Abnormal Situation Alarming System with Time Calculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abnormal situation alarming systems struggle to enable staff to handle abnormal situations on an ad hoc basis effectively, as they often fail to accurately determine the time allowable for handling such situations due to incomplete information and complex circumstances.
Innovation Solution
An abnormal situation alarming system that includes a detection unit to identify abnormal situations, an acquisition unit to gather information about the circumstances of the location where the abnormal situation occurred, a calculation unit to determine the time allowable for handling the situation, and an alarming unit to provide timely alerts to staff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an alarm is given to notify staff of an abnormal situation, then staff can recognize the occurrence immediately, but staff cannot accurately determine the time allowable for handling the situation
Solution Approach 1:
The system performs preliminary calculation of the time allowable for handling the abnormal situation before the alarm is given. The calculation unit computes the time allowable based on pre-stored train operation information and the detected abnormal situation details, so that when staff receive the alarm, the time information is already ready and can be immediately conveyed to them.
Solution Approach 2:
The calculation unit acts as an intermediary between the detection unit and the alarm notification. It receives detection results, acquires relevant information (such as train operation schedules), calculates the time allowable, and then provides this calculated time information to the alarm notification system, thereby mediating the information flow to ensure completeness.
2Ease of operation
If staff manually check the bulletin board to calculate the time allowable, then they can determine the time based on current display information, but they cannot accurately handle situations involving passing trains or complex circumstances
Solution Approach 1:
The system replaces the manual mechanical process of staff checking the bulletin board and calculating time differences with an automated electronic calculation unit. The calculation unit electronically retrieves train operation information, processes the abnormal situation details, and computes the time allowable, eliminating human error and manual limitations in handling complex cases such as passing trains.
Solution Approach 2:
The system changes the parameter of time calculation from manual estimation based on bulletin board display to automated precise calculation based on comprehensive train operation information. By transforming the calculation process from human-based to system-based, the accuracy and reliability of time determination is significantly improved.
3Device complexity
If the system only provides basic alarm notification, then the system remains simple, but it cannot enable staff to cope with abnormal situations on an ad hoc basis
Solution Approach 1:
The system achieves multi-functionality by integrating multiple capabilities into a single alarm notification system: it not only provides basic alarm notification but also automatically calculates and provides the time allowable for handling, acquires relevant contextual information, and adapts to different types of abnormal situations. This universal design enables staff to handle various abnormal situations effectively without requiring multiple separate systems.

AI summary
An abnormal situation alarming system includes a detection unit that detects an abnormal situation, an acquisition unit that acquires, when the abnormal situation is detected, information representing the circumstances of the location where the abnormal situation occurred, a calculation unit that calculates the time allowable for handling the abnormal situation from a detection result of the abnormal situation and an acquisition result of the information, and an alarming unit that gives an alarm of the detection result of the abnormal situation and a calculation result of the time.
