Solution Overview
Problem
Communication systems for long transmission distances often face challenges in reducing electric power consumption while maintaining effective signal transmission.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed signal transmission is used for data communication, then communication speed is improved, but electric power consumption increases
Solution Approach 1:
The communication terminal dynamically switches between first and second operation modes based on communication requirements. The controller adjusts the operation mode in real-time, transitioning from high-speed mode (first operation mode) to low-speed mode (second operation mode) when appropriate, thereby optimizing the balance between communication speed and power consumption
Solution Approach 2:
The invention changes the signal transmission parameters by switching between different operation modes. In the second operation mode, the signal transmission speed and transition rate are reduced compared to the first operation mode, which directly lowers power consumption while maintaining functional communication capability
2Use of energy by moving object
If low-speed operation mode is used to reduce power consumption, then electric power consumption is reduced, but communication efficiency decreases
Solution Approach 1:
The communication system employs periodic switching between operation modes rather than continuous operation in one mode. The controller periodically evaluates communication needs and transitions between first and second operation modes, ensuring that low-speed power-saving mode is activated only when appropriate, thus maintaining overall communication efficiency while reducing average power consumption
3Length of stationary object
If signal transmission through capacitive elements is used for long distance communication, then transmission distance is extended, but power consumption increases
Solution Approach 1:
For long-distance communication through capacitive elements, the system dynamically adjusts operation modes based on distance and signal attenuation requirements. The controller switches to second operation mode when the communication distance is sufficient with lower speed, reducing power consumption while maintaining signal integrity over the extended distance

AI summary
To obtain a communication apparatus capable of reducing the consumption of electric power. A communication system according to the present disclosure includes a transmitter that generates a first signal including communication data and sends the first signal through a communication terminal in a first operation mode, and that generates a second signal including a predetermined first signal pattern and having a transition rate lower than the first signal and sends the second signal through the communication terminal in a second operation mode, and a controller that sets an operation mode for the transmitter to either of a plurality of operation modes including the first operation mode and the second operation mode.
