[0001] The present application relates to the field of power equipment sensors, and in particular to a dynamic monitoring method and system for power equipment sensors. Background Art

[0002] In the field of power equipment, especially in power station scenarios, multiple sensors are required to detect the working status of power equipment. For example, partial discharge sensors are used to test the partial discharge parameters of power equipment.

[0003] In a project of newly built power equipment, GIS partial discharge sensors are installed supporting the power equipment to form a GIS partial discharge on-line monitoring device. The tasks of the GIS partial discharge on-line monitoring device for monitoring and diagnosis are to understand and master the operating status of power equipment, including adopting various detection, measurement, monitoring, analysis and discrimination methods to evaluate the operating status of the equipment. Judge whether it is in a normal or abnormal state, display and record the status, give an alarm for the abnormal state, so that the operating personnel can handle it in time, and provide information and prepare basic data for the fault analysis, performance evaluation, reasonable use and safe operation of the equipment. Realize the condition-based maintenance of switch insulation, reduce the power outage time and save the management and maintenance costs.

[0004] When the project of power equipment operates normally, the corresponding power equipment sensors will also detect normally. In addition to the power equipment sensors detecting the power equipment, the corresponding maintenance department will also conduct patrol monitoring on the power equipment. For the power equipment sensors, a method is also needed to monitor the operating status of the power equipment sensors. Summary of the Invention

[0005] In order to be able to conduct patrol inspections to master the working status of power equipment sensors, the present application provides a dynamic monitoring method and system for power equipment sensors.

[0006] In the first aspect, the present application provides a dynamic monitoring method for power equipment sensors, adopting the following technical solution:

[0007] A dynamic monitoring method for power equipment sensors includes the following steps:

[0008] Obtain the position coordinates of all power equipment sensors, calculate the traversal route passing through all the position coordinates, wherein two of the power equipment sensors are set to be data-connected after being adjacent within a preset distance range;

[0009] Conduct a patrol inspection according to the traversal route, and obtain the joining coordinates of newly added power equipment sensors;

[0010] If the joining coordinates are obtained, calculate an updated route according to the joining coordinates and the remaining un-traversed traversal route;

[0011] Calculate the difference between the length of the updated route and the length of the traversed route;

[0012] If the difference does not reach the preset extra length, update the traversed route according to the updated route, and then continue the inspection;

[0013] If the difference reaches the preset extra length, continue the inspection according to the traversed route; indirectly inspect the newly added power equipment sensor through the power equipment sensor that has been recently inspected.

[0014] By adopting the above technical solution, calculate the traversed route based on the existing power equipment sensors, conduct inspections according to the traversed route. When a newly added power equipment sensor is detected, in order to include the newly added power equipment sensor in the inspection, calculate the updated route. If the inspection workload will not increase too much, conduct the inspection according to the content of the updated route. If the inspection workload increases too much, establish a data link through the power equipment sensors that have been inspected, and indirectly inspect the newly added power equipment sensor, so as to be able to conduct inspections to master the working status of the power equipment sensors.

[0015] Preferably, in the steps of the indirect inspection, it includes:

[0016] Send indirect connection data to the currently connected power equipment sensor;

[0017] The currently connected power equipment sensor responds to the indirect connection data, and then establishes a communication link connection to the newly added power equipment sensor through the power equipment sensors that have been inspected; wherein, the indirect connection data includes the numbers and coordinates of the power equipment sensors in the communication link.

[0018] The newly added power equipment sensor responds to the indirect connection data to generate sensor readings, and returns the sensor readings through the communication link. If the sensor readings conform to the preset verification template, the indirect inspection ends.

[0019] By adopting the above technical solution, establish a communication link by identifying indirect connection data, which is conducive to realizing indirect inspection in terms of data.

[0020] Preferably, in the steps of the indirect inspection, it further includes:

[0021] The newly added power equipment sensor records the number of times of establishing the communication link;

[0022] Record the time interval between two adjacent times of forming the communication link;

[0023] Calculate an indirect reference degree based on the number of times and the time interval, where the indirect reference degree is set in an inverse correlation with the number of times and in a positive correlation with the time interval;

[0024] Adjust the additional length in a positive correlation with the indirect reference degree.

[0025] By adopting the above technical solution, calculate an indirect reference degree associated with the actual situation of indirect inspection according to the number of times of establishing a communication link and the time interval, and then adjust the additional length according to the indirect reference degree, so as to adjust the start standard of indirect inspection and achieve closed-loop adjustment of indirect inspection.

