1Extent of automation
If conventional signal detection equipment is used, then basic signal detection is possible, but detailed signal analysis and automatic tracking of abnormal signals cannot be performed, requiring users to manually perform multiple tasks
Solution Approach 1:
The signal detection apparatus integrates multiple functions including signal reception, A/D conversion, profile matching for abnormal signal detection, and automatic tracking within a single device. The apparatus can detect both normal and abnormal signals, perform detailed analysis, and automatically track abnormal signals without requiring separate equipment for each function.
Solution Approach 2:
The apparatus pre-stores multiple signal profiles representing different signal characteristics in memory before operation. During signal detection, the received signal is immediately compared against these pre-prepared profiles, enabling rapid automatic identification and tracking of abnormal signals without requiring manual analysis or preparation.
2Measurement precision
If users manually analyze signal characteristics and perform detection tasks, then detailed analysis can be achieved, but it takes a long time to take countermeasures
Solution Approach 1:
The apparatus continuously monitors received signals and automatically compares them against stored profiles in real-time. When an abnormal signal is detected through profile matching, the system immediately generates feedback by identifying and tracking the abnormal signal, enabling rapid response without manual intervention while maintaining precise analysis through systematic comparison methods.
Solution Approach 2:
The apparatus replaces manual mechanical analysis processes with automated electronic signal processing. The A/D converter digitally converts received signals, and the profile matching unit automatically compares digital signals against stored profiles using electronic computation, eliminating the need for manual analysis while achieving both precision and speed.
3Productivity
If comprehensive signal analysis functions are added to detection equipment, then automatic detection capability improves, but device complexity increases
Solution Approach 1:
The signal processing function is divided into distinct modular units: a signal reception unit for receiving signals, an A/D signal processing unit for digital conversion, and a profile matching unit for abnormal signal detection. Each unit performs a specific function, improving detection efficiency while managing complexity through functional segmentation and modular design.

AI summary
A signal detection apparatus includes a signal reception unit, an Analog to Digital (A/D) signal processing unit, and a user interface unit. The signal reception unit receives an external signal. The A/D signal processing unit determines whether the received signal is an abnormal signal based on a plurality of signal profiles having different signal characteristics, and obtains the abnormal signal if, as a result of the determination, it is determined that the received signal is the abnormal signal. The user interface unit displays the abnormal signal.
