In the system, a lot of problems existing in distributed oilfield for a long time can be solved, such as rough measuring method, poor real-time performance and high man-made errors. With the help of alarming system, oil-theft criminals will be reduced. The aim of the whole system is to improve the informatization management level of distributed oilfield. The system contains two parts: remote-monitoring terminal and computer-monitoring center. Remote-monitoring terminal collects data of crude oil level in oil tank, valve’s status and images surrounding the oil tank when the burglar alarm equipment is triggered. Finally data are sent and received via GPRS wireless network. Computer-monitoring center achieves logging on Internet website through fixed IP to complete some functions such as data receiving, saving and analysis, the real-time display of crude oil level in oil tank, current valve’s status and report forms printing. In order to ensure flexible configurations of the whole hardware and make it debug easily and maintenance simply, modularization design method is adopted in hardware design of remote-monitoring terminals. According to system function，hardware is into such five modules as data acquisitions module, GPRS communication module, image acquisition module, keyboard and display and power supply modules. The core of data acquisition module is ARMs latest Cortex-M3 processor STM32F103C6T6, which is in charge of the whole control of monitoring terminals. GPR
