[0003] At present, in the tire industry, when producing tire semi-product on the extrusion line equipment such as the tread, the sidewall and the inner liner, many production lines still adjust the process parameters by the experience of the host machine itself during production, and do not set the process parameters according to the construction standard. In addition, the process standard is not updated in time, so that the production experience of the operator is particularly important in the production process. With the same production time, the production quantity of the experienced operator is more and the quality is good, and the production quantity of the operator lacking experience is less and the quality is general. There are unstable production and uneven quality, which cannot meet the production plan and need to frequently adjust the production plan. In addition, the product quality in the production process is checked by the operator manually or by quality inspection, and there is an error in manual measurement. Once the measurement is inaccurate, a batch of quality accidents will occur, which will cause economic losses to the company when discovered. In addition, if it is not checked out, it will be released to the market, which is incalculable to the brand image and economic losses of the company.
