    • A system is described that provides redundant communication at a railway crossing. The system comprises a first communication unit (eg. 202) for transmitting information associated with a railway vehicle (208) approaching or near the railway crossing on a railway track. A first active warning sign (206) located at or near the railway crossing receives and transmits information associated with the railway crossing. The system includes an onboard equipment unit (101) located on a roadway vehicle (402) approaching or near the railway crossing, the onboard equipment unit comprising a second communication unit (112) for receiving information from the first communication unit and the active warning sign; a processor (108) for processing the received information to determine a first threat indicator indicative of a potential collision, and a user interface (106) for communicating the threat indicator to a user. The system may include sensors (202,204) to detect and communicate the presence of a train.
    • 描述了在铁路路口提供冗余通信的系统。 该系统包括第一通信单元(例如202),用于发送与在铁路轨道上接近或靠近铁路路口的铁路车辆(208)相关联的信息。 位于铁路过境处或附近的第一个主动警告标志(206)接收和传送与铁路道口有关的信息。 该系统包括位于接近或靠近铁路道口的道路车辆(402)上的车载设备单元(101),该车载设备单元包括用于从第一通信单元接收信息的第二通信单元(112)和主动警告标志 ; 处理器(108),用于处理所接收的信息以确定指示潜在冲突的第一威胁指示符,以及用于将威胁指示符传送给用户的用户界面(106)。 该系统可以包括用于检测和通信列车的存在的传感器(202,204)。

    • To identify an object (2) which emits structure-borne noise onto a base, for example a railway vehicle approaching a track construction site, the vibrations (S) generated by the structure-borne noise are detected by a structure-borne noise recorder (2) attached to a rail (1) and are processed by an evaluation circuit (C). A warning signal (Sw) is emitted when the intensity of the output signal (Sa) from the recorder constantly increases, for example when the intensity exceeds given threshold values in a suitable frequency range in predetermined times; in other words, constantly swelling noise propagated in the rails (1) is evaluated as a reliable criterion for emitting a warning signal that indicates an approaching train.
    • 为了识别将结构噪声发射到基座(例如接近轨道施工现场的铁路车辆)的物体(2),由结构噪声记录器检测由结构噪声产生的振动(S) 2)连接到轨道(1),并由评估电路(C)处理。 当来自记录器的输出信号(Sa)的强度持续增加时,例如当强度在预定时间内在合适的频率范围内超过给定阈值时,发出警告信号(Sw) 换句话说,在轨道(1)中传播的不断膨胀的噪声被评估为用于发出指示接近列车的警告信号的可靠标准。
