Today, with the rapid development of science and technology, all aspects of social life can not be separated from information. The word "information war" has also entered people's eyes. In a military war, speed can determine life and death. In an emergency, the use of vehicles and the understanding of various vehicle conditions may determine the victory or defeat and improve efficiency. Therefore, it is very important to monitor and manage vehicles. The Internet of things industry is developing at a high speed. As one of its main application technologies, RFID technology is also more and more widely used in various fields. There are many cases of RFID application and management of special vehicles. The system uses RFID technology to track and locate military vehicles in the barracks, ensure the logistics management of military modernization, balance the contradiction between supply and demand, and improve management efficiency.
2、 Pain point problem
Military vehicles belong to military vehicles. In an emergency, the deployment of vehicles and the real-time understanding of their own conditions will determine the success or failure and efficiency of the handling of affairs. Therefore, vehicle monitoring and management is so important. At present, the entry and exit of vehicles in the army are all manually registered and monitored by video, or the issued parking permits are used. However, the current management situation can not solve the following problems:
1. The automatic management of vehicles in and out of the warehouse cannot achieve efficient and real-time monitoring;
2. The vehicle braking and starting time cannot be monitored, and the vehicle breaks down without timely assistance;
3. The speed of vehicles in the military compound cannot be monitored, which is easy to trigger accidents;
4. When the vehicle goes out to work or carries out tasks, it is unable to know the prompt of low battery power in time, which leads to failure on the way;
5. In an emergency, the battery voltage of the vehicle is not low, which adds trouble to the emergency;
3、 Function introduction
RFID technology(more info) is fully combined with vehicle management, and RFID technology is applied to the management process of vehicle intelligent parking lot, so as to solve the following problems: 1. The traditional vehicle release mode of parking card swiping greatly improves the vehicle release efficiency and ensures the smooth passage of the entrance and exit of the parking lot; 2. Safety management of vehicles; 3. Master the real-time situation of vehicle starting and acceleration process; 4. Low battery alarm, etc.
1. Automatic vehicle identification
For vehicles in the army, the system can automatically identify and release the brakes. The system saves the basic information of the vehicles in the yard. The database records the license plates, owners and basic information of all vehicles in the garage. When passing through the entrance, the card reader at the entrance recognizes the ID number of the vehicle tag and compares the ID number with the ID number in the database. If the vehicle is in the hospital, the system controls the brake to open automatically. If the vehicle is not in the hospital, the system will give an alarm; The system can control the camera to take pictures of the license plate of the vehicle and save it in the database together with the ID number of the vehicle label.
2. Vehicle start monitoring
When the vehicle receives a task or an outbound command, it needs to brake the vehicle to work smoothly. The system can sense the braking time of the vehicle and the time required for the startup process through the braking sensor, and transmit it to the background database through the communication equipment to record the braking time of the vehicle and the time required for the startup process. When the startup is abnormal, an alarm prompt will occur, and effective measures will be taken in time to avoid delaying the completion of the task on time.
3. Vehicle speed monitoring
When the vehicle is started and in the military compound, there is a certain speed limit. The vehicle acceleration sensor can sense the real-time speed of the vehicle and transmit it to the background. When the speed of the vehicle is abnormal, the system will send an alarm prompt to warn the driver of the vehicle to pay attention to the speed, so as to avoid unnecessary trouble.
4. Battery power monitoring
The battery sensor can monitor the battery power of the vehicle at any time. When the battery of the vehicle is low, an audible and visual alarm will be given to remind the management soldiers to charge in time to avoid delaying the normal operation of the operation. Under normal circumstances, the battery power on the command center screen is green. When the battery voltage of a vehicle is insufficient, the command center frequency screen displays the battery power status of the vehicle as yellow, and gives a sound prompt: the battery of a vehicle in a company is low. Please replace or charge the battery in time; When the battery of a vehicle is completely dead or broken, the command center screen displays the status of the vehicle in red and sends out: the battery of a vehicle is broken (the battery has no voltage), please replace the battery or charge it in time.
5. The brake opens automatically
Identify the license plate. If the license plate display is internal to the army, the system will control the automatic opening of the brake, which saves the administrator from opening the brake one by one. It saves time and also saves the administrator a lot of trouble.
6. Effective vehicle management
For vehicles inside the unit, the system can display whether they are in the hospital. When the vehicle enters the hospital, the system displays that the vehicle is in the hospital; When the vehicle goes out, the card reader at the exit reads the information of the vehicle, and the system displays the position of the vehicle as not in the hospital. With this function, you can count the vehicles in the hospital, and then judge whether the vehicles are in the hospital at any time according to the data in the database.
7. Real time information query
In the command center, the number of vehicles with normal status, pending treatment, battery damage or no power can be queried, which provides convenience for unified dispatching and management.
