Channel configuration method, vehicle-mounted AP, detection equipment and wireless communication system

Abstract

The embodiment of the invention provides a channel configuration method, a vehicle-mounted AP, detection equipment and a wireless communication system, and relates to the technical field of communication. The method is used for configuring a channel of the vehicle-mounted AP, and ensuring stability of a wireless communication link built by the vehicle-mounted AP and a track AP. The method is applied to the vehicle-mounted wireless access point (AP), and comprises the steps of receiving a detection signal sent by the detection equipment, wherein the detection signal carries identification information of a preset channel; judging whether signal strength of the detection signal is more than a signal strength threshold; and if yes, configuring the channel to be the preset channel according tothe identification information of the preset channel, and returning a channel switching confirmation message back to the detection equipment. The method provided by the embodiment of the invention isapplied to configuring the channel of the vehicle-mounted AP.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a channel configuration method, a vehicle-mounted wireless access point (AccessPoint, AP), a detection device and a wireless communication system. Background technique [0002] Since information interaction in the mobile state has become an indispensable and important part of people's lives, the realization of wireless communication in rail transit such as trains, subways, and bullet trains has become an increasingly strong demand. [0003] In order to realize the wireless communication of rail transit, the prior art proposes a dual backup link wireless communication system suitable for rail transit. refer to figure 1 As shown, the wireless communication system includes: vehicle-mounted AP1 and AP2 respectively arranged at both ends of the train, multiple track AP3s that can send and receive detection signals along the first extending direction of the track, and mu...

Problems solved by technology

However, in some cases such as figure 1 As shown in 200, the train is running on a loop on the track. When the train travels from station B to station A, the direction of the train changes. At this time, it is necessary to establish a wireless communication link between AP1 and AP4, and establish a wireless communication link between AP2 and AP3. , however, the channel configuration of the vehicle AP and the track AP is still configured as the first channel for AP1 and AP3, and the second channel for AP2 and AP4. Since the channels configured by AP1 and AP4 are different, and the channels configured by AP2 and AP3 are also different, so The wireless link established between AP1 and AP4 is very unstable, or even unable to establish a connection, and the wireless link established between AP2 and AP3 is also very unstable, or even unable to establish a connection
