[0046] First, the following contents are introduced:

[0047] Communication equipment is a kind of equipment that uses electrical signals as the transmission medium. Its various functional modules are connected by multiple circuit boards in series and parallel to achieve the corresponding functions. Due to the complex and changeable working environment, high requirements are placed on its stability, reliability and safety during operation. Especially with the increase of running time, communication equipment is prone to frequent failures. Usually, the failure occurs on the circuit board, and it is not just a single failure. When a compound failure occurs, due to the high integration of the circuit board, it is often necessary to directly replace the circuit board. This post-maintenance method not only delays the equipment's mission execution, but also wastes a lot of manpower and material resources. If the occurrence of failures can be predicted in advance and the expected degree of failure can be judged, corresponding maintenance measures can be taken in time to carry out maintenance according to the situation, which is of great significance to the safe and reliable operation of communication equipment.

[0048] The existing technology for fault degree classification diagnosis generally requires multiple quantitative and qualitative classification indicators, and determines the fault level based on the fault type. However, for communication equipment, its component composition structure is complex, and there are many circuit boards for each functional module. Its failure mode and cause are diverse and uncertain, and the fault type cannot be fully predicted. Therefore, the accuracy and reliability of determining the fault level of communication equipment using the existing fault level determination method are low, and there is a lack of a method and system for accurately grading communication equipment faults.

[0049] In view of the above-mentioned defects, the purpose of the present application is to provide a method, device and electronic device for determining the fault level of communication equipment, aiming to solve the problem of low accuracy and reliability caused by the fault level determination method of the prior art being not applicable to communication equipment.

[0050] Next, combine Figure 1 A method for determining the fault level of communication equipment provided in an embodiment of the present application is introduced.

[0051] Figure 1 is a flow chart of a method for determining a fault level of a communication device provided in an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0052] Step 100, obtaining historical operation fault data of the same type of communication equipment and establishing a fault data set;

[0053] Optionally, the same type of communication equipment may be a plurality of vehicle-mounted communication equipment, or a plurality of other types of communication equipment, which is not limited in the present application.

[0054] Optionally, the historical operation fault data may be various electrical signal data of the communication equipment, such as voltage, current, power and other related parameters known to those skilled in the art, which is not limited in the present application.

[0055] Optionally, a fault data set may be established, and after acquiring historical operation fault data of the same type of communication equipment, the data may be stored in the fault data set.

[0056] Step 110, constructing a circuit simulation model of each circuit board inside the same type of communication equipment, and expanding the fault data set based on the circuit simulation model;

[0057] In order to solve the problem of difficulty in obtaining a large number of fault data samples during the actual operation of communication equipment, the present application constructs a circuit simulation model of each circuit board inside the same type of communication equipment, and expands the fault data set based on the circuit simulation model, thereby improving the accuracy of the life prediction model.

[0058] Step 120, training a communication equipment remaining life prediction model based on the fault data set;

[0059] The present application constructs a communication equipment remaining life prediction model, uses voltage, current, power and other data in a fault data set as input to the remaining life prediction model, and outputs the remaining life prediction value to train the communication equipment remaining life prediction model.

[0060] Through the communication equipment remaining life prediction model, the remaining life can be used to comprehensively characterize the multiple failure modes of the communication equipment to improve the accuracy and reliability of determining the failure level of the communication equipment.

[0061] Optionally, the communication equipment remaining life prediction model can be any deep learning model, which is not limited in this application.

[0062] Step 130, inputting the electrical signal data of the target communication equipment into the trained communication equipment remaining life prediction model to obtain a life prediction value;

[0063] After the communication equipment remaining life prediction model is trained, the electrical signal data of the communication equipment whose fault level is to be determined, such as current, voltage, power, etc., can be input into the trained communication equipment remaining life prediction model to obtain its output life prediction value.

[0064] Step 140: Determine the fault level of the target communication equipment based on the life prediction value and the preset threshold.

[0065] After obtaining the life prediction value, it can be compared with the preset threshold value, and the failure level of the target communication equipment can be determined based on the comparison result.

[0066] The method for determining the fault level of communication equipment provided by the present invention can improve the accuracy and reliability of determining the fault level of communication equipment by training a remaining life prediction model based on fault data, using the remaining life to comprehensively characterize the multiple fault modes of the communication equipment, and dividing the fault level by the predicted remaining life value. By expanding the fault data set using a circuit simulation model, the difficulty in obtaining a large number of fault data samples during the actual operation of the communication equipment can be solved, thereby improving the accuracy of the life prediction model.

[0067] In some embodiments, the method for obtaining the preset threshold in step 140 includes:

[0068] Step 141, obtaining the fault degree evaluation index value of the target communication equipment and the weight coefficient of each evaluation index;

[0069] Optionally, the fault degree evaluation index values ​​of the communication equipment may include combat readiness, mission success, maintenance costs, resource support costs, and the like.

