Wireless looped network communication device and system

Abstract

The invention relates to a wireless looped network communication device and system, the wireless looped network communication device comprises two or more management equipment side switches, and the management equipment side switches are used for forming a management side looped network with switches accessing management equipment. The device further comprises one or more terminal side looped networks, each terminal side looped network comprises three or more terminal side switches forming the looped network, the management equipment side switch is used for being connected with the terminal side switches in one terminal side looped network in a one-to-one correspondence mode, and the terminal side switches are further used for being connected with terminal equipment. Based on this, through the composition of one or more than one terminal side looped network and the cooperation of the management equipment side switch, a plurality of communication links are provided between the terminal equipment and the management equipment, the problems of safety and reliability in a star-shaped or chain wireless local area network networking mode are avoided, and the communication quality and stability are ensured.

Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to a wireless ring network communication device and system. Background technique [0002] In the construction of wireless local area network, the landing measures generally adopt WAPI (Wireless LAN Authentication and Privacy Infrastructure, wireless LAN authentication and privacy infrastructure) solution. WAPI is a security protocol, and compared with the Wi-Fi (Wireless Fidelity, wireless fidelity) protocol formulated earlier, WAPI has higher security. For example, in China Southern Power Grid's promotion of substation wireless local area network construction, WAPI solutions are adopted to adapt to new services represented by robot inspections, visualized operations, or online monitoring of substation status. These new services generally present a large Due to the characteristics of bandwidth, mobility, and large connections, wired communication methods cannot...

Problems solved by technology

For example, in China Southern Power Grid's promotion of substation wireless local area network construction, WAPI solutions are adopted to adapt to new services represented by robot inspections, visualized operations, or online monitoring of substation status. These new services generally present a large Due to the characteristics of bandwidth, mobility, and large connections, wired communication methods cannot meet business needs

[0003] However, the application scenarios where the WAPI solution is implemented are generally greatly affected by the environment, such as large changes in outdoor temperature and humidity, strong electromagnetic field interference, or external damage such as small animals and rats. The wireless LAN networking method adopts star or chain Due to the influence of the environment, security and reliability problems will occur, which will affect the quality and stability of wireless communication
