Far end remote control method and system by short message and bluetooth function operation

Abstract

A far end remote control method and system by a short message and Bluetooth function operation are used to control output/input devices at a far end. The system mainly comprises a cellular phone, controlling device and controlled devices. Here, the method comprises the following steps: first, a cellular phone transmits a short message control command to a controlling device through a cellular phone network; the controlling device searches a controlled device appointed in the command; the controlling device builds a Bluetooth Serial Port Profile connection with the controlled device after the appointed controlled device is found; the controlling device transmits the short message control command to the controlled device through the connection; the controlled device controls an output or input device after receiving the command; the controlled device transmits an execution result back to the controlling device; the controlling device reports the execution result back to the cellular phone by a short message; the controlling device disconnects the connection with the controlled device and waits for a next control command after the report is completed. Thereby, the control range can be expanded to the all places in the world that the cellular phone is applicable. And, the controlled device can built a temporary network with the controlling device, the structure will not be changed even if the number of the controlled devices is increased or decreased.
