Emergency Alert Wireless Terminal Automatic Communication Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems used in quick service restaurants, staff members with general settings face challenges in reliably notifying others of emergencies due to uncertainty about the control of the emergency situation, inability to identify the emergency alert sender, and difficulty in initiating communication during panic situations.
Innovation Solution
Implementing a wireless communication system with terminals having emergency alert and connection request functions, where an emergency alert is broadcasted and a connection request signal is transmitted to put the alert sender in a communicable state, allowing automatic communication initiation even if the sender is unable to operate the intercom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminals with general setting are allowed to transmit emergency alerts, then emergency notification capability is improved, but reliability of communication establishment deteriorates because senders may be unable to operate the intercom during panic situations
Solution Approach 1:
The system enables self-service communication establishment by automatically initiating communication between the emergency alert sender and other terminals without requiring manual operation from the sender. The automatic communication initiation function detects when an emergency alert is transmitted and automatically establishes communication channels, allowing the system to serve itself rather than relying on the panicked sender to initiate contact.
Solution Approach 2:
The system performs preliminary actions by pre-establishing communication protocols and automatic initiation mechanisms before the emergency situation occurs. The automatic communication initiation function is pre-programmed to activate upon detecting an emergency alert transmission, ensuring that communication channels are established immediately without requiring the sender to perform any actions during the crisis.
2Ease of operation
If manual operation is required to initiate communication after emergency alert, then communication control is improved, but ease of operation deteriorates because senders cannot operate during panic
Solution Approach 1:
The system eliminates the need for manual operation by implementing self-service automatic communication initiation. When an emergency alert is transmitted, the system automatically detects this event and initiates communication channels without requiring the sender to press buttons or perform any manual actions, thus serving the communication establishment function automatically.
Solution Approach 2:
The system introduces an intermediary automatic communication initiation function that mediates between the emergency alert transmission and the communication establishment. This intermediary function detects the emergency alert and automatically bridges the communication gap, removing the need for direct manual intervention from the panicked sender.
3Productivity
If limited communication channels are assigned to general terminals, then channel management is improved, but productivity deteriorates because multiple terminals cannot communicate simultaneously
Solution Approach 1:
The system applies dynamics by making communication channels dynamically allocable rather than statically assigned. The channel assignment mechanism can adaptively allocate channels based on current system conditions and emergency requirements, allowing the same channel to be reused by different terminals at different times, thereby increasing simultaneous communication capacity without proportionally increasing the total number of channels.
Solution Approach 2:
The system implements periodic action through time-division multiplexing of communication channels. Channels are allocated to different terminals in periodic cycles, allowing multiple terminals to access the same physical channel at different time intervals. This enables multiple simultaneous communications to occur through temporal separation, increasing productivity without requiring proportional channel expansion.

AI summary
There is provided a wireless communication system which solves various problems generated by allowing a terminal to transmit an emergency alert. In the wireless communication system, an emergency alert terminal (210) includes an emergency alert section (211) for broadcasting an emergency alert, and a connection request terminal (220) includes a connection request section (221) for transmitting a connection request signal to request connection to an emergency alert terminal (210). The emergency alert terminal (210) includes an automatic communication initiation section (212) for allowing a communication with the connection request terminal (220) upon transmission of the connection request signal from the connection request section (221) of the connection request terminal (220) after transmission of the emergency alert.
