UHF RFID Laundry System

I. System Overview
At present, hotels, hospitals, bathhouses and professional laundry companies are facing the process of handing over, washing, ironing, finishing and storing thousands of pieces of work clothes and cloths every year, so it is a great challenge to effectively track and manage the washing process, number of times, inventory status and effective categorization of each piece of cloth.

1. paper-based handover of laundry tasks, complicated procedures and difficulty in making enquiries.
2. The fear of cross-infection makes it impossible to count the number of certain cloths to be washed, and the mismatch between the number of good laundered items and those collected is prone to commercial disputes.
3、Each step of the laundry process cannot be accurately monitored, and there are missed treatment links for the cloths.
4、The problem of accurate categorisation of the laundered cloths

This system uses RFID technology to apply UHF (Ultra High Frequency), UHF laundry tags to the intelligent management of laundry, building an efficient working platform for rapid collection, sorting, automatic inventory and picking up of laundry in the laundry industry, greatly improving efficiency and reducing error rates. This system has the following features when compared with traditional manual management.

1. Batch scanning for identification without individual scanning, facilitating manual handover and management work and making it easy and quick to use.
2、Improve work efficiency and economic efficiency, saving personnel expenses and reducing costs.
3, fully automatic design, improve service quality.
4、Can accurately distinguish between customers, laundry categories and their due preferential services.
5、Record customer information and laundry statistics, generate all kinds of reports, can 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 the system is to use the uniqueness of the UHF RFID tag and the read-write to scan the characteristics of the long-distance fast one-time batch, the specific characteristics of its hardware equipment are as follows.

1, the uniqueness of the label, anti-counterfeiting each chip has its own "identity card": the world's only digital code, and this digital code in the factory production has been cured in the chip, can not be changed, and there is a storage area, you can store the label belongs to the category, customers and other information.
2, read-write high recognition rate, high stability; reliable recognition distance of not less than 6m; reliable recognition of up to 80km/h fast moving target; recognition rate of up to 200 tags per second;
3、Ability to achieve multiple tags in the read-write area at the same time to read, with anti-collision function.
4, high information security and confidentiality performance.

This intelligent laundry application system has the following advantages compared with the traditional manual management.
1) Reduced manual management work, easy and fast to use.
2) Improved efficiency and economic benefits, saving personnel expenses and reducing costs.
3) fully automatic design and improved service quality.
4) the ability to accurately differentiate between customer categories and preferential services available
5) a sensitive and reliable system, with safe and durable equipment
6) Record and keep customer information and laundry records, and can query and print information at any time.

II. System design
Each hotel, including the restaurant and several banqueting areas, has to use textile table linen, and several hundred rooms need to supply bathrobes, bed linen and towels, which is quite a lot. 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 how many 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.

The system, as shown in the diagram, begins with the installation of RFID antennas and readers in each customer hotel, on the doorway where laundry enters and exits, with the readers transmitting 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 tags 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 clothe laundry chip 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.
