摘 要：隨著中華人民共和國(guó)工業(yè)和信息化部關(guān)于進(jìn)一步規(guī)范微功率短距離無(wú)線電發(fā)射事項(xiàng)進(jìn)的公告，通過技術(shù)指標(biāo)來(lái)規(guī)定民用計(jì)量?jī)x表的使用場(chǎng)景。尤其是“單次發(fā)射持續(xù)時(shí)間：不超過 1 秒”使 LoRa 技術(shù)在民用計(jì)量?jī)x表的 使用受到限制。為找到一種能符合要求的將 LoRa 技術(shù)應(yīng)用到民用計(jì)量?jī)x表的方案，通過對(duì) LoRa 技術(shù)的深入分析和大量實(shí)驗(yàn)驗(yàn)證，提出無(wú)線網(wǎng)關(guān)覆蓋呼叫無(wú)線網(wǎng)絡(luò)節(jié)點(diǎn)的方法。

Abstract: With the announcement of the Ministry of Industry and Information Technology, PRC on the further regulation of micro-power short-range radio transmission matters, the use scenarios of civil measuring instruments are stipulated through technical indicators. In particular, the "single launch duration: no more than 1 second" limits the use of LoRa technology in civil measuring instrument. In order to find a scheme that can meet the requirements of applying LoRa technology to civil measuring instrument, through the in-depth analysis of LoRa technology and a lot of experimental verification,a method of wireless gateway repeated call wireless network nodes is proposed.
