HOME SECURITY SYSTEM AND METHOD USING IEEE 1451 STANDARD}

The present invention relates to a home security system and method, and more particularly, to a home security system and method to which the IEEE 1451 standard for coping with home disaster prevention, fire prevention, and crime prevention is applied.

Recently, home networks and home automation fields have been attracting attention for the connection and utilization of various electric / electronic devices and communication devices in homes and offices due to the wide spread of the Internet and the development of communication technologies.

The development of such communication technology is moving toward the big flow of voice data integration, wired / wireless integration, and broadcasting communication convergence.When NGN called the next generation network is completed, it is combined with the same communication service or communication regardless of terminal type or network in a single packet network. It is expected to be able to receive a converged service.

In addition, the home networking technology that all information devices are intelligent and connected to the network is expected to be the leading player in the development of information and communication technology in the future. Furthermore, the advent of the ubiquitous era with the advent of IPv6, which can be connected to any terminal device anytime, anywhere, is a good example of the importance and potential of sensor networking. Here, ubiquitous is a Latin word that exists anytime, anywhere, and is an abbreviation of ubiquitous computing, and refers to an environment / space which is serviced while being on an online network using anytime, anywhere.

At present, there are various networking technologies such as Ethernet, power line communication, home RF, IEEE 1394, and Bluetooth, but there are no technologies defined as home networking standards. Home networking allows users to connect to the outside via the Internet using xDSL, HFC, FTTH, etc., which are used as internet access technologies. Currently, xDSL modems and cable modems are equipped with local storage in the future. It will also develop into a home gateway that plays a pivotal role in the home network that controls and manages various digital devices in the home.

However, most home networking technologies are used to connect A / V devices, information terminals, etc., and thus are not suitable for sensors that will connect all devices in the user's home like a spider web in the future. In other words, unlike the information terminal equipment, the sensor is more likely to be connected at all times than required, and the data transmission rate is also several tens of Kbps, and does not need to be connected at tens of Mbps to several hundred Mbps as in IEEE 1394. You should be able to calibrate by changing the sensor parameters according to However, current technologies commonly used in home networking such as IEEE 1394 do not consider those characteristics required for sensor networking.

Accordingly, the present invention has been made to solve the above problems, using the IEEE 1451 standard designed to be suitable for sensor networking, the disaster prevention, fire prevention, and crime prevention in the home from the outside while providing data transmitted from the sensor to the Internet terminal It is an object of the present invention to provide a home security system and method to which the IEEE 1451 standard for dealing with the above is applied.

In addition, according to the present invention, the home security method for coping with disaster prevention, fire prevention, crime prevention, etc. in the home is applied according to the IEEE 1451 standard, and according to the IEEE 1451 standard, the temperature, humidity, gas, intrusion state, etc. Detecting; The home gateway receives the data detected by the sensor according to the IEEE 1451 standard and compares the received data with preset reference data, and transmits the detected data to the user's Internet terminal through the Internet network when it is determined that there is an error. step; And after the user connects to the home gateway and checks the state of the sensor, remotely controlling a home security device such as a temperature controller, a humidity controller, a gas circuit breaker, a fire extinguisher, and an alarm generator in the home.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

1 is a network configuration diagram of a home security system to which the IEEE 1451 standard according to the present invention is applied, connected to a home gateway 130, an NCAP 140, a sensor 150, and a controller 160 and an internet network 120. Internet terminal 110 is configured. Through such a configuration, the user can monitor the home from outside and take necessary measures while coping with disaster prevention, fire prevention, or crime prevention.

The sensor 150 conforms to the IEEE 1451 standard and includes a Smart Transducer Interface Module (STIM), which is installed at a predetermined location in the home to sense temperature, humidity, gas, and intrusion conditions. Here, the IEEE 1451 standard is an open way of coupling sensors to a network bus, making it easier to network the sensors so they can prove themselves and work with a variety of industrial buses such as Ethernet, Profibus, DeviceNet, etc. . The sensor 150 may be installed in a wireless or wired form.

The controller 160 is an actuator such as a switch, a relay, a variable resistor, a variable capacitor, an electric motor, and the like. You can control and take the necessary action.

The home gateway 130 has an IEEE 1451 interface and is interlocked with the sensor 150 to process data received from the sensor 150 while exchanging data with each other through communication according to the IEEE 1451 standard. To send. In this case, the data received from the sensor 150 may be processed and transmitted in the form of an e-mail. In addition, a web server may be provided to provide information in a web service environment.

The NCAP 140 serves as an interface between the sensor 150 or the controller 160 and the home gateway 130 according to the IEEE 1451 standard, that is, an intermediate transmission path. Thus, by using the NCAP 140, all sensors can be designed to have a standard interface.

The Internet terminal 110 is a PC, PDA, notebook, mobile phone, etc. that can be connected to the Internet network 120 in a wired or wireless form, after the user connects to the home gateway 130 using the Internet terminal 110, Monitoring and control of the sensor 150 or remote control of the home security device 170 through the controller 160 may take necessary measures. In this case, the user may access the home gateway 130 through the Internet terminal 110 to remotely control the sensor by modifying a parameter value of a transducer electronic data sheet (TEDS).

The Internet connection line may be copper, cable, Ethernet, optical cable, etc. according to the connection medium. In order to access the Internet network 120, the Internet such as an xDSL modem, a cable modem, a switching hub (S / H), a photoelectric conversion device, etc. A connection device is necessary.

Referring to FIG. 2, a sensor installed in the home and complying with the IEEE 1451 standard detects temperature, humidity, gas, and intrusion conditions, and initiates communication with a home gateway connected to the home communication network according to the IEEE 1451 standard (S210, S220). ).

The home gateway receives the data detected by the sensor and compares the received data with the preset reference data. If the gas is exposed or the trace of intrusion is found to be abnormal data, the home gateway uses an e-mail or the like through the Internet. Inform the user by transmitting to the Internet terminal (S230, S240).

Subsequently, the user accesses the home gateway through his or her internet terminal, logs in, and checks the installed sensor status. If normal, the user logs out and exits. In addition, remote control of home security equipment such as an alarm generator is performed (S250, S260, S270). That is, when the gas leak is confirmed, the gas valve is shut off, and when the intrusion trace is confirmed, a warning sound is generated.
