摘　　要： 虚拟仪器将计算机检测技术与控制技术紧密融合，在进行环境参数测量时无需使用大量的测量设备，极大的降低了开发成本。本文设计了一种基于LabVIEW与STC89C54RD＋单片机的智能温度数据采集系统。下位机将采集到的温度信号通过PL2303HX芯片的RS232转USB接口的双向功能，实现了只用一条USB线就可以把数据信号传输到上位机中进行显示和存储。系统运行结果表明，该测量系统具有测量精度高，设计简单，易于维护，可视性好等优点。 The virtual instrument integrates closely the computer detection technology and the control technology. With the virtual instrument, environmental parameters are measured without a large number of measuring equipment and the development cost is greatly reduced. This paper describes the design of a data acquisition system of intelligent temperature controller based on STC89C54RD ＋ and LabVIEW. Slave computers will transfer the temperature signals collected by the PL2303HX chip RS232 to USB interface with bidirectional function ,which makes it possible to transmit the data signals to host computers for display and storage with only one USB line. The running results show that the measuring system is precise in measurement, simple in design, easy to maintain and good in vision.
