摘　　要：为保证管道的畅通运行,管道加热装置必不可少,但环境温度变化剧烈,若连续加热自然会增加能耗,降低仪器使用寿命。本文利用CPLD设计了一种管道加热智能测控系统,它可以实现实时监控,具有硬件电路简单,成本低廉,容易升级和复制的优点。In order to guarantee the pipeline＇s unimpeded movement, the heating device of pipeline is essential, but the environmental temperature usually changed sharply, and if the device is heated continuously, it will lead to more energy consumption and reduce the instrumentation life. This passage designed one intelligent measuring and control system of pipeline heating using CPLD, which could achieve the real-time watch and control, have simple circuit of hardware and low cost, upgrade easily and duplicate.

关 键 词：CPLD VHDL 测控 管道加热 能耗
