Operating terminal and facility device control system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facility device control systems are limited in the number of devices they can operate due to power supply capacity and require multiple operating terminals, making it difficult to control all devices from a single terminal, especially when devices are located far away.
Innovation Solution
An operating terminal that includes an information transmitting unit to share connected-device information with other terminals, an operation receiving unit to process user commands, and a control command transmitting unit to determine and send commands to the appropriate devices, allowing for increased operable facility devices across multiple terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operating terminals are installed to control all facility devices, then the number of operable devices per terminal is limited, but the system complexity and user operation difficulty increase
Solution Approach 1:
The patent merges the control functions of multiple operating terminals by enabling each terminal to access and control facility devices connected to other terminals through information sharing mechanisms. This combines the operational capabilities of multiple terminals into a unified system where any terminal can control any device.
Solution Approach 2:
Each operating terminal is designed with multi-functionality to not only control locally connected facility devices but also to control facility devices connected to other terminals. This universal control capability eliminates the need for multiple specialized terminals.
2Reliability
If facility devices are connected to a single operating terminal via cable, then connection reliability is ensured, but the number of connectable devices is limited by power supply capacity
Solution Approach 1:
The patent introduces other operating terminals as intermediary devices that relay control commands between the user's terminal and facility devices connected to different terminals. This mediator approach allows indirect control without requiring direct physical connection or additional power capacity at the source terminal.
3Ease of operation
If each operating terminal controls only locally connected facility devices, then device management is simplified, but user convenience deteriorates when operating remote devices
Solution Approach 1:
The patent implements preliminary action by having operating terminals pre-share their connected facility device information with other terminals in advance. This allows users to directly select and control remote devices without needing to physically locate or access the terminal where the device is connected, eliminating time loss.

AI summary
An operating terminal includes: a connected-device information transmitting unit transmitting first connected-device information to another operating terminal, the first connected-device information being information on a facility device connected to the operating terminal; a connected-device information obtaining unit obtaining second connected-device information from the another operating terminal, the second connected-device information being information on a facility device connected to the another operating terminal; an operation receiving unit receiving an operation for being performed on a facility device connected to the operating terminal and a facility device connected to the another operating terminal; and an air conditioning control command transmitting unit determining, from the first connected-device information and the second connected-device information, a destination of a control command and transmitting the control command to the destination, the control command representing content of an operation received by the operation receiving unit.
