Solution Overview
Problem
In wireless communication systems, especially in industrial and energy management applications, battery-operated wireless communication devices face challenges in extending battery life due to varying power supply conditions and data transmission requirements, leading to inefficiencies in operation and maintenance costs.
Innovation Solution
A wireless communication device configured with a power storage unit, a power generator, and a device manager that acquires operation timing and power supply information to determine operational patterns, allowing it to switch between continuous and intermittent operation modes, and alter communication paths to optimize data transmission and extend battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication device operates continuously to ensure data transmission, then the data transmission reliability is improved, but the battery life deteriorates
Solution Approach 1:
The device dynamically adjusts its operation mode between continuous and intermittent based on power availability. The device manager monitors power storage levels and communicates with the server to coordinate operation timing, allowing the system to transition from static continuous operation to dynamic adaptive operation that extends battery life while maintaining transmission reliability when possible.
Solution Approach 2:
The device implements intermittent operation where data transmission occurs periodically rather than continuously. The device manager determines optimal transmission intervals based on power storage levels, and coordinates with the server to schedule data updates, reducing power consumption while maintaining essential data transmission functionality.
2Duration of action of moving object
If the device switches to intermittent operation to extend battery life, then the battery life is improved, but the data transmission timeliness deteriorates
Solution Approach 1:
The device manager continuously monitors power storage levels and provides feedback to adjust operation timing. The server also provides feedback about data urgency and system status, allowing the device to optimize transmission timing based on real-time conditions, balancing battery conservation with timely data transmission when power is available or urgent.
Solution Approach 2:
The device performs preliminary assessment of power availability and data urgency before determining transmission timing. The server preliminarily evaluates system status and provides guidance on transmission priorities, allowing the device to plan transmission schedules in advance that balance battery life extension with data timeliness requirements.
3Reliability
If the device changes communication paths to bypass power-constrained nodes, then the system reliability is improved, but the device complexity increases
Solution Approach 1:
The device manager acts as an intermediary that handles the complexity of communication path selection and coordination. It monitors power levels, determines when path changes are needed, and coordinates with the server to implement path changes, isolating the complexity from the core communication functions and making the system more manageable.

AI summary
According to an embodiment, a wireless communication device includes a determiner, and an executor. The determiner is configured to determine whether the wireless communication device can continue operation by a stored electric power in which remaining capacity changes according to operation of the wireless communication device for a predetermined period, based on information including an operation timing associated with a cycle in which a management server. The executor is configured to execute an operation in which the data is transmitted and received between the other wireless communication device and the management server via the wireless communication device when the wireless communication device is able to continue the operation, and otherwise, cause the wireless communication device to move into intermittent operation and causes the other communication device to transmit the data to the management server not via the wireless communication device.
