Solution Overview
Problem
The matching between the first interface and the first channel in a signal transmission apparatus affects the quality of optical signals, necessitating a commissioning process to ensure optimal alignment, which is often manual and time-consuming.
Innovation Solution
A signal transmission apparatus with a service processing module and optical module that includes a first interface and channel, where an initial signal is sent to determine a parameter adjustment policy based on transmission status, using a signal processing module to automate the commissioning process, including options for indirect connections through optical fibers or splitting modules, and utilizing additional channels and modules for comprehensive indicator calculation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual commissioning is used to match the first interface and first channel, then matching accuracy can be achieved, but commissioning time increases and efficiency decreases
Solution Approach 1:
The signal transmission apparatus performs self-commissioning by automatically sending initial signals through the first interface and first channel, obtaining modulated signals, calculating transmission indicators, and adjusting parameters without requiring manual intervention. The system uses its own resources (signal processing module, optical module) to complete the commissioning process autonomously.
Solution Approach 2:
The commissioning process incorporates feedback mechanisms where the signal processing module obtains transmission indicators based on modulated signals received from the first channel, compares these indicators against criteria, and automatically adjusts parameters accordingly. This closed-loop feedback enables automated optimization of the interface-channel matching.
2Productivity
If automated commissioning is implemented, then commissioning time is reduced and efficiency is improved, but system complexity increases
Solution Approach 1:
The commissioning functionality is merged with the existing signal transmission components. The signal processing module integrates the functions of sending initial signals, obtaining modulated signals, calculating transmission indicators, and adjusting parameters. This consolidation reduces overall system complexity compared to having separate commissioning equipment.
Solution Approach 2:
The signal transmission apparatus performs multiple functions: normal signal transmission and automated commissioning. The same hardware components (service processing module, optical module, signal processing module) are used for both operations, making the system multi-functional and reducing the need for additional dedicated commissioning equipment.
3Measurement precision
If comprehensive indicator calculation is performed using additional channels and modules, then parameter adjustment accuracy is improved, but device complexity increases
Solution Approach 1:
The commissioning process is segmented into distinct functional stages: sending initial signals, obtaining modulated signals, calculating transmission indicators, and adjusting parameters. Each stage is handled by specific modules (signal processing module for signal handling, optical module for optical processing), making the complex overall process manageable through modular segmentation.
