Description

The proposed utility model relates to computer technology, namely, devices for debugging, health monitoring and pairing of shipboard digital 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. Moreover, very often physical protocols of exchange between different systems on the same object are performed of the same type. Usually these are multiplex channels (two-channel redundant, or single-channel non-redundant), as well as channels of a local network, for example, Ethernet. Often these channels are supplemented by channels for the exchange of discrete signals using modules of digital input-output (DAC).

The well-known IR-60 simulator for debugging ship digital computing systems according to the certificate of the Russian Federation No. 6251 for a utility model, IPC G06F 11/28, publication March 16, 1998. The simulator contains a microprocessor module connected via an interface line to a video adapter, the output of which is connected to an indication unit as well as with a digital input-output device, the inputs of which are connected to a source data input unit, and with an analog exchange unit based on a digital input-output device connected to an amplifier unit, input-output the odes of which form the inputs and outputs of the analog signals of the simulator. The input-output of the serial port of the microprocessor module is connected to a digital exchange unit, the inputs and outputs of which form the digital inputs and outputs of the simulator.

The disadvantage of the well-known IR-60 simulator is limited functionality, in particular, the inability to simulate exchange with various external systems, the limitations of the ability to output data obtained during operation, and the complexity of software modifications.

The closest analogue adopted for the prototype of the proposed utility model is a comprehensive simulator for testing the ship control system according to the RF patent No. 78590 for utility model, IPC G06F 11/28, publication November 27, 2008

The prototype simulator contains two electronic computers (computers) integrated into the network through a local area network switch and a server system unit, to which a data input unit and an indication unit are connected. The first and second multiplex channel adapters and a pulse-frequency code generator are connected to the first computer via a system interface highway (SIM), and the first and second adapters of asynchronous serial redundant exchange channels and a two-channel adapter of serial synchronous exchange channels are connected to the second computer through a second SIM. All adapters connected to the first and second SIM are connected to a passive transient device, and the pulse-frequency code driver is connected to it via a pulse amplifier, and the two-channel serial synchronous channel adapter is connected to the transition device via a serial interface converter.

The main disadvantage of the prototype is the large weight and size characteristics of the simulator.

The presence of three computing nodes connected by a local network increases the size of the simulator and does not allow it to be used as a mobile tool for debugging the interaction of systems at an object, which usually starts with pairing, when each system is connected in series to each of the interfaced systems. In this case, the following difficulties arise:

- the systems are manufactured and arrive at the facility unevenly; therefore, often due to the lack of a separate system, the development of the entire complex of systems is delayed;

- with insufficiently developed systems software, because of their complexity, it can be dangerous to directly connect the systems to each other;

- the object must have a standard to verify the correct exchange.

The technical result of the utility model is to ensure the debugging of communication channels in the absence of a complete set of equipment for a digital control system with the possibility of using a simulator as a reference tool when pairing mating systems on an object.

The essence of the utility model is that in the simulator for debugging information channels of communication of digital control systems, which contains a data input unit, an indication unit and an electronic computer connected via a system interface line to the first and second multiplex channel adapters, a two-channel redundant adapter is additionally introduced multiplex channels and a digital input-output module connected to the system interface line of the electronic computer, and also introduced There are two devices for remote switching of multiplex channels, the external inputs and outputs of which form the first and second inputs and outputs of the multiplex channels of the simulator, the first internal inputs and outputs of the devices for remote switching of multiplex channels are connected respectively to the main input-output and the backup input-output of a two-channel redundant multiplex adapter channels, their second inputs and outputs are connected respectively to the first and second adapters of multiplex channels, and the control inputs are are dined with the first and second outputs of the digital input-output module, the outputs of which are from third to n and the inputs from first to n form the outputs and inputs of the simulator for transmitting and receiving discrete signals, in addition, the electronic computer is designed as a laptop computer based on single-board electronic computer to which the data input unit and the display unit are connected.

The essence of the utility model is illustrated by a drawing of a structural diagram of a simulator, on which are indicated:

1 - simulator

2 - electronic computer

3 - data input unit,

4 - display unit,

5 - two-channel redundant multiplex channel adapter,

6, 7 - the first and second adapters of multiplex channels,

8 - digital input-output module,

9 - DC power source,

10, 11 - the first and second devices for remote switching of multiplex channels,

12 - system interface bus, made in the form of an ISA, PCI or VME.

As shown in the drawing, the simulator 1 contains a computer 2, which is directly connected to the data input unit 3 and the display unit 4 and connected via SIM 12 to a two-channel redundant multiplex channel adapter 5, to the first and second single-channel multiplex channel adapters 6 and 7, and to the module 8 digital input-output, the power input of which is connected to a source of 9 DC power.

