Conveyor belt sushi inventory and freshness detection method

Abstract

The invention relates to a food detection method and especially relates to a conveyor belt sushi inventory and freshness detection method. At least one radio frequency antenna capable of reading chip information is set. According to a bench rotating speed of rotation sushi, a referenced maximum time interval TM which is a maximum time interval for the radio frequency antenna to read a same chip is set. The radio frequency antenna reads chip information and transmits to a processing center. A processing center establishes an original time stamp when receiving information for the first time. When the radio frequency antenna reads the same chip again, time is accumulated. After the TM, if the same chip information is not read, time stamp information corresponding to the same chip information is deleted. Through the above method, a sushi rotation bench is detected and managed; an inventory number of food on the sushi rotation bench, storage time and freshness can be timely and automatically managed; and information of existence time, sale quantities, a sale period and the like of various kinds of food can be timely calculated.
