The invention relates to the technical field of rail safety detection, in particular to a safety detection method for rail transit in a tunnel, safety detection is carried out through a detection system, a rail comprises a first rail body and a second rail body, and the detection system is installed between the first rail body and the second rail body. The specific detection steps of the detection system are as follows: determining a reference point; constructing a datum line; and forming a detection point. The fixing part is pre-buried underground, and a reference point is formed through the fixing part, so that the stability of the reference point is ensured; besides, in the whole detection process, the variable quantity between the detection point and the reference point is reflected by utilizing mechanical change, the mechanical change can be detected without the aid of an image technology, and more importantly, a distance sensor, an angle sensor and the like are utilized, so that the influence of relatively dark light on a detection result is avoided.
本发明涉及轨道安全检测技术领域,具体地说,涉及一种隧道内轨道交通用安全检测方法,其通过检测系进行安全检测,所述轨道包括第一轨体和第二轨体,所述检测系安装于第一轨体和第二轨体之间,所述检测系的具体检测步骤如下:确定基准点;构建基准线;形成检测点。本发明中固定部预埋在地下,并通过固定部形成基准点,从而保证基准点的稳定性;另外,整个检测过程都是利用机械变化来体现检测点与基准点之间的变化量,而机械变化无需借助图像技术实现检测,更多的是利用距离传感器以及角度传感器等,进而避免光线较暗对检测结果造成影响。
