【摘要】 在大型集装箱检测系统中,中央控制站需要监测各子系统的运行状态并由此发出动作指令．这些子系统由于其功能各异,有强电、弱电、弱电、高频、低噪声之分,因而对于信号的连接以及干扰的隔离有着不同的要求．本文提出了一种能够满足各种连接与隔离需要的通用数字输入输出模块(DIOM),并详细给出了它的结构与功能．更多还原

【Abstract】 In the Large Container Inspection System,the central control station needs to monitor the peration status of all other subsystems,and to make some actions by sending instructions according to the status.The sub- systems are very different each from other in function,such as high power,very low power,high frequency, low noise,etc.Thus there are various requirements for the interconnection and isolation among the subsys- tems.In this paper,the design of a general purpose digital input/output module(DIOM)is proposed,and the structure and funciton of the module is given in detail.更多还原
