, Description:FIELD OF THE INVENTION:
The present invention relates to a food tracebility system. The present invention more particularly relates to food traceability system for perishable food by utilizing IOT.
BACKGROUND OF THE INVENTION:
Perishable foods are described as edible farming products that deteriorate as time passes such as meat, milk, eggs, fruits, vegetables, and all their prepared products. In perishable foods, the dangers of product waste and the reduced lifecycle are serious issues. Food safety is presently considered a central issue for all stakeholders in the food industry. Due to the growing consumer health awareness, food quality and safety have gained much attention. Accordingly, it is crucial for the food industry to upgrade their quality assurance, food product integrity, food safety guarantees, and associated transparency along with the complete food supply chain. A traceability system is considered one of the most essential factors in the modern food industry and it can provide a solution for the food supply chain as it provides tracking and tracing for complete food information in an efficient and trustworthy manner, hence it enhances consumer confidence and ensures food quality and safety.
Radio frequency identification (RFID) is a contactless technology for the automatic identification of objects, animals, and people associated with a transponder (tag). This auto identification technology can be utilized for traceability systems in the perishable food supply chain. It stores data in tags’ memory and the RFID reader then captures the tag data and transfers it to the back-end databases to be accessed remotely to monitor object parameters. Previous studies have showed that, when combined with other types of sensor technologies, RFID provides effective and efficient solutions for food traceability systems to improve food quality and safety. Temperature and humidity are the most critical factors that influence food safety and quality during distribution and storage; thus, the integration of the temperature and humidity monitoring system along with RFID traceability systems is required to monitor perishable food quality in the supply chain and Internet of Things (IoT)-based sensors could be used in temperature monitoring systems. IoT sensors provide efficient food monitoring systems that can assure food quality in real time. Furthermore, RFID can be installed at the warehouse gate to record what tagged products pass through. However, the reader cannot distinguish the direction of tags, i.e. whether they are moving in (received) or out through the gate (shipped). However, the previous studies on tag direction still lack on evaluating different type of tag movement that might be appeared in real case.
Therefore, it is necessary to utilize machine-learning model for identifying the tag direction by considering different type of tag movement, so that it can improve the efficiency of the RFID gate for traceability system. So there is a need for a food traceability system for perishable food by utilizing IOT. The present invention helps in tracking of food product, monitoring of temperature and humidity as well as identifying the direction of the moving RFID tags in the food distribution centers necessary for traceability system. The present invention is a food traceability system based on RFID and IoT sensors to monitor and gather environmental conditions such as temperature and humidity for the distribution of perishable food during transportation and storage. RFID is utilized to track and trace products. The present invention improves the efficiency of the RFID-based traceability into RFID gate such that the direction of tagged products (i.e., received or shipped products) can be identified automatically and to ensure the product’s quality and safety.

DETAILED DESCRIPTION OF THE INVENTION WITH RESPECT TO DRAWINGS:
The present invention is a food traceability system for perishable food by utilizing IOT. The present invention helps in providing a system which can address counterfeiting and the distribution of low-quality product along the supply chain, and IoT sensors are utilized to gather the environmental conditions of perishable food.
In one embodiment, a food traceability system for perishable food by utilizing IOT is disclosed. The system of the present invention comprising of three types of readers such as the RFID gate/fixed reader, handheld reader, and IoT-based sensor. Each RFID gate utilizes a host computer. RFID tags are attached to one side of every product box. When the tagged products move through the RFID gate, the product information is collected by the capturing application and combined with other information (i.e., the location, date, time, and business step) and sent to the database of the website. The present invention utilizes the tag direction module can identify whether the product status is “receiving” or “shipping.” The detailed description of the tag direction is described in the following sub-chapter. The transporter utilizes a flexible/handheld RFID reader to read product information and a smartphone as a handheld reader. The handheld reader operating by reading tagged products and presenting product information in the screen before sending it to the server side. The RFID data is forwarded to smartphones by the dongle reader through the headphone jack. The system of the present invention receives RFID data from the dongle reader, combined it with other information, and sent it to a web service through the cellphone Wi-Fi link. IoT sensors are installed in the producer, distributor, and transporter cold storage to monitor the environmental condition of perishable food throughout the supply chain. IoT based sensor consists of two commercial devices that are, a single-board computer (SBC): microcontroller and an sensor board.
In another embodiment, fresh product is stored in the producer’s cold storage facility by passing through the RFID gate. The product information such as producer name, recorded time, and business step (i.e., receiving) are sent to the database of the website on the server side by the host computer of the RFID gate. When the product is ready to be delivered, it moves through the producer’s RFID gate again before transportation. Similar product information is generated by the capturing application except with different business step information (i.e., shipping) and registered to the database of the website. When receiving a tagged product, the transporter utilizes a handheld reader to record the product information. The handheld reader sends documents such as transporter name, recorded time, and business step (i.e. shipping) to the centralized database of the website. In the next step, the product arrives at the distributor and moves in through the RFID gate for storage. The host computer from the RFID gate sends information such as distributor name, recorded time, and business step (e.g. receiving) to the remote server. Once the product is ready to be delivered to the customer, the tagged product is again moved out through the distributor’s RFID gate. The RFID gate regenerated similar information but with different business step data, which is shipping. Finally, the transporter is ready to deliver the product to the customer. They read the product information using a handheld reader. The generated data such as transporter name, recorded time, and business step (e.g. shipping) are sent to the database of the website by the transporter smartphone device. Once the products had arrived at the customer side, the transporter modified the product status to “delivered” to identify that the product has been received by the customer. Thus, the traceability system can monitor and present the history of product movement in the supply chain.
RFID and sensor data are gathered from the database of the website. The present system permits user access in real-time by PCs, notebooks, or smartphones through a web browser. The system interface presents filtered product information such as product name, recorded date and time, location, and business step. In addition, the environmental conditions gathered from IoT sensors such as the temperature and humidity are stored in the database of the website and presented as graphs so that users can have a better understanding of the product’s condition. Presenting the product history in detail helps users monitor a product’s history and quality in a convenient manner.
The present invention i.e. traceability system based on RFID and IoT sensors provides an integrated platform for the perishable food supply chains which can not only track product movement but also monitor the temperature and humidity of the food product, so that it improves the safety and quality of perishable food products. RFID gate correctly identify the direction of tagged products, whether products are being received or shipped through the gate. The RFID reader’s performance and the impact of tag orientation have been evaluated. The results show that the RFID readers are used for utilization in a traceability system with high performance and could read tagged products despite different tag orientations.
In another embodiment, A food traceability system for perishable food by utilizing IOT comprising of; three types of readers such as the RFID gate/fixed reader, handheld reader, and IoT-based sensor; moving the tagged products through the RFID gate; a flexible/handheld RFID reader to read product information and a smartphone as a handheld reader; collecting the product information and combining with other information (i.e., the location, date, time, and business step) and sent to the database of the website.
