More Information
Summary:An air conditioner control system using a PSTN (Public Switched Telephone Network) and a method for operating the same. The system and method enable a remote control operator to partially or entirely control a plurality of air conditioners through the PSTN by connecting receiver modules to the air conditioners having assigned unique IDs (Identities) and classifying the air conditioners commonly using the same telephone line. In an electronic device, a control program is driven to control and monitor the air conditioners. A transmitting module connected to the electronic device in serial converts and codes a control command signal into a DTMF (Dual Tone Multi-Frequency) signal and transmits the DTMF signal to a receiving module connected to a corresponding air conditioner through the PSTN such that the air conditioner can be remotely controlled. Since the air conditioners within a large-sized building can be partially or entirely controlled, convenience and efficiency of remote control can be improved and time, manpower and cost for controlling and managing the air conditioners can be saved.
