Abstract: An adjustment method of an atmos clock and a detection system performing the adjustment method are provided. The adjustment method includes detecting a magnetic field around a balance wheel of the atmos clock via a magnetic sensor, generating a measured signal, receiving the measured signal via a processing unit, and performing a clamping process on the measured signal. A clamping value is subtracted from the measured signal to generate a clamped signal. A zero value line crosses a waveform of the clamped signal to form a zero crossing point in each of the periods of swing motion of the balance wheel. The adjustment method further includes retrieving a time of the zero crossing point, calculating a time difference between the zero crossing points of two adjacent periods, calculating a length of the period according to the calculated time difference, and outputting the calculated length to an output device.

Abstract: A device for monitoring synchronous signals of a motor includes a detection module and a processor. The detection module includes a rotational speed detector and an electric detector. The rotational speed detector is adapted to detect a rotational speed of a motor to generate a rotational speed signal. The electric detector is adapted to detect a current value and a voltage value between the motor and a power supply to generate a current signal and a voltage signal, respectively. The processor is electrically connected to the detection module to receive the rotational speed signal, the current signal, and the voltage signal. The processor generates an analysis result according to instant values of the rotational speed signal, the current signal, and the voltage signal at a same time point. The detection accuracy of the operating status of the motor is, thus, increased.
