建筑外窗保温性能检测装置测控系统的设计与实现

以建筑节能为目的，介绍了一种建筑外窗保温性能检测装置测控系统的设计与实现。依照现场总线的技术要求，系统硬件采用通用微型计算机为主机，各种测控仪表为从机，双绞线为传输介质，按照RS-232／RS-485串行总线标准及接口技术实现主从机之间的信息交换。讨论了在Visual C＋＋开发平台下，利用串口类CSerialPort实现多串口通信，以及多线程、数据库、打印等功能的实现。实现了根据国家标准GB／T8484-2002的要求完成的测控功能。

Design and Implementation of Test and Control System for Thermal Insulating Properties of Windows

For the purpose building energy saving, this paper introduces the design and implementation of test and control system for thermal insulating properties of windows. In accordance with the requirements of field-bus technology, the system uses a microcomputer as its master computer, the measurement and control instruments as its slave computers, and twisted-pair line as its transmission medium. In addition, it realizes information exchange between the master and slave computers according to the RS-232/RS-485 serial bus standard and the interface technology. The paper also discusses how to implement, on the Visual C＋＋ developing platform , multiple serial port communication using the serial class named as CSerialPort, as well as such functions as multi-threading, database and printing. The system realized test and control functions as required by the national standard of GB/T 8484-2002.
