A locomotive control system based on a Winpac controller and a realization method thereof

Abstract

The invention provides a locomotive control system based on a Winpac controller. The system comprises a Winpac controller, a signal input module, a signal output module, an excitation control module, and an HMI module. The signal input module, the signal output module, the excitation control module, and the HMI module are separately connected with a CPU of the Winpac controller. The method for realizing the locomotive control system based on the Winpac controller comprises the following steps of input and detection of a locomotive digital quantity and an analog quantity, and a locomotive logic control operation processing thread. The locomotive control system carries out locomotive fault judgments according to logic control operation results, and further determines whether the fault influences the normal traction of a locomotive. A constant power control output of the locomotive is maintained through controlling speed regulation of a diesel engine. Compared to locomotive control systems in the prior art, the locomotive control system based on the Winpac controller is strong in data processing and logical operation capabilities. The high-speed performance and the instantiality of the locomotive control system can be guaranteed. In addition, the demands for locomotive motion control, information transmission and network communications are satisfied.

Description

technical field [0001] The invention relates to the field of locomotive control, in particular to a locomotive control system based on a WinPac controller. [0002] The invention also relates to a realization method of the locomotive control system based on the WinPac controller. Background technique [0003] Existing locomotive control systems, especially microcomputer control systems for diesel DC shunting locomotives, are generally controlled based on single-chip microcomputer or PLC technology. Among them, the single-chip microcomputer has strong data processing ability, but weak logic operation ability; while PLC logic operation ability is strong, but also has Weak data processing capability, fewer communication methods and other shortcomings. The WinPac technology is an industrial control technology based on Windows CE5.0 operating system and RISC platform. It combines the advantages of single-chip microcomputer and PLC to form powerful data processing and logic opera...
