摘要
民用无线通信广泛应用,严重干扰了轨道交通信号CBTC系统。广州地铁9号线CBTC系统采用的无线跳频技术,解决了无线干扰问题。分析CBTC的无线传输网络,介绍FHSS无线跳频技术在广州地铁9号线的应用。
With the widespread application of civil wireless communication, the Communication Based Train Control system of rail transit is facing seriously disturbances. The CBTC system of Guangzhou subway No. 9 line adopts wireless frequency hopping so as to solve the problems of wireless disturbance. We analyze the wireless transmission network of the CBTC system and in- troduce the application of FHSS wireless frequency hopping in No. 9 line of Guangzhou subway.
