Air conditioning control device, air conditioning control method, and program using voice control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote voice control systems for air conditioners require high-performance mobile communication terminals with large memory and high throughput to store cross-reference tables and convert voice commands into control commands, and they struggle to specify the target air conditioner in systems with multiple air conditioners from different refrigerant groups.
Innovation Solution
An air conditioning control apparatus that includes a voice acquirer, an air conditioner specifier, a command generator, and a command transmitter, which acquires audio signals from a mobile terminal, specifies the target air conditioner, generates control commands, and transmits them to the air conditioner, using an air conditioner management table, a specification table, and a command conversion table to enable voice control without requiring high-performance terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice control is implemented using a mobile communication terminal, then user operability is improved, but the terminal requires high performance with large memory and high throughput
Solution Approach 1:
The patent extracts the complex voice command processing function from the mobile terminal and relocates it to the air conditioning system. The terminal only needs to capture voice input and transmit it to the air conditioning system, which then handles the cross-reference table lookup and command generation. This extraction resolves the contradiction by maintaining ease of operation while eliminating the performance burden from the terminal.
Solution Approach 2:
The air conditioning system acts as an intermediary between the simple mobile terminal and the complex control operations. The terminal sends voice input to the air conditioning system, which then uses its internal cross-reference tables to convert voice commands into appropriate control commands. This intermediary role allows the terminal to remain simple while still enabling sophisticated voice control functionality.
2Adaptability or versatility
If multiple air conditioners from different refrigerant groups are connected to the network, then system versatility is improved, but the complexity of specifying the target air conditioner increases
Solution Approach 1:
The patent segments the air conditioning system into distinct refrigerant groups, with each group having its own identification code. The cross-reference table is segmented to store mappings between voice commands and control commands specific to each refrigerant group. This segmentation allows the system to handle multiple diverse air conditioners while simplifying target specification through group-based identification rather than individual unit identification.
Solution Approach 2:
The patent applies local quality by creating refrigerant-group-specific cross-reference tables that contain voice-to-command mappings tailored to each group's characteristics. Each refrigerant group has its own localized set of control commands and voice interpretations, allowing the system to accommodate diverse air conditioners while maintaining simple user interaction through group-level abstraction.
Data Source
AI summary
An air conditioning control apparatus acquires an audio signal for controlling air conditioners (outdoor units and indoor units) from a mobile terminal via the Internet. The air conditioning control apparatus specifies from among the air conditioners at least one air conditioner to be controlled based on the acquired audio signal. The air conditioning control apparatus generates control commands for controlling the specified air conditioner based on the acquired audio signal. The air conditioning control apparatus transmits the generated control commands to the specified air conditioner.
