Recently, the research team of Chongqing Intelligent Engineering Vocational College and Huawei (Yongchuan) joint technology innovation center, located in Yongchuan, Chongqing, successfully developed a radiation free long-distance wireless power supply transmitter chip. Based on the strong coupling resonance mechanism of the magnetic field, the chip successfully realizes radiation free, long-distance wireless power transmission. It can take power freely within 1.5 meters under low-power load, and the charging efficiency can reach more than 80%.

On May 17, Qian Yonggang, a teacher from Chongqing Intelligent Engineering Vocational College, showed off the control chip for the transmitter of long-distance wireless power supply without radiation developed by the school's scientific research team.

It is understood that after the first generation of experimental prototype design of the radiation free long-distance wireless power supply transmitter control chip is completed, the prototype developed has many problems to be solved, such as large volume, high energy consumption, low efficiency, small transmission distance and so on. With the cooperation and support of Huawei technical experts, the members of the scientific research team of the university successfully designed the wireless power transmission integrated circuit cqai-0512a, with built-in RF transmission circuit and 8-bit CMOS MCU. The chip supports ask debugging mode. It has the advantages of high integration, automatic frequency locking, automatic load detection, automatic power regulation, low power consumption, low cost and high power, and solves many problems at the transmitter.

Radio energy transmission technology can get rid of the shackles of traditional wires, improve the freedom of power supply, and bring about a revolution in product convenience. Therefore, it is considered to be one of the most anticipated technologies in the 21st century.

Take real estate as an example. As intelligent technology is increasingly integrated into daily life, buyers expect new houses to become more intelligent. This is why new home builders have recently attached great importance to the direct integration of smart devices into new homes.

Previously, builders provided wired rooms with built-in Ethernet interfaces to make it easier to connect to the Internet. Wi Fi makes this practice obsolete. Most homeowners prefer to set up Wi Fi routers rather than plug into Ethernet ports in each room. Therefore, it is not surprising that home builders are turning to a novel technology to enhance their appeal to technology savvy buyers: wireless power supply. We have seen that many enterprises carry out business in the field of radio energy transmission. By integrating long-distance wireless power supply technology from the beginning of construction, builders hope to attract a new generation of eco conscious, innovation driven home buyers.

However, smart devices have become a reality, not just a fashion. It is estimated that there will be nearly 93million smart home families in North America by 2025. This is why builders are trying to adapt their houses to smart devices.

Smart devices have become a major selling point for home builders. Remote wireless charging is an innovative technology that promotes the widespread use of intelligent devices. It is a novel technology that is expected to provide a simple solution for charging intelligent devices and supplying power in areas where wires are not actually used.

The remote wireless power supply is different from the charging board of the mobile phone. Charging boards are useful, but from a user experience point of view, they are a new version of the docking station we used for cordless phones 20 years ago. The charging board requires a power cord, and the user needs to carefully place the device on the board and align it to charge. Isn't it good if the device can charge automatically? This is the source of remote wireless power supply.

Long distance wireless power supply can supply power from a long distance without wires. The power transmitter is located on one side of the room, and the charged equipment includes the power receiver. Remote power supply can be obtained through a variety of technologies, including radio frequency (RF), ultrasonic and infrared (IR) light.

For builders who have invested in building smart homes, wireless charging provides an opportunity to expand the appeal of IOT and connectivity. A survey shows that more than 65% of paywall buyers will pay higher prices for houses equipped with smart home technology. When this smart home technology has continuous power supply, builders can ask for high prices.

Smart device failure will bring huge costs to home builders, because homeowners hope that the builders will bear and abide by the installation guarantee. Remote wireless charging can help ensure that smart devices are always charged, thereby reducing manufacturers' related warranty costs. Similarly, through wireless charging, home builders will no longer need to wire wires to many devices, thereby saving material and labor costs.

When installed in multi family homes, smart devices can also help property managers. Intelligent thermostats help reduce energy costs and make more efficient use of resources. Using smart locks can easily change the code when the tenant leaves, or assist in authorized entry, such as delivering packages.

Commercial houses equipped with wireless power supply can help new houses stand out in the increasingly competitive real estate market. This is true for houses of all sizes: from smaller urban apartments to large suburban real estate. For both builders and buyers, wireless power supply is a wise choice.

Chongqing big data industry research institute and other platforms have comprehensively promoted scientific and technological innovation, adhered to the integrated development of industry, education and science, and improved the ability of scientific and technological innovation. Focusing on artificial intelligence, big data and other fields, they have developed a series of innovative achievements, such as smart health cabin, contactless millimeter wave radar respiratory and heart rate detection system, smart agricultural control system, passive Internet of things control system, and some of them have been put into use.

With the vigorous development of manufacturing industries such as consumer electronics, industrial Internet of things devices, smart wear, biomedical devices, motorcycles, AGVs, robots and so on, the smart consumer device market is gradually expanding, and long-distance, low-power, radiation-free wireless charging has become the future trend.
