1. A turbine fracturing system, comprising:
a turbine engine;
a speed reducer coupled to the turbine engine;
a fracturing pump coupled to the turbine engine via the speed reducer;
a brake mechanism; and
a controller,
wherein:
the turbine engine is configured to drive the fracturing pump to perform a fracturing operation through the speed reducer in an operating state;
the fracturing pump is configured to draw a fluid at a first pressure and discharge the fluid at a second pressure in the operating state, the second pressure being greater than the first pressure; and
the controller is configured to, in response to receiving an operation termination instruction to terminate the operating state of the fracturing pump, generate an idling instruction which triggers the turbine engine to enter an idling state and triggers a brake operation of the brake mechanism to transition the fracturing pump into a non-operating state.
