Mobile terminal commercial vehicle monitoring system for realizing diagnosis technology and Bluetooth communication under Android platform

Abstract

The invention discloses a mobile terminal commercial vehicle monitoring system for realizing a diagnostic technique and Bluetooth communication under an Android platform. The system comprises a commercial vehicle environment, a lower computer and an upper computer, wherein the vehicle environment is provided with an OBD2 (On-Board Diagnostics 2) diagnostic interface which is connected with the lower computer and can be used for transmitting vehicle Can (Controller Area Network) information consistent with a J1939 protocol in the vehicle; the upper computer and the lower computer can communicate with each other through a Bluetooth module; the lower computer further comprises an OBD2 diagnostic interface male end plug, a power supply module, a CAN receiving-transmitting module, a storage module and the Bluetooth module; the power supply module is connected with a control unit, the storage module, the CAN receiving-transmitting module and the Bluetooth module; the upper computer is an Android mobile terminal. The system acquires real-time state data of the vehicle from the vehicle diagnostic interface, and the vehicle is monitored and managed through the Android mobile terminal. The system has the advantages of low cost, convenience, rapidness, high reliability, high portability, freeness from wiring, reduction of failure points and low requirement on technical personnel.

Description

technical field [0001] The invention belongs to the technical field of wireless network communication, and in particular relates to a mobile terminal commercial vehicle monitoring system based on Android platform diagnosis technology and Bluetooth communication. Background technique [0002] The common OBD2-16-pin diagnostic socket (OBD is the abbreviation of On-BoardDiagnostics, Chinese translation is "on-board self-diagnostic system"), which is mainly used for vehicle detection during vehicle maintenance, can collect vehicle information through this interface. Status information for each component. ODB2, a new ODB standard introduced in the 1990s, provides nearly complete engine control and monitors the chassis, body and auxiliary equipment, as well as the car's diagnostic control network. Currently, there are five main communication protocols used by ODB: ISO, KWP, PWM, VPW, and CAN. [0003] At present, there is a driving recorder for real-time monitoring of the status...

AI Technical Summary

Problems solved by technology

[0003] At present, there is a driving recorder for real-time monitoring of the status of various components of the vehicle. Most of these devices are connected to the vehicle components to collect the vehicle status by modifying the vehicle wiring. , Especially for commercial vehicles, the vehicle data monitored at the same time is limited, which may also affect the after-sales service of the vehicle
