文档介绍：温湿度测量系统设计(上位机软件设计)
摘要
本课题实现方法是上位机通过RS_485总线及规定的通信协议发出的命令发送给下位机,下位机再根据此命令解释成相应时序信号直接控制传感器。下位机不时读取设备状态数据,转换成数字信号反馈给上位机。上位机对接收到的数据经过处理,在上位机上显示和存储与数据库中等。同时上位机对用户进行管理,方便用户对采集到的数据进行查看及对历史数据的查询等。
介绍了温湿度测量系统上位机的软件构成。用Visual C++作为开发平台,采用MFC类库,,Microsoft Access作为后台开发数据库,m控件完成串口通信设计了一个实时监测上位机软件系统。本文从上位机软件出发,利用面向对象、数据库、串口通信等技术完成系统信息和数据存储、数据和曲线实时显示、历时查询、等功能,实现了上位机系统的监测任务。给出了软件的总体设计方案和各功能模块的设计,说明了该软件的主要功能,并给出了系统的运行界面和应用模式。

Temperature and humidity measurement system design
(PC software design)
ABSTRACT
Approach is PC through RS_485 bus and provisions of munication protocol under orders to send out a machine, lower puter according to mand to explain again into corresponding timing signal directly control sensor. From lower puter equipment state data, converted into digital signal feedback to the PC. PC docking receive data processed, in upper machine display and storage and database medium. Meanwhile PC user management, the convenient user for the collected data in view of historical data and the query etc.
Introduced the temperature and humidity measurement system of software constitutes upper machine. Use Visual C + + as a development platform, using MFC libraries, using dialog-based templates, Microsoft Access as a background, and by using the development of database m control design for plete munication real-time monitoring PC software system. This paper, starting from the PC software by using object-oriented, database, munication plete system information and data storage, data and curve real-time display, lasted inquiry, and other functions, realized the PC system monitoring task. Given the general design of the software solutions and the function module design, shows the software's main function is presented, and the operation of the system interface and application mode.
