1. an injection machine self-diagnosable system, is characterized in that, comprising:

  • Detection module, is connected with injection machine, at least one performance parameter of injection machine described in Real-time Obtaining;

    Parameter analysis module, is connected with described detection module, for judging described performance parameter whether in respective preset range;

    Display module, with described Parameter analysis model calling, for showing the judged result to each performance parameter respectively;

    Wherein, described performance parameter at least comprises moment of torsion and the rotating speed of motor;

    Described system also comprises;

    Moyor analysis module, with described Parameter analysis model calling, for when described Parameter analysis module judges that described performance parameter is all in preset range, calculates motor driven efficiency and judges that whether described motor driven efficiency is abnormal;

    Motor analysis module, be connected with described moyor analysis module, for when described motor driven efficiency is abnormal, the ratio Kt judging the input current of described motor and described moment of torsion respectively whether in the first preset range, whether the rotating speed n of described motor in the second preset range, and when described Kt not in the first preset range and/or described n not in the second preset range time, generate information and the second cutoff command;

    Second Executive Module, is connected with described motor analysis module and injection machine respectively, for when receiving described second cutoff command, controlling described injection machine and stopping after the second Preset Time.
