Zirconium oxide ceramic nozzle workpiece temperature early warning method

The invention relates to the technical field of data processing, in particular to a zirconia ceramic nozzle workpiece temperature early warning method. According to the method, a production field artificial intelligence system is used for finishing nozzle workpiece temperature early warning. The method comprises the steps that firstly, the temperature, the workpiece feed ratio and sound information of a cut nozzle workpiece are obtained; the temperature uniformity is determined according to the temperature change degree of the nozzle workpiece, and the cracking coefficient of the nozzle workpiece is determined based on the temperature uniformity and the fluctuation degree of the workpiece feeding ratio; the difference distance of different cutting processes is obtained based on the similarity degree of the workpiece feeding ratios, the temperatures and the cracking coefficients of the different cutting processes; calculating an outlier factor based on the difference distance, and calculating a normal sound in
