Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it should be understood that the following embodiments are provided so that those skilled in the art will be able to fully understand the present invention, and that various modifications may be made without departing from the scope of the present invention. It is not.

First, although an embodiment of the present invention implements an information providing service system using an example of an art gallery, the present invention is not limited thereto. For example, guidance and information providing services for at least one of a building, a monument, or an object such as a museum and an exhibition hall are provided. Wherever the space to perform may implement the system of the present invention.

1 is an overall configuration diagram for schematically illustrating an information providing service system based on an information exchange protocol between multiple devices according to an embodiment of the present invention.

Referring to FIG. 1, an information providing protocol system based on an information exchange protocol between multiple devices according to an embodiment of the present invention may be divided into a plurality of devices 100 and an information providing server 200 providing an information providing service. For example, in the home network environment, the plurality of devices 100 may be connected to an information providing server 200 that provides device control, management, automatic configuration, and information service. have.

Here, the plurality of devices 100 are based on a standardized information exchange protocol, that is, a device architecture module 110 and information provision for performing information exchange and remote control in a specific wired / wireless network based on a standard message protocol. The application 120 is mounted. In this case, the standard message protocol is called a device architecture (DA), and a basic configuration of the device architecture module is illustrated in FIG. 2.

That is, each device 100 is equipped with a device architecture module 110, and the information providing application 120 using the device architecture API is mounted thereon. Such devices 100 may be implemented as, for example, sensor devices, information devices, home appliances, network devices, built-in devices, and the like.

The information providing application 120 mounted on each of the devices 100 performs a function of receiving the guide information data transmitted from the information providing server 200 and displaying the guide information data on the screen for the user to see.

On the other hand, after each device 100 performs the device authentication through the information providing server 200, when connected to the wired / wireless access point (Access Point, AP) 10 on the wired / wireless network, automatically It is preferable to transmit its own device information to the information providing server 200.

In addition, the information providing server 200 receives the location information periodically transmitted through the information providing application 120 mounted on each device 100 and performs a function of managing location information for each device.

In addition, the information providing server 200 receives a signal detected by the sensing means 20 installed in a predetermined position in a specific space, and after determining the position of the detected signal, through the information providing application service module 220 Search for device location information at the same location as the identified location and transmit predetermined guide information data to the information providing application 120 of the device 100 corresponding to the found device location information.

In addition, the information providing server 200 receives device information (eg, an operating system (OS), a platform, a version, etc.) from the respective devices 100, and provides a platform of each device 100. It is preferable to transmit the information providing application 120 to the respective devices 100 to be installed according to.

On the other hand, the detection means 20 is typically preferably implemented as a human body sensor or wire / wireless detection switch that can detect the human body, but is not limited to this, if any one to detect a human body to output a predetermined signal Anything is possible.

On the other hand, the specific space may be, for example, a space for performing a guide and information providing service for at least one of a building, a monument, or an object such as an art gallery, a museum, an exhibition hall, and the like.

Like the plurality of devices 100, the information providing server 200 includes a device architecture module 210 and an information providing application, that is, an information providing application service module 210. The various devices 100 and the information providing server 200 exchange device information with each other, and specific control services are utilized.

Such a device architecture (DA) is needed to solve the interworking problem between home network oriented devices such as home gateways, wall pads, TVs, and the like, and to share a home network service architecture.

That is, device architecture (DA) provides device and status information, and provides functions such as network initialization, device initialization, and topology discovery for device autoconfiguration.

It also provides functions such as firmware update, configuration, file upload / download, rollback / reboot for remote maintenance, and remote control, logging, reboot, etc. for device monitoring / control. Provide the function.

FIG. 2 is a block diagram illustrating a device architecture module applied to an embodiment of the present invention in detail. FIG. 3 is a conceptual diagram illustrating a message structure of a device architecture applied to an embodiment of the present invention.

2 and 3, basically, the information providing application 120 managing the device in the home network uses an API provided by the device architecture, and the device architecture module 110 includes the discovery manager 111 and the information. The manager 112, the advertisement manager 113, the event manager 114, the control manager 115, the file manager 116, and the maintenance manager 118 are included.

