力合微(688589.SH)參與制定的國家標準獲批發布
格隆匯10月20日丨力合微(688589.SH)宣佈,近日,國家市場監督管理總局(國家標準化管理委員會)發佈了2021年第12號中國國家標準公吿批准了602項國家標準,公司作為主要起草單位之一制定的國家標準《信息技術 系統間遠程通信和信息交換 應用於城市路燈接入的低壓電力線通信協議》獲得批准發佈。標準編號為GB/T 40779-2021。
GB/T 40779-2021《信息技術 系統間遠程通信和信息交換 應用於城市路燈接入的低壓電力線通信協議》規定了應用於城市智慧路燈接入的電力線通信協議規範,包括物理層、數據鏈路層和應用支持層。本標準適用於所有經由低壓供電線路(220V/380V 電壓等級)供電的智慧路燈應用。
目前我國城市智慧路燈控制沒有統一的電力線通信協議和技術規範,各種技術紛雜,無法互聯互通。以上標準自2022年5月1日起實施,填補了國內城市路燈智能控制電力線通信標準空白,對智慧城市建設和路燈行業智能化並有序發展提供了技術標準支撐,有利於規範化、標準化、規模化發展。
