Wireless Node Design in Smart Home System
Abstract
To solve the problems in exist product, new wireless network node for smart home system was developed based on wireless communication chip nRF24L01. The wireless network node adopted 51 series single chip microcomputer STC89C52RC as Micro Control Unit, and used nRF24L01 chip as communicator with main controller. Data Encryption Standard arithmetic is utilized as encryption method to overcome the security flaws. The designs of hardware and software were discussed in detail, as well as DES arithmetic. Finally, a system test and its performance report were given. Compared to the traditional products, the wireless network node has the advantages of cheapness, high efficiency, and security, and can be widely used in smart home system.
