Unified Data Acquisition Command for Multi-Section Database Queries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data acquisition methods are inefficient when dealing with data spanning multiple definition sections, leading to degraded performance and inflexibility in changing data acquisition definitions.
Innovation Solution
A data acquisition device with an acquisition definition storage unit and a command generation unit that generates a single data acquisition command using query commands and acquisition definition information, allowing data to be acquired from overlapping value definition ranges, thereby maintaining flexibility and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data acquisition commands are transmitted for each definition section, then data spanning multiple definition sections can be acquired, but the processing performance degrades due to the large number of commands required
Solution Approach 1:
The patent combines multiple data acquisition commands for different definition sections into a single unified command. The command generation unit creates one command that includes multiple value designation ranges, each corresponding to a different definition section, thereby acquiring data from multiple sections simultaneously without the performance degradation associated with transmitting separate commands for each section.
2Adaptability or versatility
If data acquisition definition is changed flexibly, then adaptability to sensor updates and time-based corrections is improved, but it becomes difficult to maintain consistency when data is referred to from outside
Solution Approach 1:
The patent performs preliminary actions by storing acquisition definition information that includes value definition ranges and corresponding acquisition methods before data acquisition is needed. When a data acquisition command is received, the system refers to these pre-stored definitions to determine the appropriate acquisition method, ensuring both flexibility in adapting to changes and consistency in data reference through predefined rules.
Solution Approach 2:
The patent introduces an intermediary component (the data acquisition device with command generation unit) that sits between the external data reference and the database. This intermediary uses stored acquisition definition information to mediate the data acquisition process, translating external requests into appropriate database queries while maintaining consistency through the use of predefined value definition ranges and acquisition methods.
3Device complexity
If only one definition section is acquired at a time, then the data acquisition command structure remains simple, but the processing efficiency decreases when acquiring data across multiple sections
Solution Approach 1:
The patent creates a universal data acquisition command structure that can handle multiple definition sections within a single command. The command generation unit generates commands that include multiple value designation ranges, allowing the same command structure to serve both simple single-section acquisitions and complex multi-section acquisitions, thereby maintaining structural simplicity while improving processing efficiency.

AI summary
The present invention is provided with a command acceptance unit (110) to accept a query command (201) to acquire data from a database, the query command including a value designation range to designate a range of a definition value corresponding to the data to be acquired, an acquisition definition storage unit (160) to store acquisition definition information (161) wherein a value definition range is associated with an acquisition method to acquire data from the database, and a command generation unit (120) to judge whether a range that overlaps with the value definition range exists in the value designation range, and when it is judged that the overlapping range exists, to generate a data acquisition command (202) to acquire data corresponding to a definition value included in the overlapping range in an acquisition method corresponding to the value definition range.
