Description

I

The invention relates to the field of instrumentation, namely to a device for recording information carried out by the method of magnetic recording of information on magnetic media.

A device for recording information made with a number of logic and switching elements, as well as with a switch, converters and the recorder 1 itself is known.

This device is rather complicated in design and does not allow information to be recorded at an increased frequency, which is associated with a limitation of the speed of the switch when it interacts with the converter and with the speed of movement of the magnetic carrier.

The closest technical solution to this invention is an information recording device comprising a recording unit connected to the inputs of a magnetic recorder and a synchronizer whose outputs are connected to an analog signal switch, a discrete signal switch, an analog-code converter and a time stamp 2 .

This device works quite reliably, but at the same time it does not allow simultaneous registration of slowly and rapidly changing parameters.

The purpose of the invention is the realization of the possibility of simultaneous registration of slowly and rapidly changing parameters.

To do this, serially connected parallel code converter and recording channel switch are included in the device, connected between the analog-code converter outputs and the recording block inputs, the service information generator connected between the time marker and the second inputs of the recording channel switch, and the analog-frequency converter, connected to the third inputs of the recording channel switch, while the output of the timer is associated with the second inputs of the switch discrete signals, and the second timer input is connected to a separate output of the synchronizer.

The drawing shows a block diagram of the described device.

The synchronizer 1 is connected simultaneously with the switch 2 analog signals, with the switch 3 discrete signals, with the converter 4 analog-code and with the marker 5 timers. Converter 6 analog-frequency, (|) op. 7 service information signals and parallel code converter 8 through different inputs of the recording channel switch 9 and recording unit 10 are connected to a magnetic recorder 11. Switch 9 has first inputs 12-15, respectively, second inputs 16 and 17 and third entrances 18-21. During device operation, signals of slowly varying parameters (for example, from sensors not shown in the drawing) are input to inputs 22–25 of switch 2, and output from synchronizer 1 is output to output 26. Similarly, signals go to inputs 27–31 of switch 3. As a result, a multi-bit parallel code and information about discrete signals and time signals are generated at the output of converter 4 (the drawing shows a special case for a seven-bit code and for one channel for discrete signals and time signals) A parallel code transducer is obtained. As a result, at the output of this converter a series-parallel code is formed, for example, a four-bit code and a potential impulse code. These signals are fed to switch 9 and then through block 10 of the recording to magnetic recorder 11. Signals of rapidly changing parameters are fed to inputs 32-35 of analog-to-frequency converter 6. In this converter, the 1e analog signal is converted into a frequency-modulated (FM) signal, which is fed to the inputs 18-21 of switch 9. In npoiiecce of work at the output of the synchronizer, the synchronization signals of switches 2 and 3, converter 4, converter 8 and switch 9 , while the synchronization signals received by the lit switch 9 are recorded in the required mode of code information signals. At the same time, the signal from the synchronizer generates a digital time using the timer 5, which is then also in the form of electrical signals fed to the overhead generator 7. With the help of a time stamper, accurate analog information is also linked to a specific command. The duration of the bit pulse of the time information corresponds to the polling period of all the channels of the switch 3, which allows the delivery of time information to any of its inputs. The proposed device is universal, which makes it possible to exclude from operation two separate devices for recording slow processes and for recording fast processes, which in turn reduces the power consumption of the equipment as a whole and improves the reliability of the recorded information. An apparatus for recording information, comprising a recording unit connected to the inputs of a magnetic recorder, and a synchronizer, whose outputs are connected to an analog signal co-switch, a discrete signal switch, an analog-code converter, and a time tag that differs from By the fact that, in order to realize the possibility of simultaneous registration of slow and fast changing parameters, serially connected parallel code converter and recording channel switch are introduced into it, between the outputs of the analogue code converter and the inputs of the recording unit, the overhead signal generator connected between the timer and the second inputs of the recording channel switch, and the analog-frequency converter connected to the third inputs of the recording channel switch, while the output of the time timer is associated with the second ones the switch inputs of discrete signals, and the second timer input is connected to a separate synchronizer output.
