Description

The control system for aviation weapons of destruction (ASA) refers to on-board equipment and is designed to control the preparation and use of existing and promising types of ASA used on an aircraft (LA).

A known weapon control system of an aircraft, containing hardware, which includes a matching unit and logic, emergency unloading unit, information conversion unit and executive units (RF patent No. 2249543, IPC7 B64D 7/00, F41F 3/06).

In this system, an information channel is used for communication with the ASP, transmitting targeting signals for homing heads in the form of one-time commands, target parameters and altitude and speed parameters of the carrier from the on-board equipment complex through the matching and logic unit and the information conversion unit on the ASP, in case of failure of which the system loses the ability to manage and use TSA in normal mode.

A known control system for aviation weapons, containing a controller of energy and information channels and interface units, the controller is connected via an intersystem multiplex data transmission channel (MKPD) with a complex of on-board equipment (KBO), through a local MKPD - with interface blocks connected by an energy channel to TSA, separate communication lines, the controller and the interface units are connected to the aircraft power system and to the controls located in the aircraft cabin (RF patent No. 2350512, IPC B64D 7/00).

This system as the closest in technical essence and the achieved result is taken as the closest analogue (prototype).

In the known system, the failure of the controller, intersystem or local channels leads to the impossibility of the combat mission (the use of TSA), and, as a result, the effectiveness of the combat use of the aircraft decreases. In addition, when starting the TSA, interference occurs due to a “hot” disconnection of the TSA from the object, which lead to a failure in the exchange of information on the local MCPD, which leads to errors in the application of the rest of the TSA.

The technical result of the claimed invention is to increase the efficiency of combat use of aircraft by increasing the fault tolerance of the functioning of the ASP control system.

The technical result is achieved by the fact that the control system for aviation weapons containing a controller of energy and information channels and interface units, the controller is connected via an intersystem multiplex data transmission channel with a complex of on-board equipment, and through a local multiplex data transmission channel, with interface units connected by an energy with a channel with ASP, separate communication lines, the controller and interface units are connected to the aircraft power system and to the controls, position in the aircraft cabin is provided with a multiplexed data channels in TSA TSA for connection to the respective interface units, and each of the coupling units introduced additional multiplex channels for connection to interconnectors shared channel data and a corresponding data channel multiplex transmission in TSA.

The drawing shows a structural diagram of an ASP control system.

The controller 1 of the energy and information channels, which is a digital computer, is connected via an intersystem MKPD 2, implemented in accordance with GOST R 52070-2003, with a BWC, for example, with a satellite information receiver, with a target designation sensor from a radar, an optical target designation sensor. Interface blocks 3 are connected to the intersystem MKPD 2, each of the interface blocks 3 consists of an interface module with enhanced functionality due to the introduction of additional multiplex data channels and a power switching module. For the implementation of the interface module, well-known technical solutions for constructing devices that provide exchange according to the MCPD can be used, for example, a computing module based on the N1806VM2bKO.346.456TU microprocessor, MKIO N1582VZh3-0168, N1582VZh3-0213 IRVZh.430102.003TU controllers, amplifiers 852IP1P AEYT.43123 transformer TIL3V AGO.472105.TU.

Energy channel 4 is designed to connect supply voltages to the TSA, issue and receive signals from the TSA in the form of “+27 V”, “housing”, “open”, as well as transmit target signals for the TSA, in which there is no possibility of direct connection to the multiplex channel data transmission.

The controller 1 and the interface units 3 are interconnected by a local multiplex data transmission channel 5 (LMKPD), which is organized according to GOST R 52070-2003. In addition, the controller 1 and blocks 3 are connected by separate communication lines 6 with the power system of the aircraft and with the controls located in the aircraft cabin, designed to organize the functioning of the system (turn on, turn off, provide locks in terms of the safety of the use of TSA and the work of maintenance personnel, ensuring work in emergency situations) and representing a set of switching elements.

The multiplex data transmission channel in the ASP 7 (MKPD ASP) is designed to exchange with the ASP all the information necessary for the use of high-precision ASP controlled by the multiplex channel (application sequence diagram, initial settings of the TSA, target designation, TSA status).

The number of interface units 3, as well as their location is determined by the specific configuration of the placement of the TSA on the aircraft.

The system operates as follows.

When the aircraft power system is turned on and power is supplied to the weapon control system, controller 1 and interface units 3 are turned on with launching in the controller 1 and in blocks 3 of the starting integrated self-control programs. Start control programs are designed to determine the health of both the components of the system itself, and the health of the local and intersystem MCPD. After the completion of the self-monitoring, in the interface units 3, information on the results of the control is generated and an identification program of the type of suspended HSA is launched. The result of the monitoring and identification of suspended ASPs (presence, type) can be read by controller 1 on channel 5 or by the BWC on channel 2 (in case of failure of controller 1 or local data transfer channel 5). Controller 1 (when it’s in good condition) after completing self-monitoring, having received information on channel 5 about the results of monitoring and identification of suspended HSAs, forms a sign of the integrated health of the TSA control system and prepares information about the state of the system and the types of TSAs suspended at the corresponding suspension points for transmission to BWC on channel 2.

Then the pilot, using a special remote control that is part of one of the sensors of the on-board equipment, makes a choice for the use of specific types of TSA and sets the mode of their preparation and application, and then to controller 1 through channel 2, depending on the type (s) of the selected TSA from sensors receives information about the modes of preparation and application of TSA, information target designations. The controller 1 on channel 5 provides information in blocks 3 in the form of a serial digital code. This information contains information on what interface unit 3 must perform to prepare the TSA for use. If the controller 1 or the local channel 5 fails, the information necessary for the application of the TSA is transmitted directly from the BWC via the intersystem MKPD 2 to the interface units 3 and further to the TSA via the corresponding channels 4 and 7.

The interface unit 3, in accordance with the information received, provides the supply voltage and electrical signals necessary for the TSA to the selected TSA for use, as well as, in the case of TSA, in which there is no possibility of direct connection to the MCPD, targeting signals. If an ASD controlled by MKPD is being prepared for use, target designation signals to the TSA are received via the multiplex data transmission channel to the TSA 7. By targeting signals, the TSA is aimed at the selected target. After pointing the TSA to the target, the pilot presses the “Start” combat button located in the cockpit of the aircraft, the signal from which arrives via communication lines 6 to controller 1. Controller 1 on channel 5 or the BWC of the object on channel 2 (if controller 1 or LMKPD 5 fails) issues to the block 3 a command to use the TSA, after receiving which block 3 issues start-up commands to the TSA via channel 4. The use of the TSA occurs, and the effect of interference caused by the "hot" disconnection of the TSA from the corresponding interface unit 3 does not affect the remaining TSA. In addition, the failure of one of the blocks of the interface 3 does not lead to the impossibility of using the ASP by the remaining blocks of the interface 3.

In the event of a failure of either channel 2 or BWC (target designation sensors), the controller 1 contains a program that allows the pilot to manually use the TSA without transmitting target designation information, controlling the operation of controller 1 via communication lines 6.

Thus, the introduction of multiplex data transmission channels in the TSA and additional multiplex data transmission channels in each of the interface blocks for connecting them to the intersystem MCPD and multiplex data transmission channels in the TSA made it possible to reserve control channels for the use of the TSA and provide independent control of the TSA according to the MKPD for each point ASP suspension, to increase the fault tolerance of the functioning of the system and, consequently, the effectiveness of combat use of aircraft.

In addition, the proposed system is universal and easily adapts to any aircraft, since this requires, basically, only software refinement of the system and a change in the number of interface units.
