Description

technical field [0001] The invention relates to a differential frequency multiplication rotary encoder used for distance detection and direction identification of construction machinery and hoisting equipment. Background technique [0002] In the field of construction machinery, existing sensing technologies mostly use potentiometers and encoders to detect distances. The potentiometer method mainly uses a mechanical stroke limiter plus a potentiometer for measurement. The rotation of the worm drives the rotation of the potentiometer, so that the voltage changes. Calculate the distance of each mechanism according to the voltage for limit control. In practical applications, this technology has some problems that must be solved. The mechanical worm gear itself has processing errors, and the potentiometer is a contact type, which cannot rotate freely for multiple turns and has a certain service life. Therefore, this method of distance measurement The precision is not enough. ...
