Abstract
Provided are a system and method for monitoring tension of a track. The track tension monitoring method of determining whether tension of tracks constituting an undercarriage module, which is an undercarriage of caterpillar track equipment, is abnormal includes, when tracks are in a dynamic state, entering an abnormality determination mode for determining whether the tracks are in excessive tension or low tension, and determining, in the abnormality determination mode, whether track tension is abnormal by measuring the track tension when the tracks make a turn, when the tracks are impacted, or when the caterpillar track equipment operates.
Claims15
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.
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.
