摘要
在现场应用过程中,受应用环境变化、电磁干扰、牵引回流等因素的影响,轨道电路参数也会发生变化。因主轨信号电压幅值相对较大,抗干扰能力较强,信号传输较为稳定,小轨信号电压幅值相对较小,易受到上述因素的干扰。通过分析小轨受到干扰后的信号变化,初步提出小轨信号抗干扰性提升的措施。
During on-site application,the parameters of the track circuits may change due to factors such as changes in the application environment,electromagnetic interference,and traction return current.Due to the relatively large voltage amplitude of the main track signals,they exhibit strong anti-interference ability and stable signal transmission.However,the relatively small voltage amplitude of the small track signals is susceptible to interference from the aforementioned factors.This paper analyzes the signal changes of small track circuits after interference and proposes preliminary measures to improve the anti-interference ability of small track signals.
