| 摘要: |
| 传统的专用通道数据传输是通过Modem以点对点的方式实现的。为减少包括数/模、模/数转换在内的各种中间环节,设计了一种数字透传时隙复用设备。该设备由RS-232模块、E1模块和网管模块等组成。通过电平匹配并采用HDB3编码技术和时隙复用技术将RS-232信号转换成标准的E1信号,直接将厂站数据接入数字数据网完成信息传输。该设备在实际应用中有效地提高了通道的稳定性,降低了误码率,方便了厂站自动化设备的调试。 |

| Abstract: |
| Traditional special channel data transmission is realized with point to point mode via Modem. A digital transparent transmission timeslot multiplexer is developed to reduce intermediate ADCs and DACs,which is composed of RS-232 module,E1 module and network management module. It converts RS-232 signal into E1 signal using level matching technology and transmits site data directly via digital data network using HDB3 encoding technology,which improves channel stability,reduces error code rate and simplifies automation equipment commissioning. |
