Abstract

The invention discloses a train transmission control unit characteristic curve evaluation method. The method comprises the following steps: S01, acquiring an actual characteristic curve of the train transmission control unit in a test process; s02, comparing the actual characteristic curve with a preset standard characteristic curve to obtain a difference degree; and S03, when the difference degree is within a preset threshold value, judging that the actual characteristic curve is normal, otherwise, judging that the actual characteristic curve is abnormal. The invention also discloses an evaluation system, which comprises an upper computer and a simulation test platform, and is characterized in that the simulation test platform is connected with the train transmission control unit to be tested and is used for realizing a simulation test; the upper computer is used for executing the steps of the evaluation method. The invention further discloses a device and a medium corresponding to the method. The method, the device, the system and the medium have the advantage of realizing characteristic curve performance evaluation.

Description

technical field [0001] The invention mainly relates to the technical field of train testing, in particular to a method, device, system and medium for evaluating a characteristic curve of a train transmission control unit. Background technique [0002] The traction characteristic curve of the train refers to the curve drawn by the relationship between the total traction force (adhesive traction force) and the speed of the train. For general trains, when the speed is the lowest, it is the time when the traction force is the largest, and then as the speed increases, the traction force decreases linearly. , until the constant power point is reached, then the train enters the hyperbola of constant power, and the tractive force continues to decrease until the upper limit of the constant power point. Generally, this upper limit is the maximum operating speed point of the locomotive. [0003] Traction characteristic curve and braking characteristic curve are two important parameter...

AI Technical Summary

Problems solved by technology

Although this evaluation method can judge whether the characteristic curve at this time meets the requirements to a certain extent, it cannot evaluate the performance of the characteristic curve

like figure 1 As shown, the two actual characteristic curves are in line with the original evaluation standard, but due to the difference between the two characteristic curves, the parameters of the transmission control unit cannot be adjusted according to which characteristic curve, or the corresponding standard characteristic curve cannot be obtained. Parameter information( figure 1 The uppermost curve corresponds to the upper boundary of design torque + 30% error, the lowermost curve corresponds to the upper boundary of design torque - 30% error, and the smooth curve in the middle is the design curve)
