Wireless Field Device Broadcast for Fast Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for integrating multiple field devices into wireless networks are time-consuming and require existing network participants, limiting the ability to set up networks from scratch or transmit information without prior integration.
Innovation Solution
A method for wireless transmission of information between an initiator and multiple receivers involves sending a command-containing communication pulse, with recipients switching to confirmation mode and retransmitting, allowing exponential, undirected propagation without needing prior network integration, using a dedicated radio channel and adjustable transmission power.

Engineering Contradiction Analysis
1Measurement precision
If each field device is configured separately using cable connection and PC-based configuration programs, then network settings can be transferred to individual field devices, but the configuration process becomes extremely time-consuming
Solution Approach 1:
The patent merges the configuration process for multiple field devices into a single wireless operation. Instead of connecting each device individually via cable, the system transmits configuration data wirelessly to multiple receivers simultaneously, combining what was previously separate manual operations into one automated process.
Solution Approach 2:
The patent replaces the mechanical cable connection system with a wireless transmission system. Physical cable connections and manual PC-based configuration are substituted by wireless communication protocols that automatically transmit configuration data to field devices without physical intervention.
2Ease of manufacture
If existing network participants are required for integration methods, then network settings can be determined and transmitted, but it becomes impossible to set up networks from scratch or integrate devices without existing participants
Solution Approach 1:
The patent segments the network integration process into two independent phases: configuration data preparation (which can be done offline) and wireless transmission (which can be performed without existing network participants). This segmentation allows network settings to be prepared in advance and then transmitted to devices regardless of whether they are already integrated into a network.
Solution Approach 2:
The patent implements preliminary action by preparing configuration data before network integration is needed. The system determines network settings in advance and stores them for later wireless transmission, allowing devices to be configured and integrated without requiring existing network participants during the configuration process.
3Reliability
If one participant is integrated at a time using existing methods, then each device can be individually configured, but the integration of a large number of participants becomes extremely tedious
Solution Approach 1:
The patent merges multiple individual integration operations into a single wireless transmission operation. Configuration data is transmitted simultaneously to multiple field devices, combining what would otherwise require sequential individual operations into one parallel process that maintains reliability while dramatically improving productivity.

AI summary
The invention describes an automation engineering method for wireless transmission of at least a first piece of information (I) between at least one initiator (1) and a multiplicity of receivers (A, B, C,…, H) that are in a reception mode, comprising the following steps: – transmission of the first piece of information (I), which contains a command to bequeath the first piece of information and at least one further command, by the initiator (1) in a first communication pulse (K1); - reception of the first piece of information (I) by at least one receiver (A, B, C,…, H); – transmission of a further communication pulse (K1, K2, K3, …, Kn), which contains the identical first piece of information (I) to the first communication pulse (K1), by the at least one informed receiver (A, B, C,…, H) that received the previously sent communication pulse, and changing of the informed receiver(s) (A, B, C,…, H) to a confirmation mode; – repetition of the previously described method step until all receivers (A, B, C,…, H) have changed to the confirmation mode; – activation of at least one receiver (A', B', C',…, H') that is in the confirmation mode; – execution of the at least one further command that the received first piece of information (I) contains by the activated receiver (A', B', C',..., H'); and – changing of the activated receiver (A', B', C',…, H') to the reception mode; and a system that is suitable for performing the method according to the invention.
