1. System background
The tracking system for postal parcels is a high-tech automation product that combines the mature smart card technology, wireless communication technology, and advanced software technology of Modern Technology Co., Ltd., and organically integrates various mature technologies.
The process of parcel circulation is a relatively 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 it is correct. The tracking management is very necessary.
For this reason, our company has launched a solution based on the 2.4G long-distance radio frequency card “Postal Special Package Item Tracking System”.
2. System brief introduction
1. System structure
It is composed of an electronic tag attached to the package, a transceiver antenna 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 (2.4G long-distance active electronic label card can be used)
2. System components
The first part of the ML-M2000 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 fast target cards (the card moving speed is greater than 200 km/h)
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 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 all entrances and exits and parcels, which has extremely important timeliness for anti-theft and emergency adjustments.
3. Construction of the environment of each circulation site
The ML-M2000 remote reader is installed in the parcel assembly area of the central office to read/write the selected goods information into the electronic label on the parcel.
The logistics center is equipped with ML-M2000 long-distance readers, which realizes the number review and completes the distribution work while carrying out the distribution of goods.
The Civil Aviation Administration installs ML-M2000 long-distance readers to realize the number review and complete the distribution work while carrying out cargo diversion.
Use 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;
Every small item is outsourced by PVC, and an anti-disassembly electronic paper label is affixed to the seal. 2.4G active electronic tags are also used.
4. Work flow
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 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 uses the ML-M2000 remote reader to detect the number of the electronically labeled item in the shipped package, and the reader transmits the information to the database to check and count the package. Make sure that the quantity of goods is correct and sent to the airline.
3) After civil aviation receives the package, the ML-M2000 long-distance reader will detect the number of the electronically marked item in the shipped package, and the reader will send the information to the database to check and count the package.Ensure that the number of objects is consistent with the data uploaded by the central office.
5. Product introduction:
Long distance: easy to achieve within 10 meters of reading distance. Due to the actual situation of the attendance location, the card reading distance can be set.
Stable operation: The active card has a stable reading distance and is not easily affected by the surrounding environment. Using channel isolation technology, multiple devices do not interfere with each other;
Support high-speed mobile reading: The identification card can move at a speed of up to 200 km/h.
High reliability: it can operate normally within the ambient temperature of -40℃-85℃ (MTBF≥70000 hours), especially in the low temperature in the north and high temperature in the south, it has more advantages, and it can effectively resist high dust and dust in the air in harsh environments. The normal use of equipment can be ensured in environments such as pollutants and rainy weather.
Encrypted calculation and authentication to ensure data security and prevent link eavesdropping and data cracking;
High anti-interference and lightning protection design: There are no special requirements for various interference sources on site, meeting the requirements of the industrial environment, and the installation is convenient and simple.
There is no need to apply for and pay for the ISM microwave frequency band that is open worldwide.
Ultra-low power consumption: long service life, low average cost, and it is safer and healthier for the human body without radiation damage. Configurable microwave module working mode, adjustable transmission power;
Multi-identification: It can identify more than 200 signs at the same time. If there are more than 200 signs on the spot, we have a way to deal with it.
