All other embodiments, which can be made by one of ordinary skill in the art without undue burden on the person of ordinary skill in the art based on the embodiments of the present invention, are within the scope of the present invention.
Fig. 1 shows a flow chart of a method for comprehensively evaluating rail transit vehicles according to an embodiment of the present invention, referring to fig. 1, the method includes:
S11, acquiring a vehicle type of a target vehicle, and determining an evaluation index set and an evaluation grade set according to the vehicle type, wherein the evaluation index set comprises evaluation indexes corresponding to the vehicle type, and the evaluation grade set comprises a state grade corresponding to each evaluation index;

For the steps S11 to S13, it should be noted that in the embodiment of the present invention, the vehicles in the track traffic include locomotives, coaches, trucks, motor trains, urban track traffic vehicles, and the like, and the vehicles need to be evaluated for the comprehensive status of each vehicle before or after a period of operation, so as to determine whether some devices or functions in the vehicles are good, and whether the vehicles can be continuously used.
Rail transit vehicles are of many types, such as locomotives, coaches, trucks, motor trains, and urban rail transit vehicles as mentioned above. There are different sets of evaluation indicators for different vehicle types.
However, in general, basic evaluation indexes are focused on equipment and functions such as a vehicle body, a bogie, a diesel engine, traction, control, braking, and on-vehicle electrical equipment.
In this embodiment, each evaluation index corresponds to a different state level. For example, the status ranks are bad, medium, good, and excellent. Generally, the number and content of the state levels corresponding to each evaluation index are the same.
And performing performance test (such as running, overhauling equipment and the like) on the target vehicle in the last period of time, collecting test data in the test process, and then obtaining a performance test score corresponding to each evaluation index in the evaluation index set according to the test data. The performance test score may be determined by a technician empirically analyzing the test data, or by a substantial analysis of the test data compared to standard information (e.g., curves, ranges of values).
After the performance test score corresponding to each evaluation index is obtained, the membership degree of each index close to different state grades is determined according to the performance test score, and then a comprehensive evaluation matrix is constructed according to the obtained membership degree. The comprehensive evaluation matrix comprises membership degrees of each evaluation index pointing to each state grade.
For example, the evaluation index in the evaluation index set is 5 items, and the state rank is 3 kinds.
R ij represents the membership of the ith evaluation index on the jth class state level. i is 1, 2, 3,4, 5.j is 1, 2, 3.
At this time, the obtained comprehensive evaluation matrix r= (R ij) 5*3.
And after the comprehensive evaluation matrix is obtained, determining an evaluation result vector according to the comprehensive evaluation matrix. In this regard, the purpose of the comprehensive evaluation matrix is to evaluate the state of the target vehicle. Therefore, the comprehensive evaluation matrix needs to be subjected to certain calculation transformation to obtain an evaluation result vector.
In the embodiment of the present invention, different evaluation indexes may have different weights for vehicles. Therefore, the required evaluation result vector can be obtained by calculating according to the weights of different evaluation indexes and the comprehensive evaluation matrix. And weighting the comprehensive evaluation matrix to obtain an evaluation result vector.

combining membership vectors corresponding to each evaluation index to obtain a comprehensive evaluation matrix;
wherein the state level criteria table includes a standard value for each state level.
In this regard, the above steps are explained below with specific examples:
The evaluation index of the selected vehicle was a braking state, and the performance test score of the braking state was 80. The standard state level table includes standard values 60, 70, 90 for each state level of the brake state.
At this time, the performance test score 80 of the braking state is calculated with each standard value to obtain the membership degrees corresponding to different state grades.
For example, a state class with a standard value of 60 has a membership of:
the membership of the state class with standard value of 70 is:
the membership of the state class with standard value 90 is:
According to the embodiment, the membership vectors corresponding to each evaluation index are combined to obtain the comprehensive evaluation matrix, so that the comprehensive evaluation matrix is combined with membership conditions of different state grades under multiple indexes, the indexes are closer to actual test conditions, and the follow-up accurate judgment of the comprehensive state of the target vehicle is facilitated.
