Embodiment Construction

[0017] figure 1 It is a schematic diagram of an embodiment of the vehicle data analysis system of the present invention. Such as figure 1 As shown, the vehicle data analysis system of this embodiment mainly includes two parts: a vehicle data acquisition module and a mobile terminal device. Wherein, the vehicle-mounted data acquisition module includes a core processor, a non-volatile memory module, and a Bluetooth low-power module that supports Bluetooth protocol version 4.0 or above. The core processor of the on-board data acquisition module can collect and process vehicle-related data in real time through the vehicle's on-board diagnostic system interface. The Bluetooth wireless connection between the mobile terminal device and the Bluetooth low-power module of the vehicle-mounted data acquisition module includes two states: connection and disconnection. Relevant data is stored in the non-volatile storage module. When connected, the vehicle-mounted data acquisition module ...

Abstract

The invention belongs to the technical field of vehicle inspection, and particularly relates to a vehicle data analysis system. The vehicle data analysis system comprises a vehicle-mounted data collecting module and mobile terminal equipment. The vehicle-mounted data collecting module comprises a core processor, a non-volatile storage module, a Bluetooth low-power-consumption module supporting a 4.0 or higher version, and the core processor can collect and process data related to vehicles in real time through an interface of a vehicle-mounted diagnostic system for the vehicles. Bluetooth wireless connection between the mobile terminal equipment and the Bluetooth low-power-consumption module can be in a connected state or a disconnected state, when the Bluetooth wireless connection is in the disconnected state, the vehicle-mounted data collecting module will store the data which are collected and processed by the core processor in real time and related to the vehicles in the non-volatile storage module, and when the Bluetooth wireless connection is in the connected state, the vehicle-mounted data collecting module will transmit the data which are collected and processed by the core processor in real time and related to the vehicles to the mobile terminal equipment in real time and transmit the data which are related to the vehicles and stored in the non-volatile storage module to the mobile terminal equipment.

Description

technical field [0001] The invention relates to a vehicle data collection and transmission system, in particular to a vehicle data analysis system, which belongs to the technical field of vehicle detection. Background technique [0002] The function of On Board Diagnostic (OBD) is to detect the operating parameters of each system of the car and read the running data of the vehicle. Initially, its purpose is mainly to detect the exhaust emission of the car to meet the requirements of environmental protection. With the development of technology, the current application of OBD has far exceeded the simple environmental protection detection and expanded to the detection of various sensors in the whole vehicle and the access to the on-board computer. After the system is started, it will enter the engine, gearbox and other systems to read fault codes and other sensor data through the on-board computer, and finally access data with external devices through the standard OBD interface...
