RFID
Usually used in access control systems, food safety traceability, etc., NFC is used in mobile payment, electronic payment, identification, card punching, access control, secure login, logistics, bills, etc. Today, these two wireless communication technologies are present in smart washing machines in smart homes.
NXP has launched a smart washing machine solution using RFID and NFC technology, the washing machine can beRFIDThe color and texture of the clothes are automatically detected in the buttons of the label, and the washing program can be optimized according to the characteristics of the clothes and detergents. On the mobile phone with NFC function, the smart washing machine can be controlled remotely, and the working mode or status of the washing machine can be changed.
Mei Runping, global senior sales director of NXP Semiconductors’ home appliance application market, demonstrated the smart washing machine. When the clothes are put into the drum of the washing machine, the color of the clothes will be displayed on the computer software window, and the characteristics of the detergent can also be read. Then carry out intelligent mode setting and operation.
And this smart washing machine can provide a variety of settings suitable for different temperatures, cycles and fibers, all of which are controlled by a single board. The demo machine uses the LPC1227, a 32-bit ARM core Cortex-MO platform with a low gate count. microprocessor. Compared with previous 8-bit MCUs, the LPC1227 can significantly improve system performance and functionality, enabling power monitoring, NFC,RFIDand other functions, and using the internal RC oscillator, the accuracy can reach 1%.
Another highlight is that NXP’s GreenChip highly integrated power management IC can achieve a minimum power consumption of less than 10mW in standby mode, and the system can wake up quickly from standby mode.
NXP’s exploration of the limitless possibilities of two-way communication is just beginning. In the future, functions such as NFC will become an essential function of terminal products such as mobile phones and computers. In this way, as long as supporting application software is added, the promotion of NFC and other technologies in home appliances will be realized, and the intelligent intercommunication between smart terminals and home appliances will be easily realized. .
