单片机控制器在卷染机中的应用

将卷染机的控制系统从直流电机拖动、自耦调压器有级调速改造为交流电机拖动和变频器无级调速。通过对调节对象的理论分析，得到了一种新的控制策略，研制出以单片机为核心的控制器，在不使用速度和张力传感器的条件下，控制系统可自动对被染织物进行恒速与恒张力控制，以利于染色质量的稳定和提高。经实际运行表明，该系统运行可靠，节能增效显著。
关 键 词 卷染机; 变频调速; 单片机; 恒张力控制; 恒线速度控制

Abstract To change the traditional control system of dyeing wind machine from DC motor driving and autotransformer to a new model by AC motor driving VVVF and Single-Chip computer controller (SCCC) was described. By theoretical analysis to regulated object, a new control tactics and controller by take Single-Chip computer as core were obtained and developed. Under the condition of no any analog transducer such as velocity and tension, the dyeing fabric in the control system can be controlled by permanent velocity and tension automatically in order to stabilize and increase the dyeing quality o fabric. The more than two years application of control system shows obvious reliability and save on power energy.
Key words dyeing wind machine; regulate speed by transducer; single-chip computer; control by permanent tension; control by permanent velocity
