摘要
针对无线通信中采用固定载波频率发射和接收导致信息容易被跟踪、截获、破解的问题,从提高通信信息的安全性出发,采用单片机控制单芯片射频收发芯片nRF905构成无线跳频通信系统,通过改变载波频率防止信息被截获和破解,提高了信息的安全性,通过通信方案的优化,提高了系统的安全性和可靠性,系统测试性功能良好。
In order to solve the problem of the existing wireless communication system,that is the communication in a fixed carrier frequency can lead to that the information may be tracked,intercepted and cracked.To improve the security of communications,a wireless frequency-hopping communication system is designed using the nRF905 and a single-chip RF transceiver chip.Changing the carrier frequency can prevent the information from being intercepted and cracked to improve the security of information.The communication program optimization can improve the system security and reliability.The function of system testing is good.
