Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a reliable method to confirm the execution of commands for reducing electrical power consumption in passenger transport vehicles, particularly in rail transport, which is crucial for balancing electricity supply and demand.
Innovation Solution
A method involving a command signal modulated with a reference signal is sent to the temperature regulation system of passenger transport vehicles. The method includes obtaining a signal of the power consumed by the air conditioning means in response to the reference signal and confirming the execution of the consumption reduction command based on the characteristics of this signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If remote real-time control of air conditioning systems is implemented, then electricity consumption can be reduced during peak periods, but there is no reliable method to confirm execution of the reduction commands
Solution Approach 1:
The system implements feedback by modulating the command signal with a reference signal and then detecting this modulated signal in the power consumption measurement. The management company sends a command signal modulated with a reference signal to the air conditioning system, and the confirmation is obtained by measuring the power consumption and extracting the reference signal component, thereby verifying that the command was received and executed.
Solution Approach 2:
The reference signal acts as an intermediary carrier that embeds the command information within the power consumption signal. By modulating the command signal with the reference signal and then detecting it in the power consumption, the system creates a reliable intermediate verification mechanism that proves command execution without requiring direct communication feedback from the air conditioning system.
2Productivity
If air conditioning power is reduced to balance electricity supply and demand, then load management is achieved, but compliance verification becomes difficult
Solution Approach 1:
The system provides automatic feedback by continuously monitoring power consumption and comparing it against the modulated command signal. The management company can verify compliance in real-time by detecting the reference signal component in the power consumption measurement, eliminating the need for manual verification or trust-based compliance reporting.
Solution Approach 2:
The air conditioning system itself provides the compliance verification data through its power consumption signal. By modulating the command signal with a reference signal and detecting it in the power consumption, the system makes the compliance evidence self-evident in the operational data, requiring no additional verification equipment or manual reporting from the operator.
3Use of energy by moving object
If temperature regulation systems are controlled remotely, then fleet-wide consumption can be optimized, but reliable confirmation of individual vehicle compliance is lacking
Solution Approach 1:
The reference signal serves as an intermediary marker that is embedded in the command and then detected in the power consumption signal of each individual vehicle. This allows the management company to precisely verify compliance for each vehicle independently by detecting the presence and characteristics of the reference signal in that vehicle's power consumption measurement.
