1. Application Introduction
At present, hotels, hospitals, baths and professional washing companies are facing the handling of thousands of pieces of work clothes and linen handover, washing, ironing, finishing, storage and other processes every year. How to effectively track and manage each piece The washing process, washing times, inventory status and effective classification of the linen are a great challenge. The traditional washing industry mainly faces the following problems:
1. Handover of paper washing tasks, complicated procedures, and difficult inquiries;
2. Due to the fear of cross-infection, some statistics on the quantity of linen to be washed cannot be carried out. The mismatch between the quantity of washed and collected is prone to commercial disputes;
3. Each step of the washing process cannot be accurately monitored, and the linen has been missed;
4. The problem of accurately classifying the washed linen.
The introduction of UHF RFID radio frequency identification technology will make the user’s laundry management intelligent. The FU-M6-A of Quanshunhong Company is a four-channel UHF RFID reader with excellent performance. It has a high-speed reading capability of 750 tags/sec. At the same time, the industry-leading anti-collision algorithm can ensure reading and writing. The device realizes the key feature of no missed reading when processing tags at high speed, and can connect up to 4 antennas to work at the same time, with a wider coverage, which is convenient for the rapid statistics and handover of large-scale linen to be washed. The FU-M6-A four-channel reader also has ultra-high receiving sensitivity, which is particularly important for the reading of some wet linen tags during the handover process. The higher receiving sensitivity can better adapt to the harsh reading environment.
The good reading performance of the FU-M6-A four-channel reader of Quanshunhong Company can help users realize the transparency, intelligence and high efficiency of laundry management, and solve the management problems that cannot be achieved by other technologies in the past.
A button-shaped (or label-shaped) electronic tag is sewn on each piece of linen. The electronic tag has a globally unique identification code, that is, each piece of linen will have a unique management identification until the linen is scrapped (label Can be reused, but does not exceed the service life of the label itself). In the entire linen use and washing management, the use status and washing times of the linen are automatically recorded through the RFID reader. Supports batch reading of labels during washing handover, making the handover of washing tasks simple and transparent, and reducing business disputes. At the same time, by tracking the number of washes, it can estimate the service life of the current linen for users and provide forecast data for the purchase plan.
2. System design
1. Label sewing
The button label can be sewn through a small cloth bag or directly on the linen to be managed. The sewing position is easy to find. It is recommended to choose a fixed position.
2 Data entry
The chip in the RFID tag can store data, associate the attributes of each piece of laundry to be managed with the RFID tag ID to the database, and record and track the workflow and life cycle of each piece of linen.
3. Linen handover
Install a fixed reader channel in the hotel, the reader is connected to the washing center system, after the linen is packaged, the fixed reader can directly load the linen information in batches, and generate the handover list in real time.
4. Other
The software side of the system can realize the tracking of the washing status, the statistics and early warning of the washing times of the linen, the scrapping of the linen, the inventory management and other functions.
