【摘要】：隨著物聯網概念的提出，其用途不斷的擴展，現在已普遍的應用到工業(yè)檢測、樓控系統(tǒng)、家庭智能設備、移動終端、視頻監(jiān)控系統(tǒng)和鐵路監(jiān)控系統(tǒng)等各個領域，在測井系統(tǒng)設計中也可以運用物聯網的原理。本文的主要研究方向為基于DSP的嵌入式石油測井系統(tǒng)中的數據傳輸和控制部分。根據物聯網的設計理念，本測井系統(tǒng)可分為三部分,分別是井下數據采集和傳輸系統(tǒng)（下位機）、地面數據傳輸和檢測系統(tǒng)（上位機）、數據監(jiān)控中心（服務器）等。 下位機是由數據采集和數據傳輸兩個模塊組成，數據采集是通過各種測井需要的傳感器和AD模塊配合進行數據采集，而數據傳輸是運用CAN總線將采集到的數據發(fā)送出去。服務器可以接收多個下位機傳輸的數據，同時完成數據的分析、管理、存儲和顯示等。上位機的主要功能是通過CAN總線接收下位機的數據，然后數據打包后通過TCP/IP協議傳輸給服務器。 論文主要介紹了該系統(tǒng)的整體構架和上位機的實現。上位機的硬件電路的設計主要包括TMS320F2812的最小系統(tǒng)、CAN通信模塊、以太網通信模塊、電子盤存儲模塊等。本系統(tǒng)在TMS320F2812芯片上移植了μC/OS-II實時操作系統(tǒng)，，并在此基礎上實現以太網協議棧、FAT文件系統(tǒng)、CAN通信等各個功能模塊之間的協調工作。
[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.
