Solution Overview
Problem
Existing air-conditioning systems cannot perform ganged control of air-conditioning facilities and general-purpose devices, limiting integrated control and energy saving performance.
Innovation Solution
An air-conditioning system with a general-purpose device controller that receives signals from both air-conditioning facilities and general-purpose devices, transmitting control signals via dedicated and open communication lines to perform integrated control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control programs are updated based on area situations, then localized control is achieved, but integrated control of air-conditioning facility and general-purpose device cannot be performed
Solution Approach 1:
The control device maintains the ability to perform localized control of air-conditioning facilities while simultaneously acquiring and processing information from general-purpose devices. It can execute control programs that consider area situations and coordinate control across both air-conditioning and general-purpose devices, achieving integrated control without sacrificing localized control capabilities.
2Reliability
If separate communication lines are used for air-conditioning facility and general-purpose device, then communication protocols can be optimized for each device type, but integrated control cannot be performed
Solution Approach 1:
The system segments communication into two separate transmission lines: a dedicated transmission line for air-conditioning facilities using a first communication protocol, and an open transmission line for general-purpose devices using a second communication protocol. The control device is configured to issue unified control commands that are appropriately routed and interpreted for each device type, enabling ganged control while maintaining protocol-specific optimization and reliability.

AI summary
An air-conditioning system includes a general-purpose device controller which controls a general-purpose device and an air-conditioning facility. The general-purpose device controller includes a processing configuration unit which receives a first signal corresponding to the air-conditioning facility and a second signal corresponding to the general-purpose device and transmits a control signal which controls the air-conditioning facility and the general-purpose device based on the first signal and the second signal. The processing configuration unit is configured to designate the air-conditioning facility which is a first control target, with a management address which is included in the first signal and designate the air-conditioning facility, designate the general-purpose device which is a second control target, with an input/output port number which is included in the second signal and designate the general-purpose device, and transmit the control signal which performs ganged control of the first control target and the second control target.
