[0002] The grounding box can provide a reliable grounding connection for the cable, and safely conduct the fault current and electrostatic charge in the cable to the earth. At the same time, a variety of sensors can be set in the grounding box to monitor the operating status of the cable.

[0003] However, in the long-term operation of the sensors in the grounding box, not only will they face external damage, water immersion, corrosion and other problems, but they will also have the risk of aging, which will cause the sensors themselves to be unable to collect accurate monitoring data. The monitoring system will misidentify or fail to effectively identify cable operation abnormalities based on erroneous monitoring data, which will have a great impact on cable maintenance. If staff are arranged to inspect the sensors, the technical effect of the sensors in monitoring the cable operation status will be greatly reduced.

[0049] The following, in conjunction with the accompanying drawings, describes in detail the self-test device, method and equipment of the cable grounding box sensor provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0050] Embodiment 1

[0051] Figure 1 Schematic diagram of the structure of the self-test device of the cable grounding box sensor provided in the first embodiment of the present application. Figure 1 As shown, the specific steps include:

[0052] The target grounding box determination module 101 is used to obtain a grounding box identification number and determine a target grounding box to be self-checked according to the grounding box identification number;

[0053] A target sensor determination module 102 is used to determine a sensor inside the target grounding box as a target sensor; wherein the target sensor includes one or more of a temperature sensor, a humidity sensor, and a current sensor;

[0054] A self-check instruction sending module 103, used to send a self-check instruction to the target sensor, turn off the target sensor, and turn on the target sensor after a preset time;

[0055] The self-test result determination module 104 is used to continuously receive the collected data of the target sensor, and if the collected data matches the self-test instruction, determine that the target sensor passes the self-test.

[0056] The application scenario of this solution may be a scenario of self-checking the sensor in the cable grounding box.

[0057] Based on the above scenario, it can be understood that the executor of this scenario can be a detection terminal that identifies whether there is an abnormality in the target sensor, such as a desktop computer, a laptop computer, a tablet computer, and an interactive multimedia device, etc., and no excessive limitations are made here.

[0058] The target grounding box determination module 101 may be a program design of the detection terminal for determining the target grounding box where the sensor that needs to be self-tested is located. Specifically, the grounding box may be an electrical device that provides a reliable grounding connection for the cable, safely directs the fault current and electrostatic charge in the cable into the earth, and prevents electrical accidents. The grounding box can prevent the cable from being damaged by external factors such as lightning strikes and overvoltage, reduce the aging and damage of the cable insulation layer, extend the service life of the cable, and improve the reliability of the cable. The grounding box can also provide an installation location for the sensor used to detect the operating status of the cable, and at the same time can protect the sensor from damage by external factors to a certain extent.

[0059] The grounding box identification number may be a number used to determine the identity information of the grounding box. The grounding box identification number may be set when the grounding box leaves the factory, or may be set according to the use needs when the grounding box is installed. Each grounding box corresponds to a unique identification number. After the grounding box is installed, the identification number is associated with the installation location, connection cable and other information and stored, so that the grounding box can be quickly retrieved.

[0060] The target grounding box may be a grounding box in which a sensor that needs to be self-checked is installed, and the sensor disposed inside the target grounding box may be determined through the associated information of the target grounding box.

[0061] Self-checking can be a detection method that determines whether the sensor has communication interruption or measurement error by analyzing the collected data reported by the sensor.

[0062] The method for determining the target grounding box to be self-inspected is that the staff inputs the identification number of the grounding box to be self-inspected into the detection terminal. After the detection terminal receives it, the identification number is searched in the database storing the relevant information of the grounding box, and the searched grounding box is used as the target grounding box.

[0063] The target sensor determination module 102 may be a program design of the detection terminal for determining the target sensor. Specifically, the target sensor may be a sensor that needs to be self-checked. In this solution, each sensor may be checked regularly according to the self-check cycle, or the staff may specify the current target sensor separately according to the use needs.

