Description

The proposed utility model relates to computer technology, namely, to devices for debugging and monitoring the health of ship information-control systems, in particular, ship weapon control systems.

Modern information management systems are associated with many external systems, with each of which exchange data in accordance with its own exchange protocol. Therefore, for debugging, adjusting and commissioning the system, it is necessary to reproduce in real time all the input and output signal flows, since external systems operate independently of each other. On the other hand, information flows are interconnected, because Information from external systems, such as, for example, sonar and radar stations, comes from a single external environment, and data from the navigation complex are associated with the ship’s own movement and affect the data of external systems.

Thus, only simultaneous real-time simulation of the entire stream of input and output data from external systems allows reliable work out of the information-control system and debugging the tasks that the system solves.

A well-known IR-60 simulator for debugging shipboard digital control systems [1], comprising a source data input unit, a digital exchange unit and an indication unit, a microprocessor module, an adapter, an analog exchange unit and a digital input-output device, while the input-output of the microprocessor module connected to the input-output of the digital exchange unit, the group of inputs and outputs of which is a group of digital inputs and outputs of a simulator for debugging ship digital control systems, the adapter output is connected to the input of the display unit, input -output of the digital input-output devices connected to the input-output of the data input, the microprocessor module, the adapter unit exchange analog and the digital input-output ports connected with its trunk interface and the inputs-outputs

analog exchange units are analog inputs and outputs of the simulator for debugging shipboard digital control systems.

The disadvantages of the known device are the limited functionality of the simulator, in particular, the inability to simulate control systems of various types, the limited ability to output data obtained during operation, the complexity of modifying the software of the simulator.

The closest analogue adopted for the prototype of the proposed utility model is a control system simulator [2].

The prototype simulator comprises a first electronic computer (PC) connected via a first system interface highway (SIM) to a digital exchange unit, an analog exchange unit, a multiplex communication channel adapter, a first discrete input unit and a first discrete output unit, a second computer connected by means of a second SIM with a second discrete input unit and a second discrete output unit, as well as a control panel including an indication unit, the input of which is connected to the corresponding output of the second about the discrete output unit, and the data input unit, the first output of which is connected to the corresponding input of the second discrete input unit, the second output is connected to the corresponding input of the fault simulation unit, and the third output is connected to the corresponding input of the passive transition switching device, the corresponding internal inputs and outputs of which connected to the unit simulating faults, and the external inputs / outputs form the inputs / outputs of the communication channels with the developed ship control system.

The disadvantage of the prototype is the limited functionality of the simulator, in particular, the inability to simultaneously simulate in real time the exchange of information between the developed ship control system and all external systems, for example, radar and sonar stations, which reduces the reliability of testing the control system.

The solved problem of the utility model is to expand the functionality of the simulator to increase the reliability of testing the ship control system by providing the possibility of simultaneous

simulation of real-time information exchange between the system being worked out and all external systems.

23 is a passive transition switching device designed to connect simulated communication channels with ship support systems (navigation system, lag, radar station, combat information management system, sonar stations) to the standard connectors of the tested ship weapon control system.

As shown in the drawing of the structural diagram of the simulator, the input / output unit 2 (made, for example, in the form of a keyboard) and the display unit 4 (monitor) forming the control panel 2 are connected to the server system unit 1, which is connected through the switch 13 of the local area network with the first and second computers 5 and 14.

The first computer 5 is connected via the first SIM 12 to the first and second adapters 6, 7 of the multiplex communication channel and to the driver 8 of a pulse code, which is connected via a pulse amplifier 9 to the third input-output of a passive transient switching device 23, the first and second inputs and outputs of which connected to adapters 6, 7 multiplex communication channels.

Input 19 and output 20 of the computer 14 are used to connect a technological keyboard and a technological monitor.

The eighth and ninth inputs and outputs of the passive transient switching device 23 form the inputs and outputs of the simulated multiplex communication channels with the navigation system, the tenth input and output forms the input and output of a simulated number-pulse communication channel with a lag, the eleventh and twelfth inputs and outputs form the inputs and outputs of the simulated serial asynchronous communication channels with a radar station and a combat information-control system, and the thirteenth and fourteenth are the inputs and outputs of simulated serial synchronous channels of exchange with sonar stations.

A comprehensive simulator of external systems works as follows.

Before starting work on the control panel 4 of the simulator sets the self-test mode or operating mode, which can be static or dynamic.

In the operating mode, the operator is typed using the data input unit 2, and the corresponding information arrays associated with the simulated external systems are monitored using the indication unit 3. For a simulated lag, these are components of the ship’s speed, for a simulated navigation system, heading, speed, board and keel angles, ship coordinates, for a simulated combat information-control system, these are not only target parameters, but also control commands,

and for simulated radar and sonar stations - the coordinates and parameters of the movement of targets.

