from the cable, the lower the alarm level and alarm strategy level. Correspondingly, if the preset range is 3 meters before and after the cable burial location, the alarm level and alarm strategy level can be divided into 4 levels, with each level representing a 1-meter interval. Level 1 is the lowest level, and level 4 is the highest level; that is, level 1 is when the pedestrian's real-time location is 3 meters longitudinally away from the cable, and level 4 is when the pedestrian's real-time location coincides with the cable burial location.

[0102] Alarm messages can be messages reminding pedestrians to stay away from cables, and can be presented in the form of text, sound, or graphics. Alarm rules can be pre-stored in the smart terminal. When the smart terminal detects that a pedestrian's real-time location coincides with the cable's burial location or is within a preset range, it can call the pre-set alarm rules to generate an alarm message.

[0103] Based on the above technical solutions, optionally, the identification module 104 is further used for:

[0104] If the objects overlap or fall within a preset range, a projection command is generated.

[0105] The device further includes:

[0106] An electronic fence projection module is used to receive the projection command and project the electronic fence according to pre-configured projection parameters; wherein the projection parameters include at least one of projection position, projection content, and projection color.

[0107] In this solution, the projection instruction can be a notification generated by a smart terminal, prompting pedestrians to leave the area where underground cables are located.

[0108] An electronic fence can be a three-dimensional virtual fence that projects a virtual, visual fence on-site to warn pedestrians that the fenced area is a hazard zone where underground cables are buried and that they should leave as soon as possible.

[0109] Projection parameters refer to the parameters used in projection transformation, including at least one of projection position, projection content, and projection color. The projection position can be the location and width of the projection display. The projection position can be set between two speakers. For example, if the cable is 60m long and two speakers are placed opposite each other every 20m, when it is necessary to warn pedestrians 30m from the cable's burial point that an underground cable exists and they should leave immediately, the projection position could be between the two speakers at a distance of 20m to 40m, with a projection width of 20m. In this solution, the projection content can be set to "An underground cable exists here; please leave immediately," and the projection color can be set to red. Pre-testing can be conducted to ensure pedestrians can clearly see the projected text. After this, the projection position, content, and color can be set in the electronic fence's database, allowing for direct retrieval of these parameters when the electronic fence needs to display a projection.

[0110] When a pedestrian's real-time location coincides with the cable's burial location or falls within a preset range, the smart terminal can generate a projection command via computer software and send it to the electronic fence via a wireless or wired network. The sent projection command can be customized according to the electronic fence's configuration and security requirements to ensure its proper functioning within the electronic fence.

[0111] After receiving the projection command transmitted by the smart terminal, the electronic fence automatically calls the pre-configured projection parameters in the electronic fence database to project and display the electronic fence, so as to remind pedestrians that there are underground cables here and to leave as soon as possible.

[0112] In this solution, an electronic fence is set up, and when the real-time location of a pedestrian coincides with the location of the buried cable or is within a preset range, a projection display is made to remind pedestrians that there is an underground cable and to leave as soon as possible. This makes it easier for pedestrians to see the warning, thereby better protecting the safety of both pedestrians and cables.

[0113] Based on the above technical solutions, optionally, the identification module 104 is further used for:

[0114] In cases where the pedestrians overlap or fall within a preset range, the vibration information is used to determine whether the pedestrian belongs to a specific type of interest.

[0115] If so, determine the alarm control parameters after generating the alarm information;

[0116] Accordingly, the alarm module is also used for:

[0117] The system receives alarm information and alarm control parameters, determines the operating parameters of the target speaker based on the alarm control parameters, and plays the alarm information through the target speaker based on the operating parameters.

[0118] This plan includes special attention for the elderly and children, as both have lower self-protection capabilities and are more vulnerable to external harm. Therefore, they require special care and protection to ensure their health and safety.

