Abstract

In order to prevent and reduce the occurrence of railway safety accidents and solve the problem that construction workers frequently change deceleration signal boards according to train release conditions,.firstly, overall framework and system composition of the intelligent mobile deceleration signal board were constructed according to the railway technical regulations and application business scenarios.. Then, display components of mobile signal board was innovatively designed by using the flap display technology and the intelligent control components of the deceleration signal board were studied by using low-power technology of STM32 microcontroller, high-precision positioning technology of Beidou foundation and mobile communication technology.Finally, an intelligent mobile deceleration signal board management method and remote control system were proposed. The results show that intelligent mobile deceleration signal board can realize the automatic adjustment and remote control of the speed limit display,at the same time, it has the characteristics of portability and low power consumption, meets on-site use and effectively reduces number of operators on the railway during non-skylight hours. © 2019 China Safety Science Journal
