The invention provides a data transmission method for a commercial power supply wireless control device, in particular to a utility power supply wireless control device, after confirming a new event of the USB device, confirming the interface type of the USB device and finding a corresponding service, the notification can be notified. The portable electronic device allows it to directly manipulate the USB device remotely for the purpose of improving the usability.

According to the high development of modern electronic technology, all kinds of electronic products have been spread all over the society. Among them, portable electronic devices with smart phones or tablets are the largest. The general public can bring considerable convenience to people through the use of the portable electronic device for entertainment, work or shopping.

The portable electronic device has many different functions due to the use requirements and the convenience of carrying, so that many functions are removed or weakened (such as storage capacity reduction and button removal) to achieve lightness and shortness. The USB device can be plugged into the portable electronic device for different functions, but since the user mostly carries the portable electronic device and moves between different places, it is inconvenient for the user to carry various USB devices. Device, so in this case, the portable electronic device cannot use the functions of different kinds of USB devices.

In addition, because of the portable electronic device of a smart phone or tablet, Beginning to use is a different function from the computer, but gradually with the expansion of the function of the smart phone or tablet itself, more and more functions that the original computer has have been implemented in the smart phone or On a tablet (such as sending and receiving EMAIL, online shopping, etc.), in this case, the user needs a smart phone or tablet with more functions to facilitate the use, such as connecting printer printing or large-capacity file storage to External hard disk, etc., even control the network camera for photography or speaker playback, but because some of the above USB devices cannot be plugged into the smart phone or tablet through the cable, and some are directly placed on the fixed Position and hardly move, so how to make the portable electronic device of smart phone or tablet and various USB devices to control the USB device to increase the function of the portable electronic device, this is the inventor and engaged The goal of this industry is to improve.

The main purpose of the present invention is that after the mains-powered wireless control device confirms that there are unprocessed, USB device events and new events of the USB device, each interface type of the USB device is obtained and the USB function flag is updated, and the new device is updated. By updating the system service event to find the service registry to obtain the corresponding service, the service that is enabled and enabled on the USB device can be executed and the portable electronic device can be notified, thereby allowing the portable electronic device to directly manipulate the USB device remotely. The portable electronic device can print, store data, play music, photograph or take photos, so as to improve the convenience of use.

The secondary object of the present invention is that the processing action of updating the USB function flag is to change the corresponding bit value in each interface type of the corresponding USB device, thereby achieving the effect of labeling.

Another object of the present invention is that the utility power supply wireless control device can benefit The wireless transceiver is connected to the cloud server, and the cloud server is connected to the portable electronic device, and the commercial power supply wireless control device notifies the portable electronic device of the services enabled by the USB device via the cloud server, thereby enabling the portable device When the electronic device moves away from the position of the commercial power supply wireless control device, it can still be connected to each other for remote control of the USB device, so as to achieve the purpose of improving the scope of use and convenience.

Please refer to the second and seventh figures. As can be clearly seen from the figure, the USB device 3 can also be an imaging device 32 (such as a camera, a network camera or a camera), and the camera is determined on the system single chip 22. The device 32 has services (such as Network audio playback service, AirPlay, Digital Living Network Alliance (DLNA), Camera Steaming Service, or Sound/ After the video streaming service (A/V steaming service), the portable electronic device 4 can control the camera device 32 to capture a photo or take a video through the application interface (API), and the camera device 32 can Take a movie or photo to watch, modify or delete.

Please refer to the second, seventh, and eighth diagrams. The imaging device 32 is used as an embodiment. When the imaging device 32 is plugged into the commercial power supply wireless control device, the processing flow during use includes:

(700) begins.

(701) Query the hardware specifications of the image pickup device 32.

(702) Query the image format of the image pickup device 32.

(703) Query the image format of the portable electronic device 4.

(704) Establishing an image processing chain to convert the original image format into an image format corresponding to the portable electronic device 4.

(705) End and leave.

It can be known from the above steps that after the start, the hardware specifications of the camera device 32 are first queried, and then the image format (picture or video) of the camera device 32 is queried, and then the image format of the portable electronic device 4 is queried, and then the image is created. The processing chain, the image processing chain refers to the processing of the original image into the format required by the portable electronic device 4 (such as image size, hue, resolution, compression encoding format of motion image and sound, grid rate, data transmission) Rate, etc.), then transfer.

Referring to the ninth figure, it can be clearly seen from the figure that the image processing chain can further adjust the specification of the image output according to the condition of the network transmission. The processing flow of the image processing chain includes:

(800) begins.

(801) Query whether the network transmission status changes the video output format. If yes, proceed to step (802), and if no, proceed to step (803).

(802) Change the image output format.

(803) End and leave.

The above query network transmission status can be judged according to the rate of consumption of the queue. Decide whether to change the format of the image output, and since many network streaming technologies are connected to the TCP transmission, the image processing chain can calculate a reasonable image format according to the change of the TCP transmission and is compatible with RTSP, HTTP, etc. Mainstream network agreement.

Referring to the second and tenth views, it can be clearly seen from the figure that the USB device 3 can be a speaker device 33 (such as an audio or a speaker), and then the speaker device 33 can be judged on the system single chip 22. With the services (such as Network audio playback service, AirPlay, and Digital Living Network Alliance (DLNA)), the portable electronic device 4 can be used for the aforementioned applications. The program interface (API) adjusts the parameters such as the volume or the high and low sound of the speaker device 33, or plays the music file or the film sound through the speaker device 33.

Therefore, the present invention is directed to a data transmission method for a mains supply wireless control device, and allows the mains supply wireless control device to confirm that there is an unprocessed USB device addition event, obtain each interface type of the USB device, and update the USB function.
