Description

Remote control radio devices. The proposed utility model relates to the field of aviation instrumentation. It is intended to provide the pilot with manual control of the following radio engineering means of navigation, landing and communication:

-radionavigation system of near navigation and landing meter wavelength range - VOR (2 sets);

-radiotechnical landing system meter wavelengths - ILS (3 sets);

-radiotechnical system of near navigation and landing of the decimeter wave range - RSBN (2 sets);

-automatic radio compass - ARC (2 sets);

- airplane range finder - DME (2 sets);

- microwave landing system - MLS (3 sets);

- MB communication system - meter wavelength range (3 sets);

- DKMV communication system - decimeter wave range (2 sets).

In aircraft developed before the 1980s, each radio device was controlled by its own control panel. This required an additional crew member - radio operator (flight engineer) because it is impossible to place all remotes in an area accessible to the pilot. The mass and energy consumption of such a flight navigation system are large.

The following complex remotes are known for controlling radio-technical devices of an aircraft:

KPRTS-85 (complex remote control of radio engineering systems) 1. Control comes from the remote control in conjunction with the VSS-85 airplane navigation computer system. It was installed on TU204 and IL-96 aircraft in the KSCSPPO-204/96 flight and navigation complex. The disadvantages of this solution are that the remote control transmits a control action to the BCC, and it to the radio devices. Those. the remote does not have the ability to independently control radio devices. In the event of a BCC-85 failure, even a working KPRTS-85 loses control capabilities; a failure of the second BCC-85 leads to a complete loss of control over the settings of the radio equipment. In addition, the remote control can only be used together with the BCC-85, which limits the possibility of upgrading the flight-navigation complex and the scope of the remote control.

Integrated RTU - 4200 2 m. Collins. It contains controls (buttons), indicators (liquid crystal panel) and a specialized computing system with software recorded in read-only memory. Allows you to manage navigation and communications. An analysis of the connection diagram of this remote control (the diagram is given in the description) showed that failures leading to the loss of broadcasting of one of the remote controls result in a loss of controllability of the radio devices connected to this remote control. The description does not indicate whether the remote control software can be replaced; therefore, it can be assumed that the software is replaced in a standard way, i.e. the remote control is opened and replaced

IPC: 7 B64D 47/00

read only memory chip. This complicates the software upgrade during the operational phase.

The closest analogue of the proposed utility model to the RTU is 4200 f. Collins.

To eliminate these drawbacks, a wrench switch and an RS-232 node for communication with a computer are introduced in the proposed utility model.

A wired switch connected to the outputs of the console’s serial code, BCC and the backup input of the radio devices, with the ability to turn off the console and connect the BCC instead. This allows for any failure of one of the control panels to control all radio devices, and with a simultaneous failure of both panels to control radio devices from BCC.

The connection diagram shown in figure 1. illustrates the relationship between the control panel of radio devices, BCC and the devices themselves in a typical inclusion. In this diagram:

1 and 2 - Computer navigation system number 1 and 2, respectively;

3 and 4 - Offered utility model - control panel for radio devices number 1 and 2;

5 and 6 - The first and second sets of radio devices. Each kit includes - VOR, ILS, RSBN, ARK, OME, MLS, MB, DKMV, indicated on the diagram as radio devices. Each of these devices has the main input of the serial code A, the backup - B, and the input of a one-time switching command between A and B.

During normal operation of all devices, each of

Radio engineering devices are controlled by input A from their remote control. Those. devices from set 1 are controlled by remote control 1. In order to control devices from set 2 from remote 1, communication is established between the remote controls. Each of the remote controls transmits to its output serial code number 1 control information from the other remote and from the BCC. In the event of a malfunction of one of the controllers detected by self-monitoring, a one-time command is issued by this control panel and its radio engineering devices switch to control by input B. That is, devices from the set of the faulty remote control receive control from the second channel of the serial code of the serviceable remote control at input B. Devices from the set of the safe remote control work by receiving control from the first output of the serial code in the same way as during normal operation. It also happens if the pilot puts the switch in the “Off since the remote control, under the influence of the dial switch, will issue a one-time command to switch inputs from A to B. In case the second remote control also fails, the pilot must set the dial switch of the second remote control to “Off, the second set will switch to control from input B, control information to the inputs B will be transmitted from the BCC through the dial switch in the “Off.

It is connected for programming, at the stage of debugging software, and during maintenance.

The block diagram of the control panel of radio devices is shown in FIG. 2.

Remote control radio devices a device made in the form of a specialized computing system, consisting of:

-the front panel, which includes: control and display elements in the form of indicators 1, buttons 2, flashers 3, switches 5, switch 4 and the controller of the front panel 6;

-controller remote control, which includes a specialized computing system, consisting of: ROM 7, RAM 8, microcontroller 9, RS-232 node 10, one-time command module 11, serial code module 12 and logical block 13.

The remote works as follows:

By pressing button 2, the pilot selects a custom system. The microcontroller 9, running a program recorded in ROM 7, turns on the light of the selected system 3, displays the parameter values from RAM 8 to indicators 1. In this case, the effective value of the parameter falls on the main indicator, and the previous value on the backup. Now, by turning the dial 5, you can change the parameter value on the backup indicator, and by clicking on the button this value is declared the main one. At the same time, the values of the parameters on the primary and backup indicators will change places. This allows you to rebuild the radio system when flying along the border of the zone by pressing only one button. The microcontroller 9 writes the value of the main indicator parameter to RAM 8 and transfers it to the serial code module (PC) 12, where this value is converted into a bipolar serial code and issued to the associated radio systems. Some devices require one-time commands. For receiving and issuing one-time commands, the module of one-time commands (RK) 11 is used. Logical block 13 is needed to start the microcontroller, serves to expand the input / output ports of the microcontroller, blocks the operation of the outputs and sets the outputs of the one-time commands to the “Open when switch 4 position is OFF” position .

The RS-232 node 10 contains a level converter microcircuit connected to the microcontroller 9 and an external console connector. To change the software of the radio control panel, it is not necessary to open the panel. Programming the ROM 7 is carried out by the microcontroller 9, while the data is transmitted from the computer via the RS-232 channel 10, and all the necessary voltages are generated by its power supply.

If two consoles are installed on board the aircraft to increase the reliability of the system, the settings of the radio devices are transmitted between the consoles via the serial code channel, i.e. both remotes indicate and give the same parameters even after rebuilding one of the remotes.

radio engineering system. Those. Buttons for the most complete set are provided, but during maintenance of the remote control, it is possible to disable functions that are not used on this type of aircraft. In the same way, it is possible to set the language in which messages are displayed (Russian / English). This setting can only be made when a cable with a special jumper is connected to the remote control connector, i.e. on board the aircraft, it is locked.

Interdepartmental trials are currently completed. The Interstate Aviation Committee received a certificate of suitability for the component part number STKI-023 / 110-81KPRTS-95M-1 dated July 6, 2001. The industry produces a remote control radio devices - KPRTS-95M-1. This remote control is installed on airplanes: TU-214; BE-200; IL-96.
