[Prior Art] 豕 制 制 制The development of the coffee industry] In the single court, the use of electrical appliances to form a regional network for control purposes has been achieved. H. There are dozens of communication protocols for these home area networks. For example, the SCP (Simplified Control Protocol) in the United States. LonTalk standards, Japan's echONET (Energy Conservation and Homecare Network) communication standards and European KNX communication standards, but these regional communication standards also make the home area network regional, can not be unified. In order to enable home appliances to connect to the Internet, the Universal Plug and Play (UPnP) protocol has been developed as an open, distributed protocol. The protocol group is built on some known standards such as IP, TCP, UDP, HTTP, XML, and SOAP. It allows computers to communicate in a peer-to-peer fashion, allowing multiple home appliances to form a network and supporting wireless transmission technologies. As a result, there are some technologies that combine home area networks with universal plug-and-play protocols to control home appliances via the Internet, but there are many shortcomings. For example, a bridging device of the prior art is capable of converting between ECHONET and UPnP. However, for the user, an additional bridging device is required to be installed on the home appliance, which not only causes additional expenditure for the user, but also causes inconvenience in use. In addition, the bridging device needs to include the conversion component between the ECHONET and the UPnP, so that the specifications of the electronic components on the circuit board of the bridging device, such as the CPU and the memory, are greatly improved, and even the operating system (OS) is required, so that the bridging device is Increased complexity and production costs and reduced product competitiveness. Furthermore, the bridging device described above is also only suitable for bridging between ECHONET and UPnP. If it is replaced with a home appliance having other communication protocols, such as the KNX protocol in Europe, the bridging device described above cannot be used. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a home appliance capable of achieving network control and reducing production costs without requiring the user to additionally purchase a bridge device. In order to achieve the above object, a household appliance according to the present invention comprises a

The appliance body does not have any built-in appliance communication agreement. The universal plug-and-play bridge module has a first interface unit, a second interface unit and a conversion unit. The first interface unit receives or transmits a packet in accordance with a universal plug and play protocol. The second interface unit is electrically connected to the main body. The conversion unit includes a single-wafer microprocessor and is electrically connected to the first interface unit and the second interface unit. As described above, the home appliance of the present invention comprises a universal plug-and-play bridge module, which enables the home appliance to be connected to the network and controlled, and the bridge device is purchased without the user's quota 5 201038018. In addition, the home appliance body (including the control circuit board) does not have built-in (or supports) any home appliance communication protocol (such as UPnP, ECHONET, KNX), so that the complexity and production cost of the bridge module of the present invention are greatly reduced, and This is achieved with a single-chip microcontroller (such as the 8051 chip), which in turn increases product competitiveness. [Embodiment] Hereinafter, a home appliance according to a preferred embodiment of the present invention will be described with reference to the related drawings. As shown in FIG. 1, the home appliance A1 of the preferred embodiment of the present invention includes an electric body D1 and a universal plug-and-play bridging module 1. Wherein, the home appliance body D1 does not have any home appliance communication protocol, that is, the control circuit board of the home appliance body D1 does not have any module of the home appliance communication protocol, and the above-mentioned home appliance communication protocol such as Universal Plug and Play (UPnP), ECHONET or KNX communication standard. The home appliance body D1 may be, for example, a 3C product, or an audio-visual device, or a lighting device, or a kitchen device, or other consumer electronic products (e.g., a webcam, a taster, a vacuum cleaner). The universal plug-and-play bridge module 1 includes a first interface unit 11, a conversion unit 12, and a second interface unit 13. The first interface unit 11 receives or transmits a packet in accordance with a universal plug and play protocol. Since the UPnP communication protocol is established under the TCP/IP protocol, the bridge module 1 can be connected to the Internet INT by the UPnP communication protocol and can be controlled by a control device C. The first interface unit 11 is interposed between the Internet INT and the conversion unit 12, and is configured to transmit the packet transmission 201038018 transmitted by the control device C to the conversion unit 12, and transmit the packet transmitted by the conversion unit 12 via the Internet INT. Transfer to control unit c. The first interface unit u can be, for example, a wired interface or a wireless interface, wherein the wired interface is, for example, an Ethernet Module, and the wireless interface is, for example, Wi_Fi (ieee 8〇2.lla/b/g/n). Or a wireless network module such as a Bluetooth module (Bluet〇〇thM〇dule). In addition, the first interface unit 11 may also include two or more different interface modules. The second interface unit 13 is electrically connected to the home appliance body D1. The second interface unit 13 is interposed between the home appliance body D1 and the conversion unit 12 for transmitting a control signal to the home appliance body D or transmitting the signal of the home appliance body D1 to the conversion unit 12. The second interface unit π can be, for example, an rS_232 interface, or a universal serial bus (USB) interface, or a Firewire interface (1394), or a digital/digital conversion interface (D/DConverter), or a digital/analog conversion (D/A Converter). )interface. The second interface unit 13 may be selected according to the type of the appliance body D1 to be applied. For example, when the home appliance body D1 is a digital camera, the FireWire interface may be recommended. If the home appliance body D1 is an audio-visual device, it may be recommended. The RS-232 interface or the universal serial bus (USB) interface, the second interface unit 13 may also include two or more different interface modules. The interface specifications of the first interface unit 11 and the second interface unit 13 may be based on the manufacturer. Customized and needed. The conversion unit 12 is electrically connected to the first interface unit 11 and the second interface unit 13. The conversion unit 12 includes a single-chip microcontroller, such as an 8051 wafer. The converting unit 12 can perform addressing in the universal plug and play protocol, and find tasks such as 201038018 (discovery), description, control, event notification, and presentation. . In the present embodiment, the 'conversion unit 12' includes a control element 121 and a storage element 122. The storage element 122 stores a code. Control element 121 can be, for example, a core portion within a single wafer, and storage element 22 can be a read-only memory (e.g., R〇M) within a single wafer. Of course, if the code has too much capacity, the storage element 122 can be external to the single chip, and more includes a memory (e.g., EEPR0M). Alternatively, storage element 122 can be implemented entirely using memory other than a single chip. The execution of the code in the storage element 122 by the control element 121 can at least achieve the tasks of the Universal Plug and Play protocol. First, in terms of the addressing task, it can be achieved by the control element 121 teaching the run code. When the bridge module 丨-cuts the Internet, it will first search whether there is a Dynamic Host Configuration Protocol (Dynamic H〇st C〇nflgUration Protoc〇i, DHCP) server on the network. If there is a server crying, the servo H will assign a group heart address to the bridge module ι; if no ship name is found, the network module is unmanaged, the bridge module ^ will recognize one 1 bit. Address and use the 1P address. The control element 121; the code of the line can be at least divided into a TCP/Ip part, an upnp part, and an update part. The above-mentioned operation of the address can be implemented by the control element 执行2ι executing the upnp part and the TCP/IP part, wherein the UPnP part 贝 贝 搜 及 and the IP address are given, and the TCP/IP part can be responsible for the 妒> Analysis of the corners and the operation of encapsulating information. After obtaining or giving the IP address, the conversion unit 12 performs the 201038018 discovery task. When the bridge module 1 is connected to the network, the bridge module 1 needs to inform the control device on the network that it has the services. Similarly, when the control device C is connected to the network first, the uPnP communication protocol will also let Control device C searches for the bridging module 1 present on the network. When the bridge module 1 and the control device C find each other, there will be some basic or important information transmission, such as the type or service of the bridge module 1. The discovery task of the υΡηΡ agreement is based on the Simpie Service Discovery Protocol (SSDP). The above operation can be achieved by the control element 121 Ο executing the UPnP part and the TCP/IP part of the code, wherein the UPnP part is responsible for providing the information to be exchanged with the control device C in the discovery task, and the TCP/IP department is responsible for the information. Packets are parsed or parsed from the network. After the control device C finds the bridge module, the control device c further knows the function of the device to be controlled, and the % obtains a description of the home appliance D1. The description slot contains relevant information of the manufacturer, related functions of the home appliance "D1 function, model, and/or serial number, and also includes the webpage extension of the bridge module 1 (Uniform ReSource 〇

In order to pay for: the control device c needs to first send a description slot package 'ϋ--: 21 execution code Tcp / ip part to unblock to pay - the first - poor material, the first information of this aspect is Household appliances = package U-(request). After receiving the description slot request, the control module 121 of the module control module executes the code of the upnp material to encode the second data 1 according to the universal plug-and-play protocol, and the second data of this aspect is ' The description slot of the electrical body D1. Then, the control component 121 executes the program stone P to transmit the second data after the mother is packaged and the parent interface device n is transmitted to the control device c via the Internet. After taking the description building, the control device c can transmit a control packet to send the control command to the bridge module 1. The control component 121 executes the TCP/IP portion of the code to parse the packet to obtain the "first" material, the first poor material of which is the control command. The control unit 121 executes the UPnp portion of the code to convert the first data into a control signal transmitted to the home appliance body D1 to control the home appliance body D1 to execute a corresponding service. In addition, in response to the service, the bridge module i also transmits an action-specific value to let the control device c know that the home appliance D1 has performed the service. At the same time as the home appliance body D1 performs the service, the event notification task is entered. When the power body D1 is being serviced, the environmental state is constantly changing, so that the value of the variable changes accordingly. The event notification task allows the control device C to subscribe to these variables. When the values of the variables change, the bridge 10 201038018 module 1 transmits the variables and their values to the control device C via the network. In order to achieve the above operation, the second interface unit 13 can receive the message from the home appliance body D1, and the control component 121 executes the UPnP portion of the code to convert the message into the second data and encode according to the universal plug and play protocol. The second data is the above variables and their values. The control component 121 then executes the TCP/IP portion of the code to package the encoded second data in accordance with the TCP/IP protocol and forward it to the control device C via the first interface unit 11.