Description

Technical Field

[0001] This invention belongs to the field of maintenance and management technology, and in particular relates to a method and system for maintenance and management of digital television coverage broadcasting. Background Technology

[0002] To promote the digitalization, networking, and intelligentization of the radio and television wireless coverage network, existing technical solutions construct a management platform to achieve intelligent management of the wireless transmission stations corresponding to the coverage broadcast of digital television, thereby forming a manageable and controllable wireless transmission coverage network for radio and television and network audiovisual information.

[0003] However, in the maintenance and management of wireless transmission stations, existing technical solutions suffer from deviations in the reliability of power supply equipment. This can lead to fluctuations in the power supply of the wireless transmission station under certain circumstances. Therefore, during road testing, i.e., when using vehicles to monitor and analyze the signal quality of the wireless transmission station, how to dynamically adjust the power supply of the wireless transmission station to evaluate and process the signal quality under different power levels, and thus generate targeted maintenance and management solutions, has become an urgent technical problem to be solved.

[0004] To address the aforementioned technical problems, this application provides a method and system for the maintenance and management of digital television coverage broadcasting. Summary of the Invention

[0005] To achieve the objectives of this invention, the following technical solution is adopted:

[0006] Specifically, this application provides a method for maintenance and management of digital television coverage broadcasting, which includes:

[0007] S1 uses the power supply data of the power supply equipment of the wireless transmission station as a basis to test the wireless transmission station that needs to be tested in multiple power supply ranges, and uses it as the test target station. Based on the data of the test target station and the operating data of the wireless transmission base station in each power supply range, the power supply range for the test processing of the wireless transmission station is determined.

[0008] S2 performs test analysis and processing on the wireless transmission station based on the power supply range of the test processing, determines the signal variation deviation position in the broadcast coverage area of ​​the wireless transmission station based on the test analysis and processing results, and determines the optimized test station in different power supply ranges based on the signal variation deviation position data and the power supply range of the test processing of the wireless transmission station.

[0009] S3 determines a method for maintaining wireless transmission stations within the power supply range based on the test results at each test station within the power supply range.

[0010] The beneficial effects of this invention are as follows:

[0011] Based on signal variation deviation location data and the power supply range of the test processing of wireless transmission stations, optimized test stations are determined within different power supply ranges. This involves considering the historical operating time of the wireless transmission base station within the power supply range, as well as the differences in the reliability of signal variation deviation location identification and processing due to the number of power supply ranges in the test processing. Furthermore, by combining the number of signal variation deviation locations, wireless transmission stations with abnormal signal variations, long operating times within the power supply range, and low reliability in identifying and processing signal variation deviation locations are screened. This achieves differentiated test processing, improving the efficiency and targeting of the test processing.

[0012] Based on the test results from various test stations within the power supply range, a method for maintaining wireless transmission stations within this range is determined. This method considers both the signal variation deviation location data of each test station within the power supply range to assess the degree of signal anomaly, and further considers the deviation of signal variation deviation location from other power supply ranges. This enables differentiated processing of the degree of signal anomaly within the power supply range compared to other power supply ranges. Consequently, the maintenance method is determined from the perspective of the degree of signal anomaly and the number of test stations, improving the targeting and reliability of the maintenance process and ensuring the reliability of digital television data transmission.

[0013] Furthermore, the power supply data of the power supply equipment is determined based on the historical changes in the power supply power of the power supply equipment of the wireless transmission station.

[0014] Furthermore, the method for determining the target test station is as follows:

[0015] Based on the power supply data of the power supply equipment of the wireless transmission station, determine the changes in the power supply power of the power supply equipment of the wireless transmission station in history.

[0016] The power fluctuation period of the wireless transmission station is determined based on the aforementioned fluctuations;

[0017] Based on the power fluctuation period data, determine whether the wireless transmission station is the test target station.

[0018] Furthermore, the power fluctuation period refers to the period when the power supply is unstable. Specifically, the period when the duration of power supply is not under the preset power supply does not meet the requirements is defined as the power fluctuation period.

[0019] Furthermore, when the interval between different power fluctuation periods is less than the preset duration, the wireless transmission station is determined to be the test target station because its power supply reliability is not high.

[0020] Furthermore, the method for determining the method for performing maintenance processing of the wireless transmission station within the power supply range is as follows:

[0021] The number of test stations in the power supply range is determined based on the test results at each test station within the power supply range.

