The present invention relates to a home network system and an event processing method for the same, and more particularly, to a home network system having a different transmission method according to the nature of an event and an event processing method therefor.

As data communication technology has advanced, there is an increasing demand for a more efficient and convenient system by interconnecting multiple systems. The home network system is one of the most demanding systems.

The home network system is a concept developed from the existing home automation system. It is used to wire or wirelessly connect digital information appliances such as TV, audio, video, computer, refrigerator, washing machine, rice cooker, air conditioner and boiler installed in the home. It refers to a system that allows users to freely control any home appliance anytime and anywhere by connecting to a network.

By using such a home network system, users can not only get functions such as door opening, intruder detection, gas alarm, fire detection, etc., which are basically provided in the home automation system, but also upgraded forms of high quality multimedia service. Entertainment services such as online, distance education and video on demand services, information services such as personal and family information management, home shopping, e-commerce and home security Etc. may be provided with a communication service (Communication Service).

Typically, wired or wireless networking technology is used to construct such a home network system.

In this case, wired networking technology is used for power line communication (PLC) using a power line installed in a home, home phone networking alliance (HomePNA) using a telephone line installed in a home, and real-time high-speed data transmission of AV devices. Institute of Electrical and Electronics Engineers (IEEE) 1394.

Among these wired networking technologies, power line communication refers to a networking technology that provides data communication using a power line for supplying power to home appliances installed in a home.

Power line communication requires only a simple process of inserting a plug into an electrical outlet to connect a home appliance to a communication network, and is more competitive than other wired networking technologies given that power lines are already installed in almost all buildings. It is considered.

As a prior art for power line communication, Korean Laid-Open Patent No. 10-2006-0021514, an event processing method in a home network system is disclosed. The above patent discloses an event processing method occurring in slave devices in power line communication.

In the patent application, an event generated by slave devices initiates a periodic event, a status event, and an error event. Here, the periodic event refers to an event that occurs automatically every certain time, and the status event refers to an event that occurs due to a voluntary state change of a slave device while monitoring the state of the system, and an error event occurs when an error related to the operation of the slave device occurs. Say event.

When an event occurs in the slave device, a data packet including an argument describing the event situation is formed and the data packet is transmitted to the master device. In this case, the packet connects the slave device with a PCL line, which is a bus network. The load is applied to the transmission modem, the transmission unit such as RS485 and the transmission module.

In this case, when one slave device transmits a data packet for notifying an event condition to a transmission line, the transmission modem and the module of all other slave devices connected to the transmission line also identify whether the data packet is transmitted to itself. As it is activated, the transmission modem and the module are overloaded, thereby overloading the entire home network system.

The present invention is to solve the above problems, an object of the present invention is to set the generation control mode of the event occurring in the slave devices in advance, and to generate in the home network system by different transmission rules according to the generated event To provide an event processing method of a home network system to reduce the load and power consumption.

Home network system according to the present invention for achieving the above object is a communication network; In connection with the communication network, an event generation mode and an event generation control mode are set according to an event type, and the event generation mode is transmitted in the event generation mode, and the transmission rule is applied according to a setting state in the event generation control mode. A slave device for processing; And a master device interworking with the communication network, setting the event generation mode and the event generation control mode to the slave device and processing an event transmitted from the slave device.

The setting of the event type is performed by the master device in the slave device, and the event type is related to an information event that is for a simple state change of the slave device and to a state change that is not urgently required by the user and is processed. It can be set to a warning event that is about and an error event that is about a state change requiring urgent processing immediately after occurrence.

The information event may be set to be transmitted or not transmitted according to a setting to the master device when a corresponding state change occurs.

The warning event may be set to be transmitted to the master device every predetermined period until the state change ends when a corresponding state change occurs.

The error event may be set to be transmitted to the master device as soon as the corresponding state change occurs.

Event processing method of the home network system according to the present invention for achieving the above object comprises the steps of setting the event generation mode and the event generation control mode for the slave device connected to the communication network; When the event generation control mode is set and a predetermined event occurs in the slave device, if the predetermined event is an information event, determining whether to transmit the predetermined event and transmitting the predetermined event to the master device only; If the annoying predetermined event is a warning event set to periodically transmit an event file, transmitting the predetermined event to the master device at each set period; And transmitting the predetermined event to the master device immediately after the occurrence of the predetermined event if the predetermined event is an error event that is to be transmitted immediately.

