Tools for creating control systems based on the topological method of construction

The topological method is characterized by the ability to integrate automation tools directly into technological equipment. This eliminates the use of a large number of cables and auxiliary structures for their placement. In addition, it ensures full factory readiness of technological units

SMART-CS includes a functionally complete set of basic devices of three types:
control interactive network
three types of interactive network nodes of Smart Control Units (SCU):
- SCU-I - single-channel, for communication with information sources (sensors)
- SCU-U - single-channel, for communication with information receivers (executive mechanisms)
- SCU-M - multichannel, for communication with sources and receivers of information operated in special conditions
Smart Control Stations (SCS) for processing information coming from the penal correction system and developing control actions on actuators in accordance with control algorithms
Actuator Control Units (ACU) for switching power supply

The interactive network is built on the basis of the following interfaces:
• O-BUS optical channel
• data transmission channel over P-BUS power lines

The process of automation of any technological unit consisting of several functionally completed technological units is carried out in two stages:
  • automation of each technological unit
  • integrated automation of the unit as a whole
Equipment of technological units with SCU, SCS and ACU is carried out at the factory, which ensures 100% factory readiness of the equipment
The structural scheme of automation of any technological unit is presented in the figure:

The structural scheme of automation of any technological object as a whole is presented in the following figure:
structural scheme of automation
As can be seen from the figure, the structure of SMARTSAU is regular and scalable

Information and algorithmic interaction of all the above-mentioned devices is carried out via an interactive network, which consists of segments of two types - KA (technological unit segment) and KB (technological unit segment)

Topological design of the automation system is carried out in several simple stages

  • 1
    Determination of the required amount of SCS, SCU and ACU
    The number of SCU-I is determined by the number of sensors
    SCU-U and ACU - by the number of executive mechanisms
    SCS - by the number of technological blocks
  • 2
    Placement of SCU, SCS and ACU on technological equipment
    SCU-I are placed directly on the sensors
    SCU-U and ACU - near the actuators
    SCS - in any convenient place on the technological unit
  • 3
    Laying of power lines
    inside the technological unit
    Power supply lines inside the process unit are laid from the SCS in series by a ring through all the SCU of this technological unit
  • 4
    Laying of power supply lines and communication between technological units
    Power supply and communication lines between different technological units are laid in series by a ring through all SCS of each technological unit
This concludes the development of design documentation for technological equipment in terms of automation

Technical and economic efficiency

  • Ensuring full factory readiness of process units
    Achieved by installing SCS, SCU and ACU at the block manufacturer
  • Reducing the cost of block containers, cables, intermediate terminal boxes, cable glands
    Achieved by installing the SCU and ACU directly on sensors and actuators
  • Reducing the cost and duration of factory tests
    Achieved by testing at the plant with standard automation
  • Improving the reliability of technological equipment
    Achieved by eliminating cables, intermediate terminal connections and connectors
  • Reduction of construction, installation and commissioning time
    Achieved due to full factory readiness of technological units
  • Reducing the cost of cable rack construction and installation work
    Achieved by eliminating a large number of individual cable lines to sensors and actuators and the absence of a central control device