[0022] Based on the test results at different test stations, determine the number of signal variation deviation locations at different test stations within the power supply range and the deviation from the signal variation deviation locations in other power supply ranges.

[0023] The method for determining the maintenance of wireless transmission stations within the power supply range is based on the deviation conditions used to identify abnormal variation test base stations within the power supply range, the number of test stations within the power supply range, and the number of signal variation deviation locations among different test stations within the power supply range.

[0024] In a second aspect, the present invention provides a computer system comprising: a memory and a processor connected in communication, and a computer program stored in the memory and capable of running on the processor, wherein the processor executes the aforementioned method for maintenance and management of digital television coverage broadcasting when running the computer program.

[0025] Other features and advantages will be set forth in the following description, and the objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0032] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0033] In this application, by analyzing the changes in the location of signal anomalies of the wireless transmission base station within different power supply ranges and within the rated power supply range, the maintenance and management strategy for the wireless transmission base station within the power supply range is determined, thereby improving the efficiency and timeliness of maintenance and management.

[0034] Example 1

[0035] like Figure 1 As shown, this application provides a method for maintenance and management of digital television coverage broadcasting, specifically including:

[0036] S1 uses the power supply data of the power supply equipment of the wireless transmission station as a basis to test the wireless transmission station that needs to be tested in multiple power supply ranges, and uses it as the test target station. Based on the data of the test target station and the operating data of the wireless transmission base station in each power supply range, the power supply range for the test processing of the wireless transmission station is determined.

[0037] Furthermore, the power supply data of the power supply equipment is determined based on the historical changes in the power supply power of the power supply equipment of the wireless transmission station.

[0038] Specifically, such as Figure 2 As shown, the method for determining the test target station is as follows:

[0039] Based on the power supply data of the power supply equipment of the wireless transmission station, determine the changes in the power supply power of the power supply equipment of the wireless transmission station in history.

[0040] The power fluctuation period of the wireless transmission station is determined based on the aforementioned fluctuations;

[0041] Based on the power fluctuation period data, determine whether the wireless transmission station is the test target station.

[0042] It is understood that the power fluctuation period refers to the period when the power supply is unstable. Specifically, the period when the duration of the power supply is not below the preset power supply does not meet the requirements is defined as the power fluctuation period. Specifically, the period when the duration of the power supply is not below the preset power supply is greater than 0.7 is defined as the power fluctuation period. The preset power supply is the rated power supply of the wireless transmission station.

[0043] It should be noted that when the interval between different power fluctuation periods is less than the preset duration, the power supply reliability is not high, and therefore the wireless transmission station is determined as the test target station.

[0044] In one possible embodiment, if the average duration of the interval between different power fluctuation periods is less than 2 hours, then the duration of the interval between different power fluctuation periods is determined to be less than a preset duration. It should be noted that the power fluctuation period is 1 hour.

[0045] Optionally, the method for determining the test target station is as follows:

[0046] Based on the power supply data of the power supply equipment of the wireless transmission station, determine the changes in the power supply power of the power supply equipment of the wireless transmission station in history.

[0047] Based on the aforementioned changes, determine the variation in power supply of the wireless transmission station at different monitoring times compared to the previous monitoring time, and based on the variation, determine the changing monitoring time within the monitoring time.

[0048] Based on the change monitoring time data, determine whether the wireless transmission station is the test target station.

[0049] It should be noted that the change monitoring time is the monitoring time when the ratio of the absolute value of the change to the power supply of the previous monitoring time is greater than 0.05. When the average number of monitoring times between different adjacent change monitoring times is less than 5, the wireless transmission station is determined to be the test target station.

[0050] It is understandable that wireless transmission stations need to be tested and processed within multiple power supply ranges, specifically:

[0051] Based on the rated power of the wireless transmission station, 0.905 times the rated power and 1.105 times the rated power are used as endpoint values ​​to obtain the test interval. The test interval is divided into equal intervals based on 0.01 times the rated power to obtain the power supply interval. The power supply power of the test processing within the power supply interval is determined by the average value of the endpoint values ​​of the power supply interval in different power supply intervals.

[0052] Specifically, it is divided into power supply ranges with endpoints from 0.905 times the rated power supply to 0.915 times the rated power supply, from 0.915 times the rated power supply to 0.925 times the rated power supply, and up to 1.095 times the rated power supply to 1.105 times the rated power supply.

