【摘要】：本課題是在國內(nèi)油田信息化大環(huán)境下,東北大學電力系統(tǒng)與電力傳動研究所為遼河油田某油井開發(fā)的油田抽油機綜合管理系統(tǒng)的下位機遠程監(jiān)控終端部分。 本文分析了國內(nèi)外油田監(jiān)控行業(yè)的現(xiàn)狀及存在的問題,結合油田現(xiàn)有監(jiān)控終端存在的問題與本項目用戶實際需求,以游梁式抽油機為研究對象,設計了一臺兼具抽油機光桿示功圖繪制與抽油機驅(qū)動電機電參量測量功能的無線抽油機監(jiān)控終端。本終端以高性能的數(shù)字信號處理器為主控芯片,采用新型無線傳感器技術、無線數(shù)據(jù)通信技術,配合專用電能計量芯片,實現(xiàn)對油田抽油機多種參數(shù)的實時測量、顯示和遠程通訊。有故障報警時亦能主動將報警信息上傳至監(jiān)控中心,便于油井工作人員及時掌握生產(chǎn)情況,利于科學管理。 文中分模塊對本監(jiān)控終端具體的器件選型和軟硬件設計進行了介紹,主要分為三大模塊：示功圖采集模塊、電參量測量模塊和外圍串口設備擴展模塊。在示功圖采集模塊中選用了一款無線載荷位移一體化傳感器,實現(xiàn)了示功圖載荷、位移信息采集的無線化,對功圖采集的軟件設計流程進行了詳細介紹；在電參量測量模塊,以專用電能計量芯片ADE7758為核心,進行了硬件電路的設計,重點講解了DSP與ADE7758之間的SPI通訊；在外圍串口設備模塊部分,進行了人機界面的設計,Zigbee無線通信模塊的選型,因為本系統(tǒng)所接串口設備數(shù)量超過了主控芯片的串口數(shù),故本文一并對通用異步接收／發(fā)送(UART)接口的擴展進行了研究與設計,無論對系統(tǒng)現(xiàn)階段設計目標的實現(xiàn)還是將來的擴展都有一定的研究意義。 本設計可以廣泛應用于油田有桿抽油設備的監(jiān)控,使油田巡檢工人從繁重的體力勞動中解脫出來,也避免了手工繪制示功圖的不準確性,對于抽油機的運行管理由粗放型向精細型轉(zhuǎn)化具有一定的實際應用價值和現(xiàn)實意義。
[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.
