【摘要】 早期手持设备技术简单、功能单一、缺乏网络通讯功能,然而随着社会的发展,这样的手持设备已经无法满足人们日常生活信息交换的需求,也不能满足工业的需求。随着嵌入式技术的发展,嵌入式CPU的性能大大提高,使得手持设备的功能越来越丰富,不断满足了人们娱乐消费和工业需求。移动互联网是互联网今后的发展趋势,如今越来越多的移动设备集成了通话、短息、社区消息、浏览网页、收发电子邮件和无线上网功能。目前,我国电力需求量越来越多,电力设备和输电线的使用量也急剧增加。输电线和电杆长期暴露在野外的环境中,经常遭遇洪水、地震、狂风、雷击等灾害的损害。这些设施一旦出现事故将会给企业和人民群众造成重大损失。因此,定期巡检输电设备尤为重要。本文研究的巡检系统可以通过串口读取GPS数据以及把现场的场景拍成照片保存到设备上。此外,本文使用了ASP+COM方案实现了远程读取数据,提高了电力部门对设备管理的效率。本论文具体研究内容有以下几个方面：1.介绍Windows CE6.0加载驱动的流程、流驱动的架构和开发方法；使用Visual Studio2005开发Windows CE驱动和应用程序；使用Platform Builder定制内核,选择需要的组件,重新编译下载。2.通过研究串口驱动程序的架构,分析了MDD层与PDD层之间的通信机制和标准流接口驱动程序在分层驱动中的作用；通过多个串口函数,实现了数据接收发送和控制串口硬件的功能。3.使用Visual Studio2005开发平台,设计了Windows CE应用层界面,并解析且显示来自串口的GPS数据。4.为了实现实时读取现场数据,本文采用ASP+COM方案实现远程读取串口数据。深入研究了命令和数据在ASP网页与COM控件,以及COM控件与底层驱动之间相互传输的过程。为COM控件的接口添加了Open、Port、BaudRate、DataBits、StopBits、Parity属性和Close方法。在Open属性的实现函数中调用串口类中OpenPort ()函数打开底层串口驱动程序。从而获取串口GPS数据并判断GPS数据的有效性和解析出经纬度,把这些数据封装成安全数组供网页调用。在Internet网中,任何一台远程客户机(PC机)都可以读取手持设备的串口数据,并以网页形式显示。5.研究了Camera摄像头的驱动原理；在应用程序中实现实时视频监控和抓图功能。更多还原

【Abstract】 The early handheld device is simple technical, single function and being lack of network communication function. With the development of society, the handheld devices have been unable to meet the people’s daily needs of information exchange and the needs of industry. However, with the development of embedded technology and the great improvement of the embedded CPU performance, the function of the handheld device becomes more and more rich which continually meet the people’s entertainment consumption and industrial demands. The Mobile Internet is the trend of the internet in the future. And now, more and more mobile devices integrate many functions such as conversation, messages, community news, webpage browsing, E-mail functionality and accessing to the Internet through wireless networks.At the present time, the demands of electric power in our country increase rapidly as well as the electrical equipments and power lines. Power lines and poles in the wild environment for long-term often encounter the damage to the natural calamities such as flood, earthquake, wild wind,strike of thunderbolt. If these facilities occur accident, they will bring the enterprise and people great loss. Therefore, regular inspection transmission equipment is particularly important.The inspection system researched in this thesis can read GPS data through the serial port and take pictures for the scenes and save them to the equipments. Besides, this paper has used the scheme of ASP+COM to achieve reading data in the long range, which improves efficiency of the equipment management in the Electric Power Departments.This specific research contents in this paper have some following aspects:1. This paper introduces the loading driven process of Windows CE6.0, architecture of the driven and development method of Windows CE6.0. And using Visual Studio2005develop the driver and application of Windows CE. This paper Uses Platform Builder to customize kernel and choose the components you want to recompile and download.2. This paper analyses the communication mechanism between the MDD layer and PDD layer and analyses the effects which the driven program of standard stream interfaces have on a layered driver through the study of architecture of serial port driver. This paper realizes the function of sending and receiving data and controlling the hardware of serial ports by a number of serial port functions.3. This paper using Visual Studio2005development platform designed Windows CE application layer interface, and the GPS data from the serial port is parsed and displayed.4. In order to achieve real-time to read the field data, this article using the scheme of the ASP+COM implemented long-range reading serial port data. This paper made an in-depth study of the transmission of commands and data among ASP page, COM control and the bottom driver. The attributes of Open、Port、BaudRate、DataBits、StopBits、Parity and method of Close were added for COM. In the function of open attribute, this paper calls OpenPort function in serial category in order to open the bottom serial driver program. Hence, we can obtain a serial GPS data and Whereafter, we checked the validity of GPS and parses out its latitude and longitude, which are packaged into a safe array for web calling. In the Internet, any remote client (PC) can read the serial port data of handheld devices and display them in the form of webpage.5. This paper researches the driver principle of Camera. The application achieve the functions of real-time video monitoring and capture image.更多还原
