Hazard Analysis Critical Control Point (HACCP) is a hygiene management system that prevents biological, chemical, and physical hazards from being incorporated or contaminated in the food at each stage from raw material production to final consumer intake.

HACCP is not a concept to ensure safety by inspecting the final product, but it is a preventive concept to secure and guarantee the safety of product or food by continuously managing through production, distribution and consumption of food. Therefore, HACCP is a planned management system to ensure the safety, soundness and quality of food by monitoring activities to prevent food poisoning. HACCP consists of Hazard Analysis (HA) and Critical Control Point (CCP). The HA analyzes and evaluates potential hazards according to the flow of major definition, and CCP means the risk factors to be emphasized in the identified hazards. HACCP establishes CCP in the whole process and manages it according to the set standards at each CCP branch to prevent the risk in advance and to secure food safety. HACCP has been applied to the site in accordance with the 12th and 7th principles set forth in the International Commission on Food Standards (codex).

In order to improve the health of students and consumers through balanced nutrition and to supply harmless foodstuffs safely, HACCP is used in many food circulation processes such as school meal system and general restaurant, and environmental data of food preparation, storage, A food management system is needed to sense and manage the temperature and pH of food.

6 is a diagram for explaining an embodiment applied to a place where a food service system based on HACCP provides a food service.

Referring to FIG. 6, the sensor network includes a first sensor sub-network 510 installed at the inspection site, a second sensor sub-network 520 installed at the storage site, a third sensor sub-network 330 installed at the cooking location, And a fifth sensor sub-network 550 installed at the washing place.

The first sensor sub-network 510 may include a temperature sensor 512 and a router 314 included in the delivery vehicle. The second sensor sub-network 520 may include a temperature sensor 522, a humidity sensor 524, and a router 526. The third sensor sub-network 530 includes a gas leak detection sensor 532, a tap water contamination detection sensor 534, a temperature sensor 536, a humidity sensor 537, a bacteria detection sensor 538 and a camera sensor 539 . The fourth sensor sub-network 340 may include a temperature sensor 541, a humidity sensor 542, a camera sensor 543, and a drinking water contamination detection sensor 544. The fifth sensor sub-network 550 may include a camera sensor 542 and a tap water contamination detection sensor 544.

The sensor network management system 530 determines a Critical Control Point (CCP) based on the analyzed risk factors shown in Figs. 7A to 7B. Critical management points can be determined according to the user's choice or the user's requirements. For example, the sensor network management system 530 may determine an improper delivery temperature as the critical management point in the risk factor column of FIGS. 7A-B. The HACCP management system 530 configures the sensor network by determining suitable sensors to manage critical management points. For example, the HACCP management system 530 may determine that a temperature sensor is needed and configure the sensor network 500 using the temperature sensor 512. The first sensor sub-network 510 can be dynamically configured because the shipment can be moved. The HACCP management system 530 can determine the set of sensors needed based on critical management points, add other sensors as needed, or delete sensors in the set. For example, in the case of improper delivery temperature, the HACCP management system 530 can determine the set of temperature sensors and add humidity sensors to the set as needed. According to one embodiment, the sensor network management system 130 may configure the configuration of the sensor according to critical management points. For example, if the steady state of the temperature sensor 322b corresponds to a temperature between 2 degrees and 8 degrees Celsius, then the HACCP management system can set the steady state of the temperature sensor 322b to a temperature between 2 degrees and 8 degrees Celsius , The temperature of the refrigerating compartment can be checked.

In an embodiment, the HACCP management system can determine whether a critical element has occurred at a critical management point based on sensing data sent from the sensor. For example, if the temperature transmitted from the temperature sensor 322b corresponds to 10 degrees Celsius, the sensor network management system 130 may determine that a temperature anomaly has occurred in the refrigerating compartment. As another example, if the temperature sensor 322b can directly check whether the temperature is abnormal, the HACCP management system receives a message indicating the abnormal state transmitted from the temperature sensor 322b and determines that a temperature abnormality has occurred in the refrigerating chamber . The HACCP management system can notify the manager who manages the critical point when a risk occurs, that the risk has occurred. For example, the HACCP management system can notify an administrator of the occurrence of a risk factor by using SMS (Short Message Service), e-mail, voice call, or the like.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It is not limited to the embodiment.
