Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0025] The room distribution system is also called indoor signal distribution system. The cell covered by the room distribution system is called room distribution cell. The room distribution system can solve the problem of no mobile signal in closed space such as elevator and basement. The room distribution system can uniformly distribute the signal of the mobile base station in every corner of the room through the indoor antenna distribution system, so as to ensure that every area in the room can achieve ideal signal coverage, improve the call quality in the building, increase the mobile phone connection rate, and thus improve the mobile user experience. Through fault monitoring of the room distribution system, problems can be found and solved in time, so as to ensure the network quality of the room distribution cell. Generally, the specific structure of the room distribution system is as shown in Figure 1 The room distribution system mainly includes: a base station device, a plurality of room distribution devices (such as room distribution antennas) connected to the base station device, a plurality of room distribution cells determined by the signal coverage range of the room distribution devices, a building covered by the signal of the base station device, a server and a terminal device located in the building. The working principle of the room distribution system will be introduced below in combination with Figure 1

[0026] The building is composed of multiple floors, and the plurality of terminal devices can be distributed on different floors of the building. The plurality of room distribution devices can be distributed in different areas of different floors of the building, and thus the plurality of room distribution cells formed by the plurality of room distribution devices can cover different areas of the building. The terminal device can be a smart phone, a tablet computer, a notebook computer, a desktop computer, a television, etc. The base station device is also called a room distribution base station, which is a kind of micro base station and can provide wireless network for the terminal device in the plurality of room distribution cells of the target building. The terminal device accesses the wireless network of the base station device, so as to access the server and thus realize online business, etc.

[0027] Based on the above room distribution system, the technical solutions provided by the embodiments of the present application will be described in detail below in combination with the drawings.

[0028] The room distribution system fault detection method provided by the embodiments of the present application is used to solve the problem that the existing room distribution system fault detection method has single room distribution fault acquisition channel, which leads to inaccurate positioning of the fault area and low fault positioning efficiency.

[0029] ​The execution subject of the room distribution system fault detection method provided in the embodiments of the present application can be, but is not limited to, at least one of a room distribution server, a call quality monitoring server, a network operation server, a fault analysis server, and the like. In addition, the execution subject of the method can also be an application (APP) running on the servers or the system itself.

[0030] For ease of description, the implementation of the method is introduced below by taking the execution subject of the method as a fault detection system. It can be understood that the execution subject of the method as a fault detection system is only an exemplary description, and should not be understood as a limitation of the method.

[0031] The specific implementation flowchart of the room distribution system fault detection method provided in the present application is shown in FIG. 1, and mainly includes the following steps: Figure 2

[0032] Step 11: generating a three-dimensional building room distribution site distribution model according to the obtained building room distribution system site data and building data;

[0033] In an embodiment, the fault detection system can obtain the building room distribution system site data by querying the pre-stored room distribution system design data and design drawings. Specifically, the obtained building room distribution system site data can include the specific positions of device installation such as floor antenna position map, elevator antenna position map, basement antenna position, remote radio unit (RRU) installation position, and network parameter information such as building cell global identity (CGI) used by the building.

[0034] In addition, the fault detection system can obtain the building data by querying the pre-stored building architectural design data and design drawings. Specifically, the obtained building data can include the location (i.e., the latitude and longitude) of the building, the size (length, width, and height) of the building, and the height of the building.

[0035] ​The fault detection system utilizes the obtained building substation system site data and building data, utilizes a three-dimensional modeling software (for example, Revit software) to model the building, obtains a building information model (BIM), then exports the BIM data of the building from the Revit software, imports the BIM data into the Unreal 5 engine, obtains an Unreal building model, establishes a building equipment coding standard, maps and encodes the substation equipment in the building, obtains substation equipment coding data, utilizes OPC-UA technology to build a data interaction structure, maps the internal data of the building to the Unreal building model based on the substation equipment coding data, and obtains the digital twin model corresponding to the building, which is used as a three-dimensional building substation site distribution model for subsequent building substation system fault detection.

[0036] The OPC-UA is a standardized technical framework that uses Internet integration technology and does not depend on specific operating systems or hardware platforms. The OPC-UA can run in different environments, such as Windows, Linux, and embedded systems, and has independence, security, scalability, and modelability. Through information modeling, the OPC-UA supports the addition of new objects and functions in the address space without changing existing programs or services. The OPC-UA provides a rich information model that can represent various types of data and objects, supports complex structure and hierarchical modeling, and enables the integration of data from different sources and formats, meeting the data mapping needs of the digital twin model, improving data interoperability and reusability. The OPC-UA not only supports data access but also provides advanced functions such as alarm and event handling, historical data storage, and complex data processing, improving the intelligence of the digital twin model and the control ability of the building. The building control module contains the digital twin model, and controls the building based on the digital twin model.

