《自动化技术与应用》2023年第42卷第6期计算机与通信技术ComputerandCommunicationTechnologyTechniquesofAutomation&Applications基于电力信息可视化采集的230MHz射频技术研究*梁盈威,杨秋勇,苏华权（广东电网有限责任公司，广东广州510000）摘要:原有的230MHz射频技术在授权用户受到认知用户干扰时，通信过程误码率较高，为此，提出一种基于电力信息可视化采集的230MHz射频技术。设计射频技术中接收灵敏度、动态范围、接收带外抑制等接收发射指标，优化基带对有用信号的调节，消除认知用户的干扰；引入可视化信息采集技术，由230MHz无线专网承担通信工作，设计时序逻辑控制，采用过分配方式定义GTS和CFP的分配，保留通信过程中的处理时间，减小干扰。对比实验结果表明在光谱强度相同时，设计的技术误码率较低，具有有效性。关键词:电力信息；可视化采集；信道干扰；信号生成;射频技术中图分类号：TP391.44文献标识码:A文章编号:1003-7241(2023)06-0127-04Researchon230MHzRFTechnologyBasedonVisualizedPowerInformationAcquisitionLIANGYing-wei,YANGQiu-yong,SUHua-quan(GuangdongGridCo,Guangzhou510000China)Abstract:Theoriginal230MHzradiofrequencytechnologyhasahighbiterrorrateinthecommunicationprocesswhentheauthorizedus-ersareinterferedbycognitiveusers.Therefore,a230MHzradiofrequencytechnologybasedonvisualacquisitionofpowerinfor-mationisproposed.Inordertooptimizetheadjustmentofbasebandtousefulsignalsandeliminatetheinterferenceofcognitiveusers,thereceivingandtransmittingindexessuchasreceivingsensitivity,dynamicrangeandreceivingoutofbandsuppressioninRFtechnologyaredesigned;thevisualinformationacquisitiontechnologyisintroduced,the230MHzwirelessprivatenetworkisresponsibleforthecommunicationwork,thetiminglogiccontrolisdesigned,andtheallocationofGTSandCFPisdefinedbytheoverallocationmethod,soastoretaintheprocessinginthecommunicationprocesstime,reduceinterference.Theexperimen-talresultsshowthatwhenthespectralintensityisthesame,thebiterrorrateofthedesignedtechnologyislow,anditiseffective.Keywords:electricpowerinformation;visualacquisition;channelinterference;signalgeneration;RFtechnology*基金项目：广东电网有限责任公司科技项目（037800KK52190007）收稿...
