Abstract

A variant of the construction and production of aviation measurement and computing complexes is proposed, the relevance is justified by the need for import substitution in the current international situation and the need to develop domestic high-tech products. A variant of modular construction of on-board equipment with stackable characteristics is considered to create scalable automated measuring and control tools designed for multifunctional operation in harsh climatic conditions of use, taking into account increased requirements for reliability and technical characteristics. The article considers the device and operating principle of a single-board module designed to create scalable aviation measurement and computing complexes, as well as the option of combining them through integrated integration tools. One of the main advantages of the proposed approach in production is the use of domestic computing facilities and operating systems with extended interface databases, including not only traditional electrical data transmission interfaces – ARINC-429, the main information exchange channel, and others, but also the modern FC-AE optical interface. Using the examples of integration channels, a comparison of scaling levels in a single-board module is performed. An information exchange protocol has been developed with the adoption of technical agreements. Based on a new domestic high-performance clustered computing platform for single-board modules, the possibility of building a high-speed object LAN using an original highly reliable physical environment is being considered. When solving the problems of building such local area networks, priority is focused on ensuring a high level of noise immunity, reliability and fault tolerance of a broadband physical distribution environment using fiber-optic cables as communication lines.