Hereinafter, an embodiment of a home network system and an event processing method therefor according to the present invention will be described.

1 is a block diagram of a home network system according to an embodiment of the present invention. As shown in FIG. 1, the home network system 100 configures a network for connecting home appliances in a separate home with a wired or wireless transmission medium. This network may include physically connected but logically separate networks.

The home network system 100 according to an exemplary embodiment of the present invention is connected to a bus network 60, which is an internal communication network, and a node (unsigned) of the bus network 60, and performs a network management function. A master device 10 and a plurality of slave devices 20a, 20b, 20c connected to other nodes of the bus network 60, connected to an external communication network 70, and connected to the master device 10. It has a connected gateway 40. In addition, a user interface 30 is connected to the master device 10.

The user interface 30 may be integrally implemented in the master device 10 in the home, or may be implemented in the external communication terminal 50 connected to the external communication network 70. Here, the master device 10, the user interface 30, and the gateway 40 may be referred to as a home server.

On the other hand, the bus network 60 may be a wired medium such as a power line or a telephone line already installed in a separate line, each home, or may be a wireless-based transmission medium. That is, a power line communication (PLC) network may be adopted as a wired medium, and a wireless communication network, ZigBee, Bluetooth, RF communication, or the like may be partially or entirely.

In addition, the master device 10 performs setting and processing operations for events occurring in each slave device 20. That is, when an event occurs in each slave device 20, it sets how to respond to the event. This setting is made by the user through the master device 10 and can be modified and re-edited.

In addition, the master device 10 includes a storage device such as a nonvolatile memory that stores setting information input from a user through the user interface 30 so that a predetermined control command is executed when all events occur. The master device 10 is configured to process an event file including a condition for generating a predetermined event, a control command to be executed when the event is generated, and an identification code indicating a device for performing the control command.

On the other hand, the event is a kind of processing rule in the home network system 100 according to the state change of the device. That is, the user who purchased the first master device 10 or the slave device 20 determines which event the device generates in which operation state.

For example, in the case of the washing machine, which is one of the slave devices 20, when the washing is finished, the master device 10 may display an operation state occurring in the device such as displaying a message such as "washing end" on the television monitor, which is another device. Alternatively, it may be associated with another slave device 20, or display an operation state through the user interface 30. These events are not set at the time of manufacture of the device, but are set at the time of construction of the home network system 100 by the user who purchased the device. The event is defined by the corresponding event name, the corresponding event code, and the event processing method for the corresponding event, and these items are processed after forming one packet for transmission.

On the other hand, the home network system 100 according to an embodiment of the present invention divides and processes the generated event into two generation modes. This division is processed by the user using a user interface, and the divided configuration is set in each slave device by the master device.

The event processing mode is divided into event generation mode and event generation control mode. The event generation mode is to generate an event file for all events and transmit it to the master device 10. And the event generation control mode is to control the transmission of the event to a predetermined rule in a method selected by the user.

Afterwards, when the event processing mode is set separately, the event-specific mode is set. The event-specific division modes include an information event for notifying a simple state change of the slave device 20, a warning event requiring direct processing by the user as a simple state change of the slave device 20, and a warning event. In this case, an error event for notifying an error situation in which real time processing of the slave device 20 is required is set. Such an event classification mode may be set together in an event generation mode, and an event classification and determination may be arbitrarily performed by a user.

In this event-specific classification mode, the information event is for informing the simple state change of the slave device 20. As mentioned above, "washing end and start" in the washing machine, "cooking end and start" in the case of the microwave oven, Alternatively, the message may be a notification message for notifying a simple state value change, such as an operation termination of the slave device 20 or an operation start message for notifying the start of the operation of the set event.

And the warning event is for informing the situation of the slave device 20, for example, occurs in the slave device 20, such as "filter replacement of the air purifier", "light bulb replacement" and the like, the user's direct processing is required It can be about things that become.

