摘要
城市轨道交通车辆与地面通信的稳定性和准确性对运营安全至关重要。将LTE(长期演进)技术与WLAN(无线局域网)技术进行比较,分析LTE用于城市轨道交通车-地通信的技术优势。通过对郑州轨道交通1号线一期工程基于LTE技术的车-地无线通信网络系统方案进行分析,并对1号线的通信网络进行实测,验证了LTE技术的可行性。
Stability and accuracy of car/ground communica- tion is essential for the safe operation of urban rail transit. In this paper, LET (long-term evolution) technology is compared with WLAN technology, the advantages of LET technology applied in metro vehicle/ground communication are analyzed. Through an introduction to the communication network of Zhengzhou Metro Line 1 which has used LTE technology, the feasibility of LTE technology applied in urban rail transit is verified.
