Abstract
The invention is based on a vehicle fault detector (decoder ) platform; a Bluetooth terminal can monitor and compare present operation parameters of many cars in real time, an analysis result can be informed to a maintenance technician in a most direct mode, and the technician can fast locate a vehicle fault point through a special selecting mode; vehicle of same model have approximately same operation conditions under same environment, and sensor operation parameters are also similar, so the vehicle fault detector (decoder ) can use data flow reading function to respectively connect with Bluetooth terminals of different cars, thus reading real time sensor parameters of different cars; when a to-be checked (fault) car and a normal car are connected, the fault point of the to-be detected car can be fast located through parameter intelligent comparison analysis, thus greatly improving vehicle fault point locating ability of the vehicle maintenance technician, and helping an automobile 4s shop and a vehicle maintenance factory to improve work efficiency.
Description
Technical field
The present invention builds on vehicle failure detection instrument (demoder) platform, a kind of to be compared by Bluetooth terminal Real-Time Monitoring multi-section vehicle current operating parameter, analysis result is informed Service Technician in mode the most intuitively, and technician can fast locate vehicle failure point by screening anomaly mode.
Background technology
OBDII agreement is a standard agreement of the associated engine exhaust emissions of International Environmental Protection tissue definition, can obtain the exhaust emissions situation of regarding Car engine and basic operation conditions by OBDII agreement.OBDII agreement all supported by the engine of most of vehicle on the market.
Automobile engine system is a typical comprehensive complication system, and from structure, the Mechatronic Systems that it is made up of each subsystems such as mechanical, electrical, liquid, belongs to multilayer hierarchical structure; From fault characteristic, it is complicated etc. that it usually shows as failure symptom complexity, causa relation between fault and fault.
And due to the limitation of fault diagnosis technology and application, current China OBDII vehicle manufacturing detects engine failure and also rests on the manual detection stage, mainly adopt ear to listen to touch the detection method and means that wait backwardness with hand.This mode not only efficiency is low, modern production demand can not be met, and due to the impact of master, objective factor, often easily occur false retrieval, undetected, very large impact is caused on machine product quality, cannot meet the new requirement that modern OBDII vehicle maintenance industry and car owners propose.
Summary of the invention
Utilize " reading data flow " function of vehicle failure detection instrument (demoder), respectively by the Bluetooth terminal being connected to different vehicle, read the real time sensor parameter of different vehicle.Sensing data is beamed back detector main frame by the Bluetooth wireless data transmission technology by advanced person, and vehicle failure detection instrument (main frame) carries out intelligent compare of analysis according to the data passed back, and comparison result is presented to Service Technician.
Obtain running status code from described electric-control system and decoding is based on certain communication protocol, described communication protocol comprise in Class category-B bus protocol, IS014230-2, IS015765-4, IS09141-2 and SAE J1850 one or more.
Embodiment
As shown in Figure 2, long-distance intelligent detection method: diagnosis terminal obtains the current running status code of this vehicle and real time data from the electric-control system of vehicle to be checked, judge according to described running status code the running state of the vehicle comprising vehicle trouble, and can reflect that the information of running state of the vehicle (particularly fault state) is uploaded by wireless network in the form of data.
As shown in Figure 1, upload rear data acquisition character image directly perceived and show, and more easily allow people see fault and the real time data of automobile intuitively.Describedly can reflect that the information of running state of the vehicle (particularly fault state) comprises and represent vehicle operating normal information and characterize the information that vehicle certain or some position there occurs the fault of certain character, these information can be the spoken and written languages forms that the mankind use, also can be its implication by consult the default table of comparisons can the code understood by the mankind.
When connecting (fault) vehicle to be checked and a normal vehicle, namely can the trouble spot of quick position vehicle to be checked through parameter intelligent compare of analysis, high degree improves auto repair technician vehicle failure point capability, and help 4 S auto shop, Automobile Service Factory increase work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, patent of the present invention is further illustrated.
Fig. 1 is main frame schematic diagram.
Fig. 2 is terminal schematic diagram.
