Abstract: This paper introduces the current situation of the point heating system of high-speed railways, and introduces the composition of equipment, operation modes and functions of RD1 electric point heating system in detail. In view of the development of new technology of high-speed railways, domestic and international market demands and the development of the technology of the point heating products themselves, it is necessary to overcome the problem of high power consumption and the manual operations based on weather conditions as the only way to boot the systems. The paper focuses on the scheme of an intelligent point heating system which is based on weather stations and train route information. In comparison with  the traditional electric point heating systems (RD1), the intelligent scheme is automatic, efficient, energy-saving with lower consumption, and has friendly man-machine interfaces.
