A method and device for determining the location of an access point

Abstract

The invention provides a method and device for determining the position of an access point, and the method comprises the steps: obtaining signal intensities detected by a plurality of network signal detection devices in a preset access point signal coverage at the same time; obtaining the distances from the network signal detection devices to a preset access point according to the signal intensities; constructing a plurality of spherical surfaces according to the distances, and obtaining the connection lines among intersection points of the plurality of spherical surfaces; obtaining detected signal intensities at the same time after the network signal detection devices moves along the connection lines; and determining the position of the preset access point according to the detected signal intensities after the network signal detection devices moves along the connection lines. The method carries out two-time simultaneous obtaining of the signal intensities of the preset access point through the plurality of network signal detection device, so as to determine the position of the access point. The method achieves the quick and accurate positioning of the access point, gets rid of the limits from the inaccurate description of marks and files of construction drawings, is less in positioning time, and improves work efficiency.

Description

technical field [0001] The invention relates to the field of wireless technology, in particular to a method and device for determining the location of an access point. Background technique [0002] At present, when the WLAN network is constructed, the access point AP is generally placed on the ceiling, cable wells and other hidden places. Sometimes only the feeder is drawn from the radio frequency port to connect to the external antenna. When the AP fails and needs to be replaced or repaired Sometimes, it is necessary to accurately find the physical location of the AP. Generally, when building a WLAN network, the relevant construction drawings or documents are marked or the physical location is briefly described. When it is necessary to find the location of the AP, the location of the AP is found on the actual site according to the drawings and documents. [0003] In addition, the location of the AP can be determined by using the triangulation method of scanning the signal ...

Problems solved by technology

[0008] The method of using construction drawing annotations and document descriptions can generally only indicate the approximate physical location of the AP, which is not accurate. When the physical environment changes, sometimes it takes time and effort to find it. If the AP has been replaced or repaired, or the WLAN network After the upgrade, the physical location of the AP has changed, but the relevant drawings or documents have not been updated in time, so it will take more time and effort to accurately find the physical location of the AP, which is extremely inefficient and very unfavorable to WLAN network maintenance.

[0009] The disadvantage of the triangulation method using a directional antenna to scan signal strength is that it requires a special directional antenna, rotates the antenna to determine the center of the strongest signal, and needs to move at least 2 times to scan the signal strength at least 3 points, this method It takes a lot of time to scan the signal strength and move, and the efficiency is low, and only the position of the AP on the two-dimensional plane (XY axis plane) can be determined, and the specific position of the AP in the three-dimensional space (Z axis) cannot be determined. The location needs to be manually searched on site. Although this method avoids the unfavorable factors caused by the untimely update of documents and gets rid of the restrictions of construction drawings, the time efficiency is low and the positioning is not accurate enough.
