Solution Overview
Problem
As the scale of IoT systems increases, managing and searching for information from a large number of sensors becomes complex due to the increased volume of data, making it difficult to efficiently retrieve and display relevant information about monitoring targets in real-time.
Innovation Solution
A management server that receives and associates monitoring target information, sensor information, and time information, allowing for efficient storage and retrieval of combined data, which can be displayed to users via an external terminal, enabling easy search and visualization of sensor data, including image data, and generating reports for problem status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of sensors and monitoring devices increases to cover a larger system scale, then the coverage and monitoring capability improve, but the complexity of searching and managing information increases significantly
Solution Approach 1:
The patent segments the large volume of sensor information by associating it with time information, creating time-divided information groups. This allows the management system to handle and search through segmented data portions rather than a single large dataset, reducing the perceived complexity when searching for specific monitoring target information.
Solution Approach 2:
The patent introduces time information as an intermediary element that mediates between sensor information and monitoring target information. By associating sensor data with time stamps and using time information to retrieve and organize data, the system creates an efficient intermediate layer for managing the complexity of large-scale sensor networks.
2Reliability
If all sensor information is stored and managed centrally, then complete monitoring data is available, but the time required to search and retrieve specific information increases
Solution Approach 1:
The patent performs preliminary association of sensor information with time information and monitoring target information during data collection. This pre-organization of data with time stamps and target associations enables rapid retrieval later without requiring complex searches through all stored data, thus reducing retrieval time while maintaining data completeness.
Solution Approach 2:
The patent adds the time dimension to the storage and retrieval mechanism. Instead of storing only sensor data, the system stores sensor information associated with time information, creating a time-based index structure. This dimensional addition enables efficient time-range queries and rapid retrieval of monitoring target information without scanning entire datasets.
3Measurement precision
If sensor information is associated with detailed time information, then the precision of temporal monitoring improves, but the volume of data to be managed increases
Solution Approach 1:
The patent merges sensor information with time information and monitoring target information into integrated data structures. By combining these elements associatively rather than storing them separately, the system achieves precise temporal monitoring without proportionally increasing managed data volume, as the associations create efficient indexes rather than duplicate data.
Data Source
AI summary
A management server, which facilitates search for information, includes storages, a network interface, and a processor. The network interface performs communication with an external device. The processor is configured or programmed to perform a process of associating monitoring target information, sensor information, and time information, with one another to be stored in the storage. Further, the processor is configured or programmed to perform a process of receiving designation information from a host controller, and combining the monitoring target information corresponding to the obtained designation information with the sensor information associated with the monitoring target information to generate combined information and output the combined information to the host controller.
