Abstract:

The oil well remote monitoring system is designed by using three-tier structure which includes data acquisition layer, data transmission layer and data processing layer. This paper describes the hardware design and software development of RTM (Remote Terminal Measurement) in acquisition layer in detail. RTM uses ARM processor--STM32F103 as the core controller, connects with the RTU (Remote Terminal Unit) in transmission layer through 485 communication, implements the functions like the automatic detection of the oil well’s production parameters such as the oil pressure and oil temperature, the real-time detection of the pumping pulley’s speed and the remote control of oil well’s starting and stopping. RTM has the characteristics of good compatibility, easy expansion and wide range of applications. The designed system has been applied in oil field which not only can reduce labor intensity and improve work efficiency, but also can detect the abnormalities of wells and take timely measures to guarantee the safe operation of the well production.
