This study introduces the train control and monitoring system of an urban rail vehicle and the existing buildings and layout of a certain urban rail depot, and then analyzes the data transmission requirements of the train–ground wireless transmission system. The system scheme is then designed, including the selection of the wireless module installation location, system topology, equipment selection, and detailed parameters. It also describes the installation, wiring, and debugging of field equipment, and tests the signal intensity and data communication, which verifies and confirms the effectiveness of the designed system. The application results show that the designed train-ground wireless transmission system meets data transmission requirements, and the implementation of the project has an important guiding significance for existing urban rail depots.