[0037] It should be noted that the above scheme is only an example of modeling the three-dimensional building substation site distribution model. In addition to the above modeling method, the three-dimensional building substation site distribution model can also be generated by other modeling methods. The specific modeling scheme for generating the three-dimensional building substation site distribution model is not limited.

[0038] Step 12: According to the obtained terminal measurement report MR data, determine the distribution information of the terminal in the three-dimensional building substation site distribution model;

[0039] It should be noted that, since the 5G network currently cannot collect the minimization of drive tests (MDT) data of the terminal, the distribution position of the terminal in the three-dimensional building substation distribution model can only be determined by collecting the measurement report data (MR data) reported by the terminal.

[0040] The MR data is a measurement report generated when a user uses a mobile device to call, and records the user's cell location information, phone transmission power, cell network quality and other information. These data are collected by the base station of the operator and output as a Cell Trace Record file through the operational support system (OSS). In the embodiments of the present application, the measurement report MR data obtained can specifically include the following data: the CGI of the substation cell occupied by the terminal, the latitude and longitude of the terminal, the reference signal received power (RSRP) of the terminal, and the current height of the terminal and other information.

[0041] In the embodiments of the present application, the fault detection system can determine the floor distribution information and the specific area distribution information of the terminal in the building through the MR data uploaded by the terminal.

[0042] In the embodiments of the present application, the fault detection system can determine the floor distribution information and the floor area distribution information of the terminal according to the following sub-steps, specifically including:

[0043] Scheme a, determining the floor distribution information of the user terminal in the three-dimensional building substation distribution model in the building:

[0044] Sub-step 12-1-1, determining the minimum height data uploaded by the terminal corresponding to the building substation system;

[0045] In the embodiments of the present application, the fault detection system can obtain all user terminals accessing the current building base station device, receive the MR data uploaded by the user terminals, and then determine the minimum height data uploaded by the terminals accessing the building base station device according to the obtained MR data.

[0046] Sub-step 12-1-2, determining the first height data of the terminal in the building according to the height data corresponding to the terminal and the minimum height data;

[0047] It should be noted that, since some buildings are not built from sea level, for example, the first floor of some buildings corresponds to an altitude of 100 meters, in this case, when determining the specific floor corresponding to the equipment in the building, the construction altitude of the building itself needs to be subtracted, for example, in the above example, when determining the height of each terminal device in the building, 100 meters needs to be subtracted.

[0048] The height data uploaded by the terminal to be identified is determined, the height difference between the height data and the minimum height data is calculated, and then the height data of the terminal to be identified in the building is determined. Specifically, in the embodiments of the present application, the height of the terminal device in the building can be calculated according to the following formula [1]:

[0049] F n h=Eh (max) -Eh (min) [1]

[0050] Wherein, F n h is the height of the terminal device in the building, Eh (max) is the altitude data uploaded by the terminal device through the MR data, Eh (min) is the minimum height data uploaded by all terminals accessing the base station device of the building.

[0051] Sub-step 12-1-3, according to the building data, determining the floor height data of the building;

[0052] Sub-step 12-1-4, according to the first height data and the floor height data, determining the floor distribution information of the terminal in the three-dimensional building substation distribution model.

[0053] Dividing the height of the terminal device in the building determined by executing step 12-1-2 by the floor height, the floor distribution information of the terminal device in the building can be determined.

[0054] Through the above sub-steps, the fault detection system can determine the floor distribution information of all user terminals accessing the base station device of the current building in the building, and then determine the user terminal devices corresponding to each floor in the building through data clustering, and then the running state of the room distribution device corresponding to the floor can be accurately determined through the connection communication state of the user terminal devices belonging to the same floor.

[0055] In addition, it should be noted that in actual use, different room distribution devices (such as antennas) can be set in the same floor, each antenna has a corresponding signal coverage range, therefore, in the embodiments of the present application, in addition to determining the running state of each floor room distribution device, the running state of the room distribution device corresponding to each area of the floor also needs to be further determined.

[0056] In the embodiments of the present application, the fault detection system can determine the signal coverage range of each room distribution device according to the installation position of the room distribution device, and then cluster the user terminal devices on each floor according to the signal coverage range corresponding to each room distribution device on the floor, to obtain the user terminal devices within the signal coverage range of each room distribution device, and then accurately determine the running condition of the corresponding room distribution device in a specific area of the floor through the connection communication state of the user terminal devices belonging to the same signal coverage range of the room distribution device.

