The invention relates to a beacon near-end interference prevention device, which comprises a metal box cover and a metal box bottom plate, and is characterized in that two first through holes are formed in two ends of the metal box cover respectively; second through holes corresponding to the first through holes are formed in two ends of the bottom plate of the metal box; the metal box cover is fixed to the metal box bottom plate in the mode that a plurality of bolts penetrate through the first through holes and the second through holes respectively. The invention also discloses an anti-interference method based on the device for preventing the beacon near-end interference. The method comprises the following steps: S1, designing a specific interference device according to the transmitting power of the vehicle-mounted equipment and the distance between adjacent station tracks; s2, installing an interference device; s3, when the train runs to the position above the beacon, a vehicle-mounted RF reader-writer needing to be powered by a power source outputs a wireless radio frequency carrier signal through an external antenna; and S4, the beacon senses the wireless radio frequency carrier signal to obtain energy, activates the beacon and reflects the pre-written position. Beacon lateral radio frequency carrier signals are shielded with low cost, and the beacons are prevented from being activated by crosstalk.

    本发明涉及一种防止信标近端干扰装置,包括:金属箱盒盖和金属箱盒底板,金属箱盒盖两端分别开设有两个第一通孔;金属箱盒底板两端与第一通孔对应处开设有第二通孔;金属箱盒盖通过多个螺栓分别穿过第一通孔和第二通孔固定在金属箱盒底板上。还公开了一种基于防止信标近端干扰装置的防干扰方法,包括:步骤S1,根据车载设备发射功率和相邻股道的间距设计特定的干扰装置;步骤S2,安装干扰装置;步骤S3,列车运行至信标上方时,需要通过电源供电的车载RF读写器通过外接天线输出无线射频载波信号;步骤S4,信标感应到无线射频载波信号获得能量,激活信标并反射预先写入的位置。用较低的成本实现屏蔽信标侧向射频载波信号,避免信标被串扰激活。
