Problems solved by technology

Due to various factors such as collisions, signal attenuation, and noise interference caused by the same-frequency transceiver competition for shared wireless channels, the network frequency resource consumption of network nodes each time receiving and forwarding information will reduce the overall transmission bandwidth capacity of the loss network.
Caused a sharp convergence of up to 40% of the network transmission bandwidth; seriously affected the broadband multimedia information transmission communication performance of the network

Abstract

The invention discloses a wireless local area network transmission node device for an underground power station and a signal transmission method. The network transmission node device comprises: an antenna group module, a network function module, a state display module, a power module and a box body. The network function module is connected with the antenna group module and is used for comparing the intensity of the handshake transmission carrier signal in the dual-channel carrier signals received by the antenna group module, storing multimedia data carried by the handshake transmission carriersignal with the highest signal intensity, converging the multimedia data to a peripheral network in a pilot frequency mode, and sending the dual-channel carrier signal to the network node unit with the optimal bandwidth capacity. Optimization of a wireless local area network transmission routing link of the underground power station is realized by determining the intensity of a dual-channel carrier signal and the bandwidth capacity of a network node unit, and meanwhile, low convergence rate of a network transmission bandwidth is realized by adopting dual-channel carrier round-robin receivingand transmitting.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless local area network transmission node device and method for an underground power station. Background technique [0002] In the high-bandwidth multimedia local area network of underground power stations, the network node is the basic unit of the local area network, which is responsible for the broadband bidirectional transmission of multimedia information in the local area network. At present, the relevant local area network basically adopts the same-frequency relay forwarding mechanism. Due to various factors such as collisions, signal attenuation, and noise interference caused by the same-frequency transceiver competition for shared wireless channels, the network frequency resource consumption of network nodes each time receiving and forwarding information will reduce the overall transmission bandwidth capacity of the loss network. It causes a sharp convergence of more than ...
