1. Project features
The biggest feature of the project is that it combines the mature smart card technology, wireless communication technology, and advanced software technology of Modern Technology Co., Ltd., organically integrates various mature technologies, and applies them to actual engineering needs such as parcel in and out, stacking, and transportation monitoring.
① Project requirements: Central Bureau-Logistics Company-Civil Aviation During the process of parcel circulation, each circulation point must be able to clearly inquire whether the number of parcels is correct, the movement of the parcel, if lost or.
② Selection of equipment:
a. Choose contemporary communication DRF-8804A one-to-four reader mainframe, its single mainframe can be connected with four antennas, and the antennas work in time-sharing sequence, which can meet the application places with one gate and multiple reading needs; install and set at the entrance and exit
b. The outer box of the package uses recyclable electronic tags, and the items in the box use non-recyclable anti-disassembly paper tags.
2. System function
The device’s molecular system system and package monitoring center:
●The subsystem is an RFID read-write system provided by contemporary technology, which consists of two parts:
The first part is the DRF-8804A type four-channel split long-distance reader, that is, the entrance and exit reader, which is installed at the entrance and exit of each package; it has a four-antenna time-sharing transceiving, reading and fast target card function (card moving speed greater than 120 kilometer)
The second part of the 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 8-12 meters from the gate, the reader detects the presence of the parcel through infrared induction. Start the gate reader to detect the identity code (ID) in the electronic tag of the incoming package. The ID is loaded in the form of microwave and transmitted to the reader. The information database in the reader checks and counts the package. The communication network uploads the information to the monitoring and parcel control center. The response time of the entire system is only 0.3 seconds.
●Parcel monitoring center Completes the receipt and statistical arrangement of various information about each entry and exit gate and package, which is extremely important for anti-theft and emergency adjustment in time.
3. System composition
It is composed of an electronic tag attached to the package, an antenna for receiving and dispatching at the entrance and exit, a tag reader, a background management platform and an internal communication network.
●Parcel monitoring center equipment (computer, logistics management software, etc.)
●Access equipment (entry readers, tag readers, etc.)
●Gate exit equipment (basically the same as entrance equipment)
●Electronic label (optional non-recycled paper label, with anti-disassembly and low price advantages)
4. Work flow
Construction of the circulation site environment
●The DRF-8804A four-channel split remote reader is installed in the parcel assembly area of the central office to read/write the selected cargo information into the electronic label on the parcel.
●The logistics center installs a DRF-8804A four-channel split long-distance reader, which realizes the number review and completes the distribution work while carrying out the distribution of goods.
●The Civil Aviation Administration of China installed DRF-8804A four-channel split long-distance reader to realize the number review and complete the distribution work while carrying out cargo diversion.
●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 with PVC, and an anti-disassembly electronic paper label is affixed to the seal. Recyclable electronic tags are used on the top and left and right sides of the main outer box.
specific process:
1) The central office affixes the corresponding electronic label to each small item, and puts the electronic label on the four sides of the outer box. When the package going into and out of the warehouse reaches 8-12 meters from the gate, it is detected by the sensor and the reader To the existence of all small items in the package. Reader, the identity code (ID) in the electronic tag of the package, the ID is loaded in the form of microwave and transmitted to the reader. The information database in the reader will check and count the package, and upload the information through the communication network for monitoring center. The response time of the entire system 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 the logistics company receives the package, it activates the RFID reader at the gate to detect the identity code (ID) of the electronically marked item in the incoming package. The ID is loaded in the form of microwave and transmitted to the reader. The information database checks and counts the package. Make sure that the quantity of goods is correct and sent to the airline.
3) After the civil aviation receives the package, it activates the RFID reader at the gate to detect the identity code (ID) of the electronically marked item in the incoming package. The ID is loaded in the form of microwave and transmitted to the reader and the information in the reader The database checks and counts the package. Check whether the quantity of goods is consistent with the data uploaded by the central office. Make sure it is correct and send it to the destination.
advantage:
Ensure to track and monitor the specific information of each link in the package circulation, avoid missing items during the circulation process, and know the detailed information of each item in the package without unpacking.
