Description
Technical field
The utility model relates to a kind of vehicle failure reminiscences.
Background technique
The development of automobile at present is that the industry of leaning on is propped up in the economic development of country, and existing car owning amount reaches 3,000 ten thousand, and annual new car yielding capacity is greater than 6,000,000, and annually rises with the 20-30% increment.But our vehicle maintenance and repair enterprise, still the dependence experience is carried out fault diagnosis basically, and it is many that good enterprise adopts is the import failure diagnosis apparatus, and technology is conservative, and the sensing annex is many, not general, the price height.For example the VAS5053 of import is German at our company, the failure diagnosis apparatus of popular Audi produced in series, and the special train special use, other vehicle of our company all can not compatiblely use.STAS200 is at Benz Co.'s auto-producing failure diagnosis apparatus for another example.Homemade failure diagnosis apparatus DK6500,8800 also is that part minority vehicle can use.
Above failure diagnosis apparatus exists the shortcoming that equipment is bigger, annex is many, technology is conservative, universal performance is poor and price is high, incompatibility Chinese Automobile Industry ' development.
The model utility content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of most of vehicles that are applicable to are provided, and reliable working performance makes the safer vehicle failure reminiscences of automobilism.
To achieve these goals, the technical solution adopted in the utility model is: a kind of vehicle failure reminiscences, it is characterized in that it comprises fuel system sensors, circuitry sensor, transmission system sensor, sound circuit, display circuit, memory circuit, coding circuit and cpu control circuit, described fuel system sensors, circuitry sensor and transmission system sensor output terminal connect the cpu control circuit input end respectively, and the cpu control circuit output terminal connects the input end of sound circuit, display circuit, memory circuit and coding circuit respectively.
The utility model compared with prior art has the following advantages:
1, as the instrument annex of automobile, automobile is diagnosed in good time.
2, eight systems such as the fuel system of automobile, braking system, ignition system, transmission system are carried out sequential diagnosis.
3, adopt 512 storagies, processing result is preserved.
4, processing result adopts audio alert to remind the driver, causes that the driver notes M R.
5, the data of storage can connect printer.
6, show trouble location and adjustment maintenance parameter.
7, adopt coding in time to adjust the parameter of various automobiles.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
A kind of vehicle failure reminiscences shown in Figure 1, it comprises fuel system sensors 101, circuitry sensor 102, transmission system sensor 103, sound circuit 104, display circuit 105, memory circuit 106, coding circuit 107 and cpu control circuit 108, described fuel system sensors 101, circuitry sensor 102 and transmission system sensor 103 output terminals connect cpu control circuit 108 input ends respectively, and cpu control circuit 108 output terminals connect the input end of sound circuit 104, display circuit 105, memory circuit 106 and coding circuit 107 respectively.
As shown in Figure 2, the P1 interface of described fuel system sensors 101 output termination cpu control circuits 108, the P2 interface of circuitry sensor 102 output termination cpu control circuits 108, the P3 interface of transmission system sensor 103 output termination cpu control circuits 108, the P4 interface of sound circuit 104 input termination cpu control circuits 108, the P5 interface of display circuit 105 input termination cpu control circuits 108, the P6 interface of memory circuit 106 input termination cpu control circuits 108, the P7 interface of coding circuit 107 input termination cpu control circuits 108.
As depicted in figs. 1 and 2, automobile will in time carry out the initial data correction of computer after installation, adjust, revise by coding circuit 107, revises the technical order and the requirement of this car.
When automobile is connected power supply, the fault reminiscences enters working state, by fuel system sensors 101, circuitry sensor 102 and transmission system sensor 103, in good time parameter sensing is sent into computer through P1 mouth, P2 mouth and the P3 mouth of cpu controller respectively, compare, handle with initial data, discovery has the variation (variance ratio can be adjusted, select by coding circuit 107) of 1-5%, running parameter can be sent processing result into sound circuit 104 by the P4 mouth and report to the police, and reminds the driver to note.Promote display circuit 105 by the P5 mouth simultaneously, show trouble location and adjust parameter.And data are sent into 512 storagies of memory circuit 106 by the P6 mouth, the result is stored.Offering printer or other computer connects.
Automobile in the process of moving, the fault reminiscences is working state all the time, fault diagnosis, comparison, analysis are carried out randomly, sequentially, repeatedly carried out to parameter to each system sensor, discovery has the variation of 1-5%, just as the automobile initial state, by sound circuit 104 warnings, display circuit 105 demonstrations, the vicissitudinous data of memory circuit 106 storages.
This model utility vehicle failure reminiscences can be used as the instrument annex of automobile, and automobile is diagnosed in good time, also can be used as a testing tool and uses.
