摘要
针对目前沥青搅拌站控制系统的不足、结构复杂、现场设备分散、接线繁杂及系统实时性差等问题,根据产品生产工艺流程,系统硬件设计采用三菱Q00UCPU、CC-Link主站模块QJ61BT11N等设备,辅以变频调速,高精度的传感器,可靠的数据通讯设备,多种信号通过分布式I/O组件和CC-Link传送至PLC进行处理;软件上设计了搅拌站的监控系统和现场设备的通讯接口,使用人机界面实现设备的远程控制,操作方便,工作稳定,降低了成本,提高了生产效率;该系统经过实际现场生产,总线通讯正常,累计生产超过8 000吨料,超过40h无故障。
The control system of asphalt mixing plant have the current shortage, complex structure, decentralized field devices, wiring complexity, and poor real--time system. According to the production process, Mitsubishi Q00UCPU, CC--Link master module QJ61BTllN and other equipments are used in the system hardware design, supplemented with variable speed, high--precision sensor and reliable data communication equipments. Varieties signals via distributed I/O components and CC--Link are transferred to the PLC for processing. The mixing station monitoring system and field devices communication interface are designed in software. Using the HMI device to achieve remote control, easily operating, stable, reducing costs, improving production efficiency. The system is applied on--site production, bus communi- cation is normal, the cumulative production exceed 8000 tons material, and more than 40 hours without failure.
