Filter anti-counterfeiting technology, can read 8 anti-counterfeit labels in a distributed manner

The filter element is the continuous profit source of the manufacturer. How to ensure the purification effect of the product, how to ensure that the products of its own brand only adapt to its own filter element, how to seize the business opportunity to restore the reputation and profit?

The air purifier and water purifier market has developed rapidly, and many brands have seized their share. However, in the actual use process, it was found that many users did not replace the filter element for a long time, resulting in a decrease in purification ability, or some users carefully calculated and replaced other filter elements, resulting in no purification effect. As a result, their brand image is damaged and profits are reduced. The underlying reason is that the user is not using it properly and has difficulty in speaking.

The filter element is the continuous profit source of the manufacturer. How to ensure the purification effect of the product, how to ensure that the products of its own brand only adapt to its own filter element, how to seize the business opportunity to restore the reputation and profit?

1 Overview

As people's requirements for air quality and drinking water quality are getting higher and higher, the air purifier and water purifier market is developing rapidly. The core technology of this kind of product lies in the quality of the filter element, and it is also related to the actual effect of purification. However, in actual use, there is a case where the user does not change the filter element for a long time or replaces it with another brand filter element. Filter cartridges are consumables, and most manufacturers rely mainly on the sales of filter cartridges to make profits. So in order to ensure the actual use of the product, and how to ensure that their brand products can only adapt to their own filter? Here is the anti-counterfeiting technology of the filter element.

For this type of application, ZLG introduces a multi-channel filter anti-counterfeiting technology solution that supports up to 8 antennas and can read 8 anti-counterfeit labels in a distributed manner.

ZLG multi-channel filter anti-counterfeiting technology solution adopts Ametal modular software design idea, and combines ZLG's years of RF development design experience in NFC industry to help users quickly develop stable and reliable filter anti-counterfeit label products. At the same time, it can also provide customized services for the specific product structure requirements of users.

The water purifiers on the market usually have multiple filter elements. The following is a description of different installation methods using a water purifier of a certain structure.

Installation method 1; use 2 card reader antenna boards. The No. 1 antenna board can read the anti-counterfeit labels of the upper two filter elements, and the No. 2 antenna board can read the anti-counterfeit labels of the three lower filter elements. This method is suitable for the neat structure design of the filter element.

                                             

Installation method 2; use 5 card reader antenna boards. Each antenna board is responsible for the security label reading of one filter element. This method is flexible in installation and can adapt to the flexible and variable filter layout structure.

Multi-label anti-counterfeiting puts high demands on the equipment and personnel of the solution company. If the design idea of ​​the single antenna is still followed, the consistency will be poor during mass production, and the abnormal situation such as the anti-counterfeiting information of the filter element cannot be read. A professional network analyzer is required to complete the network analyzer with poor performance, and more than 10W. In addition to the instrument, the experience and quality of the designer is also very important, and the calibration of the instrument requires professional steps.

ARKS16F5xxN is a series of integrated card reader hardware and Ametal software developed by Guangzhou Zhou Ligong MCU Technology Co., Ltd. It integrates MCU internally, and users can realize multi-channel filter anti-counterfeiting solution simply, quickly and efficiently.

The user does not need to debug the complex card reader antenna resonant circuit on the hardware. It only needs to add Power Supply, connector and other circuits to the peripheral to achieve the solution.

In software, users do not need to develop the underlying card reader module driver, as long as they pay attention to the development of the application. Reliable mass production of the solution is quick and easy.
