1. System background
Auction items are generally collectible and meaningful items, such as antique calligraphy and painting, items used by celebrities, etc. Auction items need to be positioned during the transportation process, and some auction items have special requirements for transportation, such as not being exposed to direct sunlight, and some have specific requirements for temperature and humidity. In the traditional transportation of auction items, the management personnel cannot monitor the auction items in real time, and the transportation personnel sometimes neglect their duties, which will cause unnecessary losses. If RFID technology plus GPS+GPRS technology is used, the auction item needs to be tracked and positioned throughout the transportation process, so that the relevant personnel of the auction item can know the real-time status and location of the auction item, and the security problem of the auction item will be easily solved. , At the same time, it can also achieve the anti-counterfeiting effect of auction items. For this reason, Chuangyi Technology has developed an RFID auction item positioning solution to monitor the transportation of auction items in real time.
2. System overview

When the item is determined as an auction item, the attributes of the item are confirmed, and a label is attached (if it is an auction item that requires temperature and humidity, the temperature and humidity label can be used), and the relevant attributes are stored in the system database corresponding to the label, such as The name of the auction item, auction number, auction location and time, source, etc. When the auction item is in transportation, the GPS module in the electronic tag locates the auction item, and the GPRS module in the electronic tag sends the data to the relevant control center of the auction item. Let the management personnel of the control center get the specific geographic location of auction items at any time. If it is an auction item that requires temperature and humidity, the temperature and humidity during transportation can also be monitored in real time to ensure that the auction item can be stored in a suitable storage range during transportation. When the auction item is successfully auctioned, the PDA can be used to read out the data of the electronic tag, so that the auctioneer can obtain the information of the auction item on the spot. Since there is only one unique id for the same auction item, this serves as an anti-counterfeiting effect.
Three, the system process

When determining the auction item, place the label (which can be a temperature and humidity label) on the side wall of the auction box. The label has the function of GPS+gprs, so that the auction item can be located and transmitted in real time. Before installation, write relevant attributes into the label, such as the name of the auction item, number, auction time, whether the auction was successful, the number of auctions, the source, the auction trader, etc. During the transportation, the label on the side wall of the auction box will locate the auction item in real time and transmit the data to the control center. The control center can read the information of the tag at any time through the host computer, and the management can check the transportation of the auction item at any time.
If an accident occurs during the transportation of the auction item, the management personnel of the control center can find the specific location of the auction item through the PDA or the upper computer of the system. After the auction item is successfully delivered to the auction site, the management personnel who received the auction item use the PDA to verify the information of the auction item, and then receive it after confirmation; at the auction site, the auction master can first display part of the tag data to confirm the auction The authenticity of the product; after the auction is successful, the emcee will read the label data with a PDA and show it to the winner, or use an external printer to print out the data and save it to the winner. At this time, the attribute of auction success or failure in the attributes of the auction item is displayed as “Yes” and the number of auctions is automatically incremented by 1, and the auctioneer adds the relevant data to the attribute of the label.
4. Realized functions and achieved effects

◆Real-time monitoring of auction items in transit to ensure the safety of auction items in and out of the warehouse
◆Improve the supervision of auction items, reduce and eliminate the retention of fake auction items;
◆Real-time auction vehicle positioning and tracking management;
◆High label recognition accuracy, reducing human error input;
◆Statistical reports of various current and historical data of auction items provide managers with accurate and useful information;
◆The connection of the data exchange interface enhances the management of the auction item application system;
◆After the completion of the RFID auction item positioning system, it will provide more valuable and time-efficient analysis data for the auction process;
◆Convert a large amount of paper text information required for auction item receipts into electronic data, which simplifies the query steps. You only need to enter the query conditions to find the required records, which greatly speeds up the query speed;
◆Improve the speed and accuracy of auction data statistics, and reduce the difficulty of the work of summary statisticians.
◆Paperless operation reduces paper expenses;
