Display Control Device for Simultaneous Multi-Device Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control systems for outdoor information display boards cannot simultaneously compare the display contents of multiple display devices.
Innovation Solution
A display control device that acquires and processes information from multiple display devices, including display device information, preset images, operation states, and positions, to generate a unified display image for monitoring, allowing simultaneous comparison of display contents across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple display devices are arranged to display preset images, then the coverage and information display capability are improved, but the ability to simultaneously compare display contents across devices is lost
Solution Approach 1:
The patent creates a virtual copy of the physical display arrangement in the form of a map image. Each display device's position, displayed content, and operational state are replicated as corresponding elements on the map image, enabling simultaneous visual comparison of all display devices through this virtual representation.
Solution Approach 2:
The patent transitions from viewing display contents on individual physical devices to viewing them on a two-dimensional map image. This dimensional transformation allows all display contents to be simultaneously observed and compared in a single visual field, resolving the limitation of sequential or isolated viewing.
2Area of stationary object
If display devices are distributed across different positions in a facility, then the coverage area is improved, but the complexity of monitoring and managing all devices increases
Solution Approach 1:
The map image serves as an intermediary between the distributed display devices and the observer. It consolidates information from multiple geographically separated devices into a single unified representation, simplifying monitoring and management by providing a centralized overview without requiring physical presence at each device location.
Solution Approach 2:
The map image performs multiple functions simultaneously: it displays the positional information of all display devices, shows the current display content of each device, indicates operational states, and enables comparative analysis. This multi-functionality reduces the need for separate monitoring systems for each function.
3Measurement precision
If display content is monitored on individual devices separately, then the detail of each device's display is preserved, but the ability to perform simultaneous comparison is lost
Solution Approach 1:
The patent merges the display contents from multiple individual display devices onto a single map image while preserving the detail of each device's content. This consolidation allows simultaneous comparison of all display contents in one view, eliminating the time required to switch between or physically move between devices for comparison purposes.

AI summary
A display control device includes: a display device information acquiring unit to acquire display device information indicating each of a plurality of display devices that displays a preset image; a preset image acquiring unit to acquire preset image information indicating a preset image displayed by each of the display devices; an operation state acquiring unit to acquire operation state information indicating an operation state of each of the display devices; a display image generating unit to generate a display image, wherein the display image generating unit generates, for each of the display devices, the display device image in which display device information, a preset image indicated by preset image information, and the operation state information are associated with each other, and generates a display image in which a plurality of generated display device images are aligned.
