Smart Meter Data Transmission Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods for smart consumption meters face challenges such as interference in shared frequency bands, reduced transmission quality, and increased power consumption due to frequent data dispatches and reception standby times, which affect the durability of battery-operated meters.
Innovation Solution
A method where the terminal and data collector intermittently or constantly operate in receive mode, with the terminal initiating communication by sending messages to adjust transmission based on the message content, allowing for selective continuation, interruption, or termination of data transmission, thereby reducing power consumption and improving transmission quality and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal frequently operates in reception standby mode to improve transmission quality and safety, then the probability of successful transmission increases, but power consumption increases and battery life decreases
Solution Approach 1:
The patent applies preliminary action by having the terminal send a message to the data collector before actual data transmission to inquire about transmission conditions. This allows the terminal to assess whether conditions are favorable for transmission without being in constant reception standby mode, thereby reducing power consumption while maintaining transmission reliability.
2Reliability
If the terminal sends data frequently to improve data freshness and transmission safety, then transmission quality improves, but battery life decreases due to increased power consumption
Solution Approach 1:
The patent implements feedback by having the data collector send response messages to the terminal indicating whether transmission conditions are favorable. This feedback mechanism allows the terminal to adjust its transmission strategy dynamically, sending data only when conditions are good, thereby maintaining transmission safety while extending battery life by avoiding unnecessary transmission attempts.
3Use of energy by moving object
If the terminal operates in idle phase most of the time to reduce power consumption, then battery life extends, but transmission responsiveness decreases
Solution Approach 1:
The patent applies periodic action by having the terminal periodically check transmission conditions by sending messages to the data collector while operating in idle phase most of the time. This periodic checking mechanism maintains transmission responsiveness without requiring the terminal to be in constant reception standby mode, thus extending battery life while preserving the ability to transmit data promptly when needed.
Data Source
AI summary
Data are transmitted by radio between a terminal and a data collector. The data collector is intermittently or constantly in receive mode. The terminal attempts, from an idle phase, to set up a communication with the data collector in order to send all or some of the data to the data collector and/or to receive them from the data collector. Alternatively, the data collector attempts to set up a communication with the terminal in order to send all or some of the data to the terminal and/or to receive them from the terminal. The setup of the communication is followed by the terminal sending a message to the data collector and the data collector, after receiving the message, continuing, interrupting and/or terminating the transmission of the data during communication on a basis of the content of the message.
