With tire manufacturing enterprises leveraging smart factories, they have broken through the traditional production mode of tire companies, adopting advanced technologies such as information communication, digital control, and intelligent equipment to gradually achieve the matching of people, materials, equipment, and location information. The character verification system is a kind of detection equipment in the tire production process, primarily used to improve the efficiency and accuracy of tire surface information processing, which is of great significance. This article proposes the concept, composition, and working principle of the character verification system device from multiple aspects such as the definition, classification, coding, and application of characters in tires. At the same time, it analyzes the practical application advantages and effects of this system in the tire production process. Through this system, the efficiency of management and production has been effectively improved, and human errors have been significantly reduced. However, there are also many problems in the use of this system that need further optimization and improvement to make it more intelligent.
