Novel Online Detection System on Optical Performance of Automobile Glasses

With the development of automobile industry, automobile glass type and quantity increased quickly. Automobile glass not only protects the passenger, but also affects the security, appearance of automobile and passenger’s comfort. As a result, optical performance of automobile glass, which is the most parameter, has provoked the attention of manufacturer and consumer. At present, the detection technology on optical performance of automobile glass has played more and more role in industry. In order to improve production efficiency and rate of finished products, a novel on-line detection system was proposed. The system utilized photoelectric technology, weak signal process and SCM technology, can detect the reflectivity and transmissivity on-line. The system was debugged by the Proteus, and the result indicated that the system has strong immunity from interference, and can regulate self-parameters, so as to ensure the reliability and stability.
