摘要：Problem to be solved: to provide an abnormality management system of a

construction machine capable of giving priority to a plurality of alarms. The management

unit 23 receives signals from the communication terminals 11 of the hydraulic excavators

1a-1c to manage the states of the plurality of hydraulic excavators ment

deviceA receiver 25 receiving abnormal information transmitted from a plurality of

hydraulic excavators 1a-1c andAn analysis section 27, which analyzes whether the

occurrence rate of abnormal information of each of the hydraulic excavators 1a-1c within

a predetermined period TA is higher than the average incidence rate Pb calculated from

the sum of the abnormal information transmitted from the plurality of hydraulic

excavators 1a-1c, isA notice changing section 28 for changing the level of the notification

mode of abnormal information of the hydraulic excavators 1a-1c, which has a higher

occurrence rate PA than the average incidence Pb, andA transmission section 26 for

transmitting the notification mode changed by the notification change section 28 is
