摘　　要：设计一种以STC12C4052AD单片机为核心的温度报警系统。利用LabVIEW的用户事件技术实现了对温度的报警,显示报警记录。通过XT8811芯片的USB转串口的功能实现只用一条USB线就可以进行ISP在线编程和传输数据。该系统很方便地完成数据采集及报警等功能,可广泛应于测控领域。A temperature--alarm system taking STC12C4052AD single chip as the core has been designed. By using the technology with user event of LabVIEW, temperature-alarm and alarm records play are realized. One USB wire might carry on the ISP online programming and the data transmission through the USB-com function of XT8811 chips. The system is very easy to complete data collection and alarm functions, and it should be widely applied in the measurement and control domain.