The device architecture module 110 communicates with the information providing server 200 using the message generator 117a and the message parser 117b of the message manager 117. The message generator 117a creates a standard message stream for performing a unique role of an individual manager, and the message parser 117b analyzes the received standard message stream and delivers it to the manager. Do this.

The message provides status information of the device and the network, and supports device automatic configuration through a function of network initialization, device initialization, and the like, and may have a structure as shown in FIG. 3.

Referring to FIG. 3, a message of a device architecture may consist of a header and a payload. The header may be a binary stream and the payload may be XML.

The header consists of a start signal, a source device ID, a target device ID, an operation code, and an end signal. In particular, the operation code defines various functions provided by the device architecture. .

Therefore, the device architecture module 110 basically analyzes the header when receiving the device architecture message, and delivers the payload to the management unit according to the operation code. The transaction ID in the header field is an ID shared between a specific request and a response message and is time information generated based on a request message generation time, and a response is used to generate a message. The contents of the device architecture header structure are illustratively described in detail in Table 1 below.

Device architecture functions are provided through the OP Code contained in the device architecture message header. The main functions provided through operation codes are functions for automatic device configuration and remote maintenance such as device and status information, zero configuration, remote diagnostics, and healing. Is performed.

It is desirable that these functions be implemented in an open API so that they can be utilized within a home network interworking middleware system. Examples of operation codes are shown by way of example in Table 2 below.

In the device architecture protocol, specific attribute values and functions may be provided according to the type of device. Table 3 below illustrates device types and codes. The device code can be represented as 2 Bytes in total, and the first 1 byte can be used to classify the devices in the category.

In the device architecture protocol, various error codes may be defined that may be generated during a message delivery or a specific service. Basically, error codes can be represented as 2 Bytes Hex Codes and can be broadly classified into a common error, a device specific error, and a user defined error.

The common error indicates various errors related to the device architecture protocol operation code, and may include an operation error, a transaction error, a file-related error, and the like. Specific device-related errors are errors that occur in a specific service process for each device. User-defined errors relate to specific errors associated with a particular service.

Referring back to FIG. 2, each management unit of the device architecture module 110 will be described in detail.

The discovery manager 111 searches for a specific device on the home network by using a "DEVICE_DISCOVERY_REQUEST" message and a "DEVICE_DISCOVERY_RESPONSE" message. "DEVICE_DISCOVERY_REQUEST" is a request message that can be searched under a specific condition in order to know what devices or services are currently connected to the network and what the basic information of the devices is. The payload message structure to be generated together with "DEVICE_DISCOVERY_REQUEST" can be exemplarily shown in Table 4 below.

Looking at the parameter, "DiscoveryReqType" represents a condition for discovery. That is, whether to search all devices, search by device type, search by device name or device capability, and may be described as a 16 Bytes string.

"StrTypeReq" describes the actual "DeviceID" and "DeviceName" values to search for when "DiscoveryReqType" described above is "DeviceID" or "DeviceName", and "HexTypeReq" indicates that "DiscoveryReqType" is "DeviceType" or "DeviceCapability In case of "," search "DeviceType" and "DeviceCapability" value in hexadecimal.

When "DiscoveryReqType" is "All", "StrTypeReq" and "HexTypeReq" are not described. The XML schema of the payload message structure of the above-described "DEVICE_DISCOVERY_REQUEST" can be represented as shown in FIG.

"DEVICE_DISCOVERY_RESPONSE" is a response message for "DEVICE_DISCOVERY_REQUEST". The device information corresponding to the requested search condition is generated as an XML-based payload. Tables 5 and 6 below exemplify a payload message structure of "DEVICE_DISCOVERY_RESPONSE".

Looking at the parameters, "Result" is information indicating whether or not to process the response to "DEVICE_DISCOVERY_REQUEST". When the process is successful, "Result" describes the "0000" Hex value, and when an error occurs, the error code described above can be described. have.

"DeviceList" represents basic information of a device responding to an actual request, and includes the number of devices (NumOfDevice), a device ID, a device type, a device name, and a device support function. The XML schema of the payload message structure of the above-described "DEVICE_DISCOVERY_RESPONSE" may be represented as shown in FIG.

