Increase of efficiency and productivity of researches, receipt of
high-fidelity results of experiments, requires planning and standardization of
design of automation scheme of manufacture [1]. Development of difficult
technological processes must be accompanied by stage-by-stage theoretical
research and planning dynamic indexes of control system of the designed object
and their experimental verification on the basis of programmatic, technical
facilities of computer technique. The preliminary planning of productive
process is the basic project task of designer on the stage of his preliminary
development. Thus complex works must decide on creation of corporate InfoBase
with the subsystems of the technical, algorithmic, programmatic providing [2]. By means of analysis of functions of the
special programmatic and technical facilities of the corporate informative
system it should be noted that they in an insufficient measure provide project
procedures of the flexible planning of the automated manufacture owing to
absence of information retrieval queries, optimal choice and necessary computer
researches for determination of exact technological parameters.
In this
connection, in the article the problem of creation of architecture is examined
tool for providing of stage-by-stage choice and planning control system and
control of technological operations of the manufacture.
As an object
of research the manufacture of dispersion drying, providing process exchange of
heat and mass in disperse area, is considered. For planning intelligence functions
the composes scheme of control system of the manufacture is proffered (fig. 1).
The
functions of control system of this manufacturing process are planned on the
basis of the automated following: taking temperature of drying vehicle;
measuring of humidity of composition, that acts on an entrance pipeline;
measuring of humidity of cleansing mixture; treatment measurable melon and
conclusion of output signals from all devices to the screen of monitor of
operator (fig. 1).
Fig. 1.
For an
operationability and flexibility of the executable automated procedures of control
system of the manufacture of dispersion drying
is connected in a central control block (CCB) with a general
dialogue programmatic interface [3]. On
the basis of the special programmatic-informative system CCB provides the
corporate co-operating with the automated manufacture module of the purpose
of reception of devices on the screen
of monitor of operator.
Reliable works of control system of the
manufacture of dispersion drying the block of processing of measurable data and
conclusion of output signals is supported by the system of monitoring of
temperature and humidity. Automation of management and control of temperature
and humidity of the manufacture comes true on the basis of technical and
programmatic equipments of jigging, treatment, visualization and communication
of current data. Temperatures of drying vehicle given from digital of
sensor, sensor of humidity of
composition and sensor of humidity of cleansing mixture written down on flash
cart in a table for every temporal segment. Thus sensors unite with a logical controller
of digital and analog input/by a conclusion and vehicle serial port.
Programming will be realized through USB port without connection of additional programmatically.
On the next stage a microcontroller unites with the module for maintenance of given, temperatures got from
sensors and to humidity on flash cart for subsequent treatment.
For providing of trouble-free work of
the system a standard library is used in logical controller. Thus connection of
data from the sensors of temperature and humidity and record of them come true
in a text file. Sensors are connected to the analog entrance. Data of analog
port are entered in the programmatic code of the system, the module for
maintenance of given, temperatures is initialized cart, the new file of record
of data is opened or created from the sensors of temperature and humidity,
testimony of measuring of temperatures and humidity, record of results in a
file and in port.
Getting temperatures and from sensors it is hatched humidity of
production of the dispersion drying on the screen of pickboard. At the input of
values of temperature and humidity in serial port of computer the basic
technical parameters of sensors are determined depending on the specific of
this production. The conclusion of data on the screen of pickboard is managed
on an interface. Cooperation of work of sensors and screen provided by means of
sketch that measures and sends the temperatures given about the state and to
humidity in this manufacture.
