The invention relates to a computer device for the generation of executable programs, comprising a user interface for entering a model based on a program with a executable commands, a generator for generating of individual programming code from the model, a state machine for executing the executable program, means for providing predefined programming code which has the form of at least one basic class or other predefined code for providing repeating algorithms. The user interface has input means for inputting executable commands in a graphical form. The entry points into the program are formed by parts of the predefined programming code for the state machine. The model also comprises graphic symbols representing instantiated classes, and the user interface comprises means for defining a direct relation between the input and output of data by a program user and attributes of the instantiated classes.

The invention discloses an online identification method for a gas-liquid two-phase-flow flow pattern in a gathering and transportation-vertical pipe system. The online identification method is used for pre-processing a vertical pipe top pressure signal to be identified of the gathering and transportation-vertical pipe system; a characteristic parameter vector comprising three main components is extracted through statistical parameter calculation and man component analysis; then the characteristic parameter vector is input into a multi-class classifier of a pre-trained least squares support vector machine, so that the attribution of the vertical pipe top pressure signal in four basic classes including a first type of serious section plug flow, a second type of serious section plug flow, a flow pattern for transiting to the serious section plug flows, and a mixed type flow pattern of vibration type serious section plug flow and stable flowing; when the attribution belongs to the mixed type flow pattern of the vibration type serious section plug flow and the stable flowing, characteristic parameters in two frequency regions of the signal to be processed are input into two types of trained classifiers to determine the final attribution. The online identification method has high identification rate, strong portability and good field adaptability, and can effectively meet the online identification requirements.

The invention discloses a method and a device for realizing mode switching of equipment in an automated test. The method comprises the following steps of: abstracting a basic feature, which serves as a base class of an equipment control library, of the equipment, wherein the basic class comprises a switching control command of a content mode and a switching control command of a working mode; calling the switching control command of the content mode or the switching control command of the working mode in the base class according to a target mode output by the equipment to obtain specified equipment; and after an equipment test process is scripted, performing a test command of a script to obtain a test output result, wherein the script succeeds a control command of the specified equipment. The device comprises a base class acquisition unit, a specified equipment unit and a test result output unit. In the method and the device provided by the invention, a user can call a control method in the base class to specify a certain type of equipment and an interface is provided for a scripting process, so that the equipment is controlled more conveniently and flexibly and has higher expansibility.
