Problems solved by technology

At this time, the traditional solution is to forcibly shut down all APs or let all APs continue to work, but forcibly shutting down all APs will affect the few people who are still working, and making all APs continue to work will lead to energy waste

Embodiment Construction

[0023] The present invention provides a set of technical proposals to self-adaptively shut down the AP power supply or the radio frequency function. Such as figure 2 As shown, in the case of high load (daytime), all APs work to provide the maximum access bandwidth, and in the case of low load (night, rest day), if the energy-saving control node detects that there is no user access to AP node B, and When the reverse neighbors A, E, and C of B are online, the AP node B can be shut down, and at the same time, the power of the AP nodes A, E, and C can be adaptively increased to cover the area covered by the original AP node B. If the energy saving control node detects that the load of AP node E is greater than a given threshold, and detects that B in the reverse neighbor of AP node E is turned off by energy saving, it will turn on AP node B and adjust the power of the neighbors of node B to reduce the RF interference due to the addition of Node Bs.

Abstract

The invention discloses a WLAN equipment self-adaptive energy-saving method. The method comprises the steps of periodically maintaining neighbor information and load information of an AP (Access Point), and calculating the reverse neighbor number; periodically inspecting the load of the AP in the condition that coverage is satisfied, and self-adaptively closing the AP without user load; simultaneously covering signal black holes caused by the closing of the current AP by selfadaptively increasing the power of peripheral neighbor APs; periodically inspecting the load of the AP in the condition that coverage is satisfied, self-adaptively opening the AP closed for saving energy if the load exceeds a set threshold value, so as to improve the access performance; simultaneously reducing radio-frequency interference caused by the increasing of the AP by self-adaptively reducing the power of the peripheral neighbor APs. The method adjusts relevant AP power by self-adaptively closing part of AP power supplies or radio frequency functions in the condition that coverage is satisfied, and achieves the purpose of saving energy and reducing emission to the hilt.

Description

technical field [0001] The invention relates to a technical solution in the field of environmental protection and energy saving, in particular to a method for controlling energy waste [0002] fee-based technical solutions. Background technique [0003] Because it can provide high-speed wireless connection services, WLAN (Wireless Local Access Network, wireless local area network) is one of the more popular technologies in the IT (Information Technology, information technology) industry at present, and it is also a popular wireless access method. A WLAN usually adopts a centralized AC (Access Controller, wireless controller)-AP (Access Point, wireless access point) architecture. The AC provides centralized management of the WLAN network, and the AP establishes a link with the AC to join the WLAN network and provides wireless access services. [0004] Since entering the 21st century, the awareness of energy conservation, environmental protection and environmental protection...
