The invention provides a helicopter high-temperature air-entraining oxygen production control device and method. Comprising an engine air entraining channel (14), the outlet end of the engine air entraining channel (14) is connected with the inlet end of a heat dissipation assembly (3), the outlet end of the heat dissipation assembly (3) is connected with an inlet of an oxygen generation main machine (7) through an air entraining pipeline (10), and an outlet of the oxygen generation main machine (7) is connected with an oxygen supply mask (9) through an oxygen supply pipeline (11); a shut-off valve (2) is arranged on the engine air entraining channel (14); an outlet of the heat dissipation assembly (3) is provided with a filter (5) and a temperature and pressure sensor (6). And the shut-off valve (2) and the temperature and pressure sensor (6) are in point connection with the oxygen generation controller (1). The reliability and safety of the molecular sieve oxygen supply system can be improved, and high-temperature air is prevented from entering an oxygen generation main machine, damaging a molecular sieve material and scalding crew personnel.
