Description

The utility model relates to the field of computer technology and can be used as part of the on-board radio-electronic equipment of aircraft and ground equipment as a multifunctional computer for complex data processing.

A navigation device for a vehicle is known, described in DE patent No. 29619839 dated 11/14/1996, IPC G01C 21/20. The device includes a GPS device, a map display device with a mass storage device for storing maps, a computing device (for selecting a subset of map data, scaling map data, if necessary, for rotating maps and obtaining an image of a map of an area).

The disadvantages of the presented analogue is the implementation of only the functions of navigation and the formation of cartographic information without the possibility of simultaneous formation of two independent output channels of video information and, as a result, limited functionality.

The closest analogue, taken as a prototype, is the on-board computer described in the patent of the Russian Federation No. 191274 dated 04/22/2019, IPC G06F 15/16. The on-board computer includes a microcomputer for processing information, as well as adapters for information exchange channels and an adapter for a one-time command device, made in the form of an external interface device.

The disadvantages of this prototype are the inability to generate and display information in graphical form.

The technical result consists in expanding the functionality by generating and issuing information both in graphical form as part of video information and in the form of a serial binary code, as well as storing information necessary for the operation of the vehicle.

The specified technical result is achieved due to the fact that the multifunctional on-board computer contains a data processing unit connected by digital interfaces to a data storage unit, an information receiving unit and an information output unit, the data processing unit consists of a data processing unit connected via a local bus and a graphic information generation unit , and the multifunctional onboard computer contains a navigation data block connected to the information processing module, as well as an output graphic information block connected via a local bus to the graphic information generation module, consisting of the first output graphic information module and the second output graphic information module.

In FIG. 1 shows a block diagram of a multifunctional on-board computer, where:

1 - data processing unit;

2 - information processing module;

3 - module for generating graphic information;

4 - data storage unit;

5 - navigation data block;

6 - block receiving information;

7 - block issuing information;

8 - block output graphic information;

9 - the first module of output graphic information;

10 - the second module of the output graphic information;

11 - external systems.

The multifunctional on-board computer has two channels for outputting graphic information and contains a data processing unit 1, consisting of an information processing module 2 and a graphic information generation module connected by a high-speed local bus, an output graphic information block 8, consisting of the first output graphic information module 9 and the second module output graphic information 10, each of which is directly connected to the module for generating graphic information 3 by a high-speed local bus, as well as a data storage unit 4, a navigation data unit 5, an information receiving unit 6 and an information output unit 7 connected to the data processing module 2 with using digital communication interfaces.

The multifunctional onboard computer works as follows.

During the initial installation on board the multifunctional onboard computer, operational documentation in electronic form, databases of cartographic, relief and aeronautical information in binary format, necessary to complete the current flight task, are entered into its data storage unit 4.

During the operation of the multifunctional on-board computer, information about the current location, speed and direction of movement, the structure of the flight plan and the parameters of movement along the flight path, the radar image scanned in the direction of flight, and control commands in digital form from external on-board systems 11 are sent to the information receiving unit 6 In the information receiving unit 6, information signals are converted into internal data structures of the multifunctional onboard computer and transmitted to the information processing module 2.

In the absence of information from external on-board systems 11 about the current location, speed and direction of movement, the navigation data block 5 determines the navigation parameters of the object, such as the current coordinates of the place, the components of ground speed relative to the ground and the ground angle from radio signals received by the navigation antenna from navigation spacecraft global navigation satellite systems GLONASS, GPS, GALILEO and transmits to the information processing module 2.

The information processing module 2 builds nine rectangular sections in the RAM of the device, one of which is the main rendered, and eight other non-visualized sections along the perimeter of the main one, intended for the first module of the output graphic information 9 or the second module of the output graphic information 10. Each section corresponds to the size of the generated output frame of video information. In the information processing module 2, an output information data structure is formed containing information about the current location, speed and direction of movement defined in the navigation data block 5, information messages about the reliability of information coming from the information receiving unit 6, about a dangerous approach to the earth's surface or an artificial an obstacle. After processing the specified information in the information processing module 2, the data is transmitted to the module for generating graphic information 3.

Based on the received navigation information, control commands and information layers activated by the operator, the graphic information generation module 3 analyzes the presence of the necessary sections for building a frame. The missing information is unloaded from the data storage unit 4 and, after conversion in the data processing module 2, is added to the previously prepared information. Further, by layer-by-layer overlay of graphic images related to different types of information, the graphic information generation module 3 generates graphic images of information frames and transmits them to the output graphic information block 8, where, after conversion into a video signal, the first output graphic information module 9 and the second output graphic information module 10 this information is sent to consumers.

The output information block 7 converts the data structure of the output information generated in the information processing module 2 into a serial digital code for issuance to consumers.

Thus, the multifunctional on-board computer provides the possibility of generating and issuing graphic information, and also allows you to store all the necessary information for the operation of the vehicle.