For example, a process of device discovery will be described. First, when a service is first connected to a network or a discovery command is issued on an application, the discovery manager 111 transmits a "DEVICE_DISCOVERY_REQUEST" message. In this process, the message manager 117 generates the payload XML and the header message in the message generator 117a and broadcasts the generated message.

Then, the device 100 connected to the home network receives the message through the socket, and the message manager 117 of the device 100 analyzes the header and the payload through the message parser 117b. When the operation code of the header is "DEVICE_DISCOVERY_REQUEST", the discovery management unit 111 of the corresponding device 100 compares the received information with its own device information.

If the device 100 corresponds to the request device 100, after collecting the device information, the payload XML and the header message are generated through the message manager 117, and then the device architecture message is transmitted to the requested device or service.

Subsequently, the device 100 receiving the device architecture message through the socket analyzes the header and the payload through the message parser 117b of the message manager 117, and when the header operation code is "DEVICE_DISCOVERY_RESPONSE", the discovery manager ( 111) update the device list / information.

The advertisement manager 113 functions to inform basic state changes such as connection or ON / OFF of a device by using a "DEVICE_ADVERTISEMENT" message.

The "DEVICE_ADVERTISEMENT" message is a message that informs a device (service) in the network of its basic information through broadcasting when the device is first connected to the network, powered on or turned off.

If a device participating in a network is a device such as a gateway that interworks with several devices, it may provide information of devices in its own node at one time.

The "DEVICE_ADVERTISEMENT" message is similar to the "DEVICE_DISCOVERY_RESPONSE" message structure described above, but adds an AdType to the basic information to describe "Start" / "End" in the form of a string, indicating whether the device is currently participating or outgoing. Can be distinguished.

The "DEVICE_ADVERTISEMENT" message and schema structure are shown in Tables 7 and 8 and FIG. 6 below.

Referring to the device advertisement process as an example, when the service is first connected to the network, powered on, or terminated, the payload XML and header messages are generated by interworking with the message manager 117 through the advertisement manager 113 of the device. do.

When the generated message is broadcast, the devices connected to the network receive the message through the socket, and the message parser 117b of the message manager 117 analyzes the header and the payload. When the header operation code is "DEVICE_ ADVERTISEMENT", the information, such as a Device ID, is updated by using the information transmitted through the advertisement manager 113.

The information manager 112 (Information Manager) functions to request and receive various information for a specific device on the home network using the "DEVICE_INFO_REQUEST" message and the "DEVICE_INFO_RESPONSE" message.

"DEVICE_INFO_REQUEST" is a message used to request various information for a specific device. The payload message structure to be generated together with "DEVICE_INFO_REQUEST" can be exemplarily shown in Table 9 below.

The parameter used for "DEVICE_INFO_REQUEST" is one type of information of the requesting device (DeviceInfoReqType), and the device information type can be largely divided into three types: "BasicInfo", "FunctionList", and "DeviceProperty".

"CommonProperty", "ConfigProperty", "StatusProperty", and "DeviceSpecificProperty" sub-items of "FullDescription" and "DeviceProperty" that contain all three pieces of information are also available as information types when requesting devices, all of which are in 32-byte string format. It may be described as.

"BasicInfo" is used when requesting basic information such as device ID, type and name. "FunctionList" is to request a list of functions defined by device.

"DeviceProperty" is divided into "CommonProperty" representing general information such as device model and version, "ConfigProperty" representing environment setting information, "StatusProperty" representing the current device status, and "DeviceSpecificProperty" representing unique device-specific properties. Only necessary information for each service can be requested and received.

The XML schema of the payload message structure of the above-described "DEVICE_INFO_REQUEST" can be represented as shown in FIG.

"DEVICE_INFO_RESPONSE" is a message for responding to the corresponding information according to the type of the requested information when receiving a request for information from a specific device. The payload message structure generated together with "DEVICE_INFO_RESPONSE" is shown in Table 10 below, and the message structure for each detailed type is shown in FIG. 8.

Referring to Table 10, device information can be basically divided into three types such as "BasicInfo", "FunctionList", and "DeviceProperty". When the "FullDescription" request is received, all three pieces of information can be sent together.

