Description

   The invention relates to automation and computing, can be used in automated monitoring and control systems, in data acquisition and processing systems. A device is known that provides registration of information in the order of its arrival at the device input, which contains an input unit, a discrete information conversion unit, a time counter, a pulse counter, a control unit, an encryption unit, and a print control unit Sch The disadvantage of this device is the limitation of its part of the allocation and registration of code information: the device does not register operational information. A device is also known which contains a data input unit, single pulse formers, a pulse counter, a print control unit and a delay element connected in such a way that operational code information embedded in a specific, predetermined string pj frame is selected. The disadvantage of this device is the failure to register code commands of an arbitrary frame line. The device is capable of inserting and recording operational information embedded only in a predetermined line of a frame. However, for example, in monitoring, when a parameter goes beyond the limits of a permissible value, it becomes necessary to evaluate the instrument characteristics associated with this parameter. To do this, you must select the information contained in another line of the frame. The structure of the known device does not allow to select the necessary line of the frame and quickly select it from the information flow, i.e. insufficient selectivity. The purpose of the invention is to improve the accuracy of the device. This goal is achieved in that the device containing the data input unit, the outputs of which are connected to the first and second inputs of the printing mechanism and to the first single-impulse generator, the output of which through the delay element is connected to the first input of the counter of impulses, the second single-pulse generator, which connected to the second input of the pulse counter and the data input unit, the print control unit, the output of which is connected to the third input of the printing meanism, the first input of the print control unit The input to the output of the printing mechanism, and the second input to the output of the third single pulse importer, additionally contains a block for specifying the initial conditions, the elements AND, the element OR, the output of which is connected to the input of the third Former single pulse, each of the inputs of the element OR. connected to the output of the corresponding element I, the first inputs of each of which are connected to the corresponding outputs of the pulse counter, and the second inputs to the corresponding outputs of the initial conditions block, as well as the fact that the initial conditions block contains a keyboard, the fourth Single Pulses generator, shifting the registers and a decoder, the first keyboard output being connected to the input of the fourth single pulse generator, the output of which and other keyboard outputs are connected to shift registers The outputs of which are connected to the inputs of the initial conditions setting unit and with the corresponding inputs of the decoder, the outputs of which are connected to the outputs of the initial conditions setting unit.

The drawing shows a block diagram of the proposed device.

The scheme contains a data input unit 1, a printing mechanism 2, first 3 and second 4 single pulse shapers, delay element 5, pulse counter 6, print control unit 7, third single pulse shaper 8, initial conditions block 9, elements 10 AND, element 11 OR. The initial conditions setting unit 9 contains a keyboard 12, a fourth driver of 13 single pulses, shifting registers 14, having first, second and third bits 15-17, and a decoder 18. The inputs of data input unit 1 are connected to a sensor (not shown). The outputs of the shift registers 14 and the inputs of the decoder 18 of the initial conditions setting unit 9 are connected to the outputs of the task unit of the corresponding code (not shown).

The device works as follows.

From the sensor functioning according to a specific program, code commands enter the data input unit 1, which isolates the incoming commands and transmits them to the corresponding inputs of the printing mechanism 2. To make it easier. code commands could be deciphered, it was tried to be packaged in special ways. The most widely used method is when code commands are packed into frames consisting of lines, in this case code commands are accompanied by two service signals: a frame marker and a line marker. One of the lines in the frame is occupied by operational information. Suppose the operational information is in the sixth row. Then from block 9 the string is set. When manually setting a line on the keyboard 12 dial a number, successively pressing the key with the corresponding engravings, starting with a hundred of its digit number. At the same time, a signal appears at the corresponding information outputs of the keyboard 12, which is fed to the input of the first bit 15 of the corresponding register 14, which stores the keystroke on the keyboard 12. The number of registers is equal to the base of the number system. When the key is released, a signal is sent to the generator 13, a single pulse is given, and a single pulse appears at the output of the generator 13, which is fed to the shift registers 14. The state of the first bits 15 of the registers 14 is copied to the second bits 16 by a single pulse, and first set to zero. In this case, the state of the outputs of the second bits 16 of registers 14 corresponds to the code of the most significant bit of the dialed number. When you press the same or any other key of the keyboard 12 again, the digit code of this key is again stored in the first 15 racks of the shift registers 14, and when released, a single shift signal is received, as described above. The state of the second bits 16 is rewritten to the third 17, the first 15 to the second 16, and the first bits 15 are again set to zero. If the number of lines in the frame. more than two digits, the number of bits in the kgikd shift register 14 is increased by the corresponding number. From the second output of block 1, the signal also disappears, to the back front of which the driver of 3 single pulses reacts and sends a second pulse through the delay line 5 to the pulse counter 6, which will fix it and raise the signal to the first input of the pulse counter element 102. the outputs of each bit are used. The sensor continues to transmit information from the third to the fourth, etc. lines, accompanied by its signals from the second output of block 1, similar to the first and second lines. Shaper 3 single HMnyjibcoB, feeling the arrival and departure of the signal markers row, each time through the element 5 delay a single pulse at the input of the counter 6 pulses, which counts these pulses and sends a signal to the first inputs of the elements lOg, 10, etc., whose understanding in doing so. unchanged due to the absence of signals at the second inputs. Upon the arrival of the sixth pulse (it was previously agreed that the operational information is in the sixth row), the pulse counter b will give a signal to the Lion input of element 10e, And, to the second input of which there is a signal from block 9. Element 10, "And will work and increase The element 11 OR would be sent to the pioneer by means of 13 single pulses, which, according to this signal, would generate a short signal to the second input of the print control unit. If there is a readiness signal of the printing mechanism at the first input of the print control unit, the last one at this signal will generate a Signal Record on the control input of the printing mechanism 2, according to which the printing mechanism records the prepared information of the sixth line. If from block 9 an n-line is specified, then by the arrival of an n-th pulse from a formarivatel of 3 single pulses, the counter of 6 pulses will send a signal to the n-th output, which will trigger the nth element I, by which the printing mechanism 2 will record information of n oh row frame. The sensor continues to transmit code information when all the lines in the frame have finished, the signal from the first output of block 1 is cleared (or a negative polarity signal is sent), which means that information about the next frame has begun. At the first output of block 1, the signal will also disappear, the shaper of 4 single pulses will react to the falling edge of this signal and generate a single pulse to the second input of the pulse counter b, which will be reset by this signal and start counting the rows of the next calra with zero. The use of the proposed device in data acquisition and processing systems, in automated control and monitoring systems allows, in comparison with known devices, to capture and record operational (priority) code information depending on its importance in this particular situation. The structure of the device allows, depending on the importance in this particular situation, to select this or that information. claims 1.
