Description

Device information processing method, device and system based on RFID
Technical Field
The invention relates to the technical field of radio frequency identification, in particular to an equipment information processing method, device and system based on RFID.
Background
An RFID (Radio Frequency Identification ) wireless system, typically having two basic devices, 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 electronic tag records an asset unique identification code EPC (Electronic Product Code ) code, and can store USER-defined data with a certain capacity in a tag USER data area.
In the existing RFID position abnormality alarming technology, an RFID scanner sends RFID tag information to a cloud server for judgment, and then whether an alarm is needed or not is judged according to a returned result.
The cloud server synchronizes the black and white list catalogue of the asset to the internet of things equipment, and the internet of things equipment judges whether an alarm is needed according to the black and white list. Existing asset location records are typically stored using conventional databases, and are individually useful to blockchain technology, requiring the deployment of additional independent blockchain systems.
However, for the existing RFID location transaction alarm technology, usually, a cloud server, such as a fixed asset management system, and an internet of things device are not in a local area network, network access and information return may not be timely, and timeliness may not be guaranteed. For example, it may happen that a person holding an asset with an RFID tag illegally passes through an RFID access control system, and the access control system gives an alarm after 3 seconds have passed, at which time the person has walked away. Meanwhile, in large enterprises such as banks, multiple sites and branch institutions can deploy a large amount of Internet of things equipment, and frequent access causes pressure on a cloud service system. If a black-and-white list mode is adopted, the asset management system needs to synchronize the asset list to the local internet of things equipment frequently, and the internet of things equipment can not process well because the number of the enterprise assets reaches tens of millions.

When the RFID scanner and the gateway equipment read the RFID tag information each time, the RFID scanner and the gateway equipment only need to compare with the position information of the scanner to judge whether an alarm needs to be sent out, and the RFID equipment does not need to access an external network in the process, so that the alarm response speed is higher.
In the following, a specific embodiment will be given by taking a bank as an example, and fig. 6 is a block diagram of the structure of the exemplary system, and as shown in fig. 6, the exemplary system includes: each type of scanner (corresponding to the scanner 1 described above), an RFID gateway (corresponding to the gateway device described above, having the function of the device information processing apparatus 21), and a fixed asset management system (corresponding to the asset management system 3 described above).
Banks have multiple sites/parks nationwide, as shown in fig. 7, each site may have one or more buildings, each building has multiple floors, each floor has one or more rooms, and some of the rooms are warehouses. A somewhat larger room may also have multiple zones divided. There are also racks for blade server class devices, with multiple U-bits on each rack. For each level of location information, there is a unique location code for each park, building, floor, room, area, U-bit.
In the gate of the room of park, building, floor (elevator and corridor), can install entrance guard's RFID scanner, entrance guard's scanner opens there is infrared sensor, can trigger the RFID when detecting that there is the object to pass through. A stationary RFID scanner is installed on the rooftop inside a room, and actively scans the RFID tags in the area according to a predetermined frequency (for example, every 20 seconds) using a polling method. The U-bit level RFID scanning adopts contact or close-range induction scanning.
Generally, the scanner has simple tag scanning, reporting and timing functions, and the entrance guard and the fixed scanner of the embodiment of the invention can be matched with an alarm module. The logic processing of the RFID tag data needs to be performed at the RFID gateway device, which also assumes the management control function of the scanner. If the number of RFID scanners is small, a box gateway can be selected, if the number is large, a rack gateway can be selected, and if more scanners exist, a plurality of RFID gateways can be configured.
The RFID gateway and the affiliated RFID scanner are in the same local area network, so that the response speed is higher. The gateways of all the network sites of the bank are positioned in the internal network of the bank and isolated from the external network. For RFID gateways in different regions, the reliability and speed of the communication between the RFID gateways are lower than those of the internal local area network in the same region.
In general, 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 tag data; (2) The control module of the Internet of things is used for sending instructions such as an alarm to the RFID scanner; (3) And the block chain link point modules are used for forming the decentralised private block chain distributed storage among all the RFID gateways.
