Dual-Mode Communication Device for Movable Object Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information transmission systems for movable objects, such as vehicles, face challenges in accurately collecting and transmitting data across wide areas, especially in rural or offshore regions, due to high costs and limited coverage of mobile communication networks, which restricts the frequency and volume of data transmission.
Innovation Solution
An information transmission system equipped with a communication connection device that includes both a low-power wide-area (LPWA) communicator for regular data transmission and a short-range wireless communicator for higher volume or frequency data transfer when the object is not in use or at specific locations, allowing for more efficient data collection and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobile communication network is used for data transmission, then data transmission volume and frequency are improved, but communication cost increases
Solution Approach 1:
The communication system is segmented into two distinct communication modules: a mobile communication module for high-volume data transmission and a short-range wireless communication module for low-cost transmission. The system selectively uses each module based on data volume requirements and cost considerations, thereby resolving the contradiction between transmission volume and cost.
2Productivity
If mobile communication module is incorporated, then data transmission capability is improved, but device cost increases
Solution Approach 1:
The communication device incorporates two separate communication modules instead of relying solely on a mobile communication module. This segmentation allows the system to use the cheaper short-range wireless module for routine transmissions, reducing the need for expensive mobile communication resources while maintaining the capability for high-volume transmission when necessary.
3Loss of energy
If LPWA communication is used, then communication cost is reduced, but data transmission volume is limited
Solution Approach 1:
The system dynamically selects between LPWA communication and short-range wireless communication based on real-time conditions such as data volume requirements and network availability. This dynamic adaptation allows the system to maximize cost efficiency while ensuring adequate data transmission capacity when needed.
4Productivity
If short-range wireless communication is used, then data transmission volume and frequency are improved, but coverage area is limited
Solution Approach 1:
The system merges two communication technologies with complementary characteristics: mobile communication provides wide-area coverage while short-range wireless communication provides high-speed data transmission. By combining these technologies in a dual-module architecture, the system achieves both wide coverage and high transmission capability.

AI summary
An information transmission system includes a communication connection device and a server. The communication connection device includes a use determination unit, a first communicator, a second communicator, and a communication control unit. The use determination unit determines whether a movable object is in use. The second communicator communicates with the server for a larger volume of data than the first communicator at a time, or communicates with the server more frequently than the first communicator. The communication control unit causes the second communicator to transmit, selectively from transmission information, specific transmission information including predefined movable object information to the server when the use determination unit determines that the movable object is not in use and the second communicator is enabled to communicate with a communication base station.
