Example Embodiment

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.

[0026] For each AP, multiple channels can be supported. The AP selects one channel from the multiple channels as the working channel. The working channel is a channel used by the AP for data transmission, and the working channel can be preset.

[0027] For example, the channels supported by the AP can include channels numbered 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 149, 153, 157, 161, and 165. The AP can select 36 channels as the working channel .

Abstract

The embodiment of the invention provides a data sending method and apparatus, applied to a vehicle-mounted AP. The data sending method comprises the following steps: starting full channel scanning after it is determined that a vehicle where the vehicle-mounted AP is located is in a garage, and determining a scanned trackside AP with the best signal quality on all channels supported by the vehicle-mounted AP as a target trackside AP; switching the current working channel to the working channel of the target trackside AP, and establishing a Mesh connection with the target trackside AP; and sending data to the target trackside AP through the Mesh connection. By adoption of the technical solution provided by the embodiment of the invention, the working channels of two adjacent trackside APs are different, thereby reducing the Same frequency interference and improving the throughput of a wireless network. In addition, for the vehicle-mounted AP, one vehicle-mounted AP is connected to one trackside AP, and different vehicle-mounted APs are connected to different trackside APs, and different working channels are used for transmitting data to the trackside APs, thereby reducing the consumption of air interface resources, and further improving the throughput of the wireless network.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data sending method and device. Background technique [0002] In order to facilitate the user to understand the situation of the train during operation and ensure the safety of the train, during the operation of the train, the monitoring camera on the train continuously shoots the scene inside the train. When the train returns to the garage, the monitoring camera on the train sends image data to the on-board AP (Access Point, access point) on the train. Through the Mesh (grid) connection established between the on-board AP and the preset trackside AP in the garage, the on-board AP sends the image data to the trackside AP. The trackside AP sends the image data to the ground server. In this way, the user can understand the situation of the train during operation through the image data received by the ground server, and timely discover and eliminate potentia...
