Description

The invention relates to the field of telecommunications of mobile objects and can be used to implement information exchange between aircraft (LA) moving at high speed.

The hardware-software complex for data exchange is intended for installation on aircraft. One of its components is an on-board computer system, which functionally forms an on-board computer system (BWS).

The structure of the BVS is considered as a hardware implementation of the architecture, performed with a focus on a specific application. Currently, the construction of aircraft avionics (avionics) of aircraft is characterized by a long development period, often reaching 10-15 years, and high costs for the creation of individual subsystems and the complex as a whole. To solve each problem, as a rule, its own modification of the onboard computer is developed, and in the subsystems of the complex, even with almost the same required resources, machines with different architectures created by different developers are used. The issues of unification of the means of computer technology used to build the military-technical complex are resolved unacceptably slowly. Such an approach to the construction of a military vehicle in combination with the principles used to build the structure of both a separate on-board computer and the system as a whole leads to an increase in the cost of hardware and software, and to an increase in operating costs. Moreover, on-board computers and a computer system are often morally obsolete already in the process of development [1].

Such principles of the organization of BVS have exhausted almost all of their capabilities. Their main qualities, which fundamentally changed at one time approaches to the integration of on-board equipment and stimulated the development of digital avionics, ceased to meet the ever-increasing requirements for avionics [1].

Modern trends in the development of BVS are:

- the use of unified high-performance on-board computing modules;

- minimization of the amount of computing tools;

- software implementation of the functionality of different subsystems of the aircraft.

Closest to the claimed invention is the manager

hardware-software complex for exchanging data of a mobile object described in the patent for utility model No. 38433 [2] and taken as a prototype.

The prototype relates to data exchange systems between aircraft and is designed to provide stable communication in a constantly and at a high speed changing structure of a communication system that uses different ranges depending on the current situation when organizing communication channels for exchanging information, taking into account the distance between interacting objects. The hardware and software complex of the prototype includes: an on-board computer complex, consisting of four system units and two interface units mounted on a common frame, an analog-digital display, a roll-telegraph apparatus, data transmission equipment (ADF), radio communication equipment (AR), water data device (ATC) [2].

The prototype has the following disadvantages:

1. A large number of computing units leads to increased weight and size characteristics and increased power consumption of the hardware-software complex. For each set of tasks implemented by software modules, a separate computing unit is allocated. In total, the complex uses 4 system units mounted on a common frame and interacting with each other.

2. The use of specialized interface units leads to increased weight and size characteristics, increased power consumption and a low level of unification.

3. A large number of technical means leads to a decrease in reliability indicators and an increase in the cost of the complex.

4. The use of low-speed interfaces for the information exchange of computing units with peripheral equipment, data transmission equipment, and communication facilities results in low performance of the hardware-software complex.

5. The presence of a roll telegraph apparatus in the complex also leads to increased mass and size characteristics and increased energy consumption.

6. There is no possibility to transmit via communication channels messages from external sources / consumers of information (VIPI).

Thus, the main technical problem to be solved by the claimed invention is aimed at increasing the level of unification, reliability and performance of the hardware-software complex, reducing its cost and overall dimensions, reducing the complexity of operating data exchange tools (systems), as well as expanding the scope of functional application .

The specified technical result is achieved by the fact that in the hardware-software complex for exchanging data of a mobile object, consisting of an on-board computer complex connected by two-way communications to a graphic display (DG), data input device (ATC) and data transmission equipment (ADF), which has a separate an interface for exchanging data with radio communication equipment (AR), an on-board computer system that provides interaction with the ADF, AR, DG, ATC, is connected by two-way communications to an external source / consumer inf Formation and is an integrated computing unit with its constituent controllers of unified information interfaces and a software module for telegraph communication.

The drawing shows a structural diagram of the proposed hardware-software complex, where it is indicated:

1 - integrated computing unit;

2 - graphic display;

3 - data input device;

4 - data transmission equipment;

5 - radio communication equipment;

6 - external source / consumer of information.

The main difference between the proposed hardware and software complex for exchanging data from a mobile object from the prototype is that its on-board computer complex is one integrated computing unit with its components: a software module for telegraph communication, controllers for unified Ethernet information interfaces, USB, SVGA, GOST 18977-79 and GOST RV 52070-2003, which allow interacting with the ADF for exchanging messages over communication channels, with the DG to display to the operator information, with ATC for the operator to dial messages issued to the ADF when transmitting via communication channels, with AR to configure communication equipment, with VIP to receive messages from the information source that need to be sent to the channel, and to issue information received from the channel to the consumer, as well as with an external storage medium for receiving planned data prepared in advance and for outputting information recorded during the operation of the hardware-software complex. An integrated computing unit is not only a source / receiver of information, but also an intermediate link in a communication channel that performs the functions of processing and transmitting data generated in external sources of information or intended for external consumers of information.

The hardware-software complex works as follows. Having received a message generated by an external information source 6 or typed on a data input device 3, the integrated computing unit 1 determines the need for its transmission via communication channels and, following the procedures of the session, transport, network and channel levels, issues the generated information packet to the ADF 4. APD 4 It carries out cryptographic encryption and error-correcting encoding of the information packet, after which it sends the received code to AP 5 for delivery to the radio channel.

Upon receipt of a codegram received over the air from the AP 5, the APD 4 removes the error-correcting code and cryptographic encryption and transfers the received information packet to the integrated computing unit 1. With the received information package, the integrated computing unit 1 performs the channel, network, transport, and session levels, and After analyzing the address information of the received message, it issues it to an external source / consumer of information 6 or to a graphic display 2.

The claimed invention in comparison with the prototype allows to improve the following characteristics of the hardware-software complex for data exchange of a mobile object:

1. Decrease in weight and size characteristics, reduction in energy consumption and cost due to the use of one integrated computing unit to solve all problems of ensuring the exchange of information and due to the software implementation of the functions of a roll telegraph apparatus;

2. Ensuring a high level of unification through the use of unified information exchange interfaces of the integrated computing unit with peripheral equipment, ADF and communications;

3. Expanding the scope of functional application by realizing the possibility of transmitting VIPI messages over communication channels.

4. Reducing the time for maintenance of the hardware and software complex due to a decrease in the number of hardware included in the complex.

The claimed hardware and software complex for exchanging data from a mobile object is designed to implement the functions of the channel, network, transport, and partially session levels of the reference basic model of open systems [3], as well as to control communication equipment taking into account the specifics of aviation communications, namely, a constant and rapidly changing position in spacecraft.
