1. A track tension monitoring method for determining whether tension of a track constituting an undercarriage module, which is an undercarriage of caterpillar track equipment, is abnormal, the method comprising:
obtaining SIP when tracks are in a still state;
entering an abnormality determination mode for determining whether the tracks are in excessive tension or low tension when the tracks are in a dynamic state;
measuring a track tension under a predetermined condition of the tracks, wherein the predetermined condition includes that the tracks make a turn, the tracks are impacted, or the caterpillar track equipment operates;
and
determining, whether track tension is abnormal based on the measured track tension,
wherein, in the abnormality determination mode, when
SIP<(LIP−1000) and SIP>(RIP−1000) or
SIP<(RIP−1000) and SIP>(LIP−1000),
it is determined that there is rotational abnormality,
where SIP is a value obtained by integrating a track tension per unit time in the still state, LIP is a value obtained by integrating a left track tension per unit time in the dynamic state, and RIP is a value obtained by integrating a right track tension per unit time in the dynamic state.
