Smart electricity meters typically upload readings a few times a day. Utility providers aim to increase the upload frequency in order to access consumption information in near real time, but the legacy compressors fail to provide sufficient savings on the low-bandwidth, high-cost data connection. We propose a new compression method and data format for DLMS smart meter readings, which is significantly better with frequent uploads and enable reporting every reading in near real time with the same or lower data sizes than the currently available compressors in the DLMS protocol.
翻译：智能电表通常每天上传读数次。 公用事业供应商的目的是增加上载频率,以便近实时获取消费信息,但遗留压缩机未能在低带宽、高成本数据连接方面提供足够的节约。 我们为DLMS智能仪读数提出了一个新的压缩方法和数据格式,通过频繁上传,这比DLMS协议中现有的压缩机的近实时报告数据大小要好得多,并且能够以与目前可用的压缩机相同或更低的数据大小报告每读数。
