Wireless electronic coded lock
Abstract This design is made on the MCU module of the wireless password lock, and this design in the design of some of the practical application and some of the theoretical research in the use of knowledge。 This design is the use of wireless reception, so in the wireless module on the use of the wireless transceiver chip nRF24L01。 In the production process, using STC89C52 microcontroller as the core of the microcontroller。 In the design of the advanced language part, through the network information to gradually improve the code debugging。 This design not only gives the background and the status of the design, but also improve the design of the program and the problems encountered in the design process and solving process。 The production of information from the network to obtain the basic production principles, and then draw the corresponding design circuit drawings, after a number of debugging and testing, and ultimately improve the design。 Although the design in the production process and no much outstanding innovation, but the design process whether it is simple or complex can be used for reference and can be used to improve wireless electronic password lock both technology practice or the performance is more outstanding。
