The invention provides an intelligent hot air anti-icing system based on required anti-icing air-entraining flow and relates to the technical field of aircraft hot air anti-icing system design. The intelligent hot air anti-icing system is used for conducting intelligent dynamic control over and adjustment on the anti-icing air-entraining flow of an aircraft hot air anti-icing system. An atmospheric liquid water content tester arranged at the back of an aircraft measures the liquid water content in the external atmosphere in real time. Anti-icing temperature sensors and anti-icing pressure sensors arranged on anti-icing air-entraining pipes measure the anti-icing air-entraining temperature value and pressure value of aircraft air source supply in real time respectively. An anti-icing flow control device adjusts and controls the opening of electric valves so that the actual air-entraining pressure value of the electric valves and the required air-entraining pressure value can be the same. The intelligent hot air anti-icing system based on required anti-icing air-entraining flow can guarantee the anti-icing performance while greatly saving the air-entraining flow of the aircraft, and influences on engine thrust of the aircraft are avoided.
