There is a well-known (RU, certificate for utility model 17980) stand for the development and verification of on-board equipment (BWC) complexes, containing the BWC itself as part of the on-board computer system (BTSC), the BWC display and control system as part of two identical multifunction control panels (MFPU1 and MFPU2 ), which are simultaneously interconnected with the digital air navigation system, two identical navigational and planning indicators (INP1 and INP2), simultaneously connected with the digital air conditioning system, two identical display processors (DP1 and DP2), which are simultaneously interconnected by multiplexes channel of information exchange (ICIE) with the BCVS, five multifunctional indicators (MFI1, MFI2, MFIZ, MFI4 and MFI5) and a collimator aviation indicator (KAI), interconnected simultaneously with DP1 and DP2, as well as all on-board information and executive systems with an interface GOST 26765.52-87, interconnected with the BCVS through the first and second MKIO (MKIO1 and MKIO2) and all on-board information and executive systems with a serial interface according to RTM 1495-75, and a panel for simulating one-time commands (PI K), associated with the BCVS, the MKIO technological monitor, interconnected with the BCVS via the MKIO1 and MKIO2, the multi-channel serial signal switch (MPKS), simultaneously interconnected with the BTsVS and all on-board information and executive systems with a serial interface via RTM 1495-75, a technological integrated information system associated with the exit from the MPKS.

Known (RU, certificate for utility model 18198) stand for the development and verification of on-board equipment complexes. The well-known stand contains an on-board computer system (BTsVS), a panel for simulating one-time commands connected to the BTsVS, a reprogrammable memory unit (PDU) interconnected with the BTsVS, two identical multifunctional control panels (MFPU1 and MFPU2) interconnected with the BTsVS, two identical display processors ( DP1 and DP2), interconnected through a multiplexed information exchange channel (ICIE) with the BCVS, five multifunctional indicators (MFI1, MFI2, MFI3, MFI4 and MFI5), a collimator aviation indicator (KAI), interconnected m of television channels and channels of serial signals of the RS-232 type simultaneously with DP1 and DP2, moreover, three technological electronic computers (TEVM1, TEVM2 and TEVM3), two multiplex signal interface adapters (AIMS1 and AIMS2), multi-channel and single-channel serial interface interface adapters (AIPSM and AIPSO), with TEVM1 through AIMS1 and the first multiplex information exchange channel, TEVM2 through AIMS2 and the second multiplex information exchange channel, TEVM3 through AIPSM, one temporarily interconnected with BTsVS, while TEVM3 through AIPSM and AIPSO is also interconnected with TEVM2. This technical solution was taken as the closest analogue.

As the disadvantages of the closest analogue, as well as the disadvantages of the other analogues listed, the following can be noted:

- there is no information on the use of the single time service as a part of the bench equipment, which ensures the interaction of the TEVM1, TEVM2, TEVM3 of the stand in real / model time scale;

- the device does not have an information exchange channel that provides interaction between components of bench equipment. The absence of such an exchange channel does not provide multi-machine distributed modeling and does not allow testing the test object using simulation models of systems with a set of different interfaces. Due to the above, the determinism of the experiment is not ensured;

- there is no provision for automatic launch of tests and automatic generation of test protocols. The absence of this mechanism leads to a significant increase in the execution time and affects the repeatability of the tests, increases the influence of the "human factor" when reusing tests;

- one-time commands issued to the test object (in the BCVS) are set using the panel to simulate one-time commands manually, which significantly affects the quality reduction, increases the testing time and reduces the repeatability of the tests.

The technical problem to be solved using the developed device is the creation of a universal tool (stand and software environment) designed for testing information and control systems of aircraft systems, as well as individual components of systems.

The technical result, the invention is aimed at, is to expand the capabilities of the checks carried out at the integration complex of the information management system (IC IMS) for compliance of the characteristics of the created complex with the requirements of the statement of work (TOR), including solving the following tasks at the stand: conducting functional testing individual software components, hardware input control, hardware performance check, i.e. checking the conformity of the functioning of the IMS blocks of devices and channels to the requirements of the information interaction and TK protocols, debugging the IMS software on the target platform (integration of the IMS blocks, hardware and software integration), the integration of the IMS software components, the integration software testing, in which the integration of functional software components is tested ( FPO) with each other, up to the full integration of the FPO of individual IMS units, incl. service software (STR) and components coming from enterprises - co-developers; testing the integration of software and hardware of the IMS, in which they test the joint functioning of open source software, software and hardware, integrated testing of equipment for solving information interaction problems, integrating information and applied tasks of IMS, including navigation and flight tasks and combat application tasks, qualification testing of IMS, in which the IMS as a multicomponent hardware and software system is tested for compliance with system requirements, the primary diagnostics of the IMS blocks are carried out, according to which tupili complaint, as well as acceptance tests ICS.

