γ1. System overview
At present, hotels, hospitals, baths and professional washing companies are dealing with thousands of work clothes and linen handover, washing, ironing, finishing, storage and other processes every year. How to effectively track and manage each piece The cleaning process, frequency, inventory status and effective classification of 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, the statistics of some linens to be washed cannot be carried out, and the mismatch between the washed quantity and the time of collection is likely to cause commercial disputes;
3. Each step of the washing process cannot be accurately monitored, and the linen has a missing processing link;
4. The problem of accurate classification of washed linen
This system uses RFID radio frequency identification technology, applies UHF laundry tags to the intelligent management of laundry, and builds an efficient work platform for fast collection, sorting, automatic inventory, and collection of laundry in the laundry industry. Greatly improve work efficiency and reduce error rate. Compared with traditional manual management, this system has the following characteristics:
1. Batch scanning and identification, no single scanning, convenient for manual transfer and management work, convenient and quick to use;
2. Improve work efficiency and economic benefits, save personnel expenses and reduce costs;
3. Fully automatic design to improve service quality;
4. Can accurately distinguish customers, laundry categories and their due preferential services;
5. Record customer information and laundry statistics, generate various reports, and query and print information at any time.
6. The system is sensitive and reliable, and the equipment is safe and durable;
The core idea of ββthe system is to use the uniqueness of UHF RFID tags and the reader’s ability to quickly scan batches at a long distance. The specific characteristics of the hardware equipment are as follows:
1. Label uniqueness and anti-counterfeiting. Each chip has its own “ID card”: the only digital code in the world, and this digital code has been solidified in the chip during production in the factory and cannot be changed, and there is a storage area , Can store information such as the category and customer of the label.
2. The reader has a high reading rate and high stability;
The reliable recognition distance is not less than 6m;
Reliably identify fast moving targets up to 80km/h;
The recognition rate is up to 200 tags per second;
3. It can realize the simultaneous reading of multiple tags in the reading and writing area, and has the function of anti-collision;
4. High information security and confidentiality performance.
γ2. System design
Each hotel includes hundreds of guest room covers, bed sheets, bath towels and towels, etc. The quantity is quite large. So many textiles have to leave the hotel every day and return to the hotel after washing, pressing and folding. In addition to so many hotels, It is more difficult for washing shops to track the location and quantity of those textiles, and to confirm whether they have all been returned.
For hotels: I hope to be able to track the number of times each item has been cleaned, estimate the service life of these items based on the number of cleanings, and also hope to receive an alert when the item reaches the maximum number of cleanings, indicating that the item may be needed replace.
For washing shops: it is necessary to distinguish different types of textiles in different hotels and the number of times each textile is cleaned. At the same time, it is also necessary to solve the problem of quickly checking the washing products and the inventory and outgoing lists when the hotel is handed over. The use of RFID UHF laundry tags just solves the above needs.
