Application of Internet of Things Technology in Tracing to Food Source

Abstract:

At present, one-dimension codes are printed on food packaging, so is the bar code on the same kind of food. However, this method can only manage the same type of food. It cannot manage the single food. For this reason, we cant achieve the goal of tracing to the food source. The model of Internet of Things mainly includes the perceptual layer, the transport layer and the intelligent application layer. The perceptual layer recognizes objects through sensing devices and collects the exclusive identification on food, then connects to the wireless network or wire network through interface. In transport layer, by means of internet or LAN, the data which has already been collected by the perceptual is transferred to the information center or network administration center for processing and analyzing. According to the needs of tracing to food, the application layer source provides service call interface or API platform service to reach the depth integration of the information and traces to food source management, which can realize the intelligent operation management of food manufacturing and circulation. This paper proposes the Sense organs of Internet of Things, which is composed of the two-dimensional code technologies, RFID technology and sensor technology, wireless sensor networks or wired sensor networks composed of "nervous system". And then it makes full use of the variable information printing technology to print exclusive code on the single food packaging, and uses RFID reader register large quantities of food rapidly. It also uses database management software and user terminal to track the whole process of food production and circulation, in which food can be checked and inquired by network search platform.