[0057] In an embodiment, the fault detection system can determine the floor area distribution information of each terminal device according to the following sub-steps, including:

[0058] Sub-step 12-2-1, obtaining the MR data uploaded by the terminal corresponding to the building room distribution system;

[0059] In the embodiments of the present application, according to the processing result of the above sub-step 12-1-4, the fault detection system can obtain the MR data corresponding to each terminal device on each floor according to the floor.

[0060] Sub-step 12-2-2, determining the latitude and longitude data corresponding to each terminal device on the floor according to the MR data;

[0061] Sub-step 12-2-3, determining the floor area distribution information of the terminal in the three-dimensional building room distribution site distribution model according to the latitude and longitude data and the building data.

[0062] Specifically, in the embodiments of the present application, the fault detection system can determine the floor area distribution of each terminal device on the floor according to the following method, including: determining the room distribution antenna position data corresponding to each floor in the three-dimensional building room distribution site distribution model according to the building room distribution system site data; dividing the area of each floor of the three-dimensional building room distribution site distribution model according to the room distribution antenna position, to obtain the floor partition; determining the floor partition corresponding to the terminal according to the latitude and longitude data, to obtain the floor area distribution information of the terminal in the three-dimensional building room distribution site distribution model.

[0063] In an embodiment, the fault detection system can obtain the latitude and longitude of the polygon polygon constituting the building area, and determine the latitude and longitude reported by each user terminal device, calculate the distance between the building polygon boundary and the latitude and longitude of the user terminal device, select the building polygon corresponding to the minimum distance value as the floor area of the user terminal device in the floor.

[0064] Through the above sub-steps, the fault detection system can determine the floor area distribution information corresponding to each floor terminal device, and then cluster each floor terminal device according to the floor area distribution information, so as to determine the user terminal device corresponding to each floor area in the floor. Since the floor area is determined according to the indoor antenna coverage position, if there is a fault in the indoor device in the floor area, the terminal data collected in the floor area will also be abnormal, so the accuracy of positioning the fault position is greatly improved, the time for troubleshooting and processing the fault is greatly shortened, and the timeliness is greatly improved.

[0065] Step 13, according to the MR data, performing fault identification on the building indoor system;

[0066] It should be noted that the method provided in the embodiments of the present application is mainly for fault detection of the indoor network building that has been constructed, but there is a greater possibility that the signal of the outdoor macro station will be occupied at special positions in the building, such as window edges. In order to avoid the influence of the signal of the outdoor macro station on the fault detection result, in the embodiments of the present application, before performing fault identification, the received MR data needs to be filtered first to eliminate the surrounding macro station signal and only keep the indoor network signal. In the embodiments of the present application, the measured full amount of CGI can be compared with the indoor CGI in the work parameters, and the number of MR sampling points can be used as the evaluation basis to eliminate non-indoor CGI.

[0067] In order to accurately identify the fault of each indoor device in the building, in the embodiments of the present application, the fault detection system can cluster each terminal device according to the distribution information corresponding to each user terminal device determined by executing the above step 12, to obtain the terminal devices in each area of each floor, and then perform fault identification on the specified area of the floor according to the MR data uploaded by the terminal devices in the floor area. Specifically, in the embodiments of the present application, the fault detection system can perform fault identification according to the following method, which includes: clustering the obtained MR data according to the distribution information to obtain floor partition MR data; and performing fault identification on the building indoor system according to the floor partition MR data.

[0068] It should be noted that when the room equipment in the building is running normally, the changes of each detection index in the MR data uploaded by the user equipment are relatively stable as a whole, and when the room equipment has a fault, the changes of each detection index in the MR data uploaded by the user terminal accessing the room equipment may be abnormal fluctuation, so in the embodiment of the application, the fault detection system can collect the MR data of the terminal equipment in each floor area according to a preset detection period, compare each index in the MR data in the detection period with the index of the historical period in the floor area, and then determine whether each index in the current detection period is abnormal according to the comparison result, and then determine whether the room equipment in the floor area has a fault according to the result.

[0069] In an embodiment, the fault detection system can specifically perform fault identification according to the following method, which includes: obtaining the floor partition MR data in the current detection period according to a preset fault detection period; obtaining the average floor partition MR data in the historical detection period; and performing fault identification on the building room distribution system according to the floor partition MR data in the current detection period and the average floor partition MR data.

[0070] In an embodiment, the fault detection system can perform fault detection on the building room distribution system according to the above fault identification method in the following dimensions, which includes:

[0071] 1. Reference Signal Received Power (RSRP) detection:

[0072] Suppose that the RSRP for a certain floor area in the current detection period is null, or the difference between the RSRP collected in the current detection period and the RSRP collected in multiple historical detection periods exceeds a preset threshold, then it can be determined that the room distribution equipment corresponding to the floor area has a fault.

