An Information Collection and Transmission Strategy of Vehicle State-Aware System Based on OBD Technology and Android Mobile Terminals

To provide the Traffic Regulatory Authority with detailed driving status of vehicles when an accident occurs, this paper proposes an information collection and transmission strategy based on OBD technology and Android mobile terminals. This strategy records the representative detailed operation parameters and location information of traveling vehicles. It removes the drawbacks of server load existing in the conventional vehicle state-aware systems, due to collect and upload the data in real-time. At last, we achieve a highly efficient transmission process by compressing the uploaded data.
