Based on the electric performance requirement of the electric locomotive plug, detecting system for the electric locomotive plugs is designed. Simplifying the plugs with resistances, the system mathematic model of the detecting equipment is set up. Kinds of the factors of the system errors are analyzed and the nonlinear relationship between the circuit parameters of the detecting equipment and the performance of the system is studied. Optimal parameters of the detecting apparatus are gained through the combination of the subsection method and the optimization design by Matlab software. Ultimately the detecting equipment which is convenient and accurate is developed and is successfully used in the practical applications. The detecting results indicate that the system＇s errors are less than 3% within the whole detecting range and the system has satisfied precision needed.
