Abstract Currently, the safety of the railway operation mainly depends on ground devices; however, the security and reliability of railway operation face serious challenges. When the ground signals and wireless communication devices are severely damaged, the use of traditional GPS satellite positioning combined with terrestrial wireless communications technology is a solution to ensure safety. However, GPS has no communication function so that in the case of extreme natural disasters the information cannot be fed back to the control center, so it still cannot meet the requirements. Beidou satellite navigation system has a short message communication function that meets the demand to send messages. The auxiliary control system from railway operation safety based on Beidou intelligent navigation services is proposed. The system is consisted of vehicle intelligent terminal subsystem and train smart location-based services platform subsystem. The vehicle intelligent terminal subsystem achieves real-time positioning through Beidou, also obtains the train-running information that will be sent to the ground subsystem by short message, such as speed, kilometer mark, front and rear-train distance and so on. The train smart location-based services platform subsystem dynamically monitors the train’s running status after receiving the running information and makes right dispatch so as to ensure the railway operation safe. Thus, the system plays an important role in securing the safety of railway operation and distress rescue aids decision-making.