[0064] The temperature sensor can be installed in the grounding box to collect temperature data of the cable operating environment. The temperature sensor can sense the temperature of the environment and convert it into an electrical signal for output by using the property that the resistance value of the metal conductor changes with the temperature.

[0065] The humidity sensor can be set in the grounding box to collect humidity data of the cable operating environment. The humidity sensor can use the property that the dielectric constant of the humidity-sensitive material changes with the relative humidity. When the ambient humidity changes, the capacitance value of the humidity-sensitive material changes, thereby changing the electrical signal in the circuit. By measuring the change of the electrical signal, the change data of the ambient humidity can be obtained.

[0066] The current sensor can be set in the grounding box to collect the current value of the cable during operation. Based on the law of electromagnetic induction, when the measured current passes through the Rogowski coil inside the current sensor, an induced electromotive force will be generated in the coil. The magnitude of the induced electromotive force is measured by the circuit inside the current sensor to determine the current magnitude of the measured cable.

[0067] The target sensor can be determined by obtaining the associated information of the target grounding box, obtaining all sensors set inside the target grounding box from the associated information, using the obtained sensor as the target sensor, extracting the communication address of the target sensor, and establishing a data transmission channel with the target sensor.

[0068] The self-check instruction sending module 103 may be a program design for the detection terminal to send a self-check instruction to control the target sensor to start the self-check task. Specifically, the self-check instruction may be a program instruction for starting the self-check task of the target sensor. The self-check instruction includes information such as the closing instruction, the opening instruction, and the execution time node of the target sensor, and may convey the execution process of the self-check task to the target sensor.

[0069] The preset duration may be a shutdown duration of a target sensor used to distinguish whether the self-test program is turned on or off. The preset duration may be determined according to a data collection cycle of the target sensor.

[0070] The method of sending a self-test instruction to the target sensor can be to obtain the communication address of the target sensor after determining the target sensor, and send the pre-edited self-test instruction to each communication address. After receiving the self-test instruction, the target sensor runs the self-test instruction and performs operations such as closing, opening, and collecting data at the corresponding time nodes according to the instruction content. In this scheme, since the target sensor itself is provided with an acquisition cycle, in order to distinguish the data of the self-test task from the data of the target sensor's own acquisition task, the target sensor needs to be turned off, and the start of the self-test task is confirmed by the shutdown time. After the preset time, the target sensor is turned on again, and the target sensor is made to report the collected data according to the data collection time node in the self-test instruction. The data obtained at this time is the data required for the self-test task.

[0071] The self-test result determination module 104 may be a program design of the detection terminal for determining the self-test result according to the collected data. Specifically, the collected data may be data information acquired by the target sensor when performing its own collection task. For example, the ambient temperature data collected by the temperature sensor, the cable current value collected by the current sensor, etc.

[0072] The method of determining whether the target sensor has passed the self-test may be that after the detection terminal sends a self-test instruction to the target sensor, the feedback information of the target sensor is continuously received. At the same time, the target sensor executes the self-test instruction, generates feedback information based on the data collected according to the requirements of the self-test instruction, and sends it to the detection terminal. After receiving the feedback information, the detection terminal analyzes the collected data therein, obtains the time node of each collected data, matches the time node with the time node required in the self-test instruction, and if the match is consistent, it is determined that the current target sensor has passed the self-test.

[0073] Based on the above solution, optionally, the target grounding box determination module is specifically used to:

[0074] Receiving a grounding box identification number input by a user, and obtaining a communication address of the grounding box according to the identification number;

[0075] The communication verification is performed on the grounding box according to the communication address, and if the verification is successful, the current grounding box is used as the target grounding box.

[0076] The communication address can be information used to identify the location of a device or node in a network. Each grounding box has a unique communication address, and data can be transmitted to a specified grounding box according to the communication address.

[0077] The method for communication verification of the grounding box can be to search the communication address of the grounding box in the database according to the grounding box identification number, and send communication verification information to the communication address. If feedback information from the grounding box can be received, it is determined that communication can be established with the current grounding box. The communication verification is successful and the current grounding box is used as the target grounding box.

