[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the specification and claims, it is to be understood that the terms first, second, etc. in the specification and claims are only used for the purpose of describing the same technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, nor necessarily describing the order or time sequence. The terms are interchangeable where appropriate. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0019] See also Figure 1 , This embodiment provides a training device for wiring harness troubleshooting, including a first aviation plug module, a wiring harness simulation module, and a second aviation plug module connected in sequence;

[0020] The first aviation plug module and the second aviation plug module are distributed on both sides, and both include a number of pins of the same number; the wiring harness simulation module includes a simulation wiring harness with the same number of pins as any one side; fault points are randomly arranged on the simulation wiring harness; the pins on both sides are connected through the simulation wiring harness to form a measurement path, and the simulation wiring harness containing the fault point is determined by measuring the resistance between the pins on both sides and judging its fault type.

[0021] In the above scheme, there is a corresponding relationship between the first aviation plug module and the second aviation plug and the actual aviation plug of the aircraft. By simulating the actual wiring harness of the aircraft through the simulated wiring harness, the fault points on the simulated wiring harness can realize the fault simulation of the aircraft wiring harness. The trainees can conduct large-scale aircraft wiring harness troubleshooting training without field training, further cultivate the maintenance personnel's troubleshooting thinking and troubleshooting ability for aircraft wiring harnesses, and reduce the training cost.

[0022] See also Figure 2 This embodiment provides a training device for wiring harness troubleshooting. The first aviation plug module of the training device includes pins A1 to A20, the wiring harness simulation module includes simulated wiring harnesses 1 to 20; the second aviation plug module includes pins B1 to B20; specifically:

[0023] Analog wiring harness 1 connects pin A1 and pin B1; pin A1 and pin B1 are grounded; analog wiring harness 2 connects pin A2 and pin B8; analog wiring harness 3 connects pin A3 and pin B15; analog wiring harness 4 connects pin A4 and pin B4; analog wiring harness 5 connects pin A5 and pin B2; analog wiring harness 6 connects pin A6 and pin B20; analog wiring harness 7 connects pin A7 and pin B11; analog wiring harness 8 connects pin A8 and pin B3; analog wiring harness 9 connects pin A9 and pin B19; analog wiring harness 10 connects pin A10 and pin B12; analog wiring harness Harness 11 connects pin A11 and pin B5; harness 12 connects pin A12 and pin B17; harness 13 connects pin A13 and pin B18; harness 14 connects pin A14 and pin B14; harness 15 connects pin A15 and pin B16; harness 16 connects pin A16 and pin B10; harness 17 connects pin A17 and pin B6; harness 18 connects pin A18 and pin B13; harness 19 connects pin A19 and pin B9; harness 20 connects pin A20 and pin B7.

[0024] As an example, in one embodiment of the present invention, pins A1-A20 and pins B1-B20 are all grounded.

[0025] As a preferred implementation, the fault types include open circuit fault, short circuit fault, abnormal resistance fault and cross-interconnection fault.

[0026] It should be noted that when the fault type of the fault point of the simulated wiring harness is a cross-interconnection fault, the pins on both sides of the simulated wiring harness are actually connected differently from the circuit diagram, and the trainee needs to measure the resistance between the pins on both sides to determine the actual cross-interconnection situation.

[0027] The trainees determined the fault type of the fault point by measuring the resistance between the pins on both sides and comparing it with the resistance under normal conditions.

[0028] As an example, the trainee determines whether the simulated wiring harness 9 contains a fault point by measuring the resistance between pin A9 and pin B19. If the fault point is contained, the trainee further determines the fault type of the simulated wiring harness 9. When the resistance between pin A9 and pin B19 is consistent with its normal resistance value, the simulated wiring harness 9 is considered to contain no fault point. Otherwise, the simulated wiring harness 9 is considered to contain a fault point, and its fault type is further determined. When the resistance between pin A9 and pin B19 is close to infinity, it is considered that the fault point of the simulated wiring harness 9 is an open circuit fault type; when the resistance between pin A9 and pins B1~B20 of the second aviation module is close to zero, it is considered that the fault point of the simulated wiring harness 9 is a short circuit fault type; when the resistance between pin A9 and pin B19 can be measured, but compared with its normal resistance, it is larger or smaller, it is considered that the fault point of the simulated wiring harness 9 is an abnormal resistance fault type; when the resistance between pin A9 and pin B19 is close to zero, but when the resistance between pin A9 and pin B16 is not close to zero, it is considered that the fault point of the simulated wiring harness 9 is a cross-interconnection fault type. According to the circuit diagram, further measurement can be used to determine whether the fault point of the simulated wiring harness 15 is a cross-interconnection fault type.

[0029] Preferably, the embodiment of the utility model further provides a training system for troubleshooting aircraft wiring harnesses, comprising any one of the training devices for troubleshooting wiring harnesses as described above, and also comprising a fault setting device;

[0030] The fault setting device is connected in sequence with the practical training device for wiring harness troubleshooting;

[0031] The fault setting device randomly sets fault points for simulating the wiring harness.

[0032] In the above scheme, there is a corresponding relationship between the first aviation plug module and the second aviation plug and the actual aviation plug of the aircraft. The actual wiring harness of the aircraft is simulated by simulating the fault points on the simulated wiring harness, which can realize the fault simulation of the aircraft wiring harness. The fault setting device can randomly set the fault points for the simulated wiring harness to achieve a combination of various wiring harness faults. Trainees can conduct large-scale aircraft wiring harness troubleshooting training without field training, further cultivate maintenance personnel's troubleshooting thinking and troubleshooting ability for aircraft wiring harnesses, and reduce training costs.

[0033] The above is only a preferred embodiment of the present invention. The present invention is not limited to the above embodiment.