The specified technical result is achieved by the fact that the stand contains control equipment, including at least an instrumental machine of private models (IM FM) 1, an instrumental machine for recording parametric information (IM REG) 2, at least one automated workplace of an engineer -experimentator (AWP IE) 3, automated workstation - repository of model data (AWP RPZT) 7 interconnected by a high-speed deterministic real-time channel (DKIOS RT) 8 with multi-machine distribution unit testing of the test object (OI) 18 (for example, information management system), and also contains testing and modeling tools (STIM) 6 that provide tests, verify the interaction of OI 18 with software models of external systems in program / real time, and may also include in its composition equipment for simulating television signals (AIS TV) 11 and equipment for simulating one-time commands, analog signals (AIS RKAS) 12.

The totality of the technical features of the IC IUS stand is that it contains control equipment, including automated workstations of experimental engineers (AW IE) 3, instrumental registration machines (IM REG) 2, an automated workstation - repository (AWP RPZT) 7 apparatus for simulating television signals (AIS TV) 11 and apparatus for simulating one-time commands and analog signals (AIS RKAS) 12, interconnected by a bench high-speed real-time channel (DKIOS RT) 8, and also contains testing and modeling, which ensures the achievement of a technical result for checking the created complex and components for compliance with the requirements of the technical specifications and with an additional qualitative expansion of the checks (test object (OI) 18) can be both an information management system and its individual components), including at the stand it is possible to carry out functional testing of individual software components (software), incoming control of equipment, checking work petitiveness hardware, software debugging on the target ISC, the integration of software components ICS, integration testing PVD, wherein the functional integration of components tested software (PVD) between themselves; testing integration of IMS software and equipment, comprehensive testing of equipment for solving information interaction problems, integrating information and applied problems of IMS, qualification testing of IMS, primary diagnostics of IMS blocks for which complaints have been received, as well as acceptance tests of IMS. As a result of expanding the list of tasks performed at one stand - reducing the time of testing the test object and increasing the development efficiency.

The developed device differs fundamentally from the technical solution - the closest analogue in that a high-speed deterministic real-time channel based on Ethernet technology (hereinafter referred to as DKIOS RT) 8 channel, which is designed for the interaction of component parts of the test bench (IM FM 1, IM), is introduced into the structure of the IC IMS stand REG 2, AWP IE 3, AWP RPZT 7, AIS TV 11, AIS RKAS 12). In addition, in the stand (in IM World Cup 1, IM REG 2, AWP IE 3, AWP RPZT 7, AIS TV 11, AIS RKAS 12), STIM 6 software was implemented that provided the preparation and execution of tests.

The presence of the DKIOS RT 8 channel and STIM 6 means, in contrast to the closest analogue, allows automatic start of tests (launch control is implemented via the user interface in AWP IE 3, the test script is run in IM FM 1, AIS TV 11, AIS RKAS 12, values parameters are recorded in the IM REG 2 and controlled with AWP IE 3, the final test results are stored in AWP RPZT 7) and automatic generation of test protocols (protocols are generated and stored in AWP RPZT 7).

The issuance of one-time commands in the OI 18 is carried out using equipment simulating one-time commands and analog signals (AIS RKAS) 12, in contrast to the closest analogue, where the issuance of one-time commands is carried out manually by toggle switches. AIS RKAS 12 is a hardware and software designed to receive and issue one-time commands, analog signals in OI 18 (for example, in the IMS), as well as to register analog signals and one-time commands with the formation of registration results with the issuance of control equipment stand (IM REG 2). The issuance of one-time commands, in contrast to the closest analogue, is carried out in accordance with the general test scenario (and not manually), which allows automatic testing to be performed, as a result of which the test time is significantly saved and the results are repeatable.

The IC IMS stand provides multi-machine distributed testing of OI 18 (including IMS), and also provides test execution, verification of the interaction of the verified OI 18 with software models of external systems interacting with OI 18 in program / real time. The DKIOS RT 8 channel allows the integration of various simulation and semi-natural simulation stands, created on the basis of the principles of the IC ICS stand.

