摘　　要： 无线扩音系统能解决许多实际工程中的布线和移动使用的难题。无线传输的方式也从传统的U段、V段无线扩音发展到包括红外线、蓝牙和2.4 GHz频段在内的无线数字传输方式。数字无线扩音系统可广泛应用在教学、会场、现代办公、家居等领域。文中介绍基于ATmega8的低成本无线智能跳频数码扩音系统设计,利用智能跳频询址技术,可使发射机可更迅速地自动被接收机识别,任意发射机可以匹配任意接收机。 Wireless microphone system has been used to solve many engineering issues, such as to replace wiring, mobile use, etc. From the traditional U, V band mechanism, the wireless transmission has been developed in digital transmission via Infrared, Bluetooth and 2. 4 GHz wireless band technology. Wireless digital microphone system can be widely used in classrooms, venues, offices, homes and other fields. This paper presents an ATmega8- based low cost wireless digital microphone with an intelligent frequency hopping technique for channel address enquiry, which allows transmitter to be automatically recognized more quickly by the receiver. Any receiver can be matched with any transmitter.
