(54) DEVICE FOR REGISTRATION OF INFORMATION

. The invention relates to automation and computing, can be used in automated monitoring and control systems, in data acquisition and processing systems. A device for recording information is known. the order of its arrival at the device input contains a data input unit, a discrete information conversion unit, a time counter, a pulse counter, a control unit, an encoder, and a print resolution block pQ. A disadvantage of this device is its limitedness in terms of the extraction and registration of code information: the device does not register operational information. It is also known a device that contains a data input unit, single pulse generators, a holdout element, a pulse counter and a print control unit, connected in such a way, which ensures the selection of operational code information embedded in a specific, predetermined stolen frame line 2, Disadvantage This device is documented with operational information of irrelevant information, which makes it difficult to evaluate operational information. A program of sources of code information is constructed, as a rule, cyclically. In a loop, one RLS is polled and code information is issued, regardless of whether the information has changed or not. If you do not screen out information whose value has not changed, the printing device will record the information of each cycle, which makes it difficult to analyze operational information. The purpose of the invention is to increase the speed of the device. This goal is achieved in that the device containing the data input unit, the outputs of which are connected to the corresponding inputs of the printing mechanism, the first and second single pulse drivers, the first driver, is connected to the first input of the pulse counter — the output of the second driver — to the WTO To the input of the pulse counter, the output of which is connected to the input of the third driver, the print control unit, the output of which is connected to the third input of the printing mechanism, and the first input d print control unit is connected to the enable output. the second delay element, the elements AND, the register and the code comparison unit, whose output is connected to the second input of the print resolution block, the first output of the third single pulse generator, is connected to the first input of the code comparison block, the second output of the third single pulse generator is connected to the input of the second delay element, the output of which is connected to the first inputs of the elements And, the outputs of which are connected to the corresponding inputs of the register, the outputs of which are connected to the corresponding chi Cf. second inputs Neny code block, whose third inputs and the second inputs of AND gates connected to respective outputs information data input unit. The drawing shows a block diagram of the proposed device. The device contains an input unit 1 for data input, a printing mechanism 2, the first and second formers 3 and 4 of a single pulse, the first element 5. delays, a pulse counter 6, a third one, a single impulse driver 7, a print control block 8, a second delay element 9, 10 register elements 11, and a code comparison block 12. The device works as follows. The code information is received from a function of a source of information according to a specific program to data input unit 1, which decouples the power of incoming commands to the corresponding inputs of the printing mechanism 2. To make it easier to decipher the code information, it is tried to be packaged using special methods. The most widely used method is when code information is packed into frames consisting of lines, in this case the code information is accompanied by two service signals: the block 1 frame signal coming from the first input and the line signal received from the second block input One of the lines in the frame is occupied by operational information. Let us assume that the operational information is in the sixth line (this condition is stipulated in advance when developing the device). Suppose that a functional source of information (not shown on anything else) began to produce information of the first frame. In block 1, the data on the VITS signal, which is sent to the shaper 4 single and myca, the latter will emit a short single pulse on this signal, according to which the counter of 6 pulses will be reset (it will not return to its original position). At the same time, at the second output of block 1, the water of the data on the Vits signal, which is sent to the driver 3 of the single pulse, the latter will issue a single pulse about this signal, which will go through the first delay element 5 to the input of the pulse counter b. Pulse counter 6 will record the first pulse, signifying the arrival of information in the first row. The source of information, after issuing the information of the first line, will remove the signal of the second output of block 1 (or a negative polarity signal), this means that the information of the second line has begun. In the second code of block 1, the signal will also disappear, the leading edge of which will react, and the driver of the 3 single pulses will generate a second pulse through the first EleHetHT 5 second pulse to the counter 6 pulses, which will fix it, m. will fix the arrival of the second line information. The source of information will continue to give information to the third, fourth, etc. lines, accompanied by its signals from the second ekhod of block 1, analogous to the first and second lines. The shaper 3 of a single pulse, reacting to the arrival and departure of the signals of the second output of block 1, each time through the first delay element 5, will generate a single pulse to the input of 1 1 6 pulses which counts these pulses. Upon the arrival of the sixth pulse (it was previously agreed that the operational information is in the sixth row), which means that the sixth row information has started, the pulse counter b will send the signal to the input of the single pulse generator 7 to the end of the frame. Shaper 7 on this signal is better, firstly,. a short signal to the first input of block 12 of the code comparison, which by this signal will produce a bit comparison of register 11 codes with the code of information bits of data input block 1. Since the register 11 is still in the initial state, i.e. zeros are written in all bits, then if in the data bits of data input unit 1 some information is contained (units in some bits). the value of the codes being compared does not match, and block 12 will give a signal to the second input of print resolution block 8, and if the value of the codes being compared coincides (in this case there is no information), block 12 does not compare the code to block 8. In the presence of a signal with unit 12 comparison of codes and readiness signal of the printing mechanism 2 print control unit 8 will generate a signal Record on the control input of the printing mechanism on

receiving and recording information. The printing mechanism 2 records the prepared information on this signal. The shaper 7 single pulses, secondly, will generate (via the second output) a short signal, which through the second delay element 9 enters the first inputs of elements 10 I. Elements 10 I, on the second inputs of which there were signals from the data input unit 1, are opened , and the register 11 will write the code of the information bits, the data input block 1, and the code comparison block 12 in the next comparison compares the information of the next frame with the previous one. If it does not differ from the previous one, then it will not give permission for its printing. The second delay element 9 provides the necessary time interval so that the comparator unit 12 will be able to start comparing the codes first, and then writing the current value of the information codes to the register 11. As mentioned above, the shaper 7 of the single pulses must pick up one short signal from the counter b of pulses to the code comparison block 12 and the second to the second delay element 9. An example of a driver 7 is the following scheme: two tanks connected by their high-resistance resistances are connected to the driver's input (the second cover of one of the containers is connected to the first output of the driver, and the second cover of the second capacitor, whose capacity is 10 times larger than the first, connect to the second output.

The source of information 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 by a negative polarity signal), which means the information of the next frame has begun. At the first output of block 1, the signal will also disappear. The front edge of this signal will react to the second single pulse shaper 4 and issue a single pulse to the zero line of the pulse counter b, which will reset the signal and zero from the next frame. The first delay element 5 ensures, firstly, that counter 6 has time to reset before the arrival of the first line signal, and second, that the code information has been prepared at the first input of the printing mechanism 2. Re. 11 can be performed, for example, on triggers ( for each data bit, one trigger), which uses a zero and a single output. The code comparison unit 12 produces a comparison of the first input code with the code of the second input. Comparison unit 12 can be executed by a set of schemes AND in the form of a pyramid.

on the elements And the first line of the pyramid connect the corresponding bits from the first and second input of the comparison unit 12, the logical element is NOT placed on the output of the ziramide, the output of which is connected to

5 to the first input of the additional element I, to the second input of which the signal from the first 0 output of the imaging device 7 is connected, and the output of the ET: RGO of the element I is the output of block 12 in comparison;

to

The proposed device completely eliminates repetitive information and registers only useful operational information.

Thus, the structure of the proposed invention allows to reduce the complexity of the analysis of operational code information, while increasing the efficiency of the analysis of operational information.
