It introduces the Train Control and Monitoring System of the urban rail vehicle and the existing buildings and layout of a certain urban rail depot, and then analyzes the data transmission requirements of Train-Ground Wireless Transmission System. And then it designs the system scheme, including the selection of wireless module installation location, system topology, equipment selection and detailed parameters. Also, it 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 the data transmission requirements, and the implementation of the project has an important guiding significance for the existing urban rail depot.
