In the system, a lot of problems existing in distributed oilfield for a long time can be solved, such as rough measuring method, poor realtime performance and high manmade errors. With the help of alarming system, oiltheft 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: remotemonitoring terminal and putermonitoring center. Remotemonitoring 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 work. Computermonitoring center achieves logging on Inter website through fixed IP to plete some functions such as data receiving, saving and analysis, the realtime 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 remotemonitoring terminals. According to system function， hardware is divided into such five modules as data acquisitions module, GPRS munication module, image acquisition module, keyboard and display and power supply modules. The core of data acquisition module is ARM39。s latest CortexM3 processor STM32F103C6T6, which is in charge of the whole 基于 GPRS 的分布式油田原油計(jì)量和防盜系統(tǒng)設(shè)計(jì) V control of monitoring terminals. GPRS module is posed of BenQ39。s M23A GSM/GPRS modules and related peripheral circuits, which is responsible for sending and receiving data. Image acquisition module transforms the video signal into digital signal. Keyboard and display module implement display and operation of the terminal. And power supply module achieves power provision of the whole terminal equipment. In the paper circuits of data acquisition module, GPRS munication module and keyboard module are described in detail. During the remotemonitoring terminal software design, software design is built in the hierarchical design way which have been using in realtime operating system software develop ed. Generally speaking, the whole remotemonitoring terminal software design uses hierarchical software design, and then bines with finitestate machine and takes advantage of casedriven last. System software programming idea is introduced firstly, and then driver program and application layer programs of monitoring terminal are described in detail. Finally, a brief description of software design of puter monitoring center is given in the paper.
