Electromobile data acquisition and management system based on visual instrument

Abstract

The invention discloses an electromobile data acquisition and management system based on a visual instrument. The system is characterized by comprising a vehicle-mounted data acquisition system and an upper computer data management system, wherein the vehicle-mounted data acquisition system comprises a wireless transmission module, a controller area network (CAN) protocol control module, a CAN bus driving module, a high-speed photoelectric coupler, a secure digital (SD) storage module and a global positioning system (GPS) positioning module; the CAN protocol control module is used for acquiring data on a vehicle-mounted CAN bus in real time and packaging the acquired data; the wireless transmission module is used for sending the acquired data to a digital signal processor of the upper computer data management system; and the upper computer data management system comprises a data transceiving module, a data processing module, a driving operating condition automatic generation module and a driving operating condition on-line identification module. By the system, on-line and real-time identification of the driving operation condition of an automobile is realized, reliable reference is provided for real-time adjustment of an electromobile control policy, and the economy, the dynamic property and the smoothness of fuel oil are further improved.

Description

technical field [0001] The invention relates to a virtual instrument-based electric vehicle data collection and management system. Background technique [0002] With the increasing consumption of non-renewable resources such as petroleum and the general improvement of people's awareness of environmental protection, energy saving and environmental protection have become two major themes in the world today. Under this background, the electric vehicle with the advantages of low fuel consumption, low emission and high benefit has become one of the "hot spots" in the research and application of the automobile industry. By analyzing and processing the driving data in the CAN network of the electric vehicle, the running status of the vehicle can be effectively grasped, and the basis for the optimization of the power system control strategy can be provided. Therefore, it is particularly important to collect, analyze and manage electric vehicle driving data. However, the current ex...
