The invention relates to a time-frequency
system integrity monitoring method, device and equipment and a storage medium. The method comprises the following steps: acquiring a
time difference measurement result of each time-frequency
signal link and a
temperature measurement result of a time-frequency
system; and inputting the
time difference measurement result and the
temperature measurement result into a
time difference measurement combination
estimation model to generate a temperature change coefficient and a
noise normalization coefficient. And according to the temperature change coefficient and the
temperature measurement result, calculating a temperature removal time difference measurement result to obtain a first time difference measurement result, and according to the first time difference measurement result and a preset sliding window length, constructing a
factor graph model. According to the
factor graph model, time difference forecast deviation and time difference
frequency deviation of each time frequency
signal link are estimated, and according to the time difference forecast deviation, the time difference
frequency deviation, the
noise normalization coefficient and preset integrity monitoring parameters, an RAIM
algorithm is adopted to carry out integrity monitoring on the time frequency
system. By adopting the method, the deviation alarm efficiency and accuracy of the time-frequency system can be improved.
