Turnout warning system

The utility model discloses a turnout warning system which is used for sensing the relative position of an outer rail and an inner rail, an unthreaded hole is formed in the middle of the outer rail in the thickness direction of the outer rail, the turnout warning system comprises two sensing assemblies, and the two sensing assemblies are arranged in the unthreaded hole. The two sensing assemblies are arranged at the unthreaded holes of the tracks on the two sides of the outer track respectively. The installation position of the sensing assembly is located at the position relatively close to the end of the inner rail, so that the sensing assembly is driven to sense the position where the end of the inner rail is located when the inner rail approaches the outer rail. According to the turnout warning system, the sensing assembly is adopted to detect the combination position of the inner rails, the detection precision is high, the warning effect can be achieved after the rails are not combined, meanwhile, directi
