Title:
EQUIPMENT SYSTEM AND TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/045557
Kind Code:
A1
Abstract:
Provided is air-conditioning system that can suppress transmission errors when non-air-conditioning data is superposed on air-conditioning data by means of a simple configuration. The air-conditioning system (1), which performs asynchronous communication, is provided with: an air-conditioning outdoor unit and an air-conditioning indoor unit that each have a transmission device (71b, 75b); and a communication line. The transmission device (75b) superposes non-air-conditioning data on air-conditioning data avoiding the signal change timing of the air-conditioning data when both low-frequency air-conditioning data and high-frequency non-air-conditioning data are caused to flow to a dedicated communication line (51).
