Data collection method and control device thereof

The present invention relates to a data collection method and a control device thereof, and more particularly to a data collection method and a control device thereof for transmitting in a wireless local area network by wireless communication.

In the prior art, the transmission mode of files between devices is roughly classified into physical transmission and wireless network transmission. In terms of physical transmission, it is necessary to perform an operation of file access between devices through a physical storage device. For example, today's video players have a Universal Serial Bus (USB) slot that can read photos and music files from memory or hard drive to play audio and video. In addition, in terms of wireless network transmission, most of the current technical aspects are only for computers using the network file system, and only the shared file directory on a single host is linked. In other words, when the user needs to transfer files between electronic devices, whether it is physical transmission or wireless network transmission, some conditions are limited, and files cannot be collected between multiple electronic devices at the same time. Therefore, how to efficiently search and transfer files between multiple electronic devices is a subject of research.

Based on the above, the present invention provides a data collection method and a control device thereof, which use the transmission structure of the wireless communication to automatically collect audio and video files shared by various electronic devices in the wireless local area network, instead of traditionally relying on a portable hard disk or a universal The serial bus (USB) flash drive is used as a way to share files.

The above described features and advantages of the present invention will be more apparent from the following description.

1 is a functional block diagram of a control device in accordance with an embodiment of the present invention. The control device 110 is coupled to the video player 150 via a universal serial bus (USB) interface. In the wireless local area network, the control device 110 controls the wireless device. The wireless access point 160 is wirelessly connected to the electronic device 162, the electronic device 164, and the electronic device 166, and the data of the electronic devices is collected and played by the video player 150. The electronic device 162, the electronic device 164, and the electronic device 166 can be a desktop computer, a notebook computer, a smart phone, a mobile phone, a tablet computer, a personal digital assistant, and the like, and have a storage device for storing audio and video files, and the video player 150 It can be a TV device, a multi-function digital disc player or a digital music player.

The control device 110 includes a memory unit 120, a communication unit 130, and a processing module 140. The memory unit 120 can be a memory embedded in the control device 110. The communication unit 130 is a transceiver with wireless communication function, supports a wireless fidelity (WiFi) protocol, and the processing module 140 is coupled. To the memory unit 120 and the communication unit 130, which may be functional modules implemented by hardware and/or software, wherein the hardware may include a hardware device having a computing function such as a central processing unit, a chipset, a microprocessor, or the like. The combination of hardware devices, and the software can be the operating system, drivers, and so on. When the control device 110 is connected to the video player 150, the communication unit 130 and the processing module 140 will be enabled, and the search function is activated.

FIG. 2A is a flowchart of a method for collecting data according to an embodiment of the present invention, and discloses how the control device 110 collects a desired video file in the electronic device 162, the electronic device 164, and the electronic device 166 in the wireless local area network. Please refer to FIG. 1 and FIG. 2A at the same time. First, the communication unit 130 searches for an electronic device that conforms to the first network sharing protocol (step 210). For example, the first network sharing protocol may be an architecture of a Common Internet File System (CIFS). According to the search result of the communication unit 130, the processing module 140 sequentially finds the audio and video files conforming to the preset video and audio format on the data folder shared by the electronic device conforming to the first network sharing agreement (step 220), as shown in FIG. In the embodiment, it is assumed that the electronic device 162, the electronic device 164, and the electronic device 166 have the structure of the first network sharing protocol, and the processing module 140 searches for the required audio and video files on the folder shared by the electronic devices. .

Then, the processing module 140 establishes, in the memory unit 120, a corresponding list of the file names of the collected video files and the real network addresses of the specific electronic devices corresponding thereto (step 230). The video player 150 reads the memory unit 120 through the processing module 140 (step 240), and the video player 150 displays the file name of the video file that can be clicked by the user on the display screen and the corresponding specific electronic device. The device name, and then, based on the real network address of the particular electronic device provided by the corresponding list, the video player 150 plays the selected particular video file (step 250).

2B is a flow chart of a data collection method according to another embodiment of the present invention. The steps S210-S230 are the same as those shown in FIG. 2A, but in the embodiment of FIG. 2B, there is more than one type of network sharing protocol in the local area network, and the data searching method provided by the present invention can also be used for each type of network. The road sharing protocol searches separately, and similarly creates a corresponding list of the file name of the video file and the real network address of the specific electronic device corresponding thereto. The detailed steps will be described as follows, please refer to FIG. 1 and FIG. 2B at the same time.

After step S230, when there are still other network sharing protocols in the wireless local area network, that is, the determination in step S232 is YES, in the wireless local area network, the communication unit 130 continues to search for electronic devices conforming to another network sharing protocol. The device (step S234), the processing module 140 finds other video files that match the preset video format on the folder shared by the electronic devices that meet another network sharing protocol according to the search result (step S236). The processing module 140 is stored in the memory unit 120, and stores the file name of the other video file and the real network address of the other specific electronic device corresponding thereto. The above correspondence list (step S238). Then, as shown in the flowcharts S240 to S250 of FIG. 2A, the video player 150 reads the memory unit 120 through the processing module 140 (step 240), and the video player 150 presents the video and audio that can be selected by the user on the display screen. The file name of the file and the device name of the corresponding specific electronic device, and then, according to the real network address of the specific electronic device provided by the corresponding list, the video player 150 plays the selected specific video file (step 250). ).

In summary, the present invention provides a data collection method and a control device thereof, which utilizes a transmission structure of wireless communication to automatically collect audio and video files shared by various electronic devices in a wireless local area network, instead of traditionally relying on a portable hard disk. Or a universal serial bus (USB) flash drive as a way to share files. The invention only needs to preset the file sharing by using the network sharing protocol in each electronic device, so that the video player can find the video file to be played in the shared files through the control device, and expand the original video player. Efficacy, increase the convenience of use.
