摘要
为了解决传统静态驱动开关阵列模块集成度低的问题,在深入分析静态驱动和动态驱动优缺点的基础上,设计了一种动态驱动的开关阵列模块;简要介绍了VXI总线接口电路的设计方法,重点介绍了模块功能电路的设计,包括动态驱动电路设计、自检电路设计和模块的软件设计;实践应用表明,该模块性能稳定、应用灵活、具有较高的经济实用价值。
For their static-driven circuit,traditional relay matrix modules have disadvantage of low integrated rate.To solve this problem and enhance the utilization rate of module space,a switch module was designed based on dynamic-driven relay matrix.Firstly,the design method on interface circuit of VXI bus was introduced.Secondly and most importantly,the function module circuit was designed,which was composed of dynamic-driven circuit,self-test circuit and the software of module.The engineering practice has verified the stability of the designed module,which also has advantages of flexibility and higher performance-cost rate.