Next, an error event is to inform the user of a change in the status value or an error condition that the device needs to handle urgently.These error events include the transmission of error messages about the detection status detected by security sensors and gas sensors, and these errors. It may be an event processing operation related to processing for an event. Examples of such an error event may be "operation of the security sensor", "gas leak detection of the gas sensor" and the like.

When the event-specific division mode is set, the transmission rule for each event division mode is set. Regarding the setting of the transmission rule for each event classification mode, according to an embodiment of the present invention, a different event transmission method is set for each divided event mode. The event transmission rule may be classified into whether to transmit or not, periodically performing transmission, and transmitting immediately after occurrence, and is set for each event mode.

In more detail, the information event may be set as either a transmission rule when an event occurs or a non-transmission rule, and a warning event may generate and transmit an event file until the end of a situation or when another event occurs or at a predetermined period, and an error may occur. The transmission rule may be set to send an event as soon as it occurs.

Hereinafter, an event processing method in the home network system 100 configured as described above according to an embodiment of the present invention will be described.

First, in the event generation mode, when an event occurs, the event file is immediately transmitted to the master device 10 without going through the process described below. On the other hand, when the event generation control mode is set, the process described below is performed.

2 is a flowchart illustrating an event processing method of a home network system according to an exemplary embodiment of the present invention. As shown in FIG. 2, in the event processing method according to the embodiment of the present invention, when a predetermined state change occurs in the corresponding slave device 20 (S100), the slave device 20 determines whether the current state is an event generation mode or not. It is determined whether the event generation control mode (S110). In the event generation control mode, the slave devices 20 classify the corresponding state for each event according to the set method. As described above, the state is divided into an information event, a warning event, and an error event. Each of these separated events goes through a different transmission process.

When an information event occurs, when a corresponding event occurs in the slave device 20, the slave device 20 determines whether or not to transmit the event to the master device 10. When it is determined that the slave device 20 is set to transmit, the event file is generated and then transmitted to the master device 10 through the bus network 60 (S120), and the master device 10 transmits the transmitted event file. Process the file with the specified processing method. On the other hand, if it is determined that the information event is not transmitted, the event file is updated without generating an event file. Accordingly, the event occurrence situation is not notified to the master device 10.

Explaining application examples of how to handle information events. If the contents of the set event is "washing end and start", in the case of the microwave oven, "cooking end and start", etc., the operation corresponding to this event is based on the simple operation state change of the washing machine and the microwave oven, which are slave devices 20. In this case, the event may or may not be transmitted according to the set method.

When a Warning Event Occurs When an event situation occurs in the slave device 20, the slave device 20 determines whether the event occurs. At this time, it is determined whether or not the occurrence period for the event, and generates an event file for each occurrence cycle and transmits the event file to the master device 10 via the bus network 60 (S130), the master device 10 is sent The processed event file is processed by the set processing method (S460).

Explaining an example of how to handle a warning event. When the contents of the set event are "filter purifier of air purifier" and "light bulb replacement", the operation status of the slave device 20 is periodically transmitted to the master device as an event file according to the set method.

When an error event occurs, the slave device 20 generates an event file immediately after occurrence, and transmits the event file to the master device 10 through the bus network 60 (S140). In operation S460, the master device 10 processes the transmitted event file in a set processing method. In case of such an error event, if an event that requires urgent processing due to the operation of a security sensor, a gas sensor, a fire sensor, or the like is applicable, in this case, the master device 10 is immediately notified of the occurrence of the event. To be done.

The home network system and the event processing method for the same according to the embodiment of the present invention as described above may be targeted for power line (PLC) or RS485-based communication, or ZigBee (Bluetooth), RF communication It can also be adopted in low power wireless slave devices for control and monitoring in the back.

Furthermore, in the case of near field communication, an event file is broadcast when an event occurs. Therefore, in this case, each slave device must parse and process the transport packet constituting the event file every time an event occurs, but in the case of applying the embodiment of the present invention, the event is processed by classifying and processing the event with less power consumption. Can be made.

The home network system and the event processing method using the same according to the present invention are set in advance in the event generation mode occurring in the slave devices, and after the classification of the generated event according to the event generation mode according to the nature of the event generated By applying transmission rules such as transmission blocking, transmission delay and immediate transmission, the operation load and power consumption of the transmission module and modem of the home network system can be minimized.
