Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0047] First of all, the usage scenario of this solution can be a scenario for detecting cable bulging, especially for detecting bulging on the outer surface of the cable insulation layer. By obtaining the current distance data of at least two preset positions on the cable to be monitored to filter out the abnormal distance position, determining the distance change trend of the abnormal distance position within a preset time period based on the historical distance data, and determining whether there is a bulging phenomenon at the abnormal distance position based on the distance change trend, the purpose of automatically detecting cable bulging without manual observation can be achieved, thereby improving the timeliness and accuracy of the cable bulging alarm. Based on the above usage scenarios, it can be understood that the executor of this solution can be an electronic device, such as: smart terminals such as mobile phones and computers, and no excessive restrictions are made here.
[0048] The cable bulge alarm system and method based on laser ranging provided in the embodiment of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0049] Figure 1 It is a flow chart of a cable bulge alarm method based on laser ranging provided in an embodiment of the present application.
[0050] like Figure 1 As shown, the specific steps include:
[0051] S101, obtaining distance measurement parameters reported by a laser sensor, and determining current distance data between the laser sensor and at least two preset positions on a cable to be monitored according to the distance measurement parameters.
[0052] Among them, the laser sensor can be a device that uses laser technology to measure distance. The laser sensor is composed of a laser, a laser detector and a measuring circuit. The distance measurement parameter can be a distance parameter between the location of the laser sensor and each preset location. The distance measurement parameter can be obtained by the laser sensor transmitting and receiving laser measurements. The preset position can be a point or area to be monitored for bulging that is pre-set by the user on the cable to be monitored. There are at least two preset positions on the cable to be monitored, and at least two of them can be set at equal or unequal intervals, and the bulging conditions of at least two preset positions can reflect the bulging conditions of the insulation layer of the entire cable to be monitored. The current distance data can be the distance parameter between the laser sensor and each preset position at the current moment.
[0053] In one embodiment, the ranging parameters reported by the laser sensor can be obtained through an interface that interacts with the laser sensor, and the current distance data between the laser sensor and at least two preset positions on the cable to be monitored can be determined based on the distance parameters corresponding to each preset position in the ranging parameters.
[0054] S102, screening out abnormal distance positions among at least two preset positions according to current distance data, and reading pre-stored historical distance data of the abnormal distance positions.
[0055] The abnormal distance position may be a preset position where the distance parameter of the laser sensor is abnormal. The historical distance data may be the distance parameter between the laser sensor and the same abnormal distance position reported by the laser sensor before the current moment. The historical distance data may include distance parameters reported at multiple distance reporting moments.
[0056] In one embodiment, the changing trend of the current distance data with the preset position can be determined according to the arrangement order of at least two preset positions on the cable to be monitored, and the preset position corresponding to the current distance data that does not conform to the changing trend is determined as the distance abnormal position. For example: the laser sensor is set at the leftmost side of the cable to be monitored, and the arrangement order of at least two preset positions on the cable to be monitored is a straight line arrangement from left to right, then the changing trend of the current distance data with the preset position is monotonically increasing. At this time, if the current distance data of one or more preset positions does not conform to the monotonically increasing trend, the position is determined as the distance abnormal position. It is also possible to pre-enter the standard distance data at each preset position when the cable to be monitored does not have a bulge phenomenon, compare the difference between the current distance data at each preset position and the standard distance data to see if it conforms to the preset distance floating range, and determine the preset position whose difference exceeds the preset distance floating range as the distance abnormal position. The preset distance floating range can be the maximum and minimum values of multiple standard distance data at the same preset position. The historical distance data of the distance abnormal position in the pre-stored historical distance data can be read according to the position identifier of the distance abnormal position.
[0057] In one embodiment, optionally, screening the abnormal distance positions in at least two preset positions according to the current distance data includes:
[0058] Calculate the difference between the current distance data of two adjacent preset positions respectively, and determine the distance change law between the laser sensor and each preset position according to the difference between the current distance data;
[0059] The jump difference in the difference of the current distance data is determined according to the distance variation rule, and the preset position associated with the jump difference is used as the distance abnormality position.