[0073] 2. Signal to Interference plus Noise Ratio (SINR) detection:

[0074] According to the RSRP detection result, if the difference between the SINR in the current detection period and the SINR collected in the historical detection period exceeds a preset threshold, it can be determined that the SINR of the floor area decreases due to poor coverage, and the room distribution equipment corresponding to the floor area has a fault.

[0075] 3. User number detection:

[0076] Suppose that the user number in a certain floor area in the current detection period is null or 0, then it can be determined that the room distribution equipment corresponding to the floor area has a fault.

[0077] 4. MR sampling point number detection:

[0078] If the MR sampling point for a certain floor area in the current detection period is null or 0, it can be determined that the room distribution equipment corresponding to the floor area has a fault.

[0079] 5. MR weak coverage ratio detection:

[0080] Specifically, when the difference between the MR weak coverage ratio for a certain floor area in the current detection period and the MR weak coverage ratio collected in the historical detection period exceeds the preset threshold, it can be determined that the room distribution equipment corresponding to the floor area has a fault.

[0081] 6. 5G long-time residence example detection:

[0082] Specifically, when the difference between the 5G long-time residence example for a certain floor area in the current detection period and the 5G long-time residence example collected in the historical detection period exceeds the preset threshold, it can be determined that the room distribution equipment corresponding to the floor area has a fault.

[0083] Step 14, when the room distribution system fault is identified by executing step 13, according to the distribution information, the fault point corresponding to the room distribution system fault is marked on the three-dimensional building room distribution site distribution model;

[0084] In the embodiments of the present application, in order to better reflect the distribution of the fault room distribution equipment in the three-dimensional building room distribution site distribution model, in one implementation, the fault detection system can render the fault area on the three-dimensional building room distribution site distribution model according to the preset KPI index rendering rule.

[0085] In the embodiments of the present application, the KPI index rendering rule includes two variables: variable i and Project, and a constant r.

[0086] Wherein, variable i represents the index segmentation rendering number, i = (1, 2, 3, 4, …, n); constant r represents the initial rendering number of each index, which is 1 by default; Project represents the KPI index to be detected, which can include: RSRP, SINR, MR sampling point number, user number, MR weak coverage ratio and the like.

[0087] In the embodiments of the present application, the preset KPI index rendering rule can be shown in the following formula [2]:

[0088]

[0089] In the embodiment of the present application, the fault detection system can use digital twin technology to visualize the fault positioning process and result data in the three-dimensional building room distribution model through the rendering mechanism. By visualizing the network quality, the communication and understanding ability of the user with the network is enhanced, which helps to improve the problem positioning accuracy, early detection and early solution to reduce the network quality caused by equipment.

[0090] In order to avoid the problem of inaccurate positioning of faulty equipment, the three-dimensional building room distribution model can be generated according to the obtained building room distribution system site data and building data, and the distribution information of the terminal in the three-dimensional building room distribution model can be determined according to the obtained terminal measurement report MR data. Then, according to the distribution information of the MR data in the three-dimensional building room distribution model, the fault of the building room distribution system can be identified according to the building floor partition, and when the fault of the room distribution system is identified, the fault point corresponding to the fault of the room distribution system can be marked on the three-dimensional building room distribution model according to the distribution information. After the three-dimensional building room distribution model is generated according to the obtained building room distribution system site data and building data, the floors of the three-dimensional building room distribution model are partitioned according to the room distribution antenna position, and the corresponding floor and area of the terminal in the three-dimensional building room distribution model are determined according to the height data and latitude and longitude data reported by the terminal. If the room distribution equipment in a certain partition fails, the MR data collected in the partition will also be abnormal, and then the precise fault identification of the building room distribution system can be realized by monitoring the partition MR data. After the fault is identified, the corresponding distribution information of the MR data in the three-dimensional building room distribution model can be used to accurately locate the fault position, greatly improving the accuracy of the room distribution system fault detection and the fault handling efficiency.

[0091] In one embodiment, the present application also provides a room distribution system fault detection device to solve the problem of the existing room distribution system fault detection method that cannot accurately locate the fault area and has low fault positioning efficiency due to the single fault acquisition channel of the room distribution system. The specific structure diagram of the room distribution system fault detection device is shown in Figure 3 As shown in the figure, it includes a modeling unit 31, a terminal positioning unit 32, a fault identification unit 33 and a marking unit 34.

[0092] The modeling unit 31 is configured to generate a three-dimensional building substation distribution model according to the obtained building substation system site data and building data, wherein the building substation system site data includes substation equipment installation position data and network parameter information, and the building data includes building position data and building size data.

[0093] The terminal positioning unit 32 is configured to determine distribution information of the terminal in the three-dimensional building substation distribution model according to the obtained terminal measurement report (MR) data, wherein the distribution information includes floor distribution information and floor area distribution information.
