Description

The invention relates to simulators and can be used to develop practical skills for students to work with an aviation multifunctional indicator.

There is a well-known training simulator (Kostin, P.S. Software-modeling complex for semi-natural simulation of the dynamics of a maneuverable aircraft / P.S. Kostin, Yu.O. Vereshchagin, V.A. Voloshin // Journal "Proceedings of MAI". 2015. No. 81 . P. 1-30), containing a device for displaying flight and navigation information of a software-simulating complex for semi-natural simulation of the dynamics of a maneuverable aircraft, taken as an analogue and consisting of a central monitor connected to a personal computer on which a program is installed that displays a simulation model of the information field aviation multifunctional indicators.

However, the well-known training simulator based on a conventional monitor and a personal computer with a program has the disadvantage that it is impossible to change the displayed information frames due to the lack of implementation of the “man-machine” interface (there are no controls on the display frame - buttons, encoders, etc. ), and therefore, when using such a training simulator in training sessions, it is impossible to develop the necessary practical skills for working with an aviation multifunctional indicator, namely, changing personnel, entering data, changing display modes, which is very important for improving the quality of training of flight personnel.

The closest to the claimed invention in technical essence and accepted by the author as a prototype is an aviation multifunctional indicator (RF patent No. RU 2181093C1, authors G.I. Aleksandrov and others), containing a liquid crystal LCD screen, a block of LCD parameter sensors and OBD controls, a block executive devices BIU, device for combining and overlaying images USNI, control unit for operating modes BUR, input-output-information exchange control adapter AVVU, graphic processor device UGP, image smoothing device USI, source data block BID, radar weather information adapter ARM, information adapter relief of the earth's surface ARZ, television information adapter ATI, command and information exchange highway MKIO, background image video information highway MVFI, video information highway of the graphics processor MVGP.

However, the well-known aviation multifunctional indicator cannot be used as a simulator without additional equipment, which includes on-board interacting devices BVU and ground interacting devices NVU, providing power supply and issuing information signals for the display. In addition, the known aviation multifunctional indicator includes a large number of devices, the presence of which is not necessary for training flight personnel to work with the aviation multifunctional indicator. Because of this, the well-known aviation multifunctional indicator, when used as a simulator, has the following disadvantages: low weight and size indicators, high cost and low reliability.

The purpose of the invention is to implement an intelligent color indicator of the “man-machine” interface in a training simulator, as well as to improve weight and size indicators, reduce cost and increase reliability.

The technical result of the invention is the creation of a training simulator of an intelligent color indicator (TIICI), the implementation of a “man-machine” interface in it, improving weight and size indicators, reducing cost and increasing reliability.

The technical result is achieved by the fact that the proposed TIITS, containing a personal computer (PC) with a program that simulates the operation of the information field of the indicator, a housing on which the display and video card are rigidly fixed, a video cable, a power supply, additionally contains a USB cable, twenty-eight buttons, and a controller buttons, twenty-eight resistors connected in series to form a voltage divider, each resistor having a first and a second pin, the first pin of the first resistor connected to the positive pin of the voltage divider power supply, the second pin of each resistor except the last one connected to the first pin of the next resistor , and the second contact of the last resistor is connected to the negative power wire of the voltage divider, each button has first and second contacts, which close when the button is pressed and open when the button is not pressed, the first contact of the corresponding button is connected to the first contact of each resistor, and the second contacts of all buttons are interconnected and connected to the analog input of the button controller, connected via a USB cable to a personal computer.

The proposed TIITS invention contains a housing 1, a display 2, a video card 3, resistors 4 (28 pcs.), buttons 5 (28 pcs.), a button controller 6, a video cable 7, a power supply 8, a USB cable 9, a personal computer 10.

In fig. 1 shows a general view of the proposed invention TIITSI (without PC), Fig. 2 shows its electrical diagram, Fig. Figure 3 shows a diagram of connecting the TIITS display to a PC.

Housing 1 of the proposed TIITS is designed for fastening all elements, their exact location, as well as placing the TIITS in the classroom (using a stand on a table or using fasteners on a mock-up of an aircraft cabin). The display 2, video card 3, resistors 4, buttons 5, button controller 6 are rigidly fixed in housing 1. Video cable 7 (for example, VGA or HDMI) is designed to connect video card 3 to the video output of PC 10 (Fig. 1, 2, 3). The power supply 8 is designed to provide the necessary level of low-level DC voltage (for example, 12 V, as shown in Fig. 2) to the video card 3, to which the display 2 is connected, from an AC source with a voltage of 220 V 50 Hz. USB cable 9 is designed to connect the button controller 6 to the PC USB port 10 to transmit information about the position of the buttons 5.

All resistors 4 (R1-R28 in Fig. 2) have the same resistance; they are connected in series and form a voltage divider. Each resistor has two contacts (first and second), with the first contact of the first resistor connected to the positive contact of the voltage divider power supply (5 V in Fig. 2), the second contact of each resistor, except the last one, connected to the first contact of the next resistor, and the second contact of the last resistor is connected to the negative power wire of the voltage divider (GND in Fig. 2). Each button 5 has two contacts (first and second), which close when the button is pressed and open when the button 5 is not pressed. The first contact of the corresponding button 5 is connected to the first contact of each resistor 4, and the second contacts of all buttons 5 are connected between themselves and connected to the analog input of the button controller 6 (contact AO in Fig. 2). The number of resistors 4 (R1-R28) is equal to the number of buttons 5 (K1-K28), as shown in the TIITS electrical diagram (Fig. 2), each button 5 has its own resistor 4, the first contact of which is connected to the first contact of the corresponding button 5. The number of buttons 5 and their location on the body 1 are made in accordance with a real intelligent color indicator, in which 28 buttons are located on the frame of the display 2: 8 on top, 8 on bottom, 6 on the left and 6 on the right.

