Abstract
The invention discloses an electrically controlled engine fault code reading method and device. The method comprises the steps that engine fault codes are read via a host VCU controller arranged on a machine provided with an electrically controlled engine through a CAN communication bus. A host is internally provided with all the engine fault codes which are pre-stored in a code storage device, and text explanation of each code. The read fault codes are compared with the fault codes stored in the code storage device by the host so that corresponding fault code information is retrieved. One path of the retrieved fault code information is transmitted to a displayer, and the other path is stored in a historical record storage device in the host for future reference. Complex code hints are transformed into humanized text hints, and fault categories and maintenance categories are distinguished. Faults belonging to manufacturer maintenance are directly informed to manufacturers so that diagnosis and maintenance time is shortened and energy consumption is reduced, maintenance personnel can be assisted to directly and rapidly acquire the fault points of the electrically controlled engine, and thus diagnosis and maintenance time can be substantially shortened.
Description
Technical field
the present invention relates to a kind of deciphering method and device of electric-control motor failure code, belong to engine failure detection technique field.
Background technology
electric-control motor controls comparatively more complicated than the control of mechanical engine, for general user and maintenance personal, its maintenance difficulty is far longer than mechanical engine, and the failure code total number of electric-control motor often reaches hundreds of thousands of, but concerning maintainer, have the overwhelming majority to be unpractical, and read failure code and know its implication very bothersome even lack condition time cannot know.
it is all read by flashing times and the rule or received on diagnose interface by separate diagnostic instrument read about alarm lamp usually that the failure code of electric-control motor reads.Accurately to read flashing times to need repeatedly carefully to read, very inconvenient, also may misread, particularly when fault number is more, and need failure code table after read failure code and just can detect defect content, and the failure code number of electric-control motor is tired many, look into both consuming time, again effort.Read as by diagnose interface, need separate diagnostic instrument, and this instrument is generally with strong points, expensive.
Summary of the invention
the object of the invention is to, a kind of deciphering method and device of electric-control motor failure code are provided, help users and ordi-nary maintenance personnel to obtain failure code and implication thereof rapidly smoothly, know which fault by engine factory repair, can only avoid waste plenty of time and energy.
technical scheme of the present invention:

in aforementioned deciphering method, the failure code in described code memory and explanation are stored in field service personnel and manufacturer maintenance personal two first grade files folders respectively; Field service personnel file comprises maintenance, warning fault and critical failure three second grade file folders, and manufacturer's maintenance personal's file comprises warning fault, critical failure two second grade file folders; Can according to condition query history record by history memory.
in aforementioned deciphering method, described when inquiring about failure logging in history memory, by input through keyboard user type, user type comprises field service personnel, manufacturer maintenance personal and designer's three types; When user type is field service personnel, the failure code information only stored in retrieval field service personnel file; When user type is manufacturer maintenance personal, the failure code information only stored in retrieval manufacturer maintenance personal file, to shorten retrieval time; When user type is designer, the failure code information in retrieval All Files folder, for designer provides improvement foundation.
in aforementioned deciphering method, be provided with perpetual calendar and clock generator in described main frame, when record retrieval failure code information, the record retrieval time is for future reference simultaneously.
solution read apparatus according to of the present invention a kind of engine failure code of above-mentioned deciphering method structure is, this device comprises the main frame VCU controller be connected with electric-control motor ECU controller through CAN communication bus, and color screen monitoring device is connected with main frame VCU controller through CAN communication bus; Be provided with indexing unit in main frame VCU controller, indexing unit is connected with failure code storer and history memory, and history memory is connected with date and time generator.
in aforementioned solution read apparatus, described color screen monitoring device is provided with the color monitor, hummer and the keyboard that are connected with console controller through CAN communication bus.
compared with prior art, the present invention becomes the prompting of loaded down with trivial details code into the word of hommization and auditory tone cues and distinguishes fault category and maintenance classification.Shorten diagnosis, the time of safeguarding and reduce efforts.Users and ordi-nary maintenance personnel can be helped comparatively directly to know rapidly electric-control motor trouble spot.Avoid trouble and the flickering code that may make mistakes reads and helpless without during professional diagnosis instrument; Substantially reduce diagnosis, the time of safeguarding and reduce efforts.
