Abstract
The invention relates to the comprehensive development and employment of driving, safety, energy saving and maintenance engineering of automobiles. Based on a programming principle of a computer, an operation function of an audio engine fault alarm system is additionally arranged on a compatible machine, interlinked sequential machine languages are arranged in a CPU (Central Processing Unit), and a digitalized sound signal is reported by using a loudspeaker through reduced (decompressed) digital-to-analogue conversion.
Description
Technical field
The present invention relates to the comprehensive development and utilization of running car, energy-saving safe, maintenance engineering, belong to the auto repair engineering.
Background technology
When existing running car breaks down, mostly be that self diagnosis fault CHECK pilot lamp shows, perhaps the driver informs the repairman who keeps in repair producer to symptom of vehicle failure, and the maintenance personal realizes man-machine conversation with the decoding appearance, judges maintenance.But to the driver, do not know it is what fault, what harm and consequence is arranged, have or not and to continue to drive to the destination place under repair, reduce unnecessary loss.
Summary of the invention
The objective of the invention is to reduce unnecessary loss,,, design corresponding program language according to the concrete condition of Automobile Design structural principle from economic, practical, durable purpose.When using these language, configuration corresponding assembler, program compiler or program interpreter; Satisfy engine and under various operating modes, obtain best technology status; The kinetic measurement electronic control system is in time reported when breaking down, is in time handled, and reaches the effect of driving safety, economy.
In order to address the above problem, technical scheme of the present invention is: according to the ultimate principle of computer programming, set up engine system fault language and report operation function---fault language alarm.Utilize ECU to keep watch on the working condition of each ingredient of electronic control system; Microcomputer is inner with binary code method information translation, and a series of control program softwares, injection characteristics arteries and veins spectrum, IGNITION CONTROL characteristic arteries and veins spectrum, coolant water temperature performance data etc. are as the raw data data; The instruction and data characteristic is written as a series machines language that connects each other; Pack into behind the central processor CPU, digitized voice signal comes out with loudspeaker plays after passing through reduction (decompression) digital-to-analog conversion.The sensor signal normal value does not promptly start language and reports function, starts language when undesired at once and reports function, reports 3 times, promptly stops, and does not have the failure message of treatment measures to preserve automatically, can restart yet and report live telecast.
The present invention and other engine inspection CHECK pilot lamp, special-purpose failure diagnostic apparatus (decoding appearance) is compared, and meets the ultimate principle of physical electronic engineering science ECU electronic-controlled installation system; According to car engine electronic control device concrete structure, digital quantity signal becomes CPU required standard arteries and veins spectrum through pre-service; Entering counting, frequency measurement, survey cycle draw response, and the parameter of control and detected object is in allowed band, and system failure language is reported operational function and do not started; Do not do information stores yet; Reach software and also can carry out fault diagnosis, find that fault is in time reported, processing in time, technical intelligence language with man-machine interaction system; Be users' service, performance socialization benefit.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified:
Fig. 1 is an engine failure language alarm schematic diagram of the present invention;
Fig. 2 is the basic comprising schematic diagram of ECU of the present invention;
Fig. 3 is engine self-diagnosis of the present invention and other generalized subroutine advance angle of engine ignition software design;
Wherein among Fig. 11 be microcomputer, 2 for filtering and decision processor, 3 be dynamic loudspeaker.
Embodiment
Through specific embodiments the present invention is explained further details below:
On compatible, set up engine failure language broadcasting system during actual the use, inner all information of microcomputer adopt the binary code form to deposit ear, processing, transmission, conversion each other.Microcomputer and filtering and decision processor are got in touch each other, and dynamic loudspeaker is restricted by filtering and decision processor, when engine electric-controlled system breaks down; Filtering and decision processor are sent sound signal to dynamic loudspeaker; Dynamic loudspeaker broadcasts the fault language, broadcasts 3 times according to a cut-and-dried constant, and with the signal value of substituting; Make system works be in the fault operating state, claim again " going to work braving one's illness ".
In the ECU electronic-controlled installation system, input circuit amplifies the various signals of sensor input, filtering, shaping, be transformed to the standard signal that computing machine can be discerned.The control command signal that output circuit sends computing machine becomes can drive the electric signal of each actuator work through treatment conversion such as amplification, conversion.
Fault self-diagnosis and other generalized subroutine advance angle of engine ignition software are at first optimized data to engine speed and load and are deposited in the storer, and the design of subroutine is carried out in top-down master routine design at last.
Claims (4)
1. motor car engine fault language alarm is characterized in that: it comprises that microcomputer (1) and filtering and decision processor (2) get in touch each other, and dynamic loudspeaker (3) is connected with decision processor with filtering and restricted by it.
2. a kind of motor car engine fault language alarm according to claim 1 is characterized in that: set up engine failure language broadcasting system on the compatible microcomputer, inner all information of microcomputer are changed with the binary code form each other.
3. a kind of motor car engine fault language alarm according to claim 1 is characterized in that: when engine electric-controlled system broke down, it was constant 3 times that dynamic loudspeaker broadcasts the language number of times.
4. a kind of motor car engine fault language alarm according to claim 1 is characterized in that: do not have the failure message of treatment measures to preserve automatically, also can restart and report live telecast.
