IoT Communication Device Dual-Unit Switching for Signal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IoT systems rely on a single communication means to transmit data to a cloud server, making them vulnerable to communication failures due to environmental deterioration, which can result in data transmission failures.
Innovation Solution
A communication device equipped with multiple communication units that switch between different communication methods based on radio field strength thresholds, ensuring stable data transmission to an external server by using a first communication unit when strength is above a threshold and switching to a second unit when it falls below, and determining communication feasibility through both radio field strength and response signal reception.

Engineering Contradiction Analysis
1Device complexity
If a single communication means is used to transmit data to the cloud server, then the device complexity is reduced, but the reliability of data transmission deteriorates when communication environment deteriorates
Solution Approach 1:
The communication device is divided into multiple independent communication units (first communication unit and second communication unit), each capable of transmitting data independently. This segmentation allows the system to switch between different communication paths, thereby maintaining reliability even if one path fails due to environmental deterioration.
Solution Approach 2:
The system monitors communication environment parameters (such as signal strength, interference levels) and dynamically switches between communication means based on these parameter changes. When the communication environment deteriorates below a certain threshold, the system transitions from the first communication unit to the second communication unit, maintaining transmission reliability through parameter-driven adaptation.
2Reliability
If multiple communication units are provided to ensure stable transmission, then the reliability of data transmission is improved, but the device complexity increases
Solution Approach 1:
Both the first and second communication units are designed with universal functionality to transmit output signals from external devices to the cloud server. They share common control logic and can perform the same core function, reducing the need for separate specialized systems and thereby limiting the increase in device complexity.
Solution Approach 2:
The communication device includes a control unit that automatically monitors communication environment parameters and autonomously decides when to switch between communication units without requiring external intervention. This self-service capability simplifies the overall system architecture by eliminating the need for complex manual control mechanisms while maintaining high reliability.
3Adaptability or versatility
If communication switching based on radio field strength is implemented, then the adaptability to communication environment changes is improved, but the complexity of communication control increases
Solution Approach 1:
The communication control unit continuously monitors radio field strength parameters and uses this feedback to dynamically adjust the communication path. When the measured field strength falls below a predetermined threshold, the system automatically switches from the first communication unit to the second communication unit. This feedback-driven approach enables adaptability to environmental changes while maintaining relatively simple control logic.

AI summary
A communication device 10 comprises a control unit 11b, a first communication unit 11, a second communication unit 12, and a communication control unit 11da. The control unit 11b acquires output signals from sensors 21a to 21d. The first communication unit 11 and the second communication unit 12 transmit the output signals acquired by the control unit 11b to a cloud server 31. The communication control unit 11da uses the first communication unit 11 to communicate with the cloud server 31 when the radio field strength of the signal transmitted from the first communication unit 11 to the cloud server 31 is over a specific threshold value, and switches from communication using the first communication unit 11 to communication using the second communication unit 12 when the radio field strength is at or below the specific threshold value.
