英文摘要： Wireless communication environment of mountains and tunnels brings new challenges to the data transmission of multi-locomotive synchronization control system for heavy haul railways. The reliability of the transmission is seriously affected by the coverage blind area, weak field, complex interference. According to this problem, this project plans to research the reliability key technologies of wireless broadband communication in mountains and tunnels. 1800 MHz propagation characteristics and mathematical model will be studied in order to provide theoretical foundation for the key technologies of communication reliability. The weak field coverage optimization method for TD-LTE wireless networks in mountain and tunnel areas will be also studied. The tunnel group of wireless network coverage optimization scheme will be presented. Then the causes and solutions of wireless communication reliability in mountains and tunnels will be mainly discussed. The intelligent handover decision algorithm between double networks will be put forwarded. For the internal and external interference of tunnels, the interference suppression model based on collaborative optimization theory will be built to ensure the real-time and the reliability of synchronous control information wireless transmission between the locomotives.
