Description

The method and device for controlling the Lonwork devices through UPnP}

The present invention relates to a method and apparatus for controlling a loanwork device through UPI, and more particularly, a method and device for monitoring and controlling a loanwork device through a web browser or a UPI control point without installing a separate loanwork software. It is about.

In general, home network systems in the home using Lonworks networks are widely used. However, user accessibility using PC, PDA or DTV was inconvenient, and in order to compensate for the above disadvantages, the user can control the devices in the LonWorks network using the web browser or the UPI control point in a user-friendly TCP / IP network environment. There was a need.

At present, home appliances of home networks are becoming more intelligent and advanced, and communication network technology is also developing very rapidly. Various protocols such as IEEE 1394 and LoneWock are being developed to connect home appliances in a home network, and Home Audio Video Interoperability (HAVi), Consumer Electronic Bus (CEBus), and UPnP (UPnP) Universal are supported to support these protocols. Middleware standards such as plug and play are being proposed.

Based on the LonTalk protocol, the LoneWock network, developed by Echelon, is a market standard for home automation, and is a fieldbus control network that can safely transfer control or status data between network devices.

However, although the LoneWall has technical excellence in the control network, not only devices such as sensors and actuators, but also middleware frameworks that can include all devices in the home such as PCs, PDAs or DTVs can be included in the network. The part was lacking.

Since the Rontalk protocol that constitutes the Ronwork network is a closed structure, there is a limit in developing a system using the Rontalk. In addition, the installation and management of the LoneWok network required LONEWORKS software that was expensive and not easy to use.

Thus, Microsoft introduced the UTP network as an alternative, which presents a middleware framework that provides connectivity of home network devices and support of various underlying protocols. However, due to its complex framework, UF is difficult to embed in small devices and does not satisfy the characteristics of fieldbus control networks such as real-time communication and synchronization between devices.

Looking at a method for bridging the UPI sub-network and the hobby sub-network of the prior art Korean Patent Publication No. 10-2002-0005771 and the apparatus for implementing the method, to a bridge device that makes the UPI object available to the hobby object It is about. However, the prior art had a problem that the LonWok device was not controlled through the UPnP Control Point.

In addition, looking at the home network room bridge system and control method for the home automation of the prior art Republic of Korea Patent Publication No. 10-2000-0014490, structured in the lower home network unit having the meaning of the unit room in the home for home automation, Install and manage room bridges that provide home network connectors such as IEEE1394, USB, IrDA, X-10, and LoneWock for home appliance interfaces, and support interworking between home and room appliances, allowing users to access nearby room bridges from anywhere The present invention relates to a home network room bridge system for hierarchical home automation that can check or manipulate the status of all home appliances in a home network.

However, the prior art has a problem in that it is not possible to monitor and control the loanwork device through a web browser or the UPI control point without installing a separate LonWorks software, and the Lonwork network and the UBP network cannot work together.

Accordingly, the present invention is to solve all the disadvantages and problems of the prior art as described above, by using the protocol characteristics of the Lone Walk to configure a network for controlling devices in the home, while using the open structure of the An object of the present invention is to provide a home network method and apparatus that can monitor and control a device on a loanwork network using a peer-to-peer control point through a bridge that links a loanwork network and a peer-to-peer network.

The object of the present invention is to convert the RonTalk message in the bridge when the SOAP message is generated in the UPI control point and delivered to the Lone Walk network; Requesting the setup service of the UPI Lonwalk Bridge through the UTP SSDP through the UTP SSDP; Downloading a presentation HTML file corresponding to the UPI Lonwalk bridge setting service and making a desired setting request, and transmitting the setting request to a data manager; A step in which the data manager receiving the request stops the UPI Lonwalk Bridge service and the host application and updates the configuration information, and restarts the UPI LonWall bridge service and the host application after binding the newly updated configuration information. This is accomplished by a method for controlling the loanwork device via P & P.

In addition, another object of the present invention is a UPI LoneWok bridge device consisting of a UPI LoneWok setting service that serves to select a LoneWok device and a UPP LP work point, a UP Lonwalk bridge service that handles a UPN protocol; It functions as a device in the network data manager and the LoneWok network, which is in charge of connecting the LoneWok network to the IP network, and receives the LCP commands from other LPCs through the network data manager. It is achieved by a UPI LonWork control unit consisting of a LonWock host application that delivers.

