    • PURPOSE: A rotation detector for a water drain pump and a control method thereof are provided to improve rotation detection accuracy of the drainage pump. CONSTITUTION: A rotation detector for a water drain pump comprises a drainage pump(20), an optical sensor(30), a controller(40) and an alert potion(50). A blocking guide is installed on the water supply pump in order to block the optical line and is rotated by the motor. The optical sensor is installed around the drainage pump. The optical sensor generates and outputs pulse according to the optical line blocking of the guide. The controller counts the signal inputted from the optical sensor for fixed hour and outputs control signal. If the controller senses that the pulse is not input more than a definite number, outputs control signals according that the drainage pump is not rotated. The alert potion outputs warning signal according to the control signal of the controller.
    • 目的:提供一种排水泵的旋转检测器及其控制方法,以提高排水泵的旋转检测精度。 构成:用于排水泵的旋转检测器包括排水泵(20),光学传感器(30),控制器(40)和警戒药液(50)。 在供水泵上安装有阻挡导向件,以阻挡光线并由电机旋转。 光学传感器安装在排水泵周围。 光学传感器根据导光板的光线阻挡产生并输出脉冲。 控制器对固定时间光传感器输入的信号进行计数,并输出控制信号。 如果控制器检测到脉冲输入不是一个明确的数字,则按照排水泵不旋转输出控制信号。 警报药液根据控制器的控制信号输出警告信号。