The presence of an automatic test run mechanism reduces the testing time and affects the repeatability of test execution, reduces the influence of the “human factor” when reusing tests, which affects the quality and time of test execution.

The information-control system is integrated on the stand of the following components: information-control field (including equipment of multifunctional display units and specialized software that provides the formation of the display and the issuance of control actions of the pilot), on-board digital computer system (including on-board computers and specialized software that provides the necessary calculations for solving control problems, navigation, etc.), signal concentrator blocks s (providing reception / withdrawal of analog signals, discrete commands from outside the aircraft) and provides their interaction with the computing system.

The individual components of the IMS equipment are connected by inputs and outputs along communication lines between each other (for example, VOLSD 10, BMKIO 9, KDPK 13, KRKAS 15). The information management system installed on the aircraft interacts with the inputs and outputs (via the on-board data transmission channels) with other aircraft systems (for example, navigation).

Airborne data transmission channels (VOLSD 10, BMKIO 9, KDPK 13, KRKAS 15) are designed to ensure the interaction of bench equipment with OI 18. The specialized airborne interfaces include such channels as:

- one-time commands (electrical interaction is carried out on copper wires). One-time commands are issued / received in accordance with GOST 18977-79 (they are used to generate emergency, warning, notification and service signals of airborne equipment. For example, one-time commands issue a warning signal about the position of the landing gear (chassis is released / removed, commands are issued to enable glass heating, turning off glass heating due to overheating, command for the presence of connected airfield power supply);

- code lines of communication (copper twisted pair in the screen). Information is transmitted by a bipolar serial code in accordance with GOST 18977-79 and RTM 1495-75 rev. 3., multiplexed channels of information exchange (specialized interface - twisted pair in the screen, in the embodiment with transformer isolation) in accordance with GOST R 52070-2006, bidirectional fiber-optic channels for data transmission FC-AE-ASM (PSNA profile, P -1.1.42-2006 amend. 1). Code lines of communication, multiplexed data exchange channels and fiber-optic channels for data transmission are used to receive / transmit data from sensors, for example, the coordinates of the current position of the aircraft in space, the coordinates of the intermediate points of the flight route, the coordinates of the characteristic features of the terrain. The type of line used for information exchange with the sensor is determined by the amount of information necessary for receiving / transmitting;

- unidirectional fiber-optic channels for transmitting video information (according to the ARINC 818 standard, AC 1.1.818-1-2008);

- analog signals received / issued on copper wires, representing electrical quantities (voltage, current, resistance, frequency) received from the sensors. Electrical quantities carry information about physical quantities, for example, the angle of attack and glide of an airplane, cabin temperature, position signals of engine control sticks and other motion parameters, the position and operation of aircraft avionics systems. Analog signals at the IC ICS stand are simulated by AIS RKAS 12.

The stand can be modified, upon request, with additional channels of interaction with OI 18, for example, channels based on CAN bus.

During operation of the IC IMS test bench, the necessary effects from the external systems of the onboard equipment complex (interacting with the aircraft on the airplane) are simulated, and the results from the test object are received and processed by the test bench equipment. At the stand, work is carried out, both with the individual components of the information management system, and the whole system is being integrated. As a result, the information management system (OI 18) integrated from the individual components obtained as a result of work at the IC IMS stand. The scope of work and the components from which the information management system is integrated are listed above.

The invention is illustrated in the drawing, which shows a diagram of the IC ICS.

Below is a detailed description of the components of the stand

Stand IC IMS contains at least one instrumental machine of private models (IM FM) 1. IM FM 1 is usually a high-performance personal computer with testing and modeling tools installed on it (STIM) 6. IM FM 1 is designed to ensure the execution of the test scenario with the participation of all bench equipment (with control and data exchange on the channel DKIOS RT 8). Also, IM FM 1 exchanges data directly with test facility 18 via high-speed communication lines VOLSD 10, BMKIO 9. The stand may include one IM 1 or several. The number of IM FM 1 in the hardware and software of the stand is determined based on the nomenclature and volume of simultaneously tested interfaces of the test object and the volume of testing algorithms. The presence of several IM FM 1 provides a simple formation on the basis of the IC IMS stand of separate stands for checking the components of the IMS, which allows to increase the testing depth of each of the components of the IMS while reducing the testing time.

