Patrol Robot Map Event Marker System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile body systems used for patrolling lack the ability to record and display event histories, making it difficult to determine the location of past events and take preventive measures.
Innovation Solution
A mobile body system comprising a mobile body equipped with a camera and a control apparatus that transmits and receives image data and state information, detects events, marks event locations on a map, and stores event information for later review, allowing for the display of event histories and statistical analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If alarm is displayed on the display device, then event notification is provided, but the alarm cannot be checked after erasing and the location of past events cannot be determined
Solution Approach 1:
The system performs preliminary action by automatically recording event location information on the map in advance before any review is needed. When an event occurs, the control apparatus immediately marks the location on the displayed map, so that when users later review event histories, the location information is already prepared and available without requiring additional actions.
Solution Approach 2:
The system creates a visual copy of event location information by displaying markers on the map that represent where events occurred. Instead of storing only abstract event data, the system copies the spatial information onto the visual map display, allowing users to see event locations directly on the map interface without needing to interpret separate data records.
2Loss of information
If the map remains unchanged to show current status, then real-time monitoring is maintained, but the location of past events cannot be identified
Solution Approach 1:
The system uses color changes and visual markers on the map to indicate event locations. Different types of events can be represented by different colored markers or symbols on the map, allowing users to quickly identify where events occurred through visual cues without changing the underlying map structure or requiring complex interactions to locate event positions.
3Area of stationary object
If multiple control apparatuses are used to monitor different areas, then comprehensive coverage is achieved, but coordinating and analyzing event data across systems becomes complex
Solution Approach 1:
The system merges event information from multiple control apparatuses into a unified map display. The map serves as a common visual platform where event markers from different monitoring areas can be displayed together, allowing users to see events from multiple locations on a single interface without needing to coordinate or switch between separate systems.
Solution Approach 2:
The map display system serves multiple functions simultaneously: it shows current mobile body positions, displays historical event locations, and can accommodate data from multiple control apparatuses. This universal platform handles various types of information presentation without requiring separate specialized displays for each function or system.
Data Source
AI summary
A mobile body photographs an image with a camera while moving, and transmits to a control apparatus image data representing the photographed image and state information indicating the state thereof including the location thereof. The control apparatus displays a map including a moving range of the mobile body on a display unit and overlays a route of the mobile body on the map to display the route. The control apparatus detects an occurrence of an event such as finding of an intruder and the location of the mobile body at the time of the occurrence of the event, based on the received image data and state information, and displays a marker indicating the detected location over the map. Whenever an event occurs, an additional marker is displayed over the map and the history of the past events is recorded on the map.
