A method of using circuit waveform to drive clockwise and counterclockwise movement of quartz watch

Abstract

The invention relates to a method for driving hands of a quartz watch to move clockwise and anticlockwise by means of a circuit waveform. The method comprises the steps that the driving waveform driving the quartz watch to rotate is output through two output ends OUT1 and OUT2; when the quartz watch rotates clockwise, the output end OUT1 outputs a pulse with a voltage amplitude of +1.5 V and a pulse width of 5.9 ms firstly; when the quartz watch rotates anticlockwise, the output end OUT1 outputs a pulse with a voltage amplitude of +0.8-+1.0 V and a pulse width of 0.2 ms firstly, then outputs a pulse with a voltage amplitude of +1.5 V and a pulse width of 0.2 ms 0.4 ms later, outputs a pulse with a voltage amplitude of -1.5 V and a pulse width of 4.9 ms, and finally outputs a pulse with a voltage amplitude of +1.5 V and a pulse width of 5.9 ms in the opposite direction. By the adoption of the driving waveform, a movement of the quartz watch can move clockwise and anticlockwise, so that both clockwise movement and anticlockwise movement can be achieved according to functional requirements.

Description

technical field [0001] The invention relates to a method for clockwise and counterclockwise movement of a quartz watch, in particular to a method for driving the clockwise and counterclockwise movement of a quartz watch by using a circuit waveform. Background technique [0002] At present, the quartz watch movement can only output one-way clockwise driving waveform, and cannot realize the clockwise and counterclockwise rotation of the hands, that is, the hour, minute and second hands cannot realize the clockwise and counterclockwise movement according to the functional requirements. The existing quartz watch movement comprises a control circuit, a stepping motor, and a transmission wheel train formed by various transmission gears. The control circuit drives the stepper motor to rotate, the stepper motor drives the transmission wheel train, and the transmission wheel train drives the hour hand, minute hand and second hand to rotate. [0003] refer to figure 1 , the stator p...
