| 摘要: |
| 针对数据通信系统中线路自动控制及灵活转接的需要，设计中采用了模拟开关阵列集成电路的级连，来构成交换矩阵网络。阐述了矩阵交换的基本原理和矩阵交换设备的设计过程，并在试验的基础上给出了数字信号通过矩阵开关时的各项试验数据指标。试验结果表明。信号通过矩阵体时，失真和干扰小，能够较好的满足实际使用要求。控制系统在传送控制信号时使用CRC校验正确率达到99％以上。目前，该设备已成功投入使用。 |

| Abstract: |
| A switching device which can be used in a artificial system was introduced. The basic theory of communicating switching and its process of designing was presented. On the base of testing CRC verified method, the possibility realizing scheme was put forward. This device has been developed successfully and put into application. |
