Classification: CPC B  G | IPC B  G

Claim 7:
8. A system for monitoring tension of a track, the system comprising:
an undercarriage module configured to be installed in a lower part of caterpillar track equipment, to be wound with tracks for travel, and to sense tension of the tracks; and
a controller configured to receive a track tension signal sensed from the undercarriage module, enter, when the tracks are in a dynamic state, an abnormality determination mode for determining whether the tracks are in excessive tension or low tension, measure a track tension under a predetermined condition of the tracks, the predetermined condition includes that the tracks make a turn, the tracks are impacted, or the caterpillar track equipment operates and determine, 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 track tension per unit time in a still state, LIP is a value obtained by integrating left track tension per unit time in the dynamic state, and RIP is a value obtained by integrating right track tension per unit time in the dynamic state.