[0119] Alarm control parameters can be control parameters for pre-set alarm rules. Since the alarm rules in this solution can include alarm levels and alarm strategies, if the pedestrian is a special concern, adjustments need to be made based on the determined alarm levels and alarm strategies. In this solution, when the pedestrian is elderly, since the elderly generally have hearing loss, it can be stipulated that the currently determined alarm level and alarm strategy be increased by one level. Correspondingly, the alarm control parameter can be set to +1. If the currently determined alarm level and alarm strategy are the highest level, then the current determined alarm level and alarm strategy are maintained. When the pedestrian is a child, since children are easily frightened, it can be stipulated that the currently determined alarm level and alarm strategy be decreased by one level. Correspondingly, the alarm control parameter can be set to -1. If the currently determined alarm level and alarm strategy are the lowest level, then the current determined alarm level and alarm strategy are maintained. If the current determined alarm level and alarm strategy are maintained, the alarm control parameter can be set to 0. When determining the setting strategy for alarm control parameters, this strategy can be pre-set in the smart terminal.

[0120] The target speaker's operating parameters can be the speaker playback volume determined by alarm control parameters. In this solution, since the pre-set alarm rules can include alarm levels and alarm strategies, the speaker playback volume can change according to the alarm level and alarm strategy. For each level increase in the alarm level and alarm strategy, the speaker playback volume increases by 25%. If the target speaker playback volume determined by the alarm level and alarm strategy is 50% of the maximum volume, and the alarm control parameter is -1, then the target speaker's operating parameter is 25%. When determining the adjustment strategy for the target speaker's operating parameters, this adjustment strategy can be preset within the speaker's chip.

[0121] In this solution, since vibration information can include gait, speed, frequency, direction and acceleration, after the sensor transmits the vibration information to the smart terminal through wireless communication technology, the smart terminal can use motion sensing technology to analyze the gait, speed, frequency, direction and acceleration of a person walking, and determine the height, age, gender and other information of the walker, thereby determining whether the pedestrian is a special concern type.

[0122] If the pedestrian is a special concern, the smart terminal will further determine whether the pedestrian is elderly or a child, and automatically invoke the pre-stored alarm control parameter setting strategy to determine the alarm control parameters. These parameters are then transmitted wirelessly to the target speaker's chip. Upon receiving the alarm control parameters, the target speaker chip automatically invokes the target speaker's operating parameter adjustment strategy to determine the speaker's operating parameters. Finally, the amplifier in the chip adjusts the playback volume to play the alarm information. There are generally three methods: circuit control, digital control, and analog control. Circuit control uses the amplifier's internal circuitry to control the amplifier's output volume; digital control uses digital signals to control the amplifier's output volume; and analog control uses the amplifier's analog input signals to control the amplifier's output volume.

[0123] This solution allows for the flexible playback of alarm information by setting specific attention types and correspondingly determining alarm control parameters and target speaker operating parameters. This ensures that people in the specific attention type can safely receive alarm information and relocate to a safe location based on the alarm notification. This avoids situations where people in the specific attention type fail to receive alarm information, leading to danger or being disturbed by alarm messages.

[0124] A loudspeaker can be an electronic device used to convert sound into electrical signals and then into audible sound.

[0125] Since underground cables may vary in length during installation, it is recommended to install two loudspeakers every 20 meters along the cable's installation direction. Specifically, one loudspeaker will be installed directly above the starting point of the cable installation, another at the 20-meter mark, and a third at the 40-meter mark, and so on. The last loudspeaker can be installed at the end point of the cable installation, thus ensuring that the loudspeakers are positioned opposite each other along the cable's installation direction.

[0126] The target speaker can be a speaker that plays alarm information.

[0127] When determining the speaker locations, all speaker positions can be pre-stored in a database table on the smart terminal. When the smart terminal generates an alarm, it searches the database for the speaker closest to the pedestrian's real-time location, as well as the speaker directly opposite it, to identify the target speakers. For example, if the underground cable is 60 meters long and the pedestrian's real-time location is 25 meters from the cable's starting point, and two speakers are to be placed every 20 meters along the cable's direction, then the target speakers are the speaker directly above the pedestrian at the 20-meter mark and the speaker directly above the pedestrian at the 40-meter mark. After identifying the target speakers, the smart terminal transmits the alarm information to the target speakers via wireless communication. Upon receiving the alarm information, the target speakers will play the alarm message in their opposite direction. Specifically, since there are different alarm levels and alarm policies in the pre-set alarm rules, when the alarm level and alarm policy are at the lowest level, the volume of the alarm information played by the speaker can be set to 25% of the maximum volume. For each increase in the alarm level and alarm policy, the volume of the alarm information played will increase by 25% accordingly. When the alarm level is at the highest level, the volume of the alarm information played will be the maximum volume.

