Description

one

The invention relates to instrumentation n can be used in devices with point recording for registering parameters with a large range of speeds of their change, for example, processes that are statistically distributed over time.

A device that provides a point recording of the recorded parameters 1.

However, with a high rate of change of parameters, decoding the records is difficult. This is due to the fact that with point recording and abrupt changes in the measured value of paper shuffle, they are many times smaller than along the ordinate axis, which makes it difficult to recover the curve.

It is also known to register a device containing a tape mechanism, a generator of reference pulses connected to the control input of the memory register, a generator of clock pulses and a serially connected decoder, key and writing elements 2.

The disadvantage of this device is also the difficulty in deciphering the recording curves at high rates of change in the recorded value due to the lack of consistency of the resulting graph.

The purpose of the invention is to increase the consistency of the recording results.

The goal is achieved by introducing a reversing counter in the device, a code comparison circuit and two AND elements, with

10 inputs, comparison codes. connected to the outputs of the register and the counter, the outputs - with the first inputs of the elements And, the second inputs of which are connected to the output of the clock generator, the outputs of the terminals And

15 are connected to the forward and reverse counts of the reversible counter, and the counter outputs are connected to the inputs of the decoder.

The block diagram of the device is shown in the drawing.

The device consists of a memory register 1, a reversing tape mechanism (not shown), a counter 2, a code comparison circuit 3, a decoder 4, keys 5 writing 392 elements 6, elements 7 and 8, clock generator 9 and generator 10 reference pulses. The output of the memory register and the reversible counter are connected to the inputs of circuit 3 of the crawHCjntH codes. The outputs of counter 2, in addition, are connected to the inputs of the decoder 4. The delish 4 is connected with keys 5, which in turn are connected to writing elements 6. The outputs of the comparison circuit A B and A B are connected to the first inputs of the And elements 7 and 8. The second the inputs of which are connected to the generator output 9 clock pulses. The outputs of elements 7 and 8 are connected to the inputs of the direct and reverse counting of the reverse counter. The output W of the reference pulse generator is connected to the input of the memory register. The device works as follows. On command from the generator 10 of the reference pulses, the code of the number A corresponding to the measured property is recorded in the memory register 1. The recorded number A is compared with pattern 3 of comparison of codes with the code of number B (the result of the previous measurement) recorded in counter 2. If the number is AB, then the resolution is applied to AND 7, if AB, then to AND 8. In this case, clock pulses are passed to the corresponding input of counter 2 until the decoder 4 using keys 5 includes writing elements 6 corresponding to numbers from B to A. At the same time, all values corresponding to numbers from B to A are printed on the chart tape, i.e. Points B and A are connected by an unbroken curve. In counter 2, after the end of the comparison of numbers, the number corresponding to the value being measured is recorded. After the diagrams of the tape are moved by me and the next pulse of the generator 10 is received, a new number A is recorded in the memory register 1, which is compared with the result of the previous measurement B, and the work cycle is repeated. Depending on the rate of change of the recorded value and the requirements for their deciphering in a number of cases, it suffices to record (combine) the results of two previous measurements with a resolution of 2, 3, 4, etc., of the lowest-order unit of the recorded value. For this, the code comparison circuit can be executed with an accuracy of 2, 3, 4, etc., of the least significant units of the value being written. The proposed recorder is significantly different from the known ones. Thus, in the known recorders, in each measurement only the value corresponding to the measured value is printed. With large gradients, changes in the measured value, especially when recording non-periodic processes, for example processes that are statistically distributed in time, the distances between points are quite large. The curvature curves are practically not decipherable. The proposed registrar does not have this drawback, which allows it to be used to register non-periodic processes, including those that are statistically distributed in time.