[0053] Specifically, such as Figure 3 As shown, the method for determining the power supply range for the test processing of the wireless transmission station is as follows:

[0054] The number of test target stations is determined based on the test target station data;

[0055] Based on the operating data of the wireless transmission base station in each power supply range, the percentage of the operating time of the wireless transmission base station in each power supply range in history is determined.

[0056] Using the percentage of runtime and the number of target test stations, the power supply range for the test processing of the wireless transmission station is determined.

[0057] It should be noted that when the number of target test stations meets the requirements, the reliability of the test processing is relatively high. Therefore, the power supply range of the test processing for different wireless transmission stations is the rated power supply range, that is, the range between 0.995 times the rated power supply and 0.105 times the rated power supply.

[0058] In one possible embodiment, when the number of test target stations is not less than 5, the reliability of the test process is determined to be high, that is, the number of test target stations meets the requirements.

[0059] It should also be noted that when the number of target test stations does not meet the requirements, the matching test power range is determined by the percentage of the runtime of the wireless transmission base stations in history within each power supply range. Specifically, the power supply range with a runtime percentage greater than 0.1 is used as the matching test power range.

[0060] Specifically, based on the number of target test stations, a threshold for the percentage of runtime in the matching test power range is determined. The more target test stations there are, the larger the threshold for the percentage of runtime. In one possible embodiment, when the number of target test stations is between 2 and 4, including endpoints, the threshold for the percentage of runtime is 0.3. In other cases, it is 0.2. The matching test power range with a percentage of runtime greater than the threshold for the percentage of runtime is taken as the power supply range for the test processing of the wireless transmission station.

[0061] Optionally, the method for determining the power supply range of the test processing of the wireless transmission station is as follows:

[0062] The number of test target stations is determined based on the test target station data;

[0063] Based on the operating data of the wireless transmission base station in each power supply range, the percentage of the operating time of the wireless transmission base station in each power supply range in history is determined.

[0064] Based on the number of target test stations, a threshold for the percentage of runtime in the test power range is determined. Using the thresholds for the percentage of runtime and the percentage of line time, the power supply range for the test processing of the wireless transmission station is determined.

[0065] It should be noted that the power range in which the percentage of runtime exceeds the threshold for the percentage of runtime is used as the power supply range for the test processing of the wireless transmission station.

[0066] S2 performs test analysis and processing on the wireless transmission station based on the power supply range of the test processing, determines the signal variation deviation position in the broadcast coverage area of ​​the wireless transmission station based on the test analysis and processing results, and determines the optimized test station in different power supply ranges based on the signal variation deviation position data and the power supply range of the test processing of the wireless transmission station.

[0067] Furthermore, based on the power supply range of the aforementioned test processing, the wireless transmission station undergoes test analysis and processing, specifically including:

[0068] Within the power supply range of the test process, the test power is determined based on the average of the upper and lower endpoints of the power supply range. Under the test power, a test analysis process is performed to determine the signal quality at different locations within the broadcast coverage area of ​​the wireless transmission station using a mobile vehicle.

[0069] Furthermore, the signal variation deviation position is the location where the signal quality variation in different power supply ranges of the test process and the rated power supply range does not meet the requirements. The signal quality is determined based on the modulation error rate or the bit error rate. When the absolute value of the signal quality variation between the power supply ranges of different test processes at the location is greater than 0.07 compared with the maximum value of the signal quality in the rated power supply range, the location is determined as the signal variation deviation position.

[0070] Furthermore, the method for determining the optimized test station for testing within the power supply range is as follows:

[0071] Based on the signal variation deviation location data, the number of signal variation deviation locations of the test station is determined;

[0072] Based on the power supply range of the test processing of the wireless transmission station, identify wireless transmission stations with at least two power supply ranges for the test processing and use them as multi-dimensional test stations.

[0073] By utilizing the number of signal variation deviation locations of the multi-dimensional test stations, the operating data within the power supply range, and the distribution of the multi-dimensional test stations among the wireless transmission stations, the optimal test stations for test processing within the power supply range are determined.

[0074] It should be noted that the multi-dimensional test station includes the test target station and wireless transmission stations that do not belong to the test target station and have at least two power supply ranges for test processing.

[0075] It should be noted that when the distribution of the multi-dimensional test stations in the wireless transmission stations does not meet the requirements, that is, when the proportion of the multi-dimensional test stations in the wireless transmission stations is less than 0.2, the reliability of the test processing within the power supply range is not good. Therefore, based on this, in the multi-dimensional test stations at locations with signal variation deviations, all power supply ranges belong to the power supply range of the test processing.

