计轴设备及无绝缘轨道电路(JTC)作为比较成熟的列车占用检测技术,在铁路及轨道交通中已被广泛应用。通过对两者系统的构成、工作原理的介绍,对比分析了各自在列车占用检测中的特点。 As a relatively mature train occupancy detection technology, axle counting equipment and uninsulated track circuit (JTC) have been widely used in railway and rail transit. Through the introduction of the composition and working principle of the two systems, the characteristics of their occupancy detection in train are compared and analyzed.
