SYSTEMS FOR INPUTTING INFORMATION FROM P:VEUMATIC TRANSMITTERS INTO CONTROL

[Text] Inputtinb information from transducers of process parameters with a pneu-
matic unified output signal (called pneumatic transmirters from here on) into con-
trol computer systems is a problem in engineering implementation of sutomated pro-
cess control systems in the chemical, petrochemic:al a.nd related industries. As the
practice of development of such automated process control systems indicates, sig-
nals from pneumatic transmitters, as a rule, account for 50 percent of the overall
amount of information input automatically.
The most widespread method of inputting information from pneum3tic transmitters
' into cont:ol computer systems uses individual analog pneumoelectric conve~ters
that convert a unified pneumatic si2nal of 20 to 100 kPa (0.2 to 1 kgf/cm ) into a
unified electrical signal of 0 to 5 mA 'Lhat then goes to the load units (BN) in
the USO UVK [devices for object communication with a control computer].
- The widespread application of this information input method has caused a severe
shortage of pneumoelectric converters, which is increasing continuously because of
the increase in the number of automated process control systems that are being
developed. Information systems built on the principle of individual conversion of
- signals turn out to be very bulky and inconvenient in operation, and monitoring
Lhe working order of the i_nformation channels in them is difficult. Existing
engineering solutions for group checking of the con'verters by using pneumatic
= swicthing devices and reference elements for standard pressures are also not noted
for compactness [1]. More promising is the input of information from pneumatic
, transmitters that have group switching and converting devices within them.
Information from transmitters is usually input now by using PK-3 type pneumatic
switches, controlled by control computer systems, thaL switch pneumatic signals in
advance [2]� In doing so, there is one PK-3 switch and PE-55M converter for every
seven pollable pneumatic transmitters (one switch input is usually taken up by a
source of standard pressure and is used to check the working order of the con.verter).
Using this information input met!:od permits a substantial reduction in the number
of pneumoelectric converters and a solution to the problem of checking theni in each
polling cycle. Howeier, this method has a number of substantial shortcomings.

As industrial tests of these systems have shown, polling the pneumatic transmitters
takes no less than 16 seconds of machine time in each cycle. During this time,
the control computer cannot perform other tasks. The PE-55M pneumoelectric con-
verters often fail (adjustment is knocked off) because of the constant sudden
chatiges of pneumatic signals at the inputs. The information systems continue to
remain rather cumbersome.
The most promising method of inputting information into control computer systems
from pneumatic transmitters at the current ?evel of development of technology is
the speeded-up balancing method based on simultaneous comparison of the transmitter
sibnals with a developed balancing signal by using null-balance devices placed in
the individuai transmitter circuits. There are a number of ways to implement thJ s
metlzoci [3, 41. Nowever, at present there are only two syste:ns in which these
_ methods have been implemented for inputting information into control computer sys-
tems from pneumatic transmitters.
Cme such system is called the ASTRA-01 [5]. It is used for multichannel in;:ut of
information from pneumatic transmitters into a control computer system. The system
cail be used with the lOlOV, M-6000, SM-1 and SM-2 control computer systems with
the availability of the appropriate software developed in setting up the automated
, process control system. The system output signal is an electrical 16-bit binary
- cocie. A control computer system controls the system by an electrical 10-bit
_ binary code. The principle of system operation is based on the method of scanning
the channels in the space of the parameter. The input channels are permanently
connected to the individual comparison circuits. In one conversion cycle, the in-
put signals of all channels are compared to a common saw-toothed balancing signal.
The output signals of the comparison circuits are converted into time intervals
proportional to them that are converted into codes by using the control computer.
1'he system has a modular structure and fits in a standard cabinet.
ASTRA-Ol System Specifications
Basic error in measuring pneumatic signals as a percentage of
the range of variation of input signals, no more than +1.5
Mlximum number of pneumatic inputs 120
'1'irne t:or polling 120 pneumatic channels, in seconds 15-40
Prototype ASTRA-01 systems are in operation in the nitron and monomer shopG of a
chemical plant.
'Me shortcoming in the system is the long transmitter polling time, just as in the
inCormation input systems using the PK-3 pneumatic switches. In this system, it is
difficult to implement metrological monitoring of the information channels since
tiere only the control computer system itself can be the metering device.
