Wireless digital signal control motor switch

The present invention relates to a motor switch for wireless digital signal control, especially a motor switch for remotely controlling a power product such as a household appliance by Wi-Fi, and can cooperate with a mobile communication system to form a remote power supply product. remote control.

Taking the control switch of the household appliance as an example, the relay is used to control the opening or closing of the circuit; whether it is a mechanical or electronic relay, it is usually formed by an armature with controlled reciprocating displacement at one end to form an energized open state or power off. Disabled.

Traditionally, most household appliances use an attached switch for control. The user usually has to press the finger near the position of the attached switch of the appliance, or vice versa, to close it at the nearest location of the appliance. Most of the modern home appliances, including TV sets and air-conditioners, have been equipped with remote control devices. Users can control the opening or closing of these home appliances through a remote control.

Most of the remote controls of such household appliances use the Passive Infra-Red (PIR) type, and the driving distance is considerably limited, and the motor switching control of a long distance cannot be performed.

The main purpose of this creation is to provide a wireless digital signal control motor switch, especially for remote switch control of a motor switch such as a household appliance through Wi-Fi.

Another object of the present invention is to provide a wireless digital signal control motor switch capable of remotely controlling such a motor switch through an existing mobile communication system.

To achieve the above objective, the present invention comprises a Wi-Fi radio frequency module, the Wi-Fi radio frequency module is connected to a control module, and a relay module is connected by the control module; the Wi-Fi The wireless RF module receives the wireless RF signal sent by the mobile communication device by Wi-Fi; the control module includes at least a central processing unit, and the central processing unit forms a communication protocol interface with the mobile communication device for reading wireless The central processing unit is connected to a wireless communication module; the relay module includes at least one relay, one end of which is connected to the input power terminal, and the other end is externally controlled; according to the above Wi-Fi radio frequency After receiving the wireless RF signal from the mobile communication device, such as a smart phone, tablet, or personal computer, the module sends the command to the control module for processing by the central processing unit, and then sent to the relay module to control the opening of the relay. Or off to turn on the power product to be controlled or turn it off.

The controlled end of the above relay module is a power product end such as a home appliance.

In a possible embodiment, the central processing unit is programmable in accordance with product characteristics of different manufacturers.

The controlled terminal can further transmit the remote remote control code to control the power product through the wireless remote control output.

The novelty and other features of the present invention will be apparent from the following detailed description of the preferred embodiments.

As shown in FIG. 1 , in the illustrated embodiment, at least one Wi-Fi radio frequency module 10 is provided in the present invention, and the Wi-Fi radio frequency module 10 is connected to a control module 20, and The control module 20 is connected to a relay module 30.

The Wi-Fi radio frequency module 10 can receive a mobile communication device such as a smart phone 40 or a tablet 50 in a Wi-Fi (Wireless Fidelity) manner by using a preset radio frequency device. Or a radio frequency signal sent by the personal computer 60.

The control module 20 includes at least a central processing unit 21 and is preferably coupled to a voltage and loop monitoring device 22. The central processing unit 21 can communicate with an operating system such as Linnex (Linux) or Android (Android) and related micro-applications, such as read-only memory (ROM) and random access memory (RAM). And other peripheral integrated memory and computing functions, and the communication protocol interface decoding and transcoding control of the wireless RF signal transmission control data of the mobile communication device, such as the smart phone 40 and the tablet computer 50. The central processing unit 21 and the Wi-Fi radio frequency module 10 are configured by a wireless communication module (Wi-Fi chips).

In order to meet the characteristics of electrical products of different manufacturers, the control module 20 including the central processing unit 21 described above is preferably a progarammable controller, and can receive control from mobile communication devices such as smart phones 40 and tablets 50. Command data, transcoding to send the relevant wireless remote control output control band signals of different manufacturers' electrical appliances to remotely control the connected electrical products.

The relay module 30 includes at least one relay 31, and is preferably connected to a driving circuit 32. One end of the relay 31 is connected to the control input power terminal 33 (such as a household AC power source), and the other end is externally received by the control terminal 34. The control terminal 34 can be various household appliances 35, such as the illustrated home appliance to the home appliance five, including various household appliances such as air conditioners, televisions, and lamps.

The controlled terminal 34 can further be configured to control the infrared (IR) input control code or the radio frequency (RF, Radio Frequency) control band signal.

After receiving the wireless RF signal from the mobile communication device, such as the smart phone 40, the tablet computer 50, or the personal computer 60, the Wi-Fi radio frequency module 10 sends the command to the control module 20 for central processing. The unit 21 performs processing, and then controls the opening or closing of the relay 31 by the relay module 30 for opening the power product to be controlled, such as a home appliance, or turning off the power product, or transcoding and transmitting the related wireless of different manufacturers' electrical appliances. The remote control output controls the band signal to remotely control the connected electrical product.

The creation thus provides a Wi-Fi controlled motor switch for remote control of such motor switches via existing mobile communication systems, which are not only remote control of a fixed point to another fixed point, but can be carried out with a mobile communication system. For remote control, for example, even during the period of going abroad, users can still control remote power products, such as home appliances. This creation has a high degree of industrial use and can fully comply with the new type. The patent requirements are undoubted.
