Unified History Display Across Volatile and Nonvolatile Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing history management systems in industrial machines display run time monitor screens and execution history screens independently, lacking a user-friendly interface for efficient management of history information.
Innovation Solution
A history management device that simultaneously displays history information from both a high-speed volatile memory and a low-speed, high-capacity nonvolatile memory, allowing centralized management and efficient checking of history information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If history information is stored in separate storage units (volatile memory and nonvolatile memory) and displayed independently, then the system can maintain both fast access and large capacity storage, but the user cannot efficiently manage and check history information centrally
Solution Approach 1:
The patent merges the display of history information from both volatile memory (first storage unit) and nonvolatile memory (second storage unit) into a single unified display interface. The display control unit reads history information from both storage units and presents them together on one screen, allowing users to centrally manage and check all history information without switching between separate screens or interfaces.
2Productivity
If all history information is displayed from one storage unit, then the display system is simple, but the system cannot leverage the advantages of both high-speed volatile memory and high-capacity nonvolatile memory
Solution Approach 1:
The display control unit is designed to perform multiple functions: it can read history information from both volatile memory and nonvolatile memory, manage data from different storage types, and present unified display output. This multi-functional approach allows the system to leverage the high-speed access of volatile memory and the large capacity of nonvolatile memory through a single versatile component.

AI summary
Provided is a history management device for managing history information pertaining to the results of execution of a prescribed process by an industrial machine, the history management device comprising a display unit and a history display control unit that controls the display of history information on the display unit. The history display control unit reads history information from both a first storage unit that stores history information and a second storage unit that stores history information and has a property differing from that of the first storage unit, and the history display control unit simultaneously displays the history information on the display unit.
