1. a kind of method for recognizing mistake, it is used for the control system of medical treatment, diagnosis or medical treatment and diagnostic device (2)(20) in, wherein, methods described includes:

  • The medical treatment, diagnosis or medical treatment and diagnostic device are operated in the normal mode of operation;

    Processing data (D) under the normal mode of operation;

    It is that a safety-critical component (210) of the control system (20) is carried under the test mode of the control system (20)Inspection data (E) for coming from an inspection data collection T (E, A), the inspection data includes value pair, and the value is to being included in the peaceThe input value (E) occurred in the real operational processes of fully closed key asembly as data, and described value is to including by the safetyThe anticipated output value that key component corresponds to the input value under the normal mode of operation correctly simulated and produced, the inputValue includes position data;

    AndThe safety-critical component under the test mode is examined using the processor of the control system, the inspection includes:

    Calculated based on the input value and examine output valve, the calculating includes:

    Inspection institute states the uniformity of position data, and the uniformity that inspection institute states position data includes being verified the inspection of sumTest, the position data includes the related coordinate of axle;

    By the related coordinate forward conversion of the axle into cartesian coordinate;

    The first truthlikeness inspection is carried out, the first truthlikeness inspection of progress is included the cartesian coordinate and predetermined flute cardYou compare coordinate;

    Cartesian coordinate is changed according to standard;

    The uniformity for the cartesian coordinate changed or the second truthlikeness inspection, the uniformity of progress or the inspection of the second truthlikenessLook into including testing or verify and;

    AndBy the inspection output valve calculated in test mode with by the safety-critical component it is described correctly simulate it is normalThe anticipated output value produced under mode of operation compares.
