摘　　要：阐述高速铁路应答器轨道区段信息包报文发送方式,并对实际场景中存在的特殊情况进行分析。对于无直股接发车进路的车站和线路所,区间应答器报文中轨道区段数据仅描述至进站信号机处,此场景下存在部分动车组越过进站信号机后会触发制动;当出站信号机内外方存在上下行载频切换时,动车组在部分监控模式下缓慢运行,导致解码延时后掉码;动车所内采用25Hz轨道电路叠加列控编码,正线及股道有码,当股道未设置出站应答器组,办理发车进路,动车组选择股道下行载频后,在发车进路信号机接近区段存在与股道不同的载频,如果不提前手动切换载频会造成动车组列车触发制动。针对以上出现动车组制动的3种特殊场景,提出相应的解决方案,为工程设计、列控数据编制提供借鉴。The paper discusses the telegram transmission method of track section information packets of high-speed railway balises and analyzes the special situations in practical scenarios.For a station or block post without straight train receiving/departure routes,the track section data in the section balise telegram only describes the situation to the home signal and some EMUs may brake after crossing the home signal.When uplink and downlink carrier frequency switching inside and outside the starting signal,the EMUs run slowly in the partial supervision mode,resulting in code dropping after decoding delay.The EMU depots adopt a 25 Hz track circuit to superimpose train control codes and there are codes on the main line and tracks.When the tracks are not equipped with a starting balise group to handle departure routes,a carrier frequency different from that of the track exists in the approach section of the departure route signal after the EMU selects the downlink carrier frequency of the track.Failure to manually switch carrier frequency in advance will cause the EMU to brake.In view of the above three special scenarios of EMU braking,corresponding solutions are proposed as reference for engineering design and train control data compilation.