[0026] Preferably, in the steps of the indirect inspection, it further includes:

[0027] The newly added power equipment sensor records the number of times of forming a communication link. If the number of times is greater than a preset cumulative value within a preset time period, no new communication link will be formed.

[0028] By adopting the above technical solution, it is possible to avoid frequently establishing some duplicate communication links and reduce the hardware resources occupied by the power equipment sensor.

[0029] Preferably, in the step of no longer forming a new communication link, it further includes:

[0030] Identify the cumulative data generated by the newly added power equipment sensor. The cumulative data includes a cumulative quantity and cumulative content;

[0031] If the cumulative quantity is greater than a preset cumulative comparison value, a new inspection link will be established according to the cumulative content, and inspection will be carried out according to the inspection link.

[0032] By adopting the above technical solution, if the quantity of the newly added power equipment sensor is greater than the cumulative comparison value, a new inspection loop will be established and inspected in parallel with the existing inspection route.

[0033] Preferably, in the step of carrying out inspection according to the inspection link, it further includes:

[0034] Calculate the distance between the power equipment sensors corresponding to the inspection link in the traversal route;

[0035] Select the power equipment sensors with a distance less than a preset interconnection range and set them in pairs;

[0036] Form all the power equipment sensors set in pairs into a temporary verification queue;

[0037] Carry out data communication verification on the temporary verification queue;

[0038] If the results of the data communication verification are consistent, the power device sensors in the temporary verification queue return normal data to the corresponding links.

[0039] If the results of the data communication verification are inconsistent, the power device sensors in the temporary verification queue return abnormal data to the corresponding links, and the inspection link is merged into the traversal route and the traversal route is updated.

[0040] By adopting the above technical solution, if the distance between the traversal route and the inspection link is relatively close, the corresponding power device sensors are allowed to perform data communication verification, and the data communication verification is used to check whether the respective inspection information is abnormal.

[0041] Preferably, the method further includes:

[0042] When inspecting the power device sensors, obtain the infrared imaging data of the power device sensors;

[0043] Obtain the self-inductance information inside the power device sensors through infrared laser communication to form infrared laser data;

[0044] If the infrared imaging data and the infrared laser data form a preset corresponding relationship, continue the inspection;

[0045] Otherwise, mark the power device sensor and generate and return a marking information.

[0046] By adopting the above technical solution, it can be seen from the infrared imaging data whether the power device sensors are overheated abnormally, and the data information of the object can also be identified through the infrared laser data. If the data information corresponds to the information of the infrared imaging data, it means that the power device sensors are normal.

[0047] Preferably, in the step of obtaining the self-inductance information inside the power device sensors through infrared laser communication to form infrared laser data, it further includes:

[0048] First extract the temperature value in the infrared imaging data;

[0049] Adjust the frequency of the infrared laser communication according to the temperature value. The higher the temperature value, the higher the frequency.

[0050] By adopting the above technical solution, the higher the temperature, the greater the operation difficulty of the power device sensors. And in the case of a higher temperature, high-frequency infrared laser communication can still be carried out, indicating that the operation state of the power device sensors is good.

[0051] In a second aspect, the present application provides a dynamic monitoring system for power device sensors, adopting the following technical solution:

When a newly added power equipment sensor is detected, in order to include the newly added power equipment sensor in the inspection, calculate the updated route. If there are too many newly added power equipment sensors, increasing the inspection workload, establish a data link through the power equipment sensors that have been inspected, and indirectly inspect the newly added power equipment sensors, so as to be able to conduct inspections to master the working status of the power equipment sensors;

[0055] (2) Calculate the indirect reference degree according to the number of established communication links and the time interval to adjust the extra length, and realize closed-loop adjustment of indirect inspection;

[0056] (3) The traversal route and the inspection link can conduct inspections in parallel or let the corresponding power equipment sensors conduct data communication verification, and verify whether the respective inspection information is abnormal through data communication verification.

[0064] The following will further elaborate on the present application in conjunction with the attached Figures 1-6 Drawings.

[0065] The following will further describe the embodiments of the present application in detail with reference to the drawings of the specification.

