Many industries have begun to use optical brighteners, such as paper, plastics, leather, and detergents. At the same time, fluorescent whitening agents are also used in many high-tech fields, such as fluorescence detection, dye lasers, anti-counterfeiting printing, etc., and even high-sensitivity films for high-altitude photography. In order to improve the sensitivity of photosensitive latexes, fluorescence is also used. Brightener.

In China, optical brighteners were first classified as printing and dyeing auxiliary products, and then classified as dye products. Due to its unique properties and large amount of demand, it has been separated from the above two industries and has become a separate class of fine chemical products. The first largest user of domestic fluorescent whitening agents is detergents, the second largest user is paper, and textiles are the third largest user.
Yihe Institute obtained three national software works authorization
[ China Instrument Network Instrument R&D ] The instrument and network control center of the IHG is based on the development of the horizontal project "Industrial Control System Equipment Condition Monitoring Tool Software" based on three industrial Ethernet protocols: OPC UA, Profinet, ModbusTCP. In-depth analysis, through the joint efforts of Zhao Yanling, Han Dantao, Gong Yanjie engineers, etc., developed "Industrial Ethernet OPC UA Security Monitoring Software", "Industrial Ethernet Profinet Security Monitoring Software", "Industrial Ethernet ModbusTCP Security Monitoring Software" Three security monitoring softwares have been licensed by three national software works.
Industrial control system field device communication is gradually transitioning from a closed fieldbus to an open industrial Ethernet, while efficient and standardized system integration has become an important part of industrial control systems. As a new generation of integration standards introduced by the OPC Foundation, OPC UA will play an increasingly important role in the horizontal integration between devices and devices in industrial control systems and in the vertical integration of industrial Internet data. As a typical industrial Ethernet protocol, Profinet and Modbus TCP have a large number of applications in the industrial field. Therefore, information security attacks against devices supporting these protocols may lead to the impact of industrial control systems and production safety.
The security monitoring software developed for the three major industrial Ethernet protocols OPC UA, Profinet and Modbus TCP realizes deep analysis of packets, data filtering and operation monitoring based on process configuration information. According to the user-defined security configuration policy, unauthorized access of unauthorized devices can be prevented, network status can be monitored in real time, key write operation data of three protocols can be monitored in real time, and alarm information can be displayed in real time. The tool software has no impact on the normal industrial control network. The configuration strategy can effectively protect the key equipment and protect the security of the industrial control network. Therefore, the software has a wide range of application fields and market promotion prospects.
