The process of parcel circulation is a more complicated process, because it has to go through many links, such as from the central office to the logistics company, and then to the civil aviation. Each circulation point must be able to clearly check whether the number of packages is correct, so the Tracking management is very necessary. The whole process requires a complete informatization solution. The use of the express bar code can not only improve the work efficiency, but also effectively reduce the occurrence of errors.
1. The structure of the express barcode system
It is composed of an electronic tag attached to the package, a receiving and sending antenna at the entrance and exit, a handheld terminal, a background management platform, and an internal communication network.
●Parcel monitoring center equipment (computer, logistics management software, etc.)
●Access equipment (entry readers, handheld terminals, etc.)
●Gate exit equipment (basically the same as entrance equipment)
●Electronic label (2.4G long-distance active electronic label card can be used)
2. Components of the express barcode system
The first part: the radio frequency long-distance reader, that is, the entrance and exit reader, it is installed at the entrance and exit of each package; it has the functions of directional time-sharing receiving and sending, and reading the fast target card (the card moving speed is greater than 200 km/h);
The second part: electronic label, the system is equipped with a registered electronic label for each goods, it is installed in the appropriate position of the goods, the electronic label is attached with the detailed information and serial number of the goods. There are identification codes and information codes of the items in the box inside the module. When the parcel going into and out of the warehouse reaches about 30 meters from the gate, the reader can automatically detect the identity code (ID) of the parcel, and the ID is loaded in the form of microwave and transmitted to the reader. The information database in the reader is The package is checked and counted, and the information is uploaded to the monitoring package control center through the communication network. The response time of the entire system is only 0.3 seconds; the parcel monitoring center completes the receipt and statistical arrangement of various information at each entry and exit gate and parcel, which is extremely important in time for anti-theft and emergency adjustments.
3. The construction of the environment of each circulation site of the express bar code
●The staff in the parcel assembly area of the central office use the handheld terminal to read the selected goods information.
●The logistics center installs radio frequency long-distance readers to realize the number review and complete the distribution work while carrying out the distribution of goods.
●The staff of the Civil Aviation Administration use handheld terminals to realize the number review and complete the distribution work while carrying out the cargo distribution.
●Using the programmer to write data to the electronic tag, the content includes a series of descriptions that the customer wants to add, including time, location, variety, quantity, serial number and other information;
●Each small item is outsourced by PVC. In addition to attaching an anti-disassembly electronic paper label to the seal, it also uses a 2.4G active electronic label.
4. Express barcode workflow
1) The central office affixes the corresponding electronic label to each small item, and puts the electronic label on the outer box after packing the box. Through infrared, when the package going into and out of the warehouse reaches about 30 meters from the gate, the reader detects the package The existence of all the small pieces in it. The reader uploads the number in the electronic label of the package to the monitoring center through the communication network. The entire system response time is only 0.3 seconds. The monitoring center uses computers to manage and archive data and transmit the data to the logistics company and the civil aviation center monitoring center. The goods are sent to the logistics company.
2) After receiving the package, the logistics company uses the handheld terminal to detect the number of the electronically labeled item in the shipped package, and the reader sends the information to the database to check and count the package. After checking the express barcode information, make sure that the quantity of the goods is correct and sent to the airline.
3) After the civil aviation receives the package, it uses the handheld terminal to detect the number of the electronically labeled article in the shipped package, and the reader sends the information to the database to check and count the package. After checking the barcode information of the courier, ensure that the quantity of items is consistent with the data uploaded by the central office.
