The invention provides a vehicle-mounted platform based on embedded software redundancy, and relates to the technical field of vehicle-mounted equipment, the vehicle-mounted platform comprises a railway special signal machine body and a control panel containing double CPUs, a peripheral circuit shares one set, an application layer software redundancy switching method is utilized, the two CPUs verify each other, one CPU is a main CPU, and the other CPU is a standby CPU, so that fault detection is realized while information synchronization is ensured. And when a fault occurs, an undisturbed switching function can be realized. Embedded software redundancy is added to double-CPU control and is applied to a vehicle-mounted platform, so that the fault-tolerant capability and the anti-interference capability of the vehicle-mounted platform can be enhanced, the fault recovery capability can be improved, the delay and the throughput can be optimized, and the reliability and the stability of the vehicle-mounted platform can be greatly enhanced.
本发明提供了一种基于嵌入式软件冗余的车载台,涉及车载设备技术领域,包括铁路专用信号机本体和一块含双CPU的控制板,外围电路共享一套,利用应用层软件冗余切换的方法,两个CPU相互校验,一主一备,保证信息同步的同时做到故障检测,使故障发生时可以实现无扰动切换功能。本申请把嵌入式软件冗余加到双CPU控制当中,并应用在车载台上,可以增强其容错能力、抗干扰能力,提升故障恢复能力,优化延迟和吞吐量,使其可靠性和稳定性大大增强。
