Drive Server Module Integrating Web Communication for Motor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drive systems for motor control face limitations in accessibility, communication speed, and compatibility, often requiring proprietary hardware and software, intermediary components, and restricted communication protocols, which hinder efficient interaction and coordination with drives in industrial environments.
Innovation Solution
A drive system with a directly integrated server module that communicates directly with the drive module via a shared processing unit, allowing for seamless data transmission and access through standard internet protocols, eliminating the need for specialized hardware and software at user locations and enabling coordinated updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If proprietary hardware and software are used for drive control, then drive functionality is achieved, but accessibility and compatibility are reduced
Solution Approach 1:
The drive controller is designed to function both as a traditional drive controller and as a web server, allowing it to communicate through standard web protocols while maintaining its motor control capabilities. This multi-functionality eliminates the need for separate proprietary communication hardware.
Solution Approach 2:
A web server interface acts as an intermediary between the drive controller and standard computing devices, translating between industrial control protocols and standard web protocols. This mediator enables compatibility without requiring changes to the core drive functionality.
2Speed
If intermediary devices are used for communication, then drive control is achieved, but communication speed is reduced
Solution Approach 1:
The web server functionality is merged directly into the drive controller's processing unit, eliminating separate intermediary communication devices. This integration allows direct communication between the drive and standard computing devices through the network, reducing communication latency.
Solution Approach 2:
The communication intermediary function is extracted from separate hardware and embedded within the drive controller itself. This consolidation removes the need for additional communication hardware while maintaining the ability to interface with standard networks.
3Ease of operation
If specialized control terminals are used, then drive accessibility is achieved, but ease of operation is reduced
Solution Approach 1:
The drive controller provides both traditional drive control functions and web server capabilities, enabling access through any standard web browser. This universality allows operators to use common computing devices instead of specialized terminals.
Solution Approach 2:
Specialized control terminals are replaced with standard computing devices that use web browsers. The mechanical and hardware-specific interface is substituted with a software-based web interface that runs on conventional computers, tablets, or smartphones.
4Adaptability or versatility
If proprietary software is used, then drive control functionality is achieved, but adaptability is reduced
Solution Approach 1:
A web server software layer acts as an intermediary between the proprietary drive control system and standard web protocols. This software mediator translates proprietary commands into standard web requests and responses, enabling compatibility with any web-capable device.
Solution Approach 2:
The communication interface parameters are changed from proprietary protocols to standard web protocols (HTTP, TCP/IP). This parameter change allows the drive to communicate using universally supported protocols while maintaining internal proprietary control mechanisms.

AI summary
The present invention relates to a drive system that includes a module that operates as a server, where at least sometimes the module is at least one of directly integrated with another module that operates as a drive and fully integrated to include the drive. The server allows for communications with one or more terminals via an internet-type communications medium, while the drive is for controlling, monitoring and/or otherwise interacting with at least one motor, electromechanical machine, or other appropriate type of machine/process. In at least some embodiments, the server is capable of providing web pages, executable programs and/or other information including, for example, information in accordance with an FTP protocol onto the internet for receipt by the terminals. The terminals communicate commands and other information via the internet back to the server, which in turn can influence the drive and the controlled machine/process.
