The embodiment of the invention provides a data transmission system based on the Internet of Vehicles, and belongs to the field of expressways. The system comprises a vehicle-mounted module, at least one roadside module connected to the Internet, a cloud module and a security authentication module, wherein the vehicle-mounted module is used for collecting state information of a vehicle; the roadside module is used for collecting real-time information of road conditions, traffic flow and environment; the security authentication module verifies and manages the identities of the vehicle-mounted module, the road side module and the physical user, and if authentication is passed, the data is encrypted by adopting a Hash algorithm and then transmitted; and the cloud module analyzes the uploaded data according to a preset rule and provides personalized services. The data transmission system based on the Internet of Vehicles realizes real-time data transmission and interaction between the vehicle and the road infrastructure and between the vehicle and the cloud platform through cooperative work of all the modules, and adopts an identity verification mechanism and an encryption technology to ensure the security and confidentiality of the data in the transmission process.
本发明实施例提供一种基于车联网的数据传输系统,属于高速公路领域。该系统包括:车载模块、被连接到互联网的至少一个路侧模块、云端模块以及安全认证模块;其中,车载模块用于收集车辆的状态信息;路侧模块用于收集道路状况、交通流量、环境的实时信息;安全认证模块对车载模块、路侧模块及物理用户的身份进行验证和管理,若通过认证,则采用哈希算法对数据进行加密之后传输;云端模块根据预设的规则对上传的数据进行分析,并提供个性化服务。基于车联网的数据传输系统通过各模块的协同工作,实现了车辆与道路基础设施、云端平台之间的实时数据传输与交互,而且采用身份验证机制和加密技术,确保数据在传输过程中的安全性和保密性。
