Abstract

The embodiment of the present invention provides a message processing method and device, the method includes: constructing a message, the message is a message of a preset key type that the vehicle-mounted AP needs to build on its own data link layer constructed at the time, or obtained after marking the message to be forwarded when the message attribute of the message to be forwarded in the upper layer of the data link layer is a preset key attribute, and the message contains Presetting the key mark; sending the message to the trackside AP, so that when the trackside AP detects that the message received by itself contains the preset key mark, it sends the message or the The data information carried in the above message is sent to the designated server for trackside AP abnormal location. In the embodiment of the present invention, the designated server can obtain the dynamic switching record of the whole train line according to the content transmitted by the trackside AP, so as to facilitate the positioning of abnormal trackside APs.

Description

Technical field[0001]The present invention relates to the field of communication technology, in particular to a message processing method and device.Background technique[0002]The wireless mesh (Mesh) network can be applied to trains such as subways and high-speed trains. Such asfigure 1 As shown, the wireless Mesh technology can achievefigure 1 The train network shown. Such asfigure 1 As shown, a vehicle-mounted AP is deployed in the carriage, and multiple trackside APs are deployed beside the track, such as trackside AP1, trackside AP2, and trackside AP3.[0003]During the train movement, the vehicle-mounted AP can establish a Mesh connection with the trackside AP to realize train control or provide applications such as monitoring and video. At any time, the vehicle-mounted AP will establish a Mesh connection with a trackside AP. Such asfigure 1 In the network shown, the vehicle-mounted AP currently establishes a Mesh connection with the trackside AP1; when the train travels for a ce...