Also, the hardware and software of the stand includes IM REG 2, which are high-performance personal computers with STIM 6 tools installed on them, which ensure the registration of transmitted information through information exchange channels. For the convenience of analyzing the obtained test results, it is possible to present the information recorded in the REG 2 information in a parametric form - the parameter values are analyzed for compliance with the required ones. During the work, it is possible to register and analyze such parameters as: a given flight speed, a predetermined flight altitude, fuel balance and other motion parameters, the position and operation of aircraft avionics systems.

The number of IM REG 2 in the hardware and software of the stand is determined based on the nomenclature and volume of simultaneously recorded interfaces of the test object. The presence of several IM REG 2 reduces the need for channel switching and ultimately reduces testing time.

Simulator Aircraft Controls (ISOU 4) are connected to IM 1: simulators of engine control knobs, aircraft control knobs (RUS) and pedals, which are specialized input devices (aviation joysticks). The interaction of ISOU 4 with IM FM 1 is carried out through communication lines of simulators of aircraft control bodies (LS ISOU).

IM FM 1 through DKIOS RT 8 are interconnected (if IM FM 1 is several), as well as through DKIOS RT 8 are additionally connected with IM REG 2, AWP IE 3, AWP RPZT 7, AIS TV 11 and AIS RKAS 12.

The DKIOS RT 8 channel is a specialized bench channel for information exchange and is designed for the interaction of the components of the stand (instrumental machines of control equipment, simulators of real systems) and provides multi-machine (i.e., with the participation of the required number of IM FM 1, AIS RKAS 12, AIS TV 11, IM REG 2, AWP RPZT 7) distributed simulation in real time. The DKIOS RT 8 channel also allows integration of various simulation and semi-natural simulation stands.

IM FM 1 through CCK 17, through channels BMKIO 9, KDPK 13, connected with OI 18; IM FM 1 through drugs ISOU 5 associated with ISOU 4; IM REG 2 through OSK 18 and SSK 17 through channels VOLSD 10, BMKIO 9, KDPK 13 are connected with OI 18.

The IC IUS stand includes automated workplaces of an experimental engineer (AW IE 3). AWP IE 3 are designed to control the execution of experiments, preparation of experiments. AWP IE 3 within the framework of this technical solution is a personal computer designed for the development of tests and information models and providing general control of instrumental machines of private models (IM FM) 1 (the formation of commands to start / stop the experiment from the operator) through DKIOS RT. The structure of the stand provides for the connection of any number of AWP-IE 3, including remote connection for performing autonomous testing of FPO. The presence of separate automated workplaces IE 3 allows for the simultaneous preparation, execution and analysis of experimental results, which leads to a reduction in the required testing time.

Additional AIS RKAS 12 is a hardware and software designed for receiving and issuing one-time commands, analog signals in OI 18, as well as for receiving analog signals and one-time commands with the output of the results to the control equipment of the stand IM FM 1 and IM REG 2 .

Additional AIS TV 11 is a hardware and software designed to simulate and register uncompressed digital video information transmitted via FOCL 14, including: for generating and issuing video information in OI 18; registration of video information issued from the OI 18 through the channels of the fiber optic link 14; registration of video information of the intra-system VOLSV 14 channels in OI 18 (if available, without interruption of exchange). AIS TV 11 allows both visual and automated monitoring of the compliance of the characteristics of the complex being created with the requirements of the technical requirements when receiving / issuing television signals via VOLSV 14. This option is currently necessary due to the possible presence of reception equipment in the information and control systems / broadcasting television information.

The interaction of the control equipment of the stand, AIS RKAS 12 with OI 18 is carried out through the interfaces BMKIO 9, KDPK 13, KRKAS 15 (via the cable network of information exchange) through the bench switching system (CCK) 17, which is a closed panel with electrical connectors located in the hardware cabinets. The switching system CCK 17 provides both the transmission of information from the source to the receiver, and the transmission of the necessary information for registration in the IM FM 1 and IM REG 2.

The interaction of the control equipment of the stand and the equipment for simulating AIS signals (11, 12) with OI 18 VOLSD 10 and VOLSV 14 (via fiber-optic communication lines) is carried out through OSK 16, which is a closed panel with optical connectors located in hardware cabinets. The OSK 16 switching system provides both the transmission of information from the source to the receiver, as well as the transmission of the necessary information for registration in IM FM 1 and IM REG 2.

