中文摘要硕士生:申小会(签名) 聋心!垒指导教师:李琳‘签名’—鼋岛卜摘要国内油田电动钻机数字式电控系统多采用西门子PLC作为控制核心,并应用Profibus 现场总线技术实现了西门子PLC与电气传动控制系统和配电控制系统之间的通信功能, 但柴油发电机组控制系统尚没有实现与西门子PLC的通信。为积极完善电动钻机的数字化控制程度,西安石油大学电动钻机重点控制实验室基于TMS320F2812研究开发了柴油发电机组数字控制器。而该单元本身具有CAN总线接口,要实现该数字控制器与西门子 PLC的通信功能,需要开发Profibus和CAN总线协议转换模块。论文首先对电动钻机控制系统做了简单的介绍,对国内外电动钻机的发展现状作了比较,并着重介绍了电动钻机和柴油发电机组的主控单元、Profibus和CAN两种总线技术。接着,给出了该通信单元硬件和软件的设计方法,该通信单元的硬件设计中主要给出了 Profibus和CAN协议转换模块的设计方法,,应用双IEIRAM实现两种总线协议的数据交换;软件设计部分由Profibus和CAN协议转换模块程序,主站控制程序及柴油发电机组控制系统eCAN通信程序组成。最后,将该通信单元在搭建的网络通信平台中加以验证,实验表明:该通信单元可实现主站PLC 对柴油发电机组控制系统的远程控制和监测功能,数据传输可靠性强,速率高,该通信单元的开发可进一步完善电动钻机控制系统的数字化控制程度,具有现实意义。关键词:电动钻机柴油发电机组PLC通信论文类型:应用研究英文摘要 Subjeet: Speciality: Name: Instructor: Communications module development ofelectrically operated drilling machine dieseldynamo control system Detect Technology and Automation Equipment ShenXiaohui(signatll呐已乜幺龇 LiLin(signatu代I fl;2lZ4一——一 ABSTRACT The digital ontrolsystem of theelectric drilling machine almost hasused the Siemens PLC as themain controller,and usedProfibusfieldbustechnology realized munication between Siemens PLC control system and electricaltransmission control system,distribution controlsystem,but the dieselgenerator control system hash’t munication with theSiemens order toimprove thedigital control degree of electricdrillingmachine,the key control laboratory of electricdrillinXi’allshiyou University has developed dieselgenerator digital controller based onTMS320F28 2,which has aCAN businterface,We need todevelop a Profibus and CAN munication protocol conversion unit toachieve munication between digital controllerandSiemens PLC.
