【摘要】：油罐运输车是一种常用的石油制品运输工具。由于油罐车在运输途中监管不力，油品的人为损失严重，给石油公司带来了巨大的经济损失。如何加强油罐车运输的监管，已经成了石油公司亟待解决的问题。针对传统的油罐车监管方法成本高、精度低和实时性差等缺点，本论文提出了一套油罐车远程监控系统的设计方案。该系统由两部分组成，分别是远程控制中心和车载设备。本论文主要针对车载设备中的车载主控单元进行了设计。本论文主要针对车载主控单元的总体系统、硬件电路、软件流程和机构进行了设计，并对最终的系统进行了测试验证。在系统总体设计部分，对油罐车远程监控系统的组成，车载主控单元与系统各部分的连接关系做了说明，探讨了主控单元的整体硬件设计和软件状态机模型。在硬件设计部分，首先对车载主控单元的整体硬件做了详细规划，，选用ST公司的STM32F103VB作为主控芯片。并分别对远程通信模块、驱动单元通信模块、人机接口模块、GPS定位模块、倾角检测模块、信息存储模块和电源模块进行了设计，探讨了各模块的器件选型。在软件设计部分，对主控单元进行软件功能需求分析，设计了基于嵌入式操作系统μC/OS-II的应用层软件。本文将主控单元的应用层软件划分为4个任务，分析了每个任务的功能和各任务之间的关系。在系统测试部分，阐述了车载主控单元软件的黑盒测试、白盒测试原理和步骤，并对车载主控单元进行了模拟测试，验证了其有效性和可靠性。论文最后对车载主控单元的设计进行了总结，指出了设计中的不足之处，并通过分析给出了改进方案。
[Abstract]:Tank truck is a commonly used vehicle for transporting petroleum products. Because of the poor supervision of oil tanker during transportation, the artificial loss of oil product is serious. Oil companies have brought huge economic losses. How to strengthen the regulation of tanker transportation has become an urgent problem for oil companies. Because of the shortcomings of low precision and poor real time, this paper puts forward a design scheme of remote monitoring system for oil tanker. The system is composed of two parts. This paper mainly focuses on the design of the vehicle main control unit in the vehicle equipment. In this paper, the overall system, hardware circuit, software flow and mechanism of the main control unit are designed, and the final system is tested and verified. In the part of the overall design of the system, the composition of the remote monitoring system and the connection between the main control unit and each part of the system are explained. The overall hardware design and software state machine model of the main control unit are discussed. In the part of hardware design, the whole hardware of the vehicle main control unit is planned in detail, and the STM32F103VB of St company is selected as the main control chip. The driving unit communication module, man-machine interface module, GPS positioning module, inclination detection module, information storage module and power supply module are designed, and the device selection of each module is discussed. In the part of software design, the software functional requirements of the main control unit are analyzed. The application layer software based on embedded operating system 渭 C / OS-II is designed. In this paper, the application layer software of the main control unit is divided into four tasks, and the relationship between each task and the function of each task is analyzed. In the part of system testing, the black box test, the white box test principle and the steps of the on-board master control unit software are described. The simulation test of the vehicle main control unit is carried out to verify its validity and reliability. Finally, the paper summarizes the design of the main control unit, points out the shortcomings of the design, and gives the improvement scheme through analysis.
