Application of RFID technology in refined oil distribution industry

This program is based on the supply chain of the entire energy industry, and is a research topic for the physical bottom layer of the supply chain and the distribution process of the refined oil distribution company.

RFID system technical support:

The system reader uses a frequency of 13.56 MHz. The readers at this frequency have higher stability, and the price factor has little effect on the system. The hardware components of the reader are mainly single-chip microcomputer, radio frequency chip, antenna, power supply, display circuit and input circuit. The MCU selects AT89S52 MCU from ATMEL. Its I/O port number, EEPROM capacity and support for online programming make many designers choose this chip, which makes the data more complete. The RF chip is selected by PHILIPS' MIFARE 500 chip. This chip is the most powerful chip in the 13.56MHZ band. It supports the communication protocol ISO-14443A. This protocol is safe and simple. Suitable for systems with high security and communication distance is not very far.

The reader controls the radio frequency chip through the single chip microcomputer, generates a high frequency electromagnetic field, drives the antenna, and the power source and the control information act on the passive tag in the range through the spatial coupling mode, and the tag will need the energy after receiving the magnetic field. The returned information is sent back to the reader through the spatial magnetic field to complete the communication.

work process:

(1) At the beginning of the working day, the dispatcher picks up the card a and the mobile storage device from the distribution center, and starts the work to the designated tanker according to the instructions of the administrator. The mobile storage device records the customer list and delivery tasks and driving routes that the dispatcher wants to deliver today. The dispatcher inserts the mobile storage device into the card reader of the designated vehicle, and then reads the card a in front of the car reader. The reader LCD displays the first customer name (customer A) and detailed information. The driver drove to the bus.

(2) At the customer A location, under the premise of soliciting the customer's permission, the delivery staff and the customer simultaneously use their respective cards to swipe the card in front of the car reader. At this time, after the reader confirms, the solenoid valve can be opened and the oil valve is opened. When the customer indicates that the oil can be finished, the solenoid valve is closed, and the information about the amount of oil and the total price of the distribution is recorded on the flow meter. After the dispatcher presses the settlement and prints the document key, the card reader automatically prints out the transaction amount and other information for settlement. The refueling mission was completed.

(3) The delivery staff completes the refueling task on the same day according to the same procedure.

(4) The delivery staff returns to the distribution center with the vehicle, removes the card reader and moves the storage device on the same day, and submits it to the administrator at the same time as the personal card.

(5) The administrator reads the contents of the mobile storage device to the server for storage, and writes a new delivery route and customer list in the mobile storage. Enter the delivery code for the next day for the delivery card, which will only be read by one of all tankers.

(6) Starting from the second working day, the delivery staff received a new card and mobile storage device, read the delivery plan for the day on the designated tanker, and started the new delivery process.

advantage

(1) Data entry for the entire distribution process and settlement process is automatically entered, which greatly improves work efficiency and reduces human error.

(2) Due to the confidentiality of the distribution plan, the delivery staff cannot understand the delivery information of the day before delivery, avoiding possible cheating.

(3) Although it is still impossible to know the total amount of oil in the car, in the settlement process, the customer and the delivery staff must confirm at the same time to complete the refueling process, and the whole process is machine operation, which greatly reduces the false accounting and artificial calculation. The probability of an error occurring.

(4) Since the whole process adopts the electronic storage method, the oil distribution company as the bottom of the supply chain can share data with the upper node company, and can also use GPRS for real-time data transmission if necessary. Such a highly transparent supply chain maximizes its effectiveness and is very helpful in reducing inventory.

Animal Food Safety Traceability System Solution Based on RFID Technology

The animal food safety traceability system includes many links from “farm” to “consumer”, including: farms, transportation logistics, slaughterhouses, logistics and warehousing, supermarkets and consumers.

After the farm animals are born, the farm management platform generates a unique “production identification code” and registers the information in the food safety data center to establish a database of individual animal information. The batch, feed, immunization, quarantine and other conditions of the livestock during the feeding process are recorded in the food safety data center through the management platform.

The basic information and logistics of the logistics enterprise are registered in the food safety data center through the logistics transportation management platform. At this point, the RFID tag of the breeding link can still be used as the unique identifier for management.

The slaughterhouse can monitor the production process according to the identification of the livestock, and each link is registered in the data center through the slaughterhouse management platform. The livestock in the slaughterhouse were slaughtered and divided. The pre-segment management platform reads the “production identification code” of the meat to be segmented, and generates a plurality of “slaughter identification codes” according to the quantity to be divided, and each slaughter identification code corresponds to the corresponding segmentation part.

Through the management platform, the basic information of logistics, basic information of storage, logistics temperature of multiple time nodes, storage temperature and other information are summarized to the information center to realize the individualized process management of animal food in the logistics and storage.

Meat in the supermarket is continued to be split. The supermarket management platform reads the “slaughter identification code” of the organic RFID tag identification, and automatically generates a plurality of identification codes according to the division. The “user identification code” and “slaughter identification code” are registered in the data center and a corresponding relationship is established. The “User Identification Code” is marked on the label. The number of “user identification codes” is very large and can only be used with 2D barcodes or organic RFID tags.

The consumer can query the “user identification code” of the product through the public inquiry system according to the user’s two-dimensional barcode or organic RFID tag provided by the supermarket. Then query the information of the supermarket and trace back to the “slaughter identification code”. Learn about meat transportation, warehousing information, production information in slaughterhouses, and can be traced back to the “production identification code” of meat. The “production identification code” can be used to query the transportation and sales information of the livestock, the information of the feeding link, and the like. Consumers can trace the entire meat production process from the end product.

