【摘要】：当前,通信技术、电子信息技术和工业控制技术飞速发展。为了能在大型工程机械作业的危险复杂环境中,更大限度地保护现场人员的人身安全,越来越多的无线远程遥控设备出现在生产一线。但与此同时工业设备维护和故障诊断正面临越来越多的挑战,有必要对它们的实时状态有详细的掌握,以便及时发现问题,帮助制定运营维护方案。本论文依托基于Mesh网络的车辆智能监测系统,设计并实现了手持监测单元,具备良好的HMI人机界面,能够在矿下基站信号无法覆盖的地方,对车辆进行实时状态信息监测、机车历史记录采集、紧急情况控制机车和重要控制量的配置和下发等任务。解决了在井下信号盲区无法进行车辆状态监测的问题。手持监测单元使用LPC1768核心控制芯片。用户根据屏幕上的菜单页面选择所要执行的任务,任务指令按通信协议组包后,C02128通信芯片将数据透明传输给目标设备。手持监测单元收到回复后将数据提取出来显示在液晶屏指定位置,完成设计的信息采集和通信控制任务。同时,手持监测单元具备离线数据导入功能,可将采集到的机车数据通过RS-232接口导入上位机监测软件。本文首先简介课题研究背景、国内外研究现状及预期研究目标;其次详细阐述了基于Mesh网络的车辆智能监测系统整体架构和各部分主要功能,并对无线Mesh网络和Ad-Hoc网络进行简介;接着从整个系统的硬件出发,研究Flash、EEprom存储、电源、按键开关机、RS232接口等电路设计;随后对软件平台用到的数据存储、菜单结构、任务事件管理、透传通信模式和整体流程等模块进行设计;再根据手持监测单元各个功能要求,分别设计通信协议、HMI人机界面和上层功能的软件处理逻辑;最后对整个子系统进行测试和结果分析。实际测试结果表明HMI人机界面设计整洁合理、页面切换运行流畅,结合通信协议实现了信息采集、指令下发、数据上传的功能,达到预期设计目标。
[Abstract]:At present, communication technology, electronic information technology and industrial control technology are developing rapidly. In order to protect the people's personal safety in the dangerous and complex environment of large engineering machinery operation, more and more wireless remote control devices appear in the production line. But at the same time, the maintenance of industrial equipment and the positive fault diagnosis are positive. In the face of more and more challenges, it is necessary to have a detailed grasp of their real time status so as to find out the problems in time and help to establish the operation and maintenance scheme. Based on the vehicle intelligent monitoring system based on Mesh network, this paper designs and implements a handheld monitoring unit, with a good HMI man-machine interface, and can not cover the signal of the base station under the mine. In the area, the vehicle carries on the real-time state information monitoring, the locomotive history record collection, the emergency control locomotive and the important control quantity configuration and the sending and other tasks. It solves the problem that the vehicle state monitoring can not be carried out in the underground signal blind area. The handheld monitoring unit uses the LPC1768 core control chip. The user is based on the menu page on the screen. The task instruction is to be performed by the communication protocol group. The C02128 communication chip transmits the data transparently to the target device. After receiving the reply, the handheld monitoring unit is extracted and displayed on the specified location of the LCD screen to complete the design of information acquisition and communication control tasks. Meanwhile, the handheld monitoring unit has the off-line number. According to the import function, the collected locomotive data can be imported into the upper computer monitoring software through the RS-232 interface. This paper first introduces the research background, the domestic and foreign research status and the expected research goals. Secondly, the whole architecture and the main functions of the vehicle intelligent monitoring system based on Mesh network are described in detail, and the wireless Mesh network and A are also introduced. D-Hoc network is introduced, and then from the hardware of the whole system, the design of Flash, EEprom storage, power supply, key switch machine and RS232 interface are designed, and then the modules of data storage, menu structure, task event management, transmission and communication mode and whole process are designed for the software platform; and then according to the handheld monitoring unit Function requirements, design communication protocol, HMI human-computer interface and upper function software processing logic respectively. Finally, the whole subsystem is tested and result analysis. The actual test results show that the HMI man-machine interface design is clean and reasonable, the page switch runs fluently, and the functions of information collection, instruction, and data upload are realized with the communication protocol. To achieve the desired design goals.
