On-board wireless communication device for trains

Abstract

The invention discloses a train on-board wireless communication device, and mainly aims to solve the problem that the network signal is poor, the communication quality is low and the Internet speed is low on trains. The train on-board wireless communication device comprises an antenna (1), a combiner module (2), a power divider module (3), an SIM card module (4), a USB module (5), an ATOMD525 core processor module (6), a SATA hard drive module (7), and a network module (8). The combiner module is connected with the antenna module and the power divider module in a two-way mode. The SIM card module is connected with the power divider module and the USB module in a two-way mode. The ATOMD525 core processor module is connected with the USB module, the SATA hard drive module and the network module in a two-way mode. The SIM card module is loaded with nine SIM cards of three major operators in order to increase the bandwidth. The speed of access to the Internet is improved, uninterrupted communication in the moving state of users is ensured, and the demand of train passengers for Internet access can be met.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a vehicle-mounted wireless communication device, which can be used in wireless network systems of passenger trains such as bullet trains and high-speed rails. Background technique [0002] As a main way for people to travel, the train has billions of passengers every year. As people rely more and more on the Internet, they also need to be able to connect to the Internet when taking the train. People access the network mainly through SIM cards on the train. There are few base stations along the railway line, the network signal is weak, and the speed is slow, which cannot meet people's needs. In order to solve this problem, the existing technology is to use the existing server on the train to provide a wireless local area network, but this method cannot really connect to the Internet, and the communication module of this type of device is relatively simpl...
