3. Industry demand analysis
Informationization is a key factor for enterprises to promote rapid business growth and improvement. At present, the backwardness and lack of informatization means the lack of an enterprise as a whole, and vice versa. The demand for business informatization of enterprises is very urgent, and warehouse management is one of the very important links.
There are many definitions of inventory and inventory management. Some people think that inventory refers to the reserve of all resources of an enterprise, and the inventory system refers to a whole set of systems and control methods used to control inventory levels, time and order quantities. However, no matter how it is defined, if there is no efficient warehouse management business processing (such as daily work such as outgoing, warehousing, inventory counting, etc.), and no accurate and timely processing of information, the company’s inventory business operations will cost a lot of manpower, material resources, and time. , Resulting in a waste of resources in all aspects. Common problems existing in traditional warehouse management:
a) Without the use of barcode and RFID management methods, it is difficult for warehouse management to match the booked quantity with the physical quantity.
b) Warehouse management staff has a heavy workload, high work intensity, slow speed and low efficiency;
c) If manual data recording is used, the probability of error is high;
d) All kinds of warehouse operation data are recorded in various ledgers, which makes it inconvenient to query statistics;
e) Without accurate real-time data, the accuracy of procurement plan management is not predictable.
According to relevant information, the RFID market is currently undergoing rapid development and changes. The development of China and the global RFID market is in full swing, and the market is facing a full start and explosion. Before the large-scale launch of the market, the policies, standards, industrial chain structure and competition situation are extremely complicated and still face many variables. The only thing the industry companies can control and actively prepare for external factors is the research and analysis of user needs. Through in-depth understanding of user needs, they can provide targeted RFID application solutions for industry customers. Little bee conducts research and summary analysis of the needs of different industries and different customers. Listed below are several customer requirements information:
1) A company in the medical industry is providing medical equipment for hospitals. It hopes to solve the problem of inventory management through the RFID warehouse management system. The main reason is to make it more convenient to find drugs and to solve the problem of drug management confusion. The existing method is electronic shelves, but it does not meet the requirements of customers. Now I hope that a company will cooperate with them to provide a more complete solution for multiple hospitals.
2) A construction company wants to manage three warehouses, the three warehouses are next to each other, more than 10,000 square meters, and there is a storage yard. It used to be completely manual operation, but now I want to build a warehouse management system and connect it with the financial aspects of ERP software. The main purpose is to save manpower, facilitate inventory management, and use RFID or barcode for management to achieve property matching and reduce losses.
3) A certain company has a warehouse of more than 30,000 square meters, with a daily shipment volume of dozens of tons. In the past, it was managed by barcodes, which was easy to be lost and damaged, and the inventory could not be displayed in real time. Want to manage through RFID.
We have found that customers expect the software and hardware systems based on RFID technology to be more closely integrated, the recognition rate of RFID can reach 100%, and the recognition distance is 3-5 meters. Customers will not care too much about the system architecture and the specific implementation of the technology. They are more concerned about the amount of investment and what functions are implemented, and at the same time, they can solve their concerns and truly achieve a higher return on investment.
Fourth, RFID advantage analysis
As the core technology of the Internet of Things, RFID is also the most widely used in warehousing and logistics supply chain management. The clothing industry is one of the most potential application areas of RFID. The changes brought about by RFID technology are not far away from us, and will be widely used in various fields. With the rapid development and integration of information technologies such as the Internet of Things, mobile Internet, and cloud computing, we may reimagine the construction of our business and IT systems in this era.
The main advantage of RFID warehouse management system over other types of identification systems (barcode identification) lies in its non-contact data collection and radio frequency tag read/write operations. High recognition rate, strong adaptability, resistance to light, temperature, humidity, dust, grease, and chemical reagents are also the reasons why RFID warehouse management systems are particularly suitable for use in special environments in various industries. Clothing warehouse management software combines RFID technology for data collection and daily business management, establishes a clothing information RFID management platform, supports important business processes of clothing warehouse management, and improves the efficiency of core business processes such as warehousing, outgoing, and inventory.

