1. System overview

This system applies RFID technology to the identification and management of individual clothes. Based on ultra-high frequency (UHF) RFID technology, it realizes an efficient work platform for fast collection, sorting, automatic inventory, and collection of clothes in the laundry industry, which greatly improves work efficiency and reduces the probability of errors. Compared with traditional manual management, this smart laundry application system has the following advantages:

A. Reduce manual management work, convenient and quick to use;

B. Improve work efficiency and economic benefits, save management personnel’s expenses, and reduce costs;

C. The system is sensitive and reliable, and the equipment is safe and durable;

D. Be able to accurately distinguish customer types and preferential services;

E. Fully automatic design to improve service quality;

F. Record and save the laundry and customer information, and you can query and print the information at any time.

2. System workflow

The clothing collection staff at the counter collect the laundry from the customer, write the customer information and clothing information into the electronic tag, and then string the electronic tag to the clothing. The clothes with electronic tags are packaged and sent to the laundry factory. The information of all the electronic tags of the laundry in the bag is read at one time through the UHF RFID reader, and the data is checked with the washing task list. After confirmation, the collection network and Handover between laundry factories. After the laundry is sorted, it enters the washing process. After washing, the clothes are sorted and packaged. The reader reads the electronic label information of all the clothes in the bag again through the reader, and checks the data with the corresponding washing task list to confirm Send it to all clothing collection outlets. When the customer picks up the clothes, the clothing collection point will check the customer’s pick-up form with the electronic label information, and after confirming that it is correct, the customer picks up the clothes.

3. Introduction to the hardware of this system

This system mainly needs hardware to complete card issuance, card reading, card writing and other functions. The hardware required is as follows:

A. Card issuer. It is specially designed for electronic label issuance, which can realize fast issuance. It has the characteristics of anti-interference.

B. Reader. A high-performance product that supports simultaneous reading of multiple tags and multiple protocols. Support 4 external antennas at the same time, which can reduce the antenna investment cost.

C. G900E external antenna. The system uses a circularly polarized antenna, so that the effect of reading and writing tags is not affected by the location of the tags, and the working distance is up to 5-7 meters.

D. Laundry label

The system uses a laundry label specially designed for the laundry industry. The label is encapsulated by rubber material and has the functions of waterproof, high strength, arbitrarily bending, high temperature resistance, and washing resistance. The label adopts EPC GEN2/ISO18000-6C international standard protocol.

4. Functional modules and features of this system

It is mainly composed of the following 8 functional modules: clothing collection at the counter, clothing collection at the counter, laundry factory handover, clothing inventory, clothing query, clothing collection statistics, customer management, and system settings.

A. Counter collection

This module is composed of a card issuing machine and a counter collection function module. Counter staff send user information and clothing through the card issuing machine.

The information is written into the card, and the information is stored in the database at the same time, and the task list is automatically generated, and the task list and the packaged clothes are transported to the laundry factory.

Features: This module can quickly complete the collection function, which is faster and more efficient than manual recording, and at the same time greatly reduces the error rate.

B. Pick up clothes at the counter

This module is composed of a card reader, a clothing taking function module at the counter, and an inventory function module. Counter staff can quickly find the clothes that customers need through the clothing inventory function. Then use the card reader to automatically complete the amount settlement of the removed clothes.

Features: This module can realize the function of fully automatic searching for clothes, which greatly improves work efficiency. At the same time, the amount settlement is completed automatically, eliminating human intervention in the amount settlement, and improving security.

C. Clothing inventory

This function consists of a card reader and an inventory function module. The operator can quickly, accurately and efficiently complete the inventory of the clothes in the store. At the same time, this functional module can also provide a quick search function to cooperate with the work of picking clothes at the counter.

Features: This module can complete automatic inventory through a card reader, which can quickly complete inventory. And is equipped with a quick search function. In the past, the tedious work was done manually, but now it can be done fully automatically.

D. Handover of laundry factory

This function is completed by the card reader and the handover function module. The transfer personnel scan the transferred clothes through the readers installed in the laundry factory, and check the scanning results with the task list to confirm whether the delivered clothes are consistent with the actual delivered clothes.

Features: This module automatically completes the confirmation of the handover work. Not only improves work efficiency, but also reduces the probability of errors.

E. Clothes query

This function is completed by the server query function module. You can query the status of all the clothes, such as the clothes being sent for washing or on the shelf, and so on. Can provide detailed data for staff and managers.

Features: It can provide more detailed data to staff and managers. You can also print and transfer the queried data to EXECL.

F. Collection statistics

This function is completed by the statistics module. Statistical data can be based on conditions such as time, customer category, etc., to provide decision-makers with a data basis for decision-making.

Features: To provide more detailed data to staff and managers. You can also print and transfer the queried data to EXECL.

G. Customer management

This function is completed by the customer management module. Finished the customer management work and provided good tools for users to manage customers.

Features: Can efficiently manage customer groups.

H, system settings

This function completes the system management of system equipment configuration, clothing types, charging standards, VIP card users, recharge, operators and passwords.
