IED Email Notification System for Serial Data Bottleneck
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional intelligent electronic devices (IEDs) face limitations in data transfer capabilities due to serial-based communication protocols, which restrict the amount of data that can be transferred at once, leading to delays and inefficiencies in processing and data traffic.
Innovation Solution
The implementation of an Alarm/Notification email feature in IEDs that enables the sending of messages via Simple Mail Transfer Protocol (SMTP) for user-configurable events, with options for low and high importance levels, and the ability to queue and group notifications, along with encryption and secure messaging, to enhance data transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If serial-based communication protocols are used for data transfer, then device compatibility and ease of implementation are improved, but data transfer speed and efficiency deteriorate
Solution Approach 1:
The patent introduces an email notification system as an intermediary communication layer between the IED and external devices. Instead of relying solely on serial-based protocols, the system uses SMTP email notifications to transmit event data, bypassing the speed limitations of serial communication while maintaining compatibility with existing IED architectures.
2Device complexity
If serial-based communication protocols are used for data transfer, then protocol simplicity is improved, but data transfer speed deteriorates
Solution Approach 1:
The patent segments the communication process into two distinct channels: a simple serial-based control channel for device management and an email-based data channel for high-speed event notification. This segmentation allows each channel to be optimized for its specific function, maintaining protocol simplicity where needed while achieving high transfer speeds where required.
3Quantity of substance
If multiple serial requests are sent to transfer large amounts of data, then data completeness is improved, but processing delays increase
Solution Approach 1:
The patent merges multiple serial requests into a single email notification message. When an event occurs, the system consolidates all relevant event data into one comprehensive email message and transmits it through the SMTP protocol, eliminating the need for multiple sequential serial requests and significantly reducing processing delays.
4Device complexity
If conventional serial communication is used, then system simplicity is improved, but communication timeliness deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-configuring email notification parameters and templates within the IED. When an event occurs, the system immediately formats and sends the notification without requiring real-time processing delays, as the communication pathway and message structure are already prepared in advance.
