A car intelligent diagnosis and positioning device based on obd-ii interface

Abstract

The invention belongs to the technical field of automobile control, and is specifically an automobile intelligent diagnosis and positioning device based on an OBD-II interface, including a housing, a monitoring device, a socket assembly and electrical equipment. equipment, the monitoring equipment includes a circuit board two, a circuit board one is arranged on the top of the circuit board two, the circuit board two is fixedly installed on the inner wall of the housing, and a USB connector is fixedly installed on one side of the top of the circuit board two, the present invention The beneficial effect is: the intelligent diagnosis and positioning device is connected to the 0OBD-II interface of the car through the OBD-II connector to monitor the real-time dynamics of the car. A monitoring and early warning module is designed in the car intelligent diagnosis and positioning device. When a fault occurs, the monitoring and early warning module gives feedback Early warning, and through the communication module, send information to remind the user that some parameters are abnormal, and at the same time remind the user to deal with it in time through the display module, which has the effect of obtaining OBD‑II interface data and realizing real-time collection and positioning of vehicle data.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an intelligent automobile diagnosis and positioning device based on an OBD-II interface. Background technique [0002] The rapid increase in vehicle penetration has also brought enormous pressure to the vehicle after-sales service industry and breakdown maintenance industry. With the application of electronic technology in vehicles, its safety, power, flexibility and artificial intelligence have been greatly improved. But at the same time, there are many types of vehicle failures, trivial and difficult to detect, so effective diagnosis and maintenance are necessary conditions for the long-term development of the vehicle industry. [0003] The prior art has the following deficiencies: the existing OBD interface detection device usually installs detection software through a computer, connects the equipment signal output terminal to the computer through the USB interface,...

Problems solved by technology

[0003] The prior art has the following deficiencies: the existing OBD interface detection device usually installs detection software through a computer, connects the equipment signal output terminal to the computer through the USB interface, and connects the equipment input terminal to the automobile through the automobile OBD interface. Carry out information detection to discover the working status of auto parts. This information exchange method is relatively cumbersome and requires manual operation to actively read the information. When a car fails, it often misses the best maintenance time because it does not actively detect and locate. , may cause driving hazards
