Description

[0001] The present invention relates to a system and method for providing sensor information using a home network,

The present invention relates to a sensor information providing system using a home network and a method thereof, and more particularly, to a sensor information providing system using a home network for providing information on various sensors installed in a home to devices connected to a home network based on DLNA / An information providing system and a method thereof.

The home network system can be divided into home automation for controlling home devices and home entertainment for sharing media data between multimedia devices according to purposes.

Home automation technology is a technology that can control a home appliance such as a lamp, a door, a video image taking apparatus outside the home, a cooling and heating apparatus, etc. through a wall pad or a remote controller or a switch. With the recent development of sensor technology, home automation automatically detects the change of the home device and the surrounding environment by connecting the sensor (activity sensor, gas sensor, fire sensor, etc.) to the home device to configure the sensor network, It is evolving into an intelligent home automation technology that can control itself.

On the other hand, home entertainment technology is a technology for freely sharing media data among multimedia devices by connecting multimedia devices such as television, audio, PC, PMP, camera, camcorder, and electronic frame to one network at home.

The DLNA system adopts UPnP (Universal Plug & Play) which enables command and control between network devices independently of a specific operating system, programming language, and media. In the UPnP AV specification, four services are defined to support content sharing among multimedia devices. The four services are CDS (Content Directory Service), Connection Management Service, Rendering Control Service, and AV Transport Service.

As such, the home network system is being divided into home automation technology and home entertainment radios. And home automation technology is developing with intelligent home automation technology combined with sensor network technology. As the home network system is developed in two different directions, compatibility problems between these two technologies are being raised. Efforts are being made to solve such compatibility problems.

In particular, the monitoring of various sensors installed in the home is possible only in the dedicated device of the wireless sensor network, and it is impossible to monitor it in the home entertainment device. Therefore, when a user views a multimedia content such as a movie or music, the user is immersed in the content being watched, and the perception of the surrounding situation is reduced. While the user concentrates on the multimedia contents, even if a crime such as an accident such as a fire or a gas leak occurs or a home invasion occurs, the user can not recognize it and can be in great danger.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the related art, and it is an object of the present invention to provide devices connected to a home network based on DLNA / UPnP standards, And a method of providing the sensor information using the home network.

The gateway stores sensor unique information of the predetermined one or more sensors and processing priority information for the sensor unique information, compares sensor unique information included in the sensing signal with predetermined sensor unique information, The processing priority of the unique information is checked and the priority of the received detection signal is determined.

Wherein the gateway determines whether a sensing signal transmitted by the at least one sensor is received and determines whether the sensing signal is received if the sensing signal is not received, To the at least one digital device.

The gateway multicasts an SSDP message including status information on the detection signal to at least one digital device as soon as the detection signal has a higher processing priority.

The gateway updates a state value corresponding to the detection signal when the detected priority of the sensed signal is set to a low priority.

According to another aspect of the present invention, there is provided a method of providing sensor information using a home network, the method comprising: setting unique information about at least one sensor installed outside the home and a sensing signal processing priority corresponding to the unique information; Determining whether a sensing signal transmitted from at least one sensor is received; If it is determined that the sensing signal is received, determining whether the received sensing signal has a higher processing priority; And generating a SSDP message including status information on the detection signal, and multicasting the SSDP message to at least one or more digital devices, if it is determined that the processing priority is high, And updating the state value corresponding to the received detection signal if it is determined that the received signal is a signal.

Determining whether the sensing signal transmitted from the at least one sensor is received, and determining a set transmission period of the stored state value when the sensing signal is not received.

In the step of determining whether the priority is high, the determination of the processing priority is made by comparing the sensor unique information transmitted together with the sensing signal to the stored sensor unique information, and setting the processing priority of the matching sensor unique information to be high .

If it is determined that the transmission period is the set transmission period, the SSDP message including the previously stored state value is generated and multicasted to the at least one digital device, It is determined whether a sensing signal transmitted from at least one sensor is received. ,

1 is a diagram illustrating a configuration of a sensor information providing system using a home network according to an embodiment of the present invention.

Referring to FIG. 1, a sensor information providing system using a home network according to an exemplary embodiment of the present invention includes at least one sensor 100, 100-1, .., 100-N, a gateway 200, May be configured as devices 300, 300-1, ..., 300-N.

The at least one sensor 100-1, 100-1, ..., 100-N may be installed in the outdoor or indoor, or may be installed to detect various situations at the boundary between the indoor and the outdoor. It can be composed of various sensors. For example, the at least one sensor 100, 100-1, .., 100-N may be a fire sensor, a gas leakage sensor, an intrusion sensor, a temperature sensor, a humidity sensor, or the like.

Of course, the sensors included in the at least one sensor 100 are not limited to the above-described types, and may include a plurality of sensors for detecting the same situation.

