Application Research of RFID Technology in Fine Management of Laundry

At present, RFID technology has penetrated into all aspects of people's lives, and more and more applications have achieved more convenient management through RFID technology. There is no uniform cleaning standard for clothes due to different differences in materials and styles, which results in the laundry process often being complicated every time the laundry is classified, resulting in inefficient work.

研究表明,肮脏的织物整理process can produce fly ash or aerosol that can carry infectious pathogens, which not only pollutes the air environment in the affected area, but also increases the occupational exposure and cross-infection risk of fabric collectors. The health industry standard of the People's Republic of China "Technical Specifications for Washing and Disinfection of Hospital Medical Fabrics (WS / T 508-2016)" stipulates that dirty fabrics and infectious fabrics should be collected separately, and jitter should be reduced when collecting.

For medical institutions, on the one hand, the general disinfection of ordinary dirty fabrics includes chemical disinfection and wet heat disinfection in the washing process, and dry heat disinfection in the drying process. Several rounds of chemical and physical disinfection are down to ensure the cleanliness of the fabric. degree. For heavily contaminated fabrics, even infectious fabrics, the sterilization method is more strict, no matter from the amount of disinfectant, or the temperature of washing and drying, strict control has been made to ensure the quality of disinfection. On the other hand, the medical textiles of large medical washing enterprises from the sorting, washing, disinfection to drying, folding, and packaging have achieved the maximum mechanical automation operation so far, to avoid cross-infection caused by dirty fabrics to people, and also avoid People cause secondary pollution to clean fabrics.

In the process of manual collection and sorting of medical dirty fabrics, fly dust or aerosols with potentially infectious bacteria will be disseminated, which not only causes air to the environment of hospital public places (including outpatient and emergency departments, wards of various departments, etc.) Contamination will also increase the risk of occupational exposure and cross-infection of fabric collectors. Using RFID technology, non-contact collection of dirty fabrics can be achieved and scanned. In less than one second, you can know which department, which ward, and which category the medical fabric comes from. Then, the background will automatically print out a list , Effectively prevent infections that may be caused by manual inventory and shaking of dirty fabrics.

For the management of laundry in daily dry cleaners, the intelligent central laundry factory plays a key role. It realizes laundry automation, digitization, standardization, and visualization. Each piece of clothing has its own unique 'identity card'-RFID electronic tag.

第一个of all, RFID tags will be accompanied by clothing all the way from collection to delivery. A cleaning process will go through admission points, entrance inspection, classification before washing, stain removal before washing, classification washing, classification drying, quality inspection before ironing, sterilization and shaping, classification ironing, quality inspection, accessory matching, sterilization and disinfection , Finished product packaging, factory distribution, factory review a total of 16 procedures. And after each process, the clothing information will be recorded into the chip once. The chip can ensure that every step of washing clothes is recorded, and customers can query the washing status of clothes at any time. In some important operations, customers can also visualize the laundry process by watching videos on the relevant apps, specifically knowing which technician and which machine cleans the clothes.

Based on RFID technology, automatic data collection is carried out on the data of various operational links such as linen washing, handover, storage, automatic sorting, inventory counting, etc., and will be collected by Honglu UHF handheld terminal and Honglu fixed reader The data is uploaded to the background system in real time, and the status of each link of linen circulation is grasped in real time, and the number of washing times, washing costs, and the number of rentals and rental fees are counted in real time. Visualize the whole process of washing management and provide real-time data support for the scientific management of the enterprise.

RFID laundry washing management system can automatically count the number of fabrics put into various departments in various turnover states, and use a portable RFID reader to the work area for non-contact scanning inventory, quickly and easily read the data information of the laundry, and realize You can accurately count the type and quantity of clothing without opening the cabinet. Checking the inventory results and the release records, you can find changes in asset shortages and surpluses, find and analyze the causes of differences, and strengthen the system construction and link management to solve problems in clothing management.
