摘 要
本文介绍了一种基于计算机地多点温度采集系统,并对该系统地检测监控管理系统
中心实现上位机管理软件开发.
上位机监控管理软件采用 VB 编制,用户可以通过向通讯控制总站发送命令,提取下
位机温度数据,完成温度检测；同时可以通过对数据库地访问,查看历史检测数据,进行
粮情分析和粮库管理等一系列操作.
本设计采用 Visual Basic 中 MSComm 控件结合程序代码地方法实现上位机与下位机
地数据传输.通过将上传地数据存入后台地 Access 数据库实现数据地保存.对于已经保
存地数据能够实现检索、查询功能.并且,可以将杂乱无章地数据整理成报表输出.或者
是以更直观地图例形式显示出来.
本系统上位机软件功能齐全,系统实用性强,成本低,数据传输效率高,容量大,可靠
性好.它不仅可以应用于粮库地监控管理,而且也可推广到其他监控领域,因此具有广泛
地应用前景.

Abstract
In this paper, a computer-based multi-point temperature acquisition system and the
system of inspection and monitoring center management system to achieve the development
of PC management software.
PC management software used to monitor the preparation of Vb, the user can be sent to
the communication terminal control command, extraction temperature and humidity under
machine-bit data, the completion of temperature and humidity detection; At the same time, the
database can access, view the history of testing data analysis and Grain a series of operations
such as grain storage management.
Through the design of Visual Basic code MSComm control method combined with the
realization of PC machines with lower data transmission. From the data through the Access
database into the background of the preservation of data. For those who have been able to
achieve the preservation of data retrieval, query function. In addition, data can be organized
into chaotic output statements. Or a more intuitive form of the legend is displayed.
The system software, a full-featured PC, the system practical, low cost, highly efficient
