现代有轨电车信标定位系统比较

摘要

分析了现代有轨电车信号控制系统中的绝对定位特点,分析了射频识别技术在不同应用频率波段的特点.对几种常用信标定位系统的车载阅读器和轨旁信标进行了详细比较.由于现代有轨电车存在安装空间小、维护性要求高、成本要求严格等方面的限制,Balogh信标系统在现代有轨电车绝对定位应用中具有更大的优势.%The characteristics of absolute positioning in modern tram control system,the characteristics of radio frequency identification in different frequency bands are analyzed,different kinds of onboard tag readers and the trackside beacons which are applicable for railway industry are separately compared.Due to the limited installation space of modern tram,high maintenance reliability and low cost for the onboard equipment are strictly required,and the Balogh beacon and reader system have the advantage over other devices in modern tram absolute positioning system.
