The invention discloses a dual-master mutual exclusion circuit based on a rail transit safety computing platform and a judgment method. The dual-master mutual exclusion circuit comprises an A-series computing module, a B-series computing module, an A-series relay and a B-series relay, wherein the A-series relay corresponds to the A-series calculation module, and the B-series relay corresponds to the B-series calculation module; the A-series calculation module and the B-series calculation module start to work after being electrified to drive the paired relays to be closed, the two relays are in an interlocking state, and a coil of only one relay is electrified at the same time; a main system and a standby system are determined by judging the working states of the two relays after power-on. The method effectively distinguishes the main and standby positions of the double-system module.
本发明一种基于轨交安全计算平台双主互斥电路及判定方法,所述双主互斥电路包括:A系计算模块、B系计算模块、A系继电器和B系继电器;其中,A系继电器对应于A系计算模块,B系继电器对应于B系计算模块;A系计算模块和B系计算模块在上电后开始工作,驱动对系继电器闭合,且两继电器为互锁状态,同一时刻仅有一个继电器的线圈是通电的;通过判断上电后两继电器工作状态确定主系和备系。本发明有效区分双系模块主备位置。