[0078] In this solution, a program code is provided for reference to determine whether the target sensor has passed the self-test:

[0079]

[0080]

[0081] In an embodiment of the present application, a target grounding box determination module is used to obtain a grounding box identification number, and determine the target grounding box to be self-checked according to the grounding box identification number; a target sensor determination module is used to determine the sensor inside the target grounding box as the target sensor; wherein the target sensor includes one or more of a temperature sensor, a humidity sensor, and a current sensor; a self-check instruction sending module is used to send a self-check instruction to the target sensor, turn off the target sensor, and turn on the target sensor after a preset time; a self-check result determination module is used to continuously receive the collected data of the target sensor, and if the collected data matches the self-check instruction, it is determined that the target sensor has passed the self-check. Through the self-check device of the above-mentioned cable grounding box sensor, the target sensor can be self-checked through the collected data, and the abnormality of the sensor in the grounding box can be discovered in time, thereby avoiding problems such as frequent alarms or delayed alarms caused by errors in the sensor reporting data, which is conducive to ensuring the accuracy of the cable operation monitoring system.

[0082] Embodiment 2

[0083] Figure 2 It is a structural diagram of the self-test device of the cable grounding box sensor provided in the second embodiment of the present application. This solution makes a better improvement on the above embodiment, and the specific improvement is: the self-test result determination module is also used to: continuously receive the acquisition data of the target sensor, determine the acquisition time node of the initial data after turning on the target sensor according to the acquisition data; compare the acquisition time node with the specified time node in the self-test instruction, and if they are consistent, it is determined that the target sensor has passed the self-test.

[0084] like Figure 2 As shown, specifically including the following:

[0085] The target grounding box determination module 201 is used to obtain a grounding box identification number and determine a target grounding box to be self-checked according to the grounding box identification number;

[0086] A target sensor determination module 202 is used to determine a sensor inside the target grounding box as a target sensor; wherein the target sensor includes one or more of a temperature sensor, a humidity sensor, and a current sensor;

[0087] A self-check instruction sending module 203, used to send a self-check instruction to the target sensor, turn off the target sensor, and turn on the target sensor after a preset time;

[0088] The self-test result determination module 204 is used to continuously receive the collected data of the target sensor, and if the collected data matches the self-test instruction, determine that the target sensor passes the self-test.

[0089] The self-test result determination module 204 is further configured to continuously receive the collected data of the target sensor, and determine the collection time node of the initial data after the target sensor is turned on according to the collected data;

[0090] The acquisition time node is compared with the specified time node in the self-test instruction. If they are consistent, it is determined that the target sensor has passed the self-test.

[0091] The collection time node of the initial data may be the time node of the first data collection after the target sensor is turned on, among the collected data fed back by the target sensor.

[0092] The specified time node may be a time node for collecting data for the first time after the target sensor is restarted as required in the self-test instruction, for example, collecting data starts at the second second after the target sensor is turned on.

[0093] The method of determining whether the target sensor has passed the self-test may be to obtain the specified time node in the self-test instruction and the time node of turning on the target sensor, calculate the standard collection time node of the initial data after turning on the target sensor according to the sum of the specified time node and the time node of turning on the target sensor, and compare the collection time node of the initial data actually recorded in the collected data with the standard collection time node. If they are consistent, it is determined that the target sensor has passed the self-test. For example, if the time node of turning on the target sensor is 12:03:22, the collection time node of the initial data in the collected data is 12:03:26, and the specified time node is to start collecting data at the 2nd second after turning on the target sensor, it can be calculated that the standard collection time node should be 12:03:24. If the collection time node in the collected data is inconsistent with the standard collection time node, then the target sensor has not passed the self-test.

[0094] The advantage of this setting of the scheme is that it can verify whether the target sensor can correctly receive and process instructions and whether the clock inside the target sensor is accurate by comparing the acquisition time node with the specified time node, which is conducive to detecting the function of the target sensor and discovering abnormal problems in time to avoid affecting the accuracy of cable monitoring.

