针对加载冗余车载设备时列车底部安装空间有限的问题，分别对冷备、热备冗余天线与应答器传输模块BTM天线间的最小安装距离进行研究。利用FEKO软件建立单个BTM 天线、安装冷备冗余BTM 天线、安装热备冗余BTM天线3种模型。研究冷备、热备冗余天线在不同安装距离条件时BTM 天线的有效作用范围，找出冗余天线对BTM天线有效作用范围产生影响的临界点，即冷备、热备冗余BTM 天线的最小安装距离。研究结果表明，冷备冗余天线的最小安装距离为1.12 m ，热备冗余天线的最小安装距离为3 m。冗余BTM天线最小安装距离研究压缩了冗余车载设备在列车底部的占用空间，提高了其在机车上安装的灵活性。

Aiming at the issue of limited installation space at the bottom of a train w hen a standby on‐board de‐vice is installed ,the minimum installation distances from a hot standby Balise Transmission Module(BTM) an‐tenna and a cold standby BTM antenna to a BTM antenna are respectively studied . Three models , a single BTM antenna model ,a cold standby BTM antenna model ,and a hot standby BTM antenna model ,are estab‐lished by using the FEKO software . This paper has respectively calculated the corresponding effective ranges of the BTM antenna when the cold or hot standby antenna is installed under different distance conditions , to find the critical positions of the standby antennas w here the standby antennas have hardly any influence on the effective range of the BTM antenna . In other words , the minimum installation distances between standby an‐tennas and the BTM antenna are found . The results show that the minimum installation distance between the cold standby antenna and the BTM antenna is 1.12 m . The minimum installation distance between the hot standby antenna and the BTM antenna is 3 m . This study on minimum installation distance of standby BTM antennas helps reduce the room occupied by standby on‐board device and improves the flexibility of its installa‐tion in the locomotive .
