Low Power Design and New Energy Utilization of Fingerprint Lock

With the development of science and technology, people's requirements for security are getting higher and higher, and smart door locks, as a part of smart home, have great advantages in security. Among them, fingerprint lock is widely used because of its convenience and high security. However, the traditional fingerprint lock has some problems, such as high power consumption and short battery life. Therefore, this paper will focus on the low-power design and new energy utilization of fingerprint lock.

1. Research on Low Power Design Technology

1. Optimize the hardware structure: reduce energy consumption by improving the design and manufacturing process of key components such as sensors; Adopt advanced microprocessor and memory to reduce working voltage and current and improve energy utilization.

2. Algorithm optimization: realize the effective management of system resources at the software level, and reduce the computational complexity through a reasonable algorithm scheduling mechanism, thereby reducing the CPU load and memory occupation, and finally achieving the purpose of reducing the overall power consumption.

3. Intelligent mode switching: according to different scene requirements (such as day or night), automatically adjust the running state of equipment to save power resources. For example, when it is set to night mode, only the necessary functional modules can be turned on and the screen brightness can be reduced.

Second, the new energy utilization mode

1. Photovoltaic power supply scheme: using solar panels to generate electricity to charge the fingerprint lock, which is environmentally friendly, economical and practical;

2. Wind turbine: In some areas, especially in coastal cities with high wind speed, the power generated by small wind turbines can also be considered to provide power support for fingerprint locks;

3. Energy collection technology: the mechanical energy such as waste heat or vibration in the environment is converted into electrical energy for the fingerprint lock to work.

III. Conclusion

To sum up, we can see that it is feasible and necessary to realize the low-power design and new energy utilization of fingerprint lock. This can not only effectively extend the battery life and enhance the user experience; More importantly, it can respond to the call for energy conservation and emission reduction, and promote the concept of green and low-carbon life to be deeply rooted in the hearts of the people. In the future, we can explore more innovative technologies and materials to make our products more intelligent and humanized. At the same time, we call on manufacturers to pay attention to R&D investment and push the whole industry to a higher level!
