Abstract

An online dyeing feedback control system comprises a temperature sensor, a multi-factor dye-uptake module, an online monitoring controller and a temperature regulating controller. The temperature sensor is used for detecting the working temperature in a reaction kettle. The multi-factor dye-uptake module is used measuring and calculating the dye-uptake according to the working temperature, the salinity and the bath ratio. The online monitoring controller is used for comparing dye-uptakes obtained in real time with a set dye-uptake to obtain errors and error variable quantity and obtaining a temperature change value according to the errors and the error variable quantity. The temperature regulating controller is used for comparing the temperature change value and a current working temperature to obtain a temperature regulating value and controlling a heating system of the reaction kettle to work according to the temperature regulating value. The invention further provides an online dyeing feedback control method. The online dyeing feedback control system and method realize online feedback control and is high in control precision and working efficiency.

Description

technical field [0001] The invention belongs to the field of automatic control in the printing and dyeing industry, and relates to an online dyeing feedback control system and a method thereof. Background technique [0002] At present, the textile printing and dyeing industry, which is a traditional industry in my country, has been developing rapidly. Although its output is increasing year by year, its benefits are not satisfactory. The fundamental reason is that the rapid development of the printing and dyeing industry is accompanied by high energy consumption, high pollution discharge and high water consumption. Therefore, it is necessary to apply high technologies such as automation technology and modern electronic technology to the printing and dyeing industry, and actively research new technologies and new processes in the printing and dyeing industry, so as to change the growth mode of the traditional printing and dyeing industry, achieve the purpose of reducing energy...