Each entrance guard/stationary RFID scanner, when installed, will set the scanner's location information code, which is a list ranging from large to small, for example, as shown in table 1 below: park/dot code-building code-floor code-room code-area code-U-bit code ]:
version number 4 bits Park/dot code 32 bits Building code (16 bit) Floor code (16 bit) Room code (16 bit) Area code (16 bit) U bit code (16 bit)
TABLE 1
Each location information code does not necessarily contain all, e.g., a scanner for a doorway of a building, its location information code is [ park code-building code ]. The scanner can be uniquely identified by position information encoding. Typically, a serial number or MAC address is stored in the blockchain along with the scanner's location information code and the current timestamp. When the scanner location changes, the location information write blockchain needs to be re-registered.
In one embodiment, the RFID scanner information may include: scanner unique identification code, location code, and information of whether the warehouse is in the warehouse.
When a device (also referred to as an asset) is first signed into a warehouse, typically in the warehouse, the asset is labeled with an RFID tag, the tag contents including: EPC unique identification code and USER zone content. Wherein, the USER area content includes: basic information of the device, serial number, status (out of stock, in stock, scrapped), usage range (i.e. limited location range), affiliated departments, etc. 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 encrypted data are obtained and written into the RFID tag. The initial state is set to in-store and the range of use can be set to null.
Fig. 9 is a schematic flow chart of the asset ex-warehouse entry, as shown in fig. 9:
when the asset is delivered out of the warehouse, a manager operates on a terminal page of the asset management system, issues a command to an RFID gateway to which the warehouse access control belongs, wherein the command comprises information for modifying the state of the asset to be in use and information of the use range of the asset, and if the use range is not limited, the use range data is set to be empty; the asset management system stores the encryption private key and encrypts the RFID information.
When the asset passes through the warehouse door, the entrance guard scanner scans and reads the RFID tag information and sends the RFID tag 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 the RFID information of the current asset and checking; 2. writing the encrypted asset state information after the change, 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 access control gives an alarm, repeated operation is needed, or the handheld RFID equipment is used for operation, so that the success of writing the RFID information is ensured.
The RFID gateway also checks the location range data in the RFID tag information, as shown in fig. 10, and the specific procedure includes: 1. checking the state of the asset, and immediately sending an alarm instruction to the corresponding RFID scanner if the asset in the stock state is taken out of the range outside the warehouse; 2. sequentially comparing whether each position range of the RFID tag is within the position information set by the RFID scanner, if not, judging that the asset is out of the use range, and sending an alarm instruction; 3. meanwhile, the RFID gateway also writes the information recorded along with the position of the alarm into a blockchain; 4. the RFID gateway also sends information to an asset management system, the asset management system records the contact information of the current asset user such as a mobile phone and the like, and alarms are notified to the user and an administrator in the form of short messages and the like.
An administrator may query for changes in the location information track of an asset through an asset management system client. The asset management system can access the blockchain, read the position change information of the appointed asset, the position information of the current position, and the like, and can be displayed in the form of a line graph or other User Interfaces (UI).
When the assets are returned and put in storage, an administrator operates in the asset management system, selects the assets and the warehouse to be returned, and sends the encrypted information to the RFID gateway to which the warehouse entrance guard belongs. When the asset enters a warehouse entrance guard, the RFID gateway performs the following processing: 1. acquiring and decrypting the RFID information of the current asset and checking; 2. writing the encrypted asset state information into the RFID tag, and setting the asset state as stock; 3. reading the asset RFID information again confirms that the write was successful.
In actual operation, when an asset attached with an RFID tag is scanned by an RFID scanner (including an entrance guard scanner, a fixed scanner and a U-bit level scanner), the scanner reports RFID information to a gateway, the RFID gateway decrypts check tag data, and then unique identification of the RFID scanner, RFID scanner position information codes, asset unique codes, asset states, time stamps and the like are recorded in a blockchain to be permanently stored as an asset physical position change record.
In the embodiment of the invention, the banking sites are numerous, a large number of RFID gateway devices are required to be deployed, block chain nodes can be directly deployed on the RFID gateway, the response speed is high by combining with the depth of the RFID internet of things, and an additional server is not required. The RFID gateway is positioned in the internal network of the bank, and the private chain can ensure the access processing speed and can also ensure that the RFID gateway is not tampered by internal personnel.
Based on similar inventive concepts, the embodiments of the present invention also provide an RFID-based device information processing method, which is preferably applicable to the device information processing apparatus 21 described above.
