The invention discloses a staff
metabolism simulation system for ground comprehensive tests of a manned
spacecraft. The staff
metabolism simulation system mainly comprises an
oxygen concentration
simulation unit, a
carbon dioxide simulation unit, a
nitrogen simulation unit and a
humidity simulation unit. The staff
metabolism simulation system is connected with a sealed cabin through pipelines, and air circulates between the staff metabolism
simulation system and the sealed cabin of the manned
spacecraft. According to an input simulation staff number and each staff metabolism mode, a
control system calculates control targets of the heat production quantity, the
humidity production quantity, the
oxygen consumption quantity and the
carbon dioxide increase quantity in combination with a metabolism based
empirical formula, and controls a fan, a valve, a compressor, a
molecular sieve, a flow controller, a pump and a heater so as to achieve the control targets through data such as temperatures, pressure, flow and
oxygen concentration in an acquisition
system according to preset
control logic. Compared with staff metabolism simulation systems in prior art, the staff metabolism
simulation system has the advantages that no staffs are required for participating in the tests, and capacities of a
thermal control system and an environment
control system are simultaneously assessed; and compared with tests with the staff, test systems constructed by the staff metabolism simulation system are
safer, higher in flexibility, longer in continuous
running time and fuller in
product assessment, and do not occupy cabin volume.
