In the past, computers were used to automate all the phenomena existing in the natural world, but nowadays, rather than moving all the phenomena of the natural world to the computer, the computer is replaced with objects and phenomena to solve the whole as one phenomenon.

At this stage, Ubiquitous Sensor Network (USN, UBIQUITOUS SENSOR NETWORK) is used to collect all the signals of all things into the system and connect and process each piece of information with the nervous system. There are many ways and systems to classify information in these USNs, and there are many different uses for information.

In such a situation, there is an ongoing process of organizing equipment and procedures for interlocking various sensors on the USN, and efforts are being made to minimize interference or efforts of information users who use the information. Sensor standardization technology using information and communication technology is being developed.

Specifically, various technologies for interlocking sensors are being used in USN, which is a next-generation communication network, and these technologies are progressing to increase their utility in constructing an effective USN sensor system.

The sensor information processing system using USN technology can be divided into a public disaster prevention system that provides services to an unspecified number of people for the public benefit, and a personal disaster prevention system to directly help the individual's life.

On the other hand, Universal Plug and Play (UPnP), a protocol that enables automatic detection and control of various devices, is adopted in general user PCs or terminal information processing systems, data hubs, peripherals, and IP networking environments other than the sensor network (USN). UPnP requires a certain amount of computing power for each device, and design protocols based on IP networks, which are not immediately applicable in USN environments that feature limited resources and diverse networks for each device. There is a difficult problem.

In addition to UPnP, Home Audio Video Interoperability (HAVi) and JINI, which are protocols that provide interoperability for automatically connecting and manipulating devices, have been proposed. These devices are mainly used in home networking environments.

Or USN sensor access protocol with adaptive control function that responds to system changes even in dynamic and complex USN environment by applying it to entire system such as terminal information processing system or data hub. The aim is to provide ACP.

The present invention actively constructs a system that collects and processes sensor information using USN, and actively responds to system changes such as installation or removal of various sensors and systematically collects data from each sensor. The USN Sensor Access Protocol (ACP) has an adaptive control function that enables real-time monitoring and construction of public or private disaster information DB.

Identifying and allowing the hub or sensor device to proceed with the operating software update procedure if necessary; The connection between the sensor device and the hub, the hub and the ACP server, the ACP server and the user or user terminal is made, but when the ACP server requests the connection of the sensor device from the hub, the connection procedure can be completed by informing the user. Connecting step to make; An authentication step of performing a procedure for authentication of each individual only when the data measured by the sensor device is not a single region or a plurality of individuals; A data transmitting / receiving step of transmitting real-time data and non-real-time data according to the characteristics of the sensor or transmitting data separately classified according to the periodic characteristics of the data; A control step of performing a control on the data transmission and reception, changing a data transmission / reception scheme as necessary, and controlling a sensor device and a hub from a user or an ACP server; In the case where the sensor device targets multiple individuals, when the target individual is changed, the hub requests a disconnection from the ACP server and causes the ACP server to inform the user of the fact; An end step of causing the sensor device to exit when the user leaves the USN network or the user logs out is characterized in that each component of the system operates while the state transitions.

In this case, the communication procedure must conform to the interconnection reference model standard between open systems, and is made to operate with compatibility for each layer, and the protocol processing is mainly performed at the application layer.

The present invention not only makes it possible to automatically transmit data received from various types of information collection sensors to a server, store and utilize the data, and can also remotely control a plurality of sensors. The sensor, hub (or gateway), server, user PC Alternatively, each component of the entire system, such as a terminal information processing system or a data hub, can be operated according to a predetermined procedure to efficiently respond to system changes even in a dynamic and complex USN environment.

The present invention can be usefully applied to the information processing environment of the intelligent sensor hub system, through which various sensor information can be systematically collected and managed without being affected by external environmental changes, and accurate judgment can be made according to various situations. By providing an adaptive control-based standard for sensor devices, it is possible to provide users with the ability to actively and easily connect sensors to a variety of sensor devices, different manufacturers for each type of sensor device, and numerous product versions for each manufacturer. To help.

