Solution Overview

Problem

Existing relays are unable to efficiently register and communicate with multiple types of detectors that use different communication protocols, limiting convenience and flexibility in disaster protection systems.

Innovation Solution

A relay system that distinguishes and registers first and second detectors with different communication protocols, allowing for increased capacity and efficient communication by sorting and managing the registration of both types separately, thereby enhancing convenience and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the relay uses a single communication protocol for registration, then the device complexity is reduced, but the adaptability to different detector types deteriorates

Engineering Contradiction:

Improvecompatibility with different detector typesVSAvoidprotocol management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the communication protocol handling by creating separate registration processes for first detectors (using first protocol) and second detectors (using second protocol). The relay device maintains separate protocol stacks and registration procedures for each detector type, allowing independent management of each protocol without interference. This segmentation enables the relay to support multiple detector types while keeping each protocol implementation relatively simple and maintainable.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the relay registers multiple types of detectors with different protocols, then the versatility improves, but the difficulty of detecting and measuring deteriorates

Engineering Contradiction:

Improvemulti-protocol detection capabilityVSAvoidprotocol identification and management difficulty

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements preliminary action by pre-configuring the relay device with multiple protocol stacks (first protocol stack and second protocol stack) before actual detector registration. The relay is prepared in advance to handle both first detectors and second detectors, with each protocol stack already configured and ready to operate. This preliminary preparation eliminates the need for complex runtime protocol detection and switching, simplifying the actual registration process.

AI summary

An object of the present disclosure is to improve convenience. A relay (3) is configured to relay communication between each of a plurality of detectors (2) and a receiver (1). The relay (3) includes a first communication unit (31) and a registration processor (363). The communication unit (31) is configured to perform communication with the plurality of detectors (2) which have been registered with the storage (33). The registration processor (363) is configured to perform a registration process of registering the plurality of detectors (2) with the storage (33). The registration processor (363) registers each of the plurality of detectors (2) with the storage (33) such that the plurality of detectors (2) are sorted according to whether each of the plurality of detectors (2) is a first detector (201) or a second detector (202). The second detector (202) is different from the first detector (201) in terms of a communication protocol.
