Control System

Objectives of Control system:

Control SystemThese days dyers are relying more and more on digital process control system to increase efficiency and product quality along with reduction in utility and production costs. Using a reliable control system, variables like temperature is controlled automatically and accurately.

In the dyeing process, there is a great challenge to control the temperature of a dye bath. The control system used for monitoring and maintaining temperature must be capable of performing the task of balancing heat transfer with accurate control.
Process control is regarded as a one of the most vital aspects of quality assurance operation. For example in the case of textile operations, like batch dyeing, there could be many variables which are under the control of dyer's, but there would be many more that are not. Typically these factors interact in a a complex way. That is the reason why a dyehouse having its eye on future must have better process control systems. Recently control hardware has made great advancements. The emergence of cheap, dynamic, high speed digital micro-processors has made easy different dyeing applications. Micro-processor hardware has been now developed to a very high state of performance and reliability.

A typical control system includes micro-processors that has:
  • Control algorithms along with interfaces
  • A state of the art multichannel l/O that comes with two way digital/ analog conversion
  • Having communication abilities that are both synchronous and asynchronous
  • Monitoring and sensors, that comes with interfaces
  • Process devices (e.g. pumps, valves)
  • Networking capabilities upload/download
The Control unit shown in the diagram consists of a Computer that has a very latest advanced touch screen user interface. It also consist of a main control unit or MCU. The dyeing programmes and other necessary parameters are loaded completely into the MCU. The MCU automatically controls the program. It runs in tandem with the PLC-control unit. Which effectively means that the machine can function independently of the computer. The control system is totally networked to the main automation control station, so that there can be easy inter-access of data along with the option of operational accessibility.
