Data Collector Relay for Radio Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In decentralized local radio systems, data collectors face challenges in ensuring reliable data transmission to a remote control center due to failures in mobile radio connections, leading to energy inefficiencies and potential disruptions in the radio transmission network.
Innovation Solution
Implementing a method where data collectors check the mobile radio communication path connection and, if unsuccessful, resend data telegrams via the local radio network to neighboring collectors, which then forward them to the control center, thereby acting as repeaters to ensure data delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data collectors use mobile radio communication paths to transmit data to the control center, then transmission speed and efficiency are improved, but reliability deteriorates due to connection failures
Solution Approach 1:
The patent introduces neighboring data collectors as intermediary nodes that can relay data telegrams when the primary mobile radio communication path fails. These intermediaries enable alternative transmission routes through the local radio network, ensuring data delivery even when direct connections to the control center are unavailable.
Solution Approach 2:
The patent adds a spatial dimension to data transmission by utilizing the local radio network infrastructure as an alternative pathway. When mobile radio connections fail, data can be routed through neighboring collectors in different physical locations, creating a multi-dimensional transmission approach that combines direct mobile links and indirect local network routes.
2Reliability
If data collectors continuously monitor and resend data telegrams, then reliability of data delivery is improved, but energy consumption increases
Solution Approach 1:
The patent implements feedback mechanisms where data collectors monitor the status of mobile radio connections and adjust their behavior accordingly. When connection failures are detected, collectors automatically switch to resend modes using the local radio network. This feedback-driven approach ensures reliable data delivery while avoiding unnecessary continuous monitoring and resending operations that would waste energy.
Solution Approach 2:
The patent makes the data transmission strategy dynamic by allowing data collectors to adapt their behavior based on real-time connection conditions. Collectors can switch between direct mobile transmission and indirect local network relay modes depending on availability, optimizing the balance between reliability and energy consumption rather than using a fixed approach.
3Reliability
If data collectors act as repeaters to ensure data delivery, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent enhances the universality of data collectors by enabling them to perform multiple functions: acting as primary data transmission nodes when mobile connections are available, and functioning as repeaters when connections fail. This multi-functionality is achieved through software-controlled mode switching, allowing a single device type to handle various transmission scenarios without requiring separate specialized hardware for each role.

AI summary
A method for transmitting data from a local radio network (4) in a building (5) to a remote central station (7) and a data collector set up for carrying out the method are described. In the method, the data from terminal devices (2) are transmitted to data collectors (3) installed in the building (5) and are further transmitted by the data collectors (3) to the central station (7), where the data from the terminal devices (2) are stored. Data telegrams (50) containing the data of the terminal device (2), which were transmitted by a terminal device (2) in a radio communication (6) of the local radio network (4), are received by a data collector (3) installed within radio range of the terminal device (2), and the data collector (3) forwards the data to the central station (7) via a mobile communication link (8).It is provided that the data collector (3) checks for a connection to be established from the data collector (3) to the central unit (7) via the mobile communication link (8) and, if a mobile data transmission (9) via the mobile communication link (8) with the central unit (7) does not take place, the data collector (3) as a data collector (3) without mobile data transmission (9) from terminal devices (2) retransmits data telegrams (50) received via the radio communication (6) of the local radio network (4).