In addition, "DeviceProperty" can also send information for each detailed item of "CommonProperty", "ConfigProperty", "StatusProperty", and "DeviceSpecificProperty".

"BasicInfo" is used to respond to basic information such as device ID, type, name. In particular, "BasicInfo" contains information called "DeviceCapabilityList". When a new device type combining the functions of the existing devices is available on the market, various unique functions supported by the composite device can be described through the existing device type. have. Table 11 below exemplarily shows a message structure of "BasicInfo", and FIG. 9 shows a schema structure of a "BasicInfo" message.

"FunctionList" is for device-defined function lists. Table 12 below shows a message structure of "FunctionList" by way of example. "NumOfFunction" distinguishes the categories such as the number of function lists provided for each device, "FunctionID" indicates the function ID defined for each device, and "FunctionCategory" indicates whether the function is a control function or an event function.

"InputList" is a message list input on a device basis for performing a specific function, and "OutputList" means a message list output on a device basis. The basic XML schema structure of the above-described "FunctionList" message may be represented as shown in FIG.

"DeviceProperty" may be composed of "CommonProperty" representing general information such as device model, version, etc., "ConfigProperty" representing environment setting information, "StatusProperty" representing current device status, and "DeviceSpecificProperty" representing unique device-specific properties. . Only necessary information for each service can be requested and received. Table 13 below exemplarily shows a message structure of "DeviceProperty", and FIG. 11 exemplarily shows a schema structure of "DeviceProperty".

"ConfigProperty" describes information for network configuration and firmware or software configuration of the device. In particular, in the case of device configuration, "Configuration" file name information is described so that each manufacturer can configure itself. Here, FTPURL of "DeviceConfig" is an FTP address for file management for "Configuration File" and "Apply Operation".

For example, the device information request and response process of the information management unit 112 will be described. When a specific device is selected by the service or application and requests specific information, the payload XML and header message will be generated in cooperation with the message management unit 117. do. The generated message is delivered to the target device ID, and the device receives the message through the socket.

Then, the message manager 117 of the device analyzes the header and payload, and when the header operation code is "INFORMATION_REQUEST", the information manager collects the information of its own device and cooperates with the message manager 117 to check the payload XML. Generate a header message. Then, when the message is sent to the requesting device or service, the device receiving the message analyzes the header and payload through the message manager 117. If the header operation code is "DEVICE_INFORMATION_RESPONSE", the device information is updated using the received information.

The control manager 115 controls a device or a service through various device-specific functions by using a "DEVICE_CONTROL_REQUEST" message and a "DEVICE_CONTROL_RESPONSE" message.

"DEVICE_CONTROL_REQUEST" is a request message for controlling a device or service through various device-specific functions. Function lists for each device may be variously described according to the type of the corresponding device.

Table 14 below shows a message structure of "Device Control Request" by way of example. In case of "FunctionID", total 4Bytes is composed. Upper 2Bytes is Device Type Code and Lower 2Bytes is used to distinguish Function List.

Therefore, even if only "FunctionID", it is possible to know which device and how to control. In addition, it can be informed whether the corresponding message is control information or event information through "FunctionCategory", and can be described as "Control" or "Event" through a string type. The XML schema structure of the payload message structure of "DEVICE_CONTROL_REQUEST" may be represented as shown in FIG. 12.

"DEVICE_CONTROL_RESPONSE" is a response message to the "DEVICE_CONTROL_REQUEST" message to perform various device-specific functions. The response type may vary from information indicating whether the corresponding function is normally performed to the request to various information according to the service result, and the basic message structure may be the same as "DEVICE_CONTROL_REQUEST". Table 15 below shows an example of the "DEVICE_CONTROL_RESPONSE" message structure, and the XML schema structure may be represented as shown in FIG.

Referring to the device control process of the control manager 115, for example, when a specific device is selected by a service or an application and requests control, the control manager 115 generates a payload XML and a header message in cooperation with the message manager 117. The generated message is delivered to the target DeviceID, the target device receives the message through the socket, and the message manager 117 analyzes the header and payload.

If the operation code of the header is "CONTROL_REQUEST", the control manager analyzes the received information and calls the corresponding device control module, issues a control command from the corresponding device control module, collects the necessary information in the function structure, and then the message manager 117.
