Frequency Converter Data Retrieval via Wireless Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service personnel face inefficiencies in determining necessary maintenance actions for frequency converters due to the time-consuming process of navigating through user manuals, and existing technologies lack effective methods for streamlined communication of device data for maintenance and service.
Innovation Solution
A method and system for communicating frequency converter data through a wireless communication system, where a local terminal device connects to a frequency converter and transmits identification information to a remote device, allowing retrieval and display of relevant instructional documentation and fault codes, enabling efficient maintenance decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If service personnel manually navigate through user manuals to determine maintenance actions, then comprehensive maintenance information can be obtained, but the process becomes time-consuming and inefficient
Solution Approach 1:
The patent creates a digital copy of maintenance information by transmitting device identification data from the frequency converter to a mobile device, where the corresponding user manual or maintenance information is then displayed. This eliminates the need for physical manual navigation while preserving all maintenance information, resolving the contradiction between information completeness and time efficiency.
2Reliability
If a network apparatus maintains electronic user manuals for frequency converters, then maintenance information is available, but service personnel still face inefficiency in retrieving relevant information
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the frequency converter and the maintenance information stored in the network apparatus. The mobile device receives identification data from the frequency converter, queries the network apparatus for relevant information, and displays it to the service personnel. This intermediary approach maintains reliable information availability while dramatically improving ease of operation by delivering information directly to the user's handheld device.
3Adaptability or versatility
If comprehensive user manuals are provided for frequency converter maintenance, then all possible maintenance scenarios are covered, but the complexity of navigating through the manual increases
Solution Approach 1:
The patent extracts only the relevant maintenance information needed for a specific frequency converter model and transmits it to the mobile device. Instead of requiring service personnel to navigate through comprehensive manuals covering all possible scenarios, the system pulls out and displays only the specific maintenance instructions, fault codes, and operational parameters applicable to the connected device, thereby maintaining adaptability while eliminating navigation complexity.

AI summary
A local terminal device (105) receives (205) from automated power conversion device identification information. The automated power conversion device identification information is forwarded (206) from the local terminal device (105) to a remote device (109) via a communications network. Based on the identification information, the remote device (109) retrieves (207) automated power conversion device instructional documentation from a database. Based on the retrieving, the remote device (109) transmits (208) to the local terminal device (105), at least a part of the instructional documentation via the communications network. The at least a part of the instructional documentation is received (209) in the local terminal device (105) from the remote device (109), wherein the local terminal device (105) detects relevant parts of the received documentation. Based on the detecting, the local terminal device (105) may display (209) the relevant parts of the received documentation.