[0095] Embodiment 3

[0096] Figure 3 It is a structural schematic diagram of the self-test device of the cable grounding box sensor provided in Example 3 of the present application. This solution makes a better improvement on the above-mentioned embodiment, and the specific improvement is: the self-test result determination module is specifically used to: identify the time mark of the collected data, calculate the time interval between the first collected data collected before turning off the target sensor and the second collected data collected after turning on the target sensor; compare the time interval with the preset duration, and if the comparison is consistent, it is determined that the target sensor has passed the self-test.

[0097] like Figure 3 As shown, specifically including the following:

[0098] The target grounding box determination module 301 is used to obtain a grounding box identification number and determine a target grounding box to be self-checked according to the grounding box identification number;

[0099] A target sensor determination module 302 is used to determine a sensor inside the target grounding box as a target sensor; wherein the target sensor includes one or more of a temperature sensor, a humidity sensor, and a current sensor;

[0100] A self-check instruction sending module 303, used to send a self-check instruction to the target sensor, turn off the target sensor, and turn on the target sensor after a preset time;

[0101] The self-test result determination module 304 is used to continuously receive the collected data of the target sensor, and if the collected data matches the self-test instruction, determine that the target sensor passes the self-test.

[0102] The self-test result determination module 304 is specifically used to identify the time mark of the collected data, and calculate the time interval between the first collected data collected before turning off the target sensor and the second collected data collected after turning on the target sensor;

[0103] The time interval is compared with the preset time length, and if the comparison is consistent, it is determined that the target sensor has passed the self-test.

[0104] The time stamp can be the time node recorded when the target sensor performs each operation such as closing, opening, and data collection.

[0105] The first collected data may be data collected by the target sensor according to its own monitoring task before executing the task of shutting down the target sensor in the self-check instruction.

[0106] The second collected data may be data collected by the target sensor according to the collection requirements in the self-test instruction after the task of starting the target sensor in the self-test instruction is executed.

[0107] The method for calculating the time interval may be to identify the time identifier of the collected data, extract the last collection time of the first collected data and the initial collection time of the second collected data, and calculate the difference between the initial collection time and the last collection time as the time interval between the first collected data and the second collected data.

[0108] The method for determining whether the target sensor has passed the self-test is to obtain a preset time length in the self-test instruction, compare the time interval with the preset time length, and if the comparison is consistent, determine that the target sensor has passed the self-test; if the comparison is consistent, determine that the target sensor has not passed the self-test.

[0109] The benefit of this arrangement of the present invention is that it is possible to determine whether the target sensor has passed the self-test through the time interval and the preset duration, thereby providing a judgment standard for abnormal detection of the target sensor and helping to improve the accuracy of the self-test results.

[0110] Based on the above solution, optionally, the self-test result determination module is further used to:

[0111] Obtaining a parameter range of the target sensor;

[0112] Identify whether there is an abnormal value exceeding the parameter range in the second collected data, and if not, determine that the target sensor passes the self-test.

[0113] The parameter range of the target sensor can be the range of reasonable data that may appear according to the actual use of the target sensor. For example, the temperature sensor monitors the temperature data of the cable operating environment. According to the temperature change law of the area where the sensor is set, the parameter range of the temperature sensor is -20℃~40℃. If the temperature data collected by the temperature sensor is 80℃ or -100℃, which is not in line with the laws of nature, it can be determined that the temperature sensor is abnormal and the collected data is incorrect.

[0114] To obtain the parameter range of the target sensor, the temperature and humidity change patterns of the area where the target grounding box is located can be obtained through big data, and the minimum and maximum data in the temperature and humidity change patterns can be determined respectively, thereby determining the parameter range of the temperature sensor and the humidity sensor. To obtain the power consumption parameters of the cable connected to the target grounding box, the range of current values ​​when the cable is operating normally and when there is an abnormality can be obtained, and the parameter range of the current sensor can be determined based on the range of the current values.

