Abstract

The invention relates to a magnetic recording technique, more specifically to multi-channel information recorders, a magnetic carrier. The aim of the invention is to expand the functionality of the recording devices, and by providing a change in the number of registered channels. The goal is achieved by introducing into the device three schemes OR. one-shot, control keys, and an I-block circuit. The device communication system allows you to select channels that correspond to the parameters to be registered, determine whether they need to be registered, and if not necessary, skip it. The remaining parameters are recorded in the usual order.

Description

The invention relates to a magnetic recording technique, and more specifically to multi-channel recorders of information on magnetic media.

A device for processing and accumulating information is known, which contains sensors connected via amplifiers and an analog-digital converter. To informational inputs of a storage device that includes playback, recording, erasing, and mode control units,

Closest to the present invention is a device comprising a group of information sources, keys, adder, analog-to-digital converter, register, recorder, magnetic head, pulse generator, counters and decoder, as well as a communication system that allows you to record data from several analog channels divided by time. For a number of applications, for example, when conducting hydrophysical studies, the recording device is required to perform

specific functions. In particular, the urgent task is to exclude some of the recorded parameters while maintaining the registration of all remaining ones. Such situations arise when the measuring channels get out of line (it is not advisable to record inaccurate information), but a more frequent case is to conduct a controlled experiment process. The specialist hydrophysicist in this case is interested in excluding the extra, in his opinion, in this experiment (zones) channels from the registration process, in order to provide a more detailed view of the profiles of hydrophysical parameters that are to be registered. This increases the information content of the experiment, making it more flexible.

The aim of the invention is to expand the operational capabilities by selecting the parameters to be registered.

The drawing shows a block diagram of the proposed device.

The output of control keys 14 is connected to the second inputs of the And 12 circuit block, the output of the And 12 circuit block is connected to the address inputs of the switch 1 and with: the inputs of the third circuit OR 15, the outputs of the second 13 and the third 15 OR circuits are connected respectively to the start and blocking inputs of the one-shot 9.

The device operates as follows.

Before starting the experiment, the operator and hydrophysicist, focusing on the required plan of the experiment, by means of control keys, block the faulty channels and those channels that are not subject to registration in this experiment. In the course of the experiment, the analog signals pass through switch 1, ADC 2 is converted and recorded to register 3 by the ADC ready signal. The pulses of the generator 6 shift the information into the recording unit 4, where it is encoded, and then to the magnetic head 5, which registers it on magnetic carrier. Counter 7 counts bits. and highlights informational words. The output pulse of the counter 7 through the first circuit OR 8 passes to the counter of channels 10, the decoder 11 at the same time converts the unitary code of the counter 10 to positional.

If the signal is blocked by the control key 14, then the signal at the output of the And 12 circuits does not pass, the desired channel of the switch 1 is not activated. At the output of the second circuit, OR 13, the signal appears, at the output of the third circuit, OR 15 does not appear (since it does not pass to the output of AND 12 circuits). The one-shot 9 is started and the pulse through the first circuit OR 8 is fed to the counter of channels 10, translation

his next state. If this signal is subject to registration, then it passes to the output of AND 12 and switches on the channel of the switch. At the same time, the OR 15 circuit turns on, the output signal is blocked by the one-shot 9. The conversion of the selected channel is carried out. The cycle repeats with each subsequent channel, with the extra parameters slipping, and the rest are recorded in the usual order. For eliminating pauses in registration, the period of the one-shot is chosen less than the value obtained by dividing the period of the pulses of the generator 6 by the maximum possible number; registration channels. Thus, it is possible to register from one channel to the maximum possible number of them in any combination. For this purpose, a laboratory model of a hydrophysical experiment data recording system is used, containing a switch K543KN2, a.c.p. КР572ПВ1, registers K564IR9, OFM recording unit and magnetic head ЗД24.232, tape recorder mechanism of Topaz, counters K564IE11, decoder on K564 microcircuits.

The use of the proposed device allows the registration of any number of analog channels in any combination, while increasing the quantization frequency of the remaining channels. .
