| Sumario: | The introductory part of the article provides information that JSC "Element" is one of the leading enterprises of Ukraine in the scientific and technical direction "Electronic systems for measuring, monitoring parameters and aircraft engine control". As a result of cooperation between the team of Element JSC and a number of divisions of Motor Sich JSC, software and hardware complexes (SHC) were developed to automate the technological processes of bench tests of aircraft engines. For 15 years, about 20 such SHCs have been supplied to Motor Sich JSC and other enterprises. An important task of Element JSC was to provide support for its hardware and software complexes, to promptly resolve issues related to their performance and modernization as new requirements and technological processes emerge. The SHC Polygon became the main tool in solving these problems. The description of the SHC Polygon is given, which is a functionally standard SHC, but with a reduced composition of measuring modules. The SHC polygon consists of two hierarchical levels: lower and upper. The upper level of the PTK Polygon is a device for communication with the object, the main tasks of which are the transformation of parameters coming from the sensors and the primary processing of information, control of technological operations, and emergency protection of the engine. The upper level is two workstations that display information and provide interaction between the operator and the system. The Polygon SHC includes a software product (SP) operating in the environment of the QNX 4.25 real-time operating system. The main feature of the SHC Polygon is the ability to launch the SP of any of the developed SHC, adapted to work with the existing set of measuring modules. A list of the most frequently performed works in the course of post-warranty maintenance of the hardware and software complex, including the introduction of new technological operations and algorithms, is given. It is noted that the SHC Polygon turned out to be a successful solution for remote support of aircraft engine tests at the stands of Motor Sich JSC. It allows you to solve most of the problems identified in the operation of the equipment of test stands and hardware and software systems, and also provides modernization and refinement of algorithms without specialists visiting the site. The possibility of remote maintenance of the SHC is especially important in the context of the Covid-19 pandemic and quarantine restrictions in Ukraine. |
