fig. 3 is the flow chart of the warehousing and ex-warehouse of the goods of the utility model.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the RFID-based food warehouse management system includes an RFID electronic tag in signal connection with a microprocessor module, a radio frequency identification module, an alarm module, a storage module, a display module, and an input module; the microprocessor module is used for processing and outputting a control signal to prompt the completion of correct storage and taking of the goods in the warehouse, goods information is written in the RFID electronic tag and is attached to a goods package, and the radio frequency identification module is used for reading the RFID tag information of the goods; the alarm module is used for outputting alarm information and outputting the reason of the alarm on the display module.

The RFID tag is a passive electronic tag with an ultrahigh frequency working frequency band, comprises a signal receiving and memorizing circuit, a code modulation and demodulation circuit and a signal feedback circuit, and information of goods, such as goods names, goods quantity, shelf numbers and layer numbers, warehousing time, expiration time and the like, is written in the tag and is attached to a goods package.

The input and output modules are divided into two types, if the reader is fixed, the input module is a keyboard, a mouse and the like, and the output module is a liquid crystal display screen; if the reader is handheld, the input module is a virtual key of a touch screen type liquid crystal display screen, and the output module is the liquid crystal display screen.

The alarm module is internally provided with a buzzer, when the conditions of overdue goods, insufficient quantity of goods, misplaced goods in warehouse-out and the like are met, the microprocessor can activate the alarm module, and the buzzer sounds and outputs the alarm reason on the display screen.

The storage module is a database, all the readers share the database, all the received RFID electronic tag information and the goods states are stored in the database, and if the RFID electronic tag information and the goods states are sufficient or not, the readers can access and rewrite the information.

As shown in fig. 2, each layer of shelf is provided with a signal receiver 1, each receiver is connected with a processor module, received information is output through a display screen 2, the display screen is a touch screen type liquid crystal display screen, a virtual key is arranged in the display screen, and operation can be performed through a touch screen mode.

The radio frequency identification module receives information of the RFID tags, such as the names of goods, the quantity of the goods, the number of the shelf where the RFID tags are located, the number of the layers where the RFID tags are located, the warehousing time, the expiration time and the like, transmits the received information to the microprocessor module and then stores the information in the storage module to form a database. The staff accesses the goods information in the database through the input module, and then feeds the information back to the staff through the display module. When the radio frequency identification module reads wrong information, such as overdue goods, insufficient quantity of goods, misplaced goods and mistaken goods, the alarm module is triggered to remind staff.

As shown in fig. 3, when goods are put in storage, the staff attaches the RFID tag written with information about the goods, such as the name of the goods, the number of the shelf where the goods are located, the number of the floor where the goods are located, the storage time, and the expiration time, to the packaging bag of the corresponding goods, and transmits the written information to the storage module, and finally puts the goods on the corresponding shelf location to complete the storage of the goods. If the staff puts the goods in wrong position department, the signal receiver on the goods shelves will receive wrong position signal, and microprocessor module will activate alarm module, and the display screen on the goods shelves also can export and remind the characters, reminds the staff to put the goods in correct position department.

The system reads time information and quantity information of the goods in real time, when the goods are overdue or the goods are used up, the alarm module is triggered, the display screen outputs reminding information to remind staff of timely processing the overdue goods and timely supplementing the goods, and the goods in the warehouse are guaranteed to be in a state of being capable of being normally used all the time.

When the staff gets goods and goes out of the warehouse, the input module accesses the storage module to check the position of the staff, the display screen outputs the position information of the goods, and the staff can get the goods from the corresponding goods shelf. After the signal receiver on the goods shelf receives the information of the goods to be taken, the signal receiver accesses the storage module to update the quantity of the goods, and when the quantity of the goods is not enough, the signal receiver triggers the alarm module to remind staff of replenishment.

When warehouse checking is carried out, the input module accesses the storage module, information of all goods is checked, then goods which are overdue or are about to be overdue are retrieved, staff go to the corresponding shelves to clean the goods, and the signal receiver on the shelves accesses the storage module to update the quantity of the goods in the database after reading the information of the goods. Then, the goods with less quantity and used up are retrieved, and the staff contacts the purchasing department for replenishment.
