    摘要： Railway detection system for detecting the presence of a railway vehicle on a railway track section comprising at least two rails, the railway track section comprising a first end and a second end opposite to the first end in a longitudinal direction of the railway track section, the railway detection system comprising a track circuit system comprising a signal generator electrically coupled to the first end of the railway track section, the signal generator being configured for generating a first track circuit signal to be injected into the railway track section at the first end, wherein the signal generator is adapted to



    generate a first component of the first track circuit signal comprising at least one DC pulse;
    generate a second component of the first track circuit signal, and
    add the first and the second component so as to obtain the first track circuit signal.

    摘要： An active fixed block track circuit comprises at least a fixed block section, comprising at least two rails corresponding to each other, each having an isolation connector at two ends thereof and connected to a power supply unit and a traffic signal; a short driving unit, connected to each of the two rails within the fixed block section; and a detection unit, connected to the short driving unit. In this manner, not only the previous rail traffic signal circuit function where no more than one train may be allowed into the same fixed block section is maintained, but also another train approaching from the rear may be prevented from entering the fixed block section when the detection unit at the fixed block section detects an exceptional case happening at a neighboring fixed block section so that the traffic signal unit is switched into a stop traffic signal.

    摘要翻译： 主动固定块轨迹电路至少包括固定块部分，其包括彼此对应的至少两个轨道，每个轨道的两端具有隔离连接器，并连接到电源单元和交通信号灯; 短的驱动单元，连接到固定块部分内的两个轨道中的每一个; 以及连接到短驱动单元的检测单元。 以这种方式，不仅可以保持先前的轨道交通信号电路功能，其中不超过一列可以被允许进入相同的固定块部分，而且当从后方接近的另一列可以防止进入固定块部分 在固定块部分的检测单元检测在相邻固定块部分发生的异常情况，使得交通信号单元被切换成停止交通信号。
