Clothing is a kind of personalized product with different styles, sizes and colors. In order to occupy the market in time, guide the fashion trend, and grab the products that the market needs, the company captures the ever-changing market information in time and performs various information Analysis, the most useful data comes from the front line of sales, including the inventory of each point of sale, customer shopping records analysis. At present, China’s apparel companies are developing towards the goals of industrialization, scale, branding and grouping. In order to achieve this goal, many companies have invested in information management systems or ERP systems, but the potential of most corporate management systems has not been fully utilized. The main reason lies in the lack of practical operation and maintenance experience and capabilities in the application of information technology. At the same time, the inability of data collection methods to meet the needs of the information management system is also a major obstacle. As the carrier of data, bar code provides a new data collection technology. It has high accuracy, fast input speed, low investment, flexible and practical, and promotes the unimpeded flow of information. At the same time, it provides timely and accurate data for the enterprise management information system. The management system exerts the highest efficiency and makes decisions that can truly support the enterprise on this basis. The application of barcode-based data acquisition technology runs through the entire process of enterprise management, and the most typical and effective applications are embodied in warehouse management, production management and sales management.
1. Data collection technology
Data collection technology can be divided into: wired technology, offline technology (batch processing technology), wireless technology.
1. Wired technology
The application of wired technology can be seen everywhere, from the convenience store cash register to the assembly line of the logistics distribution center. The realization of wired technology is completed by barcode scanner, data terminal and local area network. This kind of technology is characterized by small investment and fast implementation, but it has many limitations, mainly limited to the operating area of the scanner. It is precisely because of this limitation that wired technology is suitable for use in fixed-station production sites. Wired technology system diagram (Figure 1):

2. Offline technology
Off-line technology is widely used in warehouse management. This technology is also called batch processing technology. The implementation of off-line technology is completed by the data collection terminal (HandyTerminaJ), PC and local area network.

In the process of warehouse management, the objects of management generally include raw materials and finished products; the process of management includes warehousing, outgoing, shifting, and inventory. The most important data in the warehouse is the inventory quantity. We hope to know the quantity of raw materials and finished products in real time. To do this, you must first number these items, mark the printed barcode labels on the items through a barcode printer, and provide an identification that can be used to identify the item. It is also a unique identification for this item. It cooperates with other technologies. To achieve the purpose of data collection.
3. Wireless technology
The realization of wireless technology is completed by wireless data collection terminal (RF), wireless access point (AP), and middleware. It is suitable for applications where there is a large on-site operating environment, there is no condition to set up a wire network, high requirements for real-time data, and high requirements for information interaction. August 23, 2002; China Radio Regulatory Commission increased the power of 2.4GHz wireless transmission, so that the IEEE802.11b2.4G wireless transmission protocol can be used smoothly in the country, opening up a broad prospect for the application of wireless technology, although bar code technology The combination with wireless technology is only a small part of it, but it can maximize the advantages of data collection automation and stimulate the potential of enterprise management.
In the production workshop, employees may need to move around at any time. In large warehouses, dozens of operators need to accept various work instructions, feed back the work situation, and frequently enter and exit the warehouse. At this time, the wired network seems to be a chain, which limits the management information system. Application, the best solution to these problems is wireless technology. Barcode-based wireless technology can not only complete all the work of wired technology and batch processing technology, it also realizes real-time data transmission and information interaction.