[0066] An embodiment of the present application discloses a dynamic monitoring method for a power equipment sensor, as follows Figure 1 and Figure 6 as shown, based on the mobile inspection terminal 1, the mobile inspection terminal 1 has a communication module, and the power equipment sensor 2 to be inspected also has a corresponding communication module. When the mobile inspection terminal 1 conducts inspections on a predetermined route, it can automatically connect to the power equipment sensors 2 on or beside the route to observe the power equipment sensors 2 and conduct data communication.

[0067] Each installed power equipment sensor 2 will back up the attribute data in the background 3. The attribute data includes sensor data and location coordinates. The background 3 can use a management system within a local area network or a management system on the cloud. When installing the power equipment sensor 2, if two power equipment sensors 2 are adjacent within a preset distance range, these two power equipment sensors 2 will automatically scan the surrounding power equipment sensors 2 and measure distances. The linear distance of the surrounding range can be length data such as 10 meters, 20 meters, or 30 meters. If there are only two power equipment sensors 2 within the preset distance range, these two power equipment sensors 2 will automatically pair through the communication module and establish a data connection; if there are multiple power equipment sensors 2 within the preset distance range, the multiple power equipment sensors 2 will pair through the communication module and establish a data connection in sequence, and one power equipment sensor 2 will only connect to one power equipment sensor 2. Additionally, an independent power equipment sensor 2 can be used as the mobile inspection terminal 1 to conduct data communication with the power equipment sensors 2 passing by on the route during the movement of the power equipment sensor 2. After connecting a new observation module to the power equipment sensor 2, it can be used as a simple mobile inspection terminal 1.

[0068] As Figure 1 shown, the dynamic monitoring method includes the following steps:

[0069] The mobile inspection terminal 1 obtains the location coordinates of all power equipment sensors 2 through the background 3, and can calculate the traversal route for traversing all location coordinates in combination with existing geographical data or map data. The program for calculating the traversal route can run on the mobile inspection terminal 1 or in the background 3, and the background 3 directly sends the traversal route to the mobile inspection terminal 1.

[0070] Employees can carry out inspections according to the traversal route with the portable mobile inspection terminal 1. The portable mobile inspection terminal 1 can be installed on an AGV cart or a drone for inspections. The observation module of the portable mobile inspection terminal 1 includes an infrared imaging unit and an infrared laser communication unit. In addition to the communication module, the power equipment sensor 2 also has an infrared laser communication unit. The infrared imaging unit can capture the infrared image of the power equipment sensor 2, and the infrared laser communication unit can perform optical communication with the power equipment sensor 2. When inspecting the power equipment sensor 2, the portable mobile inspection terminal 1 obtains the infrared imaging data of the power equipment sensor 2 and also obtains the self-inductance information inside the power equipment sensor 2 through infrared laser communication to form infrared laser data. The self-inductance information includes the temperature value formed by self-measurement inside the power equipment sensor 2.

[0071] The portable mobile inspection terminal 1 processes and judges the infrared imaging data and the infrared laser data to determine whether the infrared imaging data and the infrared laser data form a preset corresponding relationship. The preset corresponding relationship can be whether the temperature value of the outer shell of the power equipment sensor 2 calculated from the infrared imaging data has too large a difference from the temperature value extracted from the infrared laser data. For example, if the difference is greater than 5°C, then there is no corresponding relationship; if the difference is less than or equal to 5°C, then there is a corresponding relationship.

[0072] During the processing, the portable mobile inspection terminal 1 first extracts the temperature value from the infrared imaging data, and then adjusts the frequency of the infrared laser communication according to the temperature value. The higher the temperature value, the higher the frequency. For example, when the temperature value is 25°C, the frequency of the infrared laser communication is 25 kHz. If the temperature value gradually rises to 25°C, the frequency of the infrared laser communication gradually rises to 35 kHz. The higher the temperature, the greater the operating difficulty of the power equipment sensor 2. And in the case of a higher temperature, the ability to perform infrared laser communication at a higher frequency indicates that the operating state of the power equipment sensor 2 is good.

[0073] It can be seen from the infrared imaging data whether the power equipment sensor 2 is overheated abnormally, and the data information of the object can also be identified through the infrared laser data. If the data information corresponds to the information of the infrared imaging data, it means that the power equipment sensor 2 is normal, and the inspection continues; otherwise, the portable mobile inspection terminal 1 marks the power equipment sensor 2, generates and records the marking information or returns the marking information to the background 3. Subsequently, the maintenance personnel can repair the marked power equipment sensor 2 according to the marking information in the portable mobile inspection terminal 1 or the background 3.

