Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as figure 1 Shown, the PLC control method of the electrogalvanized zinc layer thickness based on BP neural network algorithm of the present invention may further comprise the steps:

[0032] A. Training sample data collection

[0033] Collect a certain number of actual production data samples in the electro-galvanizing production line, about 10,000 samples, and ensure the ergodicity of the data. Samples are collected in the form of input vectors and output vectors. One input vector and one corresponding output vector form a set of sample data. The input vector includes elements such as the thickness of the upper coating, the thickness of the lower coating, the width of the steel strip and the total current of the plating tank; the output vector includes two elements, the calculation speed of the upper coating thickness and the ca...