Take warehouse management as an example. Every operator with a wireless data collection terminal can see the work instructions issued to him on the screen. The instructions include the product name, product serial number, quantity, and location number that need to be shipped out of the warehouse. And some auxiliary information of products, the operator scans the products that need to be shipped out or put in the warehouse according to the screen prompts, and provides them to the system for verification. After completion, the confirmation information is fed back to the system, and then the system assigns another task. Such a workflow greatly reduces the uncertainty and waste of human resources transmitted through paper documents, and avoids information jams caused by the inability of timely feedback of information. There is another advantage of using wireless technology for warehouse management. It can realize the simultaneous operation of inbound and outbound operations and inventory operations. Because the data obtained is real-time, the inventory can be checked in time before or after the inbound and outbound, and timely feedback when problems are found can be avoided. Abnormal moral loss. When managing the location, the operator can be prompted to move the location, merge the location, split the location, etc. This is undoubtedly a great help for an inexperienced operator. Wireless technology has left ample room for imagination for the reorganization of business processes.
No matter which technology is used, the ultimate goal is to help companies improve their profit margins and core competitiveness. Through the rapid and accurate sales data provided by automatic identification technology, analysis and mining are carried out to improve the response speed of consumers’ new demand (ie market demand), so as to quickly transfer to the profitable part of the market, and Join in the role that influences consumer demand. At the same time, it also improves the flexibility of the enterprise to deal with complex products, complex processes, changing raw materials and multiplying product series.
2. Examples of the application of data collection technology in the clothing industry
Shanghai Zhonghuai Garment Co., Ltd. keeps abreast of product inventory in time through inventory of various stores, specialty stores and factory warehouses, and generates sales reports through inventory statistics at various sales points every day.
Shown is the daily sales statistics of the company’s products in Weifang, Shandong
All processes can be completed quickly and accurately every day through the use of bar code identification and data collection of bar code identification, and the necessary sales data can be counted to guide the company’s production, distribution, sales and even capital withdrawal. As a result, Zhonghuai Garment Co., Ltd. solves the problems of untimely market information feedback; obstacles and disconnects in the supply chain within and between enterprises; product backlogs and poor capital turnover, which have long hindered the development of the enterprise. Does a small bar code really have such a great effect? The following is a detailed analysis of the bar code-based automatic identification technology and the actual application of clothing companies.
Third, the application of barcode in the production process
Workers work at fixed stations, and the barcode can be marked on the processing sheet or on the garment being processed. The barcode on the processing order can control the product to batch size, and the barcode on the garment can control each product. For large-volume, low-value products, you can use batch management; and expensive clothing, especially many handmade clothing, must be managed to the smallest unit, that is, each product.
The platform scanner and handheld scanner are fixedly installed on the workbench to identify the barcode on the processing sheet or clothing, and record the processing process of the clothing. After the barcode scanner reads the barcode, it transmits the data to the wired data terminal, which is installed under the workbench. The terminal temporarily stores or instantly transmits the data recognized by the scanner according to actual needs. For the barcode of a single product, the terminal can instantly transmit the data to the production management system, because the processing time of a single product is relatively short. The barcode of the batch product needs to be confirmed when it is completed, and the system will record the starting time of the batch product processing and other information.
The actual configuration needs: a scanner corresponds to a data terminal, each data terminal is connected to each other through the RS485 network, and each barcode scanner is relatively independent and not related.
At the production site of apparel companies, bar code collection based on wired technology can help companies achieve product quality traceability and employee performance appraisal. Apparel companies are labor-intensive companies with many processes and complicated operations. A slight negligence can easily cause quality problems. In some key positions, once a problem occurs, the entire batch of products will be affected, and the product level may be lowered or even scrapped. . Through barcode management, barcode scanners are used in key positions to record product processing conditions, record employee work conditions, and transmit data to the management system in real time through terminal and local area network wiring, so that you can grasp the production status of products in time. You can also observe the working conditions of the workers. It is also very convenient for quality tracing after a problem occurs. As long as the product’s serial number is retrieved in the information management system, it is easy to find the processing technology and the actual operator of the product. At the same time, it can meet the requirements of IS09001:2000 for product quality traceability, and improve the level of corporate management and international standards. In piece-rate jobs, the use of a platform-style barcode scanner can quickly record the employee’s daily workload. Through the recording of working hours, it is also possible to grasp which period of time the employee works most efficiently, so as to facilitate the company to arrange employees reasonably Rest. Some clothing companies take a 10-minute break every hour of work, which is obviously a bit too average, and there is no reasonable analysis of the work efficiency of the employees.
Fourth, the application of offline technology in warehouse management
Jiangsu Jiangyin Sunshine Group has introduced the world’s most advanced spinning, weaving, dyeing, testing and clothing complete equipment from dozens of countries including Germany, France, Italy, Switzerland, and Belgium. It currently has 115,000 worsted spinning spindles. There are 600 looms, 2 high-end clothing production lines; 20 categories with more than 6000 varieties, forming an annual output of 22 million meters of Sunshine brand high-end worsted wool and cashmere, and 60.5′ sets of high-end clothing. In the large and small warehouses of the group, offline technology is used to realize the warehouse in and out management. Inbound and outbound process:
Each piece of fabric and wool that needs to be in and out of the warehouse is marked with a barcode. The data collection terminal collects the barcode on the warehousing cloth in batches. The collected data is temporarily stored in the terminal, and the piece number, article number, and color of the cloth are recorded during collection. Number, quantity, date, operator number, and finally upload the data in batches to the PC and import it into the management system. When leaving the warehouse, the management system will export the information of the cloth that needs to be out of the warehouse. The same exported information includes the piece number, article number, color number, and quantity of the cloth. This information is downloaded to the data collection terminal before the warehouse is released, and then the information needs to be released from the warehouse. The cloth is scanned. Each time it is scanned, the screen of the data collection terminal will display the characteristic information and the quantity of the cloth for inspection and verification by the operator to avoid errors. If the scanned cloth is not within the scope of the cloth out of the warehouse, the data collection terminal will give a warning. You can refuse to leave the warehouse or force it out of the warehouse, but every step of the operation will be recorded by the terminal. When leaving the warehouse, it will also record the area or customer where the cloth is exported, as well as the time and operator of the warehouse. Finally, these outbound information will also be fed back to the management system to form detailed and accurate inbound and outbound records in the system.
Offline technology greatly reduces the work of on-site staff to check and verify, avoid manual recording and input errors, and improve efficiency. At the same time, it also provides a verification function, which greatly improves accuracy. Sunshine Group eliminated information errors due to input errors and reduced the delivery error rate to 2% after using it. However, the timely rate of information feedback has increased significantly. Such advantages are also concentrated in the inventory process of warehouses, chain stores, specialty stores, franchise stores, and specialty counters.
A large part of domestic clothing companies do export clothing processing. In addition to the product barcodes marked on each product, foreign companies generally require the use of UCC/EAN-128 codes on the outer packaging of their products.
Before the product is shipped, the domestic enterprise transmits the shipping information to the counterparty company through the EDI (Electronic Data Interchange) system, and the counterparty company checks and accepts the goods through the identification of the barcode label when receiving the goods. It can be seen that the integration of physical objects and barcodes realizes the parallelism of logistics and data flow. All the bar code technologies mentioned above can be used in combination with UCC/EAN-128 code to achieve the purpose of management. At present, many enterprises such as Shanghai Zhengzhang Textile Factory and Shanghai Jiali Velvet Embroidery Factory have realized the barcode of export products.
