Vehicle Positioning Monitoring System Based on GPS/BDS Dual-mode Positioning Technology

With the rise of the IoT and autonomous driving as significant technological innovations and development trends, the design of vehicle positioning monitoring systems has become increasingly crucial in the field of intelligent transportation systems. Simultaneously, their popularity and practicality have integrated them into the daily lives of the general public. However, the majority of vehicle positioning monitoring systems currently available on the market employ single-positioning systems. Addressing these issues, this paper proposes the utilization of GPS/BDS dual-mode positioning technology, providing high positioning accuracy while mitigating certain risks. The paper introduces a three-tier architecture comprising the vehicle-side positioning layer, cloud-side transmission layer, and user-side application layer. Communication among these layers is facilitated through the MQTT communication transmission protocol. This system enables users to monitor real-time vehicle positioning information and save travel records through the application layer device. Through the actual test on urban roads, the vehicle positioning monitoring system designed in this paper performs well in terms of positioning accuracy and data integrity rate, and has certain advantages in terms of popularity and ease of use.
