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.

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: 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. 2. The track tension monitoring method of claim 1, further comprising, when it is determined that the track tension is abnormal, transferring the determination to an output section and externally outputting, by the output section, the determination. 3. The track tension monitoring method of claim 1, wherein, in the abnormality determination mode, when SIP(RIP-1000) orSIP(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 a dynamic state, and RIP is a value obtained by integrating right track tension per unit time in a dynamic state. 4. The track tension monitoring method of claim 1, wherein, in the abnormality determination mode, when 120where N is the number of pieces of data on which determinations have been made, Xi is a measured value of an ith entity, and u is an average of a group. 9. 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; anda 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, and determine, 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. 10. The system of claim 9, wherein the undercarriage module comprises: an idler frame on which an idler is rotatably installed;a main frame configured to be installed on a rear side of the idler and have one or more rollers rotatably installed thereon;a tensioner configured to be installed between the main frame and the idler frame; anda sensor unit configured to be installed in the tensioner and measure tension generated in the tracks by sensing pressure transferred to the tensioner. 11. The system of claim 9, further comprising an output section configured to externally output, when the track tension is determined to be abnormal, the determination. 12. The system of claim 9, wherein, in the abnormality determination mode, when SIP(RIP-1000) orSIP(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 a dynamic state, and RIP is a value obtained by integrating right track tension per unit time in a dynamic state. 13. The system of claim 9, wherein, in the abnormality determination mode, when 120where N is the number of pieces of data on which determinations have been made, Xi is a measured value of an ith entity, and u is an average of a group.
