Problems solved by technology

[0004] Secondly, the layout of indoor power lines, the existence of air switches and the interference of other high-power electrical equipment all hinder the development of power line transmission technology
According to literature, random, synchronous periodic pulse noise is 10-40dB higher than background noise, therefore, the use of external general power equipment or high-power electrical equipment will affect the transmission performance of power line carrier
[0005] Moreover, the use of power line carrier technology in the same network segment will reduce the overall number of nodes in the Mesh wireless sensor network and the connectivity of the network. Therefore, the simple sharing of these two technologies will reduce users' willingness to purchase and build wireless transmission LAN equipment, further Reduce overall wireless network throughput and stability

Abstract

The invention provides a track power supply comprising a pure low-voltage power line carrier transmission network. The track power supply comprises a filter; a PLC module, wherein the PLC module is connected to the filter; and the power supply module is connected between the filter and the PLC module. According to the invention, a closed track power supply is used, a filter network is additionally arranged at the part, connected with an external circuit, of the track power supply, and a closed internal circuit is formed by matching with a filter network in a pluggable matched socket. According to the invention, the overall throughput and stability of the wireless network are improved, and the influence of the use of external circuit equipment or high-power electric equipment on the carrier transmission performance of the power line is reduced.

Description

technical field [0001] The invention relates to the field of track power supply, more specifically, relates to a track power supply including a pure low-voltage power line carrier transmission network. Background technique [0002] As a local area network solution, the power line carrier and its information transmission technology (Power Line Communication, PLC for short) have been developed for decades. [0003] First of all, there are various complex loads connected to the power line, and these loads and the power line itself form many resonant circuits, forming a low impedance area at the resonant frequency and its nearby frequencies. Generally, the impedance of the power line changes dynamically from 20Ω to 190Ω. [0004] Secondly, the layout of indoor power lines, the existence of air switches, and the interference of other high-power electrical equipment all hinder the development of power line transmission technology. According to literature, random, synchronous per...
