摘要: 针对印染机械多电机传动中传统同步控制系统松紧架多而造成设施故障率高,使用维护不方便和维修工作量大的情况,论述减少或取消松紧架的原理和方法,研究采用变频技术和计算机网络技术实现无松紧架和无张力传感器的数字化给定控制多电机同步调速方案,简化了同步系统结构,提高了系统的可靠性和稳定性。给出了由IPC通过RS-485总线控制变频器调速取代传统直流调速的多电机同步控制系统实例,其运行结果证明该方案是成功有效的。

Abstract: Traditional synchronous control systems in multi-drive dyeing and printing machines have too many drawing frames,which leads to frequent malfunction,effort-taking operation and painstaking maintenance.The article probes into principles for a solution to these problems and presents a design for a multi-drive synchronization speed control system with no or fewer drawing frames and tension sensors.The system is based on frequency conversion and computer network technologies.Its digital control over multi-drive speed regulation simplifies the synchronization system and provides higher reliability and stability.In the actual design of such a system,the IPC controls the frequency inverter via RS-485 bus in replace of the traditional DC speed-control system with multi-drive control system.The smooth operation proves that this system is successful and effective.
