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.
