Modular autonomous automatic recorder of parameters of thermal pulse processing

The subject of the study is the technical and software methods for constructing digital twins of high-speed processes in a closed working chamber of a thermal pulse machine during the finishing of parts. This work develops a universal modular autonomous device that automatically records the temperature of gases, their pressure, the speed of passage of shock waves and other parameters that directly affect the surface of parts. Research objectives: determine the shape and dimensions of the body of the recording device, assign the location of sensors on it, and develop software and hardware complex for controlling the process of measuring and recording operating parameters for their further use in the work of the digital twin of the process. Because of the work carried out, it was found that the most suitable form for the recorder is an octagonal prism, consisting of parts of only two standard sizes - an octagonal end and prismatic side walls. Parts of the same type are interchangeable. The body shape allows the recorder to be installed in the working chamber vertically, horizontally and rotated with a fixed step of 15° around the longitudinal axis. Depending on the plan of the experiment, the necessary number of sensors of the corresponding type is installed on the walls of the recorder housing in certain places. Since the parts are interchangeable, it is possible to form sets of additional modules with sensors for various purposes and quickly change them during experimental studies. Specialized autonomous non-volatile software and hardware complex has also been developed, which, in the conditions of a limited volume of the internal space of the recorder, automatically starts collecting information from sensors, its primary transformation, and saving the results of the experiment. to an internal permanent storage device and transfer them to a personal computer for further use in the chain of work of the digital twin of the process.