Six, the main functions of the software:
The RFID warehouse management system software platform mainly combines RFID technical characteristics with the warehouse management process, and realizes more scientific and visual management on the software. The following is an introduction to several important functions of the software:
1. Warehouse management
Deploy fixed RFID readers at the door of the warehouse, and carry out radio frequency planning according to the on-site environment. For example, four antennas can be installed up, down, left and right to ensure that RFID electronic tags are not missed. After receiving the warehousing order, put the product into the warehouse according to certain rules. When the RFID electronic tag (ultra high frequency) enters the electromagnetic wave range of the RFID fixed reader, it will be activated automatically, and then the RFID electronic label and RFID fixed reading The writer communicates. When the RFID tag is collected, it will be compared with the order to check whether the quantity and model of the goods are correct. If there are errors or omissions, they will be processed manually. Finally, the goods will be transported to the designated location and placed in accordance with the rules. The main advantage of RFID in warehouse management applications is non-contact long-distance identification, and can be read in batches, which improves efficiency and accuracy.
2. Outbound management
According to the pick-up plan, the goods out of the warehouse are sorted and processed and managed out of the warehouse. If the quantity out of the warehouse is large, push the goods to the door of the warehouse in batches, use a fixed reader to communicate with the tags, collect the RFID electronic tags of the goods out of the warehouse, and check whether they correspond to the plan. If there are errors, manually as soon as possible deal with. For a small amount of goods, RFID handheld terminals can be used to collect information from RFID electronic tags (handheld scanners or RFID tablet computers). When an error occurs, an alarm will be issued, and the staff should deal with it in time, and finally send the data to the management center Update the database to complete the delivery.
3. Inventory management
In accordance with the requirements of warehouse management, conduct regular and irregular inventory. Traditional inventory is time-consuming, labor-intensive, and error-prone. All these RFID solves these problems. When there is an inventory plan, the RFID handheld terminal is used to carry out inventory scanning, and the information of the inventory can be transmitted to the back-end database through the wireless network and carried out with the information in the database. Comparing, the generated difference information is displayed on the RFID handheld terminal in real time for verification by the inventory staff. After the inventory is completed, the inventory information is checked with the database information in the background, and the inventory is completed. In the inventory process, the system uses RFID non-contact reading (usually within 1 to 2 meters) to read clothing goods information very quickly and conveniently. Compared with the traditional model, it will improve a lot of efficiency and inventory accuracy. sex.
4. Basic information management
Set and manage the attributes of the goods, the main functions are, add, edit, delete, and query the basic attributes of the goods stored in the warehouse. In this way, it can be set according to the attributes of the operating products of different enterprises to ensure that it meets the individual needs of each enterprise. The warehouse can also be divided into locations, which can be divided into units such as warehouses, regions, and locations, so that large-scale warehouses can be managed more accurately. Warehouse managers at all levels can query and perform related business operations for inventory information of different dimensions.
5. System information management
Fully consider the scalability and security of the system, and provide reasonable tools to ensure system security. System management mainly completes the correction and maintenance of system operating parameters. Complete permissions assignment, add, modify, and delete data forms. At the same time, it has a complete login program (user name and password). Different personnel are given different permissions, which are set by the system administrator. The system also provides a one-key data backup and recovery function to further ensure the security and continuity of business data.
6. Data statistical analysis
The system can form statistical reports according to time, quantity and other elements, clarify the turnover period and efficiency, and facilitate the planning and control of the inventory management business process. The unified operation can speed up the speed of goods in and out of the warehouse, thereby increasing the throughput of the inventory center, and can provide Managers and decision makers provide timely and accurate inventory information, which can improve the accuracy of goods inquiries, reduce inventory levels, and improve the efficiency of the logistics system to strengthen the competitiveness of enterprises.
Seven, hardware system composition:
The hardware part of a complete RFID warehouse management system usually consists of: fixed RFID reader, fixed RFID antenna, handheld RFID reader, desktop RFID card issuer, and RFID electronic tags. Additional equipment: computer, PC server, switch, wireless router, network cable, data signal cable, etc. (equipment optional).Different hardware products with different characteristics can be selected under different application environments, RFID applications can be deployed very flexibly, and simple integration and rich application support are provided between each other to ensureRFIDMaximize business efficiency.
(1) Fixed RFID reader:
The fixed RFID reader integrates RFID reader module, TCP/IP communication module and reader power supply, providing simple integration and rich application support, and at the same time, it can read tags reliably and efficiently to realize remote Automatic data collection and wireless transmission in real time. Able to achieve seamless integration with the existing IT environment, filtering, mediation, user-defined correlation, selective monitoring and other functions help provide users with detailed real-time information, quickly collect and provide useful data.
(2) Fixed RFID antenna:
Due to the uncertainty of the direction of the electronic tag when the goods enter and exit the warehouse, in order to ensure the effective identification of multiple angles, a circularly polarized antenna is used. In order to ensure the accuracy and efficiency of the tags and not be misread or missed, the fixed RFID readers in many storage environments will be connected to four antennas to read and write tags from different directions. The type and gain of the antenna can be adjusted according to the requirements of the field application environment and reading and writing distance to ensure the realization of suitable reading and writing functions.
