摘要 针对仅站内覆盖无线网络条件下的临时限速处理进行研究,在站内有无线网络覆盖条件下,与列车通信,将站内列车走行路径范围的临时限速信息及区间临时限速信息发送给列车,实现列车在区间运行时,在未覆盖无线网络条件下,使用出站前接收到的临时限速信息控制列车安全运行。相比全线覆盖无线网络,或全线设置有源应答器,临时限速研究方式造价更低,适用性更强。 This paper studies the processing of temporary speed restriction under the condition of wireless network coverage only in stations.Under this condition,communication is established with trains to send the following information to the trains:the temporary speed restriction that is applicable to the train's operation path within the station and the temporary speed restriction in the sections.As a result,when trains operate in sections beyond the reach of wireless network coverage,they utilize the temporary speed restriction information received before leaving the station to control the safe operation of the trains.Compared with the method of wireless network covering an entire rail line or the method of setting switchable balises along an entire line,the temporary speed restriction research method in this paper has lower costs and stronger applicability.
