METHOD AND SYSTEM FOR MONITORING STATE OF FOOD
The present disclosure relates to a method and a system for monitoring state of food. In one embodiment, the method received data related to parameters associated with food storage conditions including temperature, humidity, defrost duration and defrost stop temperature and determines deviation of the food storage conditions based on the received data. Further, the method determines deviation in temperature and duration period of deviation and notifies a user if the duration period where the food is in danger zone exceeds a predetermined critical threshold duration period. Further, the deviation of defrost duration and humidity is also determined and notified to the user accordingly so that the user may reduce the duration of opening the door of cold-room, and frequency of such opening. Thus, the present disclosure periodically determines the deviation in critical conditions and enables the user to control the operations of the food storage conditions avoiding food wastage.
1 . A method of monitoring state of food, said method comprising:
receiving, by a processor of a food state monitoring system, from at least one sensor at regular time intervals, data related to conditions of one or more locations where the food is stored wherein the data comprises at least temperature data;
determining, by the processor, a deviation in temperature by comparing the received temperature data with a predetermined threshold temperature;
deriving, by the processor, duration of the deviation between two consecutive first and second times;
determining, by the processor, whether the deviation duration exceeds a predetermined critical threshold duration; and
generating, by the processor, an alarm signal indicative of state of food based on the determination.
2 . The method as claimed in claim 1 , wherein the first time indicates a first timestamping when the deviation in temperature is determined and the second time indicates a second timestamping when no deviation in temperature is determined.
3 . The method as claimed in claim 1 , further comprising receiving data including at least a humidity data, and a defrost duration data.
4 . The method as claimed in claim 3 , further comprising:
setting a deviation flag if the duration of deviation is determined to exceed the predetermined critical threshold;
upon setting the deviation flag, determining if the defrost duration data and humidity data deviates from the respective predetermined threshold limits; and
generating the alarm signal indicative of deviation upon determination.
5 . The method as claimed in claim 1 , further comprising:
determining a count of deviations during defrost duration and maximum of one or more defrost deviation durations recorded for a predetermined time period; and
transmitting one or more notifications to a user to control the operations of handling the food based on the count of deviations and maximum defrost deviation duration thus determined.
6 . A system for monitoring state of food, said system comprising:
a processor;
a plurality of sensors communicatively coupled with the processor; and
a memory disposed in communication with the processor and storing processor-executable instructions, the instructions comprising instructions to:
receive data related to food conditions from at least one sensor at regular time intervals, wherein the data comprises at least temperature data;
determine a deviation in temperature by comparing the received temperature data with a predetermined threshold temperature;
derive duration of deviation between two consecutive first and second times;
determine whether the deviation duration exceeds a predetermined critical threshold duration; and
