Abstract:
The present invention relates to a system for managing a low-temperature storage supporting a variable operation environment, eliminating the necessity to configure a new storage management system even though a type of a storage is changed. More particularly, the present invention relates to a system for managing a low-temperature storage capable of applying changed information to manage a storage even when good items within the storage, a position of the storage, a sensor disposed within the storage, and a device disposed outside of the storage are changed, thus eliminating the necessity to newly establish or change a storage management system. The system for managing low-temperature storage comprises an environment managing unit receiving data from an environment managing sensor from each storage, managing an environment of each storage based on the received data, and reflecting a change in position, amount, and type of the environment managing sensor; a stock managing unit receiving data from a stock managing sensor of each storage and managing stock of food items based on the received data; an information managing unit reflecting information regarding a change in food items and information regarding a change in a storage through a user command; a device control unit controlling an external device for adjusting an environment of the interior of each storage and reflecting information regarding a replacement of the external device; a DB connecting unit receiving data from the environment managing unit, the stock managing unit, the information managing unit, and the device control unit, and storing the received data through a connector class; and a data distributing unit analyzing sensing data received through a communication unit and distributing the analyzed sensing data to each unit; and a user interface unit receiving a user command and outputting a data value to a user.
Abstract:
PURPOSE: A system providing a context awareness service for home network service control and a method thereof are provided to infer the current situation by comparing an inference data service request of a home network device and a generated home network event with a look-up table, thereby automatically providing a corresponding home network service through the awareness and inference of user behavior and situation information in a home network environment. CONSTITUTION: Multiple sensor nodes (25) monitor and output the instruction and state of each object and a neighboring environment event. A home network server (210) is wirelessly connected to one or more home network devices (20-22) and the multiple sensor nodes and controls the home network devices. The server registers information about a characteristic ontology model for each home network device and a context inference rule. A context awareness management server (212) infers and analyzes the registered information, executes a service for each object, and adaptively implements the service according to the characteristics of a neighboring environment.

Abstract:
PURPOSE: A monitoring system and a method are provided to offer the information such as level of food freshness, freshness preservation period, and whether rotten or not using the level of ethylene, humidity, temperature, and carbon dioxide. CONSTITUTION: A DB (100) stores operating information of a storage and food storage information. The DB (100) stores the storage operating information and food custody information. A sensor (200) senses the inner condition of the food storage. A sensing information acquisition unit (320) is transmitted sensing information from the sensor and, stores the sensing information. A food storage information acquisition unit (310) is transmitted food storage information from the DB, and stores the food storage information. A storage operating information acquisition unit (340) is transmitted storage operating information from the DB, and stores the storage operating information. A food descriptive data acquisition unit (330) obtains a descriptive data of stored food from the DB. A control unit (350) calculates whether rotten or not and food freshness, and freshness preservation period. The sensing information is at least one of ethylene concentration, carbon dioxide concentration, temperature, or humidity.
