The monitoring method for fission of a fire-fighting gas cylinder according to claim 9, wherein after the data processing unit receives the real-time pressure data, the real-time temperature data, the real-time strain data and the real-time displacement data in the step 2, the method further comprises the following steps:
step 21: the real-time burst pressure is calculated using the following equation:
P BL =C 1 C 2 ×P LL -formula 1
In the formula 1, P BL Real-time burst pressure; p LL The theoretical burst pressure of the fire-fighting gas cylinder when leaving the factory; c 1 Is a temperature correction coefficient; c 2 Is a strain correction coefficient;
if the real-time temperature data does not exceed the threshold, C 1 =1, if real-time temperature data exceeds a threshold value, C 1 =1.05 to 1.1; if the real-time strain data does not exceed the threshold, C 2 =1, if real-time strain data exceeds threshold, C 2 =1.1~1.2；
Step 22: and judging whether the real-time pressure data exceeds the real-time burst pressure, if so, sending a burst early warning signal to the Internet of things safety online monitoring early warning management system, and sending a burst report by the Internet of things safety online monitoring early warning management system.
