RFID Technology Provides Strong Guarantee For Army Asset Management

Modern warehousing and logistics distribution have become more diversified and demanding. Not only must we implement the storage management of goods, but we must also mark the types, quantities, attributes, etc. of goods in the warehouse one by one. Especially in the management of military supplies, high standards and strict requirements are even more needed. RFID technology relies on many characteristics and has been maturely applied in various fields to efficiently improve internal inventory, warehouse positioning, and distribution security control management.

The army material RFID management system is an Internet of Things solution for military weapons, firearms, combat readiness, and other types of material management. Among them, RFID access control system, material management system, alarm system and other systems are combined into one, which not only manages combat preparation materials, but also realizes management of other property materials in the army, personnel authority management, material life cycle management, and maintenance. Reminders and other functions provide favorable guarantees for the management of many materials in the army.

Deploy and install RFID access control systems in the warehouse of combat readiness materials or training materials, and install RFID access doors or RFID reader devices in the warehouses to identify the access to the access channels. First, you need to apply in advance to the reserve materials administrator (the reserve materials administrator only has access to the access control system). All combat materials are equipped with unique electronic ID RFID tags, and the information about the combat materials corresponding to the tags is recorded in the system. At the same time, each person who enters the warehouse to extract strategic materials is equipped with an RFID card with its identity information. After the materials are extracted and passed through the RFID access door, the personnel information and the material information raised by the person will be obtained. Relevant records of personnel information, the system will prompt the successful borrowing of the material. When returning the materials, the system will also record the relevant information of the personnel and materials when passing through the RFID access door to ensure that the materials can be put into the warehouse in time. The material management personnel will use the RFID handheld terminal device. Inventory inspection of the material situation, the inspection situation information is recorded in the system to facilitate the daily maintenance and management of materials.

Intelligent warehouse management with RFID technology can enhance the accuracy and speed of warehouse operations. Reducing the loss of individual assets due to inadequate management in the inflow and outflow of combat readiness materials, laying a foundation for ensuring the security of combat readiness materials. Improve the management and service level of the combat readiness warehouse, and provide favorable guarantees for the work of the army's logistics department, equipment department, and training department. RFID technology combined with network technology to build military asset management to achieve modernization and informationization, and provide intelligent security management for combat readiness and storage.

UHF RFID Electronic Tags

UHF RFID electronic tags usually refer to electronic tags that conform to the ISO18000-6C & EPC C1G2 protocol. Of course, there are also electronic tags of the ISO18000-6B protocol, but the ISO18000-6B protocol is gradually marginalized.

First, what needs to be considered is the storage structure of UHF electronic tags?

1. What is the model of the chip?

2. What is the memory map of the chip in the chip's specification?
Generally, the electronic label of the 6C protocol is divided into a TID area, an EPC area, a user area, and a reserved area. The TID is the serial number of the solidified chip and cannot be changed. The EPC area is the most frequently used and written area. Some tags have a user area, and some tags, except for the user area, are usually reserved for storing access passwords.

What kind of data do we need to store in UHF RFID electronic tags? Does the data need to be encrypted?

A typical case is the coding method used in the RFID clothing industry.

96 bit EPC, can store 24 HEX in total, how to allocate these 24 HEX is more important, the following figure clearly lists the storage type of a certain garment,

1- 14 for the product UPC
15-19 digits for clothing information such as style, color, size

20--24 digits are the serial number

Access password and inactivation killing password, add according to your own needs, but you need to pay attention to whether the chip itself can perform password operations

Finally, prepare the UHF RFID reader for batch writing.

Indian Company Simplifies Solid Waste Management with RFID Tags

Indian company Agra Nagar Nigam has decided to simplify solid waste management by installing RFID tags, which are installed in 99,450 houses in 51 communities and handing over 350 RFID handheld readers to cleaners.

Homeowners must put dry garbage and wet garbage in different bins and pay a Rs 65 management fee each month.

When the cleaner collects garbage from the house and scans the RFID tag installed in the house, it will automatically signal to the command and control center of the Agra Smart City Office. After collecting garbage, the homeowner will receive a text message from the mobile phone.

If cleaners do not collect garbage at home, homeowners can also complain through mobile apps.

Homeowners must keep the RFID tags intact. If there is a problem with the label, the homeowner will pay a fine of Rs 100 for this.

The collected garbage will be sent to six collection centers located at different locations in the city. The dry waste is then sent to the processing plant and the wet waste is sent to the composting plant.

What is the difference between a barcode and an RFID tag? What are the types of RFID tags?

Bar codes and RFID tags are both item information identification technologies, and their essence is to give a special number to an item, through which you can get information about the item.

The bar code is numbered by knowing the change of the image by optical means.

The RFID tag can be considered as the electronic version of the barcode, and its working principle is the radio principle. The number information in the RFID tag chip is obtained through the process of electromagnetic wave carrier and modulation.

