Abstract:
1. A ubiquitous sensor network-based system for automatically managing food sanitation, comprising: at least one sensor node configured to have an IP address and installed in a specific region, including at least one kitchen appliance, the sensor node being configured to measure and store sensing information, including temperature, humidity, pH, and odor information, at preset periods, to compare measured values with preset values, to generate a warning message and transmit the warning message to at least one management server when the measured values deviate from a range of preset values, to receive a control command for the kitchen appliance from the management server, and to control the kitchen appliance; a sink node configured to relay between the sensor node and the management server and between the mobile terminal and the management server, thus storing data transmitted to or received from the management server; a mobile terminal configured to have an IP address and to read food information using a RFID reader or a barcode reader, transmit the food information to the management server through the sink node, measure and store sensing information, including temperature, humidity, pH, and odor information, at preset periods, compare the measured values with preset values, generate a warning message and transmit the warning message to the management server when the measured values deviate from a range of preset values, and receive a control command for food from the management server; and the management server configured to determine whether the data received from the sensor node or the mobile terminal is a measured value of the kitchen appliance or food, or a warning message, and configured to generate a control command corresponding to the warning message, transmit the control command to the sensor node or the mobile terminal, notify a manager of an urgent situation and a location of the kitchen appliance, arrange the data received from the sensor node or the mobile terminal in a database, analyze/store the received data in a format of Hazard Analysis Critical Control Point (HACCP) on a basis of the database, and output the analyzed/stored data if it is determined that the received data is the warning message.