The at least one sensor 100, 100-1, .., 100-N transmits sensing signals S1, S2, and S3 to the gateway 200 when detecting a situation according to the purpose of installation, At this time, the sensing signal includes sensor unique information and situation information (sensing information) capable of identifying the sensor.

For example, if the at least one sensor 100, 100-1, .., 100-N is a kitchen fire detection sensor and detects that a fire has occurred, the kitchen fire detection sensor may cause a fire in the kitchen Transmits the status information and the sensor unique information thereof to the gateway 200.

At this time, the at least one sensor 100, 100-1, .., 100-N may set various conditions for transmitting a sensing signal.

For example, a sensor for detecting an urgent situation, such as an intrusion from the outside or the occurrence of a fire or a gas leakage, is set to transmit a detection signal to the gateway 200 immediately upon detection, May be configured to transmit a detection signal to the gateway 200 at regular intervals.

The at least one sensor 100 may communicate with the gateway 200 through a short distance communication such as Zigbee, WiFi, Bluetooth, or a wired LAN. That is, it should be understood that both wired and wireless communication is possible.

The gateway 200 receives a sensing signal transmitted from the at least one sensor 100, 100-1, .., 100-N and determines a processing priority based on sensor unique information included in the sensing signal And transmits the SSDP message including the status information included in the detection signal to at least one of the digital devices 300, 300-1,..., 300-N if the determined processing priority is high. Here, the gateway 200 and at least one of the digital devices 300, 300-1,..., 300-N have the same fixed IP address and port number.

At this time, the gateway 200 may store sensor unique information and processing priority information for at least one sensor 100, 100-1, .., 100-N connected thereto. Accordingly, the gateway 200 can determine the processing priority by checking the sensor unique information.

Meanwhile, the gateway 200 receives the sensing signals transmitted from the at least one sensor 100, 100-1, .., 100-N, If the determined processing priority is low, the status value is updated based on the status information included in the detection signal.

The specific configuration and function of the gateway 200 will be described later with reference to FIG.

The at least one digital device 300, 300-1,..., 300-N receives the SSDP message transmitted from the gateway 200, analyzes the received SSDP message to obtain status information, Inform the outside of the situation information.

At this time, at least one of the at least one digital device 300, 300-1, .., 300-N may be configured to process the SSDP message when receiving the SSDP message.

On the other hand, a digital device not configured to process an SSDP message can ignore the corresponding SSDP message.

For example, among the at least one digital device 300, 300-1, ..., and 300-N, the digital device set to process the SSDP message includes a media player, a media renderer, (Media Server), and the like. Also, the digital devices 300, 300-1,..., 300-N may include various digital media players such as a smart phone, IPTV, and the like.

At this time, the media player or the media renderer may be configured to stop the music, to sound a warning alarm, or to display the status information when receiving the SSDP message, and the media server may transmit the emergency content to the clients instead of the content being transmitted Can be set.

Hereinafter, the detailed configuration of the gateway according to the present invention shown in FIG. 1 and its detailed operation will be described with reference to FIG.

2 is a detailed block diagram of the gateway shown in FIG.

Referring to FIG. 2, the gateway 200 includes a first communication unit 210, a second communication unit 230, a storage unit 250, and a control unit 270.

It will be apparent to those skilled in the art that the configuration of the gateway 200 is necessary for assisting the understanding of the present invention, and that the gateway may have more components than those of the gateway 200.

The first communication unit 210 is configured to communicate with at least one sensor 100 and the second communication unit 230 is configured to communicate with at least one digital device 300.

The first and second communication units 210 and 230 include at least one sensor 100, 100-1, .., 100-N and at least one digital device 300, 300-1, .., 300 -N) with a wired communication method or a wireless communication method, and any method known in the art may be used for each communication method. Therefore, the detailed description of the operations of the first and second communication units 210 and 230 will be omitted.

The storage unit 250 stores processing priority information corresponding to sensor unique information and sensor unique information. For example, an emergency situation such as an intrusion from outside, a fire or a gas leak can be set to a high priority for processing, and a general priority (such as a change in temperature or humidity) can be set to a low priority.

In addition, the storage unit 250 may store transmission period values of sensor information and sensing information of at least one sensor 100, 100-1, .., 100-N.

In this case, the priority of the processing according to the situation can be variously set by the user or the developer, and it is used to judge whether the occurrence of the situation is immediately notified to the user or not.

In addition, the sensor unique information may be used by the gateway 200 to determine the processing priority, and the transmission period of the sensing information may be used as a period for transmitting the general situation.

