多中央协调器场景下用电信息分钟级采集方案设计

Design of Minute Level Power Consumption Information Acquisition Scheme in Multi-CCO Scenario

电力物联网背景下,基于高速电力线载波(high speed power line communication,HPLC)技术的传统数据采集方案无法满足分钟级数据要求,且可能存在多个中央协调器(centralcoordinator,CCO)频段互相干扰等问题,导致现场一次采集成功率不高。因此,文章提出了一种多CCO场景下电表数据分钟级采集方案。该方案首先提出利用网间协调帧机制来保障多个CCO节点协同通信;其次,通过在原有CCO和站点(station,STA)模块的基础上增加数据缓存功能,避免碰撞发生。测试结果表明,与传统用电信息采集方案相比,本设计采集效率提升了约6倍,一次采集成功率达到了100%。

In the background of the power Internet of things,the traditional power consumption information acquisition scheme based on HPLC technology can not meet the requirements of minute level data,and there may be multiple central coordinator(CCO)frequency band interference and other problems,resulting in a low success rate of on-site one-time acquisition.Therefore,a minute level power consumption information acquisition scheme in multi-CCO scenario is designed in this paper.The inter-network coordination frame mechanism was firstly proposed to implement the collaborative communications of multi-CCO nodes.Secondly,the data caching functions were added simultaneously in the CCO and STA modules to avoid collisions.The test results show that compared to the traditional power consumption information acquisition scheme,the proposed scheme can obtain about 6 times efficiency improvement and 100%one-time success rate of acquisition.