最后 The last task of the UPnP protocol is presented. The control device C can obtain a web page from the bridge module 1 by using the aforementioned web address (URL) to allow the user to control the home appliance body D1 and view the state of the home appliance body D1. In order to achieve the above action, the control device C needs to send a webpage request packet first, and the control component 121 executes the TCP/IP part of the code to parse the packet and obtain a first data. The first data of the aspect is a webpage request (request ). After receiving the webpage request, the control component 121 of the bridge module 1 executes the UPnP section of the φ code to encode a second data according to the universal plug and play communication protocol. The second data of this aspect is a webpage. The control component 121 then executes the TCP/IP portion of the code to package the encoded second data in accordance with the TCP/IP protocol and forward it to the control device C via the Internet interface INT by the first interface unit 11. In addition, when the home appliance body D1 is upgraded to a newer model, the bridge module 1 can also update its software corresponding to the ground to achieve a functional upgrade to provide a new function of the new model home appliance. When performing an online update, first, the control device C may first transmit the update code packet to the bridge 11 201038018. The control component 121 executes the TCP/IP portion of the code to parse the packet and obtain a first data, the first data of which is an online update. Online update data can be stored in storage element 122 or stored in other memory. Then, the control unit 121 can execute the update portion of the code to overwrite the first data to the UPnP portion of the code to complete the online update. In addition, in the present embodiment, the control device C can transmit packets through the uPnP protocol, or through the Open Services Gateway Initiative (〇SGi) platform or the Digital Living Network Alliance (Digital). The Living Netw〇rk Auiance, DLNA) platform, or the Support Windows Collection (Wind〇wsRally) platform transmits the packet to the brother; the face unit 11. The above mentioned SGi, DLNA and Windows Rally can support UPnP communication protocol. 2, the main operation flowchart of the execution of the code by the control element 121 of the present embodiment is described. Of course, this is only one of the possible implementations and does not limit the present invention. First, the bridge module 1 is powered on, connected to the network to execute the system, and 'initialized first. The bridging module 1 then performs the addressing task to obtain its own address. Then, judge whether the packet is received. If not, then the (or, 仃) discovery task is executed; if so, it is determined whether the received packet is a suffix requesting the packet 'of course' the process of determining that the packet is parsed X is taken from the first data. If it is a description file request packet, the reply description file is communicated to the control device c; if not, it is determined whether it is a control packet. If =, the control command contained in the packet is executed, and the event notification arbitrage is executed to allow the control device c to obtain the state variable in the execution of the home appliance; if it is not 201038018, the packet is determined to be a webpage request packet. If yes, the page is returned to the control device c; if not, it is determined again whether the packet is received. Since the execution process of the above process has been described in detail above, it will not be described here. It should be noted that the above-mentioned action flow is not necessarily in order. For example, it may first determine whether a control packet is received, and then determine whether to receive the description file request packet, or first determine whether a web page request packet is received, and then determine whether the description slot is received. Request a packet. Please refer to FIG. 3, which is a schematic diagram of a home network constructed by the home appliance of the preferred embodiment of the present invention. For example, two home appliances A1 and A2 are taken as an example, and of course, more household appliances can be used to form a home network. In addition, in the home network, the plurality of household appliances A and A2 are controlled by a control device C. Of course, the home appliances A1 and A2 can be controlled by the other control device through the Internet INT. The home appliance A1 has been described in detail in the above embodiment, and the home appliance A2 of the present embodiment is different from the home appliance A1, so that the conversion units 12a and 12 are also different, for example, the conversion unit 12a, 12 is stored. The description file and / or code are different. In summary, the home appliance of the present invention includes a universal plug-and-play bridging module that enables the home appliance to be connected to the network and controlled without the need for the user to purchase the bridging device. In addition, the home appliance body (including the control circuit board) does not have built-in (or supports) any home appliance communication protocol (such as UPnP, ECHONET, KNX), so the home appliance industry wants to increase the Internet access function of its home appliances, only need to install Single-chip microcontroller (such as 8051 crystal. Month) universal plug-and-play bridge module, and write different description files with different products, not only the technical threshold is reduced, but also the production cost is greatly reduced. 13 201038018 Increase the competitiveness of home appliances. The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
