【摘要】：随着物联网概念的提出，其用途不断的扩展，现在已普遍的应用到工业检测、楼控系统、家庭智能设备、移动终端、视频监控系统和铁路监控系统等各个领域，在测井系统设计中也可以运用物联网的原理。本文的主要研究方向为基于DSP的嵌入式石油测井系统中的数据传输和控制部分。根据物联网的设计理念，本测井系统可分为三部分,分别是井下数据采集和传输系统（下位机）、地面数据传输和检测系统（上位机）、数据监控中心（服务器）等。 下位机是由数据采集和数据传输两个模块组成，数据采集是通过各种测井需要的传感器和AD模块配合进行数据采集，而数据传输是运用CAN总线将采集到的数据发送出去。服务器可以接收多个下位机传输的数据，同时完成数据的分析、管理、存储和显示等。上位机的主要功能是通过CAN总线接收下位机的数据，然后数据打包后通过TCP/IP协议传输给服务器。 论文主要介绍了该系统的整体构架和上位机的实现。上位机的硬件电路的设计主要包括TMS320F2812的最小系统、CAN通信模块、以太网通信模块、电子盘存储模块等。本系统在TMS320F2812芯片上移植了μC/OS-II实时操作系统，，并在此基础上实现以太网协议栈、FAT文件系统、CAN通信等各个功能模块之间的协调工作。
[Abstract]:With the introduction of the concept of the Internet of Things, its use has been expanding, and now it has been widely used in industrial detection, building control system, home intelligent equipment, mobile terminals, video surveillance system and railway surveillance system and other fields. The principle of the Internet of Things can also be used in the design of logging system. According to the design concept of the Internet of Things, the logging system can be divided into three parts: downhole data acquisition and transmission system (slave computer), ground data transmission and detection system (upper computer), data monitoring center (server).
The slave computer is composed of two modules: data acquisition and data transmission. Data acquisition is carried out by the cooperation of various sensors and AD modules required by logging. Data transmission is to send the collected data out by using CAN bus. The server can receive data transmitted by multiple slave computers and complete data analysis and management. The main function of the upper computer is to receive the data of the lower computer through CAN bus, and then pack the data and transmit it to the server through TCP/IP protocol.
This paper mainly introduces the whole frame of the system and the realization of the host computer.The design of the hardware circuit of the host computer mainly includes the minimum system of TMS320F2812, CAN communication module, Ethernet communication module, electronic disk storage module and so on.The system transplants the real-time operating system of Mu C/OS-II on the chip of TMS320F2812 and realizes on this basis. The coordination between various functional modules such as Ethernet protocol stack, FAT file system, CAN communication and so on.