[0128] In this embodiment, a vibration detection module is used to acquire vibration information when a pedestrian passes by through a sensor; a location identification module is used to determine the real-time location of the pedestrian based on the strength of the vibration information; a comparison module is used to compare the real-time location of the pedestrian with the cable burial location to determine whether they overlap or are within a preset range of the cable burial location; an identification module generates alarm information according to pre-set alarm rules when they overlap or are within the preset range; and an alarm module includes at least two speakers, which are positioned at two points directly above the cable burial location and facing each other in the direction of cable burial, to receive alarm information, identify target speakers, and play the alarm information through the target speakers. By comparing the real-time location of the pedestrian with the cable burial location to determine alarm information and using the opposing speakers to issue an alarm, the device can more accurately detect whether a pedestrian is approaching the cable burial location and issue an alarm in a timely manner, making it easier for pedestrians to hear the alarm and thus better protecting the safety of both pedestrians and the cable.

[0129] The hazard alarm device for underground buried cables in this application embodiment can be a device, or a component, integrated circuit, or chip in a terminal. The device can be a mobile electronic device or a non-mobile electronic device. For example, mobile electronic devices can be mobile phones, tablets, laptops, PDAs, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc., while non-mobile electronic devices can be servers, network attached storage (NAS), personal computers (PCs), televisions (TVs), ATMs, or self-service machines, etc. This application embodiment does not impose specific limitations.

[0131] Example 2

[0132] Figure 2 This is a schematic diagram of the structure of the hazard warning device for underground buried cables provided in Embodiment 2 of this application. Figure 2 As shown, it specifically includes the following:

[0133] The identification module 104 is further used for:

[0134] If the locations overlap or fall within a preset range, identify the burial depth and burial method of the cable burial location;

[0135] Determine whether the cable is a dangerous cable based on the burial depth and the burial method;

[0136] If so, an alarm message will be generated.

[0137] In this scheme, the burial depth can be the straight-line distance from the burial location of the underground cable to the ground.

[0138] The installation methods can include the following:

[0139] 1. Direct burial: Direct burial refers to an installation method in which the cable is buried directly underground, rather than using pipes or other methods for installation.

[0140] 2. Through-wall type: This type involves passing underground cables through walls from one place to another, used to connect cables.

[0141] 3. Conduit type: The underground cable is placed inside a conduit to enhance the cable's protection and durability.

[0142] 4. Trench type: The underground cable is placed in a trench to prevent the cable from being damaged.

[0143] 5. Conduit type: Underground cables are placed inside conduits to prevent them from getting damp and exposed to direct sunlight.

[0144] 6. Rope type: The underground cable is placed inside a rope to ensure the stability and durability of the cable.

[0145] Underground cable detectors can be used to identify the burial depth and method of cables. These detectors can detect the cable's location, depth, direction, and type. When a pedestrian's real-time location coincides with or is within a preset range of the cable's burial location, a smart terminal can transmit detection commands to the underground cable detector via wireless communication technology. After identifying the burial depth and method, the underground cable detector can transmit the data back to the smart terminal via wireless communication.

[0146] Hazardous cables refer to underground cables that pose a potential danger to pedestrians, specifically those that could cause electric shock, burns, or other injuries. The criteria for classifying underground cables as hazardous vary depending on the burial depth and method. For example, directly buried underground cables, lacking protective measures, are more likely to cause injury to pedestrians the shallower they are buried; therefore, a burial depth of 1 meter or more can be considered hazardous for such cables. As external protection measures for underground cables increase, the burial depth required for hazardous cables can also increase. For instance, a wall-penetrating underground cable buried at 1.5 meters or more, and a trench-grouted underground cable buried at 2 meters or more, can be classified as hazardous.

