醋纤生产装置数据采集系统的设计与实现

摘要

The electrical parameters of motor in the acetate fiber production site, e. g. , current, voltage, power energy, etc. , are significant to product quality analysis and production arrangement, so collecting the electrical parameters of the motor is one of the critical parts in production process. In combinalion with the specific requirement to the data acquisition, the acquisition system is analyzed, and designed as well as implemented on-site. The S7-400 is applied to read the parameters of field networking instruments and inverters, and the AnyBus gateway is used to implement the transformation between the Modbus and Profibus protocols. The data acquisition system based on this design concept can be stably applied into the production site, and bring good production benefit.%醋酸纤维生产现场电机的电流、电压、电能等电力参数对产品质量分析和生产安排都具有重要的指导意义,因此对电机电力参数的采集是生产环节中至关重要的一部分.结合生产中对数据采集的具体要求,对采集系统进行了分析设计以及现场实现；采用S7-400读取现场网络仪表和变频器的参数,并使用AnyBus网关实现Modbus与Profibus协议转换.基于该设计思想的数据采集系统能够平稳地运用到生产现场,并能带来良好的生产效益.
