AIR-CONDITIONER CONTROL SYSTEM USING PSTN

摘要

PURPOSE: An air-conditioner control system using PSTN is provided to control one or the entire air-conditioners by assigning an ID to multiple air-conditioners connected to the same phone number, and control a detailed function of the air-conditioners. CONSTITUTION: An electronic device(100) drives a control program to output each state of multiple air-conditioners and input a control command. A control command signal inputted through the electronic device(100) is transmitted to a PSTN through a transmitter(200) connected in series to a serial port of the electronic device(100). The transmitter(200) receives the control command inputted through the electronic device(100) and transmits it to an air-conditioner. The control command signal reaches a phone number through the PSTN, and a receiver(300) of the air-conditioner receives the control command signal. The receiver(300-302) transmits the control command to the air-conditioner.
