溢流染色机网络化监控系统设计

Designing of networked monitoring system for overflow dyeing machines

为解决传统溢流染色机染色时人为因素严重影响染色工艺的一致性、染色质量、单位产品的能耗等问题,设计一种溢流染色机网络化监控系统。通过将各染色机控制器作为下位机,采用RS485总线进行组网,并配置了上位控制器及系统监控软件,实现对各染色机的工艺参数下达、运行状态的远程动态显示、历史数据保存、故障分析等集中监控功能。应用测试结果表明,在系统监控下不同染色机的最大染色误差在0.5%以内,织物的上染时间缩短5～8 min,按实验举例分析,能耗可比原来降低15%。

In conventional processing using overflow dyeing machines,the consistency of dyeing technology,the quality of dyed products,and the energy consumption per unit are seriously affected by human factor.To solve these problems,a kind of networked monitoring system for overflow dyeing machines was put forward.In this system,by being networked with each others through RS485 bus,the dyeing controllers were utilized to be slave controllers.The master control computer with system monitoring software was configured.The centralized monitoring functions of sending down the parameters of dyeing production technology to dyeing machines,remote display of dynamical running status,saving of historical data,and error analysis were realized.It is approved by the test case that the maximum dyeing errors can be controlled in 0.5%,dye uptake time and power consumption can be reduced by 5-8 minutes,15%,respectively.
