Design and Implementation of an Intelligent Monitoring System for Um Interface Based on Software Radio

Aiming at the shortcomings of cumbersome code writing and poor flexibility in traditional system design methods, this paper designs a wireless signal intelligent detection system based on software radio. The modular system design method is adopted to reduce the complexity of the design. Through the test on the high-speed comprehensive detection train, it is verified that the system can monitor the interaction process between the on-board equipment and the GSM-R network base station in real time, and realize the closed-loop monitoring of the vehicle-to-ground data transmission process. The receiving part and analysis part of the system can be connected through the network, and the flexibility of system deployment is increased by 7.3%.
