Description

MULTI-CHANNEL DEVICE FOR THE 1ST CONTROL OF TECHNOLOGICAL PARAMETERS OF THE UNIT.

The technical solution proposed as a utility model relates to the field of production of machines and assemblies for processing synthetic fibers and threads, and more specifically, to multiple-channel devices for controlling technological parameters, for example, temperature, pressure, flow rate, various executive elec- utes of a unit for processing synthetic fibers.

Known multichannel devices (Kosharsky B.D. and others. Automatic devices, regulators and; shravlyagtsiya machines., Engineering, L, 1968, pp. 730-770) for monitoring various technological parameters, made on the basis of electronic devices of the first and second generations.

The disadvantage of these devices is the high inertia, insufficient measurement accuracy, low reliability.

The closest analogue to the claimed utility model is a multichannel device for monitoring technological parameters (see prospectus GY Zakarpatpribor, 1990 for a Multichannel digital measuring converter Ш711 / 1й), containing a multichannel measuring converter, the inputs of which are connected to the sensors of the measured parameters according to the number of control channels, and each control channel has two positional exits for technological tolerance, alphanumeric printing; its device (ADCU), connected by power to many channel transmitter via a key element and a channel for transmitting information on the monitored parameters connecting data output from the multi-channel transmitter data input alphanumeric printer.

During operation, the device provides constant monitoring of the output parameters of the converter; it is printed out with an ADC.

Its output parameters. Frequent turning on and off the ADCU lead to a decrease in its reliability, wear of the AC11U parts, the consumption of paper and paste, etc.

The technical task of the claimed utility model is to increase the reliability of its operation.

The problem is solved due to the fact that a multi-channel device for monitoring the technological parameters of the unit, containing a multi-channel converter, the inputs of which are connected to the sensors of the measured parameters by the number of control channels, and each control channel has two position outputs for the technological tolerance. with a multi-channel measuring transducer by means of a key element and a channel for transmitting information about the monitored parameters, connecting the information output gokanalnogo transducer An information input from alphanumeric printer is provided with a logic unit, and a key element is made; / is editable, while the position outputs of the multichannel measuring transducer are connected to the inputs of the logic cell, and the output of the logic cell is connected to the control input of the key element.

The device proposed as a utility model differs from the known one selected for the prototype in that it additionally contains a logic cell, and the key element is controllable, while the position outputs of the multichannel measuring transducer are connected to the inputs of the logic cell, and the output of the logic cell is connected to the control input of the key element , which increases the reliability of the work due to the more rational use of the ADCP, as long as it is included in the work only if any of the parameters go beyond the technical biological tolerance ..

Thus, the proposed technical solution meets the criterion of a novelty utility model.

Models for industrial use

The drawing shows cxewa of the proposed device.

The device contains a multichannel measuring transducer I, the inputs of which 2, according to the number of control channels, are connected to the sensors 3 of the measured parameters, and each control channel has two position outputs for technological tolerance and a lot of 5. The device also contains an alphanumeric printing device (ADC) b, connected by power to a multichannel measuring transducer I by means of a key element 7. The device has a channel 8 for transmitting information about the monitored parameters, connecting the information the output of the multi-channel measuring transducer with the ALiJiy information input. The device is equipped with a logic cell 9, and the key element 7 is made controllable, while the positional outputs of the measuring transducer are connected to the inputs of the logic cell 9, and the output of the logic cell is connected to the L7PGEV with the input-10 of the key element 7.

13, the well-known Ш711 / 1И converter can be used as a multichannel measuring transducer I, the well-known printing output device Electronics MSb313 as an ADCU, and 9 or as a logic cell.

The operation of the device is as follows. Previously, for each of the channels of the multichannel measuring transducer, the corresponding task of the technological parameter is set, as well as its tolerance for the pulses is small and many, and then the device is put into operation. If the technological parameters for each of the available channels of the multichannel measuring transducer do not go beyond the technological tolerance, then output cell logic ots; the signal is on, the key element 7 is open and A1D1U6 is turned off and does not work. When going beyond the tolerance, few or many technological parameters of one or several channels of a multichannel measuring transducer signal about this come to the corresponding inputs of a small and a lot of logic cells 9, while the signal from the logic cells 9 post / drop

on the ; / controlled input 10 of the key element 7. Key element 7 closure -. It turns on and starts, which starts printing the output parameters of the multichannel measuring transducer. The printout is performed until the technological parameters across all channels of the multichannel measuring transducer are again included in the technological tolerance, after which the process is repeated again.

The technical advantage of the claimed device in comparison with the prototype is to increase the reliability due to the more rational use of AiJjiy, since the ADC is included in the work only if any of the parameters exceeds the technological tolerance. Due to this, wear of parts is reduced, that is, the durability and safety of the device are increased.