Computer 2 is made in the form of a laptop computer on the basis of a single-board computer, which contains a processor, a system interface bus, a video controller, operational and long-term storage devices, serial and parallel interface adapters, a local area network adapter, flexible and hard magnetic disk drive adapters, and a keyboard interface adapter.

In addition, the simulator 1 includes two devices 10, 11 for remote switching of multiplex channels, each of which is a switching device based on a DC relay controlled by the signals of the digital input-output module 7. The external inputs and outputs of the devices 10, 11 form the first and second inputs and outputs of the multiplex channels of the simulator 1 and are used to connect the mating multiplex channels of the processed digital computing system. The first internal inputs and outputs of the multiplex remote switching devices 10, 11 are connected respectively to the main input-output and the backup input-output of a two-channel redundant multiplex channel adapter 5, the second internal inputs and outputs of the devices 10, 11 are connected to the first and second adapters 6 and 7, respectively multiplex channels, and the control inputs are connected to the first and second outputs of the digital input-output module 7, the outputs from the third to n of which form the simulator outputs for transmitting discrete signals catch and the inputs form the inputs of the first to n simulator for receiving a discrete signal fulfills system.

Mobile simulator 1 operates as follows.

Before starting work, using the data input unit 3 and display unit 4, a simulator self-test mode or an operating mode is set.

In the self-test mode, the status of the adapters 5, 6, 7 of the multiplex channels and the digital input-output module 8 are connected, connected via a system interface line 12 to a computer 2. The results of the survey are displayed on the screen of the display unit 4 in the form of diagrams with the allocation of faulty elements.

In operating mode, a list of systems is displayed on the screen of display unit 4, the interaction with which is worked out using a mobile simulator. This can be, in particular, a navigation complex, a combat information and control system (CIUS), an accurate time system, a communication system, a radar system, a fire control system, a mast-lifting device. The operator using the manipulator of the data input unit 3 selects one of the systems, the interaction with which is checked or worked out in this debugging cycle.

Systems interconnected by a multiplex channel, depending on the purpose of the system, can use various types of channels. So, the navigation complex and the time system use, as a rule, two independent channels, since a break in receiving information can lead to unacceptable errors. BIUS and firing control systems use a redundant multiplex channel with the ability to switch to a backup channel in the event of a failure, and communication systems and a radar system can use a single-wire channel with the possibility of duplicating information in case of error.

Depending on the type of the selected system, a corresponding signal is sent to the control inputs of the devices 10, 11 for remote multiplex channel switching through the digital input-output module 8, through which redundant or independent multiplex channels are connected to the outputs of devices 10, 11 (and the outputs of simulator 1). If the complex is connected with the system being worked out by one of the types of multiplex channels, then it is connected to the inputs / outputs of devices 10, 11, and if by discrete input-output signals, then to the corresponding input-outputs of the digital input-output module 8.

Further use of the simulator is determined by which system is connected to the mobile simulator and in which direction the information arrays are transmitted. For a navigation complex, an accurate time system, a radar complex, the system being worked out is a consumer of information. For a fire control system - provides target designation data. For a communication system and a CIUS, it issues and receives information arrays, and for a lifting mast device it issues and receives discrete signals.

Using the data input unit 3, the operator enters outgoing information arrays that are displayed on the screen of the display unit 4. For the firing control system, these are target designation data, for the CIUS - the coordinates and parameters of the movement of targets, for the communication system - the transmitted messages. This data through the adapters 5, 6, 7 of the multiplex channels and the device 10, 11 remote switching come in complexes associated with the system being worked out. The incoming information arrays come in the opposite direction through devices 10, 11, adapters 5, 6, 7 of the multiplex channels and are displayed on the screen of the display unit 4. In the process of debugging and pairing, the information arrays displayed on the display unit 4 of the mobile simulator and on the display unit of the mating system are compared with each other. The identity of the arrays indicates proper interaction.

After installing the system at the facility, a mobile simulator can be used as a reference tool for debugging the interaction of paired systems. At the same time, regular communication channels are switched off, information arrays are set using the simulator, they are inserted into the interfaced systems and the channel is checked for correct operation according to the information in the communication protocol of the interfaced systems.

Thus, the proposed mobile simulator provides reproduction of the reception and delivery of information on any processed channel, simulating the functioning of the developed complex in real time, which improves the operational reliability of the complex.

The industrial applicability of the utility model is determined by the fact that the proposed simulator can be manufactured according to the description and drawing based on well-known components and well-known technological equipment and used in testing ship information and control systems for various purposes.
