Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial automated systems, constantly active radio components that send broadcast signals are disruptive and pose security risks due to high density and ease of access, leading to 'RF contamination' and potential incorrect device selection.
Innovation Solution
A method using RFID or NFC tags to establish wireless communication connections between automation components and mobile terminals, where the tag stores requests and information about available connections, allowing the terminal to select and activate specific communication modules only when needed, reducing broadcast signals and enhancing security by requiring a specific read/write device for connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automation components continuously send broadcast signals for wireless connection discovery, then components can be easily discovered and connected, but RF contamination increases and security is compromised
Solution Approach 1:
The patent applies preliminary action by having the mobile terminal read requests from RFID tags on automation components before establishing any wireless communication. The terminal proactively retrieves connection information and authentication data in advance, allowing the automation component to remain in a low-power state without continuously broadcasting, thus eliminating RF contamination while preserving ease of connection.
Solution Approach 2:
The patent introduces an intermediary mechanism using RFID tags as mediators between the mobile terminal and automation components. The tags store connection information and authentication data, enabling the terminal to access automation components without the components needing to continuously transmit broadcast signals, thereby reducing RF contamination while maintaining connectivity.
2Ease of operation
If automation components continuously broadcast wireless connection information, then connection establishment is simplified, but security is compromised due to easy discovery and access
Solution Approach 1:
The mobile terminal performs preliminary action by reading authentication requests from RFID tags before establishing any communication. This advance authentication ensures that only authorized terminals can access automation components, enhancing security while maintaining ease of connection through the automated tag-based authentication process.
Solution Approach 2:
RFID tags serve as secure intermediaries that store authentication data and connection information. The tags enable the mobile terminal to verify the authenticity of automation components without requiring continuous broadcast signals, thus enhancing security while preserving ease of connection establishment.
3Adaptability or versatility
If multiple automation components with communication modules are deployed in high density, then system functionality is enhanced, but broadcast signals become disruptive and difficult to manage
Solution Approach 1:
The mobile terminal reads connection information from RFID tags on automation components in advance, allowing the system to function with high-density components without continuous broadcast signals. The terminal proactively retrieves necessary connection data, enabling multiple components to coexist without signal disruption.
Solution Approach 2:
RFID tags act as intermediaries that store connection information for multiple automation components. This allows high-density deployment of components with communication capabilities while eliminating the need for continuous broadcast signals, as the tags provide connection data on demand through the mobile terminal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces 'RF contamination', enhances security by limiting broadcast signals, and ensures correct device selection in high-density environments, while maintaining compatibility with various radio technologies.
Implementation Method 1
The tag can be an RFID tag or an NFC tag. Such tags are also called transponders, labels, smart tags, smart labels, radio chips or radio labels. The acronym RFID stands for Radio Frequency Identification and refers to a technology which allows automatic identification or radio recognition and localization of the tags.
Implementation Method 2
The acronym NFC stands for Near Field Communication and refers to a wireless communication technology for data connections across short distances and via an electromagnetic near field.
Implementation Method 3
A read/write device provided for this purpose can wirelessly read out data from an RFID tag and store data on the RFID tag. Data is transmitted between transponder and reader by means of electromagnetic waves.
Data Source
AI summary
A method for establishing a wireless communication connection between an automation component and a mobile operating terminal is provided. The automation component reads out a first request from a tag, wherein the operating terminal has stored the first request on the tag using a read/write device, the operating terminal requesting information from the automation component by the first request via wireless communication connections provided by the automation component. The automation component stores the information via the wireless communication connection on the tag and then reads out a second request from the tag, wherein the operating terminal has stored the second request on the tag, the establishment of a first communication connection being requested in the second request. Further, a first communication module of the automation component intended for the first communication connection is activated, the operating terminal then establishing the first communication connection to the automation component.