[0070] After obtaining the fault degree evaluation index values, it is also necessary to obtain the weight coefficients corresponding to each evaluation index.

[0071] Step 142, based on the fault degree evaluation index value and the weight coefficient, obtaining a comprehensive rating value of the fault degree of the target communication equipment;

[0072] Specifically, the calculation formula for the comprehensive rating value of the fault degree is as follows:

[0073]

[0074] Among them, Q is the comprehensive index value, X j is the evaluation index value, r j is the weight coefficient, and n is the number of evaluation indicators.

[0075] Step 143, based on the comprehensive rating index value of the degree of failure of each communication equipment of the same type, a fault degree classification threshold diagram is drawn to obtain two classification threshold inflection points, and the remaining life value of the communication equipment corresponding to each inflection point is used as a preset threshold.

[0076] In some embodiments, the method of obtaining the weight coefficient of each evaluation indicator in step 141 includes:

[0077] Based on the number of communication equipment of the same type and the number of fault degree evaluation indicators, a weight coefficient of each evaluation indicator is obtained.

[0078] Specifically, the calculation formula for the weight coefficient of each evaluation index is as follows:

[0079]

[0080] Among them, r j is the weight coefficient, m is the number of communication devices of the same type, n is the number of fault degree evaluation indicators, and ξ ij is the correlation coefficient between the j-th indicator of the i-th communication device and the optimal value of this indicator, ρ is the discrimination coefficient, is the reference index sequence, is the sequence of indicators to be compared.

[0081] In some embodiments, the fault levels include three levels: severe, moderate, and minor, and the preset thresholds include a first preset threshold and a second preset threshold, where the first preset threshold is greater than the second preset threshold. Step 140 includes:

[0082] Step 1401, if the life prediction value is not greater than the second preset threshold, the fault level of the target communication device is the severe level; or,

[0083] Step 1402, if the life prediction value is greater than the second preset threshold but not greater than the first preset threshold, the fault level of the target communication device is the moderate level; or,

[0084] Step 1403, if the life prediction value is greater than the first preset threshold, the fault level of the target communication device is the minor level.

[0085] For example, set the second preset threshold and the first preset threshold to A and B respectively, and A < B. The fault levels are divided according to the following method: if the remaining life value output by the life prediction model is not greater than A, the communication device corresponding to this remaining life value is in the severe fault level; if the remaining life value output by the life prediction model is greater than A but not greater than B, the communication device corresponding to this remaining life value is in the moderate fault level; if the remaining life value output by the life prediction model is greater than B, the communication device corresponding to this remaining life value is in the minor fault level.

[0086] In one embodiment, the fault level results of 10 communication devices of the same type are shown in Table 1 specifically.

[0087] Table 1 Fault level results of 10 communication devices of the same type

[0088] Group Remaining life Failure degree 1 18590 serious 2 78566 slight 3 26574 Moderate 4 73510 slight 5 18598 serious 6 76550 slight 7 64558 slight 8 76534 slight 9 28598 Moderate 10 76574 slight

[0089] In some embodiments, step 110 specifically includes:

[0090] Step 1101, based on the circuit principle diagrams of each circuit board inside the communication devices of the same type, construct a circuit simulation model;

[0091] Step 1102: inject multiple types of faults into the circuit simulation model, collect fault data of the circuit simulation model under multiple fault types, and add the data to the fault data set.

[0092] Specifically, the circuit schematic drawings of each circuit board inside the communication equipment are obtained, and according to the circuit schematic drawings of each circuit board of the communication equipment, the complete circuits of each circuit board are replicated using circuit simulation software such as Multisim, Cadence PSpice or Simulink, and then based on the simulated circuit, fault types are injected, including hard faults such as open resistor, short capacitor, open capacitor, short capacitor, open transistor lead wire, and soft faults that deviate from the nominal value of the component, and then based on the circuit simulation model in the fault state, various electrical signal data are collected and added to the fault data set.

[0093] In one embodiment, according to the circuit schematic drawing of a circuit board of a communication equipment, the characteristics and parameters of various components are obtained, and the circuit is replicated into the Multisim simulation model. Since the circuit board of the communication equipment contains a variety of rectifier circuits, filter circuits, power amplifier circuits, etc., the circuit structure is complex. When replicating, corresponding adjustments and optimizations can be made according to the actual situation, such as arrangement position, component connection lines, etc. After drawing the circuit, add measuring instruments, such as oscilloscopes, multimeters, etc.

[0094] In some embodiments, the communication equipment remaining life prediction model in step 120 or step 130 is a deep learning model based on a neural network.

[0095] Optionally, a long short-term memory network can be used to construct a prediction model. The specific parameters of the model construction can be adjusted in actual application, and this application does not limit this.
