基于Modem远程通信技术的在线监测系统

On-line Observation System Based on Modem Long-distance Communication Technology

结合城市污水排放的实际情况,对污水在线监测系统的信息通信及系统管理问题开展了研究,给出了基于调制解调器Modem和公用电话网络的分布式监控系统解决方案。详细论及了Modem在本系统中的使用方法和MSComm控件在modem通信中的应用方法。以Delph i7.0和SQL Server2000数据库作为开发平台,完成程序编写和调试。

Combining the practical situation of city sewage letting, this paper conducts the research of information communication for sewage on -line observation system and the system management, and puts forward the distributivity observation system resolution based on modem and public phone net. This paper also talk in detail about the method of application for Modem in the system, the method of application for MSComm used in modem communication, and how to complete program compiling and debugging using Delphi7.0 and SQI Server2000 database as exploitation plafform.
