SU524216A1 - Device for receiving telemechanical information - Google Patents

Description

The invention relates to the field of telemechanics and can be used in the system of collecting and transmitting information.

Receivers are known that contain distributors, counters, matrix circuits, linear nodes, and elements. And. Flj.

The disadvantage of these devices is the complexity of the circuit implementation, if necessary, of displaying telemetry signals in digital form.

The closest to the technical essence of the present invention is a device for receiving telemechanical information containing a distributor, outputs (which are connected to the corresponding inputs of the control unit, the first and second inputs of which are connected to the register input, the register outputs are connected to the information inputs of the intermediate yam tschko to the control input of which the third output of the control unit is connected, the output of the linear unit is connected to the control input of the register, the display elements are made s on a scaling element, yield 25 koto-

pogo is connected to the display unit, and a 2J generator.

However, such devices are complex, and the accuracy of reception is insufficient.

The aim of the invention is to improve the reception accuracy and simplify the device.

For this purpose, a pulse counter, a comparison unit, and the AND elements are introduced into the proposed device. Each output of the distributor is connected to the first inputs of the first and second elements AND the display element of the same name. The third output of the control unit is connected to the second input of the first element AND the display elements and to the control input of the pulse counter. The information outputs of the intermediate memory unit and the pulse counter are connected to the corresponding inputs of the comparison unit, the output of which, the fourth output of the control unit and the output of the generator | is connected to the inputs of the element I. The output of the element I is connected to the information input; the input of the counter of the pulses and the second input of the second elements And elements (mappings. In each element from & razheni outputs of the elements And are connected to the corresponding inputs of the counting element. In the drawing. There is a copy-circuit diagram of the poftcTj a. It contains the distribution liter 1, control unit 2, register 3, linear block 4 of intermediate memory 5, block one) compare 6, pulse counter 7 element 8, generator 9, and fusion element 10) consisting of elements 11 11, recalculated AEs 12, .ele iSHTOB AND 13 and idication blocks 14. The device works as follows With Distributor 1 and etch unit 2, emulses of transmission, reset, read and shift for each channel of received information are formed at the outputs of control unit 2 I Before reading information from regis) a shift 3 arriving at its input via a linear block 4 from a communication channel, from the output of control unit 2 simultaneously an intermediate memory block 5, an amp count 7 and a display element AND 11 of the display elements connected to a fy element, a reset pulse arrives, setting bits of the listed signals to the state corresponding to the code of 1 O. At this time, the AND 8 element is closed, so as to one of its inputs, the inhibiting signal, is sent to the corresponding output of the control unit. 1, after reading information from shift register 3 to intermediate memory 5, when a read pulse L is fed into the register соответствующего from the corresponding output of the control unit, the state of the SRI of bits in the intermediate memory does not match (by the time of reading 7) in the state IHHH corresponding to the code of the number O. At the same time, at the output of the comparator unit 6, a permitting signal appears, which enters the element 8 and the pulses; simultaneously from the generator 9 (counter 7 and through element 11 in) The element 12 corresponds to the element i. A When each time 1pc of the counter and the intermediate memory block 5 coincide, the output of the comparison unit 6 forms a signal that prohibits the passage of pulses from the generator 9 through the goiement E and B. Thus, in the scaling element 12, for example, a decade count, sets the number of pulses corresponding to one of the received information in a binary number system, which is displayed in digital form in the display unit. This embodiment of the device provides increased accuracy and simplifies the design in the case of the presentation of telemetry signals in digital form.
