At present, hotels, Hospitals, bathhouses and professional washing companies are facing thousands of work clothes and linen handover, washing, ironing, sorting, storage and other processes every year. How to effectively track and manage each piece The washing process, washing frequency, inventory status and effective classification of linen are a great challenge:

1. Handover of washing tasks on paper is complicated and difficult to inquire about;

2. Due to the fear of cross-infection, some statistics on the number of linen to be washed cannot be carried out, and the mismatch between the number of washed and the task is likely to cause commercial disputes;

3. Every step of the washing process cannot be accurately monitored, and there is a missing treatment link for the linen;

4. Accurately classify the washed linen to save storage space;

5. Unable to accurately arrange the minimum safety stock for each piece of linen.

The introduction of RFID radio frequency identification technology will make the user's laundry management more transparent, improve work efficiency, and solve management problems that could not be achieved by other technologies in the past, such as: large-scale statistics of linen to be washed, handover.

The solution is to sew a strip-shaped rfid electronic tag on each piece of linen. The rfid electronic tag has a globally unique identification code, that is, each piece of linen will have a unique management mark until the linen is scrapped ( RFID tags can be reused, but not beyond the life of the tag itself). In the entire linen use and washing management, the use status and washing times of the linen will be automatically recorded through the RFID Reader. It supports batch reading of tags during washing handover, making washing task handover simple and transparent, and reducing business disputes. At the same time, by tracking the number of washings, it can estimate the service life of the current linen for the user and provide forecast data for the procurement plan.

System function

1. Labor can be reduced by 40-50%;

2. More than 99% of linen products can be visualized to reduce the risk of missing linen;

3. The improved supply chain management will reduce the service time by 20-25%;

4. Improve the accuracy and reliability of Stored information;

5. Efficient and accurate data collection, providing operational efficiency;

6. Automatic collection of distribution, recovery and handover data to reduce human errors;

7. Reduce the overall cost of linen washing management for users.

The main components of the system

1. RFID tag

2. RFID tag issuer

3. RFID fixed reader

4. RFID handheld reader

5. Intelligent laundry management system

System design scheme:

1. Label sewing

The strip-shaped label is used, which can be sewn on the linen to be managed through a small cloth bag or directly. The sewing position is selected to be easy to find. It is recommended to choose a fixed position uniformly.

2. Customer management

Add and modify customer information, including unit list, contact person, phone number and address, etc.

3. Label entry

The chip in the RFID tag can store data, associate the information of each piece of laundry to be managed with the RFID tag ID into the database, and record and track the workflow and life cycle of each piece of work clothes and linen.

4. Check the dirt

The dirt sewn with RFID tags is packed directly. The quantity is automatically collected through the fixed RFID reader channel, and the ID of each piece of dirt read is recorded. Since the data is not manually counted, on the one hand, it improves work efficiency, and it also brings convenience to the hospital, providing high-quality services.

5. Inventory of clean linen

After the linen is cleaned, it passes through the fixed RFID reader channel again to check and check whether there is any linen missing during the washing process, and print out the record for handover to the user.

6. Linen sorting and classification

With the help of the uniqueness of RFID tags, it can help sort the linen in each ward, and use the RFID reading device to confirm whether there is any misplacement before packing.

7. Linen inquiry

By scanning the label of the linen, you can query the information of each piece of linen to prevent loss and confusion.

8. Inventory inquiry

The process of system assembly

1. Product identification:

Identify each piece of clothing by sewing a button-mounted RFID electronic tag on each piece of laundry that needs to be managed. There is a globally unique ID number in the RFID tag chip, and there is a user area for writing data. The specific attributes of the clothing can be written in the tag, such as the owner of the clothing, the life of the clothing, the number of washing times of the clothing, the model of the clothing, etc. .

2. Automatic counting:

It is divided into inventory of incoming objects and inventory of outgoing objects, and the quantity is accurate each time. For packaged dirt, the entire package can pass through the RFID tunnel reading device for accurate inventory, and the accuracy rate can reach 100%. The data is objective and scientific, and can be used with The user checks the handover quantity. At the same time, the clean clothes to be returned to the user are also confirmed and listed through the RFID tunnel reading device.

3. Automatic sorting:

At present, enterprises and users hand over clothes manually. Therefore, the uniqueness of RFID tags can be used to sort clean clothes in the washing factory area, and directly sort them to the smallest user unit and pack them into lists, which saves manual sorting time. Reduce personnel labor.

4. Record of washing times:

Due to the characteristics of RFID tags, it is possible to record the washing times of clothes, predict the life of clothes, reasonably control clothes inventory, and provide users with more scientific services.