[0147] Once the criteria for determining the burial depth and method of dangerous cables are established, these criteria can be pre-stored in a database. When the smart terminal receives the burial location, depth, and method of the cable from the underground cable detector, it compares this information with the pre-stored criteria in the database. If the criteria are met, the cable is determined to be dangerous. Once a dangerous cable is identified, the smart terminal automatically invokes pre-set alarm rules to generate an alarm message.

[0148] In this embodiment, by identifying whether an underground cable is a dangerous cable based on its burial depth and burial method, the existence of dangerous cables can be accurately identified, and alarm information can be issued in a timely manner to prevent accidents and better protect the safety of pedestrians and cables.

[0149] Based on the above technical solutions, optionally, the identification module 104 is further used for:

[0150] Identify the burial environment information of the cable burial location, as well as the cable burial duration information;

[0151] Based on the buried environment information and the buried duration information, determine whether the cable is a dangerous cable;

[0152] If so, an alarm message will be generated.

[0153] In this plan, the environmental information for the cable burial location may include soil, bricks, slabs, or concrete support structures.

[0154] Cable burial time information can refer to the total time it takes to bury a cable underground at a specific location.

[0155] Ultrasonic testing equipment can be used to apply ultrasonic scanning technology to identify the burial environment information of cable installation locations. Ultrasonic testing equipment can accurately analyze information such as the shape, thickness, and depth of an object by emitting sound waves and detecting the sound waves reflected back from its surface, thereby determining the burial environment information of the cable installation location.

[0156] The burial duration of underground cables can be identified using underground cable body measurement technology, magnetic technology, radar technology, or visualization technology. Underground cable body measurement technology obtains burial duration information by measuring the cable's thickness, length, and weight; magnetic technology detects burial duration information by utilizing abnormal changes in the magnetic field; radar technology detects burial duration information by utilizing the reflection and refraction of radar signals within the cable; and visualization technology uses equipment such as cameras and laser rangefinders to detect burial duration information. In this solution, a laser rangefinder can be used to identify the burial duration information of the underground cables.

[0157] Whether a cable is considered hazardous can be determined based on the severity of corrosion from its underground burial environment and the length of time it has been buried. If the burial environment includes soil, bricks, slabs, and concrete structures, cables buried in soil experience the least corrosion because soil provides some protection against external factors. Next are cables buried in bricks and slabs, which offer some protection, but gaps still allow corrosion. Finally, cables buried in concrete suffer the most severe corrosion because concrete has larger gaps than bricks and slabs, allowing more external factors to corrode the cable. Correspondingly, the higher the degree of corrosion, the shorter the burial time required to reach hazardous cable standards; conversely, the lower the degree of corrosion, the longer the burial time. In this scheme, it can be set that when the burial environment is soil, a cable is considered dangerous after five years; when the burial environment is bricks and slabs, a cable is considered dangerous after four years; and when the burial environment is a concrete structure, a cable is considered dangerous after three years. After determining the criteria for judging a cable as dangerous, these criteria can be pre-stored in the database of the smart terminal.

[0158] Once an ultrasonic tester identifies the burial environment information of the cable's location and a laser rangefinder identifies the burial duration of the underground cable, both devices can transmit this information wirelessly to a smart terminal. Upon receiving this information, the smart terminal automatically queries its database to determine if the cable is a hazardous cable based on the burial environment and burial duration criteria. It then compares the received information with the database to confirm whether the cable is hazardous. If a cable is determined to be hazardous, the smart terminal automatically generates an alarm based on pre-set alarm rules.

[0159] In this solution, by determining whether a cable is a dangerous cable based on the information of the burial environment at the cable's location and the cable's burial duration, dangerous cables can be detected in a timely manner, and alarm information can be issued promptly so that pedestrians can stay away from dangerous cables, effectively preventing safety hazards caused by buried cables and reducing the probability of safety problems.
