Description
Technical field
The invention belongs to vehicle teaching technical field more particularly to a kind of automobile basic circuit fault diagnosis checking systems
And method.
Background technology
《Implement automobile circuit primary to safeguard》During course teaching, learner can know in addition to master basic knowledge
Outside figure, analysis circuit figure, an also important basic skills --- event can be carried out to circuit with examination lamp, multimeter and jumper
Barrier investigation.The technical ability for using " examination lamp ", " multimeter ", " jumper " progress automobile circuit breakdown diagnosis currently for student is examined
Kernel mode is still based on manually examining.The process of the examination of student is very long waiting process, and general every teacher supervises simultaneously
The time spent in examining 1 student of 2 students or even invigilator, completing the examination of full class or annual grade student is very long, examination
Be over the work order that also spend a lot of time and arrange student, improves performance rating;Because the examination time is long, invigilator teacher may go out
The difference of existing fatigue or each invigilator's teachers ability level, judges the score of the examination of student by accident;Artificial examination process
In, invigilator teacher may be different to " impression " of student, and also the score of the examination can be had an impact.
In conclusion problem of the existing technology is:Efficiency of the practice is low.Examination process, work order arrange and achievement is commented
Surely it can spend a lot of time;Implementing the phenomenon that examination is judged by accident in the process can not avoid;The fairness of examination process.
Invention content
In view of the problems of the existing technology, the present invention provides a kind of automobile basic circuit fault diagnosis checking systems
And method.
The invention is realized in this way a kind of automobile basic circuit fault diagnosis checking system, automobile basic circuit failure
Diagnosis checking system includes:
Basic circuit is used to implement switch control relay, then controls light bulb by relay;
Failure projects circuit, controls 19 relays by microcontroller, in real time projects 19 failures in basic circuit
It goes;
Display screen is used to implement fault setting and the display of diagnostic result;
Microcontroller is used to implement the control to serial ports screen information exchange and failure projection circuit.With serial ports screen information exchange
It is realized by voidIOTask (void*p_arg) task;Failure projection circuit control is by void ControlTask (void*p_
Arg) task is realized.
19 relays are controlled by microcontroller, " failure " is projected to a kind of automobile base gone in basic circuit in real time
This circuit fault diagnosis checking system, the automobile basic circuit fault diagnosis checking system include:Basic circuit, failure are thrown
Transmit-receive radio road, display screen and microcontroller.Microcontroller is connected with display screen by serial ports, realizes the event that failure setting, student confirm
The interaction of the information such as barrier and position;Microcontroller is controlled by GPIO interface and projects circuit by the failure that 19 relays form, real
When will setting " failure " project in basic circuit;Basic circuit is that common relay control bulb circuit is on automobile
12 positions (including 7 section lead positions) in circuit are together in series by basis with failure projection circuit respectively.
Another object of the present invention is to provide a kind of side of the automobile basic circuit fault diagnosis checking system
Method, the automobile basic circuit fault diagnosis checking system realization include the following steps:
Step 1, student click button screen when button bounces, and screen is sent to microcontroller serial port by serial ports and touched
Message.
Message format:0X65 page ID button ID end marks
Step 2 after microcontroller is connected to message, (is connect to IOTask tasks transmission data update characteristic events by serial ports
It receives interrupt routine to realize).
IOTask tasks can authorize operation by data update mark or End Event flag set.
Step 3, IOTask tasks go to read screen data, and be saved in system variable according to update characteristic events.
IOTask tasks send out display data to screen according to button information or changing interface instructs, and are sent out to ControlTask tasks
Task message.
Step 4, ControlTask tasks handle control failure projection electricity in real time according to the screen data of reading
Failure projection is realized on road.ControlTask tasks realize countdown function simultaneously, switch system mode when the time is 0
To examination end state, and set End Event flag bit.
Step 5, IOTask tasks send out student's examination knot because authorizing operation after End Event flag bit set, to screen
Fruit inventory terminates examination.
Explanation:
1) system variable is structure variable, and Major Members variable is as follows:
Vsystem.DLCSet- failures setting variable (data format such as following table)
Vsystem.DLCDart- failures projection variable (data format is same as above)
Vsystem.DLCUser- user's confirmation message (data format is same as above)
Vsystem.DLCStatus- troubleshooting stages (data format is same as above)
Vsystem.Time- test times variable (when being 0, examination terminates)
Vsystem.EventStatus- event flags group (every represents different event)
Vsystem.Status- system state variables (enumeration type variable, have examination before, examination in, examination terminate, failure
4 kinds of states are set)
2) DLCSet data types explanation:
For variable for 32 without symbol shaping variable, Bit24-Bit31 is retention position 0, and when corresponding position 1, which represents, to be existed
Failure;Fault-free when setting to 0.
3) it is that student confirms number of faults by calculating 1 units in vsystem.DLCUser variable binary digits;
The position for calculating in vsystem.DLCSet variable binary digits 1 is failure setting quantity;Failure projects variable
Vsystem.DLCDart=vsystem.DLCSet& (vsystem.DLCSet^ vsystem.DLCUser);
4) ControlTask tasks are by judging whether vsystem.Time is 0 or confirms whether number of faults is equal to event
Barrier setting quantity, if condition meets puts 1 by End Event mark, triggering IOTask tasks export fault clearance result to screen
That is vsystem.DLCSet and vsystem.DLCDart variables and achievement.
5) after serial ports screen receives data, by upper sheet format to vsystem.DLCSet and vsystem.DLCDart data
It can obtain failure setting and fault clearance result after step-by-step processing.
The present invention is in practical applications, highly stable;Make student is allowed to practice examination lamp, multimeter and jumper in teaching
It uses, student is allowed to grasp more secured to examination lamp, multimeter and the use of bridging;Examination can also multiple devices simultaneously into
Row improves examination efficiency, if each teacher is examined to invigilate two students in a conventional manner, with equipment examination, each invigilator is old
Teacher can monitor simultaneously 4 it is even more, efficiency is that 2 times manually examined are even more.
