Quick plug type bus local area network communication adapter and implementation method thereof

Abstract

The invention provides a quick plug-in bus local area network communication adapter, which comprises a shell, a power supply and a bus mother board, one or more bus network plug-in card adapter boards are arranged in the shell, the plug-in card adapter boards are connected with the bus mother board through direct plug-in card slots, and the anti-interference of signals between the boards and the control of the bus power supply can be realized; the adapter further comprises: a network signal convergence card insertion board which is used for convergence of a plurality of groups of card insertion adapter boards and optical communication signals; and an optical fiber communication card insertion board which is used for transmitting and receiving optical port network signals. Gigabit-level high-speed network data communication is realized through an extensible bus network structure, a reliable safe voltage power supply is provided for a plurality of network equipments, and the expandability and maintainability of communication paths are effectively improved. According to the method, the application bottleneck of the bus local area network technology is broken through, and obstacles are eliminated for large-scale application of the bus local area network technology.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a fast plug-in bus local area network communication adapter and a realization method thereof. Background technique [0002] Usually, a LAN communication device (such as a switch or a gateway) is equipped with an integral circuit board in the housing, and a data input interface and a data output interface are set on the circuit board. The data input interface is connected to a network terminal device (such as a network camera), and the data The output interface is connected with the terminal equipment to output and display the data. In this network connection method, all network connection points correspond to each other between ports, the connection line is long, and the construction is difficult. The patent number (CN201720505227.0) provides a bus-based LAN communication system, which connects multiple network terminal devices in parallel on one bus, which is similar to t...

AI Technical Summary

Problems solved by technology

[0003] 1. The mutual interference between multiple lines is serious, and the system cannot operate normally;

[0004] 2. It is not conducive to large-scale application, inconvenient system maintenance, and difficult expansion;

[0005] 3. Multi-channel equipment is gathered without effective heat dissipation device, causing serious heating of the main circuit of the equipment, reducing reliability and life;

[0006] Due to the existence of the above problems, it has seriously hindered the popularization and application of bus local area network technology.