[0074] During the inspection process of the mobile inspection terminal 1, in addition to the existing power equipment sensors 2, it may also encounter power equipment sensors 2 that are being installed or have been recently installed. It may also encounter power equipment sensors 2 that have not communicated with the background 3 and were installed previously. Such power equipment sensors 2 can be regarded as newly added power equipment sensors 2, and the mobile inspection terminal 1 will obtain the joining coordinates of the newly added power equipment sensors 2.

[0075] If the mobile inspection terminal 1 obtains the joining coordinates, it will calculate the updated route based on the joining coordinates and the remaining un-traversed inspection route. The program for calculating the updated route can run on the mobile inspection terminal 1 or in the background 3. The mobile inspection terminal 1 will send the attribute data and joining coordinates of the newly added power equipment sensors 2 to the background 3, and the background 3 will directly send the updated route to the mobile inspection terminal 1.

[0076] The mobile inspection terminal 1 calculates the difference between the length of the updated route and the length of the traversed route. If the difference does not reach the preset additional length, the traversed route will be updated according to the updated route, and then the inspection will continue. If the difference reaches the preset additional length, the inspection will continue along the traversed route. The additional length can be set to 20 meters, 80 meters, or 200 meters. The additional length is used to measure whether the updated route makes the mobile inspection terminal 1 need to travel too long an extra distance. If the mobile inspection terminal 1 needs to travel too long, it is not conducive to the inspection work and will generate a large amount of redundant data. If the difference exceeds the additional length, the mobile inspection terminal 1 can indirectly inspect the newly added power equipment sensors 2 through the power equipment sensors 2 that have been recently inspected.

[0077] As Figure 2 shown, the specific steps of indirect inspection include: the mobile inspection terminal 1 can send preset indirect connection data to the currently connected power equipment sensors 2. After receiving the indirect connection data, the currently connected power equipment sensors 2 will check the indirect connection data according to the preset inspection parameters. If the check is successful, it will respond to the indirect connection data, and then the currently connected power equipment sensors 2 will establish a communication link through the nearest and data-connected inspected power equipment sensors 2, and let the mobile inspection terminal 1 be data-connected to the newly added power equipment sensors 2 through the communication link. Among them, the indirect connection data includes the numbers and coordinates of the power equipment sensors 2 in the communication link.

[0078] After the newly added power equipment sensor 2 receives the indirect connection data, it will check the indirect connection data according to the preset inspection parameters. If the check is successful, it will respond to the indirect connection data, and the newly added power equipment sensor 2 will respond to the indirect connection data to generate a sensor reading. The newly added power equipment sensor 2 returns the sensor reading to the mobile inspection terminal 1 through the communication link. The sensor reading can be the globally unique code built into the newly added power equipment sensor 2 or the self-induced information generated in real time. If the sensor reading conforms to the preset verification template, the indirect inspection ends. The preset verification template can be the format data of the globally unique code or the appropriate range of temperature values. If the globally unique code of the sensor reading is the content that conforms to the format data, it conforms to the template, otherwise it does not. If the temperature value of the sensor reading is within the appropriate range, it conforms to the template, otherwise it does not. The currently connected power equipment sensor 2 and the newly added power equipment sensor 2 establish a communication link between the mobile inspection terminal 1 and the newly added power equipment sensor 2 by identifying the indirect connection data, which is conducive to realizing indirect inspection on data.

[0079] Furthermore, in order to avoid establishing communication links that are of little use too frequently, as Figure 3 shown, the number of times of establishing a communication link is recorded in the memory inside the newly added power equipment sensor 2, and the time interval between two adjacent times of forming a communication link is also recorded. The recording period can be set to one day, one hour or ten minutes. The newly added power equipment sensor 2 calculates the indirect reference degree according to the number of times and the time interval. The indirect reference degree is set in an inverse correlation with the number of times, and the indirect reference degree is set in a positive correlation with the time interval. The calculated indirect reference degree is associated with the actual situation of the indirect inspection. The additional length is adjusted positively according to the indirect reference degree. After adjusting the additional length, the standard for establishing a communication link can be changed, so as to adjust the start standard of the indirect inspection and realize the closed-loop adjustment of the indirect inspection.