The data transmission / reception step S5, the control step S6, the disconnection step S7, and the termination step S8 allow each component of the sensor information processing system to operate while transitioning states.

First, the registration step S1 is a preliminary preparation step, in which various necessary information such as types of sensors existing in the network are registered.

These properties include a user including the ACP protocol version, sensor device name and type, hub interface type (serial, USB, Zigbee, Bluetooth), identification information, initial configuration information, authentication information for each user, and the scope of authority. For example, information.

Second, the identification step (S2) is a step in which a plurality of information processing remote sensor device 10 and the user 40 constituting the sensor collection information system starts when entering the USN network, first the sensor device 10 is a hub When the physical connection is made to the 20, the sensor device 10 transmits identification information of its own device to the hub 20, and the hub 20 queries the ACP server 30 for the ACP. The server 30 transmits initial setting information and operating software version information of the sensor device 10, and if the hub 20 or the sensor device 10 is required, the operating software update procedure is performed.

The user 40 performs a login procedure to the terminal in this identification step.

Third, the connection step (S3) is a step to make a connection between the sensor device 10 and the hub 20, the hub 20 and the ACP server 30, the ACP server 30 and the user 40, the sensor If the data is real time and streaming information, the P2P connection is made between the sensor device 10 and the user 40 or between the hub 20 and the user 40.

In this case, the user 40 is in a state of informing the ACP server 30 of the sensor list to receive data in advance, and the ACP server 30 corresponds to a case where the connection request of the sensor device 10 from the hub 20 is received. By notifying the user 40, the connection procedure can be completed.

In addition, when the connection procedure is completed and the connection is established, the ACP server 30 creates a data storage space in the ACP server 30 or mediates the P2P connection if necessary according to the characteristics of the sensor data.

Fourth, the authentication step (S4) is a step for authenticating only when the data measured by the sensor device 10 is a single area or a plurality of individuals, when the sensor device 10 is used for an individual In this step, a procedure for authentication of each individual is performed, and an RFID tag is used for authentication of each individual, or the personal information of the sensor device 10 is directly input from the hub 20.

Fifth, the data transmission and reception step (S5) is a step for transmitting real-time data and non-real-time data according to the characteristics of the sensor or to transmit the data in accordance with the periodic characteristics of the data, the user 40 as needed It is possible to receive data using a push technique, in which case the ACP server 30 allows the user 40 to deliver the desired data as soon as it arrives.

Sixth, the control step (S6) is a step to control the sensor device 10 and the hub 20 from the user 40 or the ACP server 30, the control such as start / stop / stop for data transmission and reception It is possible to change the data transmission and reception method as needed.

At this time, the hub 20 or the sensor device 10 should provide a script or web page to control itself, the ACP server 30 or the user 40 by using the script or web page to the corresponding hub ( 20) or to remotely control the sensor device 10.

Seventh, the disconnection step (S7) is a step performed when the target device is changed in the case where the sensor device 10 targets multiple individuals, the hub 20 is to disconnect the connection to the ACP server 30 Request and have the ACP server 30 inform the user 40 of this fact.

At this time, when the P2P connection is made in the connection step, it is a step of releasing it, and also releases resources such as temporary storage space for data transmission and reception provided in the ACP server 30.

Eighth, the terminating step S8 is a step performed when the sensor device 10 leaves the USN network due to power off or failure, or when the user 40 logs out.

The sensor device 10 or the user 40 that has gone through this termination step (S8) must go through the identification step (S2) again, and if the abnormal termination does not go through the disconnection step (S7), it must be performed in the disconnection step. Let's get things done

As a result of implementing the personal health care service using the USN sensor access protocol having the adaptive control function of the present invention, it shows that the personal biometric information can be monitored in real time, and through the real-time monitoring of such personal biometric information It will be able to make accurate judgments about and cope with the individual's physical emergency and provide a foundation for living a convenient and happy life using new IT technologies.
