The present invention relates to a remote control system of an electric equipment, and more specially, to a remote control system of an electric equipment constructed by blue tooth module and communication protocol.
Conventionally, remote controller is classified as two types by transmission manner. Type one is so called IR remote controller which is controlled by employing IR transmission. Such transmission manner of the IR remote controller has an orientation property and its transmission distance is shorter. The IR remote controller is generally applied to an electric appliance, such as TV set, video recorder, air conditioner, refrigerator, or audio equipment . . . etc.. Type two is so called RF remote controller which is controlled by employing RF transmission. Such transmission manner of the RF remote controller has without orientation property and its transmission distance is longer. The RF remote controller is generally applied to garage, safety chain, wireless switch, car safety . . . etc..
Presently, mass production of remote controller is above-mentioned remote controller by transmission manner.
Moreover, remote controller is also classified as two types by code format. Type one is so called constant code remote controller which is employed the same data code emitted by the constant code remote controller. The constant code remote controller is often applied to a less safety concern situation or place owing to simple data code. Type two is so called hopping code remote controller which is which is employed the different data code in twice emitted by the hopping code remote controller. The hopping code remote controller is often applied to a strictly safety concern situation or place owing to complicate, difficult finding data code and high cost.
In view of the only employing aforesaid IR remote controller, it is an object of this invention to provide a new remote control system of electric equipment for meeting the requirement. Moreover, wireless communication range of remote controller by employing a blue tooth module and communication protocol is broader and without orientation limit than the IR remote controller, and emitting angle of the IR remote controller is limited.

The blue tooth is a communication specification of data delivering among various digital equipments. In general, the blue tooth is applied to mobile phone, notebook computer, personal digital assistant (PDA), etc..
