Wireless control system

This creation is related to wireless control systems; in particular, a wireless control system that converts Wi-Fi signals into wireless RF signals and optical signals.

The traditional electrical equipment is controlled by optical signals (such as infrared signals) for wireless control. In other words, the user does not need to go to the electrical equipment to control the electrical appliances, and only needs to send a light signal with a control command through a remote controller to control The electrical device is activated (eg, turned on, off).

Due to the limited emission distance and emission angle of the light, some manufacturers have developed an electronic device controlled by radio frequency (RF) signals, which is equipped with a radio frequency control unit in the electrical device, and has control through transmission. The commanded radio frequency signal is sent to the radio frequency control unit to activate the electrical device.

However, although the aforementioned design can achieve the effect of wireless control, whether it is an optical signal or an electrical device controlled by a radio frequency signal, a corresponding remote controller is required for remote control. With the development of wireless network technology, Wi-Fi has gradually become popular among families. Therefore, if the Wi-Fi signal can be used to control the aforementioned electrical equipment, the convenience of the user operation can be further improved.

In view of this, the purpose of this creation is to provide a wireless control. The system converts Wi-Fi signals into wireless RF signals and optical signals to control multiple electrical devices.

To achieve the above objective, the wireless control system provided by the present invention comprises an electronic device, a first conversion device, at least one second conversion device, and at least one electrical device. The electronic device is configured to receive a Wi-Fi signal; the first converting device is configured to receive a Wi-Fi signal sent by the electronic device, and convert the signal into a wireless RF signal, and send the second converting device to receive The wireless RF signal transmitted by the first switching device is converted into an optical signal. The electrical device includes an optical signal receiver for receiving the optical signal sent by the second converting device.

The effect of the creation is to control the electrical devices having the optical receivers by transmitting the Wi-Fi signals through the operation of the electronic device and converting the Wi-Fi signals into optical signals by the conversion device.
