The Research Of Consuming Diesel Oil Data Acquisition And Transmission System Based On C8051F310

Along with the broad application of ultrasonic flow measurement technology,GSM communication technology and embedded system technology,such development trend is being formed as intellectualization,networking and information for drilling job.Also,the digital fuel management is an important part of digitalized drilling.Analysis and research are conducted in this paper on ultrasonic flow meter deployed on drilling site and a set of fuel consumption acquisition data and transmission system based on C8051F310 is designed by virtue of currently popular C8051F310 microprocessor,serial port expansion chip GM8125,GPRS module and 485 bus chip SN75276.Such system can conduct real-time monitoring on fuel consumption of major equipments deployed during drilling, acquire and process such monitored results through industrial 485 bus,store them on the embedded measuring terminal system and then transmit them to the Monitoring Center of Drilling Company through GPRS network in real time.Detailed information has been introduced in this paper to the hardware compositions and their functions in the system,the designs of core control unit and interface unit are completed and the whole system software flowchart and partial subprogram flowchart are presented.The system has high precision data acquisition and remote control and processing abilities and strong actual application value.The practices have proven that the system is stable and reliable and is convenient and flexible to operate and has achieved the forecasted results.
