The invention discloses a master-slave task synchronization method and device, a controller and a rail train, and relates to the technical field of rail transit, and the method comprises the steps that the current controller identifies the master-slave in-place condition on a case of the rail train; determining a system master control condition corresponding to the current controller according to the master-slave in-place condition; if the system master control condition is a master control state, generating an interrupt request according to a first preset time interval, performing synchronous task processing according to the interrupt request, and sending the interrupt request to other controllers in place; according to the invention, the system master control condition corresponding to the current controller is determined according to the identified master-slave in-place condition, so that automatic identification of the master and slave controllers is realized; one controller serving as a system master controller generates and sends the interrupt request to other controllers serving as system slave controllers, so that all the controllers can perform strict master-slave task synchronization according to the interrupt request of the system master controller, and the precision of master-slave task synchronization is improved.
本发明公开了一种主从任务同步方法、装置、控制器及轨道列车,涉及轨道交通技术领域,该方法包括:当前控制器识别轨道列车的机箱上的主从在位情况;根据主从在位情况,确定当前控制器对应的系统主控情况;若系统主控情况为主控状态,则按第一预设时间间隔生成中断请求,按照中断请求进行同步任务处理,并将中断请求发送给在位的其他控制器;本发明通过根据识别到的主从在位情况,确定当前控制器对应的系统主控情况,实现主从控制器的自动识别;通过作为系统主控制器的一个控制器生成并向作为系统从控制器的其他控制器发送中断请求,使得全部控制器能够按照系统主控制器的中断请求进行严格的主从任务同步,提高了主从任务同步的精度。
