【摘要】 由单片机构成的数据采集系统和PC机通过串行口构成的微机系统已经广泛应用于工业控制、水文测量、气象测量和环境监测等领域,这些系统大多采用RS-232,RS-485或是有线MODEM的通信方式,虽然经济实用,但其有线数据传输方式在很大程度上限制了应用场合的拓展。无线远程监控是监控技术发展的一个重要方面。直接利用成熟的第三方网络实现无线远程监控是远程监控发展的一个新的方向。随着移动通讯技术的飞速发展,利用现有的GSM网络资源,发挥网络覆盖率高、传输特性好等优势,为现有数据采集系统提供一种便捷的无线数据传输方式,这必将成为工业控制及现场监测等领域的发展趋势。在一些小数据量传输的监控场合,人们可以直接利用GSM网路中的短消息业务(SMS)进行数据传输实现无线远程监控。采用短消息业务进行数据传输和普通的无线数据传输方式相比,具有许多明显的优点:数据传输可靠;费用低廉;传输距离远,在GSM网络覆盖的区域基本不受地域的限制等等。本文介绍了一种基于GSM网络短消息(SMS)的远程监控终端的设计与实现。该监控终端是针对小型用户设计的,具有一定的通用性。对于不同的监控对象用户只需对监控终端进行不同的定义。另外,本监控终端采用的是中文短消息的方式进行操作,使用更加方便。这些都是本监控终端突出的特点。本监控终端主要由两部分构成:GSM引擎模块和以单片机为核心的监控单元。GSM引擎模块采用的是西门子公司生产的MC35I模块,它主要用来收发短消息,监控单元则用来完成具体的监控任务和PC机及TC35T进行通讯。本文主要包括以下几个部分:第一部分为绪论。介绍了本课题的研究目的和意义以及完成的主要工作和本系统的主要功能:第二部分介绍了GSM短消息(SMS)的相关知识;第三部分介绍了短消息收发模块MC35I以及AT指令的相关内容;第四部分介绍了监控终端的功能模块的硬件设计;第五部分介绍了本系统的软件设计流程。第六部分结论与展望。更多还原

【Abstract】 Data collecting system composed of MSC and micro-computer system composed of PC in series have already been widely used in industrial control,meteorological phenomena measurement and environmental monitoring etc.These systems mostly apply RS-232,RS-485 or cable modem,though very economical and practical,but cable data transmission has limited its application prospects to a large extent.Wireless remote monitor and control is an important respect of the development of automatic technology.It is a new direction of the development of monitor and control technologies to make use of the ripe third party’s network to realize wireless remote monitor and control directly.With the development at full speed of mobile communication technology,By using existing GSM network resources,taking the advantage of wide covering,good transmitting characteristics,a convenient wireless data transmission method has been put forward for present data collecting system. This shows the trend in the field of industrial control and live monitoring.In the case of monitor and control field transmitting a little amount of data amount,People can utilize short message service(SMS)in GSM networking directly to transmit data in order to realize wirelessly remote monitoring and controlling.Compare with ordinary wireless data transmission means,adopting the short message service to transmit data have a lot of obvious advantages:data transmission is reliable;the expenses are cheap;the transmitting distance is very far with little restricted by region basically in the area covered by GSM networking etc.This paper has introduced the design and application of a kind of wireless remote monitor and control terminal based on the short message service(SMS)of GSM network.The terminal is designed for small-scale user,and has certain commonability.User only needs to self-define the terminal differently according to the different objects monitored and controlled.In addition,the terminal is operated by the means of Chinese short message,and it is more convenient to use.All these are the outstanding characteristic of the terminal.The terminal consists of two parts mainly:GSM engine module and a monitor and control unit taking single-chip computer as the core.The GSM engine module is the MC35I module produced by Siemens Company;it is used for receiving and delivering short message mainly.The unit is used to finish the concrete monitor and control task,and communicate with PC or MC35I.This paper includes the several following part mainly:The first part is the foreword.It has introduced the study purpose and significance of the topic,the work that has been done and the leading function of the terminal.The second part has introduced the relevant knowledge of the GSM short message service(SMS).The third part has briefly introduced GSM engine module TC35T and the relevant knowledge of AT commands.The fourth part has introduced the hardware design of the function modules.The fifth part has introduced the process of the software design.The sixth part is conclusion and prospect.更多还原
