目前染色工艺中普遍采用常规仪表控制高温高压染色机,但是由于常规仪表控温水平不高,不能保持最佳染色质量,有时还因高温高压染锅内温度、压力骤增,系统失控发生喷顶等事故.为此,我们设计了微机控制高温高压染色机.该系统由一台BCM-81单板机作主机,并配有ADC和DAC、驱动及报警电路等,具有检测、报警、显示、控制等功能.在采用误差自动修正、数字滤波等软件技术后,提高了系统的精度、抗干扰能力和可靠性.系统输入信号取自温度传感器和压力传感器.染锅内的温度和压力经变换、放大后,得
Currently dyeing process commonly used conventional instrument to control high temperature and high pressure dyeing machine, but due to the conventional instrument is not high temperature control, can not maintain the best dyeing quality, and sometimes due to high temperature and pressure stained pot temperature, pressure surge, the system out of control roof We designed a computer controlled high temperature and high pressure dyeing machine.The system consists of a BCM-81 single-board machine as the host and is equipped with ADC and DAC, drive and alarm circuits, etc., with the detection, alarm, display, Control and other functions in the use of automatic error correction, digital filtering and other software technology to improve the system accuracy, anti-interference ability and reliability of the system input signal from the temperature sensor and pressure sensor dye pot temperature and pressure by the transformation After zoom in, too
