Application of RFID electronic seals in coal and mineral transportation monitoring system
chrispeng [ad_1]
As the price of coal products rises, cheating such as replacement and shoddy coal often occurs during transportation, causing huge economic losses to enterprises. At present, the more conventional protection methods are the use of seals, lead seals, mechanical locks, etc. These methods have little effect, are easy to crack, and only increase the trouble for cheaters.
The so-called electronic seal technology refers to an authentication technology that can record whether the carriage or other hard packaging has been secretly opened, and can automatically call the police when it is opened illegally. The electronic seal can realize the automatic identification of the container, record the relevant information of the cargo transportation in the electronic label of the box, and become the carrier of the cargo transportation information. During the transportation, the effective monitoring and real-time management of the cargo status and transportation information are implemented. Once the electronic seal is damaged, it will be reflected to the computer monitoring system.
According to the characteristics of large transportation volume and relatively high value of coal products, Taiyuan Easysoft Technology Co., Ltd. has launched an RFID-based mineral transportation monitoring system, which is suitable for transportation in power plants, smelters, coking plants, coal mines, aluminum plants, mines, etc. Enterprises of mineral products effectively prevent cheating on the replacement, adulteration, and shoddy mineral products during transportation. This system can share the RFID long-distance reader/writer and other infrastructure with the RFID license plate automatic recognition system, saving a lot of investment for the user.
1. System overview
Easy RFID mineral transportation monitoring system adopts RFID electronic seals, which are installed on the door of the transport vehicle. Each RFID electronic seal has a globally unique number. It automatically records the opening time of the door of the car. After the mineral arrives at the destination, it is read and written by RFID. The device automatically reads the cargo transportation information stored in the RFID electronic seal to determine whether cheating has occurred during the transportation process. If there is cheating, the system will automatically alarm. If there is no cheating, the system will automatically unlock, and the RFID electronic seal will be recycled again.
2. System characteristics
safety:The unique electronic serial number (ID) in the world, the length of the ID code is 64 bits (binary), which cannot be changed or copied, and can only be read by a code reader. At the same time, encryption technology is used for the information written in RFID, and only basic data is written. More data is stored in the system database, and the entire system can be considered unbreakable.
Environmental adaptability:RFID is not affected by rain, snow, hail, dust, light, etc., and can complete automatic identification, tracking and management all-weather without contact.
Convenience:Due to the use of long-distance radio frequency identification technology, the inspection procedures are automatically completed by the system, and managers and drivers do not need to get off the car, which is particularly suitable for harsh working environments such as dust, pollution, cold, and heat.
Economical:This system uses RFID electronic seal technology to monitor the opening of the mineral transportation carriage, without real-time monitoring of vehicle operation, greatly reducing construction costs and operating costs, and is particularly suitable for the characteristics of large quantities of minerals and low prices.
Three, system function
Information storage, double anti-counterfeiting: Built-in global unique digital ID, can store the transport vehicle, container number and the detailed information of the loaded goods in the electronic seal, and generate a non-repeatable random code to realize the electronic anti-counterfeiting function, and form a double protection system with mechanical anti-counterfeiting . Combined with a hand-held controller, it realizes temporary inspection and handling of abnormal situations on the way.
Abnormal alarm: Check the lock body status at any time under the monitoring state, and find abnormal situations such as external damage, unauthorized opening, etc., and automatically send an alarm message when the vehicle passes a crossing or weighs.
Logistics monitoring: Support a variety of different mineral transportation supervision business needs through configuration methods.
Four, use process
The electronic seal lock is installed at the switch of the carriage. The method of use is not much different from traditional locks, except that a remote reader is required to seal the lock before shipment.
Locked:At the starting coal mine, coal yard, etc., the driver will lock the lock. At this moment, the electronic seal records the lock time and other information into the RFID.
Starting gate:When the truck reaches the gate of the electric gate, the RFID reader at the departure field automatically reads the information of the electronic seal to see if it is locked. At the same time, the system automatically writes the information of the transport vehicle into the electronic seal RFID and issues an opening instruction. For applications where the starting point is an outside unit, the electronic seal can be checked with the naked eye to see if the electronic seal is closed, eliminating the need for equipment investment at the starting point.
networking:The departure site transmits the cargo information and vehicle information to the monitoring center server through the network. For applications where the origin is an outside unit, this step can be skipped. Entry gate at the terminal: When the truck reaches the electric gate of the terminal or the weighing room, the RFID reader reads the electronic seal information to determine whether the vehicle has cheated during transportation. If it is released normally, make the electronic seal in an openable state, and initialize the electronic seal. If there is any abnormality, the system will automatically alarm.
unlock:The vehicle enters the cargo yard, the manager unlocks, and the electronic seal is recovered for use in the next cycle.