[0060] The distance variation rule may be a variation characteristic of the distance data between the laser sensor and each preset position. For example, the distance may vary according to a fixed distance difference or according to a monotonically increasing trend. A jump difference may be a difference that does not conform to the distance variation rule. The preset positions associated with the jump difference may be two adjacent preset positions corresponding to two current distance data used to calculate the difference.
[0061] In one embodiment, the difference between the current distance data of two adjacent preset positions can be calculated based on the current distance data of each preset position, and the distance change law between the laser sensor and each preset position can be determined based on the difference between the current distance data. For example, if the difference between the current distance data is a fixed value, it can be determined that the distance between the laser sensor and each preset position increases according to a fixed value. Since there may be one or more preset positions of bulges in at least two preset positions, the distance change law that meets most of the difference characteristics can be determined based on the difference between the current distance data, and the difference between the current distance data that does not meet the distance change law is determined as a jump difference, and the preset position associated with the jump difference is used as the distance abnormality position.
[0062] This solution determines the distance change pattern between the laser sensor and each preset position by respectively calculating the difference between the current distance data of two adjacent preset positions, and uses the preset position associated with the jump difference as the distance abnormal position, which can improve the efficiency of screening the distance abnormal position.
[0063] S103, determining a distance variation trend of the abnormal distance position within a preset time period according to historical distance data, and determining whether there is a bulge phenomenon at the abnormal distance position according to the distance variation trend.
[0064] The distance change trend may be the change characteristics of the distance data at the same distance abnormal position within a preset time period. The bulging phenomenon may be a phenomenon in which the insulation layer of the monitored cable is bulged. If there is a bulging phenomenon at the distance abnormal position of the monitored cable, the actual distance data at the position is less than the standard distance data, and the change trend of the historical distance data at the position during the bulging process may be continuously reduced.
[0065] In one embodiment, the distance change trend of the distance abnormal position within a preset time period can be determined based on the change of the historical distance data of the same distance abnormal position. For example: the difference of the historical distance data of two adjacent time points is calculated according to the reporting time of the historical distance data, and the distance change trend of the distance abnormal position in each time period within the preset time period is determined based on the difference. Determine whether there is a bulge phenomenon at the distance abnormal position based on the distance change trend. For example: determine whether there is a bulge on the outer surface of the insulation layer of the monitored cable based on whether the distance change trend of the historical distance data of the same distance abnormal position is an overall decreasing trend. If it is an overall decreasing trend, it is determined that there is a bulge at the distance abnormal position, i.e., a bulge phenomenon.
[0066] S104, when there is a bulge phenomenon at the abnormal distance position, a bulge alarm of the cable to be monitored is issued.
[0067] Among them, the bulge alarm can be information used to inform cable maintenance personnel that the cable to be monitored has bulge phenomenon.
[0068] In one embodiment, when a bulge phenomenon exists at a distance from an abnormal position, a bulge alarm of the cable to be monitored is sent to a cable maintenance client of the cable to be monitored.
[0069] The technical solution provided by the embodiment of the present application obtains the ranging parameters reported by the laser sensor, determines the current distance data between the laser sensor and at least two preset positions on the cable to be monitored according to the ranging parameters; screens the abnormal distance position in at least two preset positions according to the current distance data, and reads the historical distance data of the abnormal distance position stored in advance; determines the distance change trend of the abnormal distance position within a preset time period according to the historical distance data, and determines whether there is a bulge phenomenon at the abnormal distance position according to the distance change trend; in the case of a bulge phenomenon at the abnormal distance position, issues a bulge alarm for the cable to be monitored. The above-mentioned cable bulge alarm method based on laser ranging solves the problems of untimely cable bulge alarm and inaccurate bulge phenomenon judgment in the prior art. By obtaining the current distance data of at least two preset positions on the cable to be monitored to screen the abnormal distance position, determining the distance change trend of the abnormal distance position within a preset time period according to the historical distance data, and determining whether there is a bulge phenomenon at the abnormal distance position according to the distance change trend, the purpose of automatically detecting the cable bulge phenomenon without manual observation can be achieved, thereby improving the timeliness and accuracy of the cable bulge alarm.
[0070] Figure 2 Flowchart for determining cable bulging phenomenon provided by the embodiment of the present application. Figure 2 As shown, the specific steps include:
[0071] S201, identifying whether the distance change trend is a decreasing trend, where the distance change trend is a change trend of historical distance data of the same distance abnormal position within a preset time period.
