[Abstract]:Field monitoring is always an important measure to ensure oilfield production and its management, especially for the distributed and remote oil fields in China. With the rapid development of RTU (remote Control Terminal) technology, oil field monitoring has gradually entered the stage of digitization and intelligence. Depending on the RTU system of oil field to monitor the production state of oil field, it is advantageous for the staff to discover the problems in the production process in time, and to help the manager to adjust the production work plan. Therefore, it is of great significance for the design and research of oilfield RTU system. In view of the fact that the monitoring of equipment status and the acquisition of production data in most oilfields are in manual stage, it is difficult to find and eliminate the equipment failure in time, and the production data can not report the production status of this oilfield to the superior in real time. In this paper, an oilfield RTU system based on arm is designed and developed. The main research contents are as follows: first, this paper summarizes the research status and application technology of RTU system at home and abroad, according to the working principle and characteristics of RTU system. The overall design scheme of the system is put forward, which is based on the high performance microprocessor and the effective data processing algorithm to realize the data monitoring in the oil field. Second, the paper discusses some key technologies in the system design: according to the real-time requirements of oilfield monitoring, the real-time planning of some data acquisition and data communication, aiming at the reliability of oil field monitoring, The system designs anti-interference in both hardware and software, and proposes an improved digital filtering algorithm for the accuracy of data acquisition. Thirdly, the paper gives the detailed design process of hardware and software of RTU slave station in oilfield RTU system based on arm, that is, the hardware system takes STM32F103VET6, which has excellent performance in arm system, as the control core, and the main circuit module includes analog input and output module. Digital input / output module RS232 module RS485 module, memory module, power supply module, etc. The software system is developed on the platform of Keil uVision4, and the software program of each module is designed in combination with hardware circuit, which has good expansibility. The 渭 C / OS-II operating system is transplanted into the system, which improves the real time and reliability of the system. Fourthly, the paper tests the function of RTU slave station in the designed oilfield RTU system. Based on Modbus Poll software platform, the paper debugs each module of the system, and verifies the reliability, stability and good practical value of the system.
