Embodiment 1

[0076] A car exhaust detection method based on the combination of Bluetooth and OBD, please refer to the attached figure 1 shown, including:

[0077] S1. Start the detection APP of the smart terminal, connect the detection APP to the vehicle-mounted OBD Bluetooth, and obtain vehicle information through the vehicle-mounted OBD. The vehicle information includes vehicle VIN code, vehicle fault code, vehicle history detection information and mileage information;

[0078] S2, compare the VIN code of the vehicle with the cloud server database, and load the historical detection information in the cloud server database;

[0079] S3. Connect with the exhaust gas analyzer Bluetooth through the detection APP of the smart terminal, and perform appearance detection, oil temperature detection and dual-idle exhaust gas detection in sequence;

[0080] S4. The method of appearance inspection specifically includes:

[0081] The inspection APP of the smart terminal displays the process informa...

Embodiment 2

[0093] On the basis of the detection method provided in embodiment 1, this embodiment also includes:

[0094] When the cloud server database does not contain the VIN code of the vehicle, it is also necessary to enter the vehicle information of the tested vehicle, and the entry methods include:

[0095] Manually input vehicle information;

[0096] Record the driving license.

[0097] This embodiment complements the detection process steps of the new detection vehicle and the secondary detection vehicle. After the secondary detection vehicle compares the vehicle VIN code, it will automatically update the historical detection information from the cloud server database, and the new detection vehicle will enter the vehicle information. , An electronic file will be established in the cloud server database, which is convenient for the owner's event tracing or data query.

Embodiment 3

[0099] On the basis of Embodiment 1 and Embodiment 2, this embodiment provides a vehicle exhaust detection system based on the combination of Bluetooth and OBD. Please refer to the attached figure 2 shown, including:

[0100] The intelligent terminal 101, the vehicle-mounted OBD102 and the exhaust gas analyzer 103; the intelligent terminal 101 is respectively connected with the vehicle-mounted OBD102 and the exhaust gas analyzer 103 through the Bluetooth protocol;

[0101] The intelligent terminal 101 is loaded with a detection APP, and the detection APP is provided with a vehicle information page, an appearance detection page, an oil temperature detection page, a double idle speed detection page and a historical information page; the detection APP can display the detection process and detection results;

[0102] The vehicle-mounted OBD102 can upload vehicle information, vehicle temperature information and vehicle speed information during detection through Bluetooth, and the ...

Abstract

The invention discloses a method and system for detecting automobile exhaust gas based on combination of a Bluetooth and an OBD. The method comprises the steps that: a detection APP of an intelligentterminal is connected with a vehicle OBD and a Bluetooth of an exhaust gas analyzer to obtain vehicle information through the vehicle OBD; the vehicle information is verified; appearance detection, oil temperature detection and two-speed idle exhaust gas detection are executed in order by a detector through the exhaust gas analyzer; a detection result is obtained and uploaded to a cloud server, adetection report is printed, and a maintenance recommendation is fed back. The method and system for detecting automobile exhaust gas based on combination of the Bluetooth and the OBD only need to input vehicle information once to reduce the device quantity and the complex degree on the detection line, achieve cloud information sharing and avoid a complex flow of human paper audit.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust detection, in particular to an automobile exhaust detection method based on the combination of Bluetooth and OBD. Background technique [0002] At present, domestic vehicle exhaust testing includes two parts: vehicle condition performance testing and exhaust emission testing. For light-duty vehicles, most of the exhaust emission detection adopts the dual-idle speed detection method. Vehicle condition performance inspection Check whether the vehicle has mechanical failures, circuit failures, and parts defects. One of the necessary conditions for building an M station), the maintenance is qualified to reach or close to the factory performance; the vehicle exhaust emission detection can accurately judge the environmental protection treatment items required by the vehicle based on the measured exhaust emission data. In this process, the car owner is exhausted, the filling and submission o...