According to the characteristics of each link and its requirements for label technology, organic RFID is expected to replace inorganic RFID in slaughterhouses and transportation warehousing. For animals with shorter breeding time, organic RFID can also be used in breeding and logistics transportation. Organic RFID or two-dimensional labels are available for use in supermarkets. The use of organic RFID will greatly reduce the cost of animal food traceability, thereby promoting the widespread use of animal food traceability technology.

Detailed design of the RFID-based smart hotel system

In the hotel VIP customer service system, the RFID tag is used to identify the current location of the customer, and the other application system is provided with a trigger signal to correlate the relevant information of the customer.

The normal operation of RFID equipment is a prerequisite for the automatic operation of other systems. The operation status and failure of RFID equipment require the attention of hotel management personnel.

In the system software, the RFID device management module displays the operating status of the RFID device in a friendly and clear manner through a professional HMI interface. When the device malfunctions or runs abnormally, the system software will issue an alarm at the first time to notify the hotel management. The personnel timely confirm and eliminate the faults to ensure the safe and stable operation of the entire hotel service system.

The system realizes the information exchange and management with the RFID hardware through design and development of the communication interface with the RFID system, and completes the information exchange with the upper application system.

Smart Hotel consists of three systems: VIP to store reminder, floor navigation, and banquet/conference management.

Each subsystem uses the basic structure of RFID as the basis of information. When the card information is recognized, the card reader transmits the card information to the background through the network, and compares the data in the database to obtain the relevant information of the corresponding guest or asset. Then, by querying the number of the card reader in the database, the location where the card is recognized can be obtained, and then the related service prompt information is generated, or the management operation prompt is generated, and the application generated based on the different information is the subsystems. The different features offered.

Vital Applications and Advantages Of RFID Technology

Why is our express delivery always accurate on the route? Why are the books in the school library managed neatly and orderly? Why are some accidentally stolen items quickly tracked back? These have to use RFID technology.

There are two situations in which RFID technology works. One is to receive the RF signal from the reader when the RFID tag enters the effective recognition range of the reader. The energy obtained by the induced current is used to send the information stored in the chip. The RFID tag actively transmits a signal of a certain frequency, and the reader receives the information and decodes it, and sends it to the central information system for data processing.

There are three main categories of RFID technology products:

1. Passive RFID products:

Such products require close-contact identification, such as meal cards, bank cards, bus cards and ID cards. These card types require close contact during work identification. The main working frequencies are low frequency 125KHZ and high frequency 13.56MHZ. UHF 433MHZ and 915MHZ. These products are also common in our lives and are relatively early in development.

2. Active RFID products:

This type of product has the characteristics of automatic identification over long distances, so it is applied to some large-scale environments, such as smart parking lots, smart cities, smart transportation and Internet of Things. Their main work is microwave 2.45GHZ and 5.8GHZ. , UHF 433MHZ.

3. Semi-active RFID products:

As the name suggests, it is the combination of active RFID products and passive RFID products. It combines the advantages of both, and enables the microwave

2.45G to take advantage of the low frequency 125KHZ frequency to solve the problem that active RFID products and passive RFID products cannot solve. Problems such as access control, area location management, and security alarms, proximity positioning, and long-distance transmission of data.

RFID technology application

1. Warehouse / Transportation / Materials:

The RFID chip is embedded in the goods, stored in warehouses, shopping malls and other goods as well as in the logistics process. The goods related information is automatically collected by the reader, and the management personnel can quickly inquire the goods information in the system, reduce the risk of being discarded or stolen, and improve the goods. Hand over speed, improve accuracy, and prevent stocking and anti-counterfeiting.

2. Access control / attendance:

Some companies or some large conferences can identify the sign-on through the door identification system by entering the identity or fingerprint information in advance, which saves a lot of time, convenient and labor-saving.

3. Fixed asset management:

Some places, such as libraries, art galleries, and museums, where assets are large or expensive, require complete management procedures or rigorous protection measures. When the information stored in books or valuables changes abnormally, it will be in the system for the first time. Remind the administrator to handle the situation.

4. Train / car identification / baggage security:

The railway dispatching system of China's railway is a typical case, which automatically identifies the vehicle number and information input, saves a lot of manual statistics, and improves the accuracy.

5. Medical information tracking:

Case tracking, waste tracking, and drug tracking are all good ways to improve hospital service levels and efficiency.

6. Military/Defense/National Security:

The dynamics of some important military drugs, guns, ammunition or military vehicles require real-time tracking.

Seven advantages

1. Strong anti-interference

Non-contact identification, able to work in a harsh environment, with strong penetrating power, can quickly identify and read labels.

2. The data capacity is very large

It can be expanded to 10k according to the user's needs, much higher than the 2,725-digit capacity of the two-dimensional bar.

3. Can be operated dynamically

Its tag data can be dynamically modified by programming and can be dynamically tracked and monitored as long as the object to which the RFID tag is attached appears within the effective recognition range of the reader.

4. Long service life

Because of its strong anti-interference, RFID tags are not easily damaged and have a long service life.

5. Anti-collision

It can read multiple RFID tags simultaneously within the effective recognition range of the reader.

6. High security

The RFID tag can be attached to the product in any form, and the tag data can be password encrypted to improve security.

7. Recognition speed is fast

As soon as the RFID tag enters the valid recognition range of the reader, the data is immediately read, and in general, the identification can be completed in less than 100 milliseconds.
