【摘要】 随着移动电话技术的发展,手机已经成为人们生活的的一部分。在某种意义上可以说手机重新定义了人们的联系方式、工作的需要以及人与社会的关系。手机的通信畅通离不开移动网络,而移动基站又是移动网络的重要组成部分,是手机联系外界的第一关。只有移动基站正常的运行才能保证移动网络的工作。目前,随着移动网络的需求不断增大,移动基站的规模不断扩大,亟需自动化管理;另外,在偏远的山区等不便于工作人员工作的也需要移动基站的布置,因此,设计一个功能齐全、智能化的移动基站状态远程监测系统有着非常重要的意义。本文设计了一种以GPRS为主要通讯方式的远程数据监视系统。该系统由两部分组成:上位机系统和下位机系统。下位机系统以AT89C51系列单片机为数据采集终端核心,利用GPRS网络将现场采集到的环境数据实时通过无线网络上传至上位机系统,上位机系统通过人机界面直观地展示给用户。上位机系统使用VB语言编写,为用户提供了一个友好的人机交互界面,并与后台SQL Server2000数据库相连,通过曲线实时显示接收到的数据,并自动导入历史数据库以备查询。上位机系统对用户实行分级管理,设定不同的用户操作权限,提高了系统的安全性。这种数据采集终端可以大量分布于监测现场,不需要布线,可随意移动,能够对分散的、无人值守的现场环境数据进行定时采集,并且可以发送简单的控制命令。它克服了传统数据监测系统监测频次低、传输速度慢等问题。本论文对下位机系统、上位机和综合应用进行了测试,经测试运行,本系统的各项技术性能指标已经达到了原设计的要求,成功地实现了小批量、非连续数据的远距离无线传输,为现有的环境监测系统提供了一种便捷的无线数据传输方式,可以代替现有的有线远程监测系统。数据采集终端设备具有很好的通用性,配有多路标准I/O通道,可以同时采集多路环境数据,系统的可扩展性非常强。

【Abstract】 With the increasing of wireless coverage of mobile networks, the construction scale of base stations and the monitoring room is growing. Meanwhile, the job of electricity using information managing in site and environmental monitoring are onerous day by day. It is an irresistible trend that the maintenance and management of base stations and monitoring room will be unattended, centralized, automated. The monitoring system is an important support and tools of maintenance and management of base stations and the monitoring room, and it has became the basic package need in base stations and monitoring room construction. Therefore, the introduction of a new generation,functional and intelligent control system has an important significance.Based on the above considerations, the thesis designs a remote data monitoring system which takes GPRS as the main means of communication. The system takes the AT89C51 Series MCU as the core of data collection terminal, and uses GPRS wireless to upload the collected environmental data to the remote data monitoring centre in real time. The data monitoring centre is prepared by the VB language. It provides a friendly user interface. Though connecting with the background SQL 2000 Server database, it displays the received data by real-time curve, and automatically stores the data into the history database preparing for query. The monitor center realizes the level-to-level administration to the user, establishes the different user operation jurisdiction, enhanced system’s security. This kind of data collection terminal may distribute massively in the monitor scene. It doesn’t need the wiring, but it can move at will, and can gather the environmental data on fixed time. It also can transmit the simple control command. It overcomes low monitor frequency and the low transmission speed of the traditional wired way.The test shows that every parts of the system can meet the requirements of the original design. It makes the remote wireless transmission of small-mass and non-continuous data realized. It offers a convenient wireless data transmission method for present data collecting system, which can take place of the existing cable remote monitoring system. Moreover, the terminal has several standard I/O channels. The system’s scalability is very strong.
