Abstract

The utility model discloses an automobile multimedia network intelligent embedded type fault diagnosis device which is simple in structure and can rapidly and accurately perform automobile fault diagnosis. The automobile multimedia network intelligent embedded type fault diagnosis device is used for diagnosing and parsing a fault code of a fault vehicle. The fault vehicle is internally provided with a driving computer. A fault acquisition unit is inserted into the driving computer of the fault vehicle via a data line. The fault acquisition unit is connected with an MCU in a controlling way. The MCU comprises a fault code storage device which stores the fault code of the vehicle and corresponding fault information of the fault code. The MCU sends the fault code and the parsed vehicle fault to a displayer. The MCU is also connected with a maintenance database server via a wireless communication unit. Further, the fault vehicle is an experiment table simulating the fault vehicle. Further, the wireless communication unit is a WIFI module, a bluetooth module, or an infrared communication module.

Description

Car multimedia network intelligence embedded failure diagnosis apparatus

Technical field

The utility model relates to automotive diagnostic unit, is specifically applied to the diagnosis of vehicle failure.

Background technology

Along with the develop rapidly of auto industry, be applied to electronic control system on automobile also more and more, yet due to the electronization of automobile, brought difficulty to the quick diagnosis of vehicle failure; Traditional automotive diagnostic unit, accurately the system general structure of quick diagnosis fault is complicated, and cost is high; Fault diagnosis system simple in structure often can not be confirmed fault again fast and accurately.

Summary of the invention

Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of simple in structure, and can carry out fast and accurately the car multimedia network intelligence embedded failure diagnosis apparatus of automobile failure diagnosis.

The utility model solves the technical scheme that its technical matters adopts: car multimedia network intelligence embedded failure diagnosis apparatus, for diagnosing and the diagnostic trouble code of resolve fault vehicle; In described fault vehicle, car running computer is installed, fault collection unit is plugged on the car running computer of fault vehicle by data line, fault collection unit controls is connected to MCU, and MCU comprises the diagnostic trouble code reservoir that stores vehicle trouble code and the corresponding failure message of diagnostic trouble code; MCU is sent to display by diagnostic trouble code and the vehicle trouble that parses;

Described MCU is also connected to mantenance data storehouse server by radio communication unit.

Further: above-mentioned fault vehicle is the experiment table of simulated failure vehicle.

Further: above-mentioned radio communication unit is WIFI module, bluetooth module or infrared communication module.

The utility model compared with prior art has the following advantages:

The utility model car multimedia network intelligence embedded failure diagnosis apparatus, is connected to MCU(microprocessor by fault collection unit), MCU has diagnostic trouble code and corresponding failure message thereof by memory stores; The diagnostic trouble code that therefore can the very first time fault collection unit be collected is resolved, and diagnostic trouble code is communicated with to the failure message being resolved to and is passed to display; Realized whole fault diagnosis quick and precisely; In addition, by MCU, by the failure message of diagnostic trouble code and parsing being further sent to the further contrast that mantenance data server carries out failure message, can guarantee that final failure message is accurately resolved.

Accompanying drawing explanation

Fig. 1 is structured flowchart of the present utility model.

Embodiment

Below in conjunction with drawings and Examples, the utility model embodiment is described:

Fig. 1 shows a kind of concrete structure of the related cotton-wadded quilt body of the utility model, and as shown in the figure, car multimedia network intelligence embedded failure diagnosis apparatus, for diagnosing the also diagnostic trouble code of resolve fault vehicle; In described fault vehicle, car running computer is installed, it is characterized in that: fault collection unit is plugged on the car running computer of fault vehicle by data line, fault collection unit controls is connected to MCU, and MCU comprises the diagnostic trouble code reservoir that stores vehicle trouble code and the corresponding failure message of diagnostic trouble code; MCU is sent to display by diagnostic trouble code and the vehicle trouble that parses;

Described MCU is also connected to mantenance data storehouse server by radio communication unit.

Above-mentioned fault vehicle is the experiment table of simulated failure vehicle, and thus, the utility model can be for teaching or slip-stick artist's training.

Further, above-mentioned radio communication unit is WIFI module, bluetooth module or infrared communication module.

By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.

Do not depart from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