8. Automatic parking space management
After the system reads the tag information, it automatically assigns an idle parking space to the vehicle, and displays the parking space number of the vehicle on the screen. After that, the vehicle can park the vehicle at the designated parking space.
4、 Construction purpose
1. Improve the informatization level of military vehicle operation and management
The system builds a new mode of information management through the integration of software and hardware. Personalization is used to tailor-made the most matching quality products in combination with the actual management needs of the army.
2. Enhance the level of vehicle safety management

Passive RFID tags are composed of coupling elements and chips. Each RFID has a separate electronic code, which is attached to the object to identify the target object, commonly known as an electronic tag. There are many kinds of electronic labels, each of which has its own characteristics and has its own application market.
The electronic tag can be divided into active electronic tag, passive electronic tag and semi passive electronic tag. The active electronic tag is equipped with a battery, the passive electronic tag does not have an internal battery, and the semi passive electronic tag partially depends on the battery.
Active electronic tag
Active electronic tags are powered by built-in batteries, and different tags use different numbers and shapes of batteries
Advantages: the distance between the passive RFID tag and the RFID reader / writer can reach tens of meters or even hundreds of meters, and the distance can be controlled.
Disadvantages: large volume, high cost, and service time is affected by battery life.
Applications: industry, logistics, real-time traffic management, vehicle access control, etc.
passive tag
The passive electronic tag does not contain batteries, and its power is obtained from the RFID reader / writer. When the passive electronic tag is close to the RFID reader / writer, the antenna of the passive electronic tag converts the received electromagnetic wave energy into electrical energy, activates the chip in the passive RFID tag(more info), and sends the data in the RFID chip.
Advantages: small size, light weight, low cost, long life, can be made into different shapes and applied to different environments.
Disadvantages: since there is no internal power supply, the distance between the passive electronic tag and the RFID reader / writer is affected. Generally, the RFID reader / writer with high power is required.
Application: book management, file management, logistics supply chain management, etc.
Semi active electronic tag
Semi active electronic tag, which integrates the advantages of active electronic tag and passive electronic tag, is a special marker. In normal times, it is in the sleep state and does not work, and does not send RFID signals to the outside. It only starts to work after it enters the range of activation signals and the tag is activated.
Advantages: compared with passive electronic tags. Semi active electronic tags have faster reaction speed and better efficiency. Compared with the active electronic tag, the semi-active electronic tag battery consumes less power.
Disadvantages: large volume and high cost
Application: access control management, object positioning, parking lot management, etc.
OPRFID Technologies' Passive RFID Tags:
NFC developed from contactless radio frequency identification (RFID) and was jointly developed by Philips semiconductor (now NXP semiconductor), Nokia and Sony.
Its foundation is RFID and Internet technology.
NFC works at 13.56MHz, the maximum transmission speed is only 424kbit/s, and the distance of effective data transmission rate is only about 10cm (in fact, the NFC distance between bus card and mobile phone is usually less than 5cm), but its advantage is that it can directly read and exchange data without troublesome pairing process. This can be understood as an interconnection technology, which can "exchange" transmission distance to achieve power consumption and security.
In addition, NFC has excellent pairing speed, less than 0.1ms (which can improve experience and security).
In contrast, Bluetooth takes about 6 seconds and infrared takes about 0.5 seconds.
NFC hardware consists of CLF (non connected front-end module), RF antenna and Se (safety element safety zone).
The clf+ antenna can be used to read the balance of ordinary bus cards, but if the mobile phone / watch is simulated as a bus card (airline card issuance and recharge), the se part needs to be added.
What we see outside is the structure of chip + coil (remove the bus card and flash bank card, which are also the two basic components inside). The coil is usually installed on the back shell or close to the battery. Usually, NFC sensing is carried out through the back of the mobile phone.
Working mode:
Point to point mode: data exchange can be carried out on two devices with NFC function, such as exchanging music, transferring files, etc.
Using this mode requires that both devices have NFC functions, and NFC file transfer is basically an abandoned transfer method.
Because NFC transmission speed is very slow, it is usually only used to transmit a single contact, website and other data and a small amount of information between mobile phones, so there are few daily use scenarios.
Card reader mode: it can be used as a contactless card reader.
It can read or write the information in the electronic tag, but because NFC tag is not widely used in the market, consumers charge the physical bus card through this mode.
However, with the gradual realization of the virtual bus card function, people will rely less on physical bus cards, and the virtual bus card service integrated into mobile phones will be more convenient.
Card emulation mode: in fact, it is equivalent to an IC card using RFID technology.
Mobile phones with NFC function can be used to replace a large number of physical IC cards (bus cards, credit cards, etc.) to realize mobile payment function.