In addition, for all simulated external systems, their operation modes and a set of simulated faults are set. So, for example, for radar and sonar stations, the scales used and the power of the transmitted signals, the accuracy of determining the coordinates and motion parameters of the targets can be set.

Entered information arrays in a static operating mode are transmitted with a fixed low frequency via a local area network (Ethernet) through a LAN switch 13 to the first and second computers 5 and 14.

In accordance with the programs recorded in long-term storage devices, these arrays are converted into data packets corresponding to the protocols of the exchange of external systems with the developed ship weapon control system.

These packets are formed with a high frequency and are transmitted for the simulated navigation complex to adapters 5, 6 of multiplexed communication channels, operating simultaneously and independently of each other. Information arrays are transmitted in accordance with GOST 26705.82-87 (MIL-STD - 583).

For the simulated lag, a speed value is transmitted to the shaper 8 of the number-pulse code, which is converted by it into a number-pulse sequence.

For the simulated radar station and the combat information-control system, byte asynchronous streams are formed, transmitted via adapters 14, 15 of the reserved serial asynchronous exchange channels in accordance with the RS-422 standard.

For two simulated sonar stations, two byte synchronous streams are formed in accordance with the RS-232 standard, which are transmitted through a two-channel adapter 17 synchronous communication channels.

The generated signals, if necessary, are amplified: the signals from the output of the shaper 8 of the pulse number code are in the pulse amplifier 9, and the signals from the outputs of the two-channel adapter 17 are in the converters 21, 22 of the serial interface format.

After the necessary amplification, signal packets simulating the corresponding external systems are transmitted through the inputs from the first to the seventh passive transient switching device 23 to its outputs from the eighth to the fourteenth and then to the corresponding inputs of the developed ship weapon control system.

The dynamic mode of the simulator differs from the static one in that in the server system unit 1, information arrays change in real time in accordance with the dynamics of the movement of targets, media, and predetermined temporary changes in the conditions of operation of external systems. In this case, the interaction between the server system unit 1 and the computer 5, 14 does not change.

Communication channels of simulated external systems with the system being worked out are bidirectional. Service packets for checking the integrity of the communication channel are received from the system under development in accordance with a given exchange protocol with a given frequency. These packets, passing through the corresponding adapters 6-8 and 15-17 and computers 5, 14, through the LAN switch 13 and the server system unit 1, go to the control panel, where they are displayed on the screen of the display unit 3, which allows the operator to decide on serviceability of the communication channel. In addition, the operator can artificially set any malfunction of any communication channel and proceed to transfer from the main channel to the backup one.

The simulator has two self-test modes: current self-test and in-depth self-test.

The mode of the current self-test is set from the control panel without changing the configuration of the simulator and while maintaining communication with the system being worked out. At the same time, from the server system unit 1 through the LAN switch 13, the state of the first computer 5 and the adapters 6-8 connected to it through the first SIM 12 are polled, as well as the second computer 14 and the adapters 15-17 connected to it via the second SIM 18 are polled. The survey results are displayed on the screen of the display unit 3 in the form of a diagram with the allocation of faulty components.

In the mode of in-depth self-testing, before its beginning, using the external connectors, the inputs and outputs are connected to each other

adapters 5, 6 multiplexed communication channels, adapters 15, 16 redundant serial asynchronous communication channels and converters 21, 22 of the format of serial interfaces. At the same time, communication with the developed ship system is broken.

After such a configuration change of the simulator, the in-depth self-test mode is set from the control panel 4 and through the local network switch 13 the adapters 6, 7 and the former 8 are interrogated, connected to the computer 5 via SIM 12 and the adapters 15, 16, 17, connected to the computer 14 are interrogated SIM 18. The test results are displayed on the screen of the display unit 3 with the allocation of faulty simulator devices.

Autonomous self-test mode is used for autonomous tests and passing tests.

When debugging the simulator, its components can be configured autonomously, while the technological keyboard blocks are connected to inputs 10 and 19, and technological monitors are connected to outputs 11 and 20.

Thus, the proposed simulator has wide functional capabilities, simultaneously reproducing in real time the signal flows from various external systems and providing control of service information packets received from the system being worked out, which allows to increase the reliability of the system and its reliability.

The industrial applicability of the utility model is determined by the fact that the proposed simulator can be made according to the description and drawing based on the known components and known technological equipment used in instrumentation, and used in the development of shipborne weapons control systems.
