【摘要】 输电线路是电力系统的动脉,其运行状态直接决定电力系统的安全和效益。本课题所设计的高压输电线路安全监测系统以预防为主的科学管理思想为基础,在输送电线路发生异常时,及时向管理中心汇报相关数据。该系统对线路杆塔可以进行全天候的监测,能够及时准确的测量由于地面沉降等原因造成的杆塔倾斜角度以及周围的环境气候,当杆塔顺线路或横线路倾斜角度超过预定报警值时,系统可发出报警信息,使工作人员能够及时处理危情,并且大大的减少了人工的巡视次数。GPRS作为新兴的数据传输技术,因其本身具有的覆盖面积广、传输速率快、建设成本低、升级方便等优点而被工业监控领域所关注。论文在分析了GPRS技术的特点和无线监控管理系统的整体设计结构的基础上,把设计的重心放在了终端模块(数据采集模块、GPRS模块)的设计实现上。首先给出了终端模块的设计方案包括硬件的结构和软件的实现并分析了终端模块的功能组成和整体的框架结构图。在硬件方面,选择了微处理器,数据采集模块和通讯模块,在此基础上搭建了硬件工作平台。在软件实现上进行了应用程序的设计。本文从三个部分来介绍高压输电线路安全监测系统的设计与实现:第一部分介绍了高压输电线路安全监测系统的结构、组成等方案设计。第二部分介绍了高压输电线路安全监测系统各单元硬件电路设计原理,其中包括单片机、信号采集、信号处理、信号发送等。其中包括各传感器的硬件设计与使用技巧、数字信号的采集与处理、电源设计、GPRS设计等。第三部分主要介绍了高压输电线路安全监测系统软件设计。论文通过对系统终端软硬件的设计,搭建起了高压输电线路安全监测系统。能够实现服务器和终端模块的联网,以及命令参数等数据的网络传送,从而达到对高压输电线路状态的监测。系统的功能还能进一步进行扩展。总体来说,本论文研究的监测系统具有比较强的实用性和较好的发展前景。更多还原

【Abstract】 Power transmission line system is the artery, decided to direct their operation of the power system security and efficiency .The projects undertaken by the high voltage transmission line design safety monitoring system to prevent the scientific management of the main ideological basis, in the transportation lines anomalies, timely reporting to the management of the data center. The system can be on line tower around-the-clock monitoring, timely and accurate measurement due to ground subsidence and other causes Tower tilt angle climate, as well as the surrounding environment, when the tower with horizontal lines or lines exceeds a predetermined angle alarm level, the system may be issued Alarm information to enable staff to deal with adversity timely intelligence, and greatly reduce the number of inspections.GPRS as a new data transmission technology, because of its wide area of coverage, fast transfer rates, low construction costs, the advantages of upgrading to facilitate monitoring by the industrial areas of concern. In the papers of GPRS wireless technology and the characteristics of the overall monitoring and management system designed on the basis of the structure, focus on the design of the terminal module (data acquisition module, GPRS module) design realization. First is the terminal module design including hardware and software structure and the realization of the functional components terminals module and the overall structure of the framework. In terms of hardware, the choice of microprocessor, data acquisition modules and communication module, based on this hardware platform structures. In the realization of a software application design.In this paper, three parts to introduce high-voltage transmission lines Safety Monitoring System Design and Implementation:The first part of the high voltage transmission line on safety monitoring system structure, composition, such as programme design.The second part of the high voltage transmission line on safety monitoring system hardware circuit design principle modules, including single-chip microcomputer, signal acquisition, signal processing, such as sending signals. Including all sensor hardware design and use of skills, the acquisition and digital signal processing, power supply design, GPRS design.The third part introduces the high-voltage transmission lines safety monitoring system software design.Papers on the system through the terminal hardware and software design, setting up a high voltage transmission line security monitoring systems. It Can be achieved and terminal server networking module, as well as an order parameter data transmission network, so as to achieve the status of high voltage transmission line monitoring. The function of the system could be further extended. Overall, the monitoring system thesis research with a strong practical, and good prospects for development.更多还原
