The invention discloses a throttle electrical control system and method. The throttle electrical control system comprises a pressure detection unit, a temperature detection unit, a motor module, a central control unit and a remote control center; the pressure detection unit is connected with a signal conditioning unit, and collects and sends downhole pressure wave signals; the temperature detection unit adopts a temperature sensor, and is used for collecting downhole temperature information; the motor module comprises a motor driving unit, a motor coding unit and a motor system, and the motordriving unit and the motor coding unit send a driving signal and a coding signal to the motor system to control the rotating speed of a motor; the central control unit is connected with an analog-digital converter through an IO interface, receives the pressure wave signals transmitted by the analog-digital converter, awakens a central controller, generates a decoding command, and awakens the motorand the temperature sensor through the decoding command to execute throttle valve control operation; and the remote control center is connected with the central control unit through a wireless module, controls a working mode of the system and conducts temperature compensation. The structure is simple, mounting and maintenance are convenient, and work of a throttle can be conveniently controlled.
