Description

Technical Field

[0002] With the increasing complexity and scale of base station systems, ensuring the stable operation of the system has become the key. Base station failures will not only affect the normal transmission of information, but may also cause significant economic losses and safety hazards. Therefore, it is particularly important to use effective fault diagnosis methods to quickly and accurately locate and solve base station failures. In the related art, fault diagnosis during base station signal transmission is triggered based on the fault message output by the base station equipment, that is, when the station receiving equipment cannot function normally due to the signal transmission function, it will output a fault message. When the fault diagnosis device connected to the base station receives the fault message, it triggers the operation of capturing the operating data of the current transmission signal of the base station equipment, and then performs fault diagnosis based on the captured operating data of the base station equipment. However, there is a long delay from the output of the fault message by the base station equipment to the collection of the operating data of the base station equipment, which leads to a long time interval between the collected operating data and the failure of the data transmission of the base station equipment, which leads to a low accuracy rate in locating the cause of the base station failure.

When it is detected that multiple sub-cache spaces in the target cache space are occupied, the information collection time corresponding to the sub-cache space is queried, and the information collection time is used to indicate the moment when the operating data of the target base station is cached in the current cache space. The information collection time of each sub-cache area is subtracted from the current moment to obtain a time difference, and the time difference is compared with the target threshold. The sub-cache space whose time difference is greater than or equal to the target threshold is determined as a candidate sub-cache space, and then the data stored in the candidate sub-cache space is released, that is, the historical cache data in the target cache space that is far away from the current moment is cleared first, and then the reference signal information and reference operation information collected at the current moment are filled into the candidate sub-cache space after the data is released, thereby achieving dynamic balance of the cache.

[0098] As an optional embodiment, locating the target fault cause that causes the target base station to fail to meet the transmission performance condition for the wireless radio frequency signal according to the target operation data includes:

[0099] The target fault cause corresponding to the target signal information and the target operation information is queried from the signal information, operation information and fault causes having a corresponding relationship, wherein the target operation data includes the target signal information and the target operation information, the target signal information is used to indicate the transmission performance of the wireless radio frequency signal transmitted by the target base station, and the target operation information is used to indicate the equipment operation status of the target base station when transmitting the wireless radio frequency signal.

[0100] Optionally, in an embodiment of the present application, the fault mapping table records the fault causes corresponding to the permutation and combination relationships of abnormal signal information and abnormal operation information. The acquired combination relationship of target signal information and target operation information can be matched with the permutation and combination relationship of abnormal signal information and abnormal operation information in the fault mapping table to obtain a matching result, and then the fault cause corresponding to the matching result is queried in the fault mapping table based on the matching result.

[0101] In order to better understand the above process, the above process is described below in conjunction with an optional embodiment, but it is not intended to limit the technical solution of the embodiment of the present application.

[0102] In this embodiment, a method for diagnosing and saving ecpri on-site faults is provided. Figure 3 is a schematic diagram of a fault location system according to an embodiment of the present application, such as Figure 3 As shown, the system includes a fault assessment system and a field collection system, and the structure is embedded in the uplink and downlink transceiver links. The fault assessment system monitors the ecpri status and the wireless uplink and downlink status, and the field collection system monitors the data and status between the uplink and downlink links and ecpri. Once the fault assessment system finds that the system deviates from the normal operating state, it will notify the data collection module to take action and save the information before and after the fault.

[0103] Figure 4 is a schematic diagram of a fault assessment system according to an embodiment of the present application, such as Figure 4 As shown in the figure, each subsystem of the system has a corresponding KPI module deployed under it. This module collects some key information of the subsystem, such as Figure 4 As shown, subsystem 1 has a total of N key parameters from a1 to an. These key parameters are considered as one of the signs of normal operation of the system during design. When the system is running, the maximum value a1_max of the normal range and the minimum value a1_min of the normal range, the specific process of calculating the failure probability is as follows:

[0104] (1) Renormalization controls the value between -1 and 1: Similarly, Bn and others are processed according to this logic.

[0105] (2) Merge S k =[A1,A2,…,A n ,B1,B2,…B i ,…+X1,X2,…,X j ]

[0106] (3) Calculation

[0107] (4) Set L1 = rulu(S k*w1+b1), set L2=relu([L1,ERROR]*w2+b2)

[0108] (5) Final output: output = softmax(L2*w3+b3)

[0109] Parameters w1, w2, w3, b1, b2, b3 are coefficients, which are obtained by training faulty and non-faulty samples in different situations during the experimental stage. The final output is a value of 0-1, representing the probability of a fault, 0 for 0% and 1 for 100%. When the output exceeds the set value of 60%, it is considered that a fault has occurred.

[0110] Figure 5 is a schematic diagram of a field acquisition system according to an embodiment of the present application Figure 1 ,like Figure 5 As shown, the acquisition module divides the data and system status on the time axis into time slices set by an artificial person. The data and status information in a time slice can be considered to occur at the same time. And this queue rolls over as time goes by.

[0111] Figure 6 is a schematic diagram of a field acquisition system according to an embodiment of the present application Figure 2 ,like Figure 6 As shown, once the fault assessment system finds the fault point, the acquisition system will enter another working mode, save the historical data before the fault point (T=-1, T=-2), and then collect new data to fill the other space (T=1, T=2).

[0112] For historical data before the failure point: T {-k} ,T {-k+1} ,…,T {-1} ,T0;

[0113] For historical data after the failure point: T {0} ,T {1} ,…,T {n} ,T n+1 ;

[0114] Final collection data: T {-k} ,T {-k+1} ,…,T {-1} ,T0,T {1} ,…,T {n} ,T n+1 .

[0115] Through the above content, the fault diagnosis + on-site saving system implemented by a single machine provides automated, high-real-time system diagnosis and fault saving functions. When the detection module finds that there is a fault point in the system, it will trigger the fault saving system in real time to record the system data information and fault information before and after the fault point. And the system runs automatically, providing high-real-time and information-rich fault diagnosis information in the field where it is inconvenient for other third-party equipment to intervene.

[0116] In summary, this solution automatically monitors the system status and saves a large amount of effective data in real time when a fault occurs, which greatly improves the cost and feasibility of fault diagnosis of the original technology.
