基于433MHz和WiFi技術(shù)的無線智能鎖系統(tǒng)
[Abstract]:With the development of science and technology, intelligent lock, as an important part of smart home, has been paid more and more attention. At the same time, how to make the door lock more convenient and intelligent has become the focus of current research. Wi Fi technology, as an important wireless communication technology, has a very high mobile terminal share today. People are getting more and more popular. Mobile terminals such as IP IP are connected to AP via WiFi wireless signal. The advantage of wireless broadband service. Wi Fi is that almost all mobile terminals are supported, and the transmission speed is fast and widespread, so it is the most widely used wireless network communication technology. Because of its high power consumption and poor signal penetration diffraction ability, it can not fully meet the requirement of wireless intelligent locking system. 433MHz band is the ISM band without application. The wireless module developed based on this band has long communication distance and good anti-attenuation capability. Strong signal penetration and many other advantages. Combining the advantages of WiFi and 433MHz wireless module, this paper introduces a wireless intelligent locking system based on 433MHz and WiFi technology. In this paper, we first introduce the commonly used communication technology, and analyze their advantages and disadvantages; then according to the system requirements, put forward the system scheme; then the specific implementation of the system, including the design of the software and hardware of the communication module, The development of mobile terminal; finally, the communication between modules, network communication test. In the design of wireless module, the microcontroller, the selection of RF transceiver chip, the design of RF transceiver circuit, the analysis of communication process and the realization of communication are emphasized. In the development of client, the development environment of PC client and Android client is introduced, the process of data communication is analyzed and the corresponding function is explained with concrete interface. The wireless intelligent lock system based on 433MHz and WiFi technology is designed in this paper. The wireless intelligent lock system can effectively utilize the mobile terminal, the user can open the door lock by one click of the mobile terminal, and the user can monitor the door lock action in real time through the PC client. The management of credit card information can effectively prevent the theft of illegal elements.
