Solution Overview
Problem
Existing air conditioner systems face challenges in wireless communication due to increased network scale, leading to high costs and calculation loads, making it difficult to apply complex routing schemes, which results in delayed signal processing and failure to rapidly handle signal blockages, affecting normal operation.
Innovation Solution
The system configures one unit as a master node and the others as slave nodes, with slave nodes storing information on parent and child nodes in a routing table, using unicast or broadcast schemes for data transmission based on node relationships, and implementing a simplified routing structure to reduce network traffic and load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex routing scheme is applied to wireless communication in air conditioner systems, then signal transmission capability is improved, but calculation load and cost increase
Solution Approach 1:
The patent segments the routing function by dividing nodes into master nodes and slave nodes. Master nodes store complete routing tables while slave nodes store only simplified routing information (parent and child node addresses). This segmentation allows complex routing capabilities to be distributed, reducing the calculation load on individual slave nodes while maintaining overall system signal transmission capability.
2Adaptability or versatility
If the network scale is increased to accommodate more air conditioner units, then system coverage is improved, but communication cost and complexity increase
Solution Approach 1:
The patent enables network expansion by segmenting routing functionality. As new units are added to the network, they can be configured as slave nodes with simplified routing tables, allowing the network to scale without proportionally increasing the complexity and cost for each node. The master nodes handle the complexity of managing the expanded network topology.
3Adaptability or versatility
If wireless communication is used to allow distributed installation, then installation flexibility is improved, but signal processing time increases
Solution Approach 1:
The patent reduces signal processing time by segmenting the routing information storage. Slave nodes store only essential routing information (parent and child node addresses) rather than complete routing tables, enabling faster local routing decisions. This segmentation allows wireless communication to maintain fast response times despite distributed installation across multiple locations.
4Stability of the object's composition
If a tree structure with master, slave, and repeater nodes is implemented, then network organization is improved, but software complexity and storage requirements increase
Solution Approach 1:
The patent simplifies the tree structure implementation by segmenting the node types. Instead of implementing three distinct node types (master, slave, repeater) with different software configurations, the patent uses only master and slave nodes. Slave nodes store simplified routing information, eliminating the need for complex repeater software while maintaining stable network organization through the hierarchical master-slave relationship.

AI summary
Disclosed is an air conditioner. An air conditioner includes: a plurality of units including an outdoor unit and an indoor unit, and distributed at a plurality of layers; and a control unit configured to monitor and control the plurality of units, wherein the control unit and the plurality of units include a communication unit configured to transmit/receive data in a wireless communication scheme, respectively, one of the plurality of units is configured as a master node, and remaining units except for the unit configured as the master node are configured as slave nodes, respectively, so that the slave node stores information on an upper parent node and a lower child node in a routing table to transmit data. Since a plurality of units in the air conditioner transmit/receive data in a wireless communication scheme, direction communication between an indoor unit and an indoor unit and between the indoor unit and an outdoor unit may be performed regardless of an installation environment, and the indoor may directly communicate with the control unit without the outdoor unit. In order to transmit data in a wireless scheme, the plurality of units in the air conditioner are operated as one node during transferring the data, respectively, a plurality of nodes do not include a routing table and stores only information on a parent node and a child node which are directly connected so that a routing structure may be simplified. Although the air conditioner includes a plurality of units, it is easy to install the units and to configure a wireless network in the present invention. When the units perform functions of the node, load of each node is reduced. Network traffic of the air conditioner is reduced by minimizing unnecessary routing table so that the transmission efficiency is improved.
