BARREL FIREARM SYSTEM WITH CONTACTLESS DATA TRANSMISSION Russian patent published in 2020 - IPC F42C17/04 F42C13/08 F41A21/00 F42B15/01 

FIELD: weapons.

SUBSTANCE: invention relates to weapons, namely to devices for transmitting data to actuators of projectiles fired from firearms. Method is implemented as follows. Prior to firing projectile 12 is placed in barrel bore. Barrel is closed with a shut-off device. Electromagnets are switched on. Shell 12 passing along the barrel captures magnetic field of reference magnet 14, which is always switched on irrespective of information to be transmitted. Actually, it is counting magnet 14, according to which it is determined that at moment shell 12 flies over place of information transfer. Position of each next electromagnet is counted from it and it is determined whether it is on or not. When any combination of electromagnets is switched on, it is possible to determine what electromagnet is included under the condition that counting magnet 14 is always switched on during flight of projectile 12, and angular displacement of electromagnets is known. Only information electromagnets are used to transmit information. When flying past electromagnets in magnetic sensors, an electric signal is induced. Distribution of induced signals amplitude at inclusion of each of 16 combinations (4 bits) is unique. Therefore, by the type of distribution of voltage amplitude induced on all twenty coils, it is possible to determine the sequence of connected and disconnected electromagnets and determine the transmitted information. Magnetic field induced on each magnetic sensor is converted into an electric field which is transmitted to an analogue-to-digital converter by means of a resistor. Analogue-to-digital converter performs digitization of the obtained information and transmission to the information processing unit, which in its turn analyzes the obtained information and directs it to the memory unit. After receiving information from all magnetic sensors, the information processing unit performs combined analysis of the received and stored information and transmits to the memory unit the received volume of information containing, for example, coordinates of the destination, or distance to the target, or time to detonation of the detonating fuse.

EFFECT: technical result of the proposed invention is to improve the reliability of the device.
