Technical Field
The invention relates to the technical field of radio frequency identification, in particular to a method, a device and a system for processing equipment information based on RFID.
Background
An RFID (Radio Frequency Identification) wireless system, typically having two basic components, an RFID scanner and an RFID tag, is used to detect and track objects. The system consists of one or more RFID scanners and a plurality of RFID tags. The RFID tag records an asset unique identification Code EPC (Electronic Product Code) Code and can store a certain amount of USER-defined data in a tag USER data area.
In the existing RFID position transaction alarm technology, an RFID scanner sends RFID label information to a cloud server for judgment, and then whether alarm is needed or not is judged according to a returned result.
The other mode is that the cloud server synchronizes the black and white list directory of the assets to the internet of things equipment, and the internet of things equipment judges whether to alarm according to the black and white list. Existing asset location records are typically stored using conventional databases, individual utility to blockchain techniques, requiring the deployment of additional independent blockchain systems.
However, for the existing RFID location transaction alarm technology, a cloud server, such as a fixed asset management system, and an internet of things device are not in a local area network, and network access and information return may not be timely, so that timeliness cannot be guaranteed. For example, it may happen that a person carrying an RFID-tagged asset illegally passes through an RFID access system, and the access gives an alarm after 3 seconds, at which point the person has gone far away. Meanwhile, in a large enterprise such as a bank, a lot of internet of things devices can be deployed at network points and branch institutions, and frequent access causes pressure on a cloud service system. If a black and white list mode is adopted, the asset list needs to be synchronized to the local internet of things equipment frequently by the asset management system, and the internet of things equipment cannot be well processed because the number of enterprise assets reaches the level of ten million.

According to the embodiment of the invention, the self-defined data area of the RFID label is utilized to record the equipment state information and the limited position information into the RFID label, and meanwhile, the RFID scanner can record the self position information. When the RFID scanner and the gateway equipment read the RFID label information each time, only the comparison with the position information of the scanner is needed to judge whether the alarm needs to be sent or not, and the RFID equipment does not need to access an external network in the process, so that the alarm response speed is high.
A specific embodiment is given below by taking a bank as an example, fig. 6 is a block diagram of the structure of the example system, and as shown in fig. 6, the example system includes: various types of scanners (corresponding to the scanner 1 described above), RFID gateways (corresponding to the gateway devices described above, having the function of the device information processing apparatus 21), and fixed asset management systems (corresponding to the asset management system 3 described above).
A bank has a plurality of sites/parks nationwide, and as shown in fig. 7, each site may have one or more buildings, each of which has a plurality of floors, each of which has one or more rooms, wherein some of the rooms are warehouses. A larger room may be divided into multiple zones. There will also be racks for blade server class devices, with multiple U-bits per rack. For each level of location information, there is a unique location code for each campus, building, floor, room, area, U bit.
An entrance guard type RFID scanner can be installed at the door openings of rooms of a park, a building and floors (elevators and corridors), an infrared sensor is opened in the entrance guard type RFID scanner, and when an object is detected to pass through, RFID scanning can be triggered. A stationary RFID scanner is installed on the roof of the room, and the stationary scanner actively scans the RFID tags in the area according to a predetermined frequency (e.g., every 20 seconds) in a polling manner. The U-bit RFID scanning adopts contact or close-range induction type scanning.
Generally speaking, the scanner has simple label scanning, reporting and timing functions, and the entrance guard and the fixed scanner in the embodiment of the invention can also be selectively provided with alarm modules. The logic processing of the RFID label data needs to be carried out at the RFID gateway device, and the RFID gateway also plays a role in the management and control of the scanner. If the number of the RFID scanners is small, a box type gateway can be selected, if the number of the RFID scanners is large, a rack type gateway can be selected, and if more scanners are available, a plurality of RFID gateways can be configured.
The RFID gateway and the RFID scanner are in the same local area network, so that the response speed is high. The gateways of all the outlets of the bank are in the internal network of the bank and isolated from the external network. For RFID gateways in different regions, the reliability and the speed of communication among the RFID gateways are lower than those of the local area network in the same region.
