The invention designs a distributed control system based on an RS422-based system bus according to the characteristics of stratospheric airships and aiming at optimization of system reliability, stability, real-time performance and overall performance and the like, and particularly relates to a stratospheric airship task control subsystem. The stratospheric airship task control subsystem comprises an airship task control computer and a data conversion box. The data conversion box is mainly in charge of parameter acquisition of various sensors in an airship task control system and control command output for various actuators. The airship task control computer performs data and command interaction with the data conversion box through an RS422 bus so that all airship task subsystems can be controlled and monitored in a unified mode. The airship task control computer is provided with two parallel airship task control computer channels, wherein the channel A serves as a master control channel, the channel B serves as a hot backup of the master control channel, and output interfaces of controllers of the two channels output enabling through channel fault logic control.
