Radiocommunication Routing for Large Surface Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiocommunication systems for monitoring large surfaces, such as construction sites or isolated houses, face issues like one-way communication from remote sensing probes, interference due to redundant signals, and complex path configurations, leading to inefficient reaction times and increased costs.
Innovation Solution
A method that allocates unique identifiers to transmitters, allowing for optimized message routing by analyzing headers to avoid unnecessary retransmissions and interference, enabling efficient communication paths and reducing radio frequency interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If beacons are used to retransmit signals to increase system range, then the coverage area is improved, but radio frequency interference and signal redundancy increase
Solution Approach 1:
The patent implements dynamic routing where intermediate stations adaptively forward messages based on real-time network conditions and message destination. Instead of static beacon retransmission, the system dynamically selects optimal transmission paths, reducing unnecessary RF transmissions and interference while maintaining coverage.
Solution Approach 2:
The patent extracts the retransmission function from dedicated beacons and distributes it to any intermediate station that receives a message. This eliminates the need for specialized beacon devices and reduces the number of active transmitters, thereby reducing RF interference while maintaining system range.
2Reliability
If communication paths are pre-registered in all stations, then communication reliability is improved, but system configuration complexity and cost increase
Solution Approach 1:
The patent implements self-organizing network formation where intermediate stations automatically learn and store routing information through message exchange. Instead of requiring manual pre-registration of all paths, the network self-configures as stations are added, reducing configuration complexity while maintaining reliable communication through automatic path discovery.
Solution Approach 2:
The patent performs preliminary routing setup automatically during initial message exchange rather than requiring manual configuration beforehand. The first message from central unit to a new station automatically establishes the routing path, and intermediate stations learn to forward messages along this path for future communications.
3Area of stationary object
If multiple intermediate stations are used for large area monitoring, then coverage is improved, but message retransmission time and system reaction time increase
Solution Approach 1:
The patent segments the message transmission into parallel paths through multiple intermediate stations. When the central unit needs to communicate with a distant station, the message can be forwarded through different intermediate stations simultaneously or through optimized multi-hop paths, reducing overall transmission time compared to sequential processing.
Solution Approach 2:
The patent implements dynamic message forwarding where intermediate stations immediately forward received messages to their designated next hop without waiting for confirmation or additional processing. This dynamic push-based approach minimizes idle time at each hop and reduces overall system reaction time.
4Difficulty of detecting and measuring
If remote sensing probes are used for monitoring, then detection capability is improved, but two-way communication capability deteriorates
Solution Approach 1:
The patent makes intermediate stations (including remote sensing probes) universal nodes that can both detect environmental changes and participate in two-way communication. Instead of having probes as simple sensors, they become full network participants that can receive commands from the central unit and send both alarm and status messages, enabling remote configuration and diagnostics.

AI summary
In order to monitor a large-dimension environment, a plurality of emitters is provided and a central emitter (1) allocates, to each of the emitters, an identifier allowing the identification of each emitter in the environment, a parent identifier that can transmit information to an emitter, and a child identifier which is the furthest away, the identifier of which has the largest value towards which an emitter can transmit. When an alert indicating a change in the environment is generated by one of the emitters and sent to the central emitter, said identifiers allow an optimum and secure transmission towards the central emitter, and likewise, when a message is sent from the central emitter towards an emitter.
