F5G industrial optical ring network communication technology and its application and prospect in coal mines
Abstract
The traditional wired communication network in coal mines has problems such as fixed bandwidth, low effective utilization, high time-delay, and inflexible system configuration. This cannot meet the development needs of intelligent business in coal mines. Mining 5G and WiFi6 wireless communication has the problem of large roadway attenuation and lower reliability than wired communication. According to the characteristics of F5G (the fifth generation fixed networks) industrial optical ring network communication technology, it is pointed out that F5G industrial optical ring network communication technology is the development trend of mine wired communication. Two key technologies of F5G industrial optical ring network are introduced. They are 10 Gibit/s PON (passive optical network) technology and digital quick optical distribution network (DQ ODN) technology. The advantages of F5G industrial optical ring network and traditional wired network in network delay, electrical safety, business safety, construction safety and maintenance safety are compared. Based on the demand characteristics and construction examples of F5G industrial optical ring network communication technology applied in coal mines, this paper analyzes the specific applications of F5G industrial optical ring network communication technology in scenarios such as underground industrial remote control, high-definition video transmission, industrial network migration, remote fault diagnosis, and wireless network signal transmission. It points out the shortcomings and prospects of F5G industrial optical ring network communication technology in coal mines. ① There are few types of mining equipment based on F5G industrial optical ring network communication technology. ② There is still room for improvement in the adaptation of scenarios and different business types. ③ The F5G industrial optical ring network communication technology is the same as the traditional Ethernet ring network communication interface in terms of system interface and protocol. The terminal equipment can be accessed and used without changing the adaptation. It is an effective solution for the industrial network in the future coal mine scenario. ④ Coal mines should build F5G pilot projects based on their own actual conditions to support the application and research of F5G industrial optical ring network communication technology with actual scenarios.
