The identification characters used for identifying different information contents in the calendar alarm information are multiple, and the multiple identification characters are in one-to-one correspondence with the different information contents.
The label value corresponding to the label is specifically the information content in the alarm information corresponding to the identification character.
For example:
the NAM is Absormal _ Body _ Temperature _ Alert, wherein the NAM is a label, Absormal _ Body _ Temperature _ Alert is a label value, and the information represents that the time name of the current alarm information is Absormal _ Body _ Temperature _ Alert;
