本科毕业设计（论文）基于S7-200的纺织设备数据采集子系统设计摘要近年来，我国纺织机械行业的信息化水平有了明显的提高，在新型纺织机械上普遍采用了自动控制技术。随着这些技术的推广应用很大程度提高了纺织行业的工作效率和管理效能。但是对于一些工厂的部分旧设备，要想实现数据的集成就需要另外配置数据采集子系统进行纺机设备的生产数据的获取。本文采用的现场总线对于纺织行业信息化的主要作用是通过高速、稳定、高集成性的数据通信网络，不断的进行数据交换，做到设备的生产数据采集，实现车间工序的数据集成。为了实现这种作用本文采用PROFIBUS-DP现场总线技术，通过每台S7-200增加一个PROFIBUS-DP扩展模块EM277作为从站连接到DP网络中。底层旧设备通过传感器将运动信号传递给S7-200 PLC，通过S7-200进行设备机台的生产工艺参数运算，最后通过EM277进行数据集成。S7-300作为DP主站通过以太网模块（CP343-1）连接到以太网，实现对纺织所需数据的传输，实现分布式、现场化和抗干扰性能的提高，实现生产过程的自动化、智能化，完成纺织机械与现代先进控制技术的结合，为纺织企业的信息化从设备层打下坚实的基础。关键词数据采集纺织系统总线技术EM277 S7-200PLC自动化TEXTILEEQUIPMENT BASEDON S7-200 DATA ACQUISITION SUBSYSYTEM DESIGNABSTRACTIn recent years, the information level of textile machinery industry in China has been significantly improved, the automatic control technology is widely used in textile machinery. With the popularization and application of these technologies greatly improve the efficiency of the work efficiency and the management of the textile industry. But for some old equipment of some factory, integrated to realize the data will need to get production data of textile machinery additional configuration data acquisition subsystem.The main function of Fieldbus used in this paper for the textile industry information is through the data communication network of high-speed, stable, high integration, continue to carry out the data exchange, so that equipment production data acquisition, implementation of workshop process data integration. In order to achieve this effect using PROFIBUS-DP field bus technology, through each S7-200 adds a PROFIBUS-DP extension module EM277 as the station is connected to the DP network. The old equipment through the sensor motion signals to the S7-200 PLC, production process parameter operation equipment through S7-200, finally through the EM277 for data integration. S7-300 as DP master station through the Ethernet module (CP343-1) connected to the Ethernet, and realize data transmission required for textile, distributed, on-site and anti-jamming
