Solution Overview
Problem
In data transmission systems with multiple devices, unintended parallel data transmission can lead to different interpretations and faulty data, causing devices to send impermissible actions, due to the use of different communication protocols among data transmission devices.
Innovation Solution
Preventing data transmission via the second data interface by switching off the power supply to the second data interface, using an interrupting device such as a switch, to ensure that only one data transmission device is actively used, thereby avoiding mutual influence and ensuring reliable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple data transmission devices are used in parallel for redundancy and compatibility, then system reliability and adaptability are improved, but unintended parallel transmission causes data interpretation errors and faulty actions
Solution Approach 1:
The patent extracts and removes the unused data transmission device from active operation by switching off its power supply. This prevents the unused device from transmitting unintended data that would cause interpretation errors, while maintaining the device in the system for redundancy purposes. The solution separates the functional activation state from the physical presence in the system.
Solution Approach 2:
The patent applies preliminary anti-action by proactively switching off the power supply to the unused data transmission device before it can transmit erroneous data. This preventive measure stops the harmful parallel transmission at its source, preventing data interpretation errors and faulty actions before they occur.
2Reliability
If power supply is switched off to prevent unintended transmission, then data integrity is improved, but energy efficiency worsens due to continuous power consumption of standby devices
Solution Approach 1:
The patent implements dynamic power management by switching the power supply state of data transmission devices based on their operational status. When a device is not actively transmitting data, its power supply is switched off to prevent unintended transmission. When needed, power is restored. This dynamic approach balances data integrity with energy efficiency.
3Speed
If unused data transmission devices remain powered on for quick failover, then switching speed is improved, but system stability deteriorates due to potential unintended transmissions
Solution Approach 1:
The patent applies preliminary action by maintaining unused data transmission devices in a pre-configured but powered-off state. All configuration and setup are completed in advance, so when failover is needed, the device can be quickly reactivated without reconfiguration. This preliminary preparation enables fast switching while maintaining system stability through controlled power management.

AI summary
The invention relates to a method for operating a data transfer system (2, 36, 50, 68, 72), in which a first data transfer device (4, 6, 52) is connected to a first data line (14, 16, 64), which is connected to a first data interface (10, 12, 62), a second data transfer device (4, 6, 52) is connected to a second data line (14, 16, 64), which is connected to a second data interface (10, 12, 62), and data can be transferred via the first data interface (10, 12, 62). In order to achieve reliable operation of the data transfer system (2, 36, 50, 68, 72), according to the invention a transfer of data via the second data interface (10, 12, 62) is prevented.
