Research on Criteria Acquisition Method of Automatic Interpretation Software for Manned Spacecraft

In order to achieve fast and accurate acquisition of spacecraft automatic interpretation software criteria under multiple constraints, firstly, the state set, input set, and output set models are established based on the finite state machine(FSM) principle using structured data such as remote control commands, telemetry parameters, and normal value ranges in database. Subsequently, based on the mapping relationship between the telemetry change process and the FSM, a graphical criterion model is generated, using changes in equipment operating conditions as state variables and remote control commands, injection, and other events as input signals. Then, by using test history data to drive the state transition of FSM for model solving, transforming the “criterion generation” problem into the process of solving the state transition function. Finally, a set of state transition functions will be obtained, and operational criteria will be generated based on specific syntax rules. Taking the telemetry and control subsystem of the Chinese space station as an example, the algorithm is validated, which has certain engineering guiding significance.
