further, the air pressure variation data includes: rate of change of air pressure and amount of change of air pressure.
Further, step 103 specifically includes:
step 1031, comparing the air pressure change data with a preset early warning threshold, and if the air pressure change rate is greater than the first early warning threshold and the air pressure change amount is negative, sending out a liquid leakage warning message;