At the IC IMS stand, a single repository (AWP RPZT) 7 was used to store private models of simulated systems, test scenarios, and test results. AWP RPZT 7 is a high-performance computer (server) equipped with large-capacity disk drives. The presence of AWP RPT 7 allows you to store the full amount of tests necessary to achieve a technical result, generate reports on the results of testing, quick access to all test scenarios, test results.

At the ICS IC stand, STIM 6 tools are provided as part of the bench equipment, which are software tools that provide preparation and execution of software models of interacting systems, provide storage of previously prepared software models, contain tools for describing the configuration and settings of the experiment, means for controlling the experiment, tools analysis of the results of the experiment, and also provide automatic execution of test scenarios with the registration of results. STIM 6 tools consist of a development and model execution environment, as well as a repository.

- Model development environment - an integrated software environment for describing models, which provides a description of the configuration and settings of the experiment, means of controlling the experiment, means of analyzing the results of the experiment.

- Model runtime

The runtime of models, which ensures the run of simulation models in a single model time, the interaction of models and the coordination of model and astronomical time.

- Repository - a base for storing the source texts of models, configurations of stands and experimental results.

STIM 6 tools allow the integration of various software simulation models, the so-called "private models" (hereinafter FM), the integration of FM with real equipment samples. STIM 6 tools ensure the functioning of the FM set in real time, provide the accumulation and reuse of FM, version management: the work of several users on a project, access control to models and tools of the environment, experiment management (setting the stand configuration, parameters, setting the registration level and operational display of events), registration of events in the semi-natural complex; bringing together the streams of events from various registrars - visualization of the functioning and analysis of the quantitative characteristics of the complex. The presence of software tools STIM 6 provides a wide range of checks to achieve a technical result. STIM 6 funds are part of IM World Cup 1, IM REG 2, AWP IE 3, AWP RPZT 7, AIS TV 11, AIS RKAS 12.

Stand IC IMS works as follows.

In the automated tools of AW IE 3 according to pre-prepared algorithms (particular systems models, tests), the engineers working at the test bench form the input / output data of the OI 18 necessary for checking the test mode and determine the information exchange channels through which the exchange with the tested system is carried out, prepare a test case. Prepared test scenarios are stored in AWP RPZT 7.

On AWP IE 3, the operator selects packages of executable test code stored in AWP RPZT 7 and launches a test script for execution. Downloading packages of executable test code occurs through the DKIOS RT line.

From AWP IE 3, through the DKIOS 8 line, a command is issued to synchronously start the test in all IM FM 1 and the test is started in IM FM 1, while in each of IM FM 1, in accordance with the test, variable values are generated and transmission lines are determined information on which the generated information packages are issued to the test object (channels VOLSD 10, BMKIO 9, KDPK 13). The analog signals of the systems are generated on the basis of the obtained model data on the DKIOS 8 line from the IM FM 1 using the AIS RKAS 12. Video signals are transmitted through the VOLSV 14 channels from the AIS TV 11 based on the control signals from the IM FM 1 through the DKIOS 8 channel.

After processing the influences received from the control equipment through the information exchange channels, OI 18 generates the necessary information messages, which are returned in the reverse order to IM FM 1 (via VOLSD 10, BMKIO 9, KDPK 13 channels), to AIS RKAS 12 (one-time commands and analog signals ) and on AIS TV 11 (VOLSV channels 14). From AIS RKAS 12 and AIS TV 11 through the channel DKIOS RT 8 information is issued in IM FM 1.

In the World Cup, the response of OI 18 is either compared with the idea of the correct reaction (during the static testing described in this test), or is used to form an effect on OI 18 for the next modeling step (during dynamic testing or modeling).

IM REG 2 register data in the external interfaces of OI 18 in a single stream and transfer them via the DKIOS RT 8 inter-machine exchange channels to the AWP RPZT 7 computer, where all the information about the experiment is concentrated for the subsequent analysis of the obtained results.

After testing, the results of the tests from IM World Championship 1, AIS RKAS 12, are saved and stored in AWP RPZT 7. According to a predefined template, a test report is generated automatically in AWP RPZT 7 containing information on the status of each of the tests.

According to the principle of operation, the stand is a hardware and software that includes a computing system that operates in real time with the connection of the test object (IMS equipment) via standard lines of information interaction. Each computing tool in the system has its own purpose, determined by the software installed on it and its hardware.
