AI Technical Summary

Technical Problem

When there are many machines operating, existing technologies cannot properly transmit high-priority information, leading to delayed fault diagnosis or information loss, especially in environments with limited network transmission capacity.

Method used

By installing controllers in the operating machinery, the priority of sending operation information is determined based on factors such as the probability of failure, the importance of the operation, and the availability of alternative machines. Important information is then transmitted preferentially through management servers and repeaters.

Benefits of technology

It enables more reliable transmission of high-priority information even in multi-machine environments, rapid diagnosis of machinery with high failure risk, and improves the accuracy and timeliness of information transmission.

Abstract

Provided are a work machine and a work machine management system that can more appropriately transmit information of a work machine having a high priority even when the number of work machines is large. A work machine (10) has an information controller (20). The information controller (20) acquires operation information of the work machine (10), receives management server information from a management server (90) provided outside the work machine (10), determines a transmission priority order of the operation information based on the content of the operation information and the management server information, and transmits the operation information to the management server (90) or a relay device (80) in accordance with the transmission priority order.
