Hose fatigue automatic test system capable of automatically shielding failed hose

The invention discloses a hose fatigue automatic test system capable of automatically shielding failed hoses. The hose fatigue automatic test system capable of automatically shielding the failed hosesis characterized in that the hose fatigue automatic test system comprises a supercharger, a main stop valve, multiple first shunt stop valves and second shunt stop valves, a pressure sensor, an unloading exhaust valve and a controller; an outlet of the supercharge is connected with an inlet of a main stop valve; an outlet of the main stop valve is respectively connected with inlets of the first shunt stop valves, and outlets of the second shunt stop valves are respectively connected to the unloading exhaust valve; hoses are connected between outlets of the first shunt stop valves and inlets of the second shunt stop valves; the pressure sensor can conduct real-time acquisition of pressure data at the outlet of the main stop valve; when tests begin, the controller starts the supercharger, closes unloading exhaust v
