基于GSM短消息的远程监控系统的设计与实现
|
摘要
当前,国内在远程监控方面,系统通信的连接方式大多基于有线电缆,在运行过程中会受到使用环境以及距离的限制。而无线通信方式往往受到地形地貌的影响以及频率资源的限制,同时其成本高,维护工作繁重。因此直接利用成熟的第三方网络实现远程监控是监控技术发展的一个新方向。随着移动通信技术的发展,GSM网络已经发展成为十分成熟的无线通信网络,已逐步的应用于监控领域。利用GSM网络作为远程监控系统的信息传输平台是一种有效的方法,其原理简单,安全保密性高,又不需要组建专用网络和维护网络,加上GSM网络覆盖面广,因此与传统的监控系统相比有着其独特的优势。
基于将最新的通信技术融合到传统产业中的考虑,本文综合了计算机、无线数据通信、数据采集、单片机等技术,作者研究与设计了以GSM短消息平台作为数据传输通道,适合监控点移动、分散、无人值守、实时性要求低、具备网络覆盖面大、可不定时动态监控特点的无线数据采集及监控系统。该系统具有用户投资小,运营费用少的优点,并且操作简单。
论文首先介绍了课题研究的背景、发展状况、应用场合、研究的意义等。然后提出了系统的总体设计方案,对数据传输通信协议、数据传输的安全性等内容都进行了一定的设计与研究。接下来简单的介绍了GSM网络体系的特点和短消息的传输原理以及TT50模块的结构功能及相关的AT指令。最后论文重点研究与设计了系统下位机的硬件电路的设计与程序实现,该部分采用C51编程;上位机的程序实现,该部分采用vB编写。
具体来说,本文的工作主要集中在以下几个方面:
1、GSM网络体系的特点及短信息传送原理。
2、TT50透明短信模块的结构特点,并介绍相关的AT指令。
3、上位机PC机与短信模块的通信。PC机通过短信模块实现与下位机远程终端的通信,从而实现监测数据信息的接收与控制命令的发送。
4、如何实现单片机控制短信模块发送和接收短消息。将现场采集到的数据或检测到的开关量的状态以短消息的形式发送到上位机并接收上位机发送来的控制命令,根据不同的命令做出不同的动作,以达到远程监控的目的。
论文研究了如何利用GSM模块结合PC机和单片机系统,将短消息业务与数据采集结合起来,实现远端单片机数据采集、通信,上位机数据接收、发送控制命令等相关技术,并介绍了该技术的应用前景和推广价值。该系统具有一定的通用性,对于远程状态监测、数据传输等的场合具有一定的参考和适用价值。
本文最后,作者对论文所作的研究内容进行了工作总结,同时指出了研究的后续工作和尚且需要解决的关键问题。
Currently,connection type of system communication is mostly based on wire cable,which is easily restricted by working conditions and distance. Wireless connection type of system communication is easily restrictly by topography,requency of natural resources and cost of maintenance and so on. Wireless communication is a new direction of the development of monitor and control and data collection technologies to make use of the ripe third party' s network to realize wireless monitor and control directly.With the development at full speed of mobile communication technology,GSM network has already developed into very ripe wireless communication network,it is gradually used for monitor and control field.It is a very effective method to use GSM network as the information transport platform of wireless monitoring and data collection system,the theory is very simple and has highsecurity,and there is no need to set up special networks and to maintain them,moreover the Area of GSM networks covering is very wide,so this method has many particular advantages over the conventional monitoring system.
The writer synthesizes the technology of computer,wireless data communication and so on,based in the traditional industry,and implements a data transmission channel using GSM short message platform,which can meet the requirement of monitoring and data collection.It is also a monitoring collection system with the features of low investment and low management cost as well.This system has advantages compared with other systems that should meet the requirements as monitoring collection point,and non-strict demand for real-time,remote monitoring.The main points of this paper are as follows.
The paper first discussed the background,developing situation, application occasions and significance of the task and so on.Then,this paper proposed the total design program,which included data transmission agreement and the security of the data transmission and this paper simply discussed the features and structure of GSM network and characteristics of short message service of GSM and the features of TT50 block and AT command of it.At the last,this paper in detail discussed and designed the circuit and program of the terminal system,used C51,the program of the upper-computer,used VB.
The main points of this paper are as follows.
1.The features and structure of GSM network and characteristics of short message service of GSM.
2.The features of TT50 block and AT command of it.
3.Communication between monitor computer and SMS block.Monitor center realizes the spot data collection and monitor commands transmission by communicating with the lower-computer.
4.Single-chip computer controls the SMS block receive or send the short message.This part sends spot data to SMS block of upper-computer,and receives the monitor commands.
The paper researches how to realize the technique of data collection of single-chip computer in the distance,communication,data receiving in the control system,controlling and the interface communication of the computer by the combine of SMS and data transmission between the GSM module and PC, the single-chip computer system and introduces its practical foreground and value,to remote monitor and data collection,it is more interchangeable and it also has the value of the practicality and reference.
At the end of this paper,I has done the work summary for the research of this paper,and pointed out the follow-up work of the design and the key issues to be resolved.
