【摘要】：本课题是在国内油田信息化大环境下,东北大学电力系统与电力传动研究所为辽河油田某油井开发的油田抽油机综合管理系统的下位机远程监控终端部分。 本文分析了国内外油田监控行业的现状及存在的问题,结合油田现有监控终端存在的问题与本项目用户实际需求,以游梁式抽油机为研究对象,设计了一台兼具抽油机光杆示功图绘制与抽油机驱动电机电参量测量功能的无线抽油机监控终端。本终端以高性能的数字信号处理器为主控芯片,采用新型无线传感器技术、无线数据通信技术,配合专用电能计量芯片,实现对油田抽油机多种参数的实时测量、显示和远程通讯。有故障报警时亦能主动将报警信息上传至监控中心,便于油井工作人员及时掌握生产情况,利于科学管理。 文中分模块对本监控终端具体的器件选型和软硬件设计进行了介绍,主要分为三大模块：示功图采集模块、电参量测量模块和外围串口设备扩展模块。在示功图采集模块中选用了一款无线载荷位移一体化传感器,实现了示功图载荷、位移信息采集的无线化,对功图采集的软件设计流程进行了详细介绍；在电参量测量模块,以专用电能计量芯片ADE7758为核心,进行了硬件电路的设计,重点讲解了DSP与ADE7758之间的SPI通讯；在外围串口设备模块部分,进行了人机界面的设计,Zigbee无线通信模块的选型,因为本系统所接串口设备数量超过了主控芯片的串口数,故本文一并对通用异步接收／发送(UART)接口的扩展进行了研究与设计,无论对系统现阶段设计目标的实现还是将来的扩展都有一定的研究意义。 本设计可以广泛应用于油田有杆抽油设备的监控,使油田巡检工人从繁重的体力劳动中解脱出来,也避免了手工绘制示功图的不准确性,对于抽油机的运行管理由粗放型向精细型转化具有一定的实际应用价值和现实意义。
[Abstract]:In the information environment of domestic oil field, the electric power system and electric power transmission research institute of Northeast University is the part of the remote monitor and control terminal of the oil pumping unit integrated management system developed for a oil well in Liaohe Oilfield. This paper analyzes the present situation and existing problems of oil field monitoring industry at home and abroad, combines the problems existing in the existing monitoring terminals of oil fields and the actual needs of the users of the project, and takes the beam pumping units as the research object. A wireless pumping unit monitoring terminal is designed, which has the functions of drawing the light rod dynamometer and measuring the electric and electromechanical parameters of the pumping unit. The terminal takes the high performance digital signal processor as the main control chip, adopts the new wireless sensor technology, wireless data communication technology and the special electric energy metering chip to realize the real-time measurement of many parameters of the oil field pumping unit. Display and remote communication. The alarm information can also be uploaded to the monitoring center when there is a fault alarm, which is convenient for the oil well staff to grasp the production situation in time and be conducive to scientific management. In this paper, the specific device selection and hardware and software design of the monitoring terminal are introduced in detail, which are divided into three modules: the indicator diagram acquisition module, the electrical parameter measurement module and the peripheral serial port equipment expansion module. In the indicator chart acquisition module, a wireless load displacement integrated sensor is selected to realize the wireless collection of the power chart load and displacement information. The software design flow of the work graph acquisition is introduced in detail. In the electrical parameter measurement module, the hardware circuit is designed with the special energy metering chip ADE7758 as the core. The emphasis is on the SPI communication between DSP and ADE7758. In the peripheral serial port equipment module, the design of the man-machine interface and the selection of the Zigbee wireless communication module are carried out, because the number of serial devices connected in this system exceeds the serial port number of the main control chip. Therefore, this paper also studies and designs the extension of the universal asynchronous receiving / transmitting (UART) interface, which has a certain significance for the realization of the present design goal and the future extension of the system. This design can be widely used in the monitoring of oil field sucker rod pumping equipment, thus freeing the inspection workers from the heavy physical work, and avoiding the inaccuracy of manually drawing the indicator diagram. It has certain practical application value and practical significance for the operation management of pumping unit from extensive type to fine type.