[0080] In addition, in order to avoid frequently establishing some duplicate communication links and prevent excessive occupation of the hardware resources of the power equipment sensor 2, the newly added power equipment sensor 2 records the number of times of forming a communication link. If the number of times is greater than the preset cumulative value within the preset time period, no new communication link will be formed. However, as Figure 4As shown, in order to be able to inspect more power equipment sensors 2 after starting the inspection work, if the quantity of newly added power equipment sensors 2 discovered by the connection of the mobile inspection terminal 1 is greater than the cumulative comparison value, a new inspection loop is created to perform parallel inspections with the existing inspection route. Each time the mobile inspection terminal 1 identifies a newly added power equipment sensor 2, cumulative data is generated, and the cumulative data includes the cumulative quantity and the cumulative content. If the cumulative quantity is greater than the preset cumulative comparison value, the mobile inspection terminal 1 can return the preset marker data to the background 3 according to the cumulative content. After receiving the marker data, the background 3 can start another mobile inspection terminal 1 and create a new inspection link, controlling the other mobile inspection terminal 1 to perform inspections according to the inspection link.

[0081] When at least two mobile inspection terminals 1 perform inspections according to their respective routes, it is also possible to establish an inter-inspection state between the power equipment sensors 2 on this route and that are relatively close, as Figure 5 shown. The specific steps for inter-inspection are as follows:

[0082] The background 3 can first calculate the distances between the power equipment sensors 2 corresponding to the inspection link in the traversal route. Here, the distance is the actual physical distance calculated by the background 3 based on the built-in physical map. Then, select the power equipment sensors 2 with distances less than the preset interconnection range and pair them up. Among them, the preset interconnection range can be length data such as 10 meters, 20 meters, or 30 meters. The background 3 then sends the data of the paired power equipment sensors 2 to the corresponding route or the mobile inspection terminal 1 that has passed through. The corresponding mobile inspection terminal 1 sends a teaming instruction to the paired power equipment sensors 2. The power equipment sensors 2 receive the teaming instruction and verify the teaming instruction through a pre-built inspection program. After verification, they scan the other paired power equipment sensor 2 and establish a connection, thus forming a temporary verification queue for all paired power equipment sensors 2.

[0083] The corresponding mobile inspection terminal 1 performs data communication verification on the verification queue. The teaming instructions in different mobile inspection terminals 1 are different. The data communication verification can be to verify the difference and format consistency of the teaming instructions. If the results of the data communication verification are consistent, the power equipment sensors 2 in the temporary verification queue return normal data to the corresponding link. If the results of the data communication verification are inconsistent, the power equipment sensors 2 in the temporary verification queue return abnormal data to the corresponding link, and the inspection link is merged into the traversal route and the traversal route is updated. On-site, there are many power equipment sensors 2 and strong electromagnetic interference. Therefore, strong anti-interference measures are required for data communication during the inspection process, especially for wireless communication. In addition to increasing the power of wireless communication, another measure is to enhance the verification steps for the transmitted data content. Therefore, adding the data communication verification step can further improve the stability of the inspection.

[0084] Based on the existing power equipment sensor 2, a traversal route is calculated, and inspection is carried out according to the traversal route. When a newly added power equipment sensor 2 is detected, in order to include the newly added power equipment sensor 2 in the inspection, an updated route is calculated. If the inspection workload is not increased too much, the inspection is carried out according to the content of the updated route. If the inspection workload is increased too much, a data link is established through the power equipment sensors 2 that have been inspected, and the newly added power equipment sensor 2 is indirectly inspected, so as to be able to realize the inspection to master the working state of the power equipment sensor 2. During the inspection process, if the number of newly added power equipment sensors 2 is too large, one mobile inspection terminal 1 cannot complete the inspection efficiently. In addition, a mobile inspection terminal 1 is required to perform parallel inspection according to the route newly established by the background 3, so as to improve the inspection efficiency and reduce the unreasonable occupation of hardware resources. The parallel inspection of the traversal route and the inspection link can not only improve the inspection efficiency, but also improve the accuracy of the inspection results. If the distance between the traversal route and the inspection link is relatively close and the power equipment sensors 2 on the corresponding routes can establish a connection, the corresponding power equipment sensors 2 are allowed to perform data communication verification, and the inspection information of each other is verified through the data communication verification to check whether there is an abnormality.

[0085] The embodiment of the present application also discloses a dynamic monitoring system for power equipment sensors, including the dynamic monitoring method of any one of the above-mentioned power equipment sensors.

[0086] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
