Description

INTELLIGENT SENSOR MIDDLEWARE STRUCTURE CAPABLE OF SELF ADABTING}

The present invention relates to an intelligent sensor middleware structure that can be adapted to various environments and configured for a smart environment.

Conventional technology mainly focused on the invention and research focused on the efficiency of the sensor network, but not many technologies incorporating intelligent systems. Algorithm based technology research to increase network efficiency was the main content.

Because it was an algorithm-oriented technology study, it was more suitable for the sensor network structure suitable for a specific environment than for various environments.

An object of the present invention is to propose an intelligent sensor middleware structure capable of adapting to various environments and constructing a smart environment.

In order to achieve the above object, according to a preferred embodiment of the present invention, for the middleware configuration of the individual sensor node for the sensor network configuration for various environments, the basic configuration of the network, IP allocation, network frequency allocation, etc. A network manager for managing and setting basic element information; A network topology manager for managing and determining an overall network topology; An adaptive rule manager for changing a rule according to an individual operation of a sensor node and a network situation; An adaptive rule engine unit which manages the entire rule engine based on the changes or modifications made by the adaptive rule manager; A sensor middleware architecture is provided that includes a reset manager that manages and configures battery and non-network issues of the sensor node.

By applying the intelligent system and the adaptive middleware technology to the sensor network through the present invention, it is possible to enable a network structure in which the sensors adapt themselves to the environment without the user having to manage and repair individually. In addition, the sensor network and sensor that can be applied to various environments are expected to be used more universally.

1 is a system configuration diagram according to the present invention.

As the invention allows for various changes and numerous embodiments, particular embodiments will be illustrated in the drawings and described in detail in the written description. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. Like reference numerals are used for like elements in describing each drawing.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the same reference numerals will be used for the same means regardless of the reference numerals in order to facilitate the overall understanding.

1 is a diagram illustrating a middleware structure of a sensor node. It is divided into four configurations, and through this, it is organically exchanged information with other nodes and changes its internal middleware structure to adapt to the environment. The network element unit 100 manages the basic configuration of the network. The network manager 101 is a unit that receives the status of the adjacent sensor node and various information of the data table unit 120 and manages the overall network. The network topology manager 102 is configured with a network manager to configure a topology suitable for the situation. It is a department to select and manage. The reset management unit 110 is a unit for identifying and managing not only the network of the sensor but also the overall setting and status. Data table unit 120 is a table for storing various information of the network and the sensor to store and update it, the sensor module profile unit 121 for storing the ID and individual information of the sensor module, access in any form on the network Routing parameter unit 122 for storing information on whether or not, policy and rule management unit 123 for rule and policy management based on the rule, battery parameter unit 124 for grasping the battery status, variables for the environment It consists of variable management 125 for input and storage. The data table does not perform its own function, but it stores such information and provides the necessary information from others. The adaptive middleware element unit 130 includes information on rules for configuring the sensor network and determining the situation. The adaptive rule management unit 131 applied to the network situation is updated by a server or a user, Performing the appropriate rule management and the adaptive rule engine unit 132 provides the basis of these rules.

When sensor nodes composed of basic sensor middleware are distributed, individual sensors send configuration messages for communication with sensor nodes and servers in the first place. As such, the individual sensors create a map of the surrounding sensors and store them in the routing parameter 122, and the collected data of the individual sensors is transmitted to the server to form an overall sensor map configuration. Among the maps configured in this way, the server sets the management sensor for each node or distance in consideration of the maximum allowable distance from one node. The configured sensor manages the peripheral sensor as described in FIG. 1, and the server does not need to have information of all the sensors, and manages only the management sensor to reduce the burden to be performed in the server.

Preferred embodiments of the present invention described above are disclosed for purposes of illustration, and those skilled in the art will be able to make various modifications, changes, and additions within the spirit and scope of the present invention. Additions should be considered to be within the scope of the following claims.
