The intelligent control panel comprises a wire sensor signal input isolation circuit, a wire cutter signal output isolation circuit, a light emitting diode (LED) signal output isolation circuit, a code dialing circuit, a singlechip work power supply conversion circuit, a level conversion circuit, a singlechip, a singlechip peripheral circuit and a doffing signal isolation circuit, wherein the singlechip periphery circuit is also connected with the wire sensor signal input isolation circuit and the wire cutter signal output isolation circuit, and the intelligent control panel has the advantages that the control is accurate, the anti-jamming capability is high, the data is not easy to get lost, and the like.

Description

technical field [0001] The invention relates to a control panel, in particular to a control panel used for the detection and cutting circuit of a high-speed elastic yarn machine. Background technique [0002] Most of the various high-speed elastic yarn machines in textile machinery adopt the mode of PLC, wire sensor, shredder plate, fixed length plate, and shredder to realize the control of fixed length, fixed weight and broken yarn during the spinning process. Cut off the raw material feed to protect the machine. That is: according to the level change of the wire sensor (for example, from 24V to 0V), the wire cutter stops outputting, the spindle position of the machine starts production, the fixed-length board collects the production signal, and the PLC inquires the signal change through communication. According to the machine The set process parameters are calculated to add a certain length (or weight); when the wire breaks in the middle, the level of the wire sensor chan...

Problems solved by technology

This traditional mode is generally used in various high-speed stretch yarn machines, but with the rise of various textile technologies such as ply yarns, this traditional control method can no longer play a good role in controlling the plying of multi-ply yarns.

Moreover, due to the use of an RS485 communication bus, the control board lacks anti-interference ability in harsh applications. During use, due to damage to a certain fixed-length board, it will interfere with the fixed-length and fixed-weight statistics of the entire machine, and even miscut wires. It affects the production efficiency of high-speed elastic yarn machine
