Abstract

The invention discloses an OBD system-based vehicle data collector and a collecting method thereof, and belongs to the technical field of vehicle-mounted systems. The vehicle data collector comprisesan OBD data collector, and further comprises an MCU driving module, a main scheduling module, a real-time information acquisition module, a communication protocol analysis module, a communication module, a data buffering module and a communication module management module; the MCU driving module is used for providing an operation environment for each module; the main scheduling module is used formonitoring the running condition of each module, issuing a control instruction and coordinating the working states of all the modules; and the real-time information acquisition module is used for controlling the OBD data collector to collect real-time vehicle information of the vehicle, and providing the running state information such as a vehicle bus state, a dormant application and the like to the main scheduling module. According to an OBD-II application layer protocol, the collected vehicle data frames are analyzed, so that the vehicle state data acquisition keeps high efficiency and accuracy under different vehicle platforms.

Description

technical field [0001] The invention belongs to the technical field of vehicle systems, and relates to a vehicle data collector based on an OBD system and a collection method thereof. Background technique [0002] With the continuous development of Internet of Vehicles technology, the popularization and application of intelligent transportation has become one of the important development trends at present. The important features of the Internet of Vehicles include: the collection of vehicle data and the transmission of vehicle data. Among them, an important system for vehicle data collection is an OBD (On-Board Diagnostic System, On-Board Diagnostic System) system. [0003] OBD system is a standard specification for automobile self-diagnosis system proposed by the Society of Automotive Engineers (SAE). Originally mandated by the government to monitor vehicle exhaust emissions, OBD systems monitor multiple systems and components, including engines, catalytic converters, par...