[0072] Among them, the decreasing trend can be the trend that the historical distance data of the distance abnormal location decreases with the distance data reporting time. The decreasing trend can be the trend that the distance data decreases according to a fixed value or an unfixed value. The distance change trend can be the change characteristics of the historical distance data of the same distance abnormal location within a preset time period.
[0073] In one embodiment, whether the distance change trend of the distance abnormal position is a decreasing trend may be determined based on whether the change trend of the historical distance data of the same distance abnormal position within a preset time period is continuously decreasing.
[0074] In one embodiment, optionally, after identifying whether the distance change trend is a decreasing trend, the method further includes:
[0075] If the distance change trend is a trend of decreasing first and then increasing, calculate whether the increasing amount reaches the decreasing amount;
[0076] When the increment does not reach the decrement, it is determined that a bulge exists at the abnormal distance position.
[0077] Among them, the increment can be the total increment of the distance data of the abnormal position within the preset time length. The increment can be determined according to the difference between the maximum value of the historical distance data of the abnormal position within the preset time length and the standard distance data. The standard distance data can be the distance parameter between the abnormal position and the laser sensor when the cable to be monitored does not have a bulge phenomenon. The standard distance data can be predicted based on the change characteristics of the distance data between the laser sensor and each preset position. The decrement can be the total decrement of the distance data of the abnormal position within the preset time length. The decrement can be determined according to the difference between the minimum value of the historical distance data of the abnormal position within the preset time length and the standard distance data.
[0078] In one embodiment, if the distance change trend is a trend of decreasing first and then increasing, the increment and decrement of the distance change trend within the preset time length can be calculated based on the difference between the maximum value, the minimum value of the historical distance data and the standard distance data of the distance abnormal position within the preset time length. It is determined whether the increment reaches the decrement by calculating whether the difference between the increment and the decrement is greater than 0. In the case where the difference between the increment and the decrement is less than 0, that is, the increment does not reach the decrement, it can be determined that there is a situation where the distance abnormal position first bulges and then retracts, but the degree of bulging is greater than the degree of retraction, so there is a bulging phenomenon at the distance abnormal position.
[0079] This scheme calculates whether the incremental amount reaches the decreasing amount when the distance change trend of the abnormal distance position is a trend of first decreasing and then increasing. If the incremental amount does not reach the decreasing amount, it is determined that there is a bulging phenomenon at the abnormal distance position. It can further determine whether there is a bulging phenomenon in the cable to be monitored, thereby improving the accuracy of judging the cable bulging phenomenon.
[0080] In one embodiment, optionally, when the increment does not reach the decrement, determining that there is a bulge at the abnormal distance position includes:
[0081] In the case where the increment does not reach the decrement, a hardness measurement instruction of the abnormal position is issued to the maintenance client of the cable to be monitored;
[0082] Receive the hardness parameter reported by the maintenance client and identify whether the hardness parameter reaches the cable bulge hardness threshold;
[0083] When the hardness parameter reaches the cable bulge hardness threshold, it is determined that there is a bulge at the abnormal distance position.
[0084] Among them, the hardness measurement instruction can be an operation command for informing the maintenance client of the cable to be monitored to perform hardness measurement on the abnormal distance position of the cable to be monitored. The hardness measurement instruction may include the identification of the cable to be monitored and the position number of the abnormal distance position. The hardness parameter can be the hardness data of the abnormal distance position of the cable to be monitored. The cable bulging hardness threshold can be the minimum hardness value when the bulging phenomenon occurs in the cable to be monitored.
[0085] In one embodiment, when the increment does not reach the decrement, it means that there is no obvious protrusion on the outer surface of the insulation layer of the monitored cable. At this time, a hardness measurement instruction for the abnormal distance position can be issued to the maintenance client of the monitored cable. The hardness parameter reported by the maintenance client is received, and the hardness parameter is compared with the pre-stored cable bulge hardness threshold to determine whether the hardness parameter reaches the cable bulge hardness threshold. When the hardness parameter reaches the cable bulge hardness threshold, it can be determined that there is a bulge phenomenon at the abnormal distance position.
