The invention provides a circular points and a working method thereof. The circular points comprises a rotating rail assembly for driving a trolley to rotate and positioning the predetermined position, a drive motor assembly for driving the rotating rail assembly to rotate, a connecting rail for positioning the rotating rail assembly, an inducing positioning device for inducing the position of thetrolley on the rotating rail assembly, and a rotating supporting device connected with the drive motor assembly and the rotating rail assembly. The circular points belongs to a logistics transmissionsystem of the intelligent rail trolley, the invention makes a breakthrough on the basis of an original linear points, and adopts the combination way of circular and rotary points, the running track of the trolley can be changed in the key node, the whole running network of the trolley is better improved, the operation is noiseless, and compared with a traditional trolley, the friction noise generated by turning is greatly optimized; and the convenient, efficient and stable way of the circular transition device solves the logistics transportation problem, and the circular points can be widelyused in the intelligent rail trolley logistics transmission system.
