Abstract
A power monitoring system is disclosed. The power monitoring system is applied to a communication system having an echo cancellation circuit, an audio processing device and an audio inputting device for controlling the assembling state of the echo cancellation circuit. The system includes a monitoring element electrically coupled to the audio processing device for monitoring whether the audio processing device is electrically coupled to an external audio inputting device and generating a monitoring signal according to the result; a controller for generating an outputting signal in response to the trigger of a monitoring program of the communication system; a power management circuit electrically coupled to the monitoring element and controller for generating a power control signal in response to the trigger of the monitoring signal or the outputting signal; and a switch element electrically coupled to the power management circuit and the echo cancellation circuit for controlling the echo cancellation circuit into a turn off state or a working state in response to the trigger of the power control signal.
