1、System overview This system applies RFID technology to the identification and management of individual clothes. Based on RFID laundry tag for clothes, it is a highly efficient platform for the laundry industry to quickly collect, sort, automatically inventory and pick up clothes, greatly improving efficiency and reducing error rates.
This intelligent laundry application system has the following advantages compared to traditional manual management. 1) Reduces manual management work, easy to use and fast; 2) Improved efficiency and economic benefits, saving staff costs and reducing costs; 3) Fully automatic design to improve service quality; 4) Accurate differentiation of customer categories and preferential services; 5) The system is sensitive and reliable, and the equipment is safe and durable; 6) Record and save customer information and laundry records, can be checked and printed at any time.
2. System design Each hotel, including the restaurant and several banqueting areas, uses textile table linen, and hundreds of rooms need to be supplied with bathrobes, bed linen and towels - a considerable amount. With so many textiles leaving the hotel each day, waiting to be washed, pressed and folded before being returned to the hotel, having so many makes it more difficult for the laundry to track where those textiles are, how many there are, and to confirm that they have all been returned.
Some hotels want to be able to track the number of times each item has been washed and estimate the life expectancy of those items based on the number of washes. Hotels also want to be able to receive alerts when an item has reached its maximum number of washes, indicating that the item may need to be replaced. The application of our RFID in the laundry industry addresses exactly these needs.
Firstly, in each customer hotel, RFID antennas and RFID readers are installed in the doorways where laundry enters and leaves, and the readers transmit the data to a client server within the hotel. In each laundry in and out of the doorway also the same installation RFID antenna and read-write, and client server. The client server in the hotel and the client server in the laundry are connected to the data centre server. RFID laundry chip are first installed on each item of laundry and staff write customer information and laundry information onto the tags, which are stored in a separate web-based software system.
When the items need to leave the hotel to be sent to the laundry for cleaning, they are stacked on a trolley and have to pass through a doorway where an RFID reader with four antennas is installed. The reader will obtain the ID number of each item at any point when the item passes through the doorway and transmits these ID numbers to the back-end system within the hotel via a cable connection, which then stores data indicating that the item has been sent to the laundry and creates an item delivery list.
Each hotel's sends the laundry to the washing shop when also passes through a doorway equipped with RFID antenna and read-write, the read-write will read the ID information of the item transmits to the server of the washing shop, stores the data, also illustrates, which hotel has how many clothes to this washing shop to wash, and can check the textile in out of the hotel when the quantity and the quantity into the washing shop.
After classification into the laundry process, washing is completed, through the sorting after the clothing is sorted packet, through the read-write again reads all the clothing laundry tags rfid information in the packet, and with the corresponding sends the laundry task order to check the data, confirms after sends to each hotel.
When the laundry sends the items back, it still has to go through the respective portal. The software compares the ID numbers of the returned item tags with the ID numbers of the items sent for cleaning to determine if they have been returned, if the quantities are correct and to store the information again. In hotels and laundries operational reports can be run which record, for example, how often items were cleaned, when they were cleaned and which ones were not returned.
