Research on Boot Problem and Automatic Repair of an Embedded Real-Time Operating System

At present, in the communication between Electric Multiple Units (EMU) and locomotive network control system, in order to ensure the stability of vehicle control and the accuracy and reliability of data recording, its key components - Central Control Unit (CCU) and Event Record Machine (ERM) adopt an embedded real-time operation system. In order to facilitate debugging, the system needs to start Microsoft's DOS system before being called to start. Based on the feedback of the embedded real-time operating system startup failure from each locomotive and rolling stock depot, this paper will elaborate on its startup process and propose a solution that can automatically repair the startup problem, which has been tested in the laboratory to prove that this method can effectively avoid the system startup failure.
