摘要:
针对城市轨道交通地面高架区域敷设波导管、隧道区域敷设自由波的无线组网方案在高架段发生无线同频干扰的问题，提出了通信信号一体化的无线通信系统抗干扰性能提升方案。即基于自由波和波导管有机融合的车地信息传输,通过高精度的定位配合电子开关切换来提升抗干扰性能。通过实验室和现场试验验证了所提出抗干扰解决方案的有效性，并在北京地铁某线大规模推广应用，可为基于无线局域网的CBTC车地无线通信系统抗干扰性能提升作参考。
Abstracts:
Targeting the problem of wireless co\|frequency interference of wireless network system that lays waveguide in urban rail transit ground elevated area and free wave in tunnel area, a scheme to improve the anti\|interference performance of wireless communication system integrating communication and signal is proposed. That is, the vehicle\|wayside information transmission based on the organic integration of free wave and waveguide, improving anti\|interference performance through high\|precision positioning and electronic switch controlling. The effectiveness of the proposed anti\|interference solution is verified by laboratory and on\|site experiments and is widely applied on certain line of Beijing Metro, providing reference for improving the anti\|interference performance of CBTC vehicle\|wayside wireless communication system based on WLAN.
