(54) ИМПУЛЬСНОЕ ЛОГИЧЕСКОЕ УСТРОЙСТВО С ПАМЯТЬЮ(54) PULSE LOGICAL DEVICE WITH MEMORY

Изобретение Относитс к автоматике и коммутационной технике, а именно к логическим устройствам с пам тью, и может быть использовано в системах автоматического управлени , контрол и св зи.The invention relates to automation and switching technology, namely to logic devices with memory, and can be used in systems of automatic control, control and communication.

Известны магнитные логические элементы с пам тью 1.Known magnetic logic elements with memory 1.

Эти элементы обладают ограниченными логическими и коммутационными возможност ми, так как у них отсутствуют потенциальный выход и гальваническа разв зка цепей управлени и нагрузки.These elements have limited logical and switching capabilities, since they lack the potential output and the electrical isolation of control circuits and loads.

Наиболее близким техническим решением вл етс импульсное логическое устройство с пам тью, содержащее крестообразный сердечник из ферромагнитного материала средней маигнитной жесткости, на котором pacfioложены обмотки управлени , и герконы , замыкающие свободные концы сердечника . .Кажда пара обмоток при.подаче на них включающих импульсов коммутирует соответствующий геркон.The closest technical solution is a pulse logic device with a memory containing a cruciform core made of ferromagnetic material of medium magnetic stiffness, on which control windings are laid, and reed switches, which close the free ends of the core. .Each pair of windings for switching on them the switching pulses commutes the corresponding reed switch.

Недостатком известного устройств вл етс то, что оно не может реализовать логические функции более, чем двух переменных.A disadvantage of the known devices is that it cannot implement logical functions of more than two variables.

Цель изобретени - реализаци логических функций более двух переменных .The purpose of the invention is the implementation of logical functions of more than two variables.

Ука-занна цель достигаетс тем, что в известном импульсис ч логическом устройстве с пг1м тью/ содержащем Ферромагнитный сердечник из ма0 териала средней магнитной жесткости, обмотки управлени и геркон, сердечник выполнен многоотверстньм из пр моугольных стержней равного сечени с незамкнутым отверстием на 5 одном из концов, обмотки управлени расположены на нечетных поперечных, стержн х, число которых равно 2п-1, где п - число переменных, а междУ выступами незамкнутого отверсти серпечника установлен по крайней мере один геркон.This goal is achieved by the fact that in a known impulse logical device with PGI / TU containing a ferromagnetic core of medium magnetic hardness material, control winding and reed switch, the core is made of multi-holes of equal section with an open hole at 5 one end The control windings are located on odd transverse rods, the number of which is 2n-1, where n is the number of variables, and at least one reed switch is installed between the protrusions of the open loop of the sickle rail.

Claims

The drawing shows a schematic representation of an example of a constructive device for realizing the logical functions of three variables. The device comprises a five-hole core of ferromagnetic material of medium magnetic rigidity, for example, barium ferrite with a coercive force A / m, rectangular holes 2 formed by rectangular rods of the same cross section, the size of which is determined by the magnitude of the working flow of the used magnetically controlled contact. The last hole of the core is knuckled at once, after Corollary end which has projections 3, between which is installed flax reed 4 so that its contacts close the magnetic circuit around the last openings of the core. The number of transverse rods 5-9 is 2p-1, i.e. in this example, 2-3 - I 5. On the odd transverse rods x 5,7,9. control windings 10–12 are located to which signals of input variables X are fed. The windings of input variables form the input logic of device X. The output logic of the device is realized by the contacts of the reed switch 4, and the internal logic is magnetized: e core 1, the operation of the logic device is realized in the following way. In the initial state, the core 1 is demagnetized, the input signals X are absent, and the contacts of the reed switch 4 are in the open state. The control input signals are a logic unit pulse signal, which definitely provides for the lagging of core 1, and the logic zero signal - the absence of a pulse. When a signal of a logical unit (voltage U) is applied to the input of the first winding 10, the magnetic flux is closed through the rods 5 and b, filling them, Hercrn 4 does not work, because the magnetic flux does not pass through it. Upon receipt, the trace of the signal of the logical unit, for example, at the input of the third winding 12 X, I (U,), respectively, the rod and part of rod 8 is saturated. The magnetic flux formed by the third winding 12 splits: part of the flow flows through rod 8, the other through. 4, The ratio of the parts of the flow is equal to the ratio of the conductivities of the corresponding sections. The stream flowing through the reed switch 4 is insufficient for its operation. When rta receives the second winding 11 of the next signal of a logical unit (U2), its magnetic flux imposes rod 7 and the unsaturated part of the rod 8 and, through the reed switch 4, triggers it. output X, appears. With other arrival sequences of signals X; the rod on which the winding and partially adjacent rods are located will be fully magnetized. Only the presence of all input signals, and therefore magnetic saturation in all rods, triggers the reed switch 4, (Releasing the reed switch 4 occurs when the device is zeroed, which is carried out by applying demagnetizing and pulses to all control windings 10-12, When used on the output of the device of the described design of the switching reed switch 4 can be implemented functions ZI and ZI-NOT. As an actuating element in the device, instead of the reed switch, other magnetically controlled elements can be used, For example, an electromagnet, an inductor of saturation, a magnetic diode,. The invention allows to expand the logical capabilities of the device, realizing the logic functions of many input variables. What is different is that, in order to implement logical functions of more than two variables, the core is made Multiholes of rectangular rods of equal section with by an open hole on one of the hoops, the control windings are located on odd transverse rods, the number of which is 2n-1, where n is the number of variables, and at least one reed switch is installed between the projections of the open-hole core.
