## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an outlet switch socket device; in particular, to an outlet switch socket device allowing both electronic device power control and electronic device function control features.
2. Description of Related Art
Currently available remote controls for controlling the functions of various types of audio-video switch socket device mostly use Infra-Red (IR) technology to perform wireless remote control. However, due to poor penetration of IR beam and directional limit, the emitter in the IR remote control needs to be substantially aimed at the IR receiver installed in the audio-video switch socket device so as to achieve the purpose of IR remote control. Therefore, in case that it is needed to remotely control a distant IR audio-video switch socket device, the IR technology may not be able to successfully meet such a requirement. Besides, there at present also exists a type of Radio Frequency (RF) remote control, which presents better radio penetration feature without undesirable directional limits, thus very suitable for the use as the remote control function.
In general, a common remote controlled outlet switch socket device comprises a receiver, which receives a control signal emitted from some remote device. Then, the socket on the remote controlled outlet switch socket device is under the control of the control signal to be set as conducting or not; thereby, the remote controlled outlet switch socket device may control whether to supply power to the electronic device plugged to the socket, further operating the power ON/OFF of such a plugged device. However, the aforementioned remote controlled outlet switch socket device can only control whether to supply power to the electronic device, but is still unable to control operations of other functions of the electronic device.
Accordingly, it is desirable for the industry to provide an outlet switch socket device allowing both electronic device power control and electronic device function control.
SUMMARY OF THE INVENTION

As such, the outlet switch socket device according to the present invention is allowed to control not only whether to supply power to the IR electronic device but, meanwhile, various functions thereof.
The outlet switch socket device according to a preferred embodiment of the present invention is controlled by a control signal, comprising: a plug, at least one socket, at least one switch, a power converter, a communication module, a microprocessor and an IR module. Herein the plug is used to receive an alternative current (AC) power. Each of the at least one switch is respectively connected in series between each corresponding socket and the plug. The power converter is coupled to the plug and used to convert the AC power into a direct current (DC) power. The communication module is used to receive a control signal. The microprocessor is coupled to the communication module, the power converter and the at least one switch to use the DC power, controlling the enable or disable of such switches based on the control signal and transferring the control signal to the IR module. The IR module is coupled to the microprocessor and emits an IR signal to an IR electronic device based on the control signal.
In summary, the outlet switch socket device according to the present invention combines the technologies of RF wireless remote control and IR control to remotely control an IR electronic device at a distance, thus providing both the control over power supply to the IR electronic device as well as the control over various functions of the IR electronic device. In this way, the present invention is allowed to effectively eliminate the drawback that conventional remote controlled outlet switch socket device can only control the power supply to the electronic device, but is unable to control other features thereof.
