摘　　要：本文针对传统调制技术使用于电力线通信时质量不稳定等问题,根据扩频技术良好的抗干扰性、抗衰落性将其应用于载波调制,使电力线载波通信应用于煤矿通风监控系统。基于PL2102设计了相关载波发送、接收以及耦合电路的载波模块,采用2MB容量闪存PM25LV016作为存储单元,接口为SPI,配合T/C可完成准确快速的监测监控。通过相关程序设计支持手动修改参数,实现更好的人机交互。In this paper, the traditional modulation technology used in power line communication quality instability and other issues, accord-ing to spread spectrum technology good anti-jamming, anti-fading to its application to the carrier modulation, the power line carrier communi-cation used in coal mine ventilation monitoring system. Based on the PL2102, the carrier module of the related carrier transmission, receptionand coupling circuit is designed. The PM25LV016 memory is used as the storage unit. The interface is SPI, and the T/C can be used to monitorthe monitoring accurately. Through the relevant program design to manually modify the parameters to achieve better human-computer interac-tion.
