July 10 news, a few days ago China's first intelligent high-speed train sample car in the South Locomotive Qingdao Sifang Locomotive Co., Ltd. completed off the assembly line. It is learned that the first intelligent high-speed train based on the CRH380AL new-generation high-speed EMU technology platform independently developed by China Sifang Sifang Co., Ltd. is based on the state perception of the holographic train and supported by intelligent information processing for the first time. Of the Internet of Things technology, sensor network technology in large-scale transport equipment engineering applications, as well as the Internet of things, sensor networks, train control network, vehicle transmission network multi-network integration, with self-testing, self-diagnosis, . In addition, intelligent high-speed trains use IoT technology extensively. The main equipment of the train is equipped with electronic tags to record the equipment's factory hours, fault conditions, maintenance history and other historical information and provide information support for the future operation of the train and equipment maintenance. The widespread adoption of IoT technology for smart high-speed trains or the implication of car networking is accelerating.
