Abstract:

Locomotive is an important traction and transportation equipment in tunnel construction. A new type of controller technology and CAN bus technology are used in the design of the electrical control system of diesel locomotive. The highperformance TTC60 controller is regarded as the core of the control system designed. The control of the hydraulic system and the match of the engine power are realized by the communication among the CAN bus, the displayer and the engine controller. The controller program is developed by means of Codesys platform and the program that runs in the LED is developed based on Linux operation system. So far the commissioning of the electrical control system designed has been completed, which shows that the electrical control system designed has unique advantages in control function realization, manmachine interaction, safety and reliability.

Key words: TTC60, electrical control system, CAN, diesel locomotive
