Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The invention provides an interconnection device for 3C integration, which enables various devices in a digital home to be interconnected and multiplexed, and uses a wireless network to reduce wiring problems.

The invention utilizes the wireless network and integrates multiple protocol conversion technologies, so that various devices in the digital home can be interconnected and multiplexed.

Fig. 1 is a system deployment diagram of the present invention.

As shown in FIG. 1 , using the interconnection device of the present invention can make various devices in a digital home work together. In the digital home, the interconnected devices are the center, similar to wireless routers, making a star network formed among various devices. Assuming that all devices that need to be interconnected have built-in or pluggable dedicated network cards for data transmission, then each device has a unique identity, which is registered in the interconnection device. In this way, through the interconnection of devices, data streams between multiple protocols can be converted, and devices with different interfaces can be connected to the ear.

For example, a telephone set and a TV stereo work together as a videophone. When a call comes in from the telephone set, press a switch button to apply for a connection to the interconnected device, and the interconnected device selects a playback terminal for it according to the preset settings. That is, the image and sound are played on the LCD TV in the hall, and the image and sound are transmitted back to the computer through the camera and microphone, and then sent to the telephone network. For another example, movies on the computer can be played on the TV, and the air conditioner can be controlled through the interaction of voice and voice robot, which truly achieves 3C integration.

Fig. 2 is a functional block diagram of the present invention.

As shown in Figure 2, the interconnection device includes a signal transmission and reception module, a transmission control module, a device management module, a protocol conversion module, and an interconnection control module. The hierarchical relationship of each module is shown in the figure.

The signal transmitting and receiving module is the lowest module in the interconnection device of the present invention. It is used for connecting with computers and other electrical appliances, sending and receiving bit streams, sending and receiving control signals or image and sound signals, etc. must be converted through bit streams.

The transmission control module is used to realize the network transmission control protocol, and realize TCP and UDP transmission. Network transmission will have a certain probability of sending transmission errors. At this time, a mechanism to ensure reliable transmission must be required. When transferring files, control commands, etc., errors cannot be tolerated, so the TCP protocol should be used to ensure reliable transmission. When transmitting video, audio and other data streams, some packet loss can be tolerated. At this time, the best-effort transmission but unreliable service provided by the UDP protocol can be used. The transmission control module provides these two services for this device.

The device management module is like a device manager in a computer. It is used to register various electrical equipment information, including the name of various electrical equipment, network card address, destination equipment, etc. Newly added information will be saved in the memory card of the equipment management module, and can be updated through computer-specific software. It provides services for the upper-layer earlink control module. When the earlink control module receives a request, it will query the destination address of the request through the device management module, and then convert the data and send it to the address.

The protocol conversion module is used to realize the conversion of multiple data streams in different formats, which is an important part of interconnection. At present, many devices cannot be interconnected. One of the reasons is that each follows its own protocol and there is no unified protocol. The protocol conversion module is to convert between data streams conforming to different protocols. The protocol library contains methods for converting between protocols, which can be updated by connecting to a computer.

The interconnection control module is the most important module in this interconnection device. It receives signals, finds and selects destination devices, converts data stream formats, and sends out various control and data signals. The underlying bit stream is converted into a signal by the transmitting and receiving module, and then reaches the interconnection control module after being controlled by the transmission control module. The earlink control module uses the addressing function provided by the device management module to find the network card address of the destination device and select the destination for transmission. Ground, then call the data stream conversion function provided by the protocol conversion module to convert the input data stream into the necessary output data stream, and then control the transmission of the data stream through the transmission control module, and the transmitting and receiving module modulates the upper layer data stream into a bit stream for transmission to the destination.

The interconnection device also includes a pc connection module and a pc client.

The pc connection module is a wireless communication module specially used for connecting with a computer. It is connected to the computer through the USB interface and connected with the special client software of the computer to complete the sending and receiving function.

The pc client is a special software installed on the computer, and its functions are as follows: 1. Add and manage device information, including device identification, network card address, sending destination, etc. 2. Update the protocol library of the connected device. 3. Send computer data to other devices, such as sending a movie to the large LCD TV and stereo in the hall for playback.

Fig. 3 is a flow chart of adding a new device in the present invention.

As shown in Figure 3, first, the corresponding management software must be installed on the computer. Start the ear-connected device to connect with the management software on the computer. Check the network card address information of the new device to be added, add it to the device management module of the management software, and add other relevant information, such as name, signal sending target device (multiple) and so on. At this time, the management software will order the interconnected device to send a "management application" signal to the new device. At this time, manually press the confirmation button on the new device, and the new device will send back a confirmation permission signal to the interconnected device. After the interconnected device receives the confirmation information, it writes the information of the new device, including name, network card address, destination, etc., into its memory card. A confirmation link is added to the process of adding a new device, which is to ensure the safety of the device and prevent it from being maliciously controlled by external signals.

Fig. 4 is a diagram of an example of use of the present invention.

As shown in Figure 4, this figure describes the process of connecting a DVD player to a playback terminal via an ear-connected device. First of all, you must register the information of the DVD player, LCD TV, and audio on the management software on the computer, and set the output destination of the DVD player, that is, the LCD TV and audio. Turn on the DVD player and play the movie. At this time, the DVD player will send the video and audio data through its own sending and receiving module. After the interconnected device receives the data from the DVD player, it can obtain the destination address by querying the device management module. After the data stream conversion by the protocol conversion module, the converted data stream is sent to the LCD TV and the stereo. It can be seen that through the link of interconnected devices, many devices have realized cross-protocol and multi-functional multiplexing.