The UPI Lonwalk Bridge device uses the Lontalk protocol to control the LoneWok device and incorporates a Lontalk network communication chip to implement it. In addition, the LonWorks device has standardized network variables to communicate with other Lonwork devices, and each variable establishes a virtual communication channel through a binding method. The binding of network variables between the LonWorks device and the UPI LonWalk Bridge is possible using LonWork binding software such as LonMaker.

UF is based on Internet protocols such as IP, TCP, UDP, HTTP, XML, etc., and sends and receives control commands of each device using Simple Object Access Protocol (SOAP), and through GENA (Generic Event Notification Architecture). It conveys status information of each device. UF is called the control point for clients that send control commands and observe device status.

Details of the above object and technical configuration of the present invention and the effects thereof according to the present invention will be more clearly understood by the following detailed description with reference to the drawings showing preferred embodiments of the present invention.

1 is a block diagram showing a UPP bridge according to the present invention. Referring to FIG. 1, the UPI bridge configuration is largely divided into a UPI loanwork bridge device 100, a network data manager 110, and a loanwork host application 120.

The UPI Lonwalk bridge device 100 is again the UPI Lonework configuration service (130), which serves to select a variety of Lonwork devices, UP LP points and UPI LoneWok in charge of the UBP protocol processing It consists of a bridge service 140.

The yup n Lonwork setting service 130 is to set the virtual network variables necessary to control or monitor the LonWok device in the uP network, UPI L pointwork service, the UPP L Lon Bridge service 140 is GENA and SOAP To give and receive actual orders. That is, the device description document, the service description document, the presentation document, and the like for communication in the UTP network are generated based on the data set by the UPI LonWorks setting service 130.

The variables defined by the UPI LonWok setting service 130 may be registered in the network data manager 110, and the registered variables may be controlled and monitored by the UPI LonWall bridge service 140.

The network data manager 110 is a substantial object that is in charge of connecting the LoneWok network and the IP network. The format of the data stored in the network data manager 110 is a form in which the LPC data structure is included in the LoneWorks data structure. This means that the data required for actual device management is based on the loanwork. The network data manager 110 restricts the change of the network data to the control request unit transmitted to the UPI Lonwalk Bridge to maintain consistency between the UPI and LonWorks network data.

The loanwork host application 120 performs a function as a device in the loanwork network and has a virtual network variable for communicating with other loanwork devices. The state information of the virtual network variables managed by the loanwork host application 120 is transmitted to the network data manager 110 for interworking with the UPI network. In addition, the network data manager 110 receives a control command of the UCP network to deliver a RonTalk message to other devices of the LonWorks network.

2 is a control sequence block diagram of a loanwork network apparatus via a UPI Lonwalk bridge according to the present invention. Referring to FIG. 2, when a SOAP message is generated at the UPI control point 150, the SOAP message is converted into a rontalk message at the bridge and transferred to the ronwalk network.

The UTP control point 150 requires a UBP L service bridge setting service 130 through the UTP SSP (Simple Service Discovery Protocol). In addition, when the presentation HTML file corresponding to the UPI Lonwalk bridge setting service 130 is downloaded and a desired setting (registering or deleting a variable object) is requested, the setting request is transmitted to the data manager 110. The data manager 110 receives the request and stops the UPI and Lonwalk bridge service 140 and the host application 120 to update the configuration information. After binding the newly updated configuration information and restarts the UPI Lonwalk bridge service 140 and the host application (120). At this time, a device description document (Description XML file), a service description document (SCPD XML file), a presentation document (Presentation HTML file) and the like are newly generated using the newly updated setting information.

3 is a block diagram of an update sequence of a loanwork network device through the UPI Lonewalk Bridge according to the present invention. As shown in FIG. 3, a message flow diagram performed to link the UPI discovery function and the update function in the LonWorks network is shown. For example, if a user presses a button directly when a light is turned on / off when a change occurs in the device, the changed state is changed as if the door is opened or closed. Can be monitored using GENA.

When the state is changed in the loanwork device, an update message is generated at the loanwork node 160. When the host application 120 receives the update message and transmits the updated message to the data manager 110, the setting information registered with reference to the binding is updated with the new value carried in the update message. The value updated by the data manager 110 is automatically notified to the UPI control point 150 using UPI GENA. However, the event property of the variable corresponding to this information (the state variable of UF & P) must be set to True. If the event is a variable set to pulse, the value can be manually updated by query or action.
