Specifically, the NB-IoT water meter daily freezing data reporting method comprises the following steps:
and S1, acquiring and storing daily frozen data, and recording the number of days of the frozen data. Specifically, the NB-IoT water meter acquires data to be counted every day, and stores the data to be counted as daily freezing data into a storage unit of the NB-IoT water meter. Optionally, the NB-IoT water meter acquires data to be counted at a preset time point every day, and stores the data to be counted as daily freezing data into a storage unit of the NB-IoT water meter. And the NB-IoT water meter records the number of days of frozen data after the day frozen data is stored, and the number of days of frozen data is increased by one day when the day frozen data is stored once.
And S2, if the number of days for freezing the data reaches a preset number of days, uploading all day freezing data to a server, wherein the preset number of days is at least two days. Specifically, the NB-IoT water meter judges whether the number of days of frozen data reaches a preset number of days after the number of days of frozen data is updated every time, if the number of days of frozen data does not reach the preset number of days, daily frozen data of each day is continuously acquired and stored, and meanwhile, the number of days of updating frozen data is recorded; and if the number of days for freezing the data reaches the preset number of days, reading all the day freezing data which are stored in the storage unit and are not uploaded, and uploading all the day freezing data to the server. The preset number of days is set by the user, and the preset number of days is at least two days, for example, 7 days, 10 days, 30 days, etc. can be selected. It can be understood that the data volume of the daily frozen data is small, and even if the daily frozen data is accumulated for multiple days, the daily frozen data does not occupy more storage space, and the uploading time at one time is not obviously prolonged. That is to say, the daily frozen data accumulated for multiple days does not consume excessive power when being uploaded once, and the number of times of starting the NB-IoT communication module can be reduced by times when the data is uploaded once every multiple days, so that the power consumption of the NB-IoT communication module is reduced by times. Considering that the NB-IoT communication module is an important power consumption module of the NB-IoT water meter, the service life of the battery can be prolonged by times after the electric quantity of the NB-IoT communication module is reduced by times, so that the battery replacement times are reduced, and the management and maintenance cost is reduced.
