基于通用MODEM区域水文资料遥测系统设计

The Design of the Hydrologic Observation System Based on PSTN

介绍一种简单的区域水位、雨量遥测系统。系统由 PIC1 6 C73单片机、普通调制解调器及工业级 PC机构成。 PC机能通过共用电话网实时和定时查询各水文站点的水文数据 ,为水文预报提供依据。

Based on PSTN,a hydrological observation system,which consists of MCUs, MODEMs and a industrial PC,was studied in this paper.Using this system,hydrological information,such as water depth and precipitation,can be collected automatically and regularly.
