摘　　要：针对无线传输容易发生频段冲突,数据丢包等现象,采用主从分布式、双无线收发芯片、跳频技术及随机延时的思想实现点对多点的无线数传系统设计,提高无线数据传输的准确性、实时性和可靠性。该系统由单片机、主无线模块和从无线模块等组成,具有成本低廉,实现简单等优点。For the presence of frequency band conflict and data packet loss and other phenomenon in wireless transmis- sion, the paper designs a point-to-multipoints wireless data transmission system using the master-slave distributed, double wireless transceiver chips, frequency hopping technique and random delay, which improves the accuracy, real-time perfor- mance and reliability of wireless data transmission. The system consists of microcomputer, the master-wireless module and the slave-wireless module, and has the advantages of low cost and simple implementation, etc.