Due to the fact that each of the buttons 5 (K1-K28) is connected to the first contact of the corresponding resistor 4, and the connection of all resistors 4 in the voltage divider is made in series, when each of the buttons 5 is pressed, a signal of a certain voltage level is generated between the negative power contact a voltage divider (GND contact in Fig. 2) and an analog input of the button controller 6 (AO contact in Fig. 2). The possible analog input voltage range is 0 to 5 VDC. The analog-to-digital converter in the button controller 6 measures this voltage and converts it into a code, which is an integer in the range from 0 to 1024, i.e. the measurement resolution is 5/1024=0.0049 V, while a voltage of 0 V corresponds to code 0, and a voltage of 5 V corresponds to code 1024. When you press each button 5, its own code value is generated, corresponding to the voltage at the first contact of that voltage divider resistor 4, to which the first contact of the corresponding button 5 is connected. With this connection scheme, simultaneous pressing of two or more buttons 5 is not allowed, which is not critical and corresponds to normal operation with the training simulator.

In the button controller 6, the number of the pressed button 5 (one of the buttons K1-K28) is determined, depending on the voltage value supplied to the analog input of the button controller 6. When each of the buttons 5 is pressed, a voltage is generated at the analog input of the button controller 6, the level of which is to one of 29 subranges (28 subranges corresponding to the pressed position of one of the buttons 5 (K1-K28) and 1 subrange corresponding to the non-pressed position of all buttons 5). In the button controller 6, the voltage level at the analog input is converted into the number of the pressed button 5 using an algorithm that determines the number of the subrange in which the voltage level falls (if no button is pressed, this number is 0). Information about the number of the pressed button 5 is transmitted from the button controller 6 via a USB cable 9 to the PC 10, on which a program is installed, in which this information is received and used to change the display in accordance with the algorithms of the program.

Operation of TIITS is possible only with PC 10 (having a video output and a USB port), on which a program is installed that receives information from the button controller 6 about the number of the pressed button 5 and simulates the operation of the indicator information field.

TIICI works as follows. When a voltage of 220 V 50 Hz is applied to the input of the power supply 8, a low-level DC voltage (for example, 12 V) is generated at the output of the power supply 8 (for example, 12 V) to power the video card 3 and display 2, which then come into operation. After connecting video card 3 via video cable 7 to the video output of PC 10 (Fig. 3), on which a program simulating the operation of the information field is running, the initial indication is displayed on display 2. When connecting the button controller 6 via a USB cable 9 to the USB port in PC 10, power is provided to the voltage divider (the power source of the voltage divider is the USB port of PC 10), containing series-connected resistors 4 (R1-R28). In this case, the button controller 6 comes into operation, which determines the number of the pressed button 5 and transmits it to the PC 10 via USB cable 9. In the program that simulates the operation of the information field, depending on the number of the pressed button 5, the indication transmitted via video cable 7 to video card 3 and displayed on display 2, in accordance with the programmed algorithms. The content of information frames and algorithms for changing the indication on the information field of the indicator are programmed in a developed program installed on PC 10.

Disadvantage of the well-known training simulator (Kostin, P.S. Software-modeling complex for semi-natural simulation of the dynamics of a maneuverable aircraft / P.S. Kostin, Yu.O. Vereshchagin, V.A. Voloshin // Journal "Proceedings of MAI". 2015. No. 81. P. 1-30), consisting in the absence of implementation of the “man-machine” interface, is eliminated by the fact that the proposed TIITS contains a USB cable, twenty-eight buttons, a button controller, twenty-eight resistors connected in series, forming a voltage divider, while each resistor has a first and a second terminal, the first terminal of the first resistor is connected to the positive terminal of the voltage divider power supply, the second terminal of each resistor except the last is connected to the first terminal of the next resistor, and the second terminal of the last resistor is connected to the negative terminal of the voltage divider power supply, each the button has first and second contacts, which close when the button is pressed and open when the button is not pressed, the first contact of each resistor is connected to the first contact of the corresponding button, and the second contacts of all buttons are interconnected and connected to the analog input of the button controller, connected via USB -cable to PC.

The disadvantage of the prototype, which consists in the impossibility of using it as a technical training tool without additional equipment, which includes on-board interacting devices of the NVU and ground-based interacting devices of the NVU, providing power supply and issuing information signals for display, is eliminated by the fact that in the proposed TIITS, instead of the NVU and NVU in The power supply is used as the power source for the display; the USB port of the PC is used as the power source for the voltage divider formed by resistors (R1-R28), to which the voltage divider is connected via a USB cable; interacting devices NVU uses a PC with a program that simulates the operation of the information field, information from which is displayed on the display via a video cable.

The disadvantage of the prototype, which is that it has low weight and dimensions, high cost and low reliability, is eliminated by the fact that in the proposed TIITS, instead of additional devices that are contained in the well-known aviation multifunction indicator, but the presence of which is not necessary for training flight crews to operate with an aviation multifunctional indicator, namely: a device for combining and superimposing images USNI, a control unit for operating modes BUR, an input-output adapter for information exchange control AVVU, a graphic processor device UGP, an image smoothing device USI, a block of initial data BID, an adapter for radar weather information AWP , information adapter about the relief of the earth's surface ARZ, television information adapter ATI, command-information exchange highway MKIO, video information highway of the background image MVFI, video information highway of the graphic processor MVGP, on-board interacting devices of the BVU and ground-based interacting devices of the NVU, for the formation and delivery of the necessary information to The display uses a personal computer with a program that simulates the operation of the indicator information field.