[0086] This solution sends a hardness measurement instruction of the abnormal distance position to the maintenance client of the cable to be monitored when the incremental amount of the distance change trend of the abnormal distance position has not reached the decreasing amount. When the hardness parameter reaches the cable bulge hardness threshold, it is determined that there is a bulge phenomenon at the abnormal distance position. The purpose of detecting the cable bulge phenomenon when there is no obvious change in the appearance of the cable to be monitored can be achieved, and the accuracy of cable bulge phenomenon detection is further improved.
[0087] S202: If the distance variation trend is a monotonically decreasing trend, it is determined that a bulge exists at the abnormal distance position.
[0088] In one embodiment, if the distance change trend is a monotonically decreasing trend, it means that the outer surface of the insulation layer of the monitored cable at the abnormal distance position has been in a convex upward trend within a preset time period. At this time, it can be determined that there is a bulging phenomenon at the abnormal distance position.
[0089] The technical solution provided in the embodiment of the present application can simplify the steps of detecting the cable bulging phenomenon and improve the detection efficiency of the cable bulging phenomenon by identifying that the distance change trend is a decreasing trend and determining that a bulging phenomenon exists at the abnormal distance position.
[0090] Figure 3 This is a flowchart of issuing a bulge warning provided by an embodiment of the present application. Figure 3 As shown, the specific steps include:
[0091] S301, when there is a bulge phenomenon at the distance abnormality position, determine the bulge parameter of the distance abnormality position according to historical distance data.
[0092] The bulge parameter may be a value that can represent the size of the bulge relative to the abnormal position.
[0093] In one embodiment, when there is a bulge at the distance abnormality position, the distance average of the historical distance data at the position can be calculated based on the historical distance data of the distance abnormality position, and the difference between the distance average and the minimum value of the historical distance data is determined as the bulge parameter of the distance abnormality position.
[0094] In one embodiment, optionally, determining the bulge parameter of the distance abnormality position according to the historical distance data includes:
[0095] Identify the maximum distance value and the minimum distance value in the historical distance data and the current distance data;
[0096] The difference between the maximum distance value and the minimum distance value is calculated, and the difference between the maximum distance value and the minimum distance value is used as the bulge parameter of the distance abnormality position.
[0097] In one embodiment, the sizes of all data in the historical distance data and the current distance data can be compared to determine the maximum distance value and the minimum distance value, and the maximum distance value is subtracted from the minimum distance value to obtain the difference, and the difference between the maximum distance value and the minimum distance value is used as the bulge parameter of the distance abnormality position.
[0098] This solution determines the bulge parameter of the distance abnormality position by calculating the difference between the maximum distance value and the minimum distance value in the historical distance data and the current distance data, which can improve the calculation efficiency of the bulge parameter.
[0099] S302: Determine the bulge level at the distance to the abnormal position according to the bulge parameter and the association relationship between the preset bulge parameter and the bulge level.
[0100] The association between the preset bulge parameter and the bulge level may be a preset correspondence between the bulge level of the cable to be monitored and the range of the bulge parameter. The bulge level may be data used to indicate the severity of the bulge of the cable to be monitored.
[0101] In one embodiment, the bulge level corresponding to the bulge parameter at the distance from the abnormal position may be determined according to the bulge parameter and the association relationship between the preset bulge parameter and the bulge level.
[0102] S303, identifying the position number of the abnormal position, writing the bulge level into the alarm level field of the position number in the bulge alarm, and issuing a bulge alarm for the cable to be monitored.
[0103] The position number may be a sequence number of at least two preset positions in the distance from the abnormal position. At least two preset positions on the cable to be monitored may be numbered in advance in order from left to right to obtain the position number of each preset position, and the position number is associated with the preset position.
[0104] In one embodiment, the position number of the distance to the abnormal position is identified, the bulge level is written into the alarm level field of the position number of the distance to the abnormal position in the bulge alarm, and a bulge alarm of the cable to be monitored is issued.
[0105] The technical solution provided in the embodiment of the present application determines the bulge parameters of the abnormal distance position based on historical distance data, determines the bulge level of the abnormal distance position based on the bulge parameters and the correlation between the preset bulge parameters and the bulge level, writes the bulge level into the alarm level field of the position number in the bulge alarm, and issues a bulge alarm for the cable to be monitored. This can serve the purpose of warning of the severity of the bulge and improve the comprehensiveness of the cable bulge alarm.
