Abstract

The invention discloses a method and device for managing threads in a control system. The method comprises the following steps of acquiring a periodic thread running in a current running period T in acontrol system; determining the maximum timeout time Tdead of each periodic thread running in the running period T, wherein the maximum timeout time Tdead is the determined time; and managing the periodic thread operated in the operation period T according to the maximum timeout time Tdead corresponding to the operation period T of each periodic thread.

Description

technical field [0001] The present application relates to the field of information processing, in particular to a method and device for managing threads in a control system. Background technique [0002] In train control systems such as high-speed railways and urban rail transit, as the functions of train control systems become increasingly large, train control systems are gradually implemented based on real-time operating systems. The real-time operating system schedules threads based on priority, and there are problems such as low-priority threads cannot be scheduled in time and thread blocking. Because the train control system has high requirements for safety and real-time performance, it is necessary to take effective measures to find out whether there are problems in the scheduling of periodic threads in the system in time, so as to ensure that the train control system can take necessary measures to ensure safety when the periodic threads are not scheduled in time.
