First, the background
At present, hotels, hospitals, baths and professional washing companies are facing the process of handling thousands of pieces of work clothes, linens, washing, ironing, finishing and storage every year. How to effectively manage each piece? The washing process, the number of washings, the inventory status and the effective classification of the linen are a great challenge:
1. The paper washing task is handed over, the procedure is complicated, and the query is difficult;
2, because of the fear of cross-infection, the statistics on the number of certain cloths to be washed can not be carried out, the number of washings and tasks do not match easily lead to commercial disputes;
3. Each step of the washing process cannot be accurately monitored, and the linen is leaky;
4. The washed linen is accurately classified to save storage space;
5. The minimum safe stock of each piece of linen cannot be accurately arranged.
Second, the system introduction
The introduction of RFID radio frequency identification technology will make the user's laundry management more transparent, improve the work efficiency, and solve the management problems that cannot be realized by other technologies in the past, such as: large-scale statistics of the cloth to be washed, Handover.
The solution is to sew a strip-shaped electronic label on each piece of cloth. The electronic label has a global unique identification code, that is, each piece of cloth will have a unique management mark until the cloth is scrapped (label can be Reuse, but not exceed the life of the label itself). In the entire cloth use and washing management, the use state and the number of washings of the cloth will be automatically recorded by the RFID reader. Supports batch reading of labels during washing and handover, making the task of washing tasks simple and transparent, reducing business disputes. At the same time, by tracking the number of washings, the user can estimate the current life of the linen and provide forecast data for the procurement plan.
Third, the system efficacy
1, labor can be reduced by 40-50%;
2. Visualize more than 99% of the linen products to reduce the risk of missing cloth;
3. Improved supply chain management will reduce work time by 20-25%;
4. Improve the accuracy and reliability of stored information;
5. Efficient and accurate data collection to provide operational efficiency;
6. Distribute and recycle the automatic collection of handover data to reduce human error;
7. Reduce the overall cost of user's linen washing management.
Fourth, the main components of the system
1, RFID electronic tags
2, RFID tag card issuer JY-U8632
3, RFID fixed reader JY-U8910
4, RFID handheld reader JY-U7900
5, Guangzhou Jianyong Laundry Management System
Fifth, system design
1, label sewing
The strip shape label can be directly sewed on the cloth to be managed through a small cloth bag, and the sewing position is easy to find. It is recommended to select a fixed position uniformly.
2, customer management
Add and modify customer information, including list of units, contacts, phone and address.
3, label entry
The chip in the RFID tag can store data, associate each piece of information to be managed with the RFID tag ID into a database, and record and track the workflow and life cycle of each piece of work clothes and linen.
4, dirt check check
The dirt with the RFID tag is directly packed. The number is automatically collected by a fixed RFID reader channel and the ID of each piece of dirt read is recorded. Because the data is not manually counted, on the one hand, it improves the work efficiency, and brings convenience to the hospital side and provides high-quality services.
5, clean linen inventory
After the linen is cleaned, check again through the fixed RFID reader channel to check whether there is a lack of linen during the washing process, and print the records to be handed over to the user.
6, linen sorting classification
With the uniqueness of the RFID tag, it can help sort the linen of each ward, and confirm the misplaced position through the RFID reading device before packaging.
7, linen query
You can check the information of each piece of cloth by scanning the label of the linen to prevent the loss and confusion.
8, inventory inquiry
Sixth, system assembly process
1. Product identification:
Each piece of clothing is identified by sewing a buttoned RFID electronic tag on each piece of laundry that needs to be managed. The RFID smart tag chip has a global unique ID number, and has a user area for writing data, and can write specific attributes of the clothes in the tag, such as the owner of the clothes, the life of the clothes, the number of washings of the clothes, the model of the clothes, etc. Wait.
2, automatic counting:
It is divided into incoming material inventory and physical inventory, accurate number of handovers each time. For packing dirt, it can be packaged through RFID tunnel reading equipment for accurate inventory, and the accuracy rate can reach 100%. The data is objective and scientific and can be used to The user checks the number of handovers. At the same time, the clean clothing that is ready to be returned to the user is also confirmed by the RFID tunnel reading device and lists.
3. Automatic sorting:
At present, enterprises and users manually transfer clothes. Therefore, the uniqueness of RFID tags can be used to sort clean clothes in the washing plant area, and directly sort to the smallest user unit and package the list, which can save manual sorting time. Reduce staffing.
4, washing times record:
Due to the characteristics of the RFID tag, the number of washings of the laundry can be recorded, the life of the laundry can be predicted, the inventory of the laundry can be reasonably controlled, and the user can be provided with a more scientific service.
