Abstract:
1. A remote control device being changeable between an unlocked state and a locked state, the remote control device comprising: a communicating unit adapted to communicate with and remotely control a controlled apparatus; an operating unit comprising an activating key for generating an activating signal and at least two different controlling keys for generating two different operating signals in response to user operation; and a processor electrically connected with the communicating unit and the operating unit, the processor configured for unlocking the remote control device from the locked state, such that the remote control device communicates with and remotely control the controlled apparatus, and configured for locking the remote control device into the locked state, such that the remote controlled apparatus is unabled to communicate with the controlled apparatus and cannot remotely control the controlled apparatus; wherein when the remote control device is in the locked state, the processor records the order of the different operating signals to form authenticating information after the activating signal is generated, and further unlock the remote control device if the authenticating information matches with a predetermined authenticating information; wherein the processor comprises a scanning module, a recording module, an authenticating module and a controlling module, the scanning module is configured to generate a first scanning signal if the activating key generates an activating signal and is configured to generate two different second scanning signals in response to the different operating signals generated by the at least two different controlling keys after the first scanning signal is generated, the recording module is configured to record the order of the second scanning signals so as to form authenticating information for unlocking the remote control device, the authenticating module is configured to generating an unlocking signal if the authenticating information matches with a predetermined authenticating information, and the controlling module is configured to unlock the remote control device in response to the unlocked signal; wherein the processor further comprises a timer and a comparing module, the timer is configured to record a first time after the scanning module generates the first scanning signal, the comparing module is configured to compare the first time with a first predetermined time and send a first signal to the controlling module, and the controlling module controls the recording module to record the order of the different second scanning signals to form authenticating information for unlocking the remote control device if the first time is not greater than the first predetermined time.
