Research on the Application of Domesticated Vehicle-Grade Intelligent Vehicle Gateway Based on Beidou in the Power System

In response to the application requirements of power transmission and distribution inspection and emergency repair vehicles in mobile operation scenarios, a domestically produced vehicle-grade intelligent on-board gateway based on the Beidou system was designed and implemented. This gateway aims for autonomous control and adopts a domestic vehicle-grade dual-core processor (MCU + MPU architecture), a national encryption security chip, and a Beidou multi-frequency module to build a hardware platform. It achieves comprehensive domestic substitution and performance optimization from the chip to the system. The test results show that the positioning accuracy is ≤ 1 m, the communication delay is≤ 50 ms, and the data transmission success rate is ≥ 99.9%. In practical applications, the positioning error converges to 0.8 m, the emergency response time is compressed to 5 s, and the data upload efficiency is increased by 40%. The innovation point of the research lies in the construction of a software and hardware integrated architecture based on domestic chips, breaking the dependence of power mobile operation equipment on imported components; at the same time, multi-source fusion positioning and short message communication are deeply integrated into the vehicle-grade gateway, ensuring the reliable transmission of emergency instructions even in the absence of public network signals.
