Abstract: In order to solve the problems of time-consuming, low efficiency and error prone existing in the current way of railway operation line construction dispatching command communication, this paper put forward the overall architecture, network architecture and security design for electronic communication system of railway construction dispatching command, and developed the system functions according to the actual needs. The system effectively improved the transmission speed, efficiency and accuracy of dispatching command, reduced the labor intensity of relevant staff, implement the informatization of construction dispatching command, and helped to improve the safety of railway operation line construction.
