The cable length metering device is a common device in the cable production process and is mainly used for length metering devices of conductor, insulation, cabling and other procedures. More importantly, the finished products are delivered by taking the rice mark on the outer sheath of the cable as the final length unit accepted by the client. However, in the actual meter counting process, the number of bits of the counter is usually 6, the number of bits of the decimal point is also fixed, when the number of bits exceeds the number of bits of the decimal point, the counter cannot be identified and cannot be used for metering, the counter is accumulated based on a counting signal sent by the encoder, for example, based on the diameter of the wire wheel:
when the diameter is 0.3 m, the diameter,
number of counter bits: 6 bits, 2 bits of decimal place,
if the circumference of the wire wheel in the encoder is 0.94, 10000 turns are 9400.00 m,
if the circumference of the yarn guide wheel in the encoder is taken as 0.942, only meters to 1000 meters, namely 940.000, the length use requirement is not met when the long-distance segment length superposition is calculated, namely the existing device records that the yarn guide wheel rotates by integral multiple of one circle, and the circumference of the yarn guide wheel can only take a little bit less if the measuring distance is long, so that a great error occurs after the number of turns is increased, and the circumference takes more bits if the measuring distance is accurate, so that the measured length is reduced, and the daily production requirement cannot be met.
