In recent years, wireless transmission technologies such as NB-IoT (Narrow Band Internet of Things), LoRa (low power consumption local area network wireless standard) and the like are widely used in wireless transmission of data of intelligent meters such as water meters and gas meters. Currently, over 1000 million NB-IoT water meters are applied to vast urban and rural tap water companies, factories, schools, apartments and the like in china.
However, problems are also exposed during the application of NB-IoT water meters. Such as: due to the fact that the power consumption estimation of the NB-IoT communication of the water meters by a water meter company is insufficient, 26500 Li sub-batteries cannot guarantee that the water meters can work for more than 6 years under the condition that a plurality of water meters are uploaded once a day, and even the working years of some water meters are less than 1 year; after the battery low-power early warning, enough time is not reserved for maintenance personnel to replace the battery (the battery is in a power-off stage), so that data transmission fails, and even the water meter with the valve closes the valve due to low power, so that customer complaints are caused.
The reasons for the above problems are mainly:
firstly, the power consumption of NB-IoT communication under weak signals is tens of times of that under strong signals, and most of the data used by many water meter companies to calculate power consumption are obtained from laboratory moderate signals or relatively ideal environments and cannot represent the power consumption under extremely weak signals;
