Spinning machine laser yarn monitoring system

The utility model belongs to the technical field of spinning machine monitoring equipment, and particularly relates to a spinning machine laser yarn monitoring system which comprises a controller body, a laser transmitter, a laser receiver and an audible and visual alarm, and the controller body is electrically connected with the laser transmitter, the laser receiver and the audible and visual alarm through wires. The laser transmitter is electrically connected with the modulator through a wire, the modulator is electrically connected with the encoder through a wire, the laser receiver is electrically connected with the decoder through a wire, and the decoder is electrically connected with the data recognition circuit through a wire. The encoder and the decoder are arranged and matched with the modulator, the data identification circuit, the synchronous circuit and the execution circuit, so that debugging alignment is simpler and more convenient, debugging-free and maintenance-free effects can be basically re
