AI, I mA are used as in-motion devices. The device works as follows. At the initial moment, all the bits in the module are in the zeroed state, i.e. the indicator light emitters 24 do not emit light, and the counting trigger 15 is in the zero state due to the application of a positive pulse to its reset input 19. This module can operate in two modes: the mode of recording any information in the module,. mode of information transfer to the module. Consider the mode of recording any information in the module. To this end, the counting trigger 15 is set to one state by supplying one pulse to its counting input 18 and from its direct output 16 a high positive potential is removed, which is fed to the input of the second amplifier 20, amplifying this signal and feeding it to light emitters 124 i.e. all indication bits 1} .J are prepared for recording information. Empty must write information in bits CD, IM 2,2 3, i C, 2. 5, Z-THIS, an optical signal is supplied to the fourth additional photoreceivers 10 of these bits, which prepares these photodetectors 10 for recording information, i.e. the resistance of the fourth additional photodetectors 10 becomes small. Then a short pulse is applied to the input 22 of the information recording. The amplifier 21 amplifies it, and from the output of the amplifier 21 a signal is applied to the fourth additional photo-terminals 10, as a result of which these bits, 2.1 2.2 g, 2 s, 2 transits 12, 12.2, ZL 1 into excited state, as the transistor 6 goes into the Nascene mode due to the presence of a high positive potential at its base. A positive feedback, implemented on the second additional photodetector 8, supports the transistor 6 in the saturation mode. The indicator light emitter .23 will constantly emit light. Thus, the information will be presented in the following form (excited bits are indicated by the intersection of two segments inside a square): The transfer mode of the recorded information is divided into four sub-modes: transfer of information to the right; information transfer to the left, information transfer up and information transfer down. In order to transfer information, it is necessary that the switching contact 25 of the switch 13 be connected to the third closing contact 26. The counting trigger 15 is in a single state. Let it be necessary to shift the information recorded in the recording mode to the right by two indication bits. For this, four pulses are applied to the counting input 18 of the trigger 15. With the arrival of the first pulse, the trigger 15 goes to the zero state, i.e. a high positive potential from the inverted output 7 is fed to the input of the first amplifier 14, which amplifies this signal. Due to the fact that on the first photodetector 3 of the excited discharge Hfj where i 1, M, j 1, N the light from the first additional light emitter 23 was present, the resistance of the first photodetector 3 becomes small, and accordingly, with the arrival of the first pulse, a high positive potential through the photodetector 3 is fed to the base of the transistor 6 and this discharge remains in the excited state, i.e. the first photodetector 3 and the light emitter 2 are already becoming elements of supporting the transistor 6 in the saturation mode; i.e., in each excited state, preparations are made for bias information. When considering the principle of operation of the circuit, we assume that only the bits with the indices Ij, l ,, L g-fz y 2 D are in the excited state, information input is shown, Te-i and take the values 1,2, 2,1, 2.2, 3.2, 4.2, 5.2. With the arrival of the second pulse, the counting trigger, 15, goes to the single state, and the high positive state. the potential taken from direct output 16 is amplified by a second amplifier .20 and fed to the third locking contact 26, and due to the presence of an optical signal at the second photodetector 4 of the subsequent bit 1, the light emitter 2 of the previous bit ,,, bit Ijj goes into the excited state, since on the second photodetector there are 4 bits j. the resistance becomes low, and a high level of positive potential is applied to its electrical output, which will actually be present at the base of transistor 6. If this bit has been in an excited state before, so it will remain in it with it. Bit 1j is zeroed out if the preceding bit did not emit light, and remains in the same state, if, on the contrary, with the arrival of the third pulse, preparation is made for shifting information, and with the arrival of the fourth pulse, another shift is made. In the process of displacement, the next subsequent discharge in the displacement process carries the information of its previous discharge, and consequently, the information recorded in the information recording mode is shifted by two bits to the right and the excited become in the discharge discharge DS, 4.4 C, 4 4, 4 v To transfer information to the left The closing contact 25 of the switch 13 is connected to the fourth 3ahibic contact 27. Let it be necessary to shift the recorded information to the left by two indication bits. For this, four pulses are applied to the counting input 18 of the counting trigger 5. This mode differs from the right shift mode, described earlier, only in that the shift is performed not by the second photodetector 4, but by the third photodetector 5, bit 1; j optically coupled to the light emitter 2 bits 1 {j ,. As a result of the information shifted by two bits to the left, recorded in the recording mode, the bits 1, „, 1, 1, 3,„,, 1 ,, will be in the excited state. We obtain the picture presented in the following form: This picture it is also obtained by optical light sources of light emitters of 2 bits of the first column with third photodetectors of 5 bits of the last column. To transfer information upward, the switching contact 25 of the switch 13 is connected to the first closing contact 11, and the bias is carried out on the first additional photodetector 7, bit C, optically connected to the light emitter 2, 1, ..,;. As a result of the displacement, the bits will be in the excited state :. j 21 til I--. We get the following C 2 4 g 1 W, i t- t gap picture: in the information transfer mode, the switching contact 25 of the switch 13 is closed with the second closing contact 12, and the bias is carried out by the second additional photodetector 8 of Ij optically coupled light emitter 2 bit yes If-), Emit light will be bit, j ,, Ijj ,. h-2. Glitches as follows: All optical links between the bits of the outermost columns and the outermost rows are designed to ensure that the information recorded in the module is not lost during the offset. Assuming that in the excited state there was a discharge of the last column, then when shifting to the right by one bit the excited one becomes the one that is first in the same row. The proposed module has the advantage over the prototype, which consists in expanding its functional capabilities due to the ability to display any information in a two-dimensional coordinate system, as well as to move it in four directions (right, left, up, down) without losses. This is achieved by introducing one switch, three amplifiers, four additional photodetectors, an additional and indicator emitters into each discharge unit. The switch and photodetectors allow you to shift the recorded formation to any of the four sides. Amplifiers are introduced to supply any number of bits, since the outputs of the counting trigger have a limited current that is sufficient only to provide a limited number of bits, and the amplifier allows all bits included in the module. The first additional light emitters allow shift any information, and the second additional light emitters, the indicator light, allow you to display it. In addition, the device has the advantage of increasing its reliability of operation, due to the fact that the switching of each subsequent regenerative optocoupler does not depend on the duration of the pulses themselves, and therefore, the difficulties of pre-individual selection and selection of the pulse duration disappear. Thus, in the course of the operation of this device, the possibility of false triggering of regenerative optocouplers is eliminated due to 4Tof; Cr pp, .r.o, the response time of the regenerative optocouplers (the response time of the regenerative optocouplers can vary) as the switching process of the optocouplers is controlled by a counting trigger. The proposed multidimensional module for displaying information can be used in pulse measurement and information technology, in various automation devices, and if M 1, then as successive adders, reversible counters, shift registers, time interval converters to code, moreover, as digital scoreboard or screen.
