Industrial-grade optical transmission system

Abstract

The invention discloses an industrial-grade optical transmission system, belonging to the field of power communication. In the industrial-grade optical transmission system, optical transmission equipment also comprises a main interface module and a standby interface module facing to optical terminal equipment, wherein the main interface module is a wired interface module, and the standby interface module is a wireless interface module; the wired interface module is used for wired connection with optical network equipment; the wireless interface module is used for wireless connection with a main station side; and when a main interface fails in data transmission, a standby interface is started by a configuration with external network management. According to the industrial-grade optical transmission system, the synchronization of networks is realized, convergence, transparent transmission and exchange are carried out on different data, the safety of information transmission is enhanced, the main-standby switching function of an optical network and a wireless network is realized, the transmission of important data is ensured and the reliability of the networks is improved.

Description

[0001] technical field [0002] The invention relates to the field of industrial control, especially the field of power communication, and realizes reliable and real-time transmission of information between power terminal equipment and master station equipment. [0003] Background technique [0004] At present, the industrial control network needs to realize long-distance information transmission. For example, the power communication system needs to realize the information transmission between the power information terminal and the central master station within tens of kilometers or hundreds of kilometers. These information transmissions require communication networks to be highly real-time, reliable, manageable, and maintainable. For this reason, the Ethernet passive optical network (EPON) is usually used to realize the information access under the condition of no electric relay. However, the EPON network cannot meet the requirements of numerous terminal nodes, complex inf...
