The invention belongs to the technical field of alarm monitoring, and discloses a fire-fighting equipment power supply monitoring alarm method and
system, and the method comprises the following steps: obtaining an amplitude characteristic to generate a
voltage reference, recognizing a difference amplitude direction to judge
voltage abnormity, analyzing a
phase change to prompt current abnormity, comparing
temperature and pressure data to generate a combined alarm, and evaluating a link state to generate an uploading instruction. Multi-
source data collaborative monitoring and abnormal response are completed; through
continuous analysis of amplitude fluctuation, difference amplitude direction and
phase change, a multi-parameter linkage trend identification mechanism is constructed,
cross validation of measurement data is realized by combining bidirectional deviation comparison of pressure and temperature, a link
packet loss rate and a
delay monitoring result are fused to establish a communication state evaluation channel, an upload
path switching instruction is dynamically generated, and a communication state is evaluated. The
data transmission stability and response efficiency in an abnormal state are improved, early warning, type identification and linkage
processing of electrical
abnormality in a complex working condition are realized, and the sensing capability and the adaptive
processing level of the
system are enhanced.
