Embodiment Construction
[0026] The tasks of the three-machine hot standby structure based on the TSC695 real-time operating system are mainly divided into five tasks, namely: mode control task, telemetry and remote control task, three-machine data exchange and comparison task, system management task and idle task. The mode control task is mainly responsible for data acquisition, attitude calculation and control, navigation calculation and guidance, system fault detection and processing, etc. Telemetry and remote control tasks mainly complete the processing of injected data and instructions, packaging of telemetry data, and packaging of data to be compared among three machines. The three-machine data exchange and comparison task mainly realizes the sending, receiving, comparison and two-out-of-three comparison data among the three single machines. The system management task is mainly responsible for monitoring the operation of the system, packaging the telemetry data of the operating system, setting t...