[0076] Additionally, it is understood that when the distribution of the multi-dimensional test stations in the wireless transmission stations meets the requirements, it is also necessary to determine whether the number of signal variation deviation positions of the multi-dimensional test stations meets the requirements. Specifically, when the number of signal variation deviation positions of the multi-dimensional test stations is greater than a preset deviation position number threshold, which may be greater than 20 in one embodiment, then, based on this, in the multi-dimensional test stations where the number of signal variation deviation positions is greater than the preset deviation position number threshold, all power supply ranges are included in the power supply range for testing.

[0077] Furthermore, when the number of signal variation deviation positions of the multi-dimensional test station is not greater than the preset deviation position number threshold, it is also necessary to determine the number of signal variation deviation positions of the multi-dimensional test station and the percentage of runtime in the history of the power supply range. Specifically, when the number of signal variation deviation positions of the multi-dimensional test station is between 8 and 20, and the percentage of runtime in the history of the power supply range is greater than 0.1, then in the multi-dimensional test station, the power supply range with a percentage of runtime in the history greater than 0.1 is taken as the power supply range for test processing.

[0078] Optionally, the method for determining the optimized test station for the test processing within the power supply range is as follows:

[0079] Based on the signal variation deviation location data, the number of signal variation deviation locations of the test station is determined;

[0080] Based on the power supply range of the test processing of the wireless transmission station, identify wireless transmission stations with at least two power supply ranges for the test processing and use them as multi-dimensional test stations.

[0081] Based on the operating data of the multi-dimensional test station within the power supply range, the percentage of operating time in the history of the power supply range is determined. Based on the percentage of operating time, the number of signal variation deviation locations, and the distribution of the multi-dimensional test station among the wireless transmission stations, the optimal test station for test processing within the power supply range is determined.

[0082] Understandably, based on the proportion of multi-dimensional test stations in the wireless transmission stations, a first preset threshold and a second preset threshold are determined for the number of signal variation deviation positions. When the number of signal variation deviation positions of the multi-dimensional test stations is greater than the first preset threshold, all power supply ranges are included in the power supply range for test processing. When the number is greater than the second preset threshold, the power supply range with a historical running time proportion greater than 0.1 is taken as the power supply range for test processing.

[0083] It should be noted that the test stations for the power supply range include the test target stations and the optimized test stations for the power supply range that belong to the power supply range of the test processing.

[0084] S3 determines a method for maintaining wireless transmission stations within the power supply range based on the test results at each test station within the power supply range.

[0085] Specifically, the test results include the number of signal variation deviation locations within the power supply range and the similarity of these locations to those within other power supply ranges.

[0086] Specifically, the method for determining the maintenance process of the wireless transmission station within the power supply range is as follows:

[0087] The number of test stations in the power supply range is determined based on the test results at each test station within the power supply range.

[0088] Based on the test results at different test stations, determine the number of signal variation deviation locations at different test stations within the power supply range and the deviation from the signal variation deviation locations in other power supply ranges.

[0089] The method for determining the maintenance of wireless transmission stations within the power supply range is based on the deviation conditions used to identify abnormal variation test base stations within the power supply range, the number of test stations within the power supply range, and the number of signal variation deviation locations among different test stations within the power supply range.

[0090] It should be noted that when the number of test stations within the power supply range does not meet the requirements, that is, when the number of test stations within the power supply range accounts for less than 0.2% of the total number of wireless transmission stations, the reliability of the test results is difficult to meet the requirements due to the small number of test stations within the power supply range. Therefore, maintenance of the wireless transmission stations will be carried out whenever the number of wireless transmission stations within the power supply range that have a lower percentage of running time in the most recent preset time period does not meet the requirements, or whenever the number of wireless transmission stations within the power supply range that have a higher percentage of running time in the most recent preset time period does not meet the requirements.

[0091] It is understood that when there are more than 3 wireless transmission stations with an operating time ratio greater than 0.3 in the most recent month within the power supply range, or when there are more than 3 wireless transmission stations with an operating time ratio greater than 0.1 in the most recent month within the power supply range, maintenance processing of the wireless transmission stations will be carried out. That is, maintenance processing will be carried out on the wireless transmission stations with an operating time ratio greater than 0.1 in the most recent month within the power supply range to ensure that they operate within the rated power supply range.

