复杂可编程逻辑器件在工业CT系统中的应用

Application of CPLD in the industrial CT system

介绍了复杂可编程逻辑器件(CPLD)在大型工业CT系统中的应用,给出了扫描控制系统中的同步触发模块的结构设计与实现,并且给出了设计电路原理图以及仿真结果。工业CT系统的调试过程和实验结果验证:应用在系统的可编程逻辑器件,不但降低了系统和电路的复杂度,同时方便了测试和调试,大大增加了整个系统的灵活性和缩短了实验时间。

In this paper, the application of CPLD in the industrial CT system is discussed. The paper gives an architecture design and the realization of synchronized trig module in the scan control sub system; and also presents the circuit diagram and some result in detail. In the experimental CT system, it is well proved that the application of in system programmable device supplies many advantages: the complexion of system and circuit is reduced; the process of debug and test is very simple; the system is flexible and the testing time is short.
