Description
Technical Field

Background
The vacuum metal pipeline train runs in a metal pipeline close to vacuum, and due to the fact that the train is low in air resistance and friction, the theoretical speed per hour can reach thousands of kilometers per hour, and the vacuum metal pipeline train has the advantages of being high in speed, energy-saving and the like. Such vacuum tube-transported vehicles resemble a "capsule", each "capsule" being placed in a tube and launched like a "cannonball" to a destination.
In the development stage of the high-speed train, the running test of the high-speed train without a person is carried out. In the test process, test data of each important device of the high-speed train needs to be transmitted to a ground command center for scientific research personnel to perform data analysis and emergency decision.
Test data of equipment on a train running at a high speed is transmitted to the ground, and only wireless transmission equipment can be used. Because the pipeline is made of metal materials, electromagnetic waves penetrate through the metal pipeline, and wireless signals received by the terminal are very weak. Electromagnetic waves are transmitted in metal pipes, and due to the refraction and reflection of signals by metal, the transmission distance is short, and is usually in the range of several kilometers.
In order to transmit important experimental data on a high-speed train running in a closed metal space to a ground command center, the patent innovatively provides a design scheme of an information acquisition system for a vacuum metal pipeline high-speed train.