[0092] Additionally, it is understood that when the number of test stations within the power supply range meets the requirements, if the number of signal variation deviation positions in different test stations within the power supply range also meets the requirements (i.e., the number of signal variation deviation positions in different test stations is less than 5), then it indicates that the wireless transmission stations within the power supply range are operating stably. Therefore, based on this, regardless of the operating time within the power supply range, no maintenance is required for the wireless transmission stations.

[0093] Furthermore, when there are test stations with a signal variation deviation that do not meet the requirements, if the number of test stations with a signal variation deviation of not less than 5 points accounts for more than 0.6% of the total number of test stations within the power supply range, then maintenance is required for any wireless transmission station within the power supply range that has a running time percentage greater than a preset percentage threshold in the most recent preset time period, even if it is operating within the rated power supply range.

[0094] Furthermore, if the number of test stations with signal variation deviations does not meet the requirement but the number of test stations meets the requirement, it is necessary to further identify abnormal variation test stations. In one possible embodiment, the abnormal variation test station is the station with the most signal variation deviations within the power supply range. If the number of abnormal variation test stations does not meet the requirement, that is, if the number of abnormal variation test stations is more than 2, then as long as there is a wireless transmission station within the power supply range whose operating time percentage is greater than a preset percentage threshold in the most recent preset time period, maintenance processing of the wireless transmission station is required, even if it is operating within the rated power supply range.

[0095] If there are abnormal changes in the test stations, maintenance will be carried out on the wireless transmission stations if the percentage of their operating time within the power supply range does not meet the requirements, or if the number of wireless transmission stations with a percentage of operating time greater than the preset percentage threshold within the power supply range does not meet the requirements.

[0096] Furthermore, if there are no abnormal changes in the test base station, when the number of test stations with signal deviation positions that do not meet the requirements has a proportion of running time in the most recent preset period within the power supply range that is greater than a preset percentage threshold, maintenance processing will be performed on the test stations with signal deviation positions that do not meet the requirements, and other wireless transmission stations will not need to be maintained.

[0097] Optionally, the method for determining the method for performing maintenance processing of the wireless transmission station within the power supply range is as follows:

[0098] Based on the test results of each test station within the power supply range, the number of test stations in the power supply range is determined, and the proportion of the test stations among all wireless transmission stations is used as the test ratio.

[0099] Based on the test results at different test stations, the number of signal variation deviation locations at different test stations within the power supply range is determined. Based on the number of signal variation deviation locations, test stations that do not meet the requirement for the number of signal variation deviation locations are identified and designated as deviation test stations.

[0100] Based on the test results at different test stations, the deviation of the signal variation deviation position between the test station and other power supply ranges is determined. The deviation is used to identify abnormal variation test base stations within the power supply range. Based on the abnormal variation test base stations, the test ratio, and the number of deviation test stations, a method for maintaining and processing wireless transmission stations within the power supply range is determined.

[0101] It should be noted that the deviation test station is a test station with no less than 5 signal variation deviation positions.

[0102] Additionally, it is understood that when the test ratio does not meet the requirements, maintenance of the wireless transmission stations will be carried out as long as the number of wireless transmission stations whose operating time ratio within the power supply range does not meet the requirements in the most recent preset time period, or the number of wireless transmission stations whose operating time ratio within the power supply range is greater than the preset threshold does not meet the requirements.

[0103] Furthermore, when the test ratio meets the requirements, and when there are no abnormally changing test base stations or deviation test stations, then regardless of the operating time within the power supply range, no maintenance is required for the wireless transmission transmitter station.

[0104] Furthermore, when there are abnormal change test base stations and deviation test stations, if the sum of the number of abnormal change test base stations and deviation test stations does not meet the requirements, that is, it is greater than the preset number threshold, then as long as there is a wireless transmission station in the power supply range within the most recent preset time period whose operating time ratio is greater than the preset ratio threshold, maintenance processing of the wireless transmission station is required, even if it is operating within the rated power supply range.

[0105] Additionally, it should be noted that if the sum of the number of abnormal change test base stations and deviation test stations meets the requirements, when the percentage of the operating time of an abnormal change test base station or deviation test station within the power supply range in the most recent preset time period is greater than a preset percentage threshold, maintenance processing will be performed on the abnormal change test base station or deviation test station whose percentage of operating time in the most recent preset time period is greater than the preset percentage threshold. Other wireless transmission stations do not need to be maintained.
