Work Machine Communication Carrier Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Management systems for work machines face difficulties in identifying abnormal mobile communications carriers when transmitting information to a management device, as they struggle to determine which carrier is experiencing issues despite recognizing missing or defective information.
Innovation Solution
A communication management system that includes a work machine with a communications carrier setting unit, a communication unit, and a communication state analyzing unit to gather and analyze communications carrier information over time, determining abnormalities based on changes in data transmission numbers or rates, and associating this information with positional data for display on a map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile communication is used to transmit work machine information to a management device, then communication coverage and flexibility are improved, but the ability to identify abnormal communications carriers deteriorates
Solution Approach 1:
The work machine preliminarily records the communications carrier information before transmission occurs. This allows the management device to have reference data available when analyzing transmission status, enabling identification of which carrier should have been used versus which carrier actually received the information.
Solution Approach 2:
The system implements feedback by having the work machine transmit not only work information but also communications carrier information back to the management device. The management device then analyzes this feedback data along with transmission status to determine whether abnormalities occurred in specific carriers.
2Reliability
If the management device monitors communication status to detect abnormalities, then communication reliability is improved, but the complexity of the system increases
Solution Approach 1:
The work machine autonomously generates and transmits the communications carrier information without requiring additional monitoring equipment. The machine essentially monitors and reports its own communication status, reducing the need for complex external monitoring systems.
Solution Approach 2:
The communication device in the work machine serves multiple functions: it not only transmits work information but also records and transmits communications carrier information. This multi-functionality eliminates the need for separate monitoring devices, reducing overall system complexity.

AI summary
A communication management system in which a work machine communicates with an outside of the work machine, the communication management system includes: a work machine including: a communications carrier setting unit configured to set a communications carrier that provides a communication service to generate information about the set communications carrier as communications carrier information; and a communication unit configured to transmit the communications carrier information to the outside of the work machine; and a communication state analyzing unit configured to gather statistics on the communications carrier information included at two or more different times among pieces of the communications carrier information transmitted from the communication unit, the statistics gathering being performed for each of the times.
