Description

The invention relates to airborne electronic equipment and is intended for the preparation of unguided aircraft weapons for use.

Modern aircraft guidance and weapon control systems make it possible to more effectively use unguided aviation weapons of destruction (NASP) by increasing their accuracy characteristics. This is achieved by using the individual (more detailed) characteristics of the NASP for more accurate adjustments to the on-board digital computer (BCM) of their discharge path. For example, such a characteristic may be the mass of NASP, which may vary due to manufacturing errors. The input of individual characteristics and other data identifying NASP for the corresponding suspension units in the aircraft computer is based on manual input using the data input panel. With this input method, it is possible to make input errors, for example, due to the carelessness of the “human factor”, since the data during the suspension is first recorded in “paper form”, and only then from the “paper form” are entered into the aircraft computer. This is due to the absence of any electronic control systems or other storage devices on the NASP that could interact and transmit data to the digital computer.

The weapon control system is known from the prior art (patent RU 2146835 C1, G06F 17/00, 03/20/2000), according to which the system consists of a command unit and remote units for each suspension point. The command unit contains a time interval unit, a one-time command unit, an integrated gun installation control unit, an unguided weapon control unit, a guided weapon control unit, a communication center with a digital computer and a communication unit with remote units. Each of the remote units contains a switching unit, a signal conversion unit, and a communication unit with a command unit. The invention allows to expand the functionality of the system, reduce the number of wired communication lines, reduce the weight of the system, and also increase the number of suspension points and types of weapons without significant modifications to the equipment. This system connects the aircraft’s onboard complex only with the suspension units of unguided aircraft weapons, which does not allow the automation of the input of their individual characteristics into the computer and to monitor the compliance of the entered data with the NASP.

The objective of this invention is the creation of a weapon control system that allows you to automate the input of unguided aircraft weapons into the aircraft computer to eliminate manual input errors, reduce their preparation time and allow the use of an extended number of individual characteristics in guidance algorithms without the need for manual input.

The technical result of the invention is to increase the efficiency of the use of unguided aircraft weapons by reducing the time of their preparation and eliminating errors in entering data of individual characteristics of unguided aircraft weapons into an onboard digital computer.

The expected technical result is achieved by the fact that the node of the suspension of aviation weapons contains a radio frequency antenna, and uncontrolled aircraft weapons contains a passive radio frequency tag with memory, while the tag memory contains individual characteristics and the identifier of this uncontrolled weapon, each radio frequency antenna of the suspension unit is connected by a transmission channel data unit data reading, which is connected by a data channel through a communication node with the on-board digital in a numeral machine, while the input of the individual characteristics and identifier of an uncontrolled aircraft weapon relative to the attached suspension unit in the on-board digital computer is carried out automatically at the moment the passive RF mark falls into the range of the radio frequency antenna of the aircraft suspension unit, by reading the radio frequency antenna and transmissions to the on-board digital computer through a data reader and communication center, yes data stored in the memory of a passive RF tag.

The proposed invention assumes the use of gaining ever-widespread popularity of radio frequency identification technology (as a means of storage and transmission of individual characteristics and identifier NASP in the computer). RFID technology includes: a passive or active RFID tag with memory, a data reader and an RF antenna (receiver). In this situation, the use of a passive radio-frequency tag is more suitable, I do not need an additional power source, which is not available in NASP. In memory of a passive radio-frequency tag, all the information necessary for use during guidance or construction of the NASP flight path is pre-recorded, which, when read, is transmitted to the aircraft computer for further processing. Preliminary recording can be carried out automatically through electronic measuring instruments, or manually entered at the production or storage sites, eliminating input errors during combat training, when there are time limits leading to these errors.

The data reading unit is configured to periodically supply an activating signal to the antennas, which allows the tag to be read in automatic mode when it enters the antenna's field of action.

In a preferred embodiment of the invention, the use of a weapon control system in preparation for the use of unguided aircraft weapons is considered in the form of three components:

- fixing the radio-frequency tags with memory on the NASP during production or storage;

- equipping the aircraft with radio frequency identification antennas and a data reading unit (performed once);

- preparation for the use of NASP. The invention is as follows.

At the production or storage stage, parts of the NASP closest to the place for which the aircraft is suspended are attached with a passive radio-frequency tag. After that, the data containing all the necessary characteristics and identifiers that the digital computer uses to guide and build the NASP dump path is written to the memory of this label. For example, a mass of NASP can be written to an RF tag directly from an electronic balance.

Each NASP suspension assembly of the aircraft is equipped with a radio-frequency antenna, the aircraft is equipped with a data reader and connected to the radio-frequency antennas and to the communication center with the digital computer, data channels which is preferably located on the suspension assembly of the aircraft, to enable data transmission to the computer. Such data transmission channels are usually used to notify the crew of an aircraft that an NASP is reset. If such a channel is not suitable, then a new communication line (data transmission channel) with the digital computer is directly laid from the data reader. Radio-frequency antennas are connected to data reading units with the calculation of the possibility of identifying both NASP and the suspension unit on which NASP is suspended.

At the stage of preparation for use, after the NASP suspension, the radio-frequency tag falls onto the aircraft's suspension assembly in the field of action of the radio-frequency antenna. The antenna reads the information in the label (individual characteristics and identifier of the NASP) and transmits it through the data transmission channels through the data reader and the communication center in the digital computer. Either after the suspension of all NASPs, a specialist or a crew member sends a data reading signal to the digital computer via the data input console, which, in turn, is transmitted through the communication node to the data reader, which in turn activates the radio frequency antenna, and data is read and transmitted from memory RF tags located on the NASP in the aircraft computer.

Using this weapon control system reduces the time it takes to enter data on unguided aircraft weapons into the aircraft’s on-board digital computer, eliminate specialist input errors (human factor), automatic data reading and transmission minimizes the manual input process, and also allows you to expand the number characteristics used for guidance and construction of the NASP discharge path, as a result of the exclusion of a large amount of data input in B Digital computer in preparation. In addition, the implementation of this system does not require the purchase of expensive auxiliary equipment.
