摘　　要：电力线通信检测装置是低碳楼宇能源互联网的核心设备,其采用的电力线载波通信(power line communication,PLC)的传输速度虽快,但路径搜索信令的通信可靠性较低,严重制约了中继对通信性能的提升效果;双向工频自动通信系统(two way automatic communication system,TWACS)的可靠性虽然很高,但路径搜索速度较慢,严重影响了通信时效性。为提高电力线通信检测装置在能源互联网信息感知中的性能,提出一种基于PLC与TWACS的多模式融合通信路径搜索算法。为保证电力线通信的覆盖范围,在改进算法中由PLC负责主要数据信息的传输;而下行通信搜索信令则由鲁棒性较强的TWACS替代,以保证广播信息与路径中继指令传输的可靠性。仿真结果表明,所提算法能够有效提高能源互联网的通信质量和通信效率,更好地满足低碳楼宇电力线通信检测装置的性能需求。The power line communication detection device is the core equipment of the energy Internet for low-carbon buildings.Although the transmission speed of power line communication(PLC)used in the device is fast,its path search signaling communication reliability is low,which seriously restricts the improvement effect of the relay means on communication performance.The reliability of two way automatic communication system(TWACS)is high,but its path search speed is slow,which seriously affects the timeliness of communication.To improve the performance of the PLC detection devices applied in energy Internet information perception,an improved path search algorithm of multimodal integration of power line communication using the abovementioned PLC and TWACS is proposed in this paper.In order to ensure the communication coverage,The PLC is mainly responsible for data information transmission,while its downlink communication search signaling is replaced by the strong-robustness TWACS to ensure the reliability of broadcast information and path relay command transmission.The simulation results indicate that the proposed algorithm can effectively improve the communication quality and efficiency of the power distribution network,and meet the performance requirements of power line communication detection devices in low-carbon buildings better.
