摘　　要：针对反恐排爆任务的特殊性以及固定载波频率的无线通信系统在数据发射和接收过程中,信息易受到干扰、破坏、截获等导致丢失的问题,设计了一种基于STM32和nRF905的低成本低功耗的反恐排爆机器人跳频通信系统。文中给出了系统的软硬件设计及实现方法,描述了软件跳频协议的实现方式,设计了软件跳频协议来提高系统在同频干扰下的抗干扰能力。实验结果表明:通信收发双方在1000 m的范围内,该系统可以有效地避免同频干扰,提高系统传输的可靠性。According to the particularity of anti-terrorist EOD tasks, a low-cost and low-power frequen-cy hopping communication system of explosive-handling robot based on STM32 and nRF905 was de-signed for solving the problems of the fixed carrier frequency being vulnerable to interference, destruc-tion, intercept etc of the wireless communication system, which resulted in the loss of information in the data transmitting and receiving process. The design of the system,s hardware and software was intro-duced, the implementation method of software frequency hopping protocol was described, and the proto-col was designed to improve the system,s anti-interference ability under the same frequency. The exper-imental results indicate that the system can avoid same frequency interference effectively, and improves the transmission reliability in the range of 1000 m between the two communication sides.
