RFID IoT asset management system for public security units

An RFID (Radio Frequency Identification) system consists of two parts: a read/write unit and an electronic transceiver. The reader emits electromagnetic pulses through the antenna, and the transceiver receives these pulses and sends Stored information to the reader in response. In fact, this is the non-contact reading, writing or deletion of data in the memory.

Technically speaking, a "smart label" consists of RFID circuitry including an RFID chip with an RFID radio frequency portion and an ultra-thin antenna loop that is embedded into the tag along with a plastic sheet. Usually, a paper label is glued to this label, and some important information can be clearly printed on the paper label. Current smart labels are generally the size of a credit card. For small goods, there are labels with a size of 4.5×4.5cm, and there are also round labels with a diameter of 4.7cm used on CDs and DVDs.

The advantage of transceiver technology compared to other ID technologies like barcodes or magnetic stripes is the wireless link between reader and transceiver: the read/write unit does not require visual contact with the transceiver and therefore can Fully integrated into the product. This means that the transceiver is suitable for harsh environments and the transceiver is insensitive to moisture, dirt and mechanical influences. Therefore, the transceiver system has very high read reliability, fast data acquisition and, last but not least, saves labor and paper.

System construction background of individual police equipment management system

The Ministry of Public Security promulgated the "Public Security Individual Police Equipment Equipment Standards". In order to strengthen front-line police equipment and improve the police's protective capabilities and combat effectiveness, the Gansu Public Security Department will equip the police with corresponding police equipment according to the work needs of different police types. Individual police equipment is divided into There are two types of "must-have" and "optional" items. Currently, the items required by the Ministry of Public Security mainly include police uniforms, batons, handcuffs, tear gas injectors, bright flashlights, police standard knives and other must-have items, as well as guns, walkie-talkies, There are a total of 15 optional items such as police passes, stab-proof clothing and police equipment bags. If all items are assembled, a single police officer's equipment is worth a lot of money. Since the assembly must be distributed to each police officer, it is difficult to manage it by manual recording or ordinary management Tools.

Overview of single police equipment management system

"Public Security Single Police Equipment Management System" is based on the Internet of Things and uses radio frequency technology electronic tags to identify front-line police equipment. As the ultimate product, electronic tags are not restricted by "cards", and there is also room for development in various shapes and materials. Its products can be divided into three categories: labels, injection molding and cards. The biggest difference between radio frequency technology electronic labels and ordinary barcodes is that barcodes are "visual technology". The scanner works under the guidance of a person and can only receive barcodes within its field of view. In contrast, RFID does not require sight of the target. RF tags can be read as long as they are within the range of the receiver. Bar codes themselves have other disadvantages. If the label is scratched, soiled or peeled off, the scanner cannot read the target. Barcodes can only identify manufacturers and products, but cannot identify specific equipment. The barcodes attached to all the same equipment are the same and cannot provide a complete set of data for the life cycle management of the entire equipment.

Radio frequency technology electronic tags uniformly number each piece of individual police equipment. Real-name distribution is used in the management process. The electronic tag code is a combination of the unique code of the equipment and a randomly generated electronic code. It is the only electronic code for each equipment. Label encoding, with high reliability, security and uniqueness. It fully embodies the standardized management principles of "who is in charge, who is responsible", "whoever handles it, who is responsible", and "whoever uses it, who is responsible";

On the basis of fully studying the business needs of the Public Security Bureau’s equipment management, the “Public Security Equipment Management System” was developed. Use radio frequency technology based electronic tags based on the Internet of Things to complete the daily management and inventory of each equipment, thereby effectively realizing the full tracking of the distribution and usage status of the equipment, and the life cycle management of the equipment. Technically This ensures that the equipment's accounts are consistent to the greatest extent, reduces the intensity of entry work, and thus avoids the repeated purchase or loss of police equipment. Comprehensively improve the equipment management level of the public security department and make police equipment management easier.

3. Fixed ASSET MANAGEMENT system

3.1 Overview of fixed assets system

Fixed asset management is an important part of public security asset management. Fixed assets have the characteristics of large quantity, variety, high value, long service life, and scattered use locations, making management difficult. At present, many public security agencies still rely on manual accounting management methods. Due to the large number of management documents and heavy inventory work, it requires a lot of manpower and material resources. Moreover, the historical operations and asset statistics of fixed assets are extremely difficult, resulting in asset loss and repeated asset purchases. , some asset management software has appeared in recent years. Although it has solved the problem of manual accounting to a large extent, most systems use manual data entry, which is not only slow and error-prone, but also has problems with the physical assets and assets in asset management. The serious problem of accounting disconnection makes it difficult to meet the needs of modern public security asset management.

3.2 Fixed assets system function module

1. Daily management: asset card management, asset entry, asset transfer, asset maintenance, asset borrowing, asset activation, asset deactivation, asset withdrawal

2. Asset inventory: Inventory order inquiry, inventory order entry, profit and loss detailed list, inventory summary

3. Depreciation management: depreciation calculation, monthly depreciation report, annual depreciation report, asset impairment provision, asset value revaluation, accumulated depreciation details

4. Report management: classification detailed statistical reports, department detailed statistical reports, newly added asset statistical reports, exiting asset statistical reports

5. System management: operator/authority, department/personnel information, asset classification code, asset attribute information

6. Label production: label definition, label generation

2.3 Fixed asset system characteristics:

1. The system uses electronic tag technology to achieve effective management of physical assets and eliminate the phenomenon of accounting discrepancies.

2. Apply wireless mobile technology to achieve seamless collection of asset information

3. Provide a powerful data interface and support a variety of external devices.

4. Rich daily management functions make asset tracking simpler and more intuitive.

5. The system is developed using object-oriented technology to realize the separation of data layer, business layer and user presentation layer (user interface), and can be connected to various databases.

2.4 Advantages of fixed asset management system:

1. The system provides powerful label customization functions based on Internet of Things electronic labels. Public security customers can customize the asset label style of their own units.
