The rapid development of plastic optical fiber automatic control technology

With the rapid development of computers and automatic control technology, the level of industrial automation has reached a new level. Industrial automation can be divided into process control automation, automation for production and manufacturing, and automated measurement systems (industrial measuring instruments) according to its characteristics and directions of use. The establishment and development of these industrial automation systems have a common feature, that is, the development of a direct control system to a distributed control system, and the development of this distributed control system is based on various industrial networks. Through these various industrial bus systems, various industrial equipment forms a decentralized and unified whole. For POF, the industrial control bus system is one of its most stable and largest markets. Through the converter, POF can be connected with standard protocol interfaces such as RS232, RS422, 100Mbps Ethernet, token network, etc., thereby providing a stable and reliable communication line in the harsh industrial manufacturing environment, and high-speed transmission of industrial control signals and instructions, avoiding There is a danger of communication interruption due to electromagnetic interference caused by the use of all cable lines.