RFID tag category:
Low-frequency electronic tags:
Its operating frequency range is 30kHz ~ 300kHz.

Typical operating frequencies are: 125KHz, 133KHz (There are other frequencies close to it, such as TI uses 134.2KHz).

High and medium frequency electronic tags:

The working frequency of mid-to-high frequency electronic tags is generally 3MHz ~ 30MHz. Typical operating frequency is 13.56MHz.

UHF and microwave tags:
Ultra-high frequency electronic tag, its typical working frequency is: 433.92MHz, 862 (902) ~ 928MHz;
Microwave range: above 3GHz

Ultra-high frequency (UHF) ranges from 300MHz to 3GHz, and microwave ranges above 3GHz. RFID systems using UHF and microwave are called UHF RFID systems. Typical operating frequencies are 433MHz, 860 ~ 960MHz, 2.45GHz, 5.8GHz, and the frequency wavelength is around 30cm.

UHF tags can be active or passive, and communicate with the reader through electromagnetic coupling. The communication distance is generally greater than 1m, typically 4-6m, and the maximum can exceed 10m.

Radio waves in the UHF band cannot pass through many materials, especially suspended particulate matter such as water, dust, and fog.

UHF readers have very high data transfer rates and can read a large number of electronic tags in a short period of time.

The reader is generally equipped with a directional antenna, and only tags within the directional wave speed range of the reader antenna can be read and written.

The antenna inside the tag is long and label-like. The antenna has two designs, linear and circular polarization, to meet the needs of different applications.

The data storage capacity of UHF tags is generally limited to 2048bit.

From a technical and application perspective, tags are not suitable as a carrier of large amounts of data. Their main function is to identify items and complete the non-contact identification process. Typical data capacity indicators are 1024bit, 128bit, 64bit, etc.

Typical applications include supply chain management, production line automation, air parcel management, container management, railway parcel management, and logistics management systems.

RFID Technology Solves the Problem of Fixed Asset Inventory

The three major problems facing fixed asset management, long inventory cycle, scattered assets, inconsistent accounts and asset numbers, etc.

An UHF RFID system consists of three main parts, the control system, responsible for the issuance of all control commands, the operation of the business and the final data acquisition, analysis and storage. After receiving the instruction, the UHF RFID Reader wirelessly interacts with the electronic RFID tag to complete the data. The RFID label is an identification system that identifies the identity information of the materials, so that the system can track and manage the material information through the identification of the electronic labels.

Based on RFID technology, asset data is stored in tags or systems as needed to achieve full lifecycle management of asset purchase, use, maintenance, inventory, and scrapping, real-time monitoring and management of important assets. To achieve consistent accounting, greatly improve the efficiency of asset inventory and asset utilization.

Classification and characteristics of RFID middleware

Looking at the current variety of RFID applications, the first question companies want to ask is: "How do I connect existing systems to these new RFID readers?" The essence of the problem is the problem of enterprise applications and hardware interfaces. Therefore, permeability is the key to the entire application. Properly capturing data, ensuring the reliability of data reads and efficiently transferring data to back-end systems are issues that must be considered. The traditional application and application data transparency is solved through the middleware architecture, and various Application Server applications are developed. Similarly, middleware architecture design solutions are also an integral part of RFID applications. A very important core technology.

RFID middleware acts as an intermediary between RFID tags and applications. A set of general purpose application programming interfaces (APIs) provided by the middleware on the application side can be connected to the RFID reader to read the RFID tag data. Thus, even if the database software or the back-end application storing the RFID tag information is replaced or replaced by another software, or the type of the read-write RFID reader/writer is increased, the application side is not required to be modified, and many-to-many connection maintenance is omitted.

RFID middleware is a message-oriented middleware (MOM). Information is transmitted from one program to another in the form of a message. Information can be transmitted asynchronously, so the sender does not have to wait for a response. Message-oriented middleware not only includes the ability to communicate information, but also the ability to interpret data, security, data broadcasts, error recovery, locate network resources, find cost-compliant paths, determine messages and prioritize extensions, and debug extended services. 

RFID middleware can be divided into two types from architecture:
Application-centric (Application Centric)
Use the API provided by the RFID Reader vendor to directly write the Adapter of a specific Reader to read the data in the Hot Code mode and transfer it to the application or database. The backend system implements the purpose of the backend system or service connection.

Architecture-centric (Infrastructure Centric)
With the increasing complexity of enterprise application systems, enterprises can not load Adapter for each application in HotCode mode, and at the same time face the problem of object standardization, enterprises can consider the RFID middleware of the standard specifications provided by the manufacturer. In this way, even if the database software storing the RFID tag information is replaced by another software, or the type of the RFID reader that reads and writes the RFID tag is increased, the application side can cope without modification.