(3) Handheld RFID reader
Hand-held RFID readers are mostly used for warehouse inventory, and can also manage storage and storage operations, and support multiple communication transmission modes such as GPRS/WIFI. Utilizing the rugged waterproof and dustproof handheld RFID terminal with high industrial grade design, it has the ability to penetrate into the complex storage environment. Goods stored far away from the fixed reader (for example, on a storage rack) can still be processed using RFID tag information. Hand-held RFID mobile terminals can provide greater flexibility and can read remote areas that cannot be reached by a fixed reader, so that RFID-labeled goods can be tracked comprehensively.
(4) Desktop RFID card issuer
RFID desktop card issuer is a desktop reader, suitable for reading and writing a series of electronic tags working in the UHF frequency band. Built-in small antenna, as a card issuing device, the typical distance for reading electronic tags is 10cm. Multi-tag identification and anti-collision mechanism, following the ISO18000-6C protocol; it can read the ID number or EPC code in multiple electronic tags at the same time; read and write data in the user data area of the electronic tag, and provide a USB interface for data communication and card issuance The device is powered, and a password can be set to lock the data area to prevent the data in the electronic tag from being rewritten.
(5) RFID electronic tags
Due to different industry application environments, there are many types and specifications of goods. Attach labels or tag labels suitable for different sizes and specifications are required to meet the communication needs of different application environments. Warehouse management generally uses ultra-high frequency (UHF) electronic tags, high-performance chips, in line with relevant standards, and the working frequency is 902-928. RFID electronic tags used in normal environments have excellent performance, strong reliability, small appearance and easy to use. The tag contains an anti-collision mechanism, which can be applied to the application of multi-tag identification. The data can be read without a light source and can even be carried out through the outer packaging.
8. Hardware deployment plan
The scientific deployment of RFID hardware is essential to a successful RFID practice. The accuracy of RFID communication depends on a good radio frequency environment. It is necessary to focus on the specific environment of the enterprise, such as the reasonableness of the overall application environment, the deployment position of the reader, the placement of the antenna and the choice of the gain size, the RFID electronic tag sticking scheme on the goods, etc., these are all Need to consider. Let me share with you some conventional deployment schemes:
1. RFID label placement scheme
RFID electronic tags are the only signs that identify the goods in the warehouse, so pay special attention to them when placing them. Because the label placement is directly related to the installation method of the reader antenna and the reading and writing effect of the label. In order to obtain the best read and write effect, the polarization direction of the reader must be consistent with the polarization direction of the tag.
Here, the labels are mainly divided into anti-metal labels and non-metal labels to identify goods with different media. Anti-metal labels are affixed to the surface of metal goods. Non-metallic labels (including cards, stickers, Inlay, etc.) are mainly affixed to non-metal goods labels, such as wooden boxes, canvas bags, plastic bags, cartons and other goods. It can be identified by a non-metallic label. Labels can be affixed to the packaging box. When placing the labels, they should be placed outwards. They need to have a certain degree of regularity and should not be pasted indiscriminately.
2. Fixed reader/writer deployment plan
According to mobility, readers can be divided into fixed and mobile readers. According to the degree of integration of the antenna and the processor module, fixed readers can be divided into integrated readers and split readers.
The integrated reader is integrated with the antenna and the processor module, while the split reader generally can be configured with multiple antennas, and the four-port reader can be configured with 4 split antennas.
The size of the antenna can be selected, and the radio frequency signal between the antenna and the feeder is transmitted through the feeder. When multiple antennas work, the antennas work in turn to poll work to read the electronic tags in the field.
Take the standard warehouse door (door height 3.0m, width 4.0m) and standard (length*width*height 120cm*100cm*15cm) pallets as an example. The split reader has multiple antenna interfaces. The size of the antenna can be appropriately selected according to needs. Generally, a 10dBi circularly polarized antenna is selected as the reader adapter antenna of the warehouse management system. The radio frequency signal is transmitted through the feeder.
The quality of the feeder also directly affects the signal transmission quality. Generally, the attenuation factor of a good antenna is: less than 1.5dB/10m. In the warehouse management system, the length of the feeder generally does not exceed 10m, that is, the length of the trace between the reader and the antenna does not exceed 10m. The figure below shows the installation method of the split reader at the entrance and exit of the warehouse.
Installation on both sides of the doorway
Split readers are installed on the top in different areas of the warehouse
