1. the tag based on Internet of things technologies introduced
1.1 basic definition: electronic label known as RFID, transponder, data carriers; reader, also known as readout devices, scanners, read-head, Communications Manager, reader (depending on whether the tag wirelessly overwrite data). RFID tag and reader of RF signals through coupling element between spaces (non-contact) coupling; coupling channel, according to the temporal relations, realize energy transmission and data exchange.
1.2 operating frequency: -125KHZ;-13.56MHz; -915MHz; -2.45GHz;-5.8GHz
1.3 part: most basic of electronic label system by three part composition: label (Tag): by coupled components and the chip composition, each label has only of electronic coding, high capacity electronic label has user can writes of storage space, attached in objects Shang identifies target object; reading device (Reader): read (sometimes also can writes) label information of equipment, can design for handheld type or fixed type; antenna (Antenna): in label and read device between passed RF signal.
1.4 features: data storage: compared with traditional forms of labelling, greater capacity (1bit-1024bit), data can be updated at any time, read/write. Read and write speed: compared with the bar code without line alignment scan, read and write faster, target recognition, motion recognition. Easy to use: small volume, easy to package, can be embedded within the product. Security: chip, serial number only, it's hard to copy. Durable: mechanical fault-free, long life and resistance to harsh environments.
1.5 system infrastructure looks like this:
When equipped with electronic tags in the distance 0~10 meters when they approach the reader, reader-controlled microwave queries issued signals installed on the surface of the equipment e-label reader queries received signal, this signal and data information is incorporated in the label reflecting back
1.6 working principle:
RFID technology of basic work principle does not complex: label into magnetic field Hou, received interpretation device issued of RF signal, with induced current by get of energy sent out storage in chip in the of products information (PassiveTag, no source label or passive label), or active sent a a frequency of signal (ActiveTag, has source label or active label); interpretation device read information and decoding Hou, sent to central information system for about data processing.
RFID (radio frequency identification) system consists of two parts: a read/write unit and electrical transceiver. Reader antenna emits electromagnetic pulse, the transceiver receives the pulses and send the information you have stored to reader response. In fact, this is a non-contact data to memory read, write, or delete.
Technically, the "smart label" includes include RFID radio frequency part and an ultra-thin RFID chips RFID circuit of the antenna loop, the antenna and a plastic sheet with embed tags. Typically, sticking a label on this label, on a paper label can be printed clearly on some important information. Current smart tags generally credit card size, for small cargo as well as 4.5x4.5cm size of labels, also have CD and DVD with a diameter of 4.7 cm round labels.
As compared to other ID technologies such as bar codes or magnetic strips, transceiver technology has the advantage of readers between transceiver and wireless link: read/write unit without visual contact between the transceiver, so it can be fully integrated into the product. This means that the transceiver is suitable for harsh environments, the transceiver not sensitive to damp, dirty and mechanical influences. Therefore, the transceiver system with a very high reading reliability, fast data access, the last point is the important thing is to save  
Of the public order police equipment management system based on the Internet of things RFID electronic tags to identify police equipment, as the ultimate product electronic label from "restriction", form the material also has a variety of room to manoeuvre. Their products can be divided into Label class, injection molding and cards such as three categories. RFID electronic tags and the common barcode, barcode is the biggest difference between the two is the "Visual Technology" scanners under the guidance of the people, can only receive the bar code within its field of vision. By contrast, RFID does not require the target. RFID tags within the scope as long as the receiver can be read. Barcode itself also has other disadvantages, if the labels are cut, contamination or loss, scanner is unable to identify the target. Barcodes can only identify the producer and the product does not identify specific equipment, put in all the same equipment bar codes are the same, not for the entire equipment lifecycle management providing a range of data.
RFID electronic label number on every single police equipment, management process uses the real-name system for dispensing, electronic tag encoded to be equipment specific to coding and electronic code combination becomes of randomly generated, unique tags for each equipment code is, with high reliability, security, and uniqueness. Fully reflected in accordance with "who's in charge and who is responsible for", "who handled, and who is responsible for" and "who uses, who is in charge of" standardization of management principles;
British mega-company business needs sufficient research Bureau equipment management on the basis of the public security management system was developed. Based on the Internet of things RFID electronic tags to complete for each equipment daily management and inventory work, thereby efficiently enables the equipment%
Electronic label system provides a powerful synthesis of functional,
Collection terminals for data collection and inventory of equipment assets accurately and efficiently
Realize the single police equipment used in the life cycle of process monitoring and tracking
Powerful data import and export functions to facilitate data exchange with other systems and docking.
3. fixed assets management system
2.1 fixed assets system overview
Fixed asset management is an important part of public security asset management, fixed assets with large quantity, variety, variety, high value, long cycles, scattered and other characteristics, management is difficult. Currently, many police organ still rely on manual accounting of management way, due to management documents many, and inventory work heavy, needed occupied large of human material, and fixed assets of history operation and assets statistics work exception difficult, led to assets loss and assets repeat acquisition, in recent years appeared has some assets management software, although in is big degree Shang solution has manual accounting of problem, but most system used manual way entry data, not only speed slow, and easy produced errors, And asset management assets in physical touch with the accounts of serious problems, it is difficult to meet the needs of modern public security asset management.
2.2 fixed assets system module
1, daily management: for card management, asset entry, transfer of assets, asset maintenance, capital borrowing, asset enabling, deactivate, asset out
2, asset inventory: the inventory query schedule of single entry, profit loss, inventory, inventory summary
3, depreciation management: annual report monthly depreciation, depreciation, depreciation, impairment of assets, asset value revaluation, depreciation detail
4, report management: classification detail detailed statistical reports statistical reports, sector statistics, new assets. 
1, the system using RFID technology, realizing the effective management of assets in kind, put an end to the phenomena of inconsistent accounts.
2, the application of wireless mobile technology, asset information seamlessly collect
3, provides powerful data interface, supports a variety of external devices.
4, daily management functions, make asset tracking more simple and intuitive
5, the system based on object-oriented technology development, data tier, business tier, the user presentation layer (user interface) of separation, can hook a variety of databases.
2.4 fixed assets management system benefits:
1, the system provides Internet based electronic label, powerful label customization capabilities, customers can customize their own units of public security asset tags style.
2, supports different modes of electronic label, meet the orderly management of property assets.
3, the use of data acquisition and asset inventory data reader terminals accurately and efficiently.
4, realizing on the assets the physical life cycle of process monitoring and tracking
5, powerful data import and export features for easy data exchange with other systems and docking.