[0115] A method for determining whether the target sensor has passed the self-test may be to obtain all values ​​in the second collected data, and compare the values ​​with the parameter range of the corresponding target sensor. If the value is not within the parameter range, it is determined to be an abnormal value. If there is no abnormal value in the second collected data, it can be determined that the target sensor has passed the self-test.

[0116] The advantage of this setting of the scheme is that it can detect whether the target sensor has an abnormal problem of inaccurate data collection by comparing the collected data with the parameter range, which is conducive to multi-directional detection of the operation of various functions of the target sensor and timely discovery of abnormal problems of the target sensor.

[0117] Based on the above solution, optionally, the self-test result determination module is further used to:

[0118] Pre-acquire multiple groups of second collected data of sensors in the grounding box whose operating states are known to be abnormal, use the second collected data as input variables and the operating states as labels to perform supervised training to build an abnormality analysis model;

[0119] The second collected data of the target sensor is input into a pre-built abnormality analysis model, and whether the target sensor passes the self-test is determined according to an output result of the abnormality analysis model.

[0120] The abnormality analysis model may be a learning model that can determine whether there is an abnormality in the target sensor through the second collected data.

[0121] The method of constructing the abnormality analysis model may be to pre-acquire multiple groups of second collected data of sensors in the grounding box whose operating status is known to be abnormal, and divide the second collected data into two categories: abnormal data and normal data according to whether the operating status is abnormal. The second collected data is used as an input variable and the operating status is used as a label to perform supervised training, learn the characteristics of the abnormal data and the normal data respectively, and then determine the classification algorithm of the second collected data, and then generate the abnormality analysis model.

[0122] A method for determining whether the target sensor has passed the self-test may be to input the second collected data of the target sensor currently acquired into a pre-built abnormality analysis model, and the abnormality analysis model determines whether the current second collected data is abnormal data or normal data based on a classification algorithm of the second collected data learned in advance. If the output result of the abnormality analysis model is abnormal data, the target sensor has not passed the self-test; if the output result of the abnormality analysis model is normal data, the target sensor has passed the self-test.

[0123] The benefit of this arrangement of the scheme is that it is possible to determine whether the target sensor has passed the self-test through the abnormal analysis model, which is conducive to establishing a more accurate and effective abnormality judgment algorithm and making the self-test result more accurate.

[0124] Based on the above solution, optionally, the self-test result determination module is specifically used to:

[0125] Obtaining a sampling period of the target sensor;

[0126] When the time interval is greater than the preset duration, it is calculated whether the time interval is less than the sum of the preset duration and twice the sampling period. If so, it is determined that the target sensor has passed the self-test.

[0127] The sampling period can be the time interval for collecting data required by the target sensor itself in the cable monitoring task. For example, in the process of cable monitoring, temperature data is collected every 6 hours.

[0128] The sampling period of the target sensor may be obtained by the detection terminal querying the monitoring task of the target sensor and extracting the sampling period of the target sensor therefrom.

[0129] The method for determining whether the target sensor has passed the self-test may be to calculate the time interval between the first collected data and the second collected data, and compare the time interval with the preset duration. If the time interval value is greater than the preset duration, the sum of the preset duration and twice the sampling period is calculated, and the calculation result is compared with the time interval. If the time interval is less than the calculation result, it is determined that the target sensor has passed the self-test. For example, if the time interval is 18 seconds, the preset duration is 10 seconds, and the sampling period is 5 seconds, the sum of the preset duration and twice the sampling period is 20 seconds. At this time, the time interval is greater than the preset duration and less than the sum of the preset duration and twice the sampling period, and the target sensor has passed the self-test.

[0130] The advantage of this arrangement of the present scheme is that it can take into account the influence of the sampling period of the target sensor on the time interval, which is helpful to avoid the situation where the sampling period extends the time interval and causes misjudgment of the self-test result, thereby improving the accuracy of the self-test result.
