Teledata collection system design based on gsm 网的水情数据采集系统设计
It is an new technique of teledata acquisition which is based on service , provided by china telecom , transmitting short messege by fixed telephone network 基于固话短信的远程数据采集是一种新的远程数据采集技术。
After studying and analysing the interrelated knowledge about this new service , in this paper such a new method used for teledata acquisition is introduced and used for realizing the teledata from ammeter administrat system 在对中国电信推出的固话短信业务的相关技术进行了研究和分析后,本文提出基于固话短信的远程数据采集方式并将其用于远程抄表管理系统。
To meet the needs of teledata transit , the digital transmitting techniques are applied to the system , the power line carrier wave tele - circuit with a bus transfer interface is supplied , and what ' s more , a detailed introduction is given to illustrate the operation 为了满足远距离数据传输的需要,将电力线载波数据传输技术应用于冷库温度检测系统中,并设计了带有总线转换接口的电力线载波通信电路,阐述了其工作原理。
Its software functions in receiving and analyzing short message and sending teledata . the later , related to program technique such as multithread communication by serial port com component and so on , is windows application based on sql sever database which is developed in vc + + 6 . 0 environment . it mainly performs som tasks such as sending orders storing and operating teledata and others 抄表管理系统用vc + + 6 . 0编写的基于sqlsever数据库的windows应用程序,涉及串口通信、多线程、 com组件等编程技术,主要完成用户数据的采集、存储和管理任务。
