摘要
鉴于目前多数对讲设备安全性低、信号不稳定、易冲突、使用频率许可等问题,设计了一种以ZigBee为通信技术的语音对讲系统.明显改善了上述问题.该系统终端以单片机MSP430F149为微处理器,通过使用TI公司提供的CC2430射频芯片,应用ZigBee无线通信标准相关技术,在所设计的节点硬件试验平台上,组建ZigBee星型网络实现语音通信,并且对整个系统进行测试.测试结果表明,利用ZigBee技术进行无线语音通信是具有优越性的,并且满足了无线个域网网络对功耗和传输的要求.
Whereas most of the low security intercom equipment, signal instability, conflict-prone, frequency of use license and other issues, the paper design of a ZigBee as communication technology to voice intercom system, significantly improved the above-mentioned problems. Terminal to the system microcontroller MSP430F149 microprocessor, provided through the use of TI CC2430 RF chip, ZigBee wireless communication standard, appli- cation technology related to the node in design, hardware test platform, the formation of ZigBee star network realization voice communication, of the entire system tests. Test results show that, using the ZigBee wireless technology has the advantages of voice communication, and meet the WSN network of power and transmission requirements.
