【摘要】：随着内燃机的诞生和现代工业的发展人类对石油及其制品的需求量讯速增长,石油在现代社会起着越来越重要的作用。目前的石油开采主要通过抽油机来进行,所以抽油机的工作状况直接影响到石油的产量,对抽油机载荷及位移的数据监测是判断抽油机工作状况的重要依据。现有的抽油载荷及位移直接测量方法多少都存在变送器损坏频繁和工序复杂等不足,因此改进抽油机载荷及位移测量方法对及时发现抽油机运行中的问题、提高原油产量有着重要意义。本文设计了一种有别于传统方法的抽油机载荷及位移采集系统,本系统由载荷及位移一体变送器、手持器和数据传输终端DTU三部分组成。安装在抽油机上的载荷及位移一体变送器定时采集并存储抽油机的载荷及位移数据,同时将数据发送到数据传输终端DTU, DTU接收并存储数据后再通过GPRS模块将数据发送到接入互联网的上位机中。手持器用于对载荷及位移一体变送器进行配置,以适应复杂的现场情况。硬件采用低功耗的设计思路,在满足系统性能的前提下采用了MSP430单片机作为MCU,设计了信号处理、数据存储、太阳能充电等模块,保证了系统的功能。系统软件在IAR环境下用C语言进行开发,使用模块化的思路,在实现各模块功能的前提下,又兼顾系统的总体协调,保证了系统的整体运行。经过在实验室的调试和抽油现场的检验,表明本系统能够实时、可靠地采集和传输抽油机的载荷及位移数据,上位机将接收到的数据进行功图绘制后可实时判断抽油机的工况。本系统具有工作性能稳定、成本低等优点,能够良好适应抽油现场恶劣的环境,具有较高的实用价值和广泛的应用前景。
[Abstract]:With the birth of internal combustion engine and the development of modern industry, the demand for oil and its products is increasing rapidly, and oil plays a more and more important role in modern society. So the working condition of the pumping units has a direct impact on the output of oil. The data monitoring of load and displacement of pumping unit is an important basis for judging the working condition of pumping unit. The existing direct measuring methods of pumping load and displacement have many shortcomings, such as frequent damage of transmitter and complicated working procedure, etc. Therefore, it is very important to improve the load and displacement measurement method of pumping unit to find out the problems in the operation of pumping unit in time and to increase crude oil output. In this paper, a collection system of load and displacement of pumping unit is designed, which is different from the traditional method. The system consists of a load and displacement transmitter, a handheld transmitter and a data transmission terminal (DTU). The load and displacement transmitter installed on the pumping unit collects and stores the load and displacement data of the pumping unit at regular intervals. At the same time, the data is sent to the data transmission terminal DTU, the DTU receives and stores the data, and then sends the data to the host computer connected to the Internet through the GPRS module. The handheld device is used to configure the load and displacement integrative transmitter. In order to adapt to the complex field situation, the hardware adopts the low power consumption design idea, under the premise of satisfying the system performance, adopts the MSP430 single chip computer as the MCU, designs the signal processing, the data storage, the solar energy charging module, etc. The system software is developed in C language under the environment of IAR, and the idea of modularization is used. On the premise of realizing the function of each module, the overall coordination of the system is also taken into account. The whole operation of the system is ensured. After the debugging in the laboratory and the inspection of the pumping field, it is shown that the system can collect and transmit the load and displacement data of the pumping unit in real time and reliably. The system has the advantages of stable working performance and low cost, so it can adapt to the harsh environment of pumping field. It has high practical value and wide application prospect.
