Mei Runping, global senior sales director of NXP Semiconductors’ home appliance application market, emphasized that it is the first time in the semiconductor industry to realize such a broad product portfolio in one home appliance. “The trend of intelligent household appliances is increasing day by day, but our exploration of the infinite possibilities of two-way communication has only just begun.†Mei Runping said, “In the future, NFC and other functions will become essential features for mobile phones, computers and other terminal products, so that only by adding The supporting application software can realize the promotion of NFC and other technologies on home appliances. Intelligent interoperability between smart terminals and home appliances will be easily realized."
The most notable feature of this demonstration is the Fabric and Detergent Recognition function: the washing machine can read the information of fabric fiber types and colors from the buttons on the built-in RFID tags, helping to avoid mixing the white and black clothes together, and The washing program can be optimized based on the characteristics of the clothes and detergents read; another outstanding feature is its NFC-based maintenance function: authorized maintenance technicians can remotely use the NFC-enabled mobile phone for smart washing machines. Diagnose, change its working status, start related applications that can directly communicate with the specified service center, and so on.
The data provided by NXP shows that currently, the top 10 large home appliances companies in the world occupy about 55% of the market share. It is estimated that by 2015, the demand for semiconductor products from large appliances will increase by 15% per year, and the quota will reach US$2 billion; while the small household appliances market is very fragmented, the top ten small appliance manufacturers can only occupy less than 40% of the total. Shares, profits more from some high-end applications, such as Italian coffee machines. To this end, NXP has also made corresponding adjustments to its organizational structure and established the vertical application department represented by AEA (Appliance/Energy/Automation) to meet the opportunities and challenges brought about by the Next Generation Internet of Things (The Internet of Things).
In addition to fabric fiber detection and NFC capabilities, the demonstration model also uses a 32-bit microcontroller LPC1227 based on the ARM Cortex-M0 platform for user interface and system management of complex wash programs. Mei Runping said that RFID and NFC technology extend to the field of home appliances, intelligent washing machines with this feature can provide a variety of settings for different temperatures, cycles and fibers, and all functions will all use a single board to control.
According to NXP, the LPC1227 code density is increased by approximately 50% compared to conventional 8-bit MCUs. Internally, an RC oscillator with an accuracy of 1% can drive high-current GPIO, deterministic partitioning algorithms in ROM, and has passed the IEC 60730 safety standard. Certification. As part of the demonstration session, NXP also demonstrated how the LPC1227 can be used directly to drive the high-interference TRIACBTA316 and ACT108 without any other drive scheme.
Other highlights of the demonstration include: 1. The use of an efficient GreenChipTEA1721 switching power supply controller IC with integrated MOSFETs consumes less than 10mW in standby mode. The system can quickly wake up from the standby mode and return to full operation state; 2. The intelligent washing machine can effectively monitor and display its own power consumption, and remotely transmit the power consumption data to the relevant service center or power supplier; 3. Via IEEE802. 15.4 Wireless communication with smart meters or energy gateways. This smart washing machine demonstration model uses FCC and ETS standard modules, built-in ultra-low power JN5148 wireless controller. The module supports a wide range of protocol stacks, including ZigBeePRO smart energy and home automation, JenNet-IP (6LoWPAN) and RF4CE remote control.
