Power Line Data Transmission System Using AC Signal Modulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission systems, such as those using GSM and the internet, incur significant infrastructure costs and hardware expenditures, making them economically burdensome for remote communications.
Innovation Solution
A data transmission system utilizing a power line with a sender and receiver controller that processes alternating current signals to transmit data, where the sender controller modifies AC signals based on received data and the receiver controller converts these signals back into usable data, allowing for efficient data transfer without the need for additional infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless network systems like GSM or Internet are used for remote communication, then data transmission capability is improved, but infrastructure costs and hardware expenses increase significantly
Solution Approach 1:
The existing power line infrastructure is made to serve dual purposes: traditional electrical power distribution and data transmission. By enabling data signals to travel through the same wires that deliver electricity, the system eliminates the need for separate communication infrastructure, directly resolving the contradiction between transmission capability and infrastructure cost
Solution Approach 2:
The power line communication system utilizes the already-deployed electrical grid to provide data transmission services. Instead of requiring new infrastructure to be built and maintained, the system leverages the existing power distribution network, allowing it to serve itself for both power and communication needs
2Adaptability or versatility
If cable and modem hardware are installed for data transmission, then communication functionality is improved, but economic burden increases
Solution Approach 1:
The power lines are transformed from single-function (power only) to multi-function (power plus data transmission). This eliminates the need for dedicated communication hardware like cables and modems, reducing economic burden while maintaining communication functionality
Solution Approach 2:
The power line acts as an intermediary medium that carries both electrical energy and data signals. By using the existing power infrastructure as a mediator for data transmission, the system avoids the need for separate communication hardware, reducing deployment costs
Data Source
AI summary
A data transmission system includes a sender, at least one receiver, a sender controller, and a receiver controller. The sender controller receives an AC signal from an AC power source via a first AC input port, receives data from the sender via a first data port, and processes the received AC signal according to the received data, and outputs a processed AC signal via a first AC output port. The receiver controller receives the processed AC signal from the sender controller via the second AC input port, powers the at least one receiver using the processed AC signal via the second AC output port, and converts the processed AC signal to corresponding data and transmits the data to the at least one receiver via a second data port.
