Using DSP To Design Embedded Oil Well Logging System

With the putting forward of the concept of Internet of Things,its uses are constantlyexpanded.Now,the Internet of Things has been used in industrial detection,buildingcontrol system, familial intelligent device, mobile terminal, video monitoring systemand railway monitoring system and other areas,and its principe can be used in the designof logging system.The major research direction of this dissertation is the datatransmission and control system of the embedded logging system which is based onDSP processor.The logging system includes three parts which are data acquisition andtransmission system(lower computer),data transmission and testing system(uppercomputer) and data monitoring center(server).The lower position machine has two modules which are data acquisition and datatransmission. The data acquisition module can collect data through sensors which areused for logging and AD module. The data transmission module transmit the collecteddata out through CAN bus. The major function of the upper computer is to receivedata,packet data and transfer the received data to the server.The server can receive datafrom many upper computers at the same time,and then analyse,manage,store anddisplay them.The upper computer’s major function is receive data from lowercomputers through CAN bus,packet them,then transfer the packing data to the server.The dissertation mainly introduced the whole framework of the system and thedesign of the upper computer.The hardware of the upper computer consist of theminimum system of the TMS320F2812,CAN Communication Module,EthernetCommunication Module Electronic disk storage module and so on. The dissertationtransplants the RTOS(real-time operating system) μC/OS-II, Based on this,itimplements the teaming work of Ethernet protocol stack, FAT file system and CANcommunication module.
