摘 要：随着中华人民共和国工业和信息化部关于进一步规范微功率短距离无线电发射事项进的公告，通过技术指标来规定民用计量仪表的使用场景。尤其是“单次发射持续时间：不超过 1 秒”使 LoRa 技术在民用计量仪表的 使用受到限制。为找到一种能符合要求的将 LoRa 技术应用到民用计量仪表的方案，通过对 LoRa 技术的深入分析和大量实验验证，提出无线网关覆盖呼叫无线网络节点的方法。

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.
