介绍了基于可编程序控制器的核供热堆控制棒逻辑控制系统模型。详细地介绍了核供热堆棒控制系统的功能及实现方法。通过对该系统的整体结构的分析，在易于扩展的前提下，对控制棒选择中的互锁算法进行了讨论，并进一步探讨了在可编程序控制器的开发过程中的时序问题。
The logic control system model of nuclear heating reactor control rod based on programmable logic controller is introduced. The function and the realization method of nuclear heating reactor control system are introduced in detail. Through the analysis of the overall structure of the system, under the premise of being easy to expand, the interlocking algorithm in control rod selection is discussed, and the timing problem in the development of programmable logic controller is further discussed.
