Abstract

The invention discloses a method for accurately measuring the cable winding and unwinding length and a synchronous controller. Setting of external following speed is acquired by the controller in real time, automatic logic control, manual logic control and the like of a system are achieved according to a control button and a selective switch, and information of winding and unwinding speed, control states and the like is displayed on a display unit; a winding radius signal formed by a cable is acquired in real time through a designed winding radius measurement device; pre-designed counting teeth of a winding reel and a proximity switch form a winding turn number signal; the two signals form corresponding digital quantity signals through an embedded controller, and cable winding speed is calculated on the basis of the cosine law of a triangle and additional operation; the calculated cable winding speed and the external set following speed are subjected to PID operation, then, the controller controls the output of a driver through the digital quantity signals and an analog quantity signal interface, the driver controls the running speed of a motor, and the motor drags the cable winding reel to achieve consistency between the winding speed and the external given speed.

Description

technical field [0001] The invention relates to a method for accurately measuring the retractable length of a cable and a synchronous controller. Background technique [0002] The cable is wound during the cable production process or in some emergency lighting situations. Sometimes it is necessary to accurately measure the length of the coiled cable and control the winding speed. Since the radius formed by the cable on the cable reel is constantly changing during the cable winding process, it is difficult to accurately measure the winding length. In the case of emergency lighting, the mobile device is used to wind the cable, and the winding speed is required to be consistent with the speed of the mobile device. The above-mentioned length measurement and synchronous winding with the mobile device are difficult to obtain high accuracy only by manual work, so an automatic device is needed. Contents of the invention [0003] In order to solve the above problems, the present...