Generally, the RFID gateway itself is a high performance computer, and as shown in fig. 8, the RFID gateway device mainly includes 3 modules: (1) the decryption verification module is used for decrypting and verifying the RFID label data; (2) the Internet of things control module is used for sending instructions such as an alarm to the RFID scanner; (3) and the block chain link point module and all the RFID gateways form decentralized private block chain distributed storage.
Each entrance guard/fixed RFID scanner, when installed, sets the position information code of the scanner, which is a list ranging from large to small, for example, as shown in table 1 below: [ campus/grid coding-building coding-floor coding-room coding-area coding-U bit coding ]:
version number 4 bit Park/mesh point code 32 bit Building code (16 bit) Floor code (16 bit) Room code (16 bit) Region code (16 bit) U bit code (16 bit)
TABLE 1
Each location information code does not necessarily contain all, for example, a scanner of a building doorway whose location information is coded as a campus code-building code. The scanner can be uniquely identified by position information encoding. Typically, the serial number or MAC address, along with the scanner's position information encoding, and the current timestamp, are stored in the block chain. When the scanner position is changed, the position information writing block chain needs to be registered again.
In one embodiment, the RFID scanner information may include: scanner unique identification code, location code, and information whether it is in the warehouse.
When a device (also referred to as an asset) first signs into a warehouse, typically in the warehouse, the asset is tagged with an RFID tag, the tag contents including: EPC unique identification code and USER zone content. Wherein, the USER area content comprises: basic information of the equipment, serial numbers, states (ex-warehouse, in-warehouse and scrapped), use ranges (namely limited position ranges), departments to which the equipment belongs and the like. The tag USER information is encrypted through a private key, the encrypted private key is stored in an asset management system, the handheld scanner is communicated with the asset management system, and the encrypted data is obtained and written into the RFID tag. The initial state is set to be in the library and the usage scope may be set to be empty.
Fig. 9 is a schematic flow chart of the assets warehousing and ex-warehouse, as shown in fig. 9:
when the assets are delivered from the warehouse, a manager operates on a terminal page of the asset management system and issues an instruction to an RFID gateway to which the warehouse access control belongs, wherein the instruction comprises information that the state of the assets is modified to be in use and the use range of the assets, and if the use range is not limited, the use range data is set to be null; the asset management system stores the encrypted private key and encrypts the RFID information.
When the assets pass through the warehouse door, the entrance guard scanner scans and reads the RFID label information and uploads the RFID label information to the RFID gateway, and the RFID gateway is preset with a decrypted public key. The RFID gateway performs the following processing: 1. decrypting and verifying the RFID information of the current asset; 2. writing in the changed encrypted asset state information, and setting the asset state as in use; 3. reading the asset RFID information again confirms that the write was successful. If the processing is interrupted, the entrance guard can send an alarm and needs to operate repeatedly or operate by using handheld RFID equipment, so that the writing of the RFID information is ensured to be successful.
The RFID gateway also checks the location range data in the RFID tag information, as shown in fig. 10, the specific process includes: 1. checking the asset state, and if the assets in the stock state are taken out of the range outside the warehouse, immediately sending an alarm instruction to the corresponding RFID scanner; 2. sequentially comparing whether each position range of the RFID label is in the position information set by the RFID scanner, if not, judging that the asset is beyond the use range, and sending an alarm instruction; 3. meanwhile, the RFID gateway can write the alarm into the block chain along with the position recording information; 4. the RFID gateway also sends information to an asset management system, the asset management system records the contact way of the current user of the asset, such as a mobile phone, and the like, and informs users and managers of the alarm in the form of short messages and the like.
The administrator can inquire the position information track change of the assets through the asset management system client. The asset management system may access the block chain, read the location change information of the specified asset, the current location information, and the like, and may be presented in the form of a line graph or other UI (User Interface).
When the assets are returned and put in storage, the administrator operates in the asset management system, selects the assets and the warehouses to be returned, and sends the encrypted information to the RFID gateway to which the warehouse entrance guard belongs.
