Research on Issues Related to Wireless Route Advance Notice Transmission in CTC System
On the lines equipped with GSM-R,wireless route advance notice is an important function of the centralized traffic control(CTC)system.The accurate transmission of wireless route advance notice is of great significance for efficient,safe and reliable railway transport.By analyzing the application status quo of wireless route advance notice transmission,the factors that may easily cause incorrect wireless route advance notice transmission and the current processing mechanism,this paper focuses on special scenarios such as train number data transmission between different regional groups,repeated train number data and abnormal cancellation of train number data,and combining with 2 actual cases,describes the transmission process of route advance notice in detail,and analyzes the logic of processing by the CTC system to prevent incorrect transmission.Given that there remains a possibility of incorrect wireless route advance notice transmission for repeated train number data under the existing protection mechanism,this paper proposes a scheme for optimization.By integrating the CTC system with the GSM-R system,train operation information can be sent to the train in advance through the wireless route advance notice,which can effectively improve the train operation efficiency,enhance train operation safety and optimize dispatching resources.
