【摘要】：随着我国油田数字化逐步向智能化不断迈进,基于物联网的油气生产监控系统已成为各大油田智能化建设的主要趋势。数字化与智能化油田井场生产监控的关键是井场数据采集、传输及控制,其核心是井场远程终端设备(RTU,Remote Terminal Unit)。因此,研制油井智能RTU在数字化与智能化油田监控具有重要的现实意义和应用价值。针对数字化与智能化油田井场监控技术特点,结合辽河油田数字化井场监控系统项目要求,对油田井场生产工艺与井场监测设备以及数字化井场监控系统进行分析,确定油井智能RTU功能需求与技术指标。研制以ARM嵌入式系统为核心的RTU,智能RTU具有主从站工作模式,通过ZigBee实现主从RTU多井自组网。硬件上,采用STM32F407ZET6、ZigBee与以太网通信模块,进行采集与控制电路、通信电路以及数据存储电路设计。软件上,采用移植UC/OS-II操作系统,开发下行任务、上行任务、PC通信任务、数据存储任务及智能报警及控制任务等子程序,实现A11-GRM协议的多端口通信。最后,进行智能RTU的软硬件调试与运行测试,完成了智能RTU的应用功能与效果分析。实际应用表明,油井智能RTU能够准确采集油井仪表数据并传输至生产监控中心,实现了主从RTU多井自组网及A11-GRM协议的多端口通信,并支持故障报警及控制,在数字化与智能化油田井场监控系统中发挥重要作用。
[Abstract]:As China's Digital Oilfield gradually to the intelligent monitoring system of developing, network of oil and gas production has become the main trend of major oil fields of intelligent building based on key digital and intelligent oil field production monitoring is the field data acquisition, transmission and control, whose core is the site of remote terminal (RTU, Remote, Terminal Unit). Therefore, the well developed intelligent RTU has important practical significance and application value in the digital and intelligent oil monitoring. According to the digital and intelligent oil well monitoring technology, combined with the project of digital well monitoring system in Liaohe Oilfield, the oil field production process and site monitoring equipment and digital well monitoring system was analyzed and determined wells intelligent RTU functional requirements and technical indicators. Using ARM as the core of the embedded system RTU, intelligent RTU has subordinate station work mode Type, through the realization of ZigBee master-slave RTU multi well ad hoc network. The hardware, using STM32F407ZET6, ZigBee and Ethernet communication module, acquisition and control circuit, communication circuit, data storage circuit design. Software, the transplant UC/OS-II operating system, development of downward, upward, PC communication tasks, tasks of data storage and intelligent alarm the task and control subroutine, multi port communication A11-GRM protocol. Finally, the debugging and running test of hardware and software of intelligent RTU, completed the analysis of application of intelligent RTU function and effect. The practical application shows that RTU can accurately collect wells wells intelligent instrument and transmit data to the production monitoring center, multi port communication is realized RTU master-slave multi well network and A11-GRM protocol, and support fault alarm and control, play an important role in the field of monitoring system for the digital and intelligent oilfield.
