Abstract: Aiming at the problems of mechanical lock and management mode of high-speed railway gate, this article designed and developed a remote control system of high-speed railway gate based on passive intelligent lock, described the selection of system scheme, overall architecture, composition of software and hardware, basic workflow and system functions. The application results show that the system has the characteristics of simple and convenient application and authorization, stable and reliable operation, which can effectively eliminate the blind area of safety management of high-speed railway gate, and implement the intelligent, network and information management of highspeed railway gate.