The work to be completed in 2008 includes: the draft standard for 840-845mhz and 920-925mhz frequency tags, the test method for the basic electrical characteristics of 13.56mhz/ RFID tags, the test method for 13.56MHz RFID readers / writers, and the draft standard for the test method for the physical characteristics of RFID tags. As a data carrier, electronic tags can play the role of identification, object tracking and information collection. In foreign countries, electronic labels have been applied in a wide range of fields. The RFID system composed of electronic tag, Handheld RFID Reader, antenna and application software is directly connected with the corresponding management information system. Quick search and positioning of goods: when it is necessary to search for a certain goods, enter the relevant goods information in the handset, and scan the goods within a certain range. When the goods are scanned, the intelligent warehouse management system will send a prompt to facilitate the quick search of the goods.
The application of radio frequency identification (RFID) can fundamentally solve the above problems. Based on radio frequency identification (RFID) technology and according to the actual situation and needs of warehouse management, oprfid technology has developed an RFID intelligent warehouse management system.
RFID is the abbreviation of radio frequency identification, namely radio frequency identification. It is a non-contact automatic identification technology. RFID can be traced back to the Second World War (about 1940). At that time, its main function was to distinguish the enemy from the British aircraft. In recent years, with the development of large-scale integrated circuit, network communication, information security and other technologies, as well as the promotion of Wal Mart, the world's leading retailer, RFID has been rapidly applied to smart grid, transportation, logistics industry, medical health, fine agriculture and animal husbandry, finance and service industry, industry and automatic control, smart home, environment and security detection, public security, national defense, smart city and other industries and fields. UHF Handheld RFID Reader is to automatically identify the target object and obtain relevant data through RF signals. It is mainly composed of electronic tag, reader and antenna. Tags are composed of coupling elements (also known as antennas) and chips. Each tag has an electronic code (EPC), and the chip can store specific serial numbers and other information. The reader is the bridge between the tag and the software system. On the one hand, it reads the tag information, and on the other hand, it communicates the reading results with the software system. The antenna exists in the tag and reader and is responsible for data transmission from the tag chip to the reader and then to the software system.
RFID technology is divided into low frequency, high frequency, ultra-high frequency, active, etc. RFID technology has the characteristics of non-contact, fast scanning, high identification efficiency, not easy to be damaged, suitable for harsh environment, convenient operation, fast reading and writing speed, large amount of information storage, one card multi-purpose, anti-collision, good security encryption performance, reusability, tracking and positioning, etc.
Android Handheld RFID Reader is the single product stage, that is, each product has a dedicated RFID tag. As each product has its own logo, it can realize the minimum unit management of commodities, and play a great role in retail links, anti-counterfeiting, anti-theft, and consumer behavior analysis. It not only increases the number of goods processed in a day, but also monitors all information of goods. Among them, there are various forms of application. Labels can be pasted on goods and read and written by readers on forklifts and at corresponding positions in warehouses; Barcode and electronic label can also be used together. Sales channel management, the establishment of strict and orderly channels, and the efficient management of purchase, sales and inventory are the strong needs of many enterprises. The product is embedded with an electronic label during the production process, which contains a unique product number. The manufacturer can monitor the flow of the product with an identifier. Wholesalers and retailers can identify the legitimacy of the product with a reader provided by the manufacturer. The rapid development of e-commerce, Internet of things and other fields is undoubtedly the driving force of warehousing and logistics. Nowadays, the storage management mode has shown an intelligent trend. RFID technology will greatly improve the level of warehousing and logistics management, and can speed up the information construction of warehousing and logistics management.
By using RFID technology, improve the efficiency of warehouse management and provide the accuracy of WMS system data. The main objectives are as follows:
Reduce human operation leakage, improve management level and reduce potential safety hazards;
Real time data acquisition, keeping the consistency of items and records in time;
Reliable and stable data acquisition and accurate data;
The statements are manually sorted and summarized and then completed by computer;
Improve the efficiency of data management, timely register the detailed accounts of various safety tools and instruments, and achieve the consistency of accounts, materials and cards;
The Android Handheld RFID Reader system is flexible and has expansion function;
The Android Handheld RFID Reader system is practical and easy to operate for users with different levels of professional quality.
However, for most small and medium-sized warehouses, Android Handheld RFID Reader with complete functions and easy operation are generally preferred. There are obvious differences between the two. In the agricultural field, the Internet of things is widely used, such as surface temperature detection, poultry living conditions, crop irrigation monitoring, soil pH change, precipitation, air, wind force, nitrogen concentration, soil pH and land humidity, to make reasonable scientific estimates for farmers in disaster reduction, disaster resistance Scientific planting and other aspects provide great help to improve the comprehensive benefits of agriculture. Intelligent transportation, with image recognition technology as the core, makes comprehensive use of radio frequency technology, tags and other means. All the goods in the warehouse are transferred and stored in pallets. Through the electronization of pallets, the identity of each pallet can be identified, and the real-time tracking of storage and transfer positions can be realized. Combined with the electronic (digital) warehouse location management, it can provide the necessary data foundation for visual and intelligent warehouse management.
