20090022151 | PACKET STRUCTURE AND PACKET TRANSMISSION METHOD OF NETWORK CONTROL PROTOCOL - A packet structure and a packet transmission method of a network control protocol. A user in the inside or outside of the house can effectively control various home appliances such as refrigerator or laundry machine or monitor operation state of the devices, over the living network such as RS-485 network, low-power RF network, and power line network so that the user can enjoy the remote control and the convenient monitoring. In addition, the packet structure for the inter-layer interface of the network control protocol can be managed. The packet structure at the application layer is generated by assigning one of an application layer protocol data unit header, a request message, a response message, and an event message, together with an application layer protocol data unit header The generated packet at the application layer is transmitted to thus interface layers of the network control protocol. Therefore, the packet structure at the application layer can be more efficiently managed and transmitted. | 01-22-2009 |
20090024726 | DEVICE FOR NETWORK SYSTEM AND METHOD OF TRANSMITTING PROFILE - The present invention relates to a device for a network system and a method of transmitting a profile in a network system. The method provides a user with convenience in remote control and monitoring operation of appliances. By this method, a user, for example, who is locating at home or out-of-home, can control the operation or monitor the operational state of various appliances such as refrigerator or laundry machine through a living network installed at home, such as RS-485 network, a low power RF network, or a power line network. The method according to the present invention further provides a user with effective network service by continuously managing and updating information on all devices constituting the network using a network profile. | 01-22-2009 |
20090024727 | NETWORK SYSTEM MANAGEMENT METHOD - A network system management method is provided. According to the method, a user inside or outside home can control or monitor the operations of appliances such as refrigerator or laundry machine through a living network such as an RS-485 network, a small output RF network, and a power line network provided inside home so that the user can perform remote control and monitor. Also, when a new device to which no address is assigned is connected in a state where a plurality of network managers are connected to the living network, only an arbitrary network manager sets and registers the address of the corresponding device and updates and manages the homenet profile suitable therefor through interface with the other network manager or a primary network manager sets and registers the address of the corresponding device and updates and manages the homenet profile suitable therefor through interface with a secondary network manager so that it is possible to effectively manage and control the devices connected to the network without redundancy error on the network to which the plurality of network managers are connected. | 01-22-2009 |
20090031177 | Method for providing download and upload service in network control system - The present invention relates to a method for providing a download and upload service using variable length packet communication in a living network control system. For example, a user located inside or outside a house controls or monitors operations or operation states of various appliances such as refrigerator or laundry machine through a living network installed at home, such as a RS-485 network, small output network, or power line network so that convenience of remote control and supervision can be provided to a user. Further, in a case where a download or upload service is executed in a living network in which various appliances connected thereto, variable length packet communication, which is capable of diving data by the buffer size of a device, and then sending and assembling the data, is used so that a download and upload service for various appliances connected through the living network can be more effectively executed. | 01-29-2009 |
20090073972 | ADDRESS MANAGEMENT METHOD AND MESSAGE TRANSMITTING AND RECEIVING METHOD IN NETWORK CONTROL SYSTEM - The present invention relates to an address management and message transmitting and receiving method in a network control system. The present invention, for example, enables a user in the inside or outside of house to control the operation or monitor the operation status of various appliances such as refrigerator, laundry machine, etc through a network such as RS-485 network, low power RF network, power line network, etc. installed at home, thus making it possible to provide the convenience of remote control and monitoring to the user. In addition, the present invention may flexibley assign and manage addresses for all the devices connected to one another through the network, and transmit and receive messages between a master and a slave, thus making it possible to control the appliances in the network control system more efficiently. | 03-19-2009 |
20090160626 | Method for Setting Home Code in Network System and Device for Network - The present invention relates to a method for setting a home code in a network system and a device for a network system. The method and device allow a user to conveniently remote control the operation of and monitor the operational state of appliances. Thanks to the method and device, a user, for example, who is locating at home or out-of-home, can control the operation or monitor the operational state of various appliances such as refrigerator or laundry machine through a living network installed at home, such as RS-485 network, a low power RF network, or a power line network. The method of setting a home code in a network system includes a first step of producing a random home code value using a random numbers generation algorithm, a second step of checking whether the random home code value is a unique code, and a third step of setting the random home code value as a home code of all devices connected to a network when it is found that the random home code value is a unique code as the result of checking, so that all the devices connected to the same network have the same home code. The present invention is very useful in ability of effectively setting and managing a unique home code in a network. | 06-25-2009 |
20090213848 | Packet Structure and Packet Transmission Method of Network Control Protocol - A packet structure and packet transmission method of a network control protocol. A user in the inside or outside of the house can effectively control various home appliances such as refrigerator or laundry machine or monitor operation state of the devices, over the network such as RS-485 network, low-power RF network, and power line network so that the user can enjoy the remote control and the convenient monitoring. In addition, the packet structure for the inter-layer interface in the network system can be managed. The packet structure at the network layer is generated by assigning one or more fields indicative of a packet start, a destination address, a source address, a packet length, a network layer control, an application layer protocol data unit, a cyclic redundancy check (CRC), and a packet end, and a field indicative of a network layer control. The generated packet structure of the network layer is transmitted to thus interface layers in a network system. Therefore, the packet structure at the network layer can be more efficiently managed and transmitted. | 08-27-2009 |
20100030913 | COMMUNICATION CONTROLLING METHOD FOR NETWORK MANAGING DEVICE - The present invention relates to a communication controlling method, and more particularly, to a communication controlling method for a network managing device that can control a speed of a network and a transmission/reception amount of packets according to a communication situation. A communication controlling method for a network managing device includes the steps of judging a speed of a connected network or a transmission/reception amount of packets, setting an increase/decrease amount of an event transmission interval of a network device according to the judgment result, and transmitting the set increase/decrease amount of the event transmission interval to the network device through the network. | 02-04-2010 |
