Cyber-physical systems in this work were considered for the first time to support the reliability of the electronic equipment of a spacecraft during operation in orbit. Considering the requirements for minimizing the mass and dimensions of the spacecraft, it is suggested to relocate the cyber subsystem from spacecraft to the Mission Control Center. An algorithm for the proposed structure functioning of the cyber-physical system is constructed. The novelty of the work is the proposal by the authors beforehand, before launching the spacecraft, to form an exemplary computer virtual model in the Mission Control Center that implements the interconnection of the basic physical processes (electrical, thermal and mechanical) taking place in the electronic equipment.
The virtual model allows taking into account the synergistic strengthening effect from the mutual influence of physical processes on each other. In this case, the error from separate modeling of physical processes disappears. In this paper, the authors give an algorithm for creating a reference virtual model. Telecommands for the correction of the onboard electronic equipment are fed via the radio channel to the actuators built into the equipment, or to the onboard computer, which affects the cyclorama of the equipment operation. A description of the experimental verification of the space cyber-physical system by young specialists, including graduates of the MIEM HSE, which occurred in the rescue of the AngoSat-4 satellite, launched on December 27, 2017.
The article is devoted to the history and problems of creating interfaces. Shows the complexity and importance of effective interfaces, noted that this problem is a system of multilevel interdisciplinary. The new systems should be given serious attention to issues of human efficiency level. Man is still the leading element in determining the efficiency of any ergatic system. The main means of control in ergatic systems including computers, is the graphic manipulator (GM), with which to control the on-screen controls. Are the main styles of user interface. The most popular are GUI-interface (GUI - GraphicalUserInterface) and based on them WUI-interface (WUI-WebUserInterface). The development of equipment and technology of computer modeling led to the active introduction of virtual reality technology to ensure the inclusion of people in artificial worlds. Their main feature - full control of all the parameters of the development and the emergence of a sense of presence in people who live in these environments, which are called immersive. Technology induced environments allow a number of new, not generally applicable to the present, of interfaces using specially engineered virtual environments. Much attention is paid to creating the most advanced systems - systems contact management, which are the camera and sophisticated software. The drawbacks of modern non-contact control. Is being developed to create a contactless intelligent interface, which will allow: to control with data from a video camera, which is installed on your computer have a high noise immunity, clearly identify the user to recognize the situational environment, have an acceptable cost.
The disadvantages of the methodology for calculating the set of spare parts, tools and accessories (SPTA). A multi-criteria methodology for calculating a local package SPTA based on the convolution method has been developed that allows simultaneous use of several optimization criteria (weight, volume, cost). Based on the convolution method, which allows to reduce the multicriterial task to a scalar one. To check the effectiveness of the developed methodology, the calculation of the local package SPTA for the aviation radar complex was carried out using the current one-parameter and developed multi-criteria techniques. The weight and size of the required spare parts kit was used as limitations. On the basis of the results obtained, an analysis was conducted of the effectiveness of the developed methodology.
