Abstract

The invention discloses a low-power intelligent onboard diagnostic device and method capable of automatically switching off. The device comprises an MCU microcontroller for data analysis, control and a remote upgrade function and a group connected with the MCU microcontroller and including a power supply module, a display module, a key module, a sensor module, a vehicle bus module, a vehicle positioning module, and a host computer module. The power supply module is composed of a main power supply module and a backup power supply module, and powers the onboard diagnostic device. The sensor module obtains the G-sensor information of the vehicle and transmits the information to the MCU microcontroller. The device and method solve large power consumption and incapability of switching off power supply in the prior art.

Description

technical field [0001] The invention belongs to the technical field of on-board diagnosis, and in particular relates to an intelligent on-board diagnosis device with low power consumption that can be automatically disconnected. Background technique [0002] With the continuous development of automobile industry technology, automobiles have become an indispensable means of transportation in people's daily life. Connect the OBD (On-Board-Diagnostics, on-board automatic diagnosis system) intelligent on-board diagnostic device to the car, and the user can quickly obtain useful information such as vehicle information and driving conditions from the OBD terminal. At present, most of the on-board diagnostic devices are powered by the car battery. If the power consumption of the on-board diagnostic device is too large, when the power loss of the battery reaches a lower limit threshold, the on-board diagnostic device and the warning cannot be automatically disconnected. Long-term use...
