Design And Implementation Of The Intelligent Lock Based On The NORDIC

With the development of the society, the requirement of people for the standard of living is becoming higher. On the one hand, the requirement for their home security is becoming higher. On the other hand, there are more and more young people away from home, and they work in the city, but they have no fixed residence, so they need to rent apartment to settle here, thus a large number of rental apartments emerged. However the requirements of landlord for the convenience and security of the collective management of rental apartments are much higher. Ordinary mechanical locks can only prevent the traditional theft; however it cannot stop the modern theft. Although the new generation of electronic smart lock(password, fingerprint and face recognition, etc.) greatly improves the security of the apartments, but when it has been damaged, the landlord cannot know it in real-time, and the smart lock cannot meet the requirement of landlord for collective management convenience of rental apartments.This paper puts forward a kind of intelligent lock system based on Bluetooth wireless network. In this system, you can control your intelligent locks on or off in your home through your mobile phone, and at the same time the condition of intelligent lock on or off can feedback on your mobile phone in real-time, it can not only know the condition of smart locks, and improve the security of the home, but also greatly facilitate the management of landlord for the rental apartments.This paper introduces though the theoretical part and the design and the implementation. For the theoretical part, this article first simply introduces the existing intelligent lock, including the background and significance of intelligent lock, domestic and foreign development present situation, the existing skill of electronic smart lock and the development trend of intelligent lock, and then using Bluetooth wireless technology. For the design and implementation of intelligent lock parts, hardware part and software part were introduced in this paper. It mainly introduced the hardware part, including the original design electric circuit, the practical application and debugging process of change, as well as the reason for its change. This paper chooses the nRF51822 chip of NORDIC as the development platform, with peripheral circuit and sensor monitoring to realize the artical.Finally, the whole test system has been explained in detail, which mainly includes final check test and single test. The final check test is the function and power test, which is to test whether the function meet the design, and whether meet the low power consumption. The single test is the require test when mass production.