When the control unit 270 receives the sensing signals sensed by the various sensors 100, 100-1, .., 100-N through the first communication unit 210, Information on the sensor-specific information stored in the storage unit 250 and the corresponding processing priority information, and when it is determined that the processing priority of the corresponding sensing signal is high, the SSDP message including the status information included in the sensing signal is generated Multicast to at least one digital device 300, 300-1, ..., 300-N through the second communication unit 230. [

Meanwhile, the controller 270 compares the sensor unique information included in the sensing signal received through the first communication unit 210 with the sensor unique information stored in the storage unit 250 and the corresponding processing priority information, If it is determined that the priority is low, the status value of the previous detection signal is updated based on the status information included in the detection signal. Here, the updated status value is transmitted to at least one digital device 300, 300-1,..., 300-N in the SSDP message every set transmission period.

Meanwhile, the SSDP message generated from the controller 270 may be configured as shown in Table 1 below.

The SSDP message according to the present invention as shown in Table 1 includes an item (HOST) for setting an IP address and a port, and the IP address and port described above can be variously set as an example. Once set, it is used fixedly.

In addition, the SSDP message includes an item 'NTS' for indicating message status information and an item 'EVENT' for indicating status information according to a detection signal.

At this time, if the processing priority of the sensor inherent number included in the sensing signal is high, it is indicated as 'alarm' in the 'NTS' item to indicate that it is transmitted according to the emergency situation, 'NTS' item can be marked 'null' in order to inform that it is transmitted according to the general situation when the processing priority is low.

In the 'EVENT' field of the SSDP message, status information according to the detection signal is displayed. At this time, the situation information may be in the form of location information and status value, and may be in the form of (kitchen; fire occurrence), (entrance door; intrusion detection), (indoor; Here, items other than "NTS" and "EVENT" are general configurations of the SSDP message, and therefore, detailed description thereof will be omitted.

Based on the status information, at least one of the digital devices 300, 300-1,..., 300-N may sound a warning alarm, display status information, or transmit emergency content to clients.

Hereinafter, a method of providing sensor information using a home network according to the present invention corresponding to the operation of the sensor information providing system using the home network according to the present invention will be described step by step with reference to FIG.

3 is a flowchart illustrating a method of providing sensor information using a home network according to the present invention.

First, processing priority information of the sensing information corresponding to the sensor unique number and the sensor unique number is set based on the situation to be monitored (S310). The unique number and processing priority information of the sensor set in step S310 are stored in the storage unit 250 of the gateway 200. [

At this time, the emergency priority such as intrusion, fire, or gas leakage from the outside is set to a high priority, and the processing priority is set low in a general situation (general situation) such as a change in temperature or humidity.

After setting the unique number and the processing priority information of the sensor as described above (S310), the gateway 200 receives the sensing signal provided from at least one sensor 100, 100-1, .., 100-N (S320).

As a result of the determination, if it is determined that the detection signal is not received from at least one of the sensors 100, 100-1, .., 100-N (S320-No) (S320-Yes), it is determined whether the processing priority of the received sensing signal is a sensing signal of a sensor having a high priority (S330). That is, it is determined whether the received sensing signal is a sensing signal for an emergency situation.

At this time, the determination of the processing priority can be made by comparing the sensor unique information transmitted together with the sensing signal to the stored sensor unique information, and checking the predetermined processing priority information for the matching sensor unique information.

If it is determined that the transmission period is the set transmission period in step S350 (Yes in S350), the SSDP message is received from the various sensors stored in the storage unit and generates an SSDP message including the updated status value S360), and multicasts them to various digital devices 300, 300-1, ..., 300-N (S370)

However, if it is determined in step S350 that the transmission period is not the set transmission period (S350-No), the state value for the sensing signal provided from the at least one sensor 100, 100-1, .., 100- To be updated continuously.

If the SSDP message is determined to be the transmission period set in step S350, the SSDP message includes information indicating that the current message corresponds to a general situation, .

If it is determined in step S330 that the sensed sensing information has been set to a high priority (S330-Yes), that is, if the sensed sensing information is sensing information for notifying an emergency, the SSDP message (S360), and multicasts the generated SSDP message to at least one or more digital devices (S370).

However, if it is determined in step S330 that the processing priority of the sensed sensing information is low (S330-No), that is, if the sensed sensing information is not the sensing information for notifying the emergency, After updating the value (S340), the set transmission period is determined (S350).

In this case, when the SSDP message is determined to have a high processing priority, the SSDP message includes information indicating that the current message corresponds to an emergency situation and status information included in the detection signal.

Meanwhile, since it is determined that the sensor information providing method using the home network according to the present invention is a set transmission period or the processing priority is high, at least one digital device receiving the SSDP message transmitted is included in the received SSDP message And performs a notification operation based on the analysis result (S380). Here, the notification operation may be an alarm occurrence, a text message output, or the like.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. And various modifications, alterations, and changes may be made without departing from the spirit and scope of the invention.
