Description

one

The invention of OSG is in the field of devices that measure and record the parameters of electrical loads.

A device for recording power consumption recordings on a magnetic tape is known, which contains electrical energy meters with pulse sensors, a load graph recorder on a magnetic tape, a unit for reading and converting information, a digital printing machine or a perforator .1 J.

The disadvantage of this type of recorders is the presence of an intermediate information carrier (magnetic tape, tape J, which leads to a decrease in the reliability of the device and complication of its design; when the network is disconnected, information is lost due to distortion of the load distribution in time.

An automatic multichannel electrical load recorder is also known, consisting of analog current and voltage transducers, a channel switch, analog-to-digital conversion units of measured values, a counter unit, a synchronization unit, a service symbol block, and a perforator.

Signals from. Transmitters through the switch are alternately fed to blocks of analog-to-digital conversion of measured values, from where they in pulse form are fed to the input of a counter unit that converts a numerical code into a binary one. Further, the binary code signals are amplified and recorded by a perforator. The operation of the recorder is controlled by a synchronization unit. Simultaneously with the measured parameters, service symbols necessary for inputting into a computer are recorded on the perforator tape;
